Background: The fruit of Terminalia chebula (Combretaceae) has been used as traditional medicine against various human ailments, and has been extensively used in Ayurved, Uanai and Homeopathic medicine. The fruit was one of the Ayurvedic herbs used for the adaptogenic/anti-stress potential. The objective of the study was to investigate anti-stress activity of ethanolic extract of T. chebula fru...

introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...

Hypocretin/orexin acts pharmacologically in the hypothalamus to stimulate stress hormone secretion at least in part by an action in the hypothalamic paraventricular nucleus, where the peptide's receptors have been localized. In addition, orexin acts in the brain to increase sympathetic tone and, therefore, mean arterial pressure and heart rate. We provide evidence for the role of endogenously p...

The present study investigated the effect of intraperitoneal (i.p.) administration of endotoxin lipopolysaccharide (LPS) and immobilization stress on the genetic expression of corticotropin-releasing factor receptor (CRF-R) in the brains of conscious male Sprague-Dawley rats. One group of rats was killed at 1, 3, 6, 9, and 12 hr after a single intraperitoneal injection of either the LPS (250 mi...

Objective: Ethyl pyruvate (EP) is a molecule with antioxidant, anti-inflammatory, and anti-apoptotic features. The present study investigates EP's effects on behavioral biochemical alterations induced by immobilization (IM) stress. 
 Methods: In this outcome, 45 male BALB/c mice were separated into five groups [CONT (control), IM, IM+EP, EP, IM+F (fluoxetine)]. IM applied had 6 hours of st...

Panax ginseng C.A. MEYER (Araliaceae), which contains ginsenosides as its main components, has been shown to have various biological effects, including anti-inflammatory, anxiolytic, anti-stress, and anti-tumor effects. Orally administered ginsenoside Rb1 and Re are metabolized to 20(S)-protopanaxadiol (PPD) and compound K via ginsenoside Rd and 20(S)-protopanaxatriol (PPT) and ginsenoside Rh1 ...
