HISTOPATHOLOGICAL CHANGES IN THE GILL, LIVER AND INTESTINE OF HETEROPNEUSTES FOSSILJS (BLOCH) TREATED WITH ACACIA AURICULAEFORMIS (A. CUNN. EX BENTH.) AND MESUA FERREA (LINN.) PLANT PARTS

摘要

Histopathological changes in the gill, liver and intestine of Heteropneustes fosstiis were observed after 24 hours exposure to 50% ethyl alcohol of Acacia auriculaefbrmis and Mesua ferrea plant parts. Main changes in the gills included distorted gillarches, disorganized gill lamellae, demolished gill filaments and coalesced interbranchial septum. Changes in the liver included compactly or loosely arranged hepatic cells, damaged and reduced central vein, blood clotted portal vein, reduced or swollenhepatic artery and degenerated blood sinusoids. In the intestine proliferated mucosa, swollen and shrunken muscularis, disintegrated submucosa, vacuolated and deshaped villi were observed. Extent of damage was greater with M. ferrea than that of A. awiculaeformis plant parts.
