[Experimental characteristics of the neurotropic spectrum of some antiepileptic agents].

Investigation of the psychotropic spectrum of phenobarbital, diphenin, milontin, pufemide, sodium valproate (depakine), and diazeparn showed that, besides antagonism with the corazole and electroshock effects, all these drugs prevented to a considerable degree the kindling seizures in rats on a "tonsil swing" (chronic electroencephalographic partial epilepsy) model. The mechanism of this effect probably involves exciting amino acids. All anticonvulsants except for diazepam also restored memory in experimental animals with retrograde electroshock amnesia.

Right ventricular endomyocardial fibrosis. Diagnosis and management.

The clinical course, noninvasive and invasive diagnostic findings in 4 patients (pt) with endomyocardial fibrosis are reported. All patients (16-50 years) were in functional class III-IV (NYHA). Central venous pressure with large a- and v-waves was elevated in all; liver enlargement and peripheral edema were also noticed in all pts, and ascites in 3.

The effects of two strains of influenza virus on cardiac development in the chick embryo.

To investigate the teratogenic effects of influenza virus on cardiac development two strains of influenza virus (Ty/Calif/5142/66 and Ty/Calif/64/M. Meleagrium) were injected into the yolk sac of fertile white Leghorn eggs during stage 23. Eggs injected with normal saline served as controls.

Unusual cardiovascular manifestations in a case of pheochromocytoma.

A case of proven pheochromocytoma is reported of a patient who presented with attacks of apparent hypotension, pulmonary edema, and myocardial injury with typical ECG and enzyme change. In spite of unmeasurably low peripheral blood pressure recordings during the attack, central aortic pressure was well above 240/140 mmHg. A clinical shocklike state was in effect due to severe arterial vasoconstriction.

Myocardial metal content in patients who expired from cyanotic congenital heart disease and acute rheumatic heart disease.

The importance of metals in normal and pathologic cardiovascular function has been recognized. Significant derangements in myocardial Ca2+, Mg2+, and Cu2+ have been reported in ischemic heart injury. We studied 3 groups of hearts: 1) fifteen specimens obtained from patients who had no heart disease, 2) nine specimens from patients who had expired from cyanotic congenital heart disease, and 3) ten specimens from patients who had expired from acute rheumatic heart disease with carditis and severe heart failure.
