Sea cucumbers saponins are triterpenoid glycosides which exert beneficial biomedical effects. This study was performed to assess the effect of saponin extracted from sea cucumber Holothuria leucospilota (H. leucospilota) on maturation of mice oocytes and granulosa cells. The germinal vesicles oocytes were collected from 6-8 weeks old Naval Medical Research Institute (NMRI) mice ovaries, randoml...
Chronic renal failure is a progressive loss of renal function over a period of months or year and Hemodialysis is a suitable treatment which is preferably given to the chronic renal failure ernment RF) . Who are not to undergo renal transplantation therapy. This study was carried out to observe the immediate effect of oxidative stress and inflammation during hemodialysis . In the present study ...
Objective: To prepare pulmonary surfactant-superoxide dismutase (PS-SOD) Liposomes and analyze the biological characteristics of them. Methods: To prepare PS-SOD Liposomes with rotary evaporation method and analyze the formulation and bioactivity of them, including shape, size, encapsulating ratio, antioxidant activity and surface tension. Results: The PS-SOD Liposome is a kind of ivory white s...
Nitric oxide is involved in abscisic acid-induced antioxidant activities in Stylosanthes guianensis.
Previous studies suggest that abscisic acid (ABA) stimulates the activities of antioxidant enzymes under normal and chilling temperature and enhanced chilling resistance in Stylosanthes guianensis. The objective of this study was to test whether nitric oxide (NO) is involved in the ABA-induced activities of the antioxidant enzymes in Stylosanthes guianensis due to its nature as a second messeng...
introduction : recurrent aphthous stomatitis (ras) is a common disease with unknown etiology and no treatment. the purpose of this study is to assess the relationship between serum antioxidants level and clinical manifestation. change in antioxidant level can lead inflammatory reaction through oxidative stress. materials & methods : a total 50 patients were selected for this cross sectional stu...
OBJECTIVE To study the biological effects of nanoscale copper oxide (nCuO), zinc oxide (nZnO), cerium dioxide (nCeO2) and their mixtures on Carassius auratus. METHODS Juvenile fish (Carassius auratus) were exposed to aqueous suspensions of nCuO, nZnO, and nCeO2 (alone and in mixtures) at concentrations of 20, 40, 80, 160, and 320 mg/L. The biomarkers-acetylcholinesterase (AChE) in brain, sodi...
Inducible nitric oxide synthase (iNOS) and superoxide dismutase (SOD) play an important role in the pathology of ischemia-reperfusion. This study sought to determine if the proinflammatory effects of complement modulate iNOS and SOD in the rat after gastrointestinal ischemia and reperfusion (GI/R). An inhibitory or noninhibitory anti-complement component 5 (C5) monoclonal antibody (18A or 16C, ...
Kudingcha is a traditional Chinese tea, and insect tea is a special drink produced by the metabolism of insect larvae using the raw Kuding tea. Insect tea polyphenols (ITP) and its raw tea (Kuding tea) polyphenols (KTP) are high-purity polyphenols extracted by centrifuge precipitation. The present study was designed to compare the antioxidative effects of insect tea polyphenols (ITP) and its ra...
Oxidative Stress is implicated as one of the primary factors that contribute to the development of neurodegenerative diseases like Alzheimer's Disease, Parkinsonism and neurological conditions like epileptic seizures, stroke, brain damage, neurotrauma etc. The increased formation and release of oxygen free radicals coupled with the rather low antioxidative potential of the central nervous syste...
Recent work has demonstrated that inhibition of nitric oxide production with various nitric oxide synthesis inhibitors (L-NAME, L-NMMA) initiate leukocyte adhesion to postcapillary venules. The objective of this study was to elucidate the mechanism (or mechanisms) that promote the L-NAME-induced leukocyte response. Intravital microscopy was used to examine 25-40 microns venules in the rat mesen...
