[Effect of tocopherol and protein deficiency on the activity of enzymes and their isoenzymatic spectra in rat testes].
The symptoms of E-avitaminosis against protein deficiency in the ration become manifest much earlier, i. e. in 12--16 weeks of the experiment instead of 24--36 weeks with the primary-deficient ration. This was marked by the development of the creatinuria, the falling blood serum and testes tissue tocopherol, a higher peroxidized erythrocytes hemolysis, the animals demonstrating a disturbed generative function. In the testes of the E-avitaminotic rats an appreaciably increased total activity of glucose-6-phosphate-dehydrogenase (G-6-PDG) and of the acid phosphatase (AP) was demonstrated, whereas the LDG remained essentially unchanged. An investigation of their isoenzymatic spectra revealed a considerable activity of the basic 5 G-6-PDG fractions with the appearance of additional ones, along with the disappearance of the specific LDG fraction--X-2 and a drastic fall in the activity of the specific fraction for the testes--LDG-X-1, with concurrent rise in the activity of the 5 basic fractions. In the isoenzymatic AP spectrum disappeared the AP-3 fraction of the degenerating testes tissues and a redistribution of the activity between the fractions took place.
