Objective: The purposes of the present study were to investigate the effect of ${\gamma}$-radiation on the expression of inhibin-${\alpha}$ proteins and genes for inhibin ${\alpha}$, ${\beta}A$, and ${\beta}B$ in the ovary. Methods: Immature mice were whole-body ${\gamma}$-irradiated with 25% of a lethal dose. At time 0, 3, 6, 12, and 24 hours after the irradiation, the ovaries were collected and used for immunohistochemistry for inhibin-${\alpha}$, and RT_PCR for inhibin-${\alpha}$, ${\beta}A$, and ${\beta}B$. Results: The expression of the immunoreactive inhibins-${\alpha}$ was maintained at 12 hours post-irradiation and reduced thereafter. The expression of inhibin-${\alpha}$ mRNA was significantly increased with the time after the irradiation. However there were no significant changes in the expression of ${\beta}A$ and ${\beta}B$ mRNAs. Conclusion: It might be thought that inhibin acts as one of the regulatory factors in the ${\gamma}$-radiation-induced follicular atresia in mice

This study was an evaluation of the significance of each parameter through aimed at pregnant women subjected to screening test(integrated test) in predicting risk of Down syndrome. We retrospectively analysed the correlation of risk of Down's syndrome with Nuchal Translucency(NT) images measured by ultrasound, Pregnancy Associated Plasma Protein A(PAPP-A), alpha-fetoprotein(AFP), unconjugated estriol(uE3), human chorionic gonadotrophin(hCG) and Inhibin A by maternal serum. As a result, a significant correlation with NT, uE3, hCG, Inhibin A is revealed with Down's syndrome risk(P<.001). In ROC analysis, AUC of Inhibin A is analysed as the biggest predictor of Down's syndrome(0.859). And the criterion for cut-off was inhibin A 1.4 MoM(sensitivity 81.8%, specificity 75.9%). In conclusion, Inhibin A was the most useful in parameters to predict Down's syndrome in the integrated test. If we make up for the weakness based on the cut-off value of parameters they will be able to be used as an independent indicator in the risk of Down's syndrome screening.

A 10-year-old Paint horse was presented with gradual changes in behavior, characterized as stallion-like including aggressiveness towards people and other horse. The abnormal right ovary was detected via transrectal ultrasonography and rectal palpation. A complete blood count and biochemical panel values were within reference ranges. The hormone analysis revealed increased testosterone 46.00 pg/mL and inhibin 0.856 ng/mL, and progesterone concentration consistent with absence of luteal tissue 1.2 ng/mL more than normal values. The purpose of the study reported was to describe a ovariectomy of enlarged ovary by using the diagonal paramedian approach. This method is useful to minimize surgical exposure and hemorrhage. This ovary was confirmed fibroma by histological examination post operation. Behavior problems and the hormone values were alleviated after surgery, and clinical signs of complication were not showed.
