[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.

[Monocyte-macrophage infiltration in portions of atherosclerotic lesions of the human aorta].

Human thoracic aorta was taken from trauma victims aged from 6 to 40 years. Cell composition of the intimal layer was investigated in the lesion predisposed (LP) areas of the aorta and in the lesion resistant (LR) areas. By double immunofluorescent staining with mono and polyclonal antibodies to monocytes/macrophages (Mn/Mph) and smooth muscle cells (SMC) the presence of Mn/Mph was revealed in all aortas studied.
