OBJECTIVE To investigate the effects of lidocaine on the morphology of saphenous veins (SVs) harvested during coronary artery bypass graft (CABG) surgery. METHODS This experimental study was conducted at the Cardiovascular Surgery Department, Gazi University, Ankara, Turkey, between May and September 2007. The SVs from 11 patients who underwent CABG surgery were divided into 3 segments. Each ...

Thyroid hormones from the thyroid gland are necessary for the normal development of body organs. It was demonstrated that NO participates in the regulation of thyroid function. NO brings about oxidation reactions which will produce free radicals, and can start chain reactions that damage cells. This leads to the production of ROS. These oxidants can damage cells by starting chemical chain react...

sulfur mustard (sm) has been identified as an important chemical weapon. during the iran-iraq war of 1980-88, the extensive usage of sm against iranian civilians and military forces was proven. this agent has been shown to cause severe damage mainly in the skin, eyes, lungs,  and  respiratory  tract  in  iranian  veterans.  the  most  common  disease  is bronchiolitis obliterans (bo)). sm incre...

a hydroponics study was carried out in order to understand the behavior of antioxidant enzymes, soluble protein content and its effect on cell death in different old leaves of durum wheat. two month after planting, the different old leaves were sampled and the activity of super oxide dismutase (sod), catalase, ascorbat peroxidase and guaiacol peroxidase were measured. furthermore, the rate of c...

background & aim:  ulcer index is one of the most common diseases among people. current therapies include acid secretion inhibitors which have various side effects. herbal medicines are considered as adjuvant therapy for this disease. hydroalcoholic extract of thymus daenensis has various components such as flavonoids which contribute to gastroprotection. experimental: 35 sprague dawley rat...

Wistar rats were given a diet with 8% sodium chloride to induce hypertension and subsequently sacrificed. Glycine max powder was used reduce atenolol’s side effects during the trial. Thirty divided into five groups tested over eight weeks. Rats’ blood pressure (BP) measured tail-cuff NIBP monitor. Biochemical markers like TG, TC, HDL, LDL, VLDL, alanine transferase, aspartate lipid peroxide (LP...

a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...

Background: The current study aims to measure the effect of oxidative stress on pregnancy rates Bulgarian Murrah buffaloes during breeding and non-breeding season.
 Methods: group consisted 24 mature more than 40 days after parturition. following parameters were measured: Reactive Oxygen Species (ROS) products, Ascorbate radicals, Malondialdehyde (MDA), Nitric Oxide (NO), Super Dismutase (...

Mediator release from rat peritoneal and human lung mast cells as well as human leukemic basophils was examined to determine whether super-oxide (O(-) (2)) was concomitantly generated. Immunologic or nonimmunologic stimulation of each preparation induced parallel release of histamine and O(-) (2) within 2 min. O(-) (2) production was quantitated by superoxide dismutase (SOD)-inhibitable chemilu...
