[Study of the root nodules in some species of the Papilionaceae subfamily by scanning electron microscopy].

Nitrogen-fixing nodules from 16 species in 6 tribes of the sub-family Papilionaceae have been examined by scanning electron microscopy. The structure of infection threads was similar in all the studied papilionoid species except Lupinus polyphillus. In this species the infection threads were found in young nodules only.

[Risk of halophilic morbidity in connection with the eutrophication of the seashore].

Significant role of the littoral eutrophication in the growth of parahemolytic vibrio caused acute gastrointestinal disturbance- halophilosis was described.

[Noradrenaline metabolism in the brain of young rats during formation of inherited stress-induced arterial hypertension].

The noradrenaline (NA) metabolism rate was studied in discrete brain areas of young rats with inherited stress-induced arterial hypertension (ISIAH rats) in the period of rapid hypertension formation (4th week, 22nd-23rd days of life). The rate of metabolism was evaluated according to the NA concentration regression lines after inhibition of tyrosine hydroxylase oridopamine-beta-hydroxylase. The level of NA and the rate of its metabolism in the posterior hypothalamus, midbrain, and pons were higher in ISIAH rats than in normotensive Wistar rats.
