N-acetylcysteine L-lysinate Nacystelyn (L-NAC) is a newly synthesized mucolytic agent, of which the action in vivo has not been well defined. In six healthy mongrel dogs, the rheological properties of mucus, its mucociliary and cough clearability, and the transepithelial potential difference (PD) of the tracheobronchial epithelium were evaluated after placebo and L-NAC metered dose inhaler (MDI...

Several skin conditions have been reported to occur on epidermal nevi, but it seems that co-occurrence of a vascular lesion and an epidermal nevus is a very rare phenomenon. Herein, a 17- year- old female patient who had presented with skin lesions on her thigh since 4 years ago has been reported. The lesions were two oval plaques consisted of multiple brown- tinted, hyperkereratotic papu...

epidermal nevus syndrome is a rare congenital disorder, characterized by epidermal nevi and multiple organ involvement. multicystic kidney disease has been very rarely reported in this syndrome. here is the report of a boy presented with multiple epidermal nevi, cardiac anomaly, seizure attack, hemi hypertrophy, and multicystic dysplastic kidney complicated with wilms' tumor. according to this ...

The effects of carbachol, cholecystokinin octapeptide (CCK-8), secretin, prostaglandin E2 (PGE2), and second mediator-like substances (A23187, phorbol 12-myristate 13-acetate, and dibutyryl cAMP) on mucus secretion from cultured gastric epithelial cells were investigated. Gastric mucus was measured by an enzyme-linked lectin assay with soybean agglutinin and wheat germ agglutinin. Intracellular...

BACKGROUND It has been proposed that a pathogenic effect of Helicobacter pylori is a weakening of the protective mucus barrier; however, this remains controversial. AIMS To clarify the effects of H pylori infection on the mucus gel barrier in vivo. METHODS Mucus gel polymeric structure and the thickness of the adherent mucus barrier were measured in endoscopic biopsy samples in subjects wit...

Secretion of bicarbonate into the adherent layer of mucus gel creates a pH gradient with a near-neutral pH at the epithelial surfaces in stomach and duodenum, providing the first line of mucosal protection against luminal acid. The continuous adherent mucus layer is also a barrier to luminal pepsin, thereby protecting the underlying mucosa from proteolytic digestion. In this article we review t...

adverse effects of antiepileptic drugs including cutaneous reactions may not only affect the result of treatment and quality of life, but can also be fatal if severe. skin rash is more likely to occur during the first few months of treatment. the objective of this study was description of skin rashes in users of four antiepileptic drugs. we identified skin rashes of phenytoin, carbamazepine, so...
