Characterization of solid airborne particles deposited in snow in the vicinity of urban fossil fuel thermal power plant (Western Siberia).

Recognition and detailed characterization of solid particles emitted from thermal power plants into the environment is highly important due to their potential detrimental effects on human health. Snow cover is used for the identification of anthropogenic emissions in the environment. However, little is known about types, physical and chemical properties of solid airborne particles (SAP) deposited in snow around thermal power plants.

[The clinical efficacy of ticarcillin/clavulanate in severe pneumonia].

Efficacy of ticarcillin/clavulanate was studied in the treatment of 11 patients with severe community- and hospital-acquired pneumonia in an open controlled trial. The drug was administered in a dose of 3.1 g every 4 or 6 hours depending on the infection severity.

[The treatment of metastasis of liver cancer].

Of 1483 patients with malignant tumors, treated in 1992-1997 years in clinic, metastasis in liver were revealed in 304 (20.5%). Surgical treatment was performed in 23 (7.

[The diagnosis and surgical treatment of primary malignant liver tumors and metastases].

Results were analyzed of diagnosis and treatment of 314 patients with malignant tumours of the liver. Of these, 36 had primary tumours of the liver (PTL), 278 were presenting with metastatic tumours (MTL). In addition, an analysis was carried out in 1236 oncological patients in order that the frequency of metastasizing of tumours into the liver might be determined together with the specific weight of metastases of different locations.

[Program of empirical antibacterial therapy of community-acquired pneumonia].

Clinical and bacteriological efficacies of some antibacterial agents were estimated with their differential use in the management of various groups of patients with community-acquired pneumonia. Group 1 included young and middle-aged patients with mild pneumonia. Group 2 included young and middle-aged patients with moderate pneumonia.

[Stepwise therapy of community-acquired pneumonia. Results of cefuroxime and cefuroxime axetil study].

The efficacy of a 7-day switch therapy with parenteral cefuroxime in a dose of 750 mg for 3-5 days followed by the use of oral cefuroxime axetil in a dose of 500 mg every 12 hours was compared with that of a 7-day therapy with parenteral cefuroxime in a dose of 750 mg every 8 hours in hospitalized patients with community-acquired pneumonia. The clinical and bacteriological efficacies and pharmacokinetic properties of both the dosage forms were estimated. It was shown that the clinical and bacteriological effects did not significantly differ in the patients under the parenteral regimen with cefuroxime and under the parenteral-to-oral regimen with cefuroxime and cefuroxime axetil: the cure in 75 and 83 per cent of the patients and the bacteriological response in 100 and 86 per cent of the cases respectively.

[Use of piperacillin/tazobactam as empirical monotherapy in the treatment of bacterial infections in a resuscitation department].

Fifteen patients with severe bacterial infection (12 with pneumonia) that developed in the resuscitation unit were subjected to the empirical monotherapy with piperacillin/tazobactam (P/T) or tazocin under an open randomized controlled experiment. P/T was administered intravenously in a dose of 4.5 g every 8 hours for 5 to 12 days (9.

[Cefpirome--a fourth generation antibiotic for the treatment of severe hospital infections].

The efficacy of cefpirome was estimated in the treatment of 12 patients with severe hospital infection in the Municipal Hospital No. 7. The positive clinical effect at the background of the cefpirome use was recorded in 11 patients.

[Clinical trials of ofloxacin in sequential use (intravenous and oral) in patients with serious hospital infection].

Fifteen patients with severe hospital infections such as postoperative pneumonia or intraabdominal sepsis were treated with ofloxacin in a dose of 400 mg once a day for 7 to 14 days (11 days at the average). The drug was administered intravenously for the first 3-5 days and then orally till the end of the treatment course. The clinical effect was observed in 14 patients (93 per cent) and the positive bacteriological effect was stated in 11 out of 13 patients (85 per cent).

[Preparation and properties of acid proteinase from Aspergillus awamori].

From the culture liquid filtrate of Aspergillus awamori 78-2 a preparation of acid proteinase was isolated and its properties were described. This producer was shown to have a peculiar capacity of synthesizing under submerged conditions extracellular acid proteinase as the sole proteolytic enzyme. The preparation of acid proteinase showed a comparatively high hydrolyzing capacity.
