RESUMEN
The liquid content of the hydrocele or watery hernia presses blood vessels of the testis. This pressure occurs in the accordance with hydrostatic and hydraulic laws. However, none of 223. 568 studies on the pressure in mammalian organisms registered worldwide has reported on the pressure values in case of testis hydrocele. Results obtained by observation of 20 patient with testis hydrocele suggested that the hydrostatic pressure of testis hydrocele always surpassed the pressure of blood vessels within the scrotum, proving that the pressure of a fluid as a mechanical factor plays an important role in the malfunction of spermatogenesis as well as in hypoxemic hypoxia of the testis.

The paper describes the research in the field of thermodynamics. It deals with the function of capsule adipose renis. This homogenous tissue of low temperature acts as an independent thermal conductor. In fact, by encapsulating the kidney, it acts as a vacuum-flask, providing insulation for the kidney from two surrounding thermal areas, the warmer being on the interperitoneum and the cooler on the skin surface.

The findings obtained by excretory urography in 15 patients of various age and occupation confirmed the study premise that in the upright position after the procedure of supravesical urine derivation as described by Bricker, the isolated segment of the ileum does not function as a conduit but forms a siphon-like receptaculum which, according to the laws of liquid mechanics, prevents or reduces the ascent of gases and bacteria into the upper urinary ducts. This also appears to be a logical explanation for a decreased incidence of infection of proximal urinary ducts in Bricker's method of supravesical urine derivation as compared to other mechanically comparable surgical procedures.

Functional differences between surgically attacked musculature of the lumbal region and intact musculature of the contralateral side were assessed in 71 patients by the method of Multic-Labar, Moire topography, electromyography and X-ray analysis of the thoraco-lumbar spine. The following conclusions were derived from the results obtained. In the intact musculature of the lumbal segment of the spine, sliding forces reached 200 kN in males an 170 kN in females aged >25 and <30 years. In younger and older age groups, the values were lower, assuming a form of the ascending and descending limb of a parabole, respectively. Upon healing, the lumbal musculature damaged by surgical resection showed decreased values of the pulling and sliding forces by 15 and 25 kN on an average, respectively, as definite values independent of age and sex. Kinematic alterations included myogenic geneses of a stationary form, with normal innervation, involving the whole damaged musculature. Summa summarum, results of analyses suggested the values of kinematic forces of pulling and sliding forces of the musculature damaged by surgical resection to be definitely significantly reduced, thus confirming the premise of the study.
