hypotension/phosphatase

The mRNA abundance of several hepatic glycolytic and gluconeogenic enzymes and blood hormone concentrations were determined in hemorrhagic hypotension-induced rats before and after resuscitation with lactated Ringer's. Northern blot analysis of total liver RNA after 30 min of hemorrhage showed

The thiazide-sensitive NaCl cotransporter (NCC) of the renal distal convoluted tubule (DCT) controls ion homeostasis and arterial BP. Loss-of-function mutations of NCC cause renal salt wasting with arterial hypotension (Gitelman syndrome). Conversely, mutations in the NCC-regulating WNK kinases or

Mitogen-activated protein kinase phosphatase-1 (MKP-1) is essential in limiting the proinflammatory response to lipopolysaccharide (LPS). We hypothesized that Mkp-1(-/-) mice would respond to low-dose LPS with a fall in blood pressure due to augmented expression of inducible nitric oxide (NO)

Septic shock is a leading cause of morbidity and mortality. However, genetic factors predisposing to septic shock are not fully understood. Excessive production of proinflammatory cytokines, particularly tumor necrosis factor (TNF)-alpha, and the resultant severe hypotension play a central role in

Inducible nitric-oxide (NO) synthase (iNOS) plays a critical role in the eradication of intracellular pathogens. However, the excessive production of NO by iNOS has also been implicated in the pathogenesis of septic shock syndrome. Previously, we have demonstrated that mice deficient in

Effects of corticosteroids and surgical stress on hepatic morphologic features and enzymes were studied in 18 mature dogs of mixed breeding: group 1, control (n = 3); group 2, dexamethasone (n = 5); group 3, dexamethasone and surgery (n = 5); and group 4, surgery (n = 5). Dexamethasone (2.2 mg/kg of

Mitogen-activated protein (MAP) kinase cascades are crucial signal transduction pathways in the regulation of the host inflammatory response to infection. MAP kinase phosphatase (MKP)-1, an archetypal member of the MKP family, plays a pivotal role in the deactivation of p38 and JNK. In vitro studies

Acid phosphatase, alkaline phosphatase and acid cathepsin activity increased in the subcellular fraction of the grey matter of dog brain in proportion to the duration of compression ischemia, particularly in the postmitochondrial supernatant. An increase in the alkaline phosphatase and of the acid

We examined the effect of hemorrhagic hypotension on cerebral blood flow and perfused capillaries in newborn pigs, 2-10 days old. Cerebral blood flow was measured by using radioactive microspheres, perfused capillaries were determined by infusing a plasma marker, fluorescein isothiocyanate (FITC) -

Recent studies have reported a correlation between dementia and low blood pressure. How hypotension is associated with the increased risk of Alzheimer's disease (AD) remains unclear. Here we show that one month treatment of losartan, an angiotensin II type 1 (AT1) receptor antagonist, causes chronic

In a study of 4-hr hemorrhagic hypotension in dogs, the plasma levels of the lysosomal enzymes, cathepsin (CATH) and acid phosphatase (AP) showed early and progressive increases in activity. The plasma levels of the intestinal fraction of alkaline phosphatase (IAkP) and aspartate aminotransferase

Rats which had approximately 25-30% of their calculated blood volume removed were exposed to halothane (1%) or enflurane (2%) in 33% oxygen for 30 min. Hepatic function was evaluated by determining, at various time intervals, serum activities of glutamic-oxalacetic and glutamic-pyruvic transaminase,

To determine whether non-invasive measurement of brain electrical activity can predict ischemic brain damage, we recorded the electroencephalogram (EEG) and somatosensory- (SEP) and auditory- (AEP) evoked potentials before, during, and after trimethaphan-induced profound arterial hypotension in

OBJECTIVE To evaluate the possible renal and hepatic toxicity of tepoxalin in dogs exposed to hypotension during isoflurane anesthesia. METHODS Prospective, randomized experimental study. METHODS Twenty adult mixed-breed dogs, weighing 18.8 ± 2.8 kg. METHODS The animals received 10 mg kg(-1)
