Background Ephedrine was conventionally regarded as the first-choice drug to maintain maternal blood pressure during spinal anesthesia for cesarean delivery, due to its stimulant activity on α- and β-adrenergic receptors. Norepinephrine is a weak β-adrenergic and potent α-adrenergic receptor agonist. Therefore, it may be suitable for maintaining blood pressure with less chronotropic effects com...

Ephedrine, an α1 and β agonist, that increases blood flow to muscles thus the cardiac output. This concept is used in this study as speed by which drug reaches neuromuscular junction partly determines onset of action muscle relaxants. Our hypothesis was ephedrine could hasten rocuronium bromide. The time shorter after administration there no difference laryngoscopic viewsand hemodynamics betwee...

BACKGROUND The ingestion of either caffeine (C) or ephedrine (E) has been shown to improve performance during high-intensity aerobic activity lasting 10-20 min, with an additive effect being found when the combination (C + E) was ingested. It was the purpose of this study to determine if the addition of E to C would improve performance in activity lasting longer than 20 min. METHODS One and o...

introduction: estimating ephedrine’s effect on animal’s locomotor activity and evaluation of cumin fruit essential oil (feo) effect and mechanism of ephedrine-induced hyper-locomotion. methods: a new protocol developed for evaluation of manic behavior induced by ephedrine in a dose and time dependent manner. following the suppressive effects of cumin feo on acquisition and expression of ephedri...

As set forth in a recent note we have shown that Chinese Ma Huang is obtained from various species of Ephedra, E. eguisetina, Bunge; E. sinica, Stapf ; and E. mahuang, Liu. So far there has been no differentiation made between the various samples of this drug which occur upon the Chinese market. However, irrespective of the possible variation in the drug samples we consider i t is essential tha...

Ephedra gerardiana (E. gerardiana,), commonly known as "Ma-huang," is a medicinal plant native to the Himalayan region. Historically, it has long traditional use in various indigenous systems for purpose. The current review aims summarize present knowledge on botanical description, phytochemistry, uses, and pharmacological properties of E. gerardiana. This study was thoroughly based previous li...

OBJECTIVES This study examined the hypothesis that the sympathomimetic activity of ephedrine increases the risk of lethal arrhythmias. BACKGROUND The sympathomimetic amine, ephedrine, is used to augment physical performance and as a weight loss aid, but little is known about the cardiovascular consequences in individuals with ischemic heart disease. METHODS Fifteen dogs at low risk for vent...

BACKGROUND Obstetric or non-obstetric surgery can be performed in pregnant women during the second trimester. We evaluated maximal sensory block level (MSBL), and other sensory block characteristics after spinal anesthesia in early and late second trimester pregnant women. METHODS Forty-four pregnant women scheduled for cervical cerclage under spinal anesthesia in the early second trimester (...

The cause of the urinary alcohol level (UAL) cycle in rats fed ethanol at a constant rate has been shown to involve the hypothalamic-pituitary thyroid axis. Because the effect of thyroid hormone on the metabolic rate is augmented by catecholamines, the role of catecholamines was investigated by using the intragastric ethanol feeding model of alcoholic liver disease in which the UAL cycles over ...
