中国古蚤属分类研究(蚤目,栉眼蚤科)

通过对我国现有古蚤属标本和有关资料进行全面整理和系统分类研究,认为目前我国已知古蚤属共有27种,它们隶属于4个种团,分别为钝刺古蚤种团obtuspina group(1种)、鼩鼱古蚤种团soricis group(2种)、偏远古蚤种团remota group(16种)和短额古蚤种团brevifrontata group(8种),其数量已近该属世界已知种的一半.文中分别对我国已知各种古蚤的鉴别特征、生物学和地理分布状况作了介绍,并编制了各种团、种及亚种检索表.根据它们的分布特征认为我国西南部横断山区可能是古蚤属的分布中心.文中对偏远古蚤种团目前存在的问题进行了讨论.

Determination of stoichiometry of radioiodination of proteins

A sensitive method for the detection of small quantities of hydrophobic antioxidant free radical scavengers such as butylatedhydroxytoluene (BHT) and butylatedhydroxyanisole (BHA) in aqueous samples is described. The procedure involves extraction of the hydrophobic free radical scavenger into an organic solvent phase, followed by the subsequent reaction of an aliquot of this extract with the stable cation radical tris(p-bromophenyl)amminium hexachloroantimonate (TBACA). In experiments with BHT and BHA, the loss of TBACA absorbance at 730 nm was found to be linearly proportional to the amount of antioxidant added, with quantities of BHT as small as 200 pmol being easily detectable. In aqueous suspensions of dimyristoylphosphatidylcholine vesicles, assays of the aqueous BHT concentration showed that BHT partitioned strongly into the membrane phase, achieving very high BHT/phospholipid ratios. For a given concentration of BHT, partitioning into the membrane phase was greater in large, multilamellar liposomes than in either small, single-walled vesicles or in purified rat brain synaptic vesicle membranes. Direct assay of BHT and BHA in phospholipid membranes, however, was complicated by a nonspecific interaction between TBACA and the phospholipid.
