The time course of lesion development in mice induced by a single intraperitoneal (ip) LD50 dose of Pseudomonas aeruginosa slime glycolipoprotein (GLP) was studied. Slime GLP exerted a marked effect on the lungs, liver and kidneys without any microscopic changes in other organs. The first histological lesions were observed in the lungs 7h after ip injection and were characterized by thickening and pleomorphic inflammatory infiltration of the intraalveolar septae leading to focal atelectasis by 28 h. The initial morphological alterations in the liver were observed at 14 h and consisted of balloon degeneration of the hepatocytes, especially around the central veins, leading to fatty change within 21 h and confluent hepatocellular necrosis at 28 h. The kidneys showed hydropic degeneration of the renal tubular epithelial cells at 14 h and frank necrosis by 28 h post ip injection. The kidney and liver lesions were accompanied by a parallel rise in serum levels of blood urea nitrogen and aspartate and alanine aminotransferases.

They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes. Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating

D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D011550 Pseudomonas aeruginosa A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.
