The main chemical compositions of tea flower were studied. It is the first time to determine the levels of protein, reducing saccharides and SOD activity in different blooming stages of tea flowers collected from three cultivars of Camellia sinensis with different picking time. Results showed that there were significant differences among cultivars and blooming stages, as well as the change of these chemical constituents along with time. Consequently we selected the right cultivar that has high protein, reducing saccharides or SOD activity and the fitting deflower time.

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

The results showed that with the normal dosage 60g/hm2, inhibiting rate of the plant height and weight of Taiyu 2, Jinzhenzhu, Taiyu 15, Zinuo and other three breeds are beyond 40% and 30%, and it is obvious that plant growing is inhibited, the leaves etiolate and new leaves twist severely and couldn't grow normally. Inhibiting rate of the plant height of Ziyu 2, Taiyu 2, Liaoyu 18, Ludan 50, Zhengdan 958 and some other varieties are between 30.6% and 38.1%, the sensitivity of these varieties are lower and the plant modalities are not influenced bigger; in addition, Nongda 108, Nongda 2008, Xinyu 958 and Taiyu 12 grow healthy, the resistance to nicosulfuron are higher compared with other varieties.
