落实草原生态保护补助奖励政策必须抓好几项关键性工作

为保障国家生态安全,促进牧区牧业发展和牧民增收,国务院日前决定,从2011年开始,中央财政每年安排资金134亿元,在内蒙古、新疆(含新疆生产建设兵团)、西藏、青海、四川、甘肃、宁夏和云南8个主要草原省(区),全面建立草原生态保护补助奖励机制.补助奖励政策的主要内容是:实施禁牧补助、实施草畜平衡奖励、落实对牧民的生产性补贴政策、安排奖励资金.     

认识的扩散——《拇趾P纪事》松浦理英子

《拇趾P紀事》讲述了主人公一实关于性的认识的探索过程。变身后的主人公从认为同性恋变态到逐渐接受以至于亲身经历。从对性和性特征看法的单一、固守转变为多样、宽容。体现了作者对异性恋优先权的质疑,对男性中心主义的反抗,呼吁社会应对性及性特征给予更宽容的态度。

扩大禽肉出口的对策研究

禽肉是我国具有出口优势的农产品，努力扩大禽肉出口对解决“三农”问题具有重要的战略意义。自20世纪90年代以来，我国的禽肉生产和出口有了较大的发展。1992～2002年，家禽存栏由22．8亿只增加到47．4亿只，增加1．08倍；禽肉产量由454．2万吨增加到1249．8万吨，增加1．75倍。禽肉占猪、牛、羊、禽肉产量的比例由13．2％增加到19．0％。人均占有禽肉由3．9千克增加到9．8千克。     

Controlled Tissue Expansion in the Distal Extremities of Dogs

Controlled tissue expansion using a 100 cc rectangular silicone elastomer expander was performed in the mid-antebrachium and mid-crus of eight adult mixed-breed dogs. Two expander inflation schedules were followed. Group 1 dogs (n = 4) underwent expander inflation using 10 cc sterile saline every other day, and group 2 dogs (n = 4) underwent expander inflation using 15 cc sterile saline every other day until the nominal volume (100 cc) was attained. Significant mean postexpansion increases in skin surface area of 94.1 cm² (35.9%) and 108.9 cm² (37.3%) were measured in the antebrachium and crus, respectively (p < .05). In a second procedure, the expanders were removed and skin flaps were developed from the redundant tissue generated during the expansion process. Single pedicle advancement flaps and transposition flaps were used to cover surgically created defects measuring 5 times 10 cm in the antebrachium and cms. Single pedicle advancement flaps consistently measured 10 × 10 cm and could be advanced to cover defects involving one third of the mid-antebrachial or mid-crural circumference. Transposition flaps were rotated up to 170 and the donor site defects were easily closed under minimal or no tension. Complications included an abscess in one dog and seroma formation in four dogs. Differences in success or complication rates between group 1 dogs and group 2 dogs were not observed; an accelerated inflation schedule using 15 cc sterile saline every other day was recommended.     

扩大禽肉出口的对策研究(续)

从禽肉本身的特点看：禽肉是一种蛋白质含量高、脂肪含量低的肉类，二十一世纪消费者越来越关注健康食品，使得物美价廉的禽肉制品必然会成为主要的肉制品。从饮食习惯分析：长期以来国内市场可食用的禽肉制品较少，人们食用以鲜、活家禽为主，厨房事务费时费力；在日本、美国等发达国家，家庭厨房主要用来简单加工(如微波加热保温)和保鲜贮存食品(如冰箱)，人们越来越多地直接享用禽肉制品。从社会发展的趋势讲：随着我国城市化进程的加快，快餐业的迅猛发展，以及人们生活水平的提高、生活节奏的加快，卫生、快捷、营养、味美的饮食观念已逐渐占据主流地位，迫切需要大量的方便食品应市。     

低渗膨胀试验在精液品质检查上的应用

精液品质的常规检查主要检查精子活力、畸形率、顶体完整率及生存时间等指标，不足之处在于作精子活力检查时只考虑精子运动的数量而忽略了运动的质量，而且用目测法估计主观性较大；做精子形态检查时只评定精子形态是否完整而不能真实反映是否是活精子。生存时间虽较完整的反映了精子的质量，但操作起来较复杂且时间长。近年来用去透明带仓鼠卵穿透试验（HOPT）来检测精子受精力被认为是一种评价精子功能较为准确且可靠的方法，但此项技术操作复杂，难度大，尚未成为一种常规的分析方法。精子膜的形态完整性和功能活性是受精过程中的一个…
