Alteration Of Ultrastructre In Cyprinus Carpio Hepatocytes From Exposure To Temperature And Copper

The fish liver is an organ central to numerous vital functions in metabolism. It is a majorsite of accumulation, biotransformation and excretion of xenobiotics and responds sensitivelyto environmental contamination. Thus, the liver has been considered as a primary target organof toxic chemicals. It is commonly realized that any physiological and biochemical responses,if severe enough, will eventually result in morphological alterations or structuralmodifications followed by functional changes. In morphological studies, histopathologicalalterations are importantindicators of the effects of environmental pollution on organisms. Especially in mitochondriaand endoplasmic reticulum .After exposure to temperature and copper, the ultrastructure ofthe liver with TEM is changed, so is the mitochondria and endoplasmic reticulum. It's anindicator for its expression in function.The result is as follows:1,After exposure to temperature and copper, the ultrastructure of the mitochondriachanged, especially in its function.2,It can be seen clear for the two kinds of endoplasmic reticulum, except for exposureto the temperature and copper.3,The effect is evidence with the higher temperature.4,The extent is evidence with the higher (0.01mg/l,0.30mg/l,0.40mg/l,0.70mg/l),when in the stated (10℃,20℃)temperature.5,The extent is evidence with the temperature in higher temperatur(e10℃,20℃),whenexposed to the stated density.
