Background : Quercetin is a member of flavonoids family which can be found in vegetables, fruits, tea and dietary supplements. Quercetin has anti-inflammatory, antibacterial and antioxidant properties. This study evaluated the effect of quercetin on serum antioxidant properties of hind limb ischemia-reperfusion injury in adult rat. Materials and Methods : 72 adult male Wistar rats weighing 250 ...

To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...
objective: electro-magnetic radiation (emr) is emitted from mobile phones. various researches have shown relationships between mobile phone emr exposure to cancer and neurologic damages. this study aims to investigate the effects of mobile phone emr on brain antioxidant enzyme activity and the learning process. methods: rat pups and their dames were exposed to emr for 3 h per day from p2 to p1...
drought is still accounted as a serious agronomic problem and also one of the most important factors contributing to crop yield loss. the effect of sodium silicate (na2sio3, abbreviated as si) was investigated on the four major antioxidant enzyme activities and five other relevant components in two different grapevine cultivars (vitis vinifera l., cvs mish pestan and sahebi, as tolerant and sen...
Angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I (Ang I) to angiotensin II (Ang II). ACE also cleaves the terminal dipeptide of vasodilating hormone bradykinin (a nonapeptide) to inactivate this hormone. Therefore, inhibition of ACE is generally used as one of the methods for the treatment of hypertension. 'Oxidative stress' is another disease state caused by an imb...
Angiotensin converting enzyme (ACE) inhibitors are important for the treatment of hypertension as they can decrease the formation of vasopressor hormone angiotensin II (Ang II) and elevate the levels of vasodilating hormone bradykinin. It is observed that bradykinin contains a Ser-Pro-Phe motif near the site of hydrolysis. The selenium analogues of captopril represent a novel class of ACE inhib...
Background and objectives:Alzheimer’s disease (AD) is a neurodegenerative disorder. Nowadays, many investigations are performed to find new drugs for AD and medicinal plants are considered as one of the most important sources for developing new drugs. According to the role of oxidant agents and acetylcholinesterase enzyme (AChE) in AD, plants with antioxidant and AChE inhibitio...
Background & Aim: Diabetes mellitus increases oxidative stress and results in the weakening of the antioxidant defense system. Leaves of mangrove (Avicennia marina) which have not been studied enough are rich in antioxidant compounds. This study was conducted to determine the effect of aqueous extract of mangrove leaves (Avicennia marina) on the antioxidant enzyme activities of ovarian tissue i...
background: collagen, the most abundant protein in the human body, and as an extracellular matrix protein, has an important role in the fiber formation. this feature of the collagen renders establishment of the structural skeleton in tissues. regarding specific features associated with the collagen, such as, formation of the porous structure, permeability and hydrophilicity, it can also be use...
six strain of trichoderma (t. viride, t. harzianum, t. reesei, t. longibrachiatum, t. koningii, t. virens) were isolated and used for extracellular enzyme production. species of trichoderma are collected from the surrounding soil of suger beet root fields in east iran, and held in vitro cultured pda. tcm and tfm are used for the growth of spores and induceing the production of cellulase. finall...
