[Histologic examination of some hippocampus fields after experimental ischemia].

The examinations of rats hippocampus were made after ischaemia (the rats vertebral and common carotid arteries were closed for 20 minutes). Serial sections of the brains were stained with hematoxylin and eosin. 24 hours after completing the experiment a small number of cells in the field CA1 was damaged.

[Histoenzymatic examination of the rat kidney following experimental administration of rocefin and furosemide].

Histochemical studies were conducted on kidney sections of white rats, which were given Rocephin, Furosemide and Rocephin with Furosemide for 7 days. The results show changes in the activity of cellular enzymes like acid phosphatase, alkaline phosphatase and in polysaccharides. Some of kidney's bodies were destroyed after the treatment with Rocephin jointly with Furosemide.

Histological examinations of the influence of 6-hydroxydopamine (6-OH-DA) upon the ileum of the guinea pig.

Examinations of the influence of 6-OH-DA (6-hydroxydopamine) upon the structure of nerve cells and their axons have been conducted by many authors and in various aspects (1, 2, 8, 10). They have concerned histochemistry, fluorescence and ultrastructure of neurons and have shown that the substance evokes various changes in the perikaryons and axons of adrenergic neurons. The wall of the small intestine is innervated by external autonomyous nerves and fibres of the intramural autonomyous plexuses.

Influence of Metizol ("polfa") on the liver of pregnant rats.

Drugs are the largest group of substances inactivated by the liver. They may have a stimulatory or inhibitory effect on the system of hepatic enzymes. Metizol is a thyrostatic belonging to the group of trimidazole derivatives.
