Antioxidant and antiapoptotic activities of deprenyl and estradiol co-administration in aged rat kidney

Aging is a progressive degeneration process in living organisms. Deprenyl is an irreversible monoamineoxidase B inhibitor which has antioxidant, antiapoptotic and neuroprotective effects. Estradiol is also a neuroprotective and antioxidant hormone. The objective of this study was to determine whether the antioxidative effects of deprenyl can suppress apoptotic activity, with or without estradiol, in aged female rat kidney. Wistar Albino female rats were divided into six groups as follows; young (3 months old) control, aged (24 months old) control, aged deprenyl treated, aged estradiol treated, aged deprenyl plus estradiol treated and sham. All rats except for the sham group were injected for 21 days. Determination of oxidative stress parameter was performed spectrophotometrically. To detect apoptotic cells, TUNEL staining and caspase-3 immunohistochemistry were performed. Deprenyl and estradiol administration, alone or in combination, decreased significantly the levels of lipid peroxidation relative to aged control and sham-injected rats. The number of TUNEL positive cells decreased significantly in deprenyl and estradioltreated rats compared with aged control and sham rats. Deprenyl and estradiol replacement attenuated age-related changes in renal morphology. The results indicate that deprenyl treatment alone, or in combination with estradiol, may modulate age-related apoptotic changes in rat kidney by decreasing oxidative stress

Intravenous paracetamol versus dexketoprofen in acute migraine attack in the emergency department: A randomised clinical trial

Objective Migraine is a common form of headache that is a major burden for patients who often seek emergency care. The goal of this study was to compare the effectiveness of intravenous non-steroidal antiinflammatory medication (dexketoprofen) with paracetamol (acetaminophen) in the treatment of an acute migraine attack. Materials and methods This prospective, randomised, double blind, controlled study was conducted in a tertiary care emergency unit. Study patients were randomised into two groups to receive either 50 mg of dexketoprofen trometamol or 1000 mg of paracetamol intravenously by rapid infusion in 150 mL of normal saline. Pain reduction was measured at baseline, and after 15 and 30 min, using a Visual Analogue Scale (VAS)) as the primary outcome. VAS is a measurement tool ranging from 0 (no pain) to 100 mm (worst pain). Results 200 patients were included in the final analysis. Mean (SD) age of the study subjects was 30.1±11 years and 81% (n=162) were women. Median reduction in VAS score at 30 min was 56 (IQR 30-78.5) for the paracetamol group and 55 (IQR 34-75) for the dexketoprofen group, with a difference of 1 mm (95% CI -7 to 10) between the two groups. Conclusions Intravenous paracetamol and dexketoprofen appear to produce equivalent pain relief for migraine in the emergency department

Carnosine attenuates oxidative stress and apoptosis in transient cerebral ischemia in rats

Cerebral ischemia leads to cognitive decline and neuronal damage in the hippocampus. Reactive oxygen species (ROS) play an important role in the neuronal loss after cerebral ischemia and reperfusion injury. Carnosine has both antioxidant and neuroprotective effects against ROS. In the present study, the effects of carnosine on oxidative stress, apoptotic neuronal cell death and spatial memory following transient cerebral ischemia in rats were investigated. Transient ischemia was induced by occlusion of right common carotid artery of rats for 30 min and reperfusion for 24 h or 1 week. Rats received intraperitoneal injection of 250 mg/kg carnosine or saline 30 min prior to experiment. Determination of antioxidant enzyme activities was performed spectrophotometrically. To detect apoptotic cells, TUNEL staining was performed using an In Situ Cell Death Detection Kit. Carnosine treatment elicited a significant decrease in lipid peroxidation and increase in antioxidant enzyme activities in ischemic rat brains. The number of TUNEL-positive cells was decreased significantly in carnosine-treated group when compared with the ischemia-induction group. Carnosine treatment did not provide significant protection from ischemia induced deficits in spatial learning. The results show that carnosine is effective as a prophylactic treatment for brain tissue when it is administered before ischemia without affecting spatial memory
