Abstract

This study was undertaken in order to elucidate the effects of raw, roast and steamed buckwheat on fecal protein, Pancreas weight, the activities of $\alpha-amylase,$ chymotrypsin and lipase 91 the pancreas, and $\alpha-amylase,$ chymotrypsin and trypsin activities of the feces in streptozotocin-induced diabetic rats. Fecal proteins of raw, roast and steamed buckwheat diabetic groups were increased up to 99%, 91%, 103%, respectively compared to those of the diabetic control group. Feeding of buckwheat diet increased pancreas weight, especially raw buckwheat diabetic group(p<0.05). Pancreatic chymo-trypsin activity was decreased in buckwheat diabetic groups compared to diabetic control group, wheres any significant difference was observed in $\alpha-amylase$ and lipase activities. Fecal chymotrypsin activi-ty was significantly increased in all buckwheat diabetic groups. Fecal trypsin activity was increased in roast buckwheat diabetic groups compared to diabetic control group and fecal $\alpha-amylase$ activity in buckwheat diabetic group was not significantly different. These results suggest that feeding of buckwheat diet enhances the impaired exocrine pancreatic function of diabetic rat.

STZ 유발 당뇨쥐에 날메밀, 볶은메밀, 찐메밀을 식이의 50%가 되도록 각각 혼합한 메밀식 이를 급여하여 2주간 사육시킨 후 변의 단백질 함량, 췌장무게, 췌장의 $\alpha-amylase,$ chymotrypsin, lipase환성 및 변의 $\alpha-amylase,$ chymotrypsin, trypsin 활성을 각각 측정하였다. 변중 단백질 함량은 당뇨대조군에 비하여 당뇨날메밀군, 당뇨볶은메밀군, 당뇨찐메밀군에서 각각 99%, 91%, 103% 유의적으로 증가하였으며 , 췌장 무게는 당뇨대조군과 비교하여 당뇨날메밀군에서 24% 유의적으로 증가하였다. 췌장의 $\alpha-amylase$ 및 lipase 환성은 당뇨대조군과 당뇨메밀군들 사이에 유의적인 차이가 없었으나 chymotrypsin 활성은 당뇨찐메밀군에서 45% 유의적으로 감소하였다. 변의 $\alpha-amylase활성은$ 당뇨대조군과 당뇨메밀군들 사이에 유의적인 차이가 없었으나, chymotrypsin 활성은 모든 당뇨메밀군들에서, trypsin 활성은 당뇨볶은메밀군에서 유의적으로 증가하였다.
