<P><B>ABSTRACT</B></P><P>Resveratrol has a neuroprotective effect against cerebral ischemia. The objective of this study was to identify proteins that are differentially expressed in the cerebral cortex of vehicle- and resveratrol-treated animals during ischemic injury. Focal cerebral ischemia was induced as middle cerebral artery occlusion (MCAO) in male rats. Rats were treated with vehicle or resveratrol before MCAO, and cerebral cortex was collected 24 hr after MCAO. Cerebral cortex proteins were identified by two-dimensional gel electrophoresis and mass spectrometry. Several proteins were identified as differentially expressed between vehicle- and resveratrol-treated animals. Among these proteins, expression of peroxiredoxin-5, isocitrate dehydrogenase [NAD<SUP>+</SUP>], apolipoprotein A-I and ubiquitin carboxy terminal hydrolase L1 was decreased in the vehicle-treated group, whereas resveratrol attenuated the injury-induced decrease in expression of these proteins. However, expression of collapsing response mediator protein 2 was increased in the vehicle-treated group, whereas resveratrol prevented the injury-induced increase in the expression of this protein. These findings suggest that resveratrol modulates the expression of various proteins that associated with oxidative stress and energy metabolism in focal cerebral ischemia.</P>

Acute (24 h) and chronic (90 days) oral toxicity studies on the ethanol extract of Trigonella foenum-graecum Leguminosae (L.) seeds were carried out. Acute dosages were 0.5, 1.0 and 3 g/kg while chronic dosage was 100 mg/kg per day of the extract. All morphological, biochemical, haematological and spermatogenic changes, in addition to mortality, body weight changes and any change in vital organs were recorded. Histopathological investigations were done on vital organs. Growth arrest in the treated animals was observed. The treated mice gained no significant weight during chronic treatment while there was a significant gain in body weight of the control group mice. Biochemical studies revealed a significant decrease in blood sugar levels of fenugreek treatment groups while haematological parameters remained comparable to the control. In the treatment,male group there was a significant decrease in weight of testes as compared to the control. There was a marginal weight gain in kidney weight of mice after chronic treatment as compared to the control. Fenugreek chronic treatment caused a highly significant spermatotoxic effects in male mice.

Purpose The present study aims to investigate the neuroprotective effects of carnosine-entrapped elastic liposomes (CARELs) against cerebral ischemia. Methods CAR-ELs were prepared by extrusion method using egg phosphatidylcholine (eggPC) as a phospholipid and Tween 80 (TW80) as an edge activator (eggPC:TW80 = 8:2, w/w). The prepared CAR-ELs were purified by centrifugal ultrafiltration followed by characterization for particle size, polydispersity index, zeta potential and entrapment efficiency. The elasticity of CAR-ELs, the most distinct feature of elastic liposomes, was determined using a stainless steel pressure filter and compared with that of conventional liposomes. In vivo neuroprotective effects of CAR-ELs were evaluated in cerebral ischemia induced by permanent middle cerebral artery occlusion (pMCAO) in rats. CAR-ELs (250 mg/kg of CAR) were intravenously administered 20 min before pMCAO and 6 h after pMCAO, respectively. The infarct volume in brain was measured by staining with 2,3,5-triphenyltetrazolium chloride after 24 h of cerebral ischemia. Results CAR-ELs showed nanometric particle size near 100 nm and homogeneous distribution with polydispersity index below 0.1. The elasticity of CAR-ELs was 2-fold higher than that of conventional liposomes. The brain ischemia was successfully developed with pMCAO as indicated by highly infarcted hemisphere (~ 50%) in saline-treated rats. The pretreatment with CAR-ELs significantly reduced infarct volume (7.9%) compared with CAR solution (19.1%)- and saline (50.8%)-pretreated rats. CAR solution, however, showed better neuroprotective effects than CAR-ELs when administered 6 h after ischemia induction. Conclusion The pre-treatment with CAR-ELs could be promising nanocarrier-based neuroprotective therapeutics against ischemic stroke.
