Results The p53 gene mutation rate of colorectal cancer was 50%. The rate of apoptosis of tumor cells having mutation of p53 gene (22.11%) was much lower than that having no p53 mutation (40.57%, P＜0.05). Heteroploid cells had been found in 10/13 tumor samples with p53 gene mutation and 6/13 samples without p53 mutation (P＜0.05). The rate of apoptosis had no difference between the heteroploid cases and diploid cases.

Result: The percentage of hyperdiploid cells, DNA Index and proliferative index were statistically higher in the vascular and the syncytial subtypes of meningioma than those in the fibrous and mixed subtypes, Also those in the severe edema group were higher than those in the moderate, mild and without peritumoral edema groups. The DNA hyperdiploidy were mostly found in the group of giant size tumor, DI and PI in the recurrent menigioma group were significantly higher than those in the nonrecurrent group.

The results indicate seawater concentration has no effect on absorbency, pH, relative density, dry matter and water contents in Aloe vera leaves. While, seawater stress causes increased MDA and membrane penetration, decreased phytochroms, prolines and NO_3~--N. It is beneficial to plant growth when irrigation was done with 10% seawater, because of higher ratio of K~+/Na~+ and lower ratio of Na~+/Ca~(2+). In addition, the polysaccharide contents in Aloe vera leaves increase twice and triplication under 25% and 50% seawater irrigation respectively, the barbaloin contents increase over triplication in var. 75% seawater and over twice in var. 50% seawater and var. 100% seawater. However, when seawater concentration exceeds 25% the growth of plant was inhibited, biomass decreased, flowering time was deferred, Ca~(2+) content decreased caused by Na~+ accumulation in leaves.

结果表明：在海水胁迫下，库拉索芦荟全叶汁的吸光度、酸度、相对密度、总固形物和水分含量总体上受海水浓度的影响不大；但芦荟叶的丙二醛含量和质膜透性增加，叶绿体色素、脯氨酸和硝态氮含量减少；在10％海水浇灌下，芦荟叶细胞具有较高的K~+／Na~+比和较低的Na~+／Ca~(2+)比，对库拉索芦荟的生长有一定的促进作用；在25％海水和50％海水浇灌下，芦荟多糖含量提高了2-3倍；在75％海水浇灌下芦荟甙含量增加了3倍多，在50％海水和100％海水灌溉下，其含量也增加了2倍多；当海水浇灌浓度超过25％后，库拉索芦荟的生长明显受到抑制，生物量降低，抽苔期推迟，同时，海水浓度的增加也导致芦荟叶中累积大量Na~+，从而使得芦荟叶中Ca~(2+)含量降低，但Mg~(2+)并没有受到海水浓度的影响；用浓度低于75％的海水浇灌库拉索芦荟可以降低剖面深度在0-100cm之间的土壤盐度；其抗氧化保护酶中超氧化歧化酶的酶活力相对保持稳定，过氧化物酶的酶活力在10％海水浇灌下明显提高，随后则下降，而过氧化氢酶的酶活力则随海水浓度的升高而下降。

It implies that the relationship between Japanese black cattle and Mongolian cattle is more distant. According to that the rate of sequence divergence of mtDNA is estimated to be 2% per million years, Haplotype II and III of mongolian cattle s mtDNA might be separate about 240 thousand years ago, which is earlier than the 10000-year history of cattle husbandry. Haplotype of yellow cattleand zebu cattle might be separate about 0.73-0.92 million years ago.

按照哺乳动物mtDNA碱基突变率每百万年2％计算，单倍型Ⅱ和Ⅲ(遗传距离为0.478％)所代表的蒙蒙古牛和日本和牛遗传多态性比较研究硕士学位论文古牛群体之间的分化时间大约24万年，这比人类驯化牛10000的历史要久远得多。I单倍型和11、m两种单倍型(遗传距离为1.467%，1.83870)所代表的牛群体之间的分化时间大约73万年至92万年前。

Result indicated the increase of destroyed zoogloea and enhancement of activities of enzymes of nitrogen-fixing, de-hydrogen as well as α-amylase, leading to a decrease of period of hydrogen-producing and an increase of rate of hydrogen-producing.

与对照组相比，可溶解性化学需氧量增加了4.5倍，溶出率提高了350.00%；COD降解率提高了12%，是自然降解率的1.19倍，产氢周期缩短至6.5d，最大产氢率为67.91mL/g，平均产氢率提高到21.6mL/g，是对照组的3.9倍，效果较好。

The seed of Camelina sativa contain 5.67% jelly which envelopes the seed and could absorb 181.31 times water. This might be the main cause that the seeds of Camelina sativa absorb more water in more rapid speed than wheat, which can explain the drought-resistance of Camelina sativa.

亚麻荠种子的外层胶质占种子总重的5.67%，可吸收181.31倍的水分，使种子在最初10min内即可吸收相当于自身重量8倍的水分，浸泡24h后吸水量达到10倍左右；而小麦种子浸泡24h后吸水量只有54.7%，据此认为这可能是亚麻荠种子抗旱性较强的原因。
