METHODS: Fresh bovine tendo calcaneus collagen was dispersed in 0.5 mol/L acetic acid, co-precipitated with chitosan and lyophilized. Dry membranes were cross-linked in 0.05% glutaraldehyde for 24 hours. In vitro its degrading rate was measured by use of collagenase degrading test. The chitosan-collagen membrane was implanted to subcutaneous dorsal sites of SD rats. After implantation, histocompatibility, vascularity and degradation were observed in vivo.

AVI may be protein matrix and it possesses neither a membrane boundary nor an internal structure,its formation is the result of the anthocyanins transported into the vacuole bind with a protein matrix. In vacuole, AVI is irregular and jelly-like in shape. In AVIs, the attachment of anthocyanins to the matrix protein is likely to be via H-bonds to a sterically restricted site. AVI is suggested to act as vacuolar anthocyanin "trap", preferentially for anthocyanidin 3, 5-diglycosides or acylted anthocyanins. The emergence of AVI can enhance color intensity and results in the "blueness" of color in the vacuole.

花色苷液泡包涵体可能具备蛋白质基质，既无膜包裹又无内部结构，其形成是转运进液泡的花色苷与蛋白质基质结合的结果；液泡里的花色苷液泡包涵体形状不规则，象果冻；在花色苷液泡包涵体中，花色苷可能通过氢键连接于蛋白质基质的一个有限空间位点；花色苷液泡包涵体被认为是液泡中花色苷的&陷阱&，优先摄取花色素3，5-二糖苷或酰化的花色苷；花色苷液泡包涵体的存在可增加液泡色彩的强度并导致&蓝化&。
