Objectives: Investigation with the crude ethanolic extract of Argyria captiformis leaves was carried out to evaluate its possible thrombolysis and to analyze in –vivo neuro-pharmacological effects as anxiety is a particular form of behavioral inhibition that occurs in response to novel environment events and also phytochemical screening of plant extract. Method: Ethanolic extract of Argyria cap...

UNLABELLED We tested the antiplatelet effect described for propofol in vitro in surgical patients. Platelet aggregation induced by adenosine diphosphate, collagen, and arachidonic acid was tested in samples of whole blood, platelet-rich plasma (PRP), PRP with red blood cells, and PRP with leukocytes. Also measured were platelet production of thromboxane (Tx)B(2) and leukocyte production of 6-ke...

Drug shortages continue to be at the forefront of health care concerns.1,2Thiopental, an agent used for anesthesia during electroconvulsive therapy (ECT), became unavailable in North America in August 2010. The sole producer of this drug, Hospira (headquartered in Lake Forest, Illinois), ceased production because of liability concerns if thiopental were used via lethal injection to enforce the ...

While glucose-stimulated insulin secretion depends on Ca(2+) influx through voltage-gated Ca(2+) channels in the cell membrane of the pancreatic β-cell, there is also ample evidence for an important role of intracellular Ca(2+) stores in insulin secretion, particularly in relation to drug stimuli. We report here that thiopental, a common anesthetic agent, triggers insulin secretion from the int...

Mechanical ventilation is essential in intensive care units. However, it may itself induce lung injury. Current studies are based on rodents, using exceptionally large tidal volumes for very short periods, often after a "priming" pulmonary insult. Our study deepens a clinically relevant large animal model, closely resembling human physiology and the ventilator setting used in clinic settings. O...

We describe a six-compartment kinetic and dynamic physiological model of induction of anaesthesia with thiopental. The model included an accurate account of initial drug distribution by representing the inter-relationships between initial vascular mixing, lung kinetics and cardiac output, and the use of the brain as the target organ for anaesthesia (two-compartment sub-model with slight membran...

STUDY OBJECTIVE To evaluate and compare the efficacy of various pretreatment agents to attenuate or prevent opioid-induced muscle rigidity using a well-established, previously described clinical protocol. DESIGN Prospective, controlled, single-blind, partially randomized study. SETTING Large medical center. PATIENTS ASA physical status I-III patients undergoing elective surgical procedure...

Polymorphonuclear eosinophilic leucocytes (PME) participate in wound healing processes, the inflammatory response, bronchial asthma, allergies and defence against invading parasites. We have examined the effects of thiopental, methohexital, propofol, etomidate and ketamine on PME chemotaxis in vitro. PME were isolated from venous blood samples of 10 healthy volunteers using multi-stage Percoll ...

Chemicals that could be used scientifically to force an individual to tell the truth - dubbed truth sera - were first described in the early 1920s. Ever since, the notion of "truth drugs" has remained tenaciously within popular culture. One of the most important reasons for the survival of the notion of a pharmaceutical technology of authenticity was the role of the barbiturates sodium amytal a...
