摘要

Arginase (L - arginine amidinohydrolase), which catalyses the hydrolysis of L - arginine into L - ornithine and urea, was first detected in mammalian livers as the terminal enzyme of the urea cycle (Greenberg, 1960). Arginase activity occurs also in other tissues, which are devoid of a complete urea cycle ( Pohjanpelto and Holtta, 1983; Skoy et al, 1981; Schneider and Dy, 1985 ). In the later instance, the importance of arginase may be in the production of ornithine for the synthesis of the polyamines putrescine, spermidine and spermine, which are required for normal cellular proliferation (Pegy and McCann, 1982; Tobor and Tobor, 1981) and differentiation (Pegg, 1986). Arginase activity at the site of wounds plays a role in the recovery of host tissues from inflammation and infection (Guoyao et al, 1998). The distribution of arginase between the organs of normal human (Reyero and Doner, 1975; Spector et al, 1982, 1983; Zamecka and Porembska, 1988) and domestic animals (Aminlari and Vaseghi, 1992) has been studied. There is little recent further information on the distribution of arginase activity in the tissues of the camel, apart from the report on arginase distribution in tissues of domestic animals by Aminlari and Vaseghi (1992) that the numberof camels and tissues was limited. The purpose of this investigation was to examine and compare the tissue distribution of arginase in camel. The results of these studies will help to assess the role and significance of arginase in different tissues ofcamel. Serum enzymes are monitored routinely in camels to detect and assess damage to various organs. This study would assist the rational interpretation of serum arginase data in camel.
