Peculiar Porous Aluminum Oxide Films Produced via Electrochemical Anodizing in Malonic Acid Solution with Arsenazo-I Additive.

The influence of arsenazo-I additive on electrochemical anodizing of pure aluminum foil in malonic acid was studied. Aluminum dissolution increased with increasing arsenazo-I concentration. The addition of arsenazo-I also led to an increase in the volume expansion factor up to 2.

[Differential selection of anti-anginal drugs in stable stenocardia in relation to the data of central and intracardiac hemodynamics].

Rheography and echocardiography were used to study central and intracardiac hemodynamic parameters in 196 patients with Functional Classes I-II from the screening of the main antianginal drugs during an acute pharmacological test under bicycle ergometric monitoring. It was established that the hemodynamic type of circulation and left ventricular end-diastolic and end-systolic volumes may be used as criteria for the differential choice of antianginal agents. The values of these parameters are given for sustac, propranolol, verapamil, nifedipine and sustac plus propranolol.

[Dynamics of the level of acylhydroperoxides and platelet aggregation in chronic ischemic heart disease and essential hypertension during treatment].

Platelet aggregation has been found to be increased in chronic coronary disease of any type, whereas the acylhydroperoxide level was only increased in anginal patients. Conventional therapy normalizes platelet aggregation in patients with angina or angina plus essential hypertension, yet it has no effect on acylhydroperoxides. In essential hypertension, platelet aggregation and acylhydroperoxides increase near the time of discharge.
