Infection with hepatitis C virus (HCV) is a major cause of transfusion-associated hepatitis, cirrhosis and hepatocellular carcinoma. The present study was conducted with an objective to evaluate the prevalence of anti-HCV antibody in New Delhi, India using a large number of healthy voluntary blood donors. A total of 15,898 healthy voluntary blood donors were subjected to anti-HCV testing (using a commercially available third generation anti-HCV ELISA kit) and 249 were found to be reactive for anti-HCV antibody, yielding an overall prevalence of 1.57%. No significant difference was found between the HCV positivity rate of male (1.57%; 238/15,152) vs. female (1.47%; 11/746) donors, family (1.58%; 213/13,521) vs. altruistic (1.51%; 36/2377) donors and first-time (1.55%; 180/11,605) vs. repeat (1.61%; 69/4293) donors. The age distribution of anti-HCV reactivity showed a maximum prevalence rate of 1.8% in the age group of 20-29 years. In addition, there was a clear trend of decreasing positivity for anti-HCV with increasing age and this trend was statistically significant. The results of the present study show that the prevalence of anti-HCV antibodies in the healthy voluntary blood donors of New Delhi, India is considerably higher than the reported seroprevalence of HCV in majority of the industrialized nations and this represents a large reservoir of infection capable of inflicting significant disease burden on the society. In addition, donors of New Delhi, India showed a trend of decreasing seroprevalence with increasing age, possibly implying a higher exposure rate to HCV in younger subjects.

Estrogen and progesterone receptors were estimated in a total of 25 ovarian neoplasms. None of the benign tumors showed steroid receptors. In malignant tumors serous tumors were more often receptor positive than the mucinous. Receptor levels were correlated with the staging of the disease, menstrual status and the resectability of the tumor. The response to chemotherapeutic drugs was better in patients with low estrogen and progesterone receptors as compared to those with high levels. The latter group showed a definite response to progesterone treatment in vitro. These are the group of patients who may benefit by combination of hormones and chemotherapeutic drugs.

Summary. Treatment of ovariectomized rats with oestradiol-17\g=b\ and progesterone demonstrated that oestradiol-17\g=b\ causes secretion of sodium, potassium and water into the lumen of the uterine horn and that progesterone causes reabsorption of these substances.
