摘要: The arrangement and fine structure of peritubular myoid cells was studied in the testes three species reptiles (Lacerta dugesi, Testudo graeca Natrix natrix) during two short periods seasonal cycle (European spring autumn) correlated with some ultrastructural properties Leydig cells. lamina propria consists cells, fibroblasts non-cellular components comprising collageneous non-striated microfibrils. Both are arranged alternating layers surrounding seminiferous tubules. In lacertilian testis shows 1–5 which rich 50–70 A filaments exhibit plasmalemmal intracellular dense patches, smooth vesicles along cell membrane a concentration organelles juxtanuclear position. ER profiles have few lipid droplets. autumn most replaced by fibroblast-like elements. display large numbers droplets bodies, but only small amounts agranular ER. Similar changes noted Natrix. However, these boundary tissue tubules fails to show significant alterations comparing animals. both exhibits interspersed among
