background: nepeta dschuparensis bornm (np) is used as a medicinal herb in iran. in traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. np has antioxidant and anti-inflammatory properties. this project examined the effects of the np extract on cyclooxygenase-2 (cox-2) and interleukin-1β (il-1β) protein levels and its efficacy in neuroprot...

Objective(s) The brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. The hippocampus is highly vulnerable to ischemic insults, particularly the CA1 pyramidal cell layer. There is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. Previous studies reported that pentoxifylline (PTX) has a neuroprot...

background: stroke is the third leading cause of death. hypothermia has been recognized as an effective method in reducing brain injury. in this study, we assessed the effects of granulocyte colony-stimulating factor (g-csf) as a neuroprotective agent and mild hypothermia on mortality, behavioral function, infarct volume, and brain edema in wistar rats. methods: forty male rats were used in fiv...

Objective(s): Morphine dependence (MD) potently protects heart against ischemia reperfusion (IR) injury through specific signaling mechanisms, which are different from the pathways involved in acute morphine treatment or classical preconditioning. Since opioid receptor density changes post cerebral ischemia strongly correlated with brain histological damage, in the present study, we tried to el...

ischemia-reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. ischemia-reperfusion brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. twenty–four male wistar rats (250-300 g body wt) were used in this study. the animals were divided into four groups of 6 rat...

Introduction: There are several different molecular pathways in tissue damage by Ischemic Brain Injury. The use of antioxidants and free radical scavengers are a matter of attention by some researchers. Crocus sativus (saffron) is used previously for protective effects in ischemia state by some researchers. To assess pathologic aspects of neuroprotection of saffron in some susceptible brain are...

Background and Objectives: In the early stages of brain ischemia, the production of free radicals increases. Salvia officinalis is a rich source of antioxidant compounds. Therefore, in this study the effects of hydroalcoholic extract of Salvia officinalis on blood -brain barrier permeability and neurological deficits have been studied. Materials and Methods: In this experimental study 35 m...
