Toxicological and cytotoxic evaluation of standardized extracts of Galphimia glauca.

Galphimia glauca Cav (Malpighiaceae) has been widely used in Mexican traditional medicine as a remedy for the treatment of mental disorders, principally as a sedative and tranquilizer. The sedative activity of extracts obtained from this plant has been demonstrated with different neuropharmacological models. Different triterpenes, known as galphimines, have been identified from the active extract.

Comparison of the immune responses against Salmonella enterica serovar Gallinarum infection between naked neck chickens and a commercial chicken line.

The immune responses of indigenous naked neck (NaNa and Nana) and normally feathered (nana) chickens against a Salmonella Gallinarum (SG) infection were evaluated and compared with those of a commercial line (B-380). Groups of 28-day-old chickens (NaNa, Nana, nana, and B-380) were immunized orally and subcutaneously with 50 microg of SG antigens. Control non-immunized animals were inoculated with sterile saline solution.
