十全大补汤对荷膀胱癌小鼠大剂量化疗的减毒增效作用

Objective To investigate the toxicity attenuation and efficacy potentiation effects of Shiquan Dabu Tang (SDT) on high dose chemotherapy in T739 mice with bladder carcinoma. Methods Mouse bladder carcinoma tissue was inoculated subcutaneously into T739 mice to establish tumor-beating mice model. The tumor-bearing mice were randomly divided into a CTX group (100, 200, 400 mg/Kg respectively), a SDT group (high or low dose respectively), a high-dose SDT combined with 200 mg/Kg CTX group and a control group. The body weight, diameter of tumor nodules and complete blood count were observed subsequently. Results Different doses of SDT could effectively inhibit tumor growth in mice. SDT + CTX treatment significantly prolonged the survival time of mice by 49.4±23.3 days (P<0.01, 0.05, 0.01), compared with high dose SDT treatment (17.4±5.77) days, 200 mg/kg CTX treatment (23±14.02) days and control group (11.75±2.06) days respectively. The peripheral platelet count increased more significantly in mice treated with SDT within a week as compared to mice without SDT treatment (P<0.05). The peripheral RBC count and liB concentration increased more significantly in mice treated with SDT for 2 weeks as compared to mice without SDT treatment (P<0.05). Conclusions SDT could enhance the anti-tumor effects of high dose CTX on tumor-bearing mice and reduce toxicity in its peripheral red blood cells. The results showed that SDT combined with high dose of CTX chemotherapy had toxicity attenuation and efficacy potentiation effects in tumor-beating T739 mice.

Effects of essential oil from Croton tiglium L. on intestinal transit in mice

AIM OF THE STUDY: Croton tiglium (Croton tiglium L., Euphorbiaceae) is widely used as a herb for treatment of gastrointestinal disturbances. Previous studies established its purgative and inflammational properties. The present study aimed to investigate the effects of Croton tiglium oil (CO) on intestinal transit in mice. MATERIALS AND METHODS: Gastrointestinal transit in mice and contractile characteristics of isolated intestinal strips from mice were evaluated. Intestinal inflammation was confirmed by histological examination. RESULTS: Low dose of CO increased the gastrointestinal transit of charcoal and barium meal as well as the production of fecal pellets in mice. In contrast, high dose exerted inhibitory effects. For normal colonic circular strips, both high and low dose of CO inhibited the contractile frequency. Low doses (0-20 microg/ml) of CO enhanced the phasic contractions, while high doses (>40 microg/ml) reduced them. Colonic longitudinal strips in CO-treated mice were less sensitive to electrical field stimulation than those in control mice. The contraction of colonic longitudinal, colonic and jejunal circular strips in CO-treated mice was more sensitive to atropine than that in control mice. CONCLUSIONS: CO might modulate gastrointestinal motility and induce intestinal inflammation related to immunological milieu and motor activity. Our findings may highlight the ethno-medical uses of Croton tiglium on intestinal disorders.
