Groups of rats were fed diets containing 15% protein from arhar dal (Cajanus cajan), bengal gram dal (Cicer arietinum), urad dal (Phaseolus mungo) and also isolated proteins from casein, egg, soya bean, gluten and gelatin for a period of 10 days. Rats maintained on the casein diet had the highest liver arginase activity and those having egg the lowest. All the leguminous proteins gave similar levels of arginase activity, the values falling between the casein and egg groups. Serum arginase level was found to be low only in rats on egg and gluten diets. Liver ornithine transcarbamylase (OTC) activity was significantly higher when legumes provided the protein as compared with the diet containing egg. Serum OTC level was lowest in the egg and arhar dal groups. Though the levels of urea cycle enzymes were altered by the quality of dietary proteins, no simple relationship could be established between them.
将几组大鼠分别喂食含有来自鹰嘴豆（木豆）、孟加拉鹰嘴豆（鹰嘴豆）、黑绿豆（绿豆）的15%蛋白质的日粮，以及酪蛋白、鸡蛋、大豆、麸质和明胶的分离蛋白，持续10天。以酪蛋白日粮饲养的大鼠肝脏精氨酸酶活性最高，以鸡蛋饲养的大鼠肝脏精氨酸酶活性最低。所有豆类蛋白的精氨酸酶活性水平相似，其数值介于酪蛋白组和鸡蛋组之间。仅在以鸡蛋和麸质为日粮的大鼠中发现血清精氨酸酶水平较低。与含鸡蛋的日粮相比，当豆类提供蛋白质时，肝脏鸟氨酸转氨甲酰酶（OTC）活性显著更高。鸡蛋组和鹰嘴豆组的血清OTC水平最低。尽管日粮蛋白质质量改变了尿素循环酶的水平，但它们之间无法建立简单的关系。
