THE EFFECT OF EPINEPHRINE AND COMPETITION BETWEEN MALES ON THE IN VITRO METABOLISM OF RABBIT TESTIS

Publication: Canadian Journal of Physiology and Pharmacology
July 1964

Abstract

An investigation was conducted to test the effect of stress for periods of 3, 5, and 10 days on metabolic activity in vitro, testis weight and morphology and protein, ribonucleic acid (RNA), deoxyribonucleic, acid (DNA) and cholesterol content of the testis. The two stressors (epinephrine injection and competition between males) caused an increased oxygen uptake in vitro in both testis and kidney cortex slices. This was associated with decreased glucose uptake and no change in lactic acid production in both tissues. There was no significant change in protein, RNA, DNA, and cholesterol content of testis due to stress within the 10 day period. Also, the stressors did not alter significantly testis weight, percent dry matter, or morphology. These data indicate that stress for 10 days does not have any significant effect on testis morphology and size but does cause significant alterations in metabolic activity of testis and kidney cortex slices.
