Acid in the esophagus causes airway constriction, tracheobronchial mucous secretion, and a decrease in tracheal mucociliary transport rate. This study was designed to investigate the neuropharmacological mechanisms controlling these responses. In chloralose-anesthetized cats (n = 72), we investigated the effects of vagotomy or atropine (100 μg·kg(-1)·30 min(-1) iv) on airway responses to esopha...

The structure and morphological change of the excretory gland in the mucous membrane of the maxillary sinus was studied and discussed on the structural principles of these pneumatic csvity found by Goto and his co-workers. 1. The excretory gland of the maxillary sinus is a tubulo-cellular gland consisted of the tubar and cavitary part, and the latter is further divided into the tubular and cell...

In the present work, stress was given for improvised local action of the drug with the addition of mucoadhesive polymer in the formulation. Oral mucoadhesive semi solid gel was prepared for the treatment of oral sub mucous fibrosis, which provides effect for extended periods of time. Curcumin was taken as a model drug as it exhibits profound antitumeric & antimutogenic activity. The semisolid p...
