Behavioral changes resembling human athetoid and choreiform hyperkinesias were produced b y unilateral injections of L-3,4-dihydroxyphenylalanine (l-D O P A ), dopamine, 3-m ethoxy-tyram ine and dexamphetamine into the rostromedial part of the caput caudati o f ca ts; saline, noradrenaline and 3,4 -dihydroxyphenylacetio acid were ineffective. Pretreatment with the tyrosine hydroxylase inhibitor...

The present investigation was an attempt to evaluate the effect of aflatoxin on biochemical and histopathological changes in the epididymis of mice and its possible amelioration on pre-treatment with vitamin E. Adult male albino mice were orally administered with 25 and 50 mg of aflatoxin/animal/day (750 and 1500 mg/kg body weight) for 45 days. Epididymis was isolated and processed for biochemi...

A monoclonal antibody T21 specifically recognizes the mouse epididymal sialoglycoprotein of 54,000 dalton (SGP54). The localization of SGP54 was studied in the epididymal duct of germ cell-free WBB6F1W/Wv mutant mice (W/Wv mice) by avidin biotin complex (ABC) immunohistochemistry using T21. None of the testis cells showed immunoreaction. No spermatozoa were present in the epididymal duct lumen....

Catalase activities have been evaluated in testes and caput and cauda epididymis of Wistar rats fed on zinc deficient diet for 2 and 4 weeks. The enzyme activity has been measured as chromic acetate formed by heating of dichromate (in acetic acid) in presence of H(2) O(2) with perchromic acid as an unstable intermediate. Observed non-significant increase in catalase activity in testes as well a...
