在摇瓶水平上对布拉酵母(Saccharomyces boulardii)培养基及培养条件进行优化。先通过单因子法筛选最优碳源、氮源及无机盐,再利用响应面法优化发酵培养基组分及培养条件,采用Plackett-Burman法筛选影响布拉酵母生长的主要因素,用最陡... 在摇瓶水平上对布拉酵母(Saccharomyces boulardii)培养基及培养条件进行优化。先通过单因子法筛选最优碳源、氮源及无机盐,再利用响应面法优化发酵培养基组分及培养条件,采用Plackett-Burman法筛选影响布拉酵母生长的主要因素,用最陡爬坡试验及Box-Benhnken设计进一步优化选定的主要因素。得出最佳发酵培养基为:麦芽糖2%,蛋白胨2%,酵母浸提取物2.08%,培养基初始pH值为6;最佳发酵条件为:温度29.6℃,转速250 r/min,250 mL三角瓶培养基装量29 mL,接种量为5%,培养时间为24 h。优化后的布拉酵母菌体湿重达到32.2 g/L,比优化前(20.9 g/L)提高了54.1%;优化后活菌数达8.3×108CFU/mL,比优化前(5.5×108CFU/mL)提高了50.9%。 展开更多

AIM: To assess the efficacy and safety of Saccharomyces boulardii (S. boulardii) in acute watery diarrhoea and its role in reducing the frequency of episodes of diarrhoea in subsequent two months. METHODS: Children from 2 mo to 12 years of age, with acute diarrhoea were selected according to inclusion criteria and randomised in S. boulardii group (treated with ORS, nutritional support and S. boulardii, 250 mg bid) and in control group (treated with ORS and nutritional support only). Active treatment phase was 5 d and each child was followed for two months afterwards. Frequency and consistency of stools as well as safety of drug was assessed on every visit. A comparison of two groups was done in terms of number of diarrhoeal episode in subsequent two months. RESULTS: There were fifty patients in each group. Baseline characteristics such as mean age and the average frequency of stools were comparable in S. boulardii and control group at the time of inclusion in the trial. By d 3 it reduced to 2.7 and 4.2 stools per d respectively and by d 6 it reduced to 1.6 (5. boulardii Group) and 3.3 (control group). The duration of diarrhoea was 3.6 d in S. boulardii group whereas it was 4.8 d in control group (P = 0.001). In the following two months, S. boulardii group had a significantly lower frequency of 0.54 episodes as compared to 1.08 episodes in control group. The drug was well accepted and tolerated. There were no reports of the side effects during treatment period CONCLUSION: S. boulardii significantly reduces the frequency and duration of acute diarrhoea. The consistency of stool also improves. The drug is well-tolerated. 展开更多

AIM: To investigate the efficacy of a high-potency probiotic preparation on prevention of radiation-induced diarrhea in cancer patients.METHODS: This was a double-blind, placebo-controlled trial. Four hundred and ninety patients who underwent adjuvant postoperative radiation therapy after surgery for sigmoid, rectal, or cervical cancer were assigned to either the high-potency probiotic preparation VSL#3 (one sachet t.i.d.,) or placebo starting from the first day of radiation therapy. Efficacy endpoints were incidence and severity of radiation-induced diarrhea, daily number of bowel movements, and the time from the start of the study to the use of Ioperamide as rescue medication. RESULTS: More placebo patients had radiation-induced diarrhea than VSL#3 patients (124 of 239 patients, 51.8%, and 77 of 243 patients, 31.6%; P 〈 0.001) and more patients given placebo suffered grade 3 or 4 diarrhea compared with VSL#3 recipients (55.4% and 1.4%, P 〈 0.001). Daily bowel movements were 14.7 ± 6 and 5.1 ± 3 among placebo and VSL#3 recipients (P 〈 0.05), and the mean time to the use of Ioperamide was 86 ± 6 h for placebo patients and 122 ± 8 h for VSL#3 patients (P 〈 0.001). CONCLUSION: Probiotic lactic acid-producing bacteria are an easy, safe, and feasible approach to protect cancer patients against the risk of radiation-induced diarrhea. 展开更多
