Although the pathogenesis of sperm granulomas is complicated, the leakage of spermatozoa into extraluminal tissues is regarded as a crucial event. It has been previously shown that pubertal rats injected with L-cysteine develop interstitial edema followed by sperm granulomas in the epididymis. In

Ischemic brain is highly vulnerable to free radicals mediated secondary neuronal damage especially mitochondrial dysfunctions. Present study investigated the neuroprotective effect of S-allyl L-cysteine (SAC), a water soluble compound from garlic, against cerebral ischemia/reperfusion (I/R)-induced

Hydrogen sulfide, which can be generated in the central nervous system from the sulfhydryl-containing amino acid, L-cysteine, by cystathionine-β-synthase, may exert protective effects in experimental subarachnoid hemorrhage; however, the mechanism underlying this effect is unknown. This study

Inhibition of Na+,K+-ATPase activity causes edema and cell death in central nervous system. We determined the in vitro effects of galactose-l-phosphate (Gal-1-P), galactitol (Galtol) and galactose (Gal) (mix A = classical galactosaemia) or Galtol and Gal (mix B = galactokinase deficiency

We investigated the histopathological effects of excess L-cysteine on the male rat reproductive tract during sexual maturation. Male 6-week-old Sprague-Dawley rats were injected intraperitoneally daily with L-cysteine, 1,000 mg/kg body weight, for 1, 2, 3, and 4 weeks. L-Cysteine-treated rats

N-acetyl-S-farnesyl-L-cysteine (AFC), a modulator of G protein and G-protein coupled receptor signaling, inhibits neutrophil chemotaxis and other inflammatory responses in cell-based assays. Here, we show topical AFC inhibits in vivo acute inflammation induced by

l-Cysteine is a semi-essential amino acid and substrate for cystathionine-β-synthase (CBS) in the central nervous system. We previously reported that NaHS, an H2S donor, significantly alleviated brain damage after subarachnoid hemorrhage (SAH) in rats. However, the potential therapeutic value of

Oxidative stress caused by ammonia toxicity is known to play a key role in the pathogenesis of hepatic encephalopathy (HE). The present study was designed to evaluate the protective effect of N-acetyl-L-cysteine (NAC) supplementation in a bile duct ligation (BDL)-induced model of HE. Three weeks

Cyclophosphamide (CP) is a complex multifaceted developmental toxicant, with mechanisms of teratogenesis thought to include production of excessive reactive oxygen species (ROS). N-acetyl-L-cysteine (NAC) is a powerful antioxidant that may decrease the toxicity of certain anticancer drugs, such as

BACKGROUND Wound healing and chronic wounds are serious public health issues. While wounds heal, cellular stores of antioxidants are depleted. d-ribose-l-cysteine (DRLC) is a precursor to the antioxidant glutathione. The effect of oral supplementation with DRLC on wound healing was studied in

This study was conducted to investigate the possible protective role of thymoquinone (TQ) and l-cysteine on the reproductive toxicity of male rats induced by cadmium chloride (CdCl2). Forty rats were divided into four even groups. The first group served as untreated control. The second, third and

Neonatal hypoxic-ischemic (HI) injury is a major cause of neonatal death and neurological dysfunction. H2S has been shown to protect against hypoxia-induced injury and apoptosis of neurons. L-Cysteine is catalyzed by cystathionine-β-synthase (CBS) in the brain and sequentially produces endogenous

The aim of this study was to assess the effects of L-cysteine (Cys) (7 mg/kg) and N-acetyl-L-cysteine (NAC) (50 mg/kg) in the rat liver caused by subchronic i.p. application of methionine (Met) (0.8 mmol/kg) during 21 days. Malondialdehyde (MDA) concentration, glutathione content (GSH), catalase

In this brief review the antioxidative actions of melatonin are summarized and they are discussed relative to several models of oxidative neurotoxicity. Melatonin is a ubiquitously acting antioxidant. It has been shown to scavenge the hydroxyl radical, peroxyl radical, singlet oxygen and the

BACKGROUND Multiple organ failure is the major mortality-related complication in severe acute pancreatitis. Endothelial barrier injury may be involved in its pathophysiology. METHODS The present study evaluated alterations in endothelial barrier integrity in different organs/tissues 12 h after
