[Neuromotor apparatus in the condition of gravitational unloading: central and peripheral effects].

The functioning of central and peripheral structures of the gastrocnemius m. neuromotor apparatus was studied in rats exposed to simulated gravitational unloading. Gastrocnemius reflex (H) and motor (M) responses evoked by electrical stimulation of the sciatic nerve were measured after 7, 14, 21 and 35 days of tail-suspension.

[Restriction analysis of the DNA of aleutian mink disease virus strain P-1].

The II-1 strain of the Aleutian disease virus (ADV-II-1) was isolated from experimentally infected mink organs. The viral particles were isolated having 23 to 24 nm in diameter with the buoyant density of the virions in CsCl gradient being 1.41 g.
