Abstract
The role of the intestinal flora played for hearlth is great and now it has been studied especially in relation with carcinogenesis and ageing.
In this study, the authors have examined the influence of the enteral nutrients used after the operation on the digestive tract, concerning changes in the intestinal flora (particularly Bacteroidaceae, Eubacterium, Bifidobacterium and Clostoridium).
The subjects were 20 cases of stomach cancer the ages of the patients ranged from 36 to 72 years. S-185 and B were used for enteral nutrients. Intestinal flora were analyzed by retrieving 10g of feces before and often the operation, until the restoration of normal diet. The analysis was made in accordance with Mitsuoka's method.
The number of bacteria was reduced immediately after operation in both groups due to the influence of antibiotics. In the S-185 group, Bifidobacterium and Bacteroiddaceae appeared after the nutrient was used, and they were in creasing thereafter, while in the B group, Bacteroidaceae appeared in small numbers, and it increased smoothly, but the appearance of Bifidobacterium was delayed, and no increase was noted.
When both groups were compared regarding Bifidobacterium, it was found that it showed a V-shaped recovery in the S-185 group, whereas in the B group, the recovery was delayed.
This may be attributable to the difference of carbohydrates contained in both nutrients.
The autllors also studied on the effects of the changes in the intestinal flora during the pathological states of the patients.
