The irradiation effect of (60)Co at the three dose level of 3 mGy, 30 mGy and 300 mGy on the histology of liver of the freshwater fish Oreochromis mossambicus was investigated. The liver of O. mossambicus was dissected out and processed for light microscopy studies. (60)Co exposed O. mossambicus were found to result in several alterations in the histoarchitecture of liver. The alterations included mild congestion of blood vessels, structural alteration, cellular swelling, vacuolation and necrotic liver cells, indicating a definite response to (60)Co irradiation. The results suggest that the liver of O. mossambicus exposed to (60)Co were structurally altered with increasing dose levels. It is to record that alteration in the liver does not affect the physiology, behaviour or lethality of the individuals. Self regulating mechanisms would have influenced the liver to remain sustained. To confirm the same further studies in the direction by increasing dose level is required.
研究了（60）Co 在 3 mGy、30 mGy 和 300 mGy 三个剂量水平对淡水鱼奥利亚罗非鱼肝脏组织学的辐照效应。取出奥利亚罗非鱼的肝脏并进行光学显微镜研究。（60）Co 暴露的奥利亚罗非鱼肝脏结构发生了多种改变。这些改变包括血管轻度充血、结构改变、细胞肿胀、空泡化和坏死的肝细胞，表明对（60）Co 辐照有明确的反应。结果表明，随着剂量水平的增加，奥利亚罗非鱼的肝脏结构发生了改变。需要记录的是，肝脏的改变不会影响个体的生理、行为或致死率。自我调节机制会影响肝脏保持持续状态。为了进一步证实这一点，需要在增加剂量水平的方向上进行更多的研究。
