Histochemical study of the goat placentome

Abstract

The histochemical study was conducted on 18 gravid goat uteri divided into three groups according to their gestational ages as Gr I (0-50 days), Gr II (51-100 days) and Gr III (101 till term). The Perodic acid Schiff ’s (PAS), acid mucopolysaccharides (AMPs), alkaline phosphatase (ALK) and acid phosphatase (ACP), Sudan Black B and Feulgen reaction were studied. In 1st group, cryptal epithelium, intercryptal column core, trophoblast epithelium were mild postive with AMP and moderately positive for PAS. In the Caruncles; Uni and multinucleate giant cells showed mild positive with PAS, ALK and Feulgen’s reaction. Cryptal epithelium and binucleate giant cells exhibited moderate activity with PAS, AMP and Feulgen’s reaction and mild activity with ACP in 2nd and 3rd group. In the villous epithelium; uninucleate cells showed moderate activity and binucleate showed intense activity with PAS and mild activity with AMP in 2nd group. Uni and multinucleate giant cells during 3rd group showed mild activity with PAS, AMP and moderate activity with ALK and Sudan Black- B. In the arcade epithelium; Uninucleate giant cells showed mild activity and binucleate giant cells showed moderate activity in 2nd and 3rd group with PAS. Binucleate giant cells in 2nd group, uninucleate giant cells during 3rd group showed mild activity with AMP, ALK, ACP, and Sudan black B and Feulgen’s reaction.
