Methods HPDLFs were primary cultured from tissue explants, and the cells of the 5th to 8th passages were used after immunohistochemical identification of keratin and vimentin expressions. The cells were divided into 5 groups and treated with TP at 1, 0.5, 0.25, 0.125, and 0.0625 mg/ml, respectively, with another group without TP treatment as the blank control group. Cell counting and MTT colorimetric assay were performed to assess the cell proliferation, and flow cytometry was employed to determine the DNA content of the HPDLFs.

The immunosuppressive effect was determined with ratio of lymphocyte blastogenesis,phagocytotic function of macrophage,percentage of peripheral T-lymphocyte,delayed type hypersensitivity and antibody forming cell assay.

免疫抑制作用：测定小鼠脾淋巴细胞转化率；巨噬细胞的吞噬功能；外周血T淋巴细胞的百分率；迟发性的变态反应；血清溶血素和抗体形成细胞功能测定。

In the first part of the study, it was demonstrated that there was only 0.1% of PCV2 antigen-containing rate in PBL isolated from PCV2-free pigs and treated simultaneously with mitogen and PCV2. The results of both MTT assay and blastogenesis indicated that PCV2 could reduce the responsiveness of PBL to mitogen stimulation, but the results of survival and apoptotic rates indicated that PCV2 had no effects on the viability of PBL.

首先，在第一阶段实验中针对健康无PCV2带原的猪只进行测试，当同时对其PBL以致裂原刺激与PCV2攻毒处理后，其PBL中仅0.1％的细胞呈现PCV2抗原阳性；藉由MTT与blastogenesis分析，均显示PCV2可以降低PBL对於致裂原刺激的反应，然而PCV2对於PBL的存活率或细胞凋亡率则无显著影响。

Methods The inter-leukin2activity was observed by MTT colormietric assay,the interleukin2receptor expression of lymphocyte mem-brane was examined by immunofluoresence technique and lymphocyte blastogenesis in peripheral blood was measured by morphologic observation.

通过体外实验，运用MTT比色法、免疫荧光技术、淋巴细胞转化试验等实验方法，检测白细胞介素2活性、淋巴细胞膜白细胞介素2受体含量及外周血淋巴细胞转化功能。

Experiments on decalcification and activation of osteoinductive ability, comparison between the osteogenesis of demineralized bone matrix in orthotopic and in heterotopic sites, and correlation between immune response to allograft of bone and osteoinductive activity of the graft, were reported in this paper. 1. Syngeneic deminerolized bone matrix and the mixture of DBM with bone ash or acid-soluble protein extracted from demineralization was implanted into muscle pouch of mice, subsequently, the inhibition of DBM osteoinduction by bone ash or acid-soluble protein was demonstrated with histological and by means of alkaline phosphatase assay.
