The influence of experimental administration of ethanol and cephalexin on stomach mucous barrier of rat.

The Wistar rat males weighing approximately 200 g were administered 20% ethanol ad libitum during 10 days, cephalexin in the dose of 42 mg/24 h, and simultaneously ethanol and cephalexin in the above-mentioned doses. After 10 days the animals were decapitated and stomach specimens were taken from the major curvature region for examinations. They were fixed in 10% formalin, dehydrated and immersed in paraffin.

Histological examinations of chief and parietal cells of the rat gastric glands after experimental administration of cephalexin and ethanol.

The experiment was carried out on Wistar rat males weighting about 200 g. Animals from experimental group I received 20% ethanol for drinking (ad libitum), animals from experimental group II--cephalexin in the dose of 42 mg/24 h, animals from experimental group III--cephalexin and ethanol in mentioned doses. After 10 days animals were decapitated and specimens of the stomach were taken from the greater curvature.

Histological and morphometrical examinations of suprarenal glands in rats after experimental administration of atorvastatin and ethanol.

The experiment was carried out on Wistar rat males weighting about 250 g. Animals from control group I received water and standard granulated fodder ad libitum. Animals from control group II received 20% ethanol instead of water.

Histological and ultrastructural investigations of placenta villi in intrauterine growth restriction of fetuses (IUGR).

The investigations were carried out on five placentas derived from normal pregnancies and on the five placentas derived from the pregnancies with intrauterine growth restriction (IUGR) of fetuses. Semithin sections were stained with methylene blue and azure and estimated by light microscope. Ultrathin sections were stained according to the Reynold's method and estimated by the electron microscope.
