Activities of the specific enzymes of the inherited hyperammonemic syndromes (carbamoyl-phosphate synthetase CPS), ornithine transcarbamylase (OTC), arginine-succinate-synthetase (ASS), arginine-succinate-lyase (ASL) and arginase (ASE) were measured in a liver biopsy specimen of a 2 years-old girl suffering from chronic hyperammonemia and in the erythrocyte- and leukocyte-homogenisate of her parents. The activity of OTC in liver homogenisate of the patient was 62.9 percent; in the leukocytes of the parents it was 78.5 percent (in mother) and 102 per cent (in the father) as compared to the controls. Our patient proved to be a symptomatic carrier of OTC deficiency and her mother proved to be an asymptomatic carrier.
在一名患有慢性高氨血症的2岁女孩的肝脏活检标本以及其父母的红细胞和白细胞匀浆中,测定了遗传性高氨血症综合征(氨甲酰磷酸合成酶CPS)、鸟氨酸转氨甲酰酶(OTC)、精氨酸琥珀酸合成酶(ASS)、精氨酸琥珀酸裂解酶(ASL)和精氨酸酶(ASE)等特定酶的活性。患者肝脏匀浆中OTC的活性为62.9%;与对照组相比,其父母白细胞中OTC的活性,母亲为78.5%,父亲为102%。我们的患者被证明是OTC缺乏的症状携带者,其母亲被证明是无症状携带者。
