Effect of Qianjinjiu on the Contraction of Gastrocnemius muscle of Isolated Sciatic Nerve

Jianqing Zhu, Zhanying Qi, Chaohui Lin


Objective: To investigate the water extract from Radix (Flemingia philippinensis Merr et Rolfe Decoction.) Effect


of sciatic nerve gastrocnemius muscle Characteristics of isolated frog. Methods: The dissected lesion of sciatic nerve gastrocnemius muscle was infused with 0.9% saline, 0.125g / mL, 0.25g / mL, 0.5g / mL jelly extract, and the RM6240 bio-signal collector was used to measure each The infiltration depth of 5 minutes, infiltration for 10 minutes, infiltration of 15 minutes at each time point of the gastrocnemius muscle contraction threshold strength (measured at each time point 5 times) and complete single contraction curve (measured at each time point 25) Systolic rate, systolic rate, rate of contraction, and latency. Results: The systolic threshold intensity of the gastrocnemius muscle increased with the increase of the concentration of the extraction fluid, but less than the pre-treatment level (P <0.01, P <0.05). If the concentration and time (P <0.05). At the same time, the systolic amplitude, systolic rate and diastolic rate increased first and then decreased with the increase of the concentration of the extract (P <0.01, P <0.05). The latency of the sciatic nerve of the sciatic nerve was affected by the concentration of the drug in the infiltration solution, which decreased first and then increased with the increase of the drug concentration. Conclusion: The systolic characteristics of skeletal muscle are affected by the weight of the components. Low concentration of salt water extract in a short time to improve the ability of skeletal muscle contraction, treatment time is too long or too high concentration of crude drugs will make the skeletal muscle contractility weakened, and even inhibit the skeletal muscle contractility, and affect the nerve Muscle excitement signal transmission.
