Changes in Enzymatic Constitution in Zinc-deficient
The necessity of a metal ion for the activity or synthesis of specific enzymes may be revealed by growing the organism under conditions of the metal deficiency and comparing its enzyme systems with those of normal tissue. Waring and Werkman (1) reported that iron deficiency in Aerobatter indologenes resulted in the suppression of a number of enzymes. Zinc deficiency results in increased acid pr...
متن کاملThe Morphological Changes of Adult Mouse Testes after 60Co γ-Radiation
Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...
متن کاملControl of luteinizing hormone in postpubertal boars with large testes.
The objective of the present study was to investigate endocrine control of LH in postpubertal boars with large testes. Eight boars with the highest estimated paired testis weights from a line selected for large testes and nine boars from a line selected at random were used. Blood samples were collected over a 13-h period at weekly intervals for 4 wk. Samples were collected at 12-min intervals f...
متن کاملCatalase in Testes and Epididymidis of Wistar Rats Fed Zinc Deficient Diet
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...
متن کاملZinc modulates heat-induced degenerative effects in mice testes
This study was designed to investigate whether administration of zinc sulphate could improve theresponse of mouse testis to degenerative effects of short term exposure heating. Fifty-four adult male Balb/Cmice were anaesthetized and the scrotums of 36 of them were immersed for 15 min in a waterbath at 43°C.Immediately after the heating, half of the heated animals (n = 18) were injected with sal...
