Clear cell carcinomas that may occur in the lower urinary tract include variants of the more common cancers such as prostatic adenocarcinoma and transitional cell carcinoma as well as infrequent carcinomas such as clear cell carcinoma, which is similar to that of mullerian origin and metastatic renal cell carcinoma.8 A benign process that occasionally has been reported to show marked clear cell change is nephrogenic adenoma, a lesion that is considered a benign metaplastic process.3,5,12 Perhaps because of the great histo

透明细胞癌可能发生在较低泌尿系统包括变异更常见的癌症如前列腺腺癌和过渡细胞癌以及罕见的癌如透明细胞癌，它是相似的苗勒管起源和转移性肾细胞癌 18亿美元的良性碾压工艺，偶尔被报告显示标记为透明细胞变化腺瘤，被视为是一种良性病变的化生 process.3，5，12也许因为伟大的历史

Methods: M-CSF-dependent bone marrow cells were isolated from 5-6 weeks old mice, and cultured in the presence of MCSF (25μg/L) with different concentrations of TNF-α(0, 1, 10, 100 μg/L) for 5 days, the formation of TRAP multinucleated cells was observed. These cells were also cultured in the presence of both RANKL (30 μg/L) and M-CSF (25 μg/L) with or without 10 μg/L TNF-α for4, 5, 6 and 9 days. The number of TRAP multinucleated cells and resorption pits on dentine slices were counted under light microscope.

Nither CDMP-1, nor cryopreservation can effect cell cycle of the chondrocytes.

结果：残耳软骨细胞在体外培养时随代数增加呈异染性的糖胺多糖减少，第1、3代Ⅱ型胶原阳性细胞比例约68％/～71％，第5代为23％、显著降低；冻存后第3代为65％，与同代数的细胞没有差别，100ng/ml浓度的CDMP-1可以将第4代细胞的阳性比例维持在66％，而且冻存和生长因子不会引起细胞周期的变化。

The lipid peroxidation of S. maxima cultured in the presence of 4 to 100mg Se/L analysed showed that the contents of free radicals by EPR and malondialdehyde increased, of which the latter was the products of lipid peroxidation. These resulted in the decrease of the contents of liposoluble matter and percentage of polyunsaturated fatty acids, and the increase of percentage of saturated fatty acids. Using dimethyl sulfoxide , which was oxidized by OH·to form the stable and nonradical compound, methane sulfinic acid , as a molecular probe, we found that the contents of MSA from S. maxima growing in the presence of selenium were higher than those without selenium added, i. e. selenium in vivo was able to scavenge OH. in this alga.

对4～100mg Se/L范围内培养的S.maxima进行脂质过氧化的分析结果表明，加硒条件下藻细胞EPR自由基的含量与脂质过氧化产物的含量增加，造成细胞脂溶性物质含量和不饱和脂肪酸百分含量下降，以及饱和脂肪酸的百分含量相对上升；使用DMSO作分子探针，用它与OH·的反应产物MSA来表示藻细胞OH·含量，发现加硒条件下藻细胞MSA含量低于未加硒的，即硒在藻细胞内具有清除OH·作用。
