Objective To study the action of Shuganwan(SHGW) on experimental gastric ulcer in mice. Methods The anti-ga stric ulcer action of SHGW was observed on the gastric ulcer induced by water im mersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secr etion in rats was studied by pyloric ligation. The effect on gastrointestinal mo tility was observed by gastric emptying in mice. The analgesic effect was tested by the hot-plate test and writhing method. Results SHGW m arkedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGW significantly inhibited the secretion of gastric a cid and pepsin and promoted the secretion of gastric mucus. SHGW markedly delaye d gastric emptying in normal mice and when gastric emptying was stimulated by ne ostigmine. SHGW mildly strengthend the effect of atropine on gastric emptying. S HGW enhanced hot pain threshold and decreased the number of twisting body in mic e. Conclusion Shuganwan may have anti-gastric ulcer ac tion. The mechanism of the action might be associated with its inhibition of the secretion of gastric juice, promotion of the secretion of gastric mucus,inhibit ion of activity of gastric smooth muscle and analgetic effect.

OBJECTIVE:To provide some references for rational application of intravenous infusion drugs to ensure the safety of drug use. METHODS:Statistical analysis was made to irrational prescriptions intercepted by the pharmacy intravenous admixture service of our hospital from 2009 to 2013. RESULTS:There were 5,802 groups of irrational prescriptions from 2009 to 2013,accounting for 0.12% of total prescriptions. For the irrationality,the top three reasons were improper solvent dosage, drug overdose and improper solvent selection in order,and the involved types of drugs were mainly antimicrobial agents,anti-neoplastic drugs,common drugs and parenteral nutrition drugs (arranged from more to less). Under the pharmacist’s interven-tion,the percentage of irrational prescriptions of intravenous drugs reduced from 0.169 4% in 2009 to 0.082 8% in 2013. The decrease in the irrational prescriptions involving with improper administration was the most significant,followed by those related to drug overdose,frequency,prescribing errors errors improper solvent dosage,incompatibility and improper solvent. CONCLU-SIONS:Pharmacists’intervention can effectively reduce the irrational prescriptions and significantly promote rational use of in-travenous drugs.

AIM: To study the action of Shugan Pills (SHGP) (Fructus Toosendan, Rhizoma corydalis, Radix Paloniae Albe, Radix Aucklandiae, Cortex Magnoliae Officinalis, Fructus Aurantii, etc.) on treatment of epigastralgia. METHODS: The analgesic effect was tested by the hot plate test and writhing method. The anti gastric ulcer action of SHGP was observed on the gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secretion in rats was studied with pylorus ligation. The effect on gastrointestinal motility was observed by determination of gastric emptying and small intestinal propulsion ability in mouse. RESULTS: SHGP enhanced hot pain threhshold and decreased the number of twisting body in mouse. SHGP markedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGP significantly inhibited the secretion of gastric acid and pepsin and promoted the secretion of gastric mucus. SHGP markedly delayed gastric emptying in normal mouse and when gastric emptying and small intestinal propulsion was stimulated by neostigmine. SHGP faintly strengthed the effect of atropine on inhibition of gastrointestinal motility. CONCLUSION: Shugan Pills could have analgesic effect, anti gastric ulcer action, it inhibited the secrection of gastric juice and the activity of gastric smooth muscle. These effects might be the pharmacological mechanisms of SHGP on treatment of epigastralgia.
