Free radicals can cause various kinds of degenerative diseases and skin aging. be neutralized with an enzymatic antioxidant, namely superoxide dismutase (SOD). One the plants that has high SOD activity is salam (Syzygium polyanthum). The aim this study was to determine crude extract bay leaves precipitated ammonium sulfate salt at concentrations 25, 50, 75%. began plant determination, enzyme ex...

Idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD) are thought to involve lung injury induced by reactive oxygen species (ROS), in particular superoxide anion. The enzyme, superoxide dismutase (SOD) catalyses the dismutation of superoxide anion to hydrogen peroxide. Lecithinized SOD (PC-SOD) has overcome a number of previous clinical limitations of SOD, includi...

The brain's anti-oxidant response to highly elevated oxygen (O2) partial pressures is poorly understood. In this study we hypothesized that hyperbaric O2 (HBO2) would stimulate superoxide dismutase (SOD) transcription in the oxidative stress-sensitive rat hippocampus and measured the time course and extent of the changes in hippocampal mRNA for all three SOD isoforms and total SOD enzyme activi...

The enzyme activity of superoxide dismutase was improved in the pyrogallol autoxidation system by about 27%, after interaction between hydroxypropyl-β-cyclo-dextrin and superoxide dismutase. Fluorescence spectrometry was used to study the interaction between hydroxypropyl-β-cyclodextrin and superoxide dismutase at different temperatures. By doing this, it can be found that these interactions in...

background: it is well known that the development of brain oxidative stress is one of the most serious complications of arterial hypertension that evokes brain tissue damage. the aim of this study was to examine the effects of atorvastatin treatment (20 mg/kg/day), as an antioxidant, to prevent the brain tissue oxidative stress in the hypertensive (htn) rats. methods: experiments were performed...

Background: Diazinon (DZN) is an organophosphate pesticide commonly used for pest control in agriculture. It may engender a variety of negative effects in non-target species, including humans and animals. The objective of the present study was to evaluate the ameliorative properties of captopril (CAP), as a thiol containing an angiotensin-converting enzyme inhibitor, against DZN-induced oxidati...

background superoxide dismutase is an important mammalian antioxidant that is found in all tissues and its role in periodontal disease is emphasized. chronic periodontitis is the most common form of periodontal disease that causes destruction of connective tissue and bone around the teeth. one way to help the treatment of periodontal disease is use of oral supplements such as chlorhexidine, whi...
