[ 1 ] - Protective effects of vitamin B6 alone and in combination with L-cysteine and NaHS on ethanol and indomethacin-induced gastric lesions in mice
Objective(s): This study was undertaken to investigate the protective effects of vitamin B6, cofactor for cystathionine-γ lyase and cystathionine-β synthase (producers of H2S), alone and in combination with L-cysteine, H2S precursor, on indomethacin-, and ethanol-induced gastric lesions in male NMRI mice. Materials and Methods: Fasted male NMRI mice were randomly assigned into 12 groups (7 in ...
[ 2 ] - The protective activity of noscapine on renal ischemia–reperfusion injury in male Wistar rat
Objective(s):Bradykinin is a part of the kinin-kallikreinsystem which is involved in ischemia-reperfusion injury via B1 and B2 receptors.Noscapine is a non-competitive antagonist of bradykinin receptors. Noscapine has been reported to to be able to protect some organs against ischemia-reperfusion injury but its effect on renal ischemia-reperfusion injury (RIR) in rats is unknown. Therefore, the...
[ 3 ] - Bronchodilatory Effect of Hydrogen Sulfide in Rat
Objective(s) The aims of present study were to elucidate the effect of NaHS as a H2S donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. Materials and Methods Tracheal rings from male adult Wistar rats were isolated and mounted in an organ bath containing Krebs–Henseleit solution under 1.5 g resting tension and contractions were recorded isom...
[ 4 ] - Progesterone and Cilostazol Protect mice pancreatic islets from oxidative stress induced by hydrogen peroxide
Abstract Reactive oxygen species and oxidative stress impair β-cell function and reduce insulin secretion. It has been shown that progesterone and cilostazol possess antioxidant properties. The present study was aimed to investigate in vitro pretreatment effect of progesterone and cilostazol on insulin secretion as well as their protective effects against hydrogen peroxide-induced oxidative str...

Abstract Reactive oxygen species and oxidative stress impair β-cell function and reduce insulin secretion. It has been shown that progesterone and cilostazol possess antioxidant properties. The present study was aimed to investigate in vitro pretreatment effect of progesterone and cilostazol on insulin secretion as well as their protective effects against hydrogen peroxide-induced oxidative str...
[ 6 ] - Duodenal acidification stimulates gastric H2S release through upregulating mRNA expression of cystathionine gamma lyase
Introduction: It has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of H2S, but till now the effect of duodenal acidification on gastric H2S release has not been investigated. Therefore, the present study designed to evaluate the effects of duodenal acidification on gastric H2S release and level of mRNA expression of cys...
[ 7 ] - Effects of endogenous production and exogenous administration of H2S on gastric acid secretion in rats
Introduction: Recently, hydrogen sulfide has been introduced as the third gas that acts as a transmitter. It has many physiological and pharmacological roles in the human body. The aim of the present study was to investigate the effect of exogenously administered and endogenously produced H2S on the basal and distention-induced gastric acid secretion in rats. Methods: Forty-nine male Wistar...
[ 8 ] - Effect of crocin on cardiac antioxidants, and hemodynamic parameters after injuries induced by hepatic ischemia-reperfusion in rats
Objective(s): This research aimed to test the impact of liver ischemia/reperfusion (IR) insult on the activity of antioxidant enzymes, functional enzymes, histological, and hemodynamic parameters of heart, as well as protective function of crocin on these variables in rats. Materials and Methods: Thirty two rats were randomly assigned into 4 experimental groups (8 rats in each). I: sham-oper...
[ 9 ] - Gallic acid protects the liver in rats against injuries induced by transient ischemia-reperfusion through regulating microRNAs expressions
Objective(s): Gallic acid (GA) is a highly effective antioxidant, which its beneficial effects are well known, but its impact on expression of microRNAs (miRs) following hepatic ischemia-reperfusion (I/R) is not well recognized. Therefore, the current research was designed to specify the beneficial effect of GA on miRs (122 and 34a), liver functional tests, and histopathological alterations bey...
[ 10 ] - p-Coumaric acid protects cardiac function against lipopolysaccharide-induced acute lung injury by attenuation of oxidative stress
Objective(s): Acute lung injury (ALI) has a high mortality rate and is characterized by damage to pulmonary system giving rise to symptoms such as histological alteration, lung tissue edema and production of proinflammatory cytokine. p-Coumaric acid (p-CA), as a phenolic compound, that is found in many types of fruits and vegetables has been reported to exhibit a thera...
[ 11 ] - Protective effects of gallic acid on cardiac electrophysiology and arrhythmias during reperfusion in diabetes
Objective(s): Gallic acid (GA), a potent anti-oxidant, plays an important role in reducing diabetic induced cardiac disorders. Therefore, the present investigation was purposed to determine the beneficial effect of GA in cardiac arrhythmias during reperfusion in diabetes induced by alloxan. Materials and Methods: Male Sprague-Dawley rats...
[ 12 ] - Does p-coumaric acid improve cardiac injury following LPS-induced lung inflammation through miRNA-146a activity?
Objective: In cardiovascular diseases, inflammatory response plays an important role and affects heart function. As a flavonoid compound, p-coumaric acid (pCA), commonly exists in many fruits and vegetables and has a therapeutic effect on inflammatory diseases due to its anti-inflammatory properties. The purpose of the present study was to investigate pCA anti-inflammatory effect and the miRNAs...
[ 13 ] - Does gallic acid improve cardiac function by attenuation of oxidative stress and inflammation in an elastase-induced lung injury?
Objective(s): Cardiovascular disease has an important role in mortality caused by lung injury. Emphysema is associated with impaired pulmonary gas exchange efficiency and airflow limitation associated with small airway inflammation. The aim was to evaluate the interactions between lung injury, inflammation, and cardiovascular disease. Since gallic acid has antioxidant ...
