[Comparative analysis of amphetamine identification by immunoenzyme assay and gas chromatography with mass spectrometric detection].

The objective of this study was to simultaneously identify amphetamine in biological materials by enzyme-linked immunosorbent assay (ELISA) and gas chromatography with mass spectrometric detection (GH/MS) for the verification of diagnostic value of the proposed ELISA technique. Urine samples from suspected amphetamine and related drug users were available for analysis. It is concluded that the new modification of ELISA can be recommended for application in narcological practice and for the purpose of forensic medical examination.

[Seasonal dynamics of diel changes in inshore benthopelagic communities of the Black Sea by the example of the Golubaya Bay (Gelendzhik Town)].

Seasonal and diel changes in littoral plankton in the Golubaya Bay (near Gelendzhik Town) were studied at seven daily stations from October 1999 to September 2000. In the night-time, the plankton included both holoplanktonic and demersal species rising to the upper layers (benthopelagic plankton). The role of benthopelagic and holoplanktonic organisms in relation to the time of the day, season, and phase of the moon was determined.

[Individual prognosis of the risk of primary and secondary female infertility].

The authors suggest methodologic approaches to individual prediction of the risk of primary and secondary female sterility. A total of 512 women suffering from infertility were examined, and the major biomedical and ++socio-hygienic risk factors were detected. ++Socio-hygienic factors were found conducive to the development of biomedical factors or augmenting their effects.
