The results of:' analysis of edema fluid and excised lungs show that there is leakage of protein-rich fluid into the lung tissue and ultimately into the respiratory passages. This leakage cannot be explained by the reduction in oxygen uptake as observed in lung tissue slices. The ultimate cause of pulmonary edema is not known. The survival time of anesthetized dogs suffering from thermal edema ...

A technique is described for measuring objectively and quantitatively the reaction of sensitized guinea pigs when exposed to an aerosol of specific antigen. The principle involves registration by semi-automatic means of the number of coughs produced in animals passively sensitized with known amounts of antibody. The number of coughs is shown to be linearly related to log dose of antibody within...

Present work was inspired by an interesting finding of Raithel et al. (11) about remission of steroid-dependent, chronically active ulcerative colitis (UC) in a patient, after treatment with a combination of fexofenadine, disodium cromoglycate and an amino acid-based formula. Literature reports involvement of mast cells activation and increased histamine secretion in the pathogenesis of colitis...

The triazole core is one of the most imperative and well known heterocycles which composed nitrogen atom forms natural products with medicinal claims. Triazole moiety present as a principal structural component in drug categories such antimicrobial, anti-inflammatory, analgesic, antineoplastic, antimalarial, antiviral, antihypertensive, local anaesthetic, antianxiety, anti-Parkinson′s, antidepr...

Translationally controlled tumor protein (TCTP) represents an exquisite target for cancer differentiation therapy, because it was most strikingly down-regulated in tumor reversion experiments. Since TCTP is identical with the histamine releasing factor, antihistamic drugs may inhibit TCTP. Indeed, antihistaminics, such as promethazine, thioridazine, perphemazine and chlorpromazine reveal antipr...

* Present address : Pharmacology Division , Central Drug Research Institute, Chatter Manzil Palace, Lucknow, India. Hafliger (1) synthesized a series of iminodibenzyl compounds which were found to possess antihistaminic, anticholinergic, sedative and analgesic properties. It was only after a clinical trial by Kuhn (2) that G 22355 (imipramine) "emerged as an antidepres sant". The exact mechanis...

OBJECTIVE To study the effect of nimesulide (4-nitro-2-phenoxymethane sulfonanilide) a non-steroidal anti-inflammatory drug, on antihistaminic activity of cetirizine. METHOD A randomized, double blind, cross over study was conducted in ten healthy male volunteers. Wheal and flare responses to histamine were measured by performing intradermal injection of histamine (2 micrograms base) diluted ...

amitriptyline, a tricyclic antidepressant agent is used as one of the analgesic drugs in different kinds of pain. in the present study the effect of local (subcutaneous) injection of amitriptyline (50 and 100 µg) on the acute and chronic pain using formalin test, was investigated. our data show that local injection of amitriptyline to the paw receiving formalin, causes a decrease in pain in bot...
