title: [Lysozyme activity in the leukocytes and blood serum of white rats administered massive doses of penicillin preparations].
abstract: Activity of lysozyme in the blood serum and leucocytes was determined. The experiments were carried out on albino unbred rats weighing 170 to 200 gm. Benzylpenicillin and oxacillin were administered intramuscularly in doses of 500000 Units/kg or 20000 gamma/kg once every 24 hours for 2, 4 and 6 days. The activity of lysozyme was determined by the turbidimetric and agar-diffusion methods. It was found that the activity of lysozyme in the leucocytes increased by the 5th day accompanied by a simultaneous decrease in its level in the serum followed by reaching the initial values. The data are indicative of the fact that the use of antibiotics in mega-doses is not contraindicated from the point of view of their effect on lysozyme activity.
