Superoxide dismutase (SOD) is used to manage chronic pain, including neuropathic and inflammatory pain. However, data regarding the clinical effectiveness are conflicting and the neurophysiological mechanism of SOD has yet to be elucidated. The aim of the present study was to investigate whether SOD relieved chronic central pain (CCP) following spinal cord injury (SCI) and the possible underlyi...
The immunohistochemical localization of manganese superoxide dismutase (Mn-SOD), nitric oxide synthase (NOS) and calcium (Ca) binding proteins; calbindin-D28K (Calb) and parvalbumin (Parv), was investigated in the rat hippocampus by using a double immunostaining method and an enzyme histochemical staining method. These substances showed considerable regional immunoreactivities in the hippocampu...
cirrhosis is associated with hyperdynamic circulation, manifesting as increased cardiac output and decreased systemic vascular resistance. the aim of this study was to investigate the effect of cirrhosis on heart apoptosis and involvement of nitric oxide (no) and oxidative stress in the possible altered apoptosis of cirrhotic hearts. twenty-eight days after bile duct ligation, heart tissues wer...
OBJECTIVE Oxidative stress has increasingly been implicated in the development and progression of many vascular diseases. Previous work from our laboratory indicated that peroxynitrite alters vasoactive pathways in endothelial cells, which could potentially reduce vascular relaxation. To test this hypothesis in vivo, we utilized an animal model of endogenous oxidative stress, the CuZn superoxid...
OBJECTIVE This study explored the protective effects of the microRNA-126 (miR-126)-mediated PI3K/Akt/eNOS signaling pathway on human cardiac microvascular endothelial cells (HCMECs) against hypoxia/reoxygenation (H/R)-induced injury and the inflammatory response. METHODS Untreated HCMECs were selected for the control group. After H/R treatment and cell transfection, the HCMECs were assigned t...
PURPOSE The authors determined the levels of the secreted, interstitially located extracellular superoxide dismutase (EC-SOD), the cytosolic copper- and zinc-containing SOD (CuZn-SOD), and the mitochondrial manganese-containing SOD (Mn-SOD) in tears, cornea, sclera, aqueous humor, lens, vitreous body, and retina of the human eye. METHODS SOD enzymatic activity was determined by the direct spe...
Nitroxyl (HNO) may be formed endogenously by uncoupled nitric-oxide (NO) synthases, enzymatic reduction of NO or as product of vascular nitroglycerin bioactivation. The established HNO donor Angeli's salt (trioxodinitrate, AS) causes cGMP-dependent vasodilation through activation of soluble guanylate cyclase (sGC). We investigated the mechanisms underlying this effect using purified sGC and cul...
Andrographis paniculata has been used as a traditional medicine and a predominant constituent in 26 Ayurvedic formulations over the last two decades. Its impact on the male fertility is a controversial from the past few years. In the present study we have investigated the antioxidant enzyme status and the indices of lipid peroxidation in the testis and epididymis of male wistar rats. Male wista...
cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of sesame (sesamum indicum l) seed feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats. male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...
