Abstract:

Background:Asthma is a major health problem worldwide. Antiasthma drugs have side effects and can be expensive. It is important to develop antiasthma drugs from medicinal plants that have fewer side effects and are cheaper. One of the medicinal plants used for antiasthma treatment comes fromCurcuma aeruginosa(Zingiberaceaefamily). The aim of the research is to examine spasmolytic activity of ethanol extract ofC. aeruginosaon isolated guinea pig tracheas to determine the antiasthma effects.Methods:The spasmolytic activity ofC. aeruginosaextracts was tested in separated organs of guinea pig trac

Abstract:

5-Hydroxytryptamine (serotonin, 5-HT) contracts the guinea pig trachea through stimulation of 5-HT2A receptors, an effect previously reported to rapidly desensitize. The present studies were designed to examine further the putative desensitization to serotonin. In vitro studies investigating functional desensitization of the guinea pig tracheal 5-HT2A receptor documented that 5-HT (3 × 10−7 M) significantly (50%) but incompletely reduced subsequent tracheal maximal contraction to 5-HT. In contrast, an equieffective concentration of carbamylcholine (3 × 10−8 M) did not reduce guinea pig trachea

Abstract:

It is speculated that bradykinin may play an important role in asthma. Thus, bradykinin receptor antagonists may have therapeutic potential against asthma. Orally active bradykinin antagonists would be more desirable for the treatment of the disease. In the present study, we examined the effects of a novel, potent, selective, and orally active nonpeptide bradykinin B2 receptor antagonist, FR167344 (N-[N-[3-[(3-bromo-2-methylimidazo[1,2-a]pyridin-8-yl)oxymethyl]- 2,4-dichlorophenyl]-N-methylaminocarbonylmethyl]-4-(dimethylaminocarbonyl)cinnamylamide hydrochloride), on guinea-pig tracheal smooth

The existence of substance P immunoreactive nerves in the trachea of guinea pig is known. In this study, capsaicin induced a long-lasting and marked contraction in the guinea pig trachea and nicotine-induced contraction was partially reduced in the capsaicin-treated muscle. Furthermore, the contractile response to nicotine (10−5 M) in the presence of atropine (10−7 M) was abolished by a substance P antagonist, [D-Arg1, D-Pro2, D-Trp7,9 Leu11]substance P (10−5 M).

Abstract:

Histamine produces constriction of tracheal smooth muscle via H1 receptors, but it also decreases tracheal smooth muscle tone via H2 and H3 receptors. In addition, it has already been reported that phenylethylamine is competitive antagonist of histamine N-methyl-transferase (HMT), enzyme responsible for rapid inactivation of histamine. Our results suggest possibility that phenylethylamine as competitive antagonist of histamine N-methyl-transferase leads to potentiation of histamine induced constriction of isolated guinea-pig trachea, which could be consequence of decreased histamine methylatio

Generation of chemiluminescence was decreased by more than 50% when the tissues were co-incubated with superoxide dismutase (100 U/ml).

Abstract:

An age-related change in potency of L-isoprenaline in the presence of ascorbic acid, desmethylimipramine, corticosterone, pargyline, and phentolamine was obtained in tracheal strips from guinea pigs of differing ages between 6 and 40 weeks. The potency in the strips from 100-week-old guinea pigs did not significantly differ from that in strips from 40-week-old animals. Single cells were prepared from the tracheal muscles of 6-, 10-, 40-, and 100-week-old guinea pigs. The specific binding of [3H]dihydroalprenolol to the single cells was saturable. The dissociation constants of [3H]dihydroalpren

Abstract:

Nebulized amiloride has been proposed as therapy in cystic fibrosis to block Na+ hyperabsorption in airway epithelium and prevent dehydration of secretions. Patients with cystic fibrosis often have reactive airways. Bovine and canine trachea relax to amiloride in vitro, suggesting another benefit as a bronchodilator, whereas guinea pig trachea, a useful model of human airways, does not. We hypothesized that human airways would respond like guinea pig airways. Airway ring segments from guinea pigs, mice, and human fetuses were constricted with the concentration of acetylcholine producing 50–75%

The purpose of the study was to evaluate the importance of the epithelium in determining the potency of exogenous vasoactive intestinal peptide (VIP) in inhibiting responses of isolated guinea pig trachea to vagal stimulation. Isolated innervated tracheal preparations (n = 56) were mounted in glass organ baths in Krebs-Henseleit (K-H) solution at 37 degrees C and gassed with 95% O2–5% CO2. The inside of the trachea was separately perfused with K-H solution at 1 ml/min. The vagal nerve trunks were stimulated (20 V, 1-ms pulses, 10-s trains) at low (0.5 Hz) and high frequency (15 Hz) alternately

Acetylcholine (ACh) release from postganglionic cholinergic nerves was elicited by electrical field stimulation (EFS) (40 V, 0.5 ms, 32 Hz). In human bronchi, pilocarpine inhibited the contractile response to EFS in a dose-rela

Using this system we evaluated how the presence of intact epithelium can affect pharmacological responsiveness. We first examined responses of tracheae with intact epithelium to histamine, acetylcholine, and hypertonic KCl when stimulated from the epithelial or serosal side. We t

In quiescent cells, stimulation with a single impulse evoked an excitatory junction potential (EJP). In 30% of these cells, trains of stimuli evo
