Gastric antisecretory and antiulcer effects of ajowan “Carum copticum†in rats
An aqueous suspension of ajowan “Carum copticum” was evaluated for its possible gastric antisecretory and antiulcer activities in various ulcer models in Wistar albino rats. The suspension at 250 and 500 mg kg/body weight, orally (i.p. in Shay rat model) has significant effect in pyloric ligation induced basal gastric acid secretion, indomethacin and noxious chemicals (80% ethanol, 0.2 M NaOH and 25%...

Formulation and evaluation of solid dispersions of Rofecoxib for improvement of dissolution profile
Rofecoxib is a non-steroidal anti-inflammatory drug, mainly used for osteoarthritis, rheumatoid arthritis, and dysmenorrhea. The major problem with this drug is its very low solubility in biological fluids, which results in poor bioavailability after oral administration. Therefore, solid dispersions of Rofecoxib with urea, polyethylene glycol (PEG) 6000 and polyvinyl pyrrolidone (PVP)...

Eupatilin: A flavonoid compound isolated from the artemisia plant, induces apoptosis and G2/M phase cell cycle arrest in human melanoma A375 cells
Eupatilin is a flavonoid compound isolated from the Artemisia plant. Eupitillin possesses antioxidant as well as potent anticancer properties. In this study, for the first time, we examined the anti-proliferative effects of Eupatilin in human melanoma A375 cells and its ability to induce apoptosis and cell cycle arrest. Eupatilin specifically induced morphological changes in A375 cells and was less toxic to...

Rifabutin loaded floating gellan gum beads: In vitro and in vivo evaluation
Rifabutin loaded floating gellan gum beads were prepared by ionotropic gelation in acidic medium. Buoyancy to the beads was attributed to the use of gas-generating agent, which produced an extremely porous internal structure lighter than gastric juice. Beads exhibited excellent buoyancy and remained buoyant up to 18 h. Drug incorporation efficiency of the beads was found to be dependent on the concentration of...

Synthesis and antifungal activity of new 1-(2,4-dichloro phenyl)-3-aryl-2-(1H-1,2,4-triazol-1-yl) prop-2-en-1-one derivatives
A series of novel 1-(2,4-dichlorophenyl)-3-aryl-2-(1H-1,2,4-triazol-1-yl) prop-2- en-1-one derivatives were synthesized in good yields by an aldol condensation between 1-(2,4-dichlorophenyl)-2-(1H-1,2, 4-triazol-1-yl) ethanone and an aryl aldehyde. The structures were established through 1H NMR and 13C NMR spectroscopy and elemental analysis. All compounds 4a-l at a concentration of 50 mg/L showed inhibition...

High phenolics and antioxidants of some tropical vegetables related to antibacterial and anticancer activities
Phytochemicals play an important role in the decrease risk of free radicals associated diseases. In the present study, total phenolic contents, antioxidant, antibacterial and anticancer activities of thirty Thai vegetables have been evaluated. The results showed that phenolic contents of Thai vegetables were highly correlated with total antioxidant activities. Four vegetables in strains of Spondias pinnata...

Immune stimulating activity of water-soluble polysaccharide fractions from Dendrobium nobile Lindl.
Four water-soluble polysaccharides (DNP1-1, DNP2-1, DNP3-1 and DNP4-2) were obtained from the aqueous extracts of the stems of Dendrobium nobile Lindl. by hot water extraction, ethanol precipitation, and fractionated by DEAE-cellulose ion exchange chromatography and Sephadex G-200 gel filtration chromatography. The evaluation of tumor inhibition and immunomodulatory activity suggested that DNP4-2 could...

Effects of the aqueous fruit extract of Solanum macrocarpum Linn on the hematological parameters of triton-induced hyperlipidemic rats
The dried and pulverized unripe fruit of Salanum macrocarpum (Solanaceae) was soxlet-extracted with distilled water. Studies were then undertaken on the effect of the aqueous extract on haematological parameters and the leukocytic response on triton-induced hyperlipidemic rats. Graded doses (25, 50, 100 and 200 mg/kg weight, bw) of the extract were...

Evaluation of the antimicrobial activity of Acalypha monostachya Cav. (Euphorbiales: Euphorbiaceae)
Acalypha monostachya (Euphorbiaceae) is used by the inhabitants of San Rafael and Zapotitlan Salinas, Puebla, Mexico, to alleviate illnesses of bacterial and fungal origin. We analyzed the antimicrobial activity of A. monostachya and some of its chemical features. The extracts were obtained by percolation. The antibacterial and antifungal activities were examined through the disc-diffusion method. The...

Ghrelin promote partial the early recovery of rats after subtotal gastrectomy
The aim of this study was to investigate the validity of exogenous ghrelin for early recovery in partial gastrectomied rats and its long-term significance. The subtotal gastrectomy (B-ltype) rats were randomly divided into two groups, and then they were treated with intraperitoneal injection of saline or ghrelin intervention respectively. Body weight and daily food intake were measured before and after the operation....
