为了验证三聚氰胺的毒性作用，将16只大鼠分为4组，各组雌雄数量相同。其中的三组为实验组，口饲三聚氰胺用量分别为1/5 LD50，1/25 LD50，1/125 LD50 ，第四组为对照组。30d后测定大鼠血液中丙氨酸氨基转移酶（ALT）的活性，解剖并观察各器官的颜色及形态变化，比较各组大鼠脏器的脏体比值，并进行分析。结果显示，大鼠经喂三聚氰胺30d，试验组大鼠肾脏和肝脏出现显著损伤，并随着三聚氰胺用量的增加损伤加剧。由此实验可以判定三聚氰胺对大鼠肾脏和肝脏有毒性损伤作用，且剂量越高损伤越明显。
最好全用简单句
不要用第一人称

In order to verify the toxicity of melamine, the 16 rats were divided into 4 groups, each group the same number of male and female. One of the three groups for the experimental group, the amount of oral feeding of melamine were 1 / 5 LD50, 1 / 25 LD50, 1 / 125 LD50, the fourth group was the control group. Determination of rat blood after 30d of alanine aminotransferase (ALT) activity, anatomy and observe the color of the organs and morphological changes, compare the organs of the dirty rats body ratio, and for analysis. The results showed that rats fed melamine by the 30d, test kidney and liver in rats significant damage and an increase in the amount of melamine with aggravated injury. This experiment can be found melamine in rat kidney and liver toxic injury, and the higher dose, the more obvious injuries.
