carum carvi (cc) is a grassy plant which is believed to have several therapeutic effects, including anti-asthmatic properties. we have therefore studied the bronchodilatory and anticholinergic effects of this plant. the bronchodilatory effects of the aqueous extract (ae), macerated extract (me), essential oil (eo), and 4µm theophylline (t) in comparison with saline (s) were examined by their re...

the β2-adrenergic effects of macerated extract, aqueous extract, ethanol extract, and essential oil of carum copticum, 5 nm propranolol, and saline were tested by performing cumulative log concentration-response curves of isoprenaline-induced relaxation of precontracted isolated guinea pig tracheal chains in three different conditions including: non-incubated (group 1, n=9) incubated with 1 µm ...

in a previous study, the relaxant and anticholinergic (functional antagonism) effects of bunium persicum (b. persicum ) have been demonstrated on guinea pig tracheal chains. to elucidate the other mechanisms responsible for this relaxant effect, the inhibitory effect of this plant on histamine h1 receptors was examined in this study. the antihistaminic effects of aqueous and macerated extracts,...

WARDANI, W., JAENUDIN, APANDI, I., KUSUMAWATY, A. & SANTOSO, W. 2021. A new species of Deparia from New Guinea. Reinwardtia 20(2): 57−61. — stellata is a highland in Eastern Guinea, described specimen found among unidentified piles Guinean Expedition 1975. Its distinctive stellate-hairs on all axis and occasionally rachis-scale margin are the main character that differentiate to other Depar...

Background: Exposure to ionizing radiation is known to have various effects on hematological parameters of biological sample. This study was aimed at evaluating the effect of ionizing radiation on some hematological parameters in guinea pigs. Materials and Methods: Thirty-six (36) apparently healthy adult guinea pigs of both sexes weighing between 700g – 1200...

Sodium valproate (SV), an antiepileptic drug has several mechanism of action. It inhibits voltage sensitive Na+ channels and reduces intracellular Na accumulation. These actions are similar to that of both phenytoin and carbamazepine. We have investigated the direct cardiac action of SV and its effects on ouabain-induced arrhythmia in isolated guinea-pig atria. The guinea-pig atrium was dissect...

This paper reports comparative analyses of phase noise in Hartley, Colpitts, and common-source cross-coupled differential pair LC oscillator topologies in 28 nm CMOS technology. The impulse sensitivity function is used to carry out both qualitative and quantitative analyses of the phase noise exhibited by each circuit component in each circuit topology with oscillation frequency ranging from 1 ...

Quantum dynamics at a reactive two-state conical intersection lying outside the Franck-Condon zone is studied for a prototypical reaction of ultraviolet photodissociation of ozone in the Hartley band. The focus is on the vibrational distributions in the two electronic states at intermediate interfragment distances near the intersection. Such intermediate distributions of strongly interacting ph...
