[Effect of phenobarbital stimulation on morphological and cytoenzymatic changes in the liver of benzene intoxicated rats (author's transl)]. 1976

J J Jonek, and M Kamiński, and H Grzybek, and B Panz, and B Gruszeczka

The experiments were carried out on male Wistar-Rats. They were divided into 2 groups. The rats of the control groups were treated to Phenobarbital intraperitoneally for 3 consecutive days. The animals of the experimental group were additionaly injected with Benzen intraperitoneally on the 4th day of experiment. It has been found that Phenobarbital brought about the formation of 2 types of bright and dark cells in the liver. The action of Phenobarbital is carried on by Benzene. The authors discuss morphological and functional evaluation of bright and dark cells from the point of view of stimulating action of Phenobarbital as well as the course of Benzene biotransformation in liver cells.

D010634 Phenobarbital A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.

D004721 Endoplasmic Reticulum A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH). (King & Stansfield, A Dictionary of Genetics, 4th ed) Ergastoplasm,Reticulum, Endoplasmic
D005952 Glucose-6-Phosphatase An enzyme that catalyzes the conversion of D-glucose 6-phosphate and water to D-glucose and orthophosphate. EC 3.1.3.9. Glucosephosphatase,Glucose 6-Phosphatase,Glucose-6-Phosphate Phosphohydrolase,Glucose 6 Phosphatase
D006651 Histocytochemistry Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods. Cytochemistry
D000251 Adenosine Triphosphatases A group of enzymes which catalyze the hydrolysis of ATP. The hydrolysis reaction is usually coupled with another function such as transporting Ca(2+) across a membrane. These enzymes may be dependent on Ca(2+), Mg(2+), anions, H+, or DNA.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001554 Benzene Toxic, volatile, flammable liquid hydrocarbon byproduct of coal distillation. It is used as an industrial solvent in paints, varnishes, lacquer thinners, gasoline, etc. Benzene causes central nervous system damage acutely and bone marrow damage chronically and is carcinogenic. It was formerly used as parasiticide. Benzol,Benzole,Cyclohexatriene
