摘要
Aqueous extracts of the leaves of Larrea divaricata Cav. exert antimitogenic effects on tumor cells (BW 5147 murine immature T-lymphoma) and normal, stimulated lymphocytes. The effective concentration was four times smaller in the case of tumor cells than in the case of normal, stimulated lymphocytes. Inhibitor studies of arachidonate pathway suggest that the proliferative effect of the extract is due to the activation of lipoxygenase metabolism, while the inhibitory action could be a direct effect.
