Effect of diet with soybean on histology and histomorphometry of small intestine villi and serum level of Calcium, Phosphorus and Glucose in mice

Soybean as a cheap protein and without side effects has been introduced to food industry. This study carried out to determine the effect of diet containing soybean on histology and histomorphometry of duodenal villi and serum levels of Calcium, Phosphorus and Glucose in mice.
In this experimental study, 30 female immature BALB/c mice with 3 weeks of age were randomly allocated into control, and experimental 1 and 2. The control group was fed a diet with complete protein. Animals in the experimental 1 and 2 were received a diet of complete protein with 40% soybean and 20% soybean, respectively. After 3 months the mice were anesthetized and blood samples were taken from the heart for determining serum level of Calcium, Phosphorus and glucose. Duodenum specimens from were prepared and stained with hematoxylin and eosin.
Tissue structure of duodenum in experimental groups in compare to control group was not significantly changed, except for some scant specimens who showed some degrees of destruction in villi apicese. In histomorphometrical evaluation, the thickness of sub - mucosa and musculature were significantly increased in experimental groups compared to the controls group (P Long term consumption of soybean can induce significant alteration in serum Calcium and glucose level, thickness of sub mucosa and musculature, the height of villi and depth of crypt in duodenum.
