Experimental example 1: imperial fragrant Asthma capsule Pharmacodynamic test of active extract
1 experimental drug
1.1 claimed by the reagent name: star China institute of materia medica, imperial fragrant Asthma capsule (LXP) 980428 Shaanxi
1.2 being subjected to the reagent thing prepares: get the LXP content and add the 5%CMC-Na mixing in right amount respectively, the medicine that is made into same equivalance, variable concentrations is standby.Its leachate of isolated test.
1.3 drug efficacy study solvent: 0.5%CMC-Na
2 route of administration
Adopt the filling stomach method consistent with the clinical administration approach.Capacity is with mice 0.2ml/10g, rat 1.0ml/100g, Cavia porcellus 0.5ml/100g; Dosage is seen each test respectively under one's name.
3 experimental techniques and result
3.1 drawing, histamine-acetylcholine spraying breathes heavily test: the Cavia porcellus of getting 150~200g, put into the fog chamber, constant speed, constant sprayed into 2% acecoline and 0.1% histamine phosphate's mixed liquor 15 seconds, observation causes that animal breath is rapid, the time of tic and tumble, and with the tumble time be the qualified animal of asthma less than 120 seconds animal.The animal that asthma is qualified is divided into 8 groups at random, and 10/group, experimental group gavages LXP 0.2,0.4,0.8g/kg, once a day, and continuous 5 days, after the last administration one hour, with said method, draw the time of breathing heavily vapor recording Cavia porcellus tumble, the results are shown in Table 1.
