BACKGROUND This study evaluated the protective effect of sildenafil on liver injury induced by intestinal ischemia-reperfusion. METHODS Forty female Sprague Dawley rats were divided into 4 groups: sham-control (SC), ischemia (I), ischemia-reperfusion (IR), and ischemia-reperfusion+sildenafil (SIL; sildenafil gavaged at 50mg/kg before operating). A 2-h(More)
We evaluated the effects of L-carnitine on apoptosis of germ cells in the rat testis following irradiation. Male Wistar rats were divided into three groups. Control group received sham irradiation plus physiological saline. Radiotherapy group received scrotal gamma-irradiation of 10 Gy as a single dose plus physiological saline. Radiotherapy + L-carnitine(More)
The present study, we hypothesized that L-carnitine can minimize germ-cell depletion and morphological features of late cell damage in the rat testis following gamma (gamma)-irradiation. Wistar albino male rats were divided into three groups. Control group received physiological saline 0.2 ml intraperitoneally (i.p.), as placebo. Radiation group received(More)
The present study evaluated the effects of curcumin on epithelial cell apoptosis, the immunoreactivity of the phospho-c-Jun N-terminal kinase (JNK) and phospho-p38 mitogen-activated protein kinases (MAPKs) in inflamed colon mucosa, and oxidative stress in a rat model of ulcerative colitis induced by acetic acid. Rats were randomly divided into three groups:(More)
PURPOSE In this study, we tested the effects of L-carnitine (LC) on radiation-induced ileal mucosal damage. MATERIALS AND METHODS Thirty Wistar albino rats were divided into five groups. The control group received physiological saline intraperitoneally (i.p.). Radiation-1 and radiation-2 groups received whole-body X-irradiation of 8.3 Gy as a single dose.(More)
BACKGROUND The present study was performed to determine the effect of amifostine in the prevention of radiation-induced acute and late period morphologic damages in rat kidney via light and electron microscopic examinations. MATERIALS AND METHODS Control rats (n=6) received saline solution 30 min before sham irradiation; the radiotherapy alone group(More)
Curcumin has several biological functions particularly antioxidant and anti-inflammatory. The aims of this study are determination of the protective effects of curcumin on cisplatin-induced renal tubular cell apoptosis and related pathways in kidney. Eighteen male Wistar albino rats were randomly divided into three groups (n = 6): the control, cisplatin(More)
The aim of this study was to evaluate the role of vitamin E in follicular degeneration and to assess histopathological and biochemical changes following ischemia-reperfusion (IR) injury in rat ovaries. Twenty-eight Wistar albino rats were randomly divided into four groups: sham, 4h torsion, 24h detorsion, and a vitamin E group. Thirty minutes before(More)
We investigated the role of the Fas/Fas ligand (FasL) signaling pathway in diabetic male infertility. Male rats were divided into two groups: a control group and a streptozotocin induced diabetic group. Thirty days after induction of diabetes, samples of testes were harvested and fixed in 10% formalin for light microscopy. Germ cell apoptosis was determined(More)
We investigated the morphologic and molecular effects of exposure to cadmium (Cd) for 30 and 60 days on the uteri of mice. We assessed uterine morphometric measurements, eosinophilia, mast cell numbers, endometrial apoptosis, proliferation and estrogen receptor alpha (ERα) immunoreactivity. We examined vaginal smears that reflected the hormonal alterations(More)
