Improvement in post-partum uterine involution in rats treated with Apios americana / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

OBJECTIVE@#Apios americana, a plant used as a staple ingredient of native American diets, has various properties, including anti-cancer, anti-hyperglycemic, hypotensive, and anti-inflammatory activity. In Japan, Apios is used as a post-natal medication. After parturition, women undergo a period of recovery as they return to pre-pregnancy conditions. However, few health products that aid post-partum recovery are on the market. We explored whether Apios can accelerate the post-partum recovery process, in particular the involution of the uterus.@*METHODS@#Female rats kept in individual cages were mated with two male rats, with the exception of the control group (female rats without mating, on basal diet; n=6). After delivery, rats were divided into five groups based on their diet: basal diet (model; n=6); basal diet+oral intake at 5.4 g/kg of Chanfukang granules (a Chinese patent medicine preparation for post-partum lochia) (positive; n=6); basal diet containing 10% Apios powder (low; n=6); basal diet containing 20% Apios powder (medium; n=6); basal diet containing 40% Apios powder (high; n=6). Five days later, uteri and spleens were weighed. Uterus and spleen indices for each rat were calculated by dividing visceral weight by the total weight. Hormone and cytokine concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Histological analysis of uteri was completed using hematoxylin and eosin (H&E) staining. Expression of matrix metalloproteinases and inhibitors in uteri was measured by western blotting.@*RESULTS@#Our results showed that Apios treatment reduced the post-partum uterus index and regulated the hormone concentrations. Moreover, we found that the process of uterine involution was accelerated, based on morphological changes in the uterus. In addition, our results indicated that Apios alleviated the inflammatory response induced by the involution process. Transforming growth factor β was also found to be regulated by Apios. There were significant downregulation of matrix metalloproteinases and upregulation of their inhibitors by Apios, which suggested that Apios increased the rate of the collagen clearance process.@*CONCLUSIONS@#These results, based on experimental observations at the molecular and protein levels, verified our hypothesis that Apios can improve uterine involution, and demonstrated the potential application of Apios in post-partum care.

Productive and Reproductive Perfomance of Dairy Cows During Peripartum

ABSTRACT Dairy activity is of great importance for the national economy. It is also an important source of income for families in the south east region of Paraná that work in this area. There has been a notable expansion in the activities as well as in the quantity of production and the quality of the products. With this has come problems in the reproductive efficiency of the dairy cattle principally in relation to those with the greatest production. The objective of this study was to evaluate the productive profile and the reproductive efficiency of dairy cows. The evaluation covered 30 days before calving and 15, 30, 45, 60 and 90 days after the calving. The study covered cows from two properties in the Municipality of Realza-PR in Brazil. In order to do the aforementioned, we used the Body Condition Score (BCS). We evaluated the production of milk and through the use of gynecological exams and we looked at uterine involution (UI) and ovarian cyclicality. The results showed falls in the BCS in the prepartum period and in the first weeks of lactation (p<0.05) and the differences in the BCS were based on the season of the year in which the calving took place (p<0.05) with the highest BCS being noted to occur in the hot seasons. The UI correlates with the presence of corpus luteum where animals were late in their uterine involution and had delays in their first postpartum ovulation (p<0.05). The average service period and calving interval were similar to those described for dairy cattle, however, we observed variations based on the seasons of the year which was possibly related to the greater availability and quality of the forage in the hot seasons.

Results: The total effective rate in the observation (94. 0%) was higher than that in the control group(84. 0%). Compared with that in the control group, less average hemostasis time, better situation of abdominal pain, uterine involution and lower postpartum infection rate in the observation group were observed after the treatment(P<0. 05). Conclusion:Compound Yimucao oral liquid can promote the uterine involution. It’ s effective and safe in the treatment of postpartum lochirrhea.

Florfenicol associado ou não ao cloprostenol no tratamento de retenção de placenta em vacas leiteiras / Florfenicol and sodium cloprostenol for the treatment of retained placenta in dairy cows

The aim of this study was to compare the reproductive efficiency in dairy cows with retained placenta (RP), treated with Florfenicol associated or not with Cloprostenol. One hundred and eight cows with RP from dairy herds in southern Minas Gerais state and northern São Paulo state, were included for this purpose. The experiment was designed in factorial 2X2 . The four treatments encompassed two levels of each factor : 1 ) Florfenicol - 4 0mg/kg ( IM) divided in two injections or 40mg / kg ( SC) in one injection after calving; 2) Cloprostenol (0.530mg) - two injections associated with florfenicol treatment or without cloprostenol. The analysis of discrete variables used the Kruskal - Wallis (fou r groups) or Wilcoxon (two groups) statistic to compare groups. The Student "T" test was used to compare means of continuous variables. The overall occurrence of RP was 20.7%. The florfenicol groups had no effects on postpartum uterine health or subsequent reproductive efficiency of the cows. The cloprostenol injections of RP hastened the uterine involution and decreased the occurrence of uterine infection, and increased the percentage of animals with corpus luteum between 25 and 40 days after parturition. The intervals from parturition to first artificial insemination (AI) and to conception, as well as the number of AI per conception were reduced in the cloprostenol treatment.

Aspectos reprodutivos e produtivos de vacas da raça Holandesa com puerpério normal ou patológico / Reproductive and productive parameters of Holstein cows with normal or pathological puerperium

Foram avaliadas 103 vacas da raça Holandesa de primeira, segunda ou terceira ordens de lactação, com o objetivo de comparar aspectos reprodutivos e produtivos dos animais com puerpério normal ou patológico. Exames ginecológicos foram realizados semanalmente, do parto ao final do puerpério, por meio de palpação transretal, ultrassonografia e vaginoscopia. As incidências de partos gemelares, partos auxiliados, retenção de placenta e infecções uterinas até o primeiro serviço foram de 11,7%, 20,4%, 38,8% e 75%, respectivamente. A involução uterina e a primeira ovulação ocorreram aos 33,5±11,1 e 43,6±21,5 dias após o parto, respectivamente, com diferenças (P<0,001) entre vacas com ou sem infecção uterina. O primeiro serviço ocorreu aos 75,9±31,0 dias após o parto e a taxa de gestação foi de 20,7%. A produção de leite diária foi de 27,9±7,3 litros por vaca até 42 dias após o parto. O prejuízo com a redução na produtividade e o descarte do leite contaminado com resíduos de antibiótico foi equivalente a 598 litros de leite por vaca com retenção de placenta e infecção uterina. A alta incidência de transtornos puerperais interferiu na fertilidade e na produção de leite, causando elevado impacto econômico para a propriedade.

The study was performed with 103 Holstein cows of first, second or third orders of lactation, and aimed to compare reproductive and productive parameters of animals with normal or pathological puerperium. Uterine and ovarian examinations were performed weekly until 42 days after parturition, by rectal palpation, vaginoscopy and ultrasonography. The incidence of twin pregnancies, assisted births, retained placenta, and uterine infection until the first service, were 11.7%, 20.4%, 38.8% and 75%, respectively. Uterine involution and detection of the first corpus luteum occurred at 33.5±11.1 and 43.6±21.5 days after parturition, respectively, and differed (P<0.01) between cows with or without uterine infection. The first artificial insemination occurred in average at 75.9±31.0 days after parturition, and the pregnancy rate was 20.7%. Average daily milk yield was 27.9±7.3 liters/cow until 42 days after parturition. Financial losses related to decreased milk production and discarding of milk contaminated with antibiotic residues corresponded to 598 liters of milk/cow presenting retained placenta and uterine infection. The high incidence of puerperal diseases negatively affected the fertility and milk production, causing large economic impact to the milk production system.
