| Abstract: | Rabbits were poisoned by the intraperitoneal injection of plasmocid dihydroiodide at a dosage of 80 mg. per kg. body weight. Animals were euthanatized 1, 2, 5, 7, 9, 12, 24 and 48 hours after plasmocid injection and serum and diaphragmatic muscle collected. The serum was examined for its serum glutamic oxalacetic transaminase (SGOT) and creatine phosphokinase (CPK) concentrations. The diaphragm was sectioned and examined for the progression of morphologic alterations. It was found that SGOT and CPK concentrations were similar in their time and duration of elevation and that the serum CPK elevations closely paralleled the occurrence and degree of morphologic muscle degeneration. It appears that CPK is the most specific clinical biochemical test for the detection of muscle necrosis available at this time. |
