恶性肿瘤体内外生长和发展过程与细胞外基质相关性的研究

目的探讨细胞外基质在肿瘤侵袭转移中的作用。方法利用小鼠肺腺癌细胞母系ＬＡ７９５移植于Ｔ７３９小鼠皮下和肾包膜下,以及人鼻咽癌细胞系ＣＮＥ－２Ｚ移植于裸小鼠皮下等体内移植模型,通过间接免疫酶标和间接免疫荧光技术,测定纤维粘连蛋白（ＦＮ）、层粘连蛋白（ＬＮ）与Ⅳ型胶原（ⅣＣ）在肿瘤移植后不同时间的表达,并利用多种体外实验方法（琼脂糖滴瘤细胞移动实验、软琼脂上瘤细胞集落生长速度测定、斑点杂交等）,分析瘤细胞运动能力、瘤细胞集落生长速度等与ＬＮ、ＦＮ和ⅣＣ之间的关系。结果随着肿瘤的生长,ＦＮ、ＬＮ与ⅣＣ的表达均增强,且呈不同的分布;外源性ＦＮ、ＬＮ及ⅣＣ能提高瘤细胞的体外运动能力和促进瘤细胞集落的体外生长。结论细胞外基质的分布及其合成和降解的变化,与恶性肿瘤的侵袭和转移有关,对预测肿瘤生物学行为有参考价值。观察细胞外基质与瘤细胞侵袭的关系,肾包膜下移植模型较为理想     

Neutropenia, fever, and infection

With the advances in the management of various neoplastic diseases and subsequent improvement in "disease-free" states, complications of therapy--particularly, infectious complications--have evolved as stumbling blocks to survival. Among neutropenic (absolute neutrophil count below 1,000/mm3) patients with cancer, infection is the major autopsy-determined cause of death. With expected "cure rates" of childhood leukemia approaching 60 to 70 percent, it seems unreasonable to lose such patients to an infectious cause of death, yet this, indeed, happens. The purpose of this review is to (1) define the magnitude of the problem; (2) describe the various agents responsible for infections in neutropenic patients; (3) attempt to more sharply define degrees of neutropenia and mechanical defenses; and (4) consider various approaches to studying and treating these infections.     

Experimental approach to the pathogenesis of the anomalies of amniotic disease

By intra-adnexal injection of glucose in the rabbit embryo, we were able to stimulate all the anomalies associated with "Amniotic Disease". Since we were even able to obtain amniotic bands, this study provides an excellent experimental model of this disease. Resulting lesions occur early in development, corresponding to the first trimester of human gestation. All of the anomalies can ultimately be explained by the destruction of the most superficial cells: epiblastic cells of the embryo and the amnion, subjacent mesenchyme, and endothelial cells. The subsequent lack of interaction between these cells and the importance of the anatomical localizations of resulting hematomas can lead to the pathogenetic approach to this disease. In light of the present study, the disease appears to be caused by an external factor within the amniotic fluid. The exact nature of the destructive agent(s) remains a mystery in man.
