白羽瘤头鸭不同生长阶段的甲状腺活动

本文报道了用放射免疫分析法测定５７例不同日龄的白羽瘤头鸭（Ｃａｉｒｉｎａｍｏｓｈａｔａ）外用血清中Ｔ４的含量和用组织学方法检查甲状腺滤泡的发育作为甲状腺活动的指标，研究不同日龄的生长速度与甲状腺活动的关系。５７例白羽瘤头鸭的血清Ｔ４含量平均为１．３６±０．３７μｇ／１００ｍｌ，其中１—４０日龄甲状腺的分泌活动除２０日龄外，其他的均随着日龄增长而升高，分泌的高峰出现在４０日龄，以后随日龄增长而下降。４０日龄组血清Ｔ４的含量与１、１０、２０、６０、和９０日龄组比较，差异极显著（Ｐ＜０．０１），血清Ｔ４的波动与相对生长率之间有统计学强的正相关，差异极显著（Ｐ＜０．０１）。组织切片检查，刚出壳的雏鸭甲状腺滤泡小。１０—４０日龄甲状腺滤泡随日龄的增长而增大，滤泡腔被甲状腺球蛋白所组成的蛋白质凝胶的均质液所充满、着色深而均匀。６０—９０日龄鸭甲状腺滤泡虽然增大，但其内部凝胶的均质液充满不完全或空虚，着色浅而不均匀。各日龄组甲状腺滤泡的变化和甲状腺分泌的含量变化与Ｔ４的波动相一致。

Carbon sinks in mangroves and their implications to carbon budget of tropical coastal ecosystems

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. The tropical regions of the biosphere are the most biogeochemically active coastal regions and represent potentially important sinks of C in the biosphere. Rates of net primary productivity and biomass accumulation depend on a combination of global factors such as latitude and local factors such as hydrology. The global storage of C in mangrove biomass is estimated at 4.03 Pg C; and 70% of this C occurs in coastal margins from 0° to 10° latitude. The average rate of wood production is 12.08 Mg ha^?1 yr^?1, which is equivalent to a global estimate of 0.16 Pg C/yr stored in mangrove biomass. Together with carbon accumulation in mangrove sediments (0.02 Pg C/yr), the net ecosystem production in mangroves is about 0.18 Pg C/yr. Global estimates of export from coastal wetlands is about 0.08 Pg C/yr compared to input of 0.36 Pg C/yr from rivers to coastal ecosystems. Total allochthonous input of 0.44 Pg C/yr is lower than in situ production of 6.65 Pg C/yr. The trophic condition of coastal ecosystems depends on the fate of this total supply of 7.09 Pg C/yr as either contributing to system respiration, or becoming permanently stored in sediments. Accumulation of carbon in coastal sediments is only 0.41 Pg C/yr; about 6% of the total input. The NEP of coastal wetlands also contribute to the C sink of coastal margins, but the source of this C is part of the terrestrial C exchange with the atmosphere. Accumulation of C in wood and sediments of coastal wetlands is 0.205 Pg C/yr, half the estimate for sequestering of C in coastal sediments. Burial of C in shelf sediments is probably underestimated, particularly in tropical river-dominated coastal margins. Better estimates of these two C sinks in the tropics, coastal wetlands and shelf sediments, is needed to better understand the contribution of coastal ecosystems to the global carbon budget.     

常见儿科病红细胞免疫粘附功能检测的临床意义

检测儿科常见疾病患者中的红细胞免疫粘附功能发现：（１）新生儿的红细胞免疫粘附功能尚未发育完善，低于正常儿童水平；（２）急性肾炎患儿的红细胞免疫粘附功能呈现继发性增强；（３）肾病综合征、风湿性疾病、大叶性肺炎、秋季腹泻及急性白血病等患儿的红细胞免疫粘附功能呈继发性降低；（４）红细胞免疫粘附功能的变化与疾病的发展及转归有关。提示在儿科疾病的诊断和治疗中观察患儿的红细胞免疫粘附功能有重要意义。     

热胁迫对辣椒花粉发育及其生活力的影晌

用光学和荧光显微镜及扫描电镜观察等方法，研究了热胁迫对辣椒花粉形成发育、生活力、萌发率及雌性系统的影响。发现辣椒不同耐热性品种在高温胁迫下，花粉、花药发育过程出现异常，花粉生活力、体外萌发率下降，花粉管生长延迟，正在生长的花粉管伸长停滞。这些影响感热性品种比耐热性品种表现更为明显。在雌性系统中未见明显影响。

振动胁迫对杨梅果实采后衰老生理的影响

振动胁迫促进杨梅果实的衰老，表现为促进膜诱性的增加和ＳＯＤ活性与精胺含量的下降。但在振动胁迫后的贮藏初期，果实多源精胺的合成明显增加，而乙烯产生量明显降低，这可能是杨梅果实抗振动胁迫的一种应激机制。而在振动胁迫后的贮藏后期，果实的精胺含量降低，腐胺积累较多，乙烯产生量较高，表明振动胁迫最终促进果实的全面衰老。
