Effect of hamycin on prostatatic secretion and serum testosterone levels in the rat

Effect of hamycin on prostatatic secretion and serum testosterone levels in the rat. Naik, S. R. (Res. Cent., Hindustan Antibiot. Ltd., Poona City 411 018, India). Hind. Antibiot. Bull., 25(3-4), 125-30 (English) 1983. CODEN: HINAAU. ISSN: 0018-1935. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 2 Hamycin (I) [1403-71-0] (25 mg/kg, orally for 4 wk) treatment in rabbits decreased prostatic wt. and fluid secretion. The decrease in prostate secretion was completely reversed by administration of testosterone propionate [57-85-2]. Addnl., serum testosterone [58-22-0] levels of chronically I-treated were markedly lower than controls. Decreased cholesterol [57-88-5] levels were also obsd. after 4 wk of I treatment.

Effect of the prophylactic administration of vitamins A and E to piglets fed with complete mixtures

Effect of the prophylactic administration of vitamins A and E to piglets fed with complete mixtures. Dvorak, Miroslav (Vyzk. Ustav Vet. Lek., Brno 621 32, Czech.). Vet. Med. (Prague), 28(11), 641-50 (Czech) 1983. CODEN: VTMDAR. ISSN: 0375-8427. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) An i.m. injection on the day 1-3 of age of Axerophthol (retinol in oil) [68-26-8] at 25,000 IU retinyl acetate plus Agovirin (testosterone propionate) [57-85-2] did not affect the growth of piglets. The plasma and liver vitamin A [11103-57-4] were only slightly increased at weaning at an age of 4 wk and 3 wk after weaning. An i.m. injection of Axerophthol + 300 mg Erevit (tocopheryl acetate) [58-95-7] at weaning did not have a pos. effect on growth or health. Vitamin A increased in the liver but not in circulation, and the decrease in tocopherolemia, caused by reduced feed intake after weaning, was not prevented. Oral administration of 1 mL Axetocal (30 mg retinol + 30 mg tocopheryl acetate + 100,000 IU ergocalciferol/1 mL oil) [51910-58-8]/pig at an age of 53 days raised the plasma vitamin E [1406-18-4] and the liver and plasma vitamin A more than did an i.m. injection. The preventive injections of vitamin A and E to piglets did not increase the economic profits when the sows and piglets were fed with the current complete mixts. The problems of supplying vitamin E to weaned piglets are discussed.
