[Spontaneous unit activity of locus coeruleus neurons after destruction of some nuclei of the medulla oblongata]. / Fonovaia impul'snaia aktivnost' neironov golubogo piatna krysy posle razrusheniia nekotorykh iader prodolgovatogo mozga.

Bilateral lesions of the nuclei prepositus hypoglossi produced a more than twofold decrease in the mean frequency discharges in the neurons of the nucleus coeruleus. The number of neurons with burst activity and the number of polymodal neurons substantially increased. Lesion of the nucleus tractus solitarius resulted in an increase in the number of neurons with regular activity and certain decrease in the mean discharge frequency of coeruleus neurons. The results confirm the suggestion about a substantial role of the nucleus prepositus hypoglossi in relaying afferent effects to the activity of locus coeruleus neurons.

[Detection of Mycoplasma and its antibodies in the blood of HIV-positive patients and in healthy persons]. / Vyiavlenie mikoplazm i antitel k nim v krovi VICh-pozitivnykh i zdorovykh lits.

The comparative study of HIV-positive and clinically healthy persons has indicated that the antigens of M. pneumoniae, M. fermentans and U. urealyticum are encountered nearly twice more frequently in the blood of HIV-infected patients than in that of healthy individuals. Mycoplasma antibodies are detected in HIV-positive persons 12 times more frequently than in healthy ones. Among the HIV-infected persons there are those who have simultaneously antigens of some Mycoplasma species.
