Observation of the Inhibitory Effects on Gastric Secretion and Motility by Atropine-Like Agents
… prominent of the older therapeutic agents is atropine. | Using atropine as a standard, this paper will concern itself with an attempt to evaluate the action of newer preparations on both gastric secretion and motility in innervated and denervated pyloric pouch with gastric fistula dogs. | …

Intubation Time Required for Tracheal Intubation with Low Dose Rocuronium in Children with and without Atropine
… this time was reduced by administration of atropine. METHODS: Forty-six children, aged 3-10 years, were randomly assigned to receive either saline (control group) or atropine 10 μg/kg (atropine group). Anesthesia was induced with alfentanil 10 μg/kg, propofol 2.5 mg/kg, and rocuronium 0.3 …

The Effect of Atropine on the Bispectral Index Response to Endotracheal Intubation during Propofol and Remifentanil Anesthesia
Atropine has been reported to increase the propofol requirements for the induction of anesthesia during continuous infusion of propofol. Activation of the peripheral nerve system by endotracheal intubation is accompanied by an increase in bispectral index (BIS). The purpose of this study was to …

The Effects of Atropine Sulfate on Flight Simulator Performance and on Respiratory-Heart Period Interactions (Human, Electrocardiogram, Organophosphorous)
Atropine sulfate is an important therapeutic agent for treating anticholinesterase toxicosis, but atropine also is a strong anticholinergic drug with side effects. Twenty volunteers received a placebo control and atropine doses of 0.5, 1.0, 2.0, and 4.0 mg/75 kg in a Latin Square double blind …

Effects of blockade of muscarinic receptors in the ventral tegmental area : attenuation of cocaine reward, but enhancement of locomotor activity and dopamine overflow in the nucleus accumbens
… injections of the muscarinic receptor antagonist atropine into the ventral tegmental area attenuated the rewarding effects of intravenous cocaine self-administered on either fixed ratio or progressive ratio schedules of reinforcement. Low doses of atropine sulphate, the lipophilic form of the …

Effects of Training on Atrial Rate and Sensitivity of Isolated Rat Atria to Catecholamines and Acetylcholine
… change was higher in trained rats. 1x10-5M atropine added to isolated rat atria of trained rats increased the atrial rate to a rate almost identical to the basal atrial rate of control rats. A biphasic response of atrial rate was observed when equimolar concentrations of acetylcholine and …

Peripheral and Central Muscarinic Cholinergic Receptors in Arterial Blood Pressure Regulation
… muscarinic cholinergic (MC) blockade with atropine (central and peripheral receptor blockade) or glycopyrrolate (peripheral receptor blockade) to simulate vagal dysfunction. During the onset of LBNP -40 too, orthostatic hypotension (OH) was observed in both the older subjects and the …

Evaluation of the diving reflex in response to water-based foam vs. carbon dioxide gas depopulation in White Pekin ducks
… the treatments foam, CO2 gas and foam with an atropine injection for ducks aged 8-14 weeks. Atropine sulfate was injected to prevent bradycardia by blocking acetylcholine at parasympathetic neuroeffector sites. Experiment 1 resulted in significantly faster times to all four physiological points …

Untersuchungen zur schnellen Freigabe von HI-6 Dichlorid und HI-6 Dimethansulfonat aus verschiedenen Autoinjektorsystemen. Neue Aspekte des Stabilitätsverhaltens dieser Salze und ihrer ungepufferten, konzentrierten Lösungen.
… bispyridinium salt concomitantly given with 2 mg atropine is sufficient for first aid. Because of its instability in water, combinations of dry HI-6 powder with atropinesulfate solutions are available in autoinjectors. Since the salt is to be dissolved within seconds i.e. by shaking, the …

A COMPARATIVE STUDY OF NEWER TECHNIQUES WITH THE OFFICIAL METHOD OF ASSAY OF SOLANACEOUS ALKALOIDS
… at present appearing in most official compendia. Atropine, hyoscyamine and scopolamine* are all determined together by a single titration in this method, and the results are expressed as "total alkaloids, calculated as hyoscyaminen". The process is termed a "proximate assay", that is, one in which …
