catalpol protects dopaminergic neurons from lps-induced neurotoxicity in mesencephalic neuron-glia cultures.inflammation plays an important role in the pathogenesis of parkinson's disease (pd). microglia, the resident immune cells in the central nervous system, are pivotal in the inflammatory reaction. activated microglia can induce expression of inducible nitric-oxide synthase (inos) and release significant amounts of nitric oxide (no) and tnf-alpha, which can damage the dopaminergic neurons. catalpol, an iridoid glycoside, contained richly in the roots of rehmannia glutinosa, was found to be neuropr ...200617049947
the activities of antioxidant enzymes in response to oxidative stresses and hormones in paraquat-tolerant rehmannia glutinosa plants.all members of r. glutinosa show the unique characteristic of intrinsic tolerance to paraquat (pq). antioxidant enzymes have been proposed to be the primary mechanism of pq resistance in several plant species. therefore, the antioxidant enzyme systems of r. glutinosa were evaluated by comparatively analyzing cellular antioxidant enzyme levels, and their responses of oxidative stresses and hormones. the levels of ascorbate peroxidase (apx), glutathione reductase (gr), non-specific peroxidase (pox ...200415479627
