Brief Summary:
The purpose of this study is to evaluate the effect of "combined probiotics" to improve the gastrointestinal function and intestinal bacteria flora

Condition or disease Intervention/treatment Phase
Gastrointestinal Function Intestinal Bacteria Flora Dietary Supplement: probiotics Not Applicable

Detailed Description:

Probiotics were known to improve gastrointestinal function before. This is a single-blind placebo control clinical study. We will perform gastrointestinal function questionnaire and collect stool as baseline data before the study (0-week). Then healthy subjects will be randomized to two groups.

Experimental: probiotics 1 pack bid for 3 weeks. Probiotics : (AB-kefir):Lactobacillus acidophilus,Bifidobacterium longum,Lactobacillus paracasei,Lactobacillus rhamnosus,Lactobacillus fermentum,Streptococcus thermophilus,Lactobacillus helveticus,Kluyveromyces fragilis. Other components include starch,oligosaccharide,yeast powder, superior standard spice, calcium pantothenate, VitB1, VitB12, biotin and folic acid.

Placebo group: placebo 1 pack bid for 3 weeks. Placebo: Except the probiotics (AB-kefir),the other components are the same with study group.

Then gastrointestinal function questionnaire and stool collection will be performed at the end of 1st, 2nd, 3rd, and 4th weeks after starting the study.

Estimated Study Completion Date : April 2012

Arm Intervention/treatment
Experimental: probiotics
1 pack bid use for 3 weeks
Dietary Supplement: probiotics
probiotics 1 pack (2g) bid for three weeks

Placebo Comparator: Placebo
placebo 1pack bid for 3 weeks
Dietary Supplement: probiotics
probiotics 1 pack (2g) bid for three weeks




Primary Outcome Measures :
  1. Changes of gastrointestinal function after probiotics use [ Time Frame: 28 days ]
    Changes of gastrointestinal function, such as constipation, abdominal distension and appetite after proiotics and placebo use.


Secondary Outcome Measures :
  1. Changes of intestinal bacteria flora after probiotics use [ Time Frame: 28 days ]
    1. Changes of intestinal bacteria flora: (1) aerobic bacteria count (2) anaerobic bacteria count (3) Bifidobacterium count (4) Clostridium perfringens count (5) Staphylococcus aureus count (6) E. coli and K. pneumoniae count
    2. The ratio for the antibiotics resistant bacteria ( such as Vancomycin-resistant Enterococcus,third-generation cephalosporin resistance E. coli, Methicillin-resistant Staphylococcus aureous, Extended-spectrum beta lactamase E. coli and K. pneumoniae)
    3. Changes of the bacteria virulence factors for the intestinal E. coli and K. pneumonia
