[Effect of triton WR 1339 on the ultrastructure of liver parenchymal and stromal cells in rats with chronic toxic hepatitis]. 1977

G M Vakulin, and T A Korolenko, and V G Titova, and G S Iakobson

A preliminary injection of triton WR 1339 protectively influenced the chronic toxic CCl4-hepatitis. The ultrastructural peculiarities were close to the normal ones in hepatocytes, in addition to the increased triglyceride rejection from cells by means of autophagy. The revealed stimulation signs of pinocytosis in hepatocytes and the Kupfer cells are accompanied by the activation of the Golgi complex and, probably, by the increased protein catabolism in lysosomes. The signs of phagocytosis increase in the Kupfer cells were determined. It is supposed that the marked ultrastructural peculiarities of liver cells reflect a more effective restoration or a lesser injury under the influence of triton WR 1339.

UI	MeSH Term	Description	Entries
D007728	Kupffer Cells	Specialized phagocytic cells of the MONONUCLEAR PHAGOCYTE SYSTEM found on the luminal surface of the hepatic sinusoids. They filter bacteria and small foreign proteins out of the blood and dispose of worn out red blood cells.	Kupffer Cell,Cell, Kupffer,Cells, Kupffer
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008247	Lysosomes	A class of morphologically heterogeneous cytoplasmic particles in animal and plant tissues characterized by their content of hydrolytic enzymes and the structure-linked latency of these enzymes. The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured or undergoes MEMBRANE FUSION.

D010587	Phagocytosis	The engulfing and degradation of microorganisms; other cells that are dead, dying, or pathogenic; and foreign particles by phagocytic cells (PHAGOCYTES).	Phagocytoses
D010873	Pinocytosis	The engulfing of liquids by cells by a process of invagination and closure of the cell membrane to form fluid-filled vacuoles.	Pinocytoses
D011092	Polyethylene Glycols	Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

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).
