The results of physical and chemic characteristic show that the molecular weight of R-PE is 194kD, which is differ from the other reported R-phycoerythrins (240kD). The molecular weight of subunits were determined . The molecular weight of a and P subunits are alike for about 20kD. The molecular weight of y subunit is about 31 kD.The subunit composition of R-PE in Corallina officinalis is presumably 4 y , which is differ from 6 y that is reported by other researcher. Moreover, we must to do more other work to prove if it contains the fourth subunit.

对R-PE部分理化特性的研究结果表明，R-PE的分子量为194kD，与目前报道的多数R-藻红蛋白240kD的分子量不同；其α、β亚基分子量均为20kD左右，γ亚基分子量约为31kD，理论推测的R-PE亚基组成为_4γ，与前人报道的_6γ不同，而且其是否存在第四亚基还有待进一步证明；同时在变性条件下对R-PE的各亚基进行了分离纯化并对其各亚基可见光光谱特性作了研究。

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.

本研究之目的在评估与工研院生医中心合作发展出可吸收性去乙醯几丁聚醣/胶原蛋白复合之组织导引再生膜片，并选择与可吸收性之BioMend Extend 及Peri-Aid 胶原蛋白膜片，和GORE-TEX OSSEOQUEST 合成高分子膜片，及不可吸收之GORE-TEX e-PTFE合成高分子膜片，等其他四种市售商品材料共同对照评估，应用8只年龄为12个月的雄性小猎犬，均分4组(分别为7天、14天、28天、3个月)，为动物活体评估模式，在实验犬之左、右下颚第一、二小臼齿及大臼齿的颊侧区制造骨缺损后，分别植入组织导引再生膜片，依实验设定时间将小猎犬牺牲，取下缺损区骨头，以光学显微镜观察量测其牙垩质再生高度与齿槽骨再生高度之变化，以探讨其组织再生模式及评估新膜片在临床应用之适用性。

They were tied head to tail, four of them, and they heaved along to where a lane branched off from the highroad, planting their great hoofs floutingly in the fine black mud, swinging their great rounded haunches sumptuously, and trotting a few sudden steps as they were led into the lane, round the corner.
