[ 1 ] - Reduction of hemorrhagic shock–induced acute kidney injury by lower limb ischemic preconditioning in rats
Introduction: During hemorrhagic shock (HS), the kidneys are one of the primary target organs involved. Oxidative stress is shown to be enhanced in different models of acute kidney injury (AKI). Remote ischemic preconditioning (RPC) by brief limb ischemia is considered to be a safe method to protect different organs from further damage. In this study, we investigated the effects of brief hind l...
[ 2 ] - Effect of Losartan injection into paraventricular nucleus on the deleterious effects of angiotensin II in renal ischemia-reperfusion injury
Introduction: The aim of this study was to investigate the effect of angiotensin II (Ang II) and losartan injections into paraventricular nucleus (PVN) on renal ischemia-reperfusion injury. Methods: After right nephrectomy in male rats, a cannula was inserted into the right PVN. One week later, renal ischemia-reperfusion (IR) injury was induced by clamping the left renal artery for 45 min, a...
[ 3 ] - Protective effects of celecoxib on inflammatory cytokine levels and testis indices after induction of varicocele
Introduction: Varicocele is a pathological dilation of spermatic cord vein plexus, and celecoxib, an inhibitor of cyclo-oxygenase-2, is widely used in the treatment of chronic inflammation. So, we examined the effects of celecoxib on inflammatory cytokines, testicular Sertoli and spermatogonial cells number, seminiferous tubule diameter, and sperm indices in immature male rats with induced vari...
[ 4 ] - Protective effects of celecoxib on ischemia reperfusion–induced acute kidney injury: comparing between male and female rats
Objective(s): There is increasing evidence for the importance of gender in different diseases; however, the role of gender in response to treatments is still unknown. Therefore, this study investigated the impact of gender on the protective effects of celecoxib in ischemia reperfusion (IR)-induced acute kidney injury.Materials and Methods: In this experimental study, rats were randomly divided ...
[ 5 ] - The Effects of L-Citrulline Pretreatment on the Isometric Tension of the Isolated Perfused Rat Aorta
Background: The achievement of an effective compound for prevention/treatment of hypertension with fewer complications has been of interest in recent years. OBJECTIVES: This study aimed to examine the effects of L-citrulline pretreatment on the tension of isolated rat aortic tissues precontracted by different vasoconstrictors. METHODS: Sixteen male Wistar rats (300-350g) were randomly divided i...
[ 6 ] - اثرات وابسته به دوز سولفیدهیدروژن بر آسیب حاد کلیوی ناشی از ایسکمی-پرفیوژن مجدد کلیه در موش صحرایی
Background: Renal ischemia reperfusion (RIR) injury is a common clinical syndrome that affects renal function and significantly increases morbidity and mortality. Hydrogen sulfide (H2S) is an endogenously gaseous mediator that exhibits many cytoprotective effects. Recently, studies have shown that H2S have opposite effects in different doses. Therefore, in the current study we investigated the ...
[ 7 ] - اثر آنژیوتانسین II در هسته پاراونتریکولار در تشدیدآسیب ایسکمی- پرفیوژن مجدد کلیه
Background: The renal sympathetic nerve activity (RSNA) is enhanced in renal failure. Paraventricular nucleus in hypothalamus is an important central site to regulate sympathetic activity. There are angiotensin II (Ang) II receptors in this nucleus. The aim of this study was to evaluate the effects of angiotensin II in hypothalamic paraventricular nucleus (PVN) on renal ischemia-reperfusion inj...
[ 8 ] - تغییرات سطح اینترلوکین-6 و اینترفرون-گاما با گذشت زمان در رت‌های نابالغ با واریکوسل
Background: Varicocele is a dilated vein of the pampiniform plexus that cause to det-rimental time-dependent effects so this study describes the effect of varicocele on the level of IL-6 and interferon gamma in serum and testis tissue, number of sertoli and spermatogonia cells, seminiferous tubules diameter and sperm activity in immature rats. Methods: Thirty six immature rats, 5-6 weeks aged ...
[ 9 ] - Administration of sodium hydrosulfide reduces remote organ injury by an anti-oxidant mechanism in a rat model of varicocele
Objective(s): Infertility in varicocele may have an adverse outcome on the future life of an infertile male. This study was designed to investigate whether varicocele affects remote organs, including the kidney, liver, and brain. We have also evaluated the protective effects of NaHS administration on the structure and function of these organs.Material...
