BACKGROUND Besides its haematopoietic effect, erythropoietin (EPO) has multiple protective effects, i.e. antiapoptotic, antioxidant and angiogenic properties. The neuroprotective effects of EPO against ischaemia have all been demonstrated in cell culture and animal models. The aim of the study was to evaluate the effect of erythropoietin on(More)
BACKGROUND Multiple protective effects of erythropoietin (EPO), such as antiapoptotic, antioxidant, angiogenic and neuroprotective effects, against ischemia have been demonstrated in cell culture and animal models. Genistein is also a potent tyrosine kinase inhibitor. The aims of the present study were to evaluate the effects of EPO on renal(More)
BACKGROUND Laparoscopic donor nephrectomy (LDN) is associated with prolonged warm ischemia, which could potentially increase oxidative stress in the graft. Because pneumoperitoneum (Pp) used to facilitate LDN impairs renal perfusion, it could augment the effects of warm ischemia. Our experimental, randomized, controlled study with blind outcome assessment(More)
BACKGROUND The aim of this study was to analyze the effects of 45min of hepatic ischemia and 1h of reperfusion on renal oxidative stress parameters, on renal tissue damage, and the role of Desferrioxamin (Dfx) and Q on these parameters. METHODS Thirty Wistar albino rats were randomized to five groups. Group I was the control group. Group II received no(More)
BACKGROUND This study was designed to investigate the effects of inhaled anesthetic agents on respiratory mechanics with low flow anesthesia in laparoscopic abdominal surgery. Two inhaled anesthetics, desflurane and sevoflurane, have a lower solubility in blood and tissues than all previous volatile anesthetics, and have become the preferred volatile(More)
BACKGROUND Proliferating trichilemmal tumors are rare cutaneous neoplasms that show features of typical pilar cysts but also show extensive epithelial proliferation, variable cytologic atypia, and mitotic activity. Proliferating trichilemmal tumors are benign lesions; however, there are numerous reports of malignant proliferating trichilemmal tumors. (More)
Squamous cell carcinoma (SCC) is a rare type of breast malignancy and little is known about long-term outcome. In the present report, the clinical features, histopathologic findings and postoperative course of a patient with squamous cell carcinoma are described. We have treated a 47-years-old woman who admitted for right breast mass without any discharge,(More)
BACKGROUND Pneumoperitoneum (Pp) induces ischaemia in intra-abdominal tissues. We investigated the effects of ischaemic preconditioning (IP) and low-pressure Pp methods used to reduce ischaemic injury during Pp on oxidative stress and inflammatory cytokine response. METHODS Thirty-two rats were divided into four groups. Rats in the control group were(More)
BACKGROUND Laparoscopy induces an ischemia/reperfusion (I/R) injury that elicits the production of inflammatory cytokines. The aim of this study was to test whether laparoscopic preconditioning (LP) could change hepatic inflammatory response. MATERIALS AND METHODS Twenty-four male Spraque Dawley rats were assigned into one of three experimental groups:(More)
