[Role of phlebography in surgery of recurrent varicose veins of the lower limbs].

It is believed by the investigators of recurrent venous varicosity of lower limbs that phlebography aids to detect errors of the performed operative procedure and to reveal what caused the recurrence. The authors' experience comprise 48 distal, ascending, vertical phlebographies, and 47 pelvic and retrograde femoral ones in 60 patients, both explorations being utilized for 28 lower limbs. Distal phlebography in 44 of 48 examined patients indicated insufficiency of perforated veins that caused the recurrent crural varices. It is considered that in surgical therapy for venous varicosity a due consideration should be given for both a liquidation of recognized errors of the preceding surgery and a correction of pathological changes in deep veins of the lower extremities.

[The mechanisms of the neuroprotective action of carbonate mineral baths in ischemic brain lesions].

Effects of Arzni effervescent mineral baths (EMB) on brain tissue metabolism were studied on white rats (normal controls and those with transitory cerebral ischemia). It was found that EMB prevent ischemia-related disorders of phospholipid and adeninnucleotide pools, promote an increase in vasoactive prostaglandins in brain tissue, shifts in catecholamines concentrations in the hemispheres and hypothalamus, inhibit the activity of monoaminoxidase and absorption of 3H-noradrenaline by brains sections. Mechanisms of neuroprotective action of Arzni EMB in cerebral ischemia are considered.
