the effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 hz, 40v, 0.5 msec for 5 m). this inhibition was largely, though never completely, reversed by naloxone. contractions...

o objective: many biological studies have been done to determine the activity of medicinal plants on gastrointestinal function. since acetylcholine is the major transmitter involved in the gastrointestinal motility and there are some evidences regarding the cholinergic modulatory effect of hops extract, in the present study spasmolytic and antispasmodic action of hops(humulus lupulus) on acetyl...

dementia is one of the age related mental problems and a characteristic symptom of various neurodegenerative disorders including alzheimer’s disease. desmodium gangeticum dc. (leguminosae) is widely used in ayurveda for treating various neurological disorders. in the present study, the effectiveness of aqueous extract of d. gangeticum in attenuating scopolamine-induced amnesia in mice was inves...

Some molecules in nature have a positive or negative charge. One such molecule is acetylcholine. Acetylcholine positively charged that responsible for Alzheimer's disease. This study evaluated acetylcholine through six simple based on the ionization potential and HOMO-LUMO gap obtained from density functional theory calculation. The calculation results showed could explain stability of other mo...

effects of venom from black scorpion androctonus crasicuda (ac) were determined on isolated chick biventer cervices nerve-muscle and mouse hemidiaphragm preparations using twitch tension method. the isolated nerves were stimulated by electrical stimulator and response to each stimulus was recorded. the venom mainly acted prejunctionally to facilitate neuromuscular activity due to an increase in...

Muscarinic acetylcholine receptors (mAChRs) (nomenclature as agreed by the NC-IUPHAR Subcommittee on Acetylcholine Receptors [53]) are activated endogenous agonist acetylcholine. All five (M1-M5) mAChRs ubiquitously expressed in human body and therefore attractive targets for many disorders. Functionally, M1, M3, M5 preferentially couple to Gq/11 proteins, whilst M2 M4 predominantly Gi/o protei...

Teucrium polium L. (Lamiaceae) is used in the traditional medicine of Iran for the treatment of disorders of the gastrointestinal tract. The essential oil from the aerial parts of T polium was assessed for antispasmodic activity and compared with the effect of atropine and dicyclomine. Acetylcholine and KC I were used for induction of contraction on rat isolated ileum. Teucrium polium essen...

Aim: To assess the effect of Omeprazole at neuromuscular junction with and without Pancuronium. Study design: Experimental randomized control study. Place duration study: Department Pharmacology, Islamic International Medical College, Rawalpindi from October 2018 to September 2019 Methods: In this experimental study both a student’s oscillograph cumulative dosage response curve were used record...

a blocker of postsynaptic acetylcholine receptors was isolated from venom of the eastern green mamba dendroaspis angusticeps, by gel filtration, ion-exchange and reverse phase high performance liquid chromatography. the isolated component blocks neuromuscular transmission and responses to exogenously applied acetylcholine in isolated chick biventer cervices preparations. these results suggest t...
