“…In the previous studies reported that L-NNA decreases the activities of antioxidant enzymes and enhances lipid peroxidation (29). In accordance with previous studies, it was observed that 150 mg/kg dose of ISO induced a myocardial damage and significantly altered biochemical parameters and antioxidant enzyme activities in the present study (13).…”

Objective: The aim of this study is to investigate the effects of caffeic acid phenethyl ester (CAPE) on isoproterenol (ISO)-induced myocardial injury in hypertensive rats. Methods: Rats were divided into 4 groups (n=29):n=7) and L-NNA+ISO+CAPE (L-NNA+ISO + caffeic acid phenethyl ester) group (n=6). ISO (150 mg/kg/day) was given intraperitoneally (i.p.) once a day for 2 consecutive days (at the 12 th and 13 th days of L-NNA treatment). NG-Nitro-L-arginine (L-NNA) was given orally (25 mg/kg/ day) in drinking water for 14 days. CAPE (10 μmol/kg/day) was given (i.p.) for 7 days after the first week. Systolic blood pressure (SBP) was evaluated by the tail-cuff method and biochemical analysis were performed using an autoanalyzer and a spectrophotometer. Results: SBP in all L-NNA-treated groups was found to be increased at seventh day. AST and LDH levels in LNNA+ISO group were significantly increased compared to control (AST: 125±5 vs. 105±2; LDH: 861±154 vs. 571±46 U/L respectively) (p<0.05). Also, ISO caused to extensive necrosis and mononuclear cell infiltration in hypertensive rat myocardium. CAPE application reversed the enhanced AST and LDH levels as well as the extensive necrosis and the mononuclear cell infiltration in LNNA+ISO+CAPE group compared LNNA+ISO. Conclusion: According to our findings, it might be suggested that CAPE may be a favorable agent to protect the hypertensive myocardium from the injury induced by isoproterenol via mechanisms such as the induction of the antioxidant enzymes and the inhibition of lipid peroxidation.

“…6 and 7). NO has been suggested to increase the activities of antioxidant enzymes and up-regulate the expressions of the antioxidant genes in plants (Zhou et al, 2005;Zhang et al, 2007). It is well known that the antioxidant defense system plays vital roles in plants' tolerance to stressful conditions (Guan et al, 2009;Gill and Tuteja, 2010).…”

Polyamines (PAs) and nitric oxide (NO) are vital signals in modulating plant response to abiotic stress. However, to our knowledge, studies on the relationship between NO and PAs in response to cold stress in tomato are limited. Accordingly, in this study, we investigated the effects of putrescine (Put) and spermidine (Spd) on NO generation and the function of Spd-induced NO in the tolerance of tomato seedling under chilling stress. Spd increased NO release via the nitric oxide synthase (NOS)-like and nitrate reductase (NR) enzymatic pathways in the seedlings, whereas Put had no such effect. Moreover, H 2 O 2 might act as an upstream signal to stimulate NO production. Both exogenous NO donor (sodium nitroprusside (SNP)) and Spd enhanced chilling tolerance in tomato, thereby protecting the photosynthetic system from damage. Compared to chilling treatment alone, Spd enhanced the gene expressions of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX), and their enzyme activities in tomato leaves. However, a scavenger or inhibitor of NO abolished Spd-induced chilling tolerance and blocked the increased expression and activity due to Spd of these antioxidant enzymes in tomato leaves under chilling stress. The results showed that NO induced by Spd plays a crucial role in tomato's response to chilling stress.

“…Nitric oxide is effective in enhancing growth and development from seed germination to the adult stage (Desikan et al, 2004). It also promotes flowering and hormonal responses (Zhou et al, 2005). However, exogenous application of NO has been reported to enhance relative water content, chlorophyll, and proline contents of wheat plants under arsenic-induced oxidative stress (Hasanuzzaman et al, 2012).…”

A study was conducted to assess whether foliar-applied nitric oxide (NO) could alleviate the adverse effects of salt stress on wheat (Triticum aestivum L.). Four sodium nitroprusside levels (control [water spray] and 0.05, 0.10, and 0.15 mM) were sprayed as a donor of NO on the leaves of cultivar S-24 plants grown under nonsaline and saline conditions (150 mM NaCl). Data for growth and yield, chlorophyll contents, activities of antioxidants, and concentrations of mineral nutrients were recorded. Root-medium salinity adversely affected shoot and root dry weight, shoot length, and yield attributes of the wheat plants while it enhanced the activities of antioxidants, proline accumulation, and concentrations of shoot and root Na + and Cl -. Foliar-applied NO improved growth of only nonstressed plants. Exogenously applied NO enhanced the activities of antioxidant enzymes (superoxide dismutase [SOD], peroxidase [POD], and catalase [CAT]) and levels of soluble proteins and proline, in both stressed and nonstressed wheat plants. Overall, exogenous application of NO enhanced chlorophyll contents; activities of CAT, POD, and SOD; and levels of soluble proteins and total free proline in the salt stressed wheat plants. The exogenous application of NO had a protective role against salt-induced oxidative damage by enhancing the activities of antioxidant enzymes, thereby improving plant growth under saline stress.
