B chromosomes do not pair with A chromosomes,they are inherited in a non-Mendelian way, exhibiting meiotic and mitotic instability andnondisjunction. Bs have little influence with the phenotype. DNA sequence differences in rye genomes (JNK population with similar geneticbackground) with and without B chromosomes were analyzed by random amplifiedpolymorphic DNA.

目前，已在约1300种植物和逾500种动物中发现了B染色体，实际含有B染色体的物种数远远不止这些。B染色体具有许多独特的性质：它独立于A染色体之外，不与任何A染色体配对，为非孟德尔遗传，具有不分离机制，不携带或极少携带核仁组织区，无影响表型的基因。

Abstract］ objective to assess the efficacy and safety of transurethral resection of prostatewith plasmakinetic technique and to improve the qualities of pkrp.methods the data of 273 patients with benign prostatic hyperplasiawere retrospectively studied baseing on the mastering of pkrp.the average maximum urinary flow rate,the average residual urinary volumeand the average international prostate symptom score were analysed.results pkrp was successfully performed on 273 patients.intraoperative blood transfusion was performed in 6 cases,no obturator nerve reflex,transurethral resection syndrome,permanent urinary incontinence occurred and no death cases occurred.the follow-up time was 2～26 months with an average of 5.63 months,postoperative average qmax increased to 15.9 ml/s,and ruv decreased to 16.0 ml/s and the average ipss was 9.compared with those of preoperation,the differences were significant.conclusion pkrp has superior tissue cutting function and hemostasis.it is suggested that transurethral bipolar plasmakinetic resection of prostate be effective and safe.

目的 探讨经尿道双极等离子前列腺切除术的安全性与有效性，提高pkrp质量。方法回顾性分析273例良性前列腺增生患者pkrp资料，比较手术前后最大尿流率、膀胱剩余尿量及国际前列腺症状评分。结果 273例手术均顺利完成，术中输血6例，无闭孔神经反射、永久性尿失禁、经尿道电切综合征及死亡病例，随访2～26个月，平均5.63个月，qmax平均增至15.9 ml/s，ruv平均降至16.0 ml，ipss平均9分。与术前相比，各项指标均有明显改善。结论 pkrp具有良好的组织切割功能及可靠的止血作用，治疗bph安全有效。

A novel Belousov-Zhabotinskii type oscillating reaction was observed in a closed serine-BrO^-~3-Mn^2^+- H2SO4 system(Ser-BZ system), which exhibited the followign characteristics:(1)Although Ser is unable to be brominated, the sustained oscillations could still be observed in the above system under batchreactor conditions even in the absence of either acetone or inert gas flow.(2)The present oscillations displayed extremely short induction period(0) and very few oscillation number(1).(3)Cl^-, acrylonitrile, or Br^- could effectively inhibit the oscillations. However, in the case when enough Ag^+ was addedinto the system to completely inhibit the oscillations in , the oscillations on the Pt-electrode could still be observed.

首次报道了间歇釜中以丝氨酸-BrO^-~3-Mn^2^+-H2SO4为体系的新型BZ类振荡反应，其特征如下：(1)虽然Ser不能发生溴代反应，但即使在无丙酮或惰性气体流时也能在间歇釜中观察到持续振荡；(2)振荡诱导期极短(～0)，振荡次数较少(1次)；(3)振荡反应受到Cl^-，Br^-，丙烯腈等的抑制；但当加入足够量Ag^+使的振荡抑制后，仍可在Pt电极上观察到振荡现象。

The results indicated that among all disposals in the small arch tunnel, the elementary florescence and prosperous florescence of the own-root plants were 3-4 days earlier, and the sub-vine female flower rate was very significantly than the other 2 grafting disposals.

结果表明：小拱棚内的各处理之间，自根苗比嫁接的两个处理初花期和盛花期均提早3~4d，子蔓第1节位雌花率也极显著高于嫁接的两个处理；雌花质量无明显差异，均低于CK。

The research on the credit of tax of tax law is made because: First, at the macro level, the rights and obligations between taxpayers and tax payees are very asymmetric.

对税法的税收信用进行研究主要基于：一是从宏观层面讲，纳税人与征税人之间权利和义务关系极不对称，纳税人享有权利过少，总是处于服从和不被尊重的地位；二是从权力层面讲，征税人自由裁量权力过大，纳税人对征税人的信任度降低，导致双方税收信用下降；三是从利益角度过分强调国家对纳税人部分权益的无偿强制占有，致使纳税人为追求利益最大化而采取法律禁止的偷、逃、骗、抗税，带来纳税人的反感和反叛，无税收信用而言。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。

When ancient nobilities construct the their tomb, must be tries their best to prevent from being stolen unturned , They went to absurd lengths to this reason , Settting various concealed weapons in the tomb, the news ambushes, megalith, quicksand, poisonous arrow, poisonous insect, snare...

古代贵族们建造坟墓的时候，一定是想方设法的防止被盗，故此无所不用其极，在墓中设置种种机关暗器，消息埋伏，有巨石、流沙、毒箭、毒虫、陷坑等等数不胜数。

The lumbar spinal cord in normal rat was immunohistochemically stained with ABC method using HAP1B antibody. Under light microscope, it was observed that HAP1 immunoreactants is mainly distributed in the pericaryon and neuropil in superficial lamella of the gray nucleus with little or no expression in other layers of the spinal horn. The substantia alba show no HAP1B immunoreactants.
