ABSTRACT

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on NLRP3 inflammasome and its downstream protein gastermin D (GSDMD) in rats with primary dysmenorrhea (PDM), and to explore the potential mechanism of EA on the treatment of PDM.@*METHODS@#Forty healthy female SD rats without pregnancy were randomly divided into a control group, a model group, an EA group and an ibuprofen group, 10 rats in each group. PDM model was prepared by injection of estradiol benzoate and oxytocin. Except the control group, the rats in each group were subcutaneously injected with estradiol benzoate for 10 days, and oxytocin was injected on the 11th day. The rats in the EA group were intervened with EA (dense wave, frequency of 50 Hz) at "Guanyuan" (CV 4) and "Sanyinjiao" (SP 6) at the same time of modeling, once a day, 20 min each time, for 10 consecutive days. The rats in the ibuprofen group were treated with 0.8 mL of ibuprofen by gavage (concentration of ibuprofen solution was 1.25 mg/mL) for 10 consecutive days. After modeling, the writhing reaction was observed. After intervention, the HE staining method was used to observe the histological morphology of uterus and evaluate the pathological damage score of uterus; ELISA method was used to detect the serum levels of prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α); Western blot method was used to detect the protein expression of NLRP3, apoptosis related spot like protein (ASC), caspase-1, GSDMD, GSDMD-N and inflammatory factors (interleukin [IL]-1β, IL-18) in uterine tissue.@*RESULTS@#In the model group, a large number of vacuolar degeneration and death of endometrial epithelial cells, spiral arterioles congestion in lamina propria and neutrophil infiltration were observed. In the EA group, there was a small amount of vacuolar degeneration and death of endometrial epithelial cells, a small amount of spiral arterioles congestion in the lamina propria, and a small amount of neutrophils infiltration. In the ibuprofen group, there was very small number of degeneration and death of endometrial epithelial cells, and no obvious arterial congestion was found in lamina propria, and neutrophil infiltration was occasionally seen. Compared with the control group, in the model group the number of writhing was increased (P<0.01), the writhing reaction score and serum level of PGF2α and PGF2α/PGE2 value were increased (P<0.01), the level of PGE2 was decreased (P<0.01). Compared with the model group, in the EA group and the ibuprofen group the number of writhing were decreased (P<0.05), the latency of writhing was prolonged (P<0.01), the writhing reaction scores and serum levels of PGF2α and PGF2α/PGE2 values were decreased (P<0.05, P<0.01), the levels of PGE2 were increased (P<0.01). Compared with the control group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was increased in the model group (P<0.01). Compared with the model group, the protein expression of NLRP3, ASC, caspase-1, GSDMD, GSDMD-N, IL-1β and IL-18 in the uterine tissues of rats was decreased in the EA group and the ibuprofen group (P<0.01, P<0.05). There was no significant difference between the EA group and the ibuprofen group in the above indexes (P>0.05).@*CONCLUSION@#EA could alleviate pain and uterine tissue injury in rats with PDM. The mechanism may be related to the inhibition of the activation of NLRP3 inflammasome in rat uterine tissues, thereby inhibiting pyroptosis and its inflammatory factors release.

ABSTRACT

This study aimed to investigate the therapeutic effect of Leonuri Herba aqueous decoction on primary dysmenorrhea(PD) and explore the underlying mechanism in conjunction with untargeted metabolomics. Forty adult female rats were randomly divi-ded into a normal group, a model control group, ibuprofen(0.12 g·kg~(-1)) group, and high-and low-dose Leonuri Herba aqueous decoction(5 and 2.5 g·kg~(-1)) groups, with eight rats in each group. The PD rat model was prepared using intramuscular injection of estradiol benzoate combined with intraperitoneal injection of pitocin. Drugs were administered by gavage from the 4th day of modeling for 7 d. After the last administration, pitocin was injected intraperitoneally, and the writhing latency and writhing times within 30 min were recorded. The uterine and ovarian coefficients were determined. Estradiol(E_2), progesterone(Prog), oxytocin(OT), cyclooxyge-nase 2(COX-2), prostaglandin E_2(PGE_2), prostaglandin F_(2α)(PGF_(2α)), and Ca~(2+) levels in uterine tissues were measured by ELISA and biochemical kits. Morphological changes in uterine and ovarian tissues were observed by hematoxylin-eosin(HE) staining. The protein expression of oxytocin receptor(OTR), prostaglandin E_2 receptor 3(EP3), and estrogen receptor alpha(ERα) in uterine tissues was detected by immunohistochemistry. The mRNA expression of OTR, PGE_2 receptors 1-4(EP1, EP2, EP3, and EP4), and PGF_(2α) receptor(FP) in uterine tissues was detected by quantitative real-time PCR. Untargeted metabolomics analysis was performed by ultra-high-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(LC-QTOF-MS) technology to screen potential biomarkers and enrich metabolic pathways. The results showed that Leonuri Herba was able to significantly reduce the writhing times in PD rats(P<0.05 or P<0.01), significantly reduce the uterine and ovarian coefficients(P<0.01), and improve their histomorphology. After treatment with Leonuri Herba, PGE_2 content was significantly increased(P<0.05), COX-2, PGF_(2α) and Ca~(2+) content, and PGF_(2α)/PGE_2 was significantly decreased(P<0.05 or P<0.01), and OT content was decreased, while E_2 and Prog content tended to further increase in uterine tissues of PD rats. Correspondingly, OTR and EP3 protein expression was significantly downregulated(P<0.05 or P<0.01) and ERα protein expression was upregulated(P<0.05) in uterine tissues. The mRNA expression of FP and EP4 in uterine tissues was significantly downregulated(P<0.01), and the mRNA expression of EP1, EP3, and OTR showed a decreasing trend. The untargeted metabolomics results showed that 10 differential metabolites were restored in the plasma of PD rats after Leonuri Herba treatment. The results indicate that Leonuri Herba is effective in the prevention and treatment of PD, and the underlying mechanism may be attributed to the regulation of PGs synthesis and corresponding receptor binding.

ABSTRACT

This study aimed to evaluate the role of prostaglandin F2α (PGF) on ovulation. In Experiment 1, cows were randomly allocated to two treatments to receive 150 µg of d-Cloprostenol (PGF Group, n = 12) or 2 mL of NaCl 0.9% (Control Group, n = 11) and CIDRs, were removed 4 days later. No cow ovulated in Control and PGF groups. In Experiment 2, cows were randomly separated into two experimental groups to receive 4 injections of 150 µg of d-Cloprostenol (n = 9) or 2 mL of NaCL 0.9% (n = 9). In this experiment, ovulation was not observed in any cows. In Experiment 3, ovariectomized cows receive three injections of 300µg of PGF analog (PGF Group, n = 5), 100µg of Lecirelin (GnRH Group, n = 5) or 2 mL of PBS (Control Group, n = 4). The LH concentration was higher (P <0.0001) in cows from the GnRH group than in the PGF and Control groups. In experiment 4, cows with preovulatory follicles (>11.5 mm) were treated with Saline (Control Group, n = 6); Lecirelin (GnRH Group, n = 7) or Cloprostenol Sodium (PGF Group, n = 6). There was a significant increase in the vascular area of follicles from 0 to 24 h in GnRH and PGF treatments. In conclusion, PGF was not able to induce ovulation in cows with high or low plasma progesterone concentration. Additionally, PGF alone was not able to induce LH release and follicle luteinization, but increased follicular vascularization.(AU)


O objetivo deste estudo foi avaliar o papel da prostaglandina F2α (PGF) na ovulação. No Experimento 1, as vacas foram alocadas aleatoriamente em dois tratamentos para receber 150 µg de d-Cloprostenol (Grupo PGF, n = 12) ou 2 mL de NaCl 0,9% (Grupo Controle, n = 11) e os CIDR, foram removidos 4 dias depois. Nenhuma vaca ovulou nos grupos Controle e PGF. No Experimento 2, as vacas foram separadas aleatoriamente em dois grupos experimentais para receber 4 injeções de 150 µg de d-Cloprostenol (n = 9) ou 2 mL de NaCL 0,9% (n = 9). Não foi observada ovulação em nenhum dos animais deste experimento. No Experimento 3, vacas ovariectomizadas receberam três injeções de 300µg de análogo de PGF (Grupo PGF, n = 5), 100µg de Lecirelina (Grupo GnRH, n = 5) ou 2 mL de PBS (Grupo Controle, n = 4). A concentração de LH foi maior (P <0,0001) nas vacas do grupo GnRH do que nos grupos PGF e Controle. No Experimento 4, vacas com folículos pré-ovulatórios (> 11,5 mm) foram tratadas com solução salina (Grupo Controle, n = 6), Lecirelina (Grupo GnRH, n = 7) ou Cloprostenol Sódico (Grupo PGF, n = 6). Houve um aumento significativo na área vascular dos folículos de 0 a 24h nos tratamentos com GnRH e PGF. Em conclusão, a PGF não foi capaz de induzir ovulação em vacas com alta ou baixa concentração plasmática de progesterona. Além disso, a PGF sozinha não foi capaz de induzir a liberação de LH e a luteinização do folículo, mas aumentou a vascularização folicular.(AU)

ABSTRACT

BACKGROUND: PGF2α is essential for the induction of the corpus luteum regression which in turn reduces progesterone production. Early growth response (EGR) proteins are Cys2-His2-type zinc-finger transcription factor that are strongly linked to cellular proliferation, survival and apoptosis. Rapid elevation of EGR1 was observed after luteolytic dose of PGF2α. EGR1 is involved in the transactivation of many genes, including TGFß1, which plays an important role during luteal regression. METHODS: The current study was conducted in buffalo luteal cells with the aim to better understand the role of EGR1 in transactivation of TGFß1 during PGF2α induced luteal regression. Luteal cells from mid stage corpus luteum of buffalo were cultured and treated with different doses of PGF2α for different time durations. Relative expression of mRNAs encoding for enzymes within the progesterone biosynthetic pathway (3ßHSD, CYP11A1 and StAR); Caspase 3; AKT were analyzed to confirm the occurrence of luteolytic event. To determine if EGR1 is involved in the PGF2α induced luteal regression via induction of TGFß1 expression, we knocked out the EGR1 gene by using CRISPR/Cas9. RESULT: The present experiment determined whether EGR1 protein expression in luteal cells was responsive to PGF2α treatment. Quantification of EGR1 and TGFß1 mRNA showed significant up regulation in luteal cells of buffalo at 12 h post PGF2α induction. In order to validate the role of PGF2α on stimulating the expression of TGFß1 by an EGR1 dependent mechanism we knocked out EGR1. The EGR1 ablated luteal cells were stimulated with PGF2α and it was observed that EGR1 KO did not modulate the PGF2α induced expression of TGFß1. In PGF2α treated EGR1 KO luteal cell, the mRNA expression of Caspase 3 was significantly increased compared to PGF2α treated wild type luteal cells maintained for 12 h. We also studied the influence of EGR1 on steroidogenesis. The EGR1 KO luteal cells with PGF2α treatment showed no substantial difference either in the progesterone concentration or in StAR mRNA expression with PGF2α-treated wild type luteal cells. CONCLUSION: These results suggest that EGR1 signaling is not the only factor which plays a role in the regulation of PGF2α induced TGFß1 signaling for luteolysis.

ABSTRACT

Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several molecular pathways in endometrial cells, including the synthesis of PGF2α; however, its specific mechanisms are still not totally known. This study investigated the production in vitro and possible modulation of endometrial PGF2α due to a local effect of endogenous E2 in the ipsilateral uterine horn (UH) containing the dominant follicle (DF) or from P4 in ipsilateral horn containing the corpus luteum (CL). The PGF2α stimulators oxytocin (OT) and phorbol 12,13-dibutyrate (PDBu) were incubated with endometrial explants, and PGF2α content was measured. For that, cycling cows were synchronized, the development of DF and CL was examined by ultrasonography and on the seventh day of the estrous cycle, endometrial explants were collected and cultured in medium supplemented with 10-6 M PDBu or 10-6 M OT or non-supplemented. Media samples were collected immediately after treatment and 60 min later. Radioimmunoassay showed that the PGF2α content of the UH ipsilateral to the DF was 49% less than that of the contralateral UH (8.22 ± 0.95 vs. 12.24 ± 0.95 pg/mL/mg tissue, respectively; P < 0.01). However, the PGF2α levels did not differ between the UHs as a function of the CL position (9.46 ± 0.95 vs. 11 ± 0.95 pg/mL/mg; P > 0.05). The cellular stimulators promoted an increase in PGF2α synthesis (P < 0.02), and the effects differed among the animals (P < 0.04). The PGF2a production was higher in the explants treated with PDBu rather than OT (13.68 ± 1.16 vs. 10.01 ± 1.16 pg/mL/mg tissue, respectively; P < 0.05). In conclusion, PGF2α synthesis is modulated by the presence of the DF (local E2) but not the CL (local P4), and both PDBu and OT stimulated PGF2a synthesis.(AU)


A prostaglandina F2α (PGF2α) determina a luteólise em bovinos. A capacidade de manipular sua síntese endógena é indispensável para a produção animal em grande escala. O estradiol (E2) e a progesterona (P4) modulam diversas vias moleculares das células endometriais, incluindo a síntese de PGF2α; no entanto, pouco se sabe sobre seus mecanismos específicos. Este trabalho investigou a produção in vitro e a possível modulação da PGF2α endometrial devido a um efeito local do E2 endógeno no corno uterino ipsilateral ao folículo dominante (FD) ou da P4 no corno ipsilateral ao corpo lúteo (CL). Os estimuladores de PGF2α oxitocina (OT) e 12,23-dibutirato de forbol (PDBu) foram incubados com explantes endometriais, e o conteúdo de PGF2α foi mensurado. Para tal, vacas cíclicas foram sincronizadas, o desenvolvimento de FD e CL foi examinado por ultrassonografia, e no 17º dia do ciclo estral os explantes endometriais foram coletados e cultivados em meio ou suplementados com PDBu 10-6M ou 10-6M OT. As amostras de meio foram coletadas imediatamente após o tratamento e sessenta minutos depois. O radioimunoensaio mostrou que o conteúdo de PGF2α do corno ipsilateral ao FD foi 49% menor que o do corno contralateral (8,22 ± 0,95 vs. 12,24 ± 0,95 pg/mL/mg de tecido, respectivamente, P < 0,01). No entanto, os níveis de PGF2α não diferiram entre os cornos em função da posição do CL (9,46 ± 0,95 versus 11 ± 0,95 pg/mL/mg; P > 0,05). Os estimuladores celulares promoveram um aumento na síntese de PGF2α (P < 0,02), e os efeitos diferiram entre os animais (P < 0,04). A produção de PGF2α foi maior nos explantes tratados com PDBu em comparação à OT (13,68 ± 1,16 versus 10,01 ± 1,16 pg/mL/mg de tecido, respectivamente, P < 0,05). A conclusão obtida foi que a síntese de PGF2α é: modulada pela presença do FD (E2 local), mas não do CL (P4 local); e estimulada por PDBu e OT.(AU)

ABSTRACT

ABSTRACT BACKGROUND: Ostomy is a surgical procedure that creates a stoma that aims to construct a new path for the output of feces or urine. The relationship of oxidative stress (OxS) markers in patients with ostomy is still poorly described. OBJECTIVE: The present study was aimed at investigating the changes in oxidative stress parameters in peripheral blood collected from ostomy patients when compared with a healthy control group. METHODS: It was evaluated 29 ostomy patients and 30 healthy control patients. The oxidative stress parameters evaluated were: lipid peroxidation [lipid hydroperoxide (LPO), 8-isoprostane (8-ISO) and 4-hydroxynonenal (4-HNE)], protein oxidation and nitration [carbonyl and 3-nitrotyrosine (3-NT)] and DNA oxidation [8-hydroxy-2'-deoxyguanosine (8-OHDG)] in serum from ostomy patients compared to health controls. RESULTS: The data showed an increase of LPO, 8-ISO, 4-HNE, 3-NT and 8-OHDG in serum collected from ostomy patients when compared to healthy controls. CONCLUSION: The findings support the hypothesis that ostomy triggers the oxidative stress observed in the blood collected from these patients.


RESUMO CONTEXTO: Ostomia é um procedimento cirúrgico que cria um estoma com objetivo de construir um novo caminho para a saída das fezes ou urina. A relação dos marcadores de estresse oxidativo em pacientes ostomizados ainda é pouco descrita. OBJETIVO: O presente estudo tem como objetivo investigar as alterações dos parâmetros de estresse oxidativo em sangue de pacientes ostomizados comparados a controles saudáveis. MÉTODOS: Foram avaliados 29 pacientes ostomizados e 30 controles saudáveis. Os parâmetros de estresse oxidativo avaliados foram: peroxidação lipídica [hidroperóxido de lipídio (LPO), 8-isoprostano (8-ISO) e 4-hidroxinonenal (4-HNE)], oxidação e nitração de proteínas [carbonila e 3-nitrotirosina (3-NT)] e oxidação do DNA [8-hidroxi-2'-desoxiguanosina (8-OHDG)] em soro de pacientes ostomizados comparados a controles saudáveis. RESULTADOS: Os dados mostraram um aumento de LPO, 8-ISO, 4-HNE, 3-NT e 8-OHDG em soro de pacientes ostomizados em comparação a controles saudáveis. CONCLUSÃO: Os achados sustentam a hipótese de que a ostomia desencadeia o estresse oxidativo observado no sangue coletado destes pacientes.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of total flavone of haw leaves (TFHL) on the expression of nuclear factor erythroid-2 related factor (Nrf2) and other related factors in nonalcoholic steatohepatitis (NASH) rats induced by high-fat diet and then to further discuss the mechanism of TFHL's prevention against NASH.</p><p><b>METHODS</b>High-fat diet was fed to 40 rats to establish the NASH model. Then model rats were intragastrically administrated with 40, 80, 160 mg/(kg•day) TFHL, respectively. The pathological changes of liver tissues in NASH rats were detected by oil red O and hematoxylin-eosin (HE) stainings. The expression of Nrf2 in rat liver was examined through immunohistochemistry. The level of 8-iso-prostaglandin F2α in serum was detected through enzyme linked immunosorbent assay (ELISA). The mRNA and protein levels of Nrf2 and other related factors in liver tissue were measured by real-time reverse transcriptionpolymerase chain reaction and western blot.</p><p><b>RESULTS</b>Lipid deposition, hepatic steatosis, focal necrosis in lobular inflammation and ballooning degeneration were emerged in livers of NASH rats. The 8-iso-prostaglandin F2α in the serum of NASH rats increased significantly compared with the control group (P<0.05). The mRNA of Nrf2, hemeoxyenase1 (HO-1) and the mRNA and protein levels of quinine oxidoreductase (NQO1) in NASH rats liver tissue showed a striking increase, while the mRNA levels of Keap1, r-glutamylcysteine synthethase (rGCS) and glutathione S-transferase (GST) were significantly decreased compared with the control group (P<0.05). After TFHL treatment, 8-iso-prostaglandin F2α level in serum significantly decreased, and Nrf2 mRNA and protein levels in hepatocytes nucleus enhanced compared with the model group (P<0.05 or 0.01). Meanwhile the Keap1 mRNA, the mRNA and protein levels of HO-1, NQO1 antibody, rGCS antibody, GST increased after TFHL treatment (P<0.05 or 0.01).</p><p><b>CONCLUSIONS</b>Nrf2 and other related factors were involved in development of NASH, and they also served as an important part in its occurrence. By regulating expression of Nrf2 and other related factors, TFHL may play a role in antioxidative stress and prevention of NASH.</p>

ABSTRACT

ABSTRACT Objective The objective of this study, in addition to confirming that therapy with 131I causes oxidative stress, was to evaluate the effect of supplementation with vitamins C and E and selenium on this phenomenon by measuring plasma 8-epi-PGF2a, a marker of lipid peroxidation. Subjects and methods Forty patients with thyroid cancer submitted to thyroidectomy, who received 3.7 GBq 131I after levothyroxine withdrawal, were selected; 20 patients did not receive (control group) and 20 patients received (intervention group) daily supplementation consisting of 2000 mg vitamin C, 1000 mg vitamin E and 400 µg selenium for 21 days before 131I. Plasma 8-epi-PGF2a was measured immediately before and 2 and 7 days after 131I. Results A significant increase in plasma 8-epi-PGF2a after 131I was observed in the two groups. The concentrations of 8-epi-PGF2α were significantly higher in the control group before and 2 and 7 days after 131I. The percentage of patients with elevated 8-epi-PGF2α was also significantly higher in the control group before and after 131I. Furthermore, the increase (percent) in 8-epi-PGF2α was significantly greater in the control group (average of 112.3% versus 56.3%). Only two patients (10%) reported side effects during supplementation. Conclusions Ablation with 131I causes oxidative stress which can be minimized by the use of antioxidants.

ABSTRACT

The aim of this study was to evaluate the effects of early postpartum PGF2α treatment on reproductive performance in dairy cows synchronized with targeted breeding and natural mating after voluntary waiting period. In this experiment ,120 cows were assigned to three groups irrespective of presence or absence of luteal tissue. Cows in PG- 14 group were treated with PGF2α from day 14 postpartum, cows in PG-28 group were treated with PGF2α from day 28 postpartum and cows in PG-42 group were not treated with PGF2α until the end of voluntary waiting period (d 42). After day 42 postpartum, cows in three groups were treated with PGF2α within 14-day intervals until natural mating after voluntary waiting period. Recorded reproductive parameters included days to first heat, days to first mating, days open, service per conception, conception rate, percentage of repeat breeder animals and pregnancy loss. Early PGF2α treatment from day 14 postpartum significantly decreased days to first estrus (34.9 ± 0.74, P < 0.003), days to first mating (62.35 ± 1.53, P < 0.04), days open (117.23 ± 3.1, P < 0.001) and service per conception (1.9 ± 0.09, P < 0.02); and PG-14 group presented increased conception rate (52.5%, P < 0.05). The proportion of repeat breeder syndrome tended to be affected by treatment with PGF2α from day 14 postpartum. In conclusion, treatment of cows with PGF2α from day 14 postpartum improved reproductive performance.(AU)


O objetivo do presente trabalho foi avaliar os efeitos do tratamento pós-parto precoce com PGF2α sobre o desempenho reprodutivo de vacas leiteiras sincronizadas para reprodução controlada por monta natural após o período de espera voluntário. Neste experimento, 120 vacas foram distribuídas em três grupos independentes da presença ou ausência de corpo lúteo. Vacas no grupo PG-14 foram tratadas com PGF2α a partir do 14o dia pósparto, vacas do grupo PG-28 foram tratadas com PGF2α a partir do 28o dia pós-parto e as vacas do grupo PG-42 não foram tratadas com PGF2α até o final do período de espera voluntário (d42). Após o 42o dia pós-parto as vacas dos três grupos foram tratadas com PGF2α com intervalos de 14 dias até a monta natural após o período de espera voluntário. Os registros dos parâmetros reprodutivos incluíram: dias para o primeiro estro, dias para a primeira cobertura, dias em aberto, serviços por concepção, taxa de concepção, percentagem de animais repetidores de cios e as perdas de gestações. O tratamento precoce com PGF2α, a partir do 14o dia pós-parto reduziu significativamente os dias para o primeiro estro (34,9 ± 0,74, P < 0,003), dias para a primeira cobertura (62,35 ± 1,53, P < 0,04), dias em aberto (117,23 ± 3,1, P< 0,02); e o grupo PG-14 apresentou um acréscimo na taxa de concepção (52,5%, P < 0,05). A proporção da síndrome de vacas repetidoras de cios tendeu a ser afetada pelo tratamento com PGF2α a partir do 14o dia pós-parto. A conclusão obtida foi que o tratamento das vacas com PGF2α a partir do 14o dia pós-parto melhorou o desempenho reprodutivo dos animais.(AU)

ABSTRACT

This study was to investigate whether working in conditions of elevated concentrations of mine gases (CO2, CO, CH4, DMS) and dust may result in oxidative stress. Coal miners (n=94) from the Velenje Coal mine who were arranged into control group and three groups according to a number of consecutive working days. 8-isoprostane as a biological marker of oxidative stress was measured in exhaled breath condensate (EBC). Miners who worked for three consecutive days had higher 8-isoprostane values in EBC compared to the control group.

ABSTRACT

In this study, endometrial samples were collected in 14 Nelore cows on days zero (ovulation), five, nine, thirteen and nineteen of the estrous cycle (biopsy group), and in 15 females these collections weren't performed (control group). Biopsies were done on the uterine horn endometrium contralateral to the ovary with corpus luteum. Blood samples were taken at -24, -16, -8, 0 +8, +16 and +24 hours in relation to progesterone drop (<1ng/mL, zero moment) and evaluated for 13, 14-dihydro-15-keto prostaglandin F2-alpha (PGFM) by radioimmunoassay (RIA). Plasma progesterone concentration was determined by RIA every 24 hours. Data were analyzed by ANOVA using the PROC GLM and MIXED of the SAS. The mean value for PGFM during the entire period evaluated was greater in the biopsy group. The mean concentration of PGFM at moment zero was not different between the groups; the mean concentration of PGFM was higher in the biopsy group before and after the drop in progesterone level. The maximum mean concentration observed was not different between the groups; however, the mean minimum concentration was different with high values in the biopsy group. Although the PGFM concentrations were higher in the biopsy group, the biopsy and control groups had similar length of estrous cycle showing that repeated endometrial biopsy on the side contralateral to the ovary with corpus luteum does not affect luteolysis and the length of the estrous cycle.


No presente estudo, foram coletadas amostras endometriais de 14 vacas Nelore nos dias zero (dia da ovulação), cinco, nove, 13 e 19 do ciclo estral (grupo controle), e em 15 fêmeas essas coletas não foram realizadas (grupo controle). As biópsias foram realizadas no corno uterino contralateral ao ovário contendo o corpo lúteo. Amostras plasmáticas foram coletadas nos momentos -24, -16, -8, 0 +8, +16 e +24 horas em relação à queda de progesterona (<1ng/mL, momento zero) e avaliadas quanto à concentração de 13, 14-di-hidro-15-ceto prostaglandina F2-alpha (PGFM) por radioimunoensaio (RIA). As concentrações plasmáticas de progesterona foram avaliadas a cada 24 horas também por RIA. Os dados foram analisados por ANOVA empregando-se PROC GLM e MIXED do SAS. O valor médio de PGFM durante todo o período avaliado foi maior no grupo biópsia. A concentração média de PGFM no momento zero não diferiu entre os grupos, e foi maior no grupo biópsia antes e após a queda de progesterona. A concentração máxima observada não foi diferente entre os grupos, porém a concentração mínima diferiu com maiores valores observados no grupo biópsia. Embora as concentrações de PGFM fossem maior no grupo biópsia, ambos os grupos apresentaram o mesmo comprimento do ciclo estral, demonstrando que a coleta repetitiva de biópsias endometriais no corno uterino contraletral ao ovário contendo o corpo lúteo não afeta a luteólise e o comprimento do ciclo estral.

ABSTRACT

The objective of this study was to investigate factors that influence the success of resynchronization protocols for bovines with and without progesterone supplementation. Cow synchronized and not found pregnant were randomly assigned to two resynchronization protocols: ovsynch without progesterone (P4) supplementation (n = 66) or with exogenous P4 administered from Days 0 to 7 (n = 67). Progesterone levels were measured on Days 0 and 7 of these protocols as well as 4 and 5 days post-insemination. Progesterone supplementation raised the P4 levels on Day 7 (p 3.5 had increased P/AI values while cows with BCS < 2.75 had decreased P/AI rates after P4 supplementation. Primiparous cows had higher P4 values on Day 7 than pluriparous animals (p = 0.04) and tended to have higher RRs (p = 0.06). Results of this study indicate that progesterone supplementation in resynchronization protocols has minimal effects on outcomes. Parity had an effect on the levels of circulating progesterone at initiation of the protocol, which in turn influenced the RR.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of chloroquine on airway hyperresponsiveness in asthmatic mice and explore the possible mechanism.</p><p><b>METHODS</b>Balb/c mouse models of asthma established using OVA received intraperitoneal injections of chloroquine, dexamethasone, or both prior to OVA challenge. Within 24 h after the final challenge, airway hyper- responsiveness (AHR) of the mice was assessed, and the total cell count and the counts of different cell populations in the bronchoalveolar lavage fluid (BALF) were determined under light microscopy. The severity of lung inflammation was evaluated using HE staining, and the concentrations of IL-6 and PGF2α in the BALF were detected by enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>Chloroquine pretreatment significantly decreased AHR (P<0.001) in the asthmatic mice and reduced the total cell count (P<0.01), eosinophils (P<0.001), neutrophils (P<0.01), and PGF2α levels in the BALF. Chloroquine combined with low-dose dexamethasone significantly lessened inflammations around the bronchioles (P<0.05) and blood vessels (P<0.01) in the lung tissue, and obviously lowered IL-6 (P<0.05) and PGF2α (P<0.001) in the BALF in the asthmatic mice.</p><p><b>CONCLUSION</b>Chloroquine can inhibit AHR in asthmatic mice and produce better anti-inflammatory effect when combined with dexamethasone for treatment of neutrophilic asthma.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical efficacy of acupuncture combined with auricular point sticking for menstrual headache and to discuss its mechanism.</p><p><b>METHODS</b>Eighty-five patients with menstrual headache were randomly divided into an observation group (43 cases) and a control group (42 cases). The observation group was treated with body acupuncture combined with auricular point sticking and the control group was treated with flunarizine hydrochloride capsules orally. The treatments of 3 menstrual cycles were required. The clinical efficacy was observed in the two groups. The content of serum prostaglandin F2α, (PGF2α) and plasma arginine vasopressin (AVP) in the menstrual periods of some patients randomly selected in the two groups was tested before and after treatment and was compared with that of 20 cases in a normal group. Results The total effective rate was 95.4% (41/43) in the observation group which was obviously superior to 81.0% (34/42) in the control group (P<0.01). Before treatment, the content of serum PGF2α and plasma AVP of patients in the two groups was higher than that in the normal group (all P<0.01). After treatment,the content of serum PGF2α and plasma AVP was lower than that before treatment in the two groups (P<0.01, P<0.05). The content of serum PGF2α in the observation group was decreased significantly compared with that in the control group (P<0.05) and returned to the level of the normal group.</p><p><b>CONCLUSION</b>Body acupuncture combined with auricular point sticking achieves positive efficacy for menstrual headache and its mechanism could be related to regulating the abnormal levels of serum PGF2α and plasma AVP.</p>

ABSTRACT

In 2012, the preparation process and quality standard for Guizhi Fuling capsule were improved. To compare the effects and differences of capsules before (2011) and after(2012-2014) the improvement, evaluation models for intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma were applied in rats. Models were induced by oxytocin, liqiud bacteria mixture and estrogen loading, respectively. The capsules (12 batchs/year, 48 bathcs in all), sampled randomly in 2011-2014, the effects were assessed using the three models. In anti-dysmenorrhea models, remarked reduction of writhing frequency, ET-1 and PGF2α content in uterus could be detected, as well as extension of writhing latency. In pelvic inflammation rats, depression of TNF-α and raise of IL-2 were induced by earh batch of capsules. In hysteromyoma model, uterine weight and smooth muscle proliferation, including E2 and P level in plasma, were lowered obviously by all batchs of capsules. Secondly, Guizhi Fuling capsules produced in 2012-2014 revealed better effectiveness than the ones manufactured in 2011. Moreover, pharmacodynamics indexes of the samples made in 2011 differed significantly between groups, which could not be observed in the ones ot 2012-2014. After tne preparation process and quality standard improvement, the effectiveness and homogeneity of Guizhi Fuling capsules were enhanced.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the efficacy and the reproductive endocrinal mechanism of herbal-partitioned moxibustion in the treatment of primary dysmenorrhea.</p><p><b>METHODS</b>One hundred and seventy-one cases of primary dysmenorrhea were randomized into an herbal-partitioned moxibustion group (group A), an starch-partitioned moxibustion group (group B) and an acupuncture group (group C), 57 cases in each one. In the group A, moxibustion isolated with herbal medicine was applied to Shenque (CV 8). In the group B, moxibustion isolated with starch was used at Shenque (CV 8). In the group C, acupuncture was given at Sanyinjiao (SP 6). The changes of estradiol (E2), progesterone (P) and prostaglandin levels (PGF2alpha) were observed before and after treatment, and the therapeutic effects were compared among the 3 groups.</p><p><b>RESULTS</b>The therapeutic effect in the group A was better than those in the other two groups [compared the cured rate: 89.8% (44/49) vs 60.0% (30/50), 60.4% (32/53), both P < 0.05]. In the group A, E2 level [(110.99 +/- 12.90) pg/mL vs (83.94 +/- 8.91) pg/mL, P < 0.05] and PGF2alpha level [(24.58 +/- 3.01) pg/mL vs (14.34 +/- 1.48) pg/mL, P < 0.01] were decreased and P level was increased [(4.65 +/- 0.68) ng/mL vs (6.68 +/- 0.95) pg/mL, P < 0.05]. In the group B and C, PGF2alpha level were reduced. Concerning to the regulating of E2 and PGF2alpha levels, the results in the group A were better than those in the group B and C [(-30.16 +/- 10.20) pg/mL vs (10.79 +/- 15.01) pg/mL, (22.81 +/- 12.22) pg/mL; (-13.10 +/- 2.40) pg/mL vs (-6.52 +/- 1.88) pg/mL, (-3.14 +/- 1.19) pg/mL, (see text) P < 0.05]. Concerning to the regulation of P level, the results in the group A and B were better than that in the group C (all P < 0.05).</p><p><b>CONCLUSION</b>The herbal-partitioned moxibustion achieves the significant efficacy on primary dysmenorrhea, which could be related to regulating the reproductive endocrinal level. It decreases E2 and PGF2alpha levels and increases P level.</p>

ABSTRACT

The aim of the present study was to evaluate the protective effect of catalpol on vascular endothelial function in STZ-induced type 2 diabetes mellitus (T2DM) rats. 40 high-fat diet with STZ-induced diabetes rats were randomly divided into model group, catalpol low-dose, middle-dose and high-dose group (10, 50, 100 mg x kg(-1) x d(-1)), 10 normal Wistar rats were used as the normal group. The normal and model groups were given an equivalent amount of saline. All reagents were administered by oral gavage for 6 weeks. After 6 weeks, blood glucose and lipids were detected by an automatic biochemical analyzer. The endothelium-dependent vasodilation response of thoracic aortar was detected. The pathological changes of the thoracic aorta were observed by HE staining. Ser- um nitric oxide (NO), 8-iso prostaglandin F2α (8-iso-PGF2α) and superoxide dismutase (SOD) were detected by ELISA. Reactive oxygen species (ROS) level of thoracic aorta was detected by fluorescence method. The expression of Nox4 and p22phox mRNA and protein in aortic tissue were detected by RT-PCR and Western-blot respectively. After catalpol treatment, endothelial damage of thoracic aorta was attenuated significantly; ROS level of thoracic aorta and serum level of 8-iso-PGF2α were decreased significantly; serum NO and SOD levels were remarkably elevated; expression of Nox4, p22phox mRNA and protein in thoracic aorta were significantly reduced (P < 0.05). Therefore, catalpol has protective effect on endothelial of T2DM, its mechanism may be associated with the down-regulation of Nox4 and p22phox expression, inhibiting oxidative stress reaction response.

ABSTRACT

OBJECTIVE: Postpartum hemorrhage is most common cause of maternal mortality. Active management of third stage of labor minimizes the risk of postpartum hemorrhage. To compare the effect of methylergonovine and 15-methyl prostaglandin F2alpha (15-methyl PGF2alpha) in active management of third stage of labor. METHODS: A randomized open labelled parallel study with 50 women in normal labor, 25 in each group were included. The drugs methylergonovine (0.2 mg) intravenous and 15-methyl PGF2alpha (250 microg) intramuscular were administered at the time of delivery of anterior shoulder. Main outcomes measured were amount of blood loss during the first four hours of delivery and objective measurement of hemoglobin and hematocrit levels before delivery and third day postpartum. RESULTS: There was no statistically significant difference in the blood loss between the two groups at delivery (P = 0.130), at 1 hour of delivery (P = 0.453). The blood loss with 15-methyl PGF2alpha was significantly less as compared to that of blood loss with methylergonovine at four hours of delivery (P = 0.014) and the total, i.e., during first four hours, amount of blood loss was significantly less with 15-methyl PGF2alpha (P = 0.026). There was no statistically significant difference in the hemoglobin and hematocrit levels measured predelivery and postpartum third day between both the drugs. CONCLUSION: Both the drugs were effective in controlling the amount of blood loss during the third stage of labor, 15-methyl PGF2alpha being more efficacious.
