Decreased transport of orally administered protein into the blood circulation of developing juveniles of Japanese eel Anguilla japonica

ABSTRACT: To clarify the quantitative changes in the transport of orally intubated protein into the blood circulation as macromolecules in development, immunoglobulin Y (IgY) extracted from chicken eggs was administered orally to juvenile Japanese eel, Anguilla japonica . For the first experiment, which was performed before the commencement of artificial feeding, the oral delivery of 2.0 μg/0.1 g bodyweight of IgY resulted in a rapid increase in plasma IgY to a maximum of 2.30 μg/mL. However, the transport of IgY into the blood decreased significantly in the experiments that followed, which were performed after 12, 25 and 42 days. During this period, bodyweight increased approximately by a factor of eight, and rapid growth of the stomach was observed histologically. Possible contributions for the development of the alimentary canal to the diminishment of intestinal protein assimilation are discussed.

企业无力清偿欠薪的法律应对：基于香港的经验

1980—1982年经济危机爆发后，香港因大量企业倒闭引发欠薪浪潮，欠薪优先权机制出现失灵。以国外经验为模本，香港构设了欠薪保障基金制度。该制度依托完善的法律程序将欠薪纳入专门基金予以垫付，并逐渐提高垫付标准。这种法律设计特点鲜明，实际运行数据也证明比较成功。这为解决当前农民工极端讨薪事件频发、欠薪问题季节性爆发的顽疾，提供了极具参考价值的制度化思路。我国应当鼓励地方探索和构建企业欠薪保障制度。
