1) Sensitivity of 5, 4 and 3 strains of<I>E. coli, Serratia marcescens</I>and<I>Pseudomonas aeruginosa isolated</I>from patients, respectively, to CS-1170 was compared with that of cefazolin (CEZ), cephalothin (CET) and ampicillin (ABPC) The antibacterial activity of CS-1170 against<I>E. coil</I>and<I>Serratia marcescens</I>was superior to that of CEZ, CET and ABPC. However, all strains of<I>Pseudomonas aeruginosa</I>were insensitive not only to CS-1170, but also to other three antibiotics.<BR>2) Blood level and urinary recovery of CS-1170 were determined in two patients.<BR>Peaks of blood level by single intravenous injection of 1.0g of CS-1170 and a subsequent intramuscular injection of 0.5g were 78μg/ml at 15 min. and 15.5μg/ml at 30 min., respectively.<BR>Dose was recovered at 77.8% in urine within 2 hours after intravenous injection, and at 111.4% within 4 hours after intramuscular injection.<BR>3) Ten patients other than with mycoplasma infection responded well to CS-1170 therapy.<BR>With regard to haematological findings, erythrocyte counts, haemoglobin and haematocrite decreased in one patient, and eosinophile counts elevated in 2 patients.
