    Abstract:
    All subjects were patients with malignant tumors on the gastroenterological system and in whose cases there were marked ascites (Table 1). In the study, each patient was subjected to the intravenous drip infusion of CTM 1 g for a period of 1 hour. Samples of peripheral venous blood and ascites were taken 4 times, at 1 hour after completion of infusion, and at 2, 3 and 4 hours. The test samples were kept at -80 degrees C until the CTM contents were determined (Fig. 1). Determination results 1. Blood concentrations of CTM decreased with the passage of time (Fig. 2). 2. There was hardly any difference in the concentration of CTM in ascites between the 1 hour and 4 hour samples. Furthermore, the concentration was maintained which exceeded the MIC against intestinal flora, including Escherichia coli, without Pseudomonas and Bacteroides (Fig. 3, Table 2). 3. The higher serum creatinine levels were the greater the concentration of CTM in blood (Fig. 5). 4. The maximum blood and ascites concentration of CTM indicated a correlation coefficient of 0.809, P less than 0.01 (Fig. 6). These results led to the following conclusions: 1. If 1 hour intravenous drip infusion of CTM 1 g/100 ml is to be carried out against postoperative peritoneal infection, such administration at interval less than 5-hours would not be reasonable. 2. The peritoneal invasion of malignant tumor is not a factor in the inhibition of CTM transition from blood to ascites.
