RESUMO

This case study aims to measure the level of acceptance of violence among women and couples and to reveal the level of acceptance within and outside the families of women who have participated in working life. The concepts of anger and violence, physical, sexual, psychological, emotional, and economic violence, which are the sub-components of violence, violence in dating, and marital relations are examined separately according to Feminism and Social Learning Theory approaches. The Working Group was formed by applying questionnaires to 50 participants from the cities of Kyrenia, Güzelyurt, Lefke, Nicosia, and Magusa and determining the 20 participants with the highest level of acceptance of violence. The 11 people who agreed to the study were interviewed for a Dec of 1 week and 5 sessions ranging from 20 to 30 min. It is observed that women who are subjected to violence have a deep sense of helplessness and accept their helplessness, as well as those women resort to various passive solutions, such as silence and avoiding attitudes that make their partner angrier. The sense of helplessness, as a result of chronic depression, makes it inevitable to experience suicide cases. This study will be particularly important in terms of revealing the levels of domestic and non-family violence exposure and acceptance of violence by women who have participated in working life.

RESUMO

Abstract Introduction: As a supplement, beta-glucan has various therapeutic healing effects generated by the immune cells. It has been scientifically approved and proven to be a biological defense modifier. The aim of this study was to investigate the effects of beta-glucan on treatments administered in an acute otitis media model Objectives: This study investigated the effect of beta-glucan on the treatment of acute otitis media in an acute otitis media -induced animal model. Efficacy was evaluated both immunologically and histologically. Methods: The study sample comprised 35 adult rats, randomly separated into 5 groups of 7: Group 1 (control), Group 2 (acute otitis media, no treatment), Group 3 (acute otitis media + antibiotic), Group 4 (acute otitis media + beta-glucan) and Group 5 (acute otitis media + beta-glucan + antibiotic). Analyses were made of the histopathology and immunology examination results in respect of thickening of the tympanic membrane, epithelium damage, inflammation, and sclerosis. In all groups the serum levels of TNF-α, IL-4, IL-6 and IL-1β were evaluated. Results: All serum cytokine levels were significantly lower in the beta-glucan and antibiotictreated groups compared to the acute otitis media Group. Significant differences in tympanic membrane thickness, inflammation, epithelium damage, and sclerosis values were observed between the acute otitis media + antibiotic and acute otitis media + beta-glucan Groups. According to these parameters, the values in aute otitis media + antibiotic + beta-glucan Group were markedly lower than those of the other groups. There was a significant difference in the acute otitis media + antibiotic + beta-glucan Groups compared to acute otitis media Group (p < 0.001). Conclusions: Both antibiotic and beta-glucan treatment reduced acute otitis media signs of inflammations in an acute otitis media-induced rat model, decreasing histological damage and cytokine levels. Co-administration of antibiotic and beta-glucan led to a significant reduction in tympanic membrane thickness, inflammation, and epithelium damage. Antibiotic + beta-glucan treatment resulted in a greater decrease in tympanic membrane thickness, inflammation, and epithelium damage than in the other groups. From these results, it can be suggested that beta-glucan, in combination with antibiotics may provide an alternative for the treatment of acute otitis media.


Resumo Introdução: Como suplemento, o beta-glucano apresenta vários efeitos terapêuticos gerados pelas células imunológicas. Cientificamente aprovado, mostrou ser um modificador de defesa biológica. Objetivo: Investigar os efeitos do beta-glucano nos tratamentos administrados em um modelo de otite média aguda induzida em um modeloanimal. A eficácia foi avaliada imunológica e histologicamente. Método: A amostra do estudo foi composta por 35 ratos adultos, divididos aleatoriamente em 5 grupos de 7: grupo 1 (controle), grupo 2 (otite média aguda, sem tratamento), grupo 3 (otite média aguda + antibiótico), grupo 4 (otite média aguda + beta-glucano) e grupo 5 (otite média aguda + beta-glucano + antibiótico). Foram feitas análises dos resultados dos exames histopatológicos e imunológicos em relação ao espessamento da membrana timpânica, dano ao epitélio, inflamação e esclerose. Os níveis séricos de TNF-α, IL-4, IL-6 e IL-β foram avaliados em todos os grupos. Resultados: Todos os níveis séricos de citocinas foram significativamente mais baixos nos grupos tratados com beta-glucano e antibióticos em comparação com o grupo otite média aguda. Diferenças significativas na espessura da membrana timpânica, inflamação, dano do epitélio e esclerose foram observadas entre os grupos otite média aguda + antibiótico e otite média aguda + beta-glucano. De acordo com esses parâmetros, os valores no grupo otite média aguda + antibiótico + beta-glucano foram acentuadamente inferiores aos dos demais grupos. Houve uma diferença significante no grupo otite média aguda + antibiótico + beta-glucano em comparação ao grupo otite média aguda (p < 0,001). Conclusão: Ambos os tratamentos com antibiótico e com beta-glucano reduziram os sinais de inflamação da otite média aguda em um modelo de rato com otite média aguda induzida, diminuíram os danos histológicos e os níveis de citocinas. A administração concomitante de antibiótico e beta-glucano levou a uma redução significativa na espessura da membrana timpânica, inflamação e danos ao epitélio. O tratamento com antibióticos + beta-glucano resultou em maior diminuição na espessura da membrana timpânica, inflamação e danos no epitélio do que nos outros grupos. A partir desses resultados, pode-se sugerir que o beta-glucano, em combinação com antibióticos, pode fornecer uma opção para o tratamento da otite média aguda.

RESUMO

The aim of this study was to investigate the potential beneficial effects of ß-glucan treatment against oxidative, histological and spermatological damage caused by cisplatin on the male reproductive system. Twenty-eight Sprague Dawley male rats were used in the study. The rats were randomly divided into four equal-sized groups: a control group, cisplatin group (7 mg/kg in a single-dose cisplatin administered intraperitoneally), ß-glucan group (ß-glucan given at a dose of 50 mg kg-1  d-1 for 14 day) and a cisplatin plus ß-glucan group (cisplatin and ß-glucan administered together at the same dose). Cisplatin administration induced an increase in the level of thiobarbituric acid-reactive substances, a lipid peroxidation indicator. It induced a decrease in enzymatic (superoxide dismutase, catalase and glutathione peroxidase) activities and nonenzymatic (reduced glutathione) antioxidant levels. In addition, cisplatin caused both histological and spermatological damage, as shown by a decrease in sperm motility and epididymal sperm concentrations and an increase in abnormal sperm rates. The ß-glucan treatment improved cisplatin-induced oxidative, histological and spermatological damage. This study revealed that ß-glucan treatment provided prevention against male reproductive system damage caused by cisplatin. These preventative effects were likely due to its antioxidant properties.

RESUMO

OBJECTIVES: In this experimental study, the effect of hesperidin on the treatment of acute otitis media (AOM) was investigated in an AOM-induced rat model. METHODS: In total, 35 rats were randomly divided into the following five groups (n=7): group 1 (control), group 2 (AOM with no treatment), group 3 (AOM+antibiotic), group 4 (AOM+hesperidin), and group 5 (AOM+hesperidin+antibiotic). On day 14, group 3,4 and 5 rats were given antibiotic and hesperidin via gavages, respectively. Histopathological and immunological analyses were performed and the results analyzed. RESULTS: Serum levels of TNF-α, IL-4, IL-6 and IL-1ß were significantly decreased in the hesperidin- and antibiotic-treated groups compared to the AOM group. The AOM+antibiotic and AOM+hesperidin groups demonstrated reduced histological damage compared to the AOM group. Between the AOM+antibiotic and AOM+hesperidin groups, significant differences in tympanic membrane thickness(ThicTM), inflammation(Inf), and sclerosis(Sc) values were observed. However, no difference in epithelial damage(DamEpith), was seen between the two groups. There was a significant difference in the AOM+antibiotic and AOM+antibiotic+hesperidin groups compared to AOM group (P<0.001). CONCLUSIONS: In this study, we observed that both antibiotic and hesperidin treatment reduced AOM symptoms in an AOM-induced rat model. The values in AOM+antibiotic+hesperidin group were markedly lower than those of the other groups. From our results, we propose that hesperidin, in combination with antibiotics, may provide a successful alternative treatment for AOM compared with antibiotics used alone.

RESUMO

PURPOSE: To evaluate the impact of systemic cyclophosphamide treatment on the rat uterus and investigate the potential therapeutic effects of natural antioxidant preparations curcumin and capsaicin against cyclophosphamide side effects. METHODS: A 40 healthy adult female Wistar albino rats were used in this study. Rats were randomly divided into four groups to determine the effects of curcumin and capsaicin against Cyclophosphamide side effects on the uterus (n=10 in each group); Group 1 was the control group (sham-operated), Group 2 was the cyclophosphamide group, Group 3 was the cyclophosphamide + curcumin (100mg/kg) group, and Group 4 was the cyclophosphamide + capsaicin (0.5 mg/kg) group. RESULTS: Increased tissue oxidative stress and histological damage in the rat uterus were demonstrated due to the treatment of systemic cyclophosphamide chemotherapy alone. The level of tissue oxidant and antioxidant markers and histopathological changes were improved by the treatment of curcumin and capsaicin. CONCLUSION: Cytotoxic effects of natural alkylating chemotherapeutic agents like cyclophosphamide on the uterus can be prevented by curcumin and capsaicin.

RESUMO

OBJECTIVE: To evaluate the protective effects of glycyrrhetinic acid (GA) and chrysin (CH) on experimental ischemia-reperfusion (I/R) injury in rat ovaries using tissue oxidative stress marker levels, hormone levels, and histopathological scores. METHODS: Sixty healthy rats were randomly divided into six equal groups: control, I/R, I/R + CH (50 mg/kg/day), I/R + GA (100 mg/kg/day), CH (50 mg/kg/day), and GA (100 mg/kg/day). Biochemical, hormonal, and histopathological evaluations were performed on blood and tissue samples 14 days after CH and GA treatment. RESULTS: The antioxidant defense system parameters were significantly higher in the ovarian tissues of the I/R + CH and I/R + GA groups than in those of the I/R group. Serum follicle-stimulating hormone levels were significantly reduced, and serum anti-Müllerian hormone levels were significantly increased in rats treated with CH and GA compared with those in the I/R group. Additionally, the histopathological scores of the I/R + CH and I/R + GA groups were significantly improved compared with those of the I/R group. CONCLUSIONS: The significant improvements in tissue oxidative stress parameters, serum hormone levels, and histological scores observed in this study indicate that treatment with CH or GA may be a conservative approach to prevent I/R injury in adnexal torsion cases after the ovarian detorsion procedure.

RESUMO

The objective of this article is to analyze the effects of nerolidol and hesperidin treatment on surgically induced endometriosis in a rat model. Endometriosis was induced in 24 healthy adult female Wistar albino rats via homologous uterine horn transplantation. Three operations were performed on each rat. After the second operation, the rats were randomized into control, nerolidol, and hesperidin treatment groups, and medications were administered for 2 weeks. The effects of the drugs on the endometriotic foci were evaluated after the third operation. Compared with the endometriosis control group, the average volume of the lesions was significantly lower in rats treated with hesperidin and nerolidol. Malondialdehyde levels were significantly reduced in the nerolidol-treated group, and glutathione levels and superoxide dismutase activity were significantly elevated in the endometriotic foci of both the hesperidin- and nerolidol-treated groups compared with the endometriosis group. Hesperidin and nerolidol treatment also improved histological parameters, such as hemorrhage, vascular congestion, necrosis, and inflammatory cell infiltration in the endometriotic foci. The results of this study demonstrated that treatment with the potent antioxidants nerolidol and hesperidin caused a significant regression of surgically induced endometriotic foci in rats.

RESUMO

BACKGROUND: In recent years, cancer rates have been rising among reproductive-age women. Thus, chemotherapy exposure has become an important cause of premature ovarian failure (POF). There has been growing interest regarding the preservation and restoration of ovarian function before and after oncological treatment because of the reproductive risk of chemotherapeutics and improved long-term survival of cancer patients. In this study, we sought to analyze the effects of curcumin (CRC) and capsaicin (CPS) on cyclophosphamide-induced POF in a rat model. METHODS: POF in rats was induced by intraperitoneal injection of 200 mg/kg cyclophosphamide on day 1 and then 8 mg/kg/day for the following 14 days. After 14 days of cyclophosphamide administration, rats were randomly divided into three groups as follows (n = 10/group): POF, POF + CRC (100 mg/kg/day), and POF + CPS (0.5 mg/kg/day) to determine the effects of CRC and CPS on the cyclophosphamide-induced POF rat model. Biochemical, hormonal, and histopathological evaluations were performed on blood and tissue samples 14 days after the CRC and CPS treatments. RESULTS: Malonaldehyde levels were significantly reduced, and glutathione levels and superoxide dismutase activity were significantly increased, in ovarian tissues in the POF + CRC and POF + CPS groups compared with the POF group. In the POF group, we observed hemorrhage and prominent mononuclear cell infiltration beneath the germinative epithelium, vascular congestion in ovarian stroma, hemorrhage around the corpus luteum, and atresia in ovarian follicles. This histopathological damage was significantly improved by treatment with CRC and CPS. There was a significant reduction in serum follicle-stimulating hormone and luteinizing hormone levels in rats treated with CRC and CPS compared with the POF group. Moreover, the levels of estradiol and anti-mullerian hormone in rats treated with CRC and CPS were significantly increased compared with the control group. CONCLUSIONS: In conclusion, CRC and CPS treatment of rats with cyclophosphamide-induced POF had a beneficial effect on reducing ovarian damage by improving tissue oxidative stress marker levels, ovarian reserve marker levels, and histopathological parameters. The significant improvements in ovarian tissue histopathological damage and hormonal levels detected in this study indicate that treatment with CRC or CPS might be a conservative treatment approach for cyclophosphamide-induced POF.

RESUMO

AIM: The aim of this study was to determine the effects of obesity on amniotic fluid (AF) inflammatory markers in second-trimester AF, testing the hypothesis that there is a relationship between maternal body mass index (BMI) and fetal inflammatory exposure. METHODS: AF was obtained from 84 singleton pregnant women undergoing elective amniocentesis for karyotype analysis at 16-24 weeks of gestation between April 2014 and May 2016. The cell-free AF was used to analyze interleukin (IL)-1ß and IL-6, and matrix metalloproteinase (MMP)-1, MMP-6, and MMP-13. RESULTS: IL-1ß levels were significantly higher in class II-III obese patients than in class I obese, overweight, and normal weight patients (14.68 ± 1.37 vs. 13.34 ± 1.86 vs. 13.00 ± 2.22 vs. 10.78 ± 1.92, respectively; p < 0.05). IL-6 levels were lowest in the normal weight group and highest in class II-III obese patients. MMP-1, MMP-6, and MMP-13 levels were also significantly higher in class II-III obese patients than in the other groups. CONCLUSION: This study demonstrated that the fetuses of class II-III obese women are exposed in utero to higher cytokine and MMP levels than fetuses of lean women. Modification of current cutoff levels of intra-amniotic cytokines and MMPs according to the BMI could improve the accuracy of the prenatal diagnosis of intra-amniotic infection and inflammation.

RESUMO

PURPOSE: To determine the toxic effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on reproductive system and the beneficial effects of Montelukast (ML) with histological and biochemical analysis. METHODS: Rats were randomly divided into four equal groups (control, TCDD, ML and TCDD+ML). Tissue samples were collected on day 60 and oxidative status and histological alterations were analyzed. RESULTS: The results showed a significant increase in oxidative and histological damage on uterine and ovarian tissues. Otherwise, the oxidative and histological damages caused by TCDD were prevented with ML treatment. CONCLUSION: The toxic effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on female reproductive system were reversed with Montelukast treatment. Therefore, we claimed that ML treatment might be useful for TCDD toxicity.

RESUMO

PURPOSE: To investigate the protective effect of Bg on cisplatin (CP)-induced neurotoxicity in rats. METHODS: Twenty eight rats were randomly distributed into four groups. The first group was kept as a control. In the second group, CP was given at the single dose of 7 mg/kg intraperitoneally. In the third group, ßg was orally administered at the dose of 50 mg/kg/day for 14 days. In the fourth group, CP and ßg were given together at the same doses. RESULTS: CP treatment caused significant oxidative damage via induction of lipid peroxidation and reductions antioxidant defense system potency in the brain tissue. In addition, histopathological damage increased with CP treatment. On the other hand, ßg treatment largely prevented oxidative and histopathological negative effects of CP. CONCLUSIONS: Cisplatin has severe neurotoxic effects in rats and ßg supplementation has significant beneficial effects against CP toxicity depending on its antioxidant properties. Thus, it appears that ßg might be useful against CP toxicity in patients with cancer in terms of nervous system.

RESUMO

The aim of this study was determined the effects of Hesperidin (HP) on neuronal damage in brain tissue caused by Experimental allergic encephalomyelitis (EAE), an established model of multiple sclerosis in C57BL/J6 mice. To explore 40 mice were equally divided into four groups: (1) Control, (2) EAE, (3) HP, and (4) HP + EAE. 14 days after induction of EAE with MOG35-55 and pertussis toxin, the mice treated with HP at the doses of 50 mg/kg/day for 7 days subcutaneously. To our results HP treatment prevents the oxidative stress caused by EAE via a decrease in lipid peroxidations and increase in elements of the antioxidant defense systems in brain tissue. Also, EAE elevate the IL-17, express the pro-inflammatory cytokines, and caspase-3-like immunreactivity, show apoptosis, staining in EAE mice brain and increased the incidence of histopathological damage. However, immonohistochemical and histological changes were reversed with HP. Moreover, elevated TNF-α and IL-1ß levels, a result of EAE, were decreased in serum and neurological deficits as clinical signs were reversed with HP treatment in EAE mice, given HP. In conclusion, HP treatment effectively prevents oxidative, immunological and histological damage in the brain caused by EAE. It was thought that the beneficial effects of HP are likely a result of its strong antioxidant and anti-inflammatory properties.

RESUMO

Hepatocellular carcinoma is one of the most prevalent cancers, with a high morbidity rate, even in developed countries. In the present study, the curative effect of the Schiff base (SB) heterodinuclear copper(II)Mn(II) complex on diethylnitrosamine (DEN)-induced liver carcinoma was investigated. Hepatocarcinoma was initiated by an injection of DEN and promoted by phenobarbital (0.05%) in the diet. In addition, the potential nephrotoxicity of SB was evaluated in a cisplatin-induced nephrotoxicity model. Rats were administered the SB complex (1 and 2 mg/kg body weight/day) for 24 weeks, and cancer progression was investigated by macroscopic, histopathological, and western blot examinations. The administration of SB decreased the incidence and the number of hepatic nodules in a dose-dependent manner by regulating inflammation response and the apoptotic pathway. Western blot analyses from the livers of rats treated with SB after DEN induction showed significantly enhanced Bax and caspase-3 levels, with a marked decrease in the levels of Bcl-2, NF-κB p65 and cyclooxygenase (COX)-2. Results from the nephrotoxicity study showed that, whereas cisplatin increased serum urea nitrogen and creatinine levels, no increase in serum biochemical parameters was detected in SB-treated animals. Moreover, protein levels of NF-E2-related factor-2 (Nrf2) and heme oxygenase-1 were lower, whereas nuclear factor-κB (NF-κB p65) and activator protein-1 levels were higher in the kidneys of cisplatin-treated animals compared with that of the SB groups. Therefore, the SB complex could be an alternative chemotherapeutic option for liver cancer treatment once its safety in clinical applications has been examined.

RESUMO

This study investigated the effects of 18ß-glycyrrhetinic acid (GA) on neuronal damage in brain tissue caused by global cerebral ischemia/reperfusion (I/R) in C57BL/J6 mice. All subjects (n = 40) were equally divided into four groups: (1) sham-operated (SH), (2) I/R, (3) GA, and (4) GA+I/R. The SH group was used as a control. In the I/R group, the bilateral carotid arteries were clipped for 15 min, and the mice were treated with the vehicle for 10 days. In the GA group, mice were given GA (100 mg/kg) for 10 days following a median incision without carotid occlusion. In the GA+I/R group, the I/R model was applied to the mice exactly as in the I/R group, and they were then treated with the same dose of GA for 10 days. Cerebral I/R significantly induced oxidative stress via an increase in lipid peroxidaitons and a decrease in elements of the antioxidant defense systems. However, GA treatment was protective against the oxidative effects of I/R by inducing significant increases in antioxidant defense systems and a significant decrease of lipid peroxidations. Additionally, cerebral I/R increased the incidence of histopathological damage and apoptosis in brain tissue, but these neurodegenerative effects were eliminated by GA treatment. Therefore, the current study demonstrated that GA treatment effectively prevents oxidative and histological damage in the brain caused by global I/R. In this context, GA may be useful for the attenuation of the negative effects of global cerebral I/R and, in the future, it may be a viable and safe alternative treatment for ischemic stroke in humans.

RESUMO

The objective of the current study was to investigate the protective effects of hesperidin against oxidative stress, altered cytokines levels and histological changes in rats induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Rats were divided randomly into four equal groups (Control, TCDD, hesperidin and TCDD+hesperidin). TCDD and hesperidin were given by gavage, dissolved in corn oil at doses of 2 µ/kg/week and 50 mg/kg/day respectively. The blood and tissue samples were taken from all rats on the 60(th) day, to be analyzed for the determination of oxidative stress, histological changes and cytokine levels. The results indicated that hesperidin prevented oxidative damage caused by TCDD via decrease lipid peroxidation and increased antioxidant defense systems. It also reversed the histological damage induced by TCDD. Although, TCDD led to a significant increase in TNF-α and IL-1ß levels, hesperidin treatment was able to normalize these values in rats. In conclusion, it was shown that TCDD caused adverse effects as regards cytokine levels, histological alterations and oxidative stress in rats. However, hesperidin treatment mitigated these toxic effects. These results suggest that hesperidin could play a protective role against TCDD toxicity.
