[Binding of aromatic compounds to cornstarch polysaccharides].

Sorption of aromatic compounds from aqueous solutions by cryotextures and suspensions of native cornstarches was studied by capillary gas chromatography. Acetophenone and benzyl alcohol were not sorbed by cryotropic-cornstarch gel and native-cornstarch suspension. A linear concentration dependence was found for aldehydes.

[Changes in the composition of the essential oil in stored marjoram].

The composition of volatile components of the essential oil of marjoram plants (Majorana hortensis M.) and its stability during storage were studied by capillary gas chromatography and gas chromatography/mass spectrometry. Storage in the dark for 1 year was associated with insignificant changes in the composition of the essential oil, and its organoleptic characteristics remained largely unaffected.

[Alcohol abuse in HIV infection].

249 cases of HIV infection (170 males, mean age 30.2 +/- 0.8 years; 79 females, mean age 28.

[The anxiety state in HIV-infected persons after the discovery of their seropositivity].

The authors analyzed psychoemotional reactions of 225 subjects (151 males and 74 females, mean age 30.2 and 27.8 years, respectively) to detection of HIV in their blood serum.
