EFFECTS OF CIS-DIAMMINEDICHLOROPLATINUM-II (CISPLATIN) ON THE SPLENICTISSUE OF RATS - A HISTOQUANTITATIVE STUDY

Histoquantitative methods were applied to study the changes of splenic structure and proportions of splenic tissue compartments in cisplatin -treated (6 mg/kg body wt) male Wistar rats. Six days after treatment the significant reduction of volume density of white pulp was observed , which was due to the very prominent decrease of volume density of fo llicles. The volume density of periarteriolar lymphatic sheaths did no t change substantially. Volume density of the marginal zone was also s ignificantly reduced. A significant increase of volume density of conn ective tissue was observed. Morphometrical parameters of the follicles were also markedly altered: the number of follicles per mm(2) of sple en section area, the numerical density of the follicles in the spleen, and the total number of the follicles were significantly reduced.
