[Postinjection changes in angiopathy patients].

The results are presented of studying the response of the foot skin blood microcirculatory vessels after injecting 2ml of saline solution of NaCl into the hip. A group of patients with diabetes mellitus aggravated by angiopathy of low extremities was managed with insulin during 4 to 18 years and examined versus insulin-untreated diabetes mellitus patients, persons with low limb obliterating thromboangiitis and healthy volunteers. The studies were carried out, using the "skin window" method, which allows one to investigate not only the capillary function but also the state of other skin microcirculatory units. It was determined that at rest the functioning microvessel density per the tissue area unit is compensatory enhanced in patients with angiopathy. The pain irritating effect (the injection) is integrated into a stereotypic vasospastic response in all the persons under study, becoming pathologically persistent in patients with angiopathy. It was concluded that the maximum tissue sparing is necessary during the injection therapy, considering this procedure as a factor of arising and developing the vessel affection, especially in diabetes mellitus insulin-treated patients, subjecting to systematic insulin injections.

[New instruments for pediatric cardiovascular surgery].

The new instruments well adapt anatomical structures of children. Such features as specific dimensions and configuration, light weight, and easy in operation make them suitable for wide application in pediatric surgery.

[The prognostic significance of the blood flow volume of the abdominal cavity in peptic ulcer patients].

A total of 25 patients with duodenal ulcer were examined. Central bloodflow, that of the abdominal cavity, and characteristics of the vegetative tone were studied by the variation pulsometry method. Disturbances were revealed in the hemodynamics, manifested by a drop in cardiac output (CO) and increase in the blood volume which were particularly pronounced in unfavourable course of the disease. It has been established that the abdominal cavity CO above 1.55 l/min suggests a favourable course of the disease, while its lower values are thought to be associated with unfavourable one. The influence of the vegetative nervous system on the abdominal cavity hemodynamics is not unidirectional.
