[Use of xidifon for prevention and treatment of nephropathies with metabolic disorders in children].

Xydofon was applied to the treatment of 68 children suffering from different renal diseases associated with metabolic disorders. The latter ones involved oxaluria (28 children), uraturia (17 children), cystinuria (14 children), and phosphaturia (9 children). To appraise the action of xydofon, use was made of the indicators of membranolysis, cellular homeostasis of calcium, lipid peroxidation, and of the level of beta 2-microglobulin in urine.

[A new method of topical detection of accessory conduction pathways in patients with Wolff-Parkinson-White syndrome].

ECG mapping (90 leads) from the chest surface was used to examine 30 patients with the ventricular preexcitation syndrome. By applying endo- and epicardial mappings, 24, 3, and 1 patients were found to have one, two, and three accessory Kent's bundles, respectively. Two patients with Macheim's tract underwent surface mapping during the maximal preexcitation made via the nodoventricular tract.
