Nitric oxide (NO) is involved in numerous physiological and stress responses in higher plants. Tomato is one of the most important vegetable crops in the world and previously it has been reported that salinity induced an oxidative stress affecting its redox and NO homeostasis. Using tomato plant exposed to 120 mM NaCl, it was studied whether the exogenous application of NO could ameliorate the ...

Thyroid hormones from the thyroid gland are necessary for the normal development of body organs. It was demonstrated that NO participates in the regulation of thyroid function. NO brings about oxidation reactions which will produce free radicals, and can start chain reactions that damage cells. This leads to the production of ROS. These oxidants can damage cells by starting chemical chain react...

sulfur mustard (sm) has been identified as an important chemical weapon. during the iran-iraq war of 1980-88, the extensive usage of sm against iranian civilians and military forces was proven. this agent has been shown to cause severe damage mainly in the skin, eyes, lungs,  and  respiratory  tract  in  iranian  veterans.  the  most  common  disease  is bronchiolitis obliterans (bo)). sm incre...

BACKGROUND Extracellular superoxide dismutase (ECSOD) protects nitric oxide (NO) bioavailability by decreasing superoxide levels and preventing peroxynitrite generation, which is important in maintaining renal blood flow and in preventing acute kidney injury. However, the profile of ECSOD expression after sepsis is not fully understood. Therefore, we intended to evaluate the content and gene ex...

•2 Excessive production and/or inadequate removal of reactive oxygen species, especially superoxide anion (O ), have been implicated 2 in the pathogenesis of many cardiovascular diseases, including atherosclerosis, hypertension, diabetes, and in endothelial dysfunction by •2 decreasing nitric oxide (NO) bioactivity. Since the vascular levels of O are regulated by the superoxide dismutase (SOD) ...

OBJECTIVE To study the focal cerebral ischemia/reperfusion (I/R) injury induced by a middle cerebral artery occlusion (MCAO), and the effects of Yulangsan (YLS) polysaccharide on this injury. METHODS This study took place in the Pharmacology Research Laboratory at Guangxi Medical University, China, between March and May 2007. Two hundred and forty rats were randomly divided into I/R group, sh...

The effect of nano silica (50 mL L−1) and melatonin (75 µM) individually or in combination foliar applications on the morphophysiological, biochemical yield properties pea plants under salinity stress conditions was evaluated. Salt caused a remarkable decrease growth characteristics; for example, plant dry weight, height, number flowers plant−1, pods weight 100 green seeds protein concentration...

background & aim:  ulcer index is one of the most common diseases among people. current therapies include acid secretion inhibitors which have various side effects. herbal medicines are considered as adjuvant therapy for this disease. hydroalcoholic extract of thymus daenensis has various components such as flavonoids which contribute to gastroprotection. experimental: 35 sprague dawley rat...

Wistar rats were given a diet with 8% sodium chloride to induce hypertension and subsequently sacrificed. Glycine max powder was used reduce atenolol’s side effects during the trial. Thirty divided into five groups tested over eight weeks. Rats’ blood pressure (BP) measured tail-cuff NIBP monitor. Biochemical markers like TG, TC, HDL, LDL, VLDL, alanine transferase, aspartate lipid peroxide (LP...
