Abstract: ObjectiveTo study the analgesic effects of water decoction of Armadillidium vulgare in mice.MethodsThe analgesic effects of water decoction from Armadillidium vulgare in mice were studied in mice and rats using writhing reaction, hot plate nociceptive test and tail flick test. ResultsThe analgesic experiment showed that protein of water decoction from Armadillidium vulgre at the dose of 90,180,360 mg * kg-1 had significant inhibition to writhing response (P <0.01, P <0.05) induced by acetic-acid.The inhibitory rate was
from 32.00% to 58.15% . The pain threshold in mice with the hot-plate procedure increased obviously after being taken
water decoction from Armadillidium vulgare for 30 min and 45 min (P <0.01, P <0.05). The three groups with different
doasges could obviously increase the pain threshold in imce.The pain threshold in rats procedure increased obviously after being taken water decoction from Armadillidium vulgare for 60 min and 90 min in the tail flick test (P <0.01, P <0.05). The three groups with different dosages could obviously increase the pain threshold.ConclusionThe water decoction from Armadillidium vulgare has significant analgesic effect on animal models and shows obviously dose effect

Armadillidium gynecology for the rat animal dry flat beetle Armadillidiam vulgave all , located in Guangdong, Hebei, Shandong, Jiangsu, Zhejiang and other places. Mainly contains polysaccharide, protein, formic acid, with
detoxification and pain relief, Poxue diuresis effect. China has been reported , will be late Armadillidium decoction for liver cancer pain, the role of persistent superior to pethidine, people to have for the treatment of post-operative
pain. Are reported in the literature , mouse protein from women's analgesic effect. To this end, this paper Armadillidium decoction objects protein content as an indicator, using two kinds of animal models of three analgesic analgesic effect of complex Armadillidium decoction study for the further development of women and the mouse provide experimental theoretical basis for the clinical use of drugs .

1.5 Statistical analysis of experimental data with ? s
said that the group was used to compare between the two groups t test.
1.6.1 Analgesia induced by acetic acid writhing test in mice [3,4]
Obtained 12 h fasting mice 50 (male and female half and half) were randomly divided into five groups, group 1 gavage (ig) saline, as negative control group; Group 2 gavage (ig)
tramadol hydrochloride 15 mg / kg, as a positive control group; the first 3 to 5 groups were fed different doses of decoction complex Armadillidium by the test solution group (protein content, respectively 90,180,360 mg * kg-1) 3 doses.
30 min after administration of each group, respectively, each mouse intraperitoneally (ip) 0.6% acetic acid 0.1 ml/10 g, observed within 20 min whether rat writhing produced by the emergence and writhing and calculates the number of twist body reduction in the number percentage (%). Temperature in the
entire experiment (21 ? 1) ?.
Reduction in the number writhing percentage (%) = control group, mean number of writhing - writhing test drug group mean

1.6.2 mouse hot-plate method 
Will be 50 female mice (screening, 5s <pain threshold
<30s) were randomly divided equally five groups of 10 rats. Group 1 gavage (ig) saline, as negative control group; Group 2
gavage (ig) tramadol hydrochloride 1.5 mg / kg, as a positive control group; the first 3 to 5 groups were fed different doses of rat Women decoction material by test solution (protein content, respectively 90,180,360 mg * kg-1) 3 doses.
15,30,45, and 60 min after gavage of mice was recorded to occur into hot-plate reaction time licking hind (s) as the pain threshold. If the hot plate in mice after 60 s to stay pain-free response, should be immediately removed by 60 s calculated. Pain threshold increased percentage (%) as
Increased pain threshold values (%) = after treatment the average pain threshold - before treatment the average pain
threshold before treatment the average pain threshold × 100%
1.6.3 rat tail flick method 
To (55 ? 1) ? water bath for the heat-induced pain
source. Wistar rats were obtained after fixation, be tipped into the water and more than 5 cm in the tail of rats were recorded from the surface of the water into the water to shrink the time interval of 5 min measured twice, and pick the average tail-flick reaction time 3 ~ 10 s within the 50 rats, evenly divided male and female, were randomly divided into five groups, group 1 gavage (ig) saline, as negative control group; Group 2 gavage (ig) of tramadol hydrochloride 1 mg /
ml, as a positive control group; the first 3 to 5 groups were fed different doses of decoction complex Armadillidium by the test solution group (protein content of 90,180,360 mg * kg-1)
3 doses. 30,60,90,120,150 min after the administration of rats
were measured by tail-flick time, the pain threshold increased percentage (%).
From Table 1 shows that, compared with the control group, in the acetic acid-induced writhing analgesia in mice
experiments, tramadol hydrochloride and complex Armadillidium decoction three dose groups by acetic acid-induced writhing
response in mice were significantly inhibition (P <0.01), complex Armadillidium decoction of low, medium and high doses of 3 to reduce the percentage of writhing were 32.00%, 48.15%,
58.51%. With the administration of analgesic effect of the increase in the amount of a dose-dependent manner. Table 1
complex Armadillidium decoction of the acetic acid-induced
writhing reaction in mice (abbreviated)
Hot plate in the mouse experiment, hydrochloric acid tramadol and complex Armadillidium decoction could prolong the pain threshold in mice hot-plate reaction time (P <0.05 or P
<0.01). Complex Armadillidium decoction to play in the 15 min after ig efficacy, 30 min or so for maximum efficacy. Complex Armadillidium decoction low, medium and high doses of analgesic effect with the administration of the amount of the increase in a dose-dependent manner. The results in Table 2. Table 2 complex Armadillidium decoction of mouse hot-plate
thermal stimulation experimental effects (abbreviated)
Thermal stimulation in the rat tail flick, the mouse women decoction things low, middle and high dose group can obviously improve the thermal stimulation in rat tail-flick
pain threshold, and the administration of pre-basic pain
threshold and the control group were significant difference (P <0.05 or P <0.01), and Armadillidium decoction things low, medium and high 3-dose analgesic effect with the
administration of a dose-dependent increase in the amount of
relationships shown in Table 3. Thus, complex Armadillidium decoction with the analgesic effect. Table 3 complex Armadillidium decoction on rat tail-flick test thermal
stimulus effects (? s)

diuresis effect. It has been reported Armadillidium for post-
operative pain, liver pain, the effect is comparable with pethidine. Civil useful amount of fresh Armadillidium Jianzhi oral only abdominal pain, and Armadillidium treatment of
cancer pain analgesic effect of certain clinical observations . The experimental results show that complex Armadillidium decoction of multiple pain models have a strong analgesic effect for clinical applications of the scientific basis.
