[A sixty-eight-year-old man with giant intracranial arteriovenous malformation and right-sided hemicrania -- a case report].

Arteriovenous malformations (AVMs) are the most dangerous congenital vascular malformations. Intracranial AVMs occur in about 0.1 percent of the population and account for 1 to 2 percent of all strokes.

Changes in the structure and function of the kidney of rats chronically exposed to cadmium. II. Histoenzymatic studies.

Early effects of cadmium (Cd) on the structure and function of the kidney were studied in an experimental model using rats intoxicated with Cd at the levels of 5 and 50 mg Cd/l drinking water. The effect of Cd was evaluated histopathologically and biochemically. Damage to the cellular structures was assessed on the basis of histoenzymatic analyses of the activity and localization of indicator enzymes (succinate dehydrogenase, lactate dehydrogenase, glucose-6-phosphatase, Mg(2+)-dependent adenosine triphosphatase and acid phosphatase).

Effect of non-steroidal anti-inflammatory drugs on the anticonvulsive activity of valproate and diphenylhydantoin against maximal electroshock-induced seizures in mice.

Prostaglandins and their inhibitors may affect convulsive phenomena. Thus, the aim of this study was to examine possible interactions between non-steroidal anti-inflammatory drugs and two conventional antiepileptic drugs in terms of their anticonvulsive activity and side-effects. Also, the plasma levels of antiepileptics were measured in order to delineate possible pharmacokinetic interactions.

Competitive NMDA receptor antagonists enhance the antielectroshock activity of various antiepileptics.

CGP 37849 (1 mg/kg i.p.) enhanced the protective action of carbamazepine, diphenylhydantoin and phenobarbital against maximal electroshock-induced convulsions in mice.
