Summary A particularly efficient removal of urea and similar substances by dialysis in an artificial kidney is obtained if both blood and dialyzing liquid are allowed to flow in countercurrent through channels a few hundredths of a mm thick and separated from each other by a membrane about 1/100 of a mm thick. In order practically to realize the flow required, about two thousand of these narrow channels, each of a length of about 2 cm, are arranged parallel to form a capillary net system.Four elements, each consisting of 2000 narrow channels, are needed in order to obtain a clearance of 80 ml/min. The quantity of blood needed to fill the elements is about 5 cm3 for each element.

Summary The scope of thin layer chromatography has been extended by developing a simple arrangement which forces solvent fronts to run over. The method was successfully applied to the separation of closely interrelated and otherwise hardly separable materials5.

Summary
G. Mansfeld demonstrated that in the serum of overheated animals a substance (thermothyrine A) is present which, injected into normal animals, decreases O2-consumption. Serum of thyroidectomized animals has no effect.Dogs and rabbits were treated daily with 0.10 g per kg methylthiouracil during 4 weeks, and were than subjected for 5 hours to a temperature of 34–35° C which raised their body temperature by 0.5–1.5° C. 2.5 cm3 of serum obtained at the end of the 5 hours period failed to reduce O2-consumption of normal rats, while sera of untreated dogs and rabbits produced after similar exposure to high temperature a fall of O2-consumption by 14–48%. It is therefore evident that methylthiouracil not only inhibits the formation of thyroxine but of thermothyrine A as well.The fact that thermothyrine A contains no iodine proves conclusively that the action of thiouracil compounds cannot be exclusively an inhibition of iodinization. 相似文献

Summary The properties and advantages of barium titanate transducers for pressure registrations have been described. If the rate of pressure change is less than 10–3 s, a barium titanate transducer with a cathode ray oscilloscope as commonly used is sufficient. Pressure changes with a duration of up to 1 s can be recorded by means of a barium titanate transducer, cathode follower with open grid, and D.C. oscilloscope. This arrangement can be adapted to the registration of processes of even longer duration by a shunt capacity. The sensativity of the transducer used was in the order of 2 V per 1 atm. 相似文献
