RESUMEN
Thirty-five specimens of pasteurized milk were tested for bacterial contamination by rapid autocalibration photometry for liquid, semiliquid, and homogenized hard foodstuffs, developed by the Ecotest Firm, Russia. Photometric (turbidimetric) analysis was carried out using the Labsystems (Finland) iEMS Reader plate photometer and Russian Analitika BACT software. The results of traditional analysis and the new rapid method developed by Ecotest were in good correlation, the differences did not surpass the magnitude of errors of measurements. The new method takes just 10-15 h instead of the routine 72 h and requires 300 times less nutrient media.

Twenty-seven pregnant women with cicatrices on the uterus after cesarean section had US-monitored spontaneous deliveries with calypsol analgesia (the drug was permanently i.v. infused). The intactness of the uterine walls in the postpartum period was checked up by bicontrast ultrasonic scanning and hysteroscopy.
