Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87~5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.
以性成熟公猪睾丸和外周血为材料,采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体,通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究,发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87~5.98);同时以12号染色体为例,比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带,表明染色粒结构带比中期染色体G-带带纹丰富,而与早中期G-带带纹吻合。

Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

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。
