[Effect of hyperprolactinemia of varying origin on paracrine relationships in rat testes].

Light microscopy characteristics of mature rat testes were studied in control and hyperprolactinemia rats. The number of cells defined as granulocytes in interstitial regions adjacent to seminal ducts at stage VII and XII of spermatogenesis has been calculated. Normal deference difference between these parameters diminish in hyperprolactinemia.

[Effect of gene db dose on the development of beta-cytotropic and immunotropic effects of long-term glibenclamide administration in C57BL/KsJY mice].

The studies have revealed a modifying influence of gene db on the expressivity of damaging beta-cytotropic effect of long-term sulphanilamide therapy and on the development of autoimmune cell response to antigens of pancreatic islets. It is substantiated as promising to study a significance of individual genes and their doses in determining the variations of reactivity to beta-cytotropic and immunotropic effects of the chemical nature factors.
