Determination of water pollution by the oil products through UV photometry.

Results of UV photometry of water/gasoline systems are reported. It was found that this system can be characterized with an analytical light absorption peak with maximum at 260 nm. A calibrating diagram for optical density vs.

[Capacities of digital mammography in screening].

The purpose of the study was to estimate the capacities of digital mammography in screening in women followed up by a mammologist in the Surgut Clinical Perinatal Center. The results of analog and digital mammography were compared using a Senographe DS in 1772 subjects who had been followed up by a mammologist in the Surgut Clinical Perinatal Center for 3-7 years. Females in whom mammography was first made as a basic study on a digital mammography were identified in an individual group of 887 subjects.

[Clinico-functional evaluation of the efficacy of treating gastroesophageal reflux disease combined with bronchial asthma with omeprazole].

Aim: To investigate the prevalence of gastroesophageal reflux disease (GERD) among patients with bronchial asthma (BA) and to determine the effects of omeprazole therapy on the outcome of asthma in patients with GERD.

Material And Methods: 117 BA patients were examined. Those who had a concomitant GERD were divided into two groups to receive outpatiently omeprazole 40 mg/day or placebo for 8 weeks.

An efficient method for the synthesis of sulbactam pivoxil.

Sulbactam pivoxil, a prodrug of the beta-lactamase inhibitor sulbactam, was prepared in high yield by reacting the sodium salt of sulbactam with chloromethyl pivalate in a polar solvent, then diluting the reaction mixture with water and isolating the product by filtration. Dimethyl sulfoxide was found to be the solvent of choice among several aprotic organic solvents.

[The dynamics of erythrocyte metabolism in severe forms of meningococcal infection and suppurative meningitis in children].

In 63 children with severe meningococcal infection (MI) and meningitides of another origin red cell metabolism was studied: levels of ATP, ADP, AMP, ATP/ADP, ATP/AMP, energetic charge, 2,3-DPG, FAD, piruvate, lactate, activity of lactate dehydrogenase, piruvate kinase, glucose-6-phosphate dehydrogenase, glutatione reductase, Mg2+, Na+, K(+)-dependent ATPase. All the disease periods were characterized by combined pathobiochemical shifts of different degree typical for varying metabolic systems and correlating with the infection severity. The discussion covers pathogenetic and clinical significance of red cell metabolism shifts in patients with MI and purulent meningitides.
