Eighteen patients with recent ischemic stroke were compared with an equal number of matched controls. Standardized suspensions of red cells as well as of red and white cells were filtered in a new filtration apparatus capable of discriminating between cell deformability and filter occlusion. Results show that red cell deformability, although slightly lower than in controls, is not significantly...

The haemorheological parameters haematocrit (Hct), plasma viscosity (PV), red cell aggregation (RCA), red cell filterability (RCF), apparent whole blood viscosity (WBV), and fibrinogen were measured in 31 patients with retinal artery occlusion (RAO), 25 patients with anterior ischaemic optic neuropathy (AION), and 19 patients with giant cell arteritis (GCA). The patient groups were compared wit...

A microorganism cultivated in the course of experiments with the virus of hog cholera shows the following points of interest. It is pleomorphic in extreme degree. Among the forms are coccoid and bacillary bodies at the lower limits of visibility. The culture can be completely regenerated after filtration through some Berkefeld N filters although these retain Bacillus abortus (Bang). The culture...

The effect of pressure, solids concentration and volume slurry on total two-phase filtrate volumes was investigated to establish optimum conditions for routine laboratory filtration. Full factorial design with three levels utilized obtain 27 unique experiments. used prepared by mixing crushed sieved bentonite clay 75 microns distilled water at different concentrations as obtained from the exper...

The possibility of using a membrane electrolytic cell for the electrochemical oxidation Fe(II) and purification from impurities real industrial solutions obtained by atmospheric leaching low-grade zinc concentrates is considered. average indicators carrying out electrooxidation process are given. principal conditioning sulfate solution hydrolytic with preliminary iron in an anion-exchange MA-41...
