The apoptotic effects of LPS are detected by various skills such as fluorescence staining, TUNEL reaction, DNA agarose gel electrophoresis, electron microscopy and fluorescence activated cell sorting. Our results demonstrated that fish lymphocytes would be apoptotic under different LPS concentrations(above 10μg/ml) and different time(above 6h) inducing, which is characterized by condensation and margination of chromatin, the formation of apoptotic bodies.

结果显示，在10μg/ml以上浓度的内毒素作用18后或以100μg/ml浓度的LPS作用6h以上，淋巴细胞即可出现明显的凋亡形态学变化，表现为染色质凝集和周边化，核断裂，形成凋亡小体，DNA发生特异降解产生典型的"梯状"电泳图谱，呈现TUNEL阳性标记等，并通过流式细胞术证实这种凋亡具有时问和剂量的依赖性。
