Abstract 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.

Abstract Available information on the anatomy of the respiratory system of the pampas deer ( Ozotoceros bezoarticus , Linnaeus 1758) is scarce, so the aim of this work was to describe the upper respiratory tract anatomy of this species. The study was performed with 10 adult animals of both sexes and the study method was simple dissection. Pampas deer had a nasolabial plane different to the small domestic ruminants. The nasal cavity had the fundamental conformation of the ruminants with simple winding of the dorsal concha and double winding of the ventral one. The vomeronasal organ communicated directly with the oral cavity by the incisive duct. The larynx was located ventrally to the first two cervical vertebrae. The total length of the larynx was 52.76 ± 7.66 mm from the epiglottis to the cricoid cartilage. The dorsoventral length was 30.32 ± 3.71 mm. It is necessary to make detailed histological examinations of the distribution of the olfactory epithelium versus non-sensory epithelium within the nasal cavity. These data are essential to understand the function of the turbinates and the nasal cavity in general. In the same way, detailed studies of the physiology of the vomeronasal organ and larynx are necessary.
