Abstract

The levels of benzylpenicillin on its intramuscular administration in doses of 100000 or 200000 units, as well as the renal and hepatic functions and the antibiotic binding by the host protein components were studied in 44 angina patients and 29 healthy persons. The benzylpenicillin levels were always markedly higher in the angina cases than those in the healthy persons. The ratio of the free and protein bound fractions of the antibiotic in the above groups was practically the same. At the same time the amount of benzylpenicillin excreted with the urine was higher in the angina patients than in the healthy persons approximately by 2 times. The study of the function of the internal organs revealed a marked decrease in the daily diuresis in all the angina patients and microhematuria in the 1/4 of the cases. The impairment of the renal function was determined by the laboratory methods practically in all the patients. On the basis of the data obtained it was concluded that the increased benzylpenicillin levels in the angina cases were connected with a decreased capacity for inactivating this substance by the liver enzymatic systems due to the changed function of this organ. The fact of the increased antibiotics levels in the host i...Continue Reading
