[Effect of chemical sympathectomy on the age dynamics of the heart rate and sensitivity of the heart to adrenaline and acetylcholine].

The guanethidine sympathectomy in 4- and 8-week old white rats increased cardiac sensitivity to acetylcholine. An increase of sensitivity to adrenaline was observed in 8 to 20 weeks of postnatal period. The significance of the changes of extracardiac effects and the cardiac sensitivity to acetylcholine and adrenaline for its chronotropic control in sympathectomized 10-14 week old rats is discussed.

[Types of urination in men according to urodynamic flow measurement data].

The work is grounded on the analysis of the urination parameters, obtained from the examination of 195 men with various urological pathologies and of 100 healthy individuals, through urodynamofluometry--a new method of the express-diagnosis of the urination disorders. 5 types of the urination according to its volume have been distinguished. The devised system of the quantitative-qualitative evaluation of the urination is an attempt to differentiate various conditions of the urodynamics of the lower urinary passages versus the peculiarities of their anatomo-functional state in men.

[The effect of vitamin E and rancid fish liver oil on the spinal cord motoneurons of white rats].

Using the "August" white rats, the influence of alpha-tocoferol (5 mg dose per day per animal) and of its antagonist--rancid fish oil (5% ratio in the food) on the cytophysiological properties of motoneurones was studied. Tocoferol caused a functional exhaustion of motoneurones. The rancid fish liver oil caused abnormalities in the specific function of motoneurones. Vitamin E administered after castration brought about further removal of changes, evoked by castration, whereas the rancid fish liver oil introduced after castration was seen to enhance distrophical lesions.

[Descending urethrography in men with low urine flow].

The paper describes a method of shuttering mixed cystourethrography in patients with low volumetric rate of urination that permits one to stop urination for the period of time necessary to fill the urethra but avoiding its overload and the development of venous refluxes. The aforementioned method was tested in 29 patients with stenosis of urethra and urocyst neck and proved the possibility to obtain the clear picture of urethra below its stricture, to measure its length and diameter.
