Novel mucoadhesive buccal tablets (NMBTs) of oxytocin were prepared as cores in cup fashion to release and permeate the drug unidirectionally toward the buccal mucosa to reach the systemic circulation directly. Adhesive cups for NMBTs were prepared with mucilage (DPM) isolated from edible Diospyros peregrina fruit. Mucoadhesive properties like shear and tensile and peel strengths of the adhesiv...
The Aim of this study is to determine the histological structure in wall layers large intestine guinea pig. cecum and colon was characterized by a delicate lining that moisturized mucus also gel by-product bacterial fermentation. This performed on ascending descending five health animals. composed four tunicae (mucosa, submucosa, muscularis serosa, tunica mucosa consist epithelium, lamina propr...
A polymer gel (ferrogel) is an assembly of ferromagnetic nanoparticles embeded in gel. In the ferrogel, the finely distributed magnetic particles are suspended in the swelling liquid and forma flexible matrix due to adhesive forces. The present paper describes an electric and acoustic study of magnetic field sensitive poly (dimethyl siloxane) ferrogel. The results showed hysteresis of acoustic ...
We have compared four methods of topical anaesthesia of the nostril for fibreoptic airway endoscopy in a randomized study with 31 unpremedicated volunteers, each serving as his or her own control. Lignocaine spray, EMLA cream, three cotton swabs soaked in 4% lignocaine solution, or 2% lignocaine gel was applied in a nostril for 3 min. Application of lignocaine spray was rated as the most unplea...
Tenofovir gel is being evaluated for vaginal and rectal pre-exposure prophylaxis against HIV transmission. Because this is a new prevention strategy, we broadly assessed its effects on the mucosa. In MTN-007, a phase-1, randomized, double-blinded rectal microbicide trial, we used systems genomics/proteomics to determine the effect of tenofovir 1% gel, nonoxynol-9 2% gel, placebo gel or no treat...
Introduction: Medications used to treat oral ulcers include corticosteroids, anesthetics, and antihistamines. These can be as gels, mouthwashes, pastes, ointments, etc. Diphenhydramine hydrochloride (DPH) has local anesthetic properties that help the aphthae. One of drawbacks delivery transmucosal is quick turnaround time gel, a mucous form located on epithelial film surface. Methods: Therefore...
AIMS To evaluate the changes in mucus gel layer thickness and prostaglandin E2 (PGE2) content caused by Helicobacter pylori infection in the antral mucosa of children: to assess whether decreased mucus gel thickness is related to PGE2 production. METHODS Antral biopsy specimens were taken at endoscopy from 153 children. H pylori gastritis was evident in 45 and normal mucosa in 59. The other 4...
Models for the pathogenesis of colorectal cancer tend to focus on the localized lesion, with less attention paid to changes in normal-appearing mucosa. Here we used two-dimensional gel electrophoresis and mass spectrometry to define patterns of protein expression in morphologically normal colonic mucosa from 13 healthy subjects, 9 patients with adenomatous polyps, and 9 with cancer. Tumor sampl...
PURPOSE Chlorhexidine is a good prophylactic agent for post-extraction dry socket alveolitis. The bio-adhesive 0.2% chlorhexidine gel could improve this action since its intra-alveolar positioning would allow a more direct action on the alveolus and more prolonged action of the medication. MATERIALS AND METHOD We present a single blind, randomised study on 30 patients to evaluate the efficacy...
