The influence of pharmaceutical vermipreparations on the test-reaction of organisms of the different levels of the organization.

The efficiency of vermipreparations has been investigated with the help of the test-reactions on various invertebrate organisms, plants and microorganisms. The principal possibility of the use of biotest on the basis of yeast, fungi, algae, water and ground-based plants, sponges, protozoan, small crustaceans, oligochaetes for an estimation of biological activity of vermipreparations and in further and for definition of quality, selection of dose of medicinal complex preparations is shown.

Stercoral colitis: a lethal disease-computed tomographic findings and clinical characteristic.

Objective: The aim of this study was to describe the radiographic findings in stercoral colitis.

Methods: The computed tomographic scans and abdominal radiographs of 13 patients with surgically and pathologically confirmed stercoral colitis from 4 affiliated hospitals were reviewed by a board-certified abdominal radiologist blinded to the official imaging, surgical, and pathologic findings.

Results: The median age was 66 years.

[Use of a biotesting method to determine the toxicity of medical waste].

Classes B and C medical waste is of particular concern since it is an epidemiological and toxicological hazard. Predisinfection of Class B medical waste with the chemicals that have different toxicity levels, as well as further burial in the urban landfill were a reason for defining its hazard classes by biotesting in order to establish the possibility of additional environmental pollution. Class B (epidemiologically hazardous) medical waste was ascertained to be little dangerous and indangerous to the environment.
