[Lethal manifestations of meteorological and cosmic factors].

Data on mortality in Moscow region during 1977 to 1996 reveal that total mortality per 1000 citizens is 3 to 4 times less than it occurred at the beginning of XX century. Catalogue of intense geomagnetic storms is compiled for 1867 to 1996. Separation of data for geomagnetic-quiet and stormy years has shown that mortality during stormy years is increased by 30% as compared with quiet years.

[The determination of ethylene glycol in biological objects in the presence of propylene glycol].

Therapeutic application of drugs containing propylene glycol 1.2 as a solvent may distort the results of forensic chemical detection of ethylene glycol from its oxidation products. Practical examples illustrate the possibility of ethylene glycol determination by gas chromatography in the presence of propylene glycol.

[The biochemical indices of the blood serum in experimental hepatitis A in tamarins].

Serum biochemical parameters were studied in 42 healthy wild-caught adult tamarins (S. mystax), males and females, to determine the normal values. Blood samples were drawn repeatedly, and the serum was tested for aspartate aminotransferase, alanine aminotransferase, isocitric dehydrogenase, serum glucose, serum urea, triglyceride, cholesterol, albumin, and total protein.

[The determination of ethylene glycol in blood and urine].

Method of ethylene glycol isolation from blood and urine with subsequent gas-chromatographic determination was developed. The method makes it possible to extract 60-80% of ethylene glycol and to detect its toxic concentration in the cadaveric blood and urine.

[The modelling of hepatitis A and of enterally transmitted non-A, non-B hepatitis (hepatitis E) in Saguinus mystax tamarins].

A comparative study of hepatitis infection caused by human hepatitis A virus (MS-1 strain), simian hepatitis A virus (AGM-27 strain), and enterically transmitted non-A, non-B hepatitis virus (Tashkent-1435 strain) was carried out. Susceptibility of tamarins to the AGM-27 and Tashkent-1435 as well as to MS-1 strain was demonstrated. All the strains induced an acute infection characterized by serum alanine aminotransferase (ALT) elevation, virus excretion and antibody response.
