Mast cell stabilizing and anti-anaphylactic activity of aqueous extract of green tea (Camellia sinensis)

Anti-Trypanosoma cruzi activity of green tea (Camellia sinensis) catechins.

The trypanocidal action of green tea catechins against two different developmental stages of Trypanosoma cruzi is reported for the first time. This activity was assayed with the nonproliferative bloodstream trypomastigote and with the intracellular replicative amastigote parasite forms. An ethyl acetate fraction from Camellia sinensis green tea leaves, which contains most of the polyphenolic co...

Anti-Acanthamoeba effect of Camellia sinensis extract (black and green tea) in vitro

Background: Acanthamoeba is a resistant protozoan that causes severe diseases, such as GAE and CAK. Because many medications are ineffective on the parasite, the quest to find alternative drugs is in progress. Objective: This research was aim 13 ed to assess the performance of the black and green tea extracts on Acanthamoeba. Methods: The clinical isolate of Aca...

An aqueous extract of green tea Camellia sinensis increases expression of Th1 cell-specific anti-asthmatic markers.

The present study provides evidence of the anti-asthmatic signaling activity of an aqueous fraction of green tea using specific in vitro and in vivo assays in an ovalbumin-induced asthmatic model. Mice sensitized to ovalbumin were orally administered an aqueous extract of Camellia sinensis. The lungs of these mice were then examined by hematoxylin and eosin staining and ELISA analysis to measur...

Inhibitory Activity of Green Tea (Camellia sinensis) Extract on Some Clinically Isolated Cariogenic and Periodontopathic Bacteria

OBJECTIVE To determine the in vitro inhibitory activity of green tea extract on some clinically isolated cariogenic and periodontopathic bacteria. MATERIALS AND METHODS Twenty strains of each of Streptococcusmutans, Aggregatibacteractinomycetemcomitans, Porphyromonasgingivalis, and Prevotellaintermedia were isolated from carious teeth and periodontal pockets of patients with dental caries and...
