‘槟榔芋’和‘香沙芋’母芋与子芋淀粉形态和理化性质的比较

以魁芋类的‘槟榔芋’和多子芋类的‘香沙芋’为材料,运用扫描电镜、X–射线衍射和快速黏度分析等技术比较研究了两个芋品种的母芋和子芋中淀粉的理化性质的差异。结果表明:‘槟榔芋’母芋淀粉的平均粒径大于子芋,‘香沙芋’相反。两种芋的母芋表观直链淀粉含量和淀粉颗粒外部有序度均高于其子芋。在加热过程中,两种芋的母芋和子芋淀粉的膨胀势在75℃后产生显著变化,在95℃时母芋淀粉的膨胀势大于子芋。和子芋淀粉相比,‘槟榔芋’母芋淀粉具有较高的峰值黏度、崩解值和回生值,而‘香沙芋’相反。两种芋的母芋淀粉的最终水解程度均大于其子芋。以上结果表明,两个芋品种的母芋和子芋淀粉的形态、组成和理化性质方面均存在明显差异,这将为芋淀粉在食品和非食品行业中的应用提供参考依据。

Effect of Yangyu Tuji on content of type Ⅰ, Ⅲ collagen and the expression of MMPs and TIMP-1 in wound caused by streptozotocin in rats

AIM: To study the effects of Yangyu Tuji (YYTJ) on delayed healing wound of diabetic rats caused by streptozotocin (STZ). METHODS: SD male rats were randomly divided into control group (control), model group (model); and 3 different dose groups of YYTJ. 55 mg/kg STZ were given by intraperitoneal injection except for control group. After 30 days, a round skin of 1.6 cm diametre was excised on all dorsal back of rats. The healing time and healing rate were observed according to re-epithelization. The content of collagenⅠ and Ⅲ was observed by Picric acid-Sirius red staining , Matrix metalloproteinase-1, 13 (MMP-1, -13), tissue inhibitor of metalloproteinases-1 (TIMP-1) by immuno-histochemistry assay. All data were analyzed by IPP software. RESULTS: The healing time in each group treated with YYTJ was shorter than that in model group (P<0.01), and the healing rate was increased (P<0.01, P<0.05). Content of type I collagen, ratio of type Ⅰ and Ⅲ collagen of high and mid dose group were significantly higher than that in model group (P<0.01) at 3rd, 7th, 11th day. The expression of MMP-1, -13 of each groups were higher than that in model group at 7th day (P<0.01, P<0.05), and MMP-1 trend to equal with model group at 11th day. MMP-13 was significantly lower than that in model group at 11th day (P<0.01, P<0.05). TIMP-1 of each group of wound was higher than that in model group at 3rd, 7th, 11th day (P<0.01, P<0.05). The ratio of type Ⅰ and Ⅲ collagens in each group was lower than that in model group at 11th day (P<0.01). Ratio of MMP-13 and TIMP-1 of high dose group and mid dose group were higher than that in model group at 3rd and 7th day (P<0.01). The ratio of each group was lower than that in model group at 11th day (P<0.01). Meanwhile, ratio of MMP-13 and TIMP-1 of high dose group and mid dose group were lower than that of lower dose group (P<0.05). CONCLUSION: It is possible that YYTJ accelerates wound healing by increasing collagen content of type Ⅰ and Ⅲ, especially type Ⅰ, as well as improves collagen deposition by regulating the balance of MMP and TIMP.
