Experience with a measles vaccine manufactured in India.

Five hundred and twenty seven children between 7 months and 2 years of age were vaccinated with measles vaccine manufactured by the Serum Institute of India. The sero-conversion rate in children who had no antibodies previous to vaccination was 98.4% as tested in HI. Ninety per cent of children who had pre-vaccination measles antibodies showed a two-fold or more rise in HI antibodies. The side reactions of the vaccine were negligible.

Biosynthesis and localization of inhibin in human prostate.

Inhibin biosynthesis by human prostatic tissue was investigated in vitro. Serum levels of inhibin as well as tissue concentrations in different cells and zones of the normal and benign hyperplastic prostates were determined. Immunocytochemical localization of inhibin identified the involvement of epithelial but not stromal cells in the synthesis and release of prostatic inhibin into the circulation. The endocrine and paracrine functions of prostatic inhibin remain to be elucidated.

Circulating levels of inhibin, prolactin, TSH, LH, and FSH in benign prostatic hypertrophy before and after tumor resection.

Using specific radioimmunoassays, serum prolactin, TSH, LH, FSH, and inhibin levels were estimated in normal subjects and in patients with benign prostatic hyperplasia (BPH) before and after tumor resection. In the case of BPH, there was a significant rise in inhibin levels as compared to age-matched control groups, whereas LH and FSH levels were decreased significantly. The levels of inhibin and prolactin were significantly reduced after surgery, but no consistent changes in LH, FSH, or TSH levels were noted. The changes observed in hormonal levels in the BPH patients were not related to patient's age or size of the tumor.

Binding characteristics of inhibin in rat ventral prostate.

Homogeneous preparation of human seminal plasma inhibin (molecular weight 13,500) was iodinated with 125I to a specific activity of about 40-45 microCi/micrograms and tested for binding to a rat prostate crude membrane preparation. The binding of inhibin was a saturable process as well as time and temperature dependent. This binding was displaceable in a dose-dependent manner by unlabelled inhibin. Other hormones such as LH, FSH, Prl, and TSH from rat or human origin did not influence the binding of labelled inhibin to rat prostate membrane. Of various age groups of rats studied, the maximum binding was observed in 75-day-old rats. The radiolabelled inhibin also showed specific binding to rat pituitary. The preliminary studies regarding involvement of steroids in the control of inhibin receptors in prostate and pituitary indicated that testosterone activates the inhibin receptors at the prostatic level whereas estradiol did not have any effect. However, estradiol increases the pituitary receptors for inhibin as compared to testosterone.

Activin Receptors

Aspirin in acute gastroenteritis: a clinical and microbiological study.

Soluble aspirin given by mouth in divided dosage decreased intestinal fluid loss in infants and young children with acute gastroenteritis. The treated group had significantly less diarrhea, which ceased earlier and needed less intravenous therapy, than a randomly selected control group given an indistinguishable placebo. This effect of aspirin occurred with diarrhea caused by Salmonella, Aeromonas, Escherichia coli producing heat-labile toxin, and rotavirus, but not with diarrhea associated with strains of E. coli producing heat-stable toxin.
