[Biochemical aspects of testicular degeneration in the vitamin A deficient rat. 4. Permeability of the vascular walls].
Vitamin A deficiency modifies Na and K concentration values in oedematous testes. On one hand there is an increase of Na, on the other hand a decrease of K. Subcellular protein concentrations are impaired. Testicular fluid electrophoresis show it gets from plasma or lymph. No significant influence of ATPase (Na,+ K+) was demonstrable. Stimulation of lysosomal beta-glucuronidase can explain this fluid accumulation.
