OBJECTIVE: To find a effective method by which the potency of Chinese materia medica (CMM) on the central nervous system (CNS) could be correctly investigated.
METHOD: The cerebrospinal fluid(CSF) and serum after oral CMM 1 to 1.5 hours was gained and then added into the astrocyte cell culture medium. After 48 h, the above medium was in proportion transferred to the neuron culture medium. Typan blue staining, LDH and MTT test were utilized to observe the drug effect on the neuron survival.
RESULTS: The serum, but not the CSF, showed the toxicity on the astrocyte. MTT test on the neuron survival showed that the OD492nm value in the CMM group was higher than the other groups (P < 0.05). The astrocyte medium stimulated by the CSF including CMM could promote the neuron axon growth.
CONCLUSION: If observing the CMM potency on CNS in vitro, the CSF was better than the serum, we called it "Cerebrospinal Fluid Pharmacology in Chinese Materia Medica". Furthermore, the CMM could induce the neurotrophy of astrocyte.
