Flos Lonicerae is one of the oldest and most commonly prescribed herbs in Eastern traditional medicine to treat various inflammatory diseases. In the present study, we investigated the effects of ethyl acetate fraction of Flos Lonicerae (GC-7101) on experimental gastric ulcer models and its mechanisms of action in gastric ulcer healing. The pharmacological activity of GC-7101 was investigated i...

A randomised, double-blind, placebo-controlled parallel study was conducted in adult females to evaluate the efficacy andsafety of a combination of cimetidine 300 mg orally and metoclopramide 10 or 20 mg intravenously in reducing pre-operative residual gastric volume and raising gastric pH. The effect of preoperative metoclopramide on postoperative nausea and vomiting was also investigated. Ora...

Nonsteroidal anti-inflammatory drugs often cause development of significant GI lesions. Selective inhibitors of prostaglandin G/H synthase/cyclooxygenase-2 (PGHS-2) enzyme and some dual inhibitors of PGHS/5-lipoxygenase (5-LO) enzymes have been reported to be potent anti-inflammatory compounds that carry a much lower risk of having GI irritating effects. We have evaluated the anti-inflammatory ...

Meloxicam is a non steroidal anti-inflammatory drug, used in the treatment of rheumatoid arthritis and oestoarthritis. It is practically insoluble in water leading to poor dissolution, variations in bioavailability and gastric irritation on oral administration. In order to modulate its gastric side effect and to increase aqueous solubility, physical mixture and solid dispersion of the drug were...

objective(s) ziziphora clinopodioides lam. is a plant widely used in iranian traditional medicine for gastrointestinal disorders. several reports have demonstrated antibacterial (helicobacteria pylori), antioxidant and anti­inflammatory properties of z. clinopodioides. the aim of this study was to investigate the effects of aqueous- ethanol extract of z. clinopodioides on rat’s gastric acid out...

Gastrointestinal (GI) diseases affect a large number of people all over the world. Uncontrolled acid secretion and occurrence of gastric ulcers are common disorders of GI tract which pose serious problems to human health. Many synthetic drugs have been used to treat GI disorders but a definite cure has not been discovered so far and the available medications cause several side effects. Nigella ...

The article describes a two-step synthesis of diastereomeric 3-hydroxy-2-methyl-3-(4-biphenylyl)butanoic acids. In the first step an intermediate alpha-bromo propanoic acid 1-ethoxyethyl ester was synthesized. The second step is a new modified Reformatsky reaction in presence of Zn in tetrahydrofuran (THF) at -5 to 10 degrees C between the previously synthesized intermediate and 4-acetylbipheny...

The integrity of gastric barrier derives from the balance between defending and damaging factors. In particular, prostaglandins play a relevant role in the maintenance of gastric homeostasis and prevention of peptic disease, at different levels. Omega-3 fatty acids, particularly eicosapentanoic acid, are the precursors of the third series of prostaglandins (with anti-inflammatory properties), a...

The leaves of three Ligularia species belonging to the family Compositae, Ligularia stenocephala, L. fischeri, and L. fischeri var. spiciformis, were qualitatively and quantitatively analyzed on the caffeoylquinic acids by HPLC and subjected to peroxynitrite-scavenging assay. The IC(50) of the MeOH extract of L. stenocephala was 1.62+/-0.03 mug/ml and the major caffeoylquinic acids of L. stenoc...
