RNA-binding properties of the 63 kDa protein encoded by the triple gene block of poa semilatent hordeivirus.

The 63 kDa '63K' movement protein encoded by the triple gene block of poa semilatent virus (PSLV) comprises the C-terminal NTPase/helicase domain and the N-terminal extension domain, which contains two positively charged sequence motifs, A and B. In this study, the in vitro RNA-binding properties of PSLV 63K and its mutants were analysed. Membrane-immobilized 63K and N-63K (isolated N-terminal extension domain) bound RNA at high NaCl concentrations.

[Redergin treatment of hypertensive menopausal women].

Aim: To assess a hypotensive effect of redergin (dihydroergotoxin)--agonist of dopaminergic receptors--in monotherapy (4.5-6 mg/day) and in combination with enalapril and amlodipin (10 mg/day).

Material And Methods: Redergin in monotherapy or combined therapy was given to 106 hypertensive women in pre- or postmenopause and 24 hypertensive women of reproductive age.

[Features of dopaminergic system function in menopausal females with arterial hypertension].

Aim: Assessment of dopaminergic activity by changes in urine excretion of dopamine, arterial hypertension, blood prolactine, 24-h diuresis and natriuresis in response to a single (2.5 mg) and 7-day (daily dose 5 mg) administration of parlodel in patients with essential hypertension (EH) in menopausal and reproductive age having different serum levels of estrogens.

Materials And Methods: The indices of 52 hypertensive menopausal women and of 18 women at reproductive age of whom 8 had hypothalamic syndrome were followed up.

[The effect of different factors on cardiac rhythm variability in patients with arterial hypertension].

The purpose of this study was to evaluate the influence of different factors, among them left ventricular hypertrophy (LVH) on long-term heart rate variability (HRV) in patients with hypertension. 38 patients with arterial hypertension of different genesis were included in the study. Ischemia was excluded in all the patients by the data of clinical and instrumental methods of investigation.

Influence of left ventricular hypertrophy on heart rate variability in hypertensive patients.

Long-term heart rate variability (HRV) data were obtained from 38 patients with arterial hypertension and 20 healthy persons. New method of HRV analysis based on calculation and estimation of variations of short rhythmogram intervals (SRV) was applied. This method showed that HRV level depends on number of factors.
