Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87～5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.

以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例，比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹丰富，而与早中期G-带带纹吻合。

Methods: The total polysaccharide was extracted with distilled water from mycelia of paecilomyces cicadae. The colorimetric MTT was used to analyze the proliferative activity of PBMC, U937 and K562 which were treated with PCPS of 7 concentrations respectively in vitro. ELISA was used to detect the content of hTNF-α, hIFN-γ from supernatant of culturing PBMC that was treated with PCPS for 44 h.

用水提取蝉拟青霉菌丝体总多糖，以MTT法测定不同浓度总多糖对人外周血单个核细胞及白血病细胞株U937、K562增殖的影响，ELISA法测定多糖作用44h后，外周血单个核细胞培养上清液中hTNF-α、hIFN-γ的含量。

Methods 18 rabbits were used to observe the osteogenesis of percutaneous autogenous bone marrow into cicatrix of bone defect.A 1cm bone defect model was made in each side of the radius.

选健康家兔18只，建立双侧桡骨中段骨及骨膜缺损1cm模型，两骨断端髓腔用骨蜡封闭。6周后，实验侧桡骨骨缺损区经皮注射自体红骨髓2ml；对照侧桡骨骨缺损区注射自身外周血2ml。

①At the 8 weeks of fetalage, the ciliated, small mucous granule cells and rare basal cells were all differentiated from endoderm cubic cells, which was 3 weeks earlier than Gaillard's report.

①人胚胎8周时，内胚层细胞已分化出气管上皮的纤毛细胞、小粘液颗粒细胞、基底细胞很少，该结果比过去Gaillard等的报告提前3周。

Great differences could be found within the universities regarding the internship duration. Compared with the 13-week CM internship at RMIT University in Australia and a 52-week internship at Nanjing University of TCM, China Medical University is the only university, which, beside a 48-week WM internship in the double degree program, also offers a 32-week WM clerkship in the five and seven year CM curriculum.

其中教育设计以「培养现代中医师」为目标的台湾中国医药大学分别在在中西医双学位课程及五年制和七年制的中医课程安排48周及32周的西医实习课程，在全球中医教育制度中独树一帜。

For two more weeks, Mother cluck ed, smiled and held Jacob. For two weeks she spoke to my father, her children and grandchildren in complete sentences.

在随后的两周里，母亲抱着雅各布，逗他、冲着他笑；两周来，母亲同父亲、同儿孙辈谈话，说的都是完整的句子。

Compared with normal control group, the proportion of CD4+CD25+ Tregs was markedly decreased in PB and MLN of model control group of experimental colitis. But it was significantly increased in therapeutic groups of SASP and CLYSTER No.

结果：建模后1～2周，模型组外周血和肠系膜淋巴结的CD4+CD25+ Tregs细胞数量较正常组明显下降，而使用SASP和中药灌肠Ⅰ号治疗后该细胞亚群明显高于模型组。

The average clinical fractures coalescence time was 8 weeks (6~10 weeks).

骨折临床愈合时间平均8周（6~10周）。

The Bone Volume Fraction of COB is 0.49±0.08 at 4 weeks after operation, only 0.16±0.05 at 12th week poster-operation, and the formation of new bone matches to the degradation of COBs.

术后4周COB的骨体积分数(Bone Volume Fraction，BVF)为0.49±0.08，术后12周仅为0.16±0.05，表明材料降解的速度与新骨长入的速度比较匹配。

Methods:(1) The levels of IL-2, NK activity in PBMC were measured in 30 patients with primary hepatic carcinoma by MTT colorize assay.
