The influence of nitrogen supply on accumulation of overground biomass shooting and shoot qualitative characteristic in various cenoses of spring barley. pp. 25--32
Summary: Under stationary field trial conditions on derno-podzolic loamy soil and at different levels and terms of nitrogen application it was revealed that an increase in the level of nitrogenous nutrition reduced stability of grain yields under stress ecological conditions, resulting in their variations over the years. Disturbance in self-regulation mechanisms of tillering processes at high levels of nitrogen supply was the cause of stability decrease. It is shown that the value of biomass accumulated by sowing at the complete tillering stage call serve as the criterion for estimating its state.

Energy state of rat brain synaptosomes in acidosis. pp. 55--60
Summary: The influence of acidosis (pH 7.4 -- 6.0) on energy state of rat brain synaptosomes was studied. It was shown that intrasynaptosomal mitochondria are a primary target for acidosis. At pH 6.9 -- 6.0 there was a rapid reduction in ATP content and O2 consumption rate, both effects (pH 6.0) being prevented (32%) by preincubation in glucose-free medium using 5 mM pyruvate as a mitochondrial substrate. Incubation of synaptosomes at pH 6.0 resulted in the inhibition of glycolysis (a decrease in lactate content at pH 6.4 -- 6.0) was monitored. This effect was observed upon depolarization of intrasynaptosomal mitochondria by a combination of rotenone and oligomycin indicating non-involvement of mitochondria.

Phosphoinositides of endoplasmic reticulum in etiolated oat seedlings. pp. 61--66
Summary: The ratio and kinetics of the phosphate (32P) incorporation into phosphoinositides and phosphatidic acid of endoplasmic reticulum (EPR) membranes isolated from etiolated oat seedlings were studied. It was shown that EPR membranes contain PA, PI, PIP and PIP2 in the ratio of 25:86:3.4:1. Polyphosphoinisitides PIP and PIP2 have rapid kinetics of the 32P incorporation (t1/2 < 10 min).

Formation of Phenolic substances by Penicillium terlikowckii. pp. 73--79
Summary: Formation of phenolic substances by Penicillium terlikowckii fungus was shown to take place in a broad range of medium pH with optimum 7.0. Glucose and sodium pyruvate proved to be the most suitable sources of carbon for phenolic compound synthesis. Aromatic amino acids, n-oxybenzoic acid. b-indole acetic acid, a-naphthyl acetic acid and 6-furfurylaminopurine exerted a great effect on synthesis of common phenols. Flavanon glycosides were detected among products of phenolic metabolism.

The influence of hypoxia on bioelectrical activity of myocard cells after acute g-irradiation. pp. 85--90
Summary: Our findings indicate that gamma-irradiation at 0.5 Gy results in decrease in amplitude and duration of action potentials or right atrial cells, attenuation of the dependence of these electrophysiological characteristics upon the stimulation frequency, depression of the interval of cardiomyocytes reaction on the hypoxia. The revealed post-radiation changes determine the reduction in function resistance of heart cells bioelectrical activity and promote the initiation of arrythmies.
