[Safety during the thermal disposal of medical waste containing PVC].

In the article the issues of environmental, sanitary and hygienic safety of medical waste management are considered. Recently, for the treatment of certain types of medical waste thermal methods using small plants not equipped with a proper flue gas cleaning system are widely used. In this article the potential danger of supertoxicants generation when applying thermal methods of neutralization of medical waste that contains polyvinyl chloride (PVC) is justified by thermogravimetric and mass spectrometric studies.

[Analysis of tear enzymes in the diagnosis of obstructive jaundice associated with subhepatic cholestasis].

The activity of enzymes, such as alkaline phosphatase, gamma-glutamyl transpeptidase, and leicine aminopeptidase, was found to be increased in the serum and tear of 28 patients with obstructive jaundice. In malignant tumor-induced jaundice, the activity of the enzymes, the indicators of cholestasis, was higher than that in obstructive jaundice caused by extrahepatic bile duct calculi. A new method has been devised for noninvasive diagnosis of obstructive jaundice from tear enzyme immunoassay.
