Gastroprotective effect of Cymbopogon citratus infusion on acute ethanol-induced gastric lesions in rats.

Ethnopharmacological Relevance: Treatment of gastric ulcers with medicinal plants is quite common in traditional medicine worldwide. Cymbopogon citratus (DC) Stapf. leaves infusion has been used in folk medicine of many tropical and subtropical regions to treat gastric disturbances.

Growth and phenotypic expression of human endothelial cells cultured on a glass-reinforced hydroxyapatite.

Glass-reinforced hydroxyapatite composites (GR-HA) are bone regenerative materials that are characterized by their increased mechanical properties, when compared to synthetic hydroxyapatite. Bonelike is a GR-HA that is a result of the addition of a CaO-P(2)O(5) based glass to a HA matrix. This biomaterial has been successfully applied in clinical bone regenerative applications.

Therapeutic vaccine against Streptococcus sobrinus-induced caries.

Streptococcus sobrinus produces a virulence-associated immunomodulatory protein (VIP) which suppresses the host-specific immune response and induces the early production of IL-10. In this study, we evaluated the effects of therapeutic immunization with this VIP on the incidence of caries in S. sobrinus-infected rats.

Chemoprevention of DMBA-Induced Mammary Tumors in Rats by a Combined Regimen of Alpha-Tocopherol, Selenium, and Ascorbic Acid.

This experimental study was designed to evaluate the efficacy of associated naturally occuring antioxidants in the prevention of chemically induced breast cancer using DMBA in virgin female Wistar rats. Rats were randomly allocated to three groups: control group (CG; n = 20), induction group (IG; n = 100), and prevention group (PG; n = 70). A single dose (65 mg/kg) of DMBA was administered in the IG and PG animals at 50 days of age.
