In order to better understand the determinants of tree height limit,32 tall tree species such as Parashorea chinensis,Sapium baccatum,Garcinia cowa,Eucalyptus citriodora,E.grandis×E.urophylla,Albizia falcataria,Populus tomentosa,Platanus hispanica,Ginkgo biloba,Pinus tabulaeformis,Ulmus pumia,Salix gordeivii,and Elaeagnus angustifolia from typical environments such as Xishuangbanna rainforest,Guangzhou subtropical area,Zhengzhou,Beijing,Helanshan mountain and Maowusu sandland in China were studied.

为了更好地了解树高极限的限制因素，本文对全国典型水分分布区域西双版纳、广州、郑州、北京、贺兰山和毛乌素沙地等地区生长的望天树、浆果乌桕、小叶藤黄、柠檬桉、巨尾桉、南洋楹、毛白杨、悬铃木、银杏、油松、榆树、沙枣、小黄柳等32种较高的木本植物进行了研究。

Results Among the 135 cases,128 cases were breast invasive ductile carcinoma,3cases were sifter-like carcinoma,1case was medullary carcinoma,2cases were carcinoma in the suit and 1case was fibroma with sarcomatous change.

结果 135例乳腺癌中，乳腺浸润性导管癌128例，筛状癌3例，髓样癌1例，小叶癌原位癌2例和纤维腺瘤伴肉瘤变1例。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。
