title: [Effect of a modified terrilytin on ampicillin pharmacokinetics in experimental peritonitis].
abstract: The effect of modified terrilytin, a new enzyme of the microbial origin on the pharmacokinetics of ampicillin in experimental peritonitis was studied on 16 pubertal rabbits. Peritonitis was caused by laparotomy and administration of a 15 per cent fecal suspension into the abdominal cavity. The drugs were injected intramuscularly: the enzyme in a dose of 5 PU/kg and the antibiotic in a dose of 10 mg/kg. The ampicillin levels in the blood and peritoneal exudate were determined with the agar-diffusion method. The specimens were collected 30 minutes, 1, 1.5 and 2 hours after administration of the drugs. The animals were divided into 2 groups: control (not treated with the enzyme) and experimental. An increase in the antibiotic levels in the blood and peritoneal exudate by 50--54 per cent was observed. The maximum increase was recorded 30 minutes after simultaneous administration of the drugs.
