1·The excretion of methyl mercury becomes very difficult because of high enterohepatic circulation and reabsorption by proximal convoluted tubule.

由于甲基汞在体内的肠肝循环和肾脏近曲小管对甲基汞的重吸收效率高，使甲基汞的体外排泄十分困难。

2·The main renal injury location was in proximal convoluted tubule.

病理观察到肾损伤的部位主要是皮髓交界处的近曲肾小管。

3·A lot of lysosomes were seen in the cytoplasm of the renal proximal convoluted tubule cells.

肾近曲小管细胞的胞质内有大量溶酶体。

4·The kidney proximal convoluted tubule cells changed into megalocytes and the plasma caved in the nucleus.

肾脏近曲小管上皮细胞肿大，胞浆内陷；

5·The acidophilic granules in the proximal convoluted tubule of the kidney in Tilapia nilotica were studied by electron microscopy, enzyme histochemistry and enzyme cytochemistry.

用电镜和酶组织化学技术探明了尼罗罗非鱼（Tilapianilotica）肾近曲小管细胞嗜酸性颗粒的结构实质、来源和存在意义。
