Actions of Ba and Sr Ions on Isolated Rat Ileum

Inhibitory actions of eugenol on rat isolated ileum.

The effects of eugenol (1-2000 microM) on rat isolated ileum were studied. Eugenol relaxed the basal tonus (IC50 83 microM) and the ileum precontracted with 60 mM KCl (IC50 162 microM), an action unaltered by 0.5 microM tetrodotoxin, 0.2 mM N(G)-nitro-L-arginine methyl ester, 0.5 mM hexamethonium, and 1 microM indomethacin. Eugenol did not alter the resting transmembrane potential (Em) of the l...

Two-photon transitions in Ca, Sr, and Ba ions

Two-photon 2E1 decay rates are calculated for the metastable 3dj states in Ca , 4dj states in Sr , and 5dj states in Ba + to evaluate contributions of these transitions to the corresponding lifetimes. The calculations are carried out using the relativistic single-double method, where single and double excitations of Dirac-Fock wave functions are included to all orders of perturbation theory. We...

The Transport of Salt and Water across Isolated Rat Ileum

The flows of sodium, potassium, and chloride under electrical and chemical gradients and of salt and water in the presence of osmotic pressure gradients are described by phenomenological equations based on the thermodynamics of irreversible processes. The aim was to give the simplest possible description, that is to postulate the least number of active transport processes and the least number o...

ANTISPASMODIC EFFECT OF AERIAL PART OF TEUCRIUM POLIUM L. ESSENTIAL OIL ON RAT ISOLATED ILEUM IN VITRO

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...
