[Optimization of energy parameters of ultrasound and laser cataract surgery with a preliminary transcorneal endocapsular YAG-laser impact exerted on the cataract lens nuclei].

The values of the main energy and time parameters of ultrasound and laser fragmentation of different-hardness cataract-lens nuclei were analyzed in patients of various age groups after a preliminary transcorneal endocapsular YAG-laser treatment of the lens. The results show, in all cases, lower key energy and time characteristics, which primarily concerns a total energy index of the ultrasound and laser effect of no less than 20% versus the ordinarily used parameters.

[An assessment of the manifestation of the functional connections between brain structures].

Responses of hypothalamic neurons to single (1/s, 20 impulses) stimulation of the prefrontal (area 8), cingulum (area 24), periamygdaloideus (RPA) cortex and hippocampus (field CA3) were studied on experimental cats anesthetized with ketamine. The routine elaborated for IBM PC/AT 386 provided: 1) selection of such neurone reaction with the latent period variation less than its length per the set value (5-20%); 2) selection of repeated neurone reactions with the same variability of latent periods from 20 cortical stimuli; 3) ranging of neurone reactions according to these indices. Quantitative estimation of the priority ranges made it possible to determine the profundity of the functional relations between the cerebral structures.

[The conservative treatment of children with vesico-ureteral reflux].

The article deals with the results of examination and nonoperative treatment of 120 children with vesicoureteral reflux (VUR). Their ages ranged from 3 to 13 years. The authors used a complex of methods for the examination of the functional condition of the kidneys, upper urinary tract (excretory urography, renoscintigraphy, electroureterography, clearance tests), lower urinary tract (cystography, cystoscopy, cystotonometry, urethroprofilometry, electromyography of the detrusor and its obturator apparatus), bacterio- and immunological studies (determination of the microbial number, bacteria covered with antibodies, immunoglobulins G, A, and M). The results of the study were analysed in 3 groups in which VUR was linked with normoreflexia (33.3%, group 1), hyperreflexia (48.6%, group 2), and hyporeflexia (18.1%, group 3). There was an obvious growth of cystitis incidence in patients with bladder dysfunction. The data of computed scintigraphy showed partial renal dysfunction in patients with unilateral VUR not only on the side of the affection but also in the contralateral intact kidney. It is assumed that there is a clear relation between the degree of renal dysfunction, the ureteral motor activity, and bladder dysfunction. The treatment included: (1) pharmacotherapy of neurogenous bladder dysfunction with belladonna preparations (in hyperreflex) and aceclidine (in hyporeflex urinary bladder) in optimization of the organism's bioenergetic processes; (2) percutaneous bladder electrostimulation; (3) combination of the listed methods together with cerucal. The results of treatment and the indications (absolute and relative) for nonoperative treatment of VUR in children are discussed.
