The article deals with the information about effect of saline stress factors on some physiological parameters medium-fiber cotton varieties. According to results study experiments, Bukhara-8 and Bukhara-102 varieties have a high level resistance stress. degree adaptation in soil salinity arid unfavorable environmental conditions is higher than Bukhara-10 Sultan, Andijan-35 Variations value stud...

Experiments were performed in C57BL/6J male mice to determine the effects of acetylcholinesterase (AChE) inhibitor pyridostigmine bromide (PB) and stress on cardiovascular function, structure, and apoptosis. Mice were studied for seven days under the following conditions: Controls (osmotic minipump with saline), PB (10 mg/kg/day, minipumps), shaker stress (45 stressors/day, minipump with saline...

BACKGROUND Mental stress is a risk factor for atherosclerosis and may precipitate myocardial ischemia and infarction. Because endothelial dysfunction is an early manifestation of atherosclerosis, we investigated the impact of mental stress on endothelial function. Methods and Results- The effects of a 3-minute mental stress task on endothelium-dependent vasodilation were studied in healthy subj...

Andrés, Rosa, Octavi Martı́, and Antonio Armario. Direct evidence of acute stress-induced facilitation of ACTH response to subsequent stress in rats. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R863–R868, 1999.—To determine the role of glucocorticoids in the appearance of the facilitatory effect of stress on the ACTH response to a subsequent stress, sham-operated (Sham) rats ...

To elucidate the mechanisms underlying tolerance to saline-alkaline stress in two rice genotypes, Dongdao-4 and Jigeng-88, we exposed them to medium supplemented with 10 mM Na2CO3 and 40 mM NaCl (pH 8.5). Dongdao-4 plants displayed higher biomass, chlorophyll content, and photosynthetic rates, and a larger root system than Jigeng-88 under saline-alkaline conditions. Dongdao-4 had a higher shoot...

A non-sodic, non-saline sandy loam soil was salinized to anion-cation ratios similar to those naturally occurring in Iraq and California. The interactions of saline soils (conductivities 4, 8, 12 and 16 mmhos/cm) with a moderately salt-tolerant plant (Lycopersicon esculentum 'Marimond') and a plant parasitic nematode (Meloidogyne javanica) were investigated. Plant parasitic nematodes were shown...

ethods: Plasma ACTH levels were measured after restraint stress in 19 male monkeys pretreated with saline or hydrocortisone. Monkeys ere then randomized to an undisturbed control condition or intermittent social separations followed by new pair formations. After 17 onths of exposure to the intermittent social manipulations, restraint stress tests were repeated to determine test/retest correlati...

The effects of intracerebroventricular (i.c.v.) administration of 0-adrenergic receptor antagonists (d,/-propranolol or timolol, 30 /xg in 2 fiL of isotonic saline) on the increased renal sympathetic nerve activity and decreased urinary sodium excretion (UNaV) responses to stressful environmental stimulation (air jet to head) in conscious spontaneously hypertensive rats (SHR) were examined. Bef...

Intraperitoneal administration of hypertonic saline is a potent stimulus to the "stress" responsive hypophysiotrophic parvicellular neurons of the hypothalamic paraventricular nucleus (PVN), as well as to magnocellular neurons of the hypothalamo-neurohypophysial system. Precise identification of the pathways gating information about the "stress" of intraperitoneal hypertonic saline to the PVN h...

OBJECTIVE Volume replacement in septic patients improves hemodynamic stability. This effect can reduce the inflammatory response. The objective of this study was to evaluate the effect of 7.5% hypertonic saline solution versus 0.9% normal saline solution for volume replacement during an inflammatory response in endotoxemic rats. METHODS We measured cytokines (serum and gut), nitrite, and lipi...
