The mesangial cell occupies a central position in the renal glomerulus. It has characteristics of a modified smooth muscle cell, but is also capable of a number of other functions. Among these are generation of prostaglandins (PGs) and mediators of inflammation; production and breakdown of basement membrane and other biomatrix material; synthesis of cytokines; and uptake of macromolecules, incl...

Bovine lactic acidosis syndrome is associated with large increases of lactic acid in the rumen, which result from diets that are high in ruminally available carbohydrates, or forage that is low in effective fiber, or both. The syndrome involves two separate anatomical areas, the gastrointestinal tract and body fluids, and is related to the rate and extent of lactic acid production, utilization,...

BACKGROUND/AIMS Several polymorphisms of vasoactive hormones have been implicated in hypertension. Erythropoietin (EPO) interacts with vasoactive substances, such as angiotensin II. Previously detected single nucleotide polymorphisms in the hypoxia-responsive element of EPO might be associated with hypertension and hypertensive end organ damages. METHODS 400 hypertensive patients and 200 age-...

J. Bacteriol. 90:1001-1006. 1965.-The transient phase of increased susceptibility to bacterial infection in mice provoked by prior administration of small doses of endotoxin was investigated for po...

The present investigation was undertaken to see if any of the naturally occurring vasoactive substances was likely to act as a mediator for the pulmonary vasoconstrictor response to acute alveolar hypoxia. Rats were treated with agents that deplete local stores of vasoactive amines or inhibit their synthesis. Lungs from these animals were isolated, ventilated, and perfused with homologous blood...

This review discusses the concept that nitric oxide synthase (NOS) may orchestrate both the inflammatory response to the renal allograft and anti-inflammatory defense in the graft itself. NO is produced by endothelial, epithelial, as well as inflammatory cells. In the setting of transplantation, the endothelium is the first lining to be subjected to the early response to injury. In turn, activa...

introduction: children may be intentionally or unintentionally exposed to any substance. substance poisoning is one of the most important emergency interventions in children that cause a great number of deaths each year. regarding the importance of this issue and recent increase in number of poisoning cases, a study with the aim of investigating cases of substance poisoning and factors involved...

Objective: comparative analysis of the use PiCCO monitoring for correction intensive care in patients with multiple organ dysfunction syndrome (MODS) after abdominal and cardiac surgery.
