Level of functioning of siblings and parents of probands of varying degrees of retardation

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group.

Anatomical study of distribution of valves of the cutaneous veins of adult''s limbs

Since the cutaneous veins of the four limbs have been used as autogenous grafts in the treatment of cardiovascular disorders, knowledge of distribution of the valves is increasingly required depending upon the use. In the gross anatomical study of distribution of valves of the trunci venae, there has been argument about locational relationships between the venous roots and the valves in the vicinity of the roots and the inter-valvular distance. However, there have been only few reports discussing detailed information about valves of the cutaneous veins of the four limbs. The authors observed patterns of distribution of the cutaneous venous valves of the four limbs of cadavers prepared for practice in anatomy. The following parts were excised from each cadaver: the cephalic, basilic, and the great saphenous veins, which originate from the acral venous network and flow into the proximal deep veins, and the venous roots communicating with these veins. An incision was made on each excised vein in the direction of the long axis under observation with a stereoscopic microscope, and the inter-valvular distance and the distance between the valve and the orifice of venous root in the vicinity of the valve were measured. The inter-valvular distance varied with type of the truncus venae, and it varied according to area even in the same truncus venae.

Mechanisms of generation of slow components of bioelectric activity in diagnostics of functional state of the gastrointestinal tract

New electrophysiologic devices were used for the diagnostics of the state of excitable structures in the gastrointestinal tract and correction of their motor functions. Bioelectrical and biomechanical activities form the basis of functioning of internal organs. The mechanisms of generation of slow bioelectrical activity that are important for clinical and physiological studies are described. One of these mechanisms is a capacitance parametric transducer converting the energy of contractions into specific electric signals reflecting muscle functions. Another mechanism results from slow oscillations of resting potentials of interrelated excitable cells in large neuromuscular structures of internal organs. The elaborated procedure is efficient for preventing early postoperative paresis of the gastrointestinal tract.

Assessment of the efficacy of treatment of hemangiomas

Assessment of the aftereffects of cryoexposure and ultrahigh-frequency cryoexposure on hemangioma tissue of various types, cavernous and squamous, showed a higher cryogenic effect in hemangiomatous tissue preexposed to ultrahigh-frequency waves. A quantitative criterion is proposed for assessing the efficacy of the studied methods of exposure.
