冰冻

Objective The origin and the nature of the Hodgkin and Reed-Sternberg cell of Hodgkins lymphoma has been attracting a lot of medical researchers engaged in studying it,for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells.Great improvement has been made since a new method of isolation of single H/RS cells from a frozen section had been set up by KUppers in 1994,and many studies have approved of the B-cell derivation of H/RS cell.lt has been reported that H/R-S cells might partly be originated from B-cell in our research before,but at the same time,we also found that only 18.8% of H/RS cells express CD20,31.3% of immunoglobulin heavy chain rearrangement have been revealed.

目的 霍奇金淋巴瘤(Hodgkins lymphoma，HL)由于它的恶性肿瘤细胞—H／RS细胞一般只占肿瘤组织的极少部分(不到1％)，且散在分布在背景细胞间，因此对于H／RS细胞的来源和性质研究一直是人们探索的目标。1994年德国科隆大学Kūppers等发展了一种从冰冻组织切片上用显微操作仪挑取单个H／RS细胞的显微切割方法进行H／RS细胞基因分析后，人们对H／RS细胞来源的研究有了突破性的进展，多数支持B细胞来源。

Materials and Methods : Serum samples were collected from out-patients and in-patients with confirmed hysteromyoma in our hospital and stored at freezing temperature (- 20℃) to be tested; the change of SOD activity was detected with hydroxylamine method and the serum MDA level was measured with TBA method; in the meantime, 20 health women were taken as the control group.

材料与方法：收集本院门诊和住院病人经病理确诊为子宫肌瘤患者的血清，-20℃冰冻保存待测，分别采用羟胺法测定血清超氧化物歧化酶活性的变化，采用TBA法测定血清丙二醛的水平，同时以23例健康人作为对照。

The strange thunder is made by the fall of sections of ice formed of spray that is frozen on the face of the cliff along the sides of the Upper Yosemite Fall... This frozen spray ①gives rise to one of the most interesting winter features of the Valley-a cone of ice at the foot of the fall, four or five hundred feet high.
