Objective To observe the influences of Dingguier umbilical paste,oral Dingguier and combined medication on spleen-stomach deficiency-cold in j uvenile rats.Methods A total of 1 3 6 SD rats were randomly divided into 1 1 groups:normal control group,model control group, model vehicle group,small-dose Dingguier umbilical paste group,medium-dose Dingguier umbili-cal paste group,large-dose Dingguier umbilical paste group,Xiangshaliuj un pill+small-dose Ding-guier umbilical paste group,Xiangshaliuj un pill+medium-dose Dingguier umbilical paste group, Xiangshaliuj un pill+large-dose Dingguier umbilical paste group,Xiangshaliuj un pill group,and o-ral Dingguier group,with 1 2 or 1 3 rats in each group.Spleen-stomach deficiency-cold was induced by vinegar feeding.Body weight,food intake,gastric acid secretion,gastric acidity,pepsin activity,gastric emptying rate and small intestinal propulsion rate were measured in all the 1 1 groups.In addition,plasma levels of cholecystokinin octapeptide (CCK-8 )and motilin (MTL)were deter-mined by ELISA.Results Compared with normal control group,body weight,small intestinal propulsion rate and MTL levels were decreased but gastric acid and pepsin secretion was not changed in model control group,suggesting that rats with spleen-stomach deficiency-cold had gas-trointestinal motility disorders.Compared with model control group,body weight was improved in medium-dose Dingguier umbilical paste group,and plasma CCK-8 levels were decreased in Xiang-shaliujun pill+medium-dose Dingguier umbilical paste group 14 days after model establishment (P<0.01).However,compared with model control group,body weight in other groups and gas-tric emptying rate and small intestinal propulsion rate in rats treated with Dingguier were not changed significantly (P>0.05).Compared with normal control group,plasma MTL levels de-creased in model control group and model vehicle group,but increased in small-dose Dingguier umbilical paste group (P<0.05).Conclusion Dingguier umbilical paste and combined medication can regulate the secretion of gastrointestinal hormones and improve the symptoms of spleen-stom-ach deficiency-cold in j uvenile rats.

Objective To observe the antidiarrheal and analgesic effects of Dingguier paste on the mouse. Methods Tho diarrhea mouse models were made by senna leaf or castor oil to detect the antidiarrheal effect of Dingguier paste combination with other drugs. The hot plate test and acetic acid test were used to observe the analgesic effect of Dingguier oral medicine and Dingguier paste in combined use with other drugs. Results Compared with senna leaf model group, Dingguier paste low-dose, middle-dose, high-dose combined with diphenoxylate, Bupi-Yichang pill and Dingguier oral medicine group could decrease the number of feces in 2 h [Number of each group feces was(0.50±1.27), (2.27±2.90), (1.18±1.83);(2.00±2.26), (3.40±2.17), (3.82±1.72);(0.73±1.56), (1.91±2.95), (2.55±2.11)]. Dingguier paste low-dose and high-dose combined with diphenoxylate could decrease the number of feces in 4h [Number of each group feces was (6.70±2.11), (6.27±3.20)]. Dingguier oral group decrease the number of feces in 6h [Number of feces was (6.91±2.77)]. Compared with castor oil model group, Dingguier paste low-dose combined with diphenoxylate could obviously decrease the number of feces in 2 h, 4 h and 6 h [Number of each group feces was(0.45±0.82), (0.45±0.82), (4.27±2.15)]. Dingguier paste middle-dose combined with diphenoxylate could decrease the number of feces in 6 h [Number of feces was (4.64±2.45)]. Dingguier oral group decrease the number of feces in 2 h, 4 h, 6 h [Number of each group feces was (0.45±0.82), (2.91±2.07), (4.27±2.15)].Compared with normal group, the threshold of pain stimulated by hot plate of the Dingguier paste each dose combined with rotundin could increased remarkable after 30 min, 60 min, 90 min and 120 min[The time of Dingguier paste low-dose was(52.32 ± 17.29)s, (56.24 ± 12.48)s, (57.28 ± 6.61)s, (58.58 ± 4.70)s; the time of Dingguier paste middle-dose was (48.27±19.35)s, (54.92±12.59)s, (55.91±11.48)s, (55.15±12.49)s;the time of Dingguier paste high-dose was (49.15±15.69)s, (56.24±11.89)s, 60 s is(59.08±2.93)s]. Compared with normal group, the eclipse time of pain irritated by acetic acid of the Dingguier paste middle-dose combined with indomethacin could increased remarkable(14.72±5.99)min, the writhing frequency could decrease of the Dingguier paste each dose combined with indomethacin[Number of each dose writhing frequency was (7.62±8.31), (3.62± 6.14), (11.25±9.46)]. Conclusion Dingguier paste in the combination use with other drugs and Dingguier oral medicine may have some antidiarrheal and analgesia effects.
