ABSTRACT
Female textile workers and women engaged into nonindustrial work were subjected to the examination including myometrium contractility, vegetative regulation, serum sex steroids level, some biochemical and histochemical parameters. The observed features of myometrium contractility in female textile workers were proved to associate with overactive vegetative regulation, hormonal disbalance and changes in some biochemical and histochemical parameters.

In 26 patients with coronary heart disease, transesophageal atrial pacing was used to study cerebral hemodynamics from brain tomoscintigraphic findings as compared to the severity of induced of myocardial ischemia, echocardiographic parameters of left ventricular function and prostacyclin-thromboxane balance. In angina pectoris, the lower rate of cerebral blood flow was found to be correlated with the integral parameter of myocardial ischemia, deteriorated cardiac contractile and pump function, and higher plasma thromboxane A2 levels.

As many as 50 children with the antenatal period complicated by prematurity risk were subjected to clinical and hormonal studies during the first year of life. To estimate adrenal function, excretion of 17-ketosteroids, corticoids and their fractions with urine was investigated. The children born in a satisfactory state with a physiological body weight and length demonstrated the lag in the establishment of motor and static functions as well as mental retardation. It has been discovered that the clinical course of the early neonatal and subsequent periods of the child's development is dependent on adrenal function.

Forty-nine patients, including 38 with documented bradysystolic sick-sinus syndrome (type I) and 11 with bradytachycardiac sick-sinus syndrome (type II) were studied. Follow-up of 24 patients with VVI stimulation (34 +/- 4 months) and 7 patients with AAI stimulation (23 +/- 1.2 months) demonstrated that VVI stimulation was associated with retrograde ventriculo-atrial conduction in 71% of patients, causing paroxysms of atrial fibrillation (5 patients, 4 of those having type I sick-sinus syndrome). Six patients developed permanent atrial fibrillation (including 5 with type I sick-sinus syndrome). Retrograde conduction slowed down the pulse rate because of ineffective ventricular response in 6 patients. Nine patients with retrograde conduction developed circulatory insufficiency.
