INTRODUCTION Pulsatile hyperglycaemia resulting in oxidative stress may play an important role in the development of macrovascular complications. We investigated the effects of sustained vs. pulsatile hyperglycaemia in insulin resistant rats on markers of oxidative stress, enzyme expression and glucose metabolism in liver and aorta. We hypothesized that liver's ability to regulate the glucose h...

The present study has been designed to evaluate the liver protective and in-vivo antioxidant role of Ethanolic extract (EtAS) and Ethyl acetate extract (EAAS) of roots of Argyreia speciosa, an important 'rasayana' herb in Indian System of medicine, in CCl(4)-induced hepatotoxicity and oxidative stress in rats. Animals were treated with EtAS and EAAS at doses of 200 mg and 400 mg/kg body weight ...

INTRODUCTION The evaluation of pain intensity is still a subject of research. Mostly psychological evaluations are used. We started to conduct biochemical evaluation in animal experiments. Now we present biochemical evaluation in postoperative pain in man. MATERIAL AND METHODS In 67 patients herniotomy was done. For pre-emptive analgesia morphine and pethidine were used and the following indi...

There is growing evidence that oxidative stress contributes to the pathogenesis of hypertension. Our aim was to measure oxidative stress in hypertensive subjects, and assess the potential confounding influences of antihypertensive therapy. Serum malondialdehyde and antioxidant levels were estimated in patients at the time of presentation and also after a antihypertensive therapy for 3 months. D...

The present study was carried out using mice model of chronic fatigue syndrome (CFS) in which mice were forced to swim everyday for 7 days for a 6 min session. There was a significant increase in despair behavior (immobility period) in saline treated mice on successive days. Treatment with potent antioxidants carvedilol (5 mg/kg, i.p.) and melatonin (10 mg/kg, i.p.) produced a significant reduc...

BACKGROUND It is generally agreed that physiological levels of melatonin, a hormone secreted by the pineal gland, are important in protecting against oxidative stress-induced tissue damage. AIM We investigated the effects that pinealectomy and the administration of exogenous melatonin have on the brains, testes, duodena and stomachs of rats. MATERIALS AND METHODS Pinealectomized (Px) and sh...

The data presented in this article is related to the research article "RNAi of selected candidate genes interrupts growth and development of Helicoverpa armigera" (Chikate et al., 2016) [1]. RNA interference (RNAi) is emerging as a potent insect pest control strategy over current methods and their resistance by pest. In this study we tested 15 different in vitro synthesized dsRNAs for gene sile...

The petroleum ether, chloroform, methanol and aqueous extracts of the leaves of Ageratum conyzoides Linn. (Asteraceae) were evaluated for their wound healing activity in rats using excision (normal and infected), incision and dead space wound models respectively. The effects of test samples on the rate of wound healing were assessed by the rate of wound closure, period of epithelialisation, wou...

HIV infection and illicit drugs are known to induce oxidative stress and linked with severity of viral replication, disease progression, impaired cell cycle regulation and neurodegeneration. Studies have shown that morphine accelerates HIV infection and disease progression mediated by Reactive oxygen species (ROS). Oxidative stress impact redox balance and ROS production affect cell cycle regul...

OBJECTIVE Lipoic acid (LA) is an effective anti-oxidant agent that can scavenge free radicals in biological systems. The aim of this research was to study the probable protective effect of LA in spinal ischemic/reperfusion (I/R) injury. MATERIALS AND METHODS Thirty male Wistar rats, weighing 230-285 g, were assigned randomly into 3 groups (10 animals in each group): sham spinal I/R, and spina...
