Pharmacodynamic study on Tianma Lingzhi Granules / 中草药

ABSTRACT

Objective: To study the pharmacodynamics of Tianma Lingzhi Granules (TLG). Methods: Mouth breathing experiment and hypoxia tolerance experiment under atmospheric pressure with mice, experiment of dizziness of guinea pigs caused by chloroform, and stimulus ischemic vertigo of model rats caused by rotating in water maze experiment was used to investigate the anti-vertigo effect of TLG; The experiment of autonomic activities of mice and hypnosis experiment of mice with pentobarbital sodium was used to investigate the sedative hypnotic effect of TLG; The experiments of torsion body and hot plate of mice was used to investigate the analgesic effect of TLG; The experiments of swimming and regulating immune experiment was used to investigate the anti-fatigue and immune regulation effect of TLG. Results: TLG could promote the supplying of oxygen in the brain, significantly reduce the times of autonomic activities of mice, increase the number of sleeping mice at the subthreshold dose of sodium pentobarbital, shorten the sleep latency of mice with hreshold dose of sodium pentobarbital and prolong the sleep time, significantly increase mice body torsion reaction latency by the acetic acid and reduce the body torsion times, and increase the spleen thymus index, clearance coefficient and phagocytic index of mice. Conclusion: TLG has the effect of treating dizziness, forgetfulness, waist and knee fatigue weakness and so on.
