RESULTS: These familial keloids mainly occurred during adolescence, showing the equal chance of being affected between male and female subjects. The affected person could be heterozygous, and a child of an affected parent had a 50% chance of being affected. Thirteen subjects displayed familiar keloid, 1 suspected keloid, 2 did not present keloid as obligate carriers, and 1 did not present keloid as doubtful carrier. One pedigree displayed keloid in 3 generations, two displayed in 2 generations. The traits of familial keloids were transmitted interruptedly, revealing incomplete penetrance. The clinical phenotypes of familial keloids presented variable expression among the different affected.

In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.
研究表明:桉树不同家系间木材物理力学性质和化学组成存在差异;粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异,株间、株内木材材色存在变异;桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异,在同一家系或同一无性系中,株间和株内也存在着相同的变化规律;桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关,侵填体含物越丰富,纹孔附物越多,桉材越容易皱缩;最大瞬间皱缩是能产生更大干燥降等的临界点,在制定干燥工艺时,必须在最大瞬间皱缩发生时,采用温和条件,使已产生最大瞬间皱缩的细胞尽可能多的恢复,尤其不能使其产生永久变定;在常温条件下,影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量;而对于瞬间皱缩和最大瞬间皱缩,几乎所有细胞都参与它们的形成过程;对于易皱缩的桉树木材,间歇干燥是最有前途的干燥方法。

This study recruited 8 OI I pedigrees (including a very large OI I kindred comprising 132 members, in which 43 are patients) and 402 nuclear families of health subjects (consisting of 1,263 subjects, and each familycontains at least one female offspring aged 20-45) in Chinese Han population. 1 By performing linkage analysis in the large OII kindred to the COLlAl and COL1A2 genes. Negative LOD score of-8.50 at 9 = 0.001 was observed for the COL1A2 gene, while positive LOD score of 2.31 at 0 = 0.001 was found for the COLlAl gene.
