چکیده انگلیسی
Relatively little is known in relation to pathological changes of immune organs in fish when exposed to MC-LR. The ultrastructural alteration of lymphocytes was examined in the spleen and pronephros of grass carp Ctenopharyngodon idella injected experimentally with microcystin-LR. The fish were intraperitoneally injected with MC-LR at a dose of 50 µg/kg body weight, and the spleen and pronephros were dissected out at 1, 2, 7, 14 and 21 days post intraperitoneal injection (dpi). Pathological changes were then examined by transmission electron microscopy. Apoptosis was detected only in lymphocytes in the spleen, with obvious apoptotic features observed at 2 dpi; pathological changes of lymphocytes in the pronephros were also serious with mitochondria being highly edematous. However, damaged lymphocytes were almost un-observed in the spleen and pronephros at 21 dpi. These findings suggest that MC-LR can induce toxic effect on immune organs in grass carp, and the spleen may be much more sensitive to MC-LR stimulation.
