to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...

Nitric oxide (NO) or NO-generating compounds like sodium nitroprusside (SNP) increase cellular levels of cGMP and produce S-nitrosylation of glyceraldehyde-3-phosphate dehydrogenase [GAPDH; D-glyceraldehyde-3-phosphate:NAD+ oxidoreductase (phosphorylating), EC 1.2.1.12]. In search of a reagent that could discriminate between these two effects, we used the sesquiterpene antibiotic koningic acid,...

The formation of propagules is the critical stage for transmission pathogenic fungus Stemphylium eturmiunum. However, how development these regulated remains to be fully understood. Here, we show that nitric oxide (NO) necessary reproduction in S. eturmiunum.Application NO scavenger carboxy-CPTIO (cPTIO) or soluble guanylate cyclase (sGC) inhibitor NS-2028 abolishes formation, which was increas...

The present work reveals the beneficial role of sodium nitroprusside (SNP; NO donor concentration: 50 and 100 µM) in mitigation water stress accompanied by a reduction viral disease incidence tomato plants subjected to deficit irrigation. were grown under two irrigation regimes: well-watered (WW; irrigated after depletion 55–60% available soil water) (WD; 85–90% seasons 2018 2019. results indic...

BACKGROUND Pulmonary hypertension is associated with a worse prognosis after cardiac transplantation. The pulmonary hypertension reversibility test with sodium nitroprusside (SNP) is associated with a high rate of systemic arterial hypotension, ventricular dysfunction of the transplanted graft and high rates of disqualification from transplantation. OBJECTIVE This study was aimed at comparing...

In order to study the effects of 200 μmol/L SNP for 1, 3, 5, 7 d on growth and enzymes related nitrogen metabolism under low temperature stress 12/6℃, day/night, explore feasibility exogenous SNP regulating melon ( Cumumis melo.  L) seedlings, seedlings were used as experimental materials cultivated by substrate culture method. NO donor sodium nitroprusside (SNP...

Trimetaphan nitroprusside (TNP) is a new potent hypotensive agent developed to induce and maintain decreases in arterial pressure unaccompanied by resistance. This study investigated its properties and compared them with those of sodium nitroprusside (SNP) in anaesthetized greyhounds. The mean dose response to TNP was obtained by measuring haemodynamic changes in five dogs. With increasing dose...

Brain cytochrome oxidase activity was measured after the in vitro addition of potassium cyanide (KCN) or sodium nitroprusside (SNP). Activity of cytochrome oxidase was sensitive to KCN; however, this activity was unaffected by SNP. In SNP- and KCN-treated animals brain cytochrome oxidase activities were measured. At 3 min after SNP injection, inhibition of the enzymatic activity was the same as...
