Printed in Great Britain. STRESS INTXJCED FACILITATION OF OPIATE CATALEPSY IN THE RAT
نویسندگان
چکیده
1. Adult male Sprague-Dawley rats were injected with a standard low dose of opiate (10 mg/kg of morphine sulfate). 2. Experimental subjects received one of two stressful procedures (tail pinch, floor cooling) while control subjects were not disturbed. 3. Using motor activity as an index of catalepsy, both stressful procedures prolonged the syndrome. 4. Stress may therefore affect this opiate mediated process.

Objective(s): Neuroinflammation and oxidative stress play a key role in pathogenesis of Parkinson’s disease (PD). In the present study we investigated the effect of reactive oxygen species (ROS) scavenger WR-1065 on catalepsy and cerebrospinal fluid (CSF) level of interleukin 6(IL-6) and striatum superoxide dismutase (SOD) activity in 6-hydroxydopamine (6-OHDA) induced experimental model of PD...

We have shown that buspirone, a partial agonist of 5-hydroxytryptamine 1A (5-HT1A) receptors, improves motor dysfunctions induced by 6-hydroxydopamine (6-OHDA) and haloperidol in rats. The present work extends these findings by investigating the role of 5-HT1A receptors on catalepsy-like immobilization in rats, a model of Parkinson’s disease. Catalepsy was induced by unilateral infusion of 6-OH...

Objective(s): Neuroinflammation in Parkinson disease (PD) is associated with glial cells activation and production of different inflammatory cytokines. In this study, we investigated the effect of chronic administration of 8-OH-DPAT on 6-OHDA-induced catalepsy and levels of inflammatory cytokines in cerebrospinal fluid (CSF). Materials and Methods: Catalepsy was induced by un...

Murraya koenigii L. (Rutaceae), commonly known as curry leaf tree, closely associated with south India where the word “curry” originates from the Tamil “kari” for spiced sauces. Curry leaves are a rich source of carbazole alkaloids which possess various biological activities such as antitumor, antioxidant and anti-inflammatory. Curry leaf has a potential role in the treatment of diabetes....
