Abstract:Protective effect of 313-hydioxy-2,3-dihydrowithanolide F against CCI4-induced hepatotoxicity has been assessed and the compound was found to possess marked protective effect. A comparison of the protective properties showed that it is more active than hydrocortisone on a weight basis.
“…The results of our study showed that WC extract administration before ischemia was able to reduce the pycnotic nucleus and widened the perinuclear space in the parietal brain cortex, which is in agreement with the findings of Budhiraja et al that showed cytoprotective effects of WC extract against CCL4-induced hepatotoxicity in rats (28). Another study showed that pretreatment with withania at a dose of 1000 mg/kg significantly improved the neurological deficit in rats (12).…”
Background: Cerebral ischemia and reperfusion (I/R) is a pathological condition that arises by reduction or cessation in cerebral blood flow and return of oxygen and metabolites to brain cells, which cause oxidative damage. Objectives: The aim of this study was to investigate the neuroprotective effects of Withania coagulans (WC) extract on brain cortex in a rat model of I/R. Materials and Methods: Thirty-two adult male Wistar rats weighing 280 -300 g were used in this study. Animals were randomly divided to four groups (n = 8) as follow: sham operated group (I), I/R group (II), WCE500 + I/R (III) and WCE1000 + I/R groups (IV). Pretreatment with WC extract (500, 1000 mg/kg) was done by oral gavage for 30 days and global brain ischemia was induced by the common carotid occlusion for 30 minutes. After 72 hours, the animals were perfused transcardially and then the brains were prepared for histological study (H & E and TUNEL staining). Results: The I/R group showed a significant increase in pycnotic (dying) neurons and pretreatment with WC at doses of 500 mg/kg and 1000 mg/kg significantly reduced pycnotic and TUNEL positive neurons, in a dose dependent manner in ischemic brain cortex. Conclusions: Our findings indicated that WC has neuroprotective effects and is able to reduce histopathological alterations and apoptosis in brain cortex I/R in rats.

“…Hyperglycemia results in the generation of free radicals who can exhaust antioxidant defenses, leading to the disruption of cellular functions, oxidative damage to membranes and enhanced susceptibility to lipid peroxidation. [2,3] Flavonoids are one of the most numerous and widespread groups of phenolics in higher plants. [4][5][6][7][8] Some of them, due to their phenolic structure, are known to be involved in the healing process of free radical-mediated diseases, including diabetes.…”
“…The hot aqueous extract of W. coagulans fruits has been shown to exert hepatoprotective, antiinflammatory and antidiabetic effects (5,6). The same hot aqueous extract of W. coagulans fruits has also increased the glucose utilization in isolated rat hemidiaphragm cells (7).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
