The large-scale plasma treatment of waste gas in industrial or municipal conditions requires high efficiency of plasma conversion process at high processing speed, i.e., large volumetric flow. The integration of the plasma unit into existing systems puts demands on the pipe-system compatibility and minimal pressure drop due to adoption of plasma processing step. These conditions are met at the innovative rotating electrode gliding arc plasma unit described in this article. The system consists of propeller-shaped high voltage electrode inside grounded metallic tube. The design of HV electrode eliminates the pressure drop inside the air system, contrary the plasma unit itself is capable of driving the waste gas at volumetric flow up to 300 m<sup>3</sup>/hr for 20 cm pipe diameter. In the article the first results on pilot study of waste air treatment will be given for selected volatile organic compounds together with basic characteristic of the plasma unit used.

Differences in plasma obtained from different blood groups are well etablished. For many-years AHF Concentrate Kabi has been prepared from donations of single blood group. This fact allowed examination of the effect of blood groups on the F VIII yieldin concentrates. 211 batches of these concentrates were studied, 103 group 0, 83 group A and 25 group B. Each batch was assayed twice against a large frozen normal plasma pool (-150°C) using an automated F VIIIic assay system. Statistical analysis of the results show that there is no significant difference between A and B batches and that the A and B contain 21% on average more than the 0 batches. These results agree very well with the findings in some other studies. The implications of this are twofold: Firstly it can be seen that simply by selecting only A or B plasma for F VIII recovery a significant increase in F VIII in concentrates may be achieved. Secondly, the “normal plasma unit” and the use of normal plasma pools as reference standards heavily depend on the blood groups of the donors. This was clearly demonstrated by the chance use of a normal plasma pool containing 75 %. A group as compared to the usual use of 50 %. Quality control assays performed against this pool showed an alarming drop of 10-15% F VIII content of the production batches. Therefore F VIII potency estimation given in terms of normal plasma units are of limited value without detailed specification of the donor blood groups.

In Hydra adjacent epithelial cells are bound firmly to each other by desmosomes of a type not described in detail hitherto. The most prominent feature of these desmosomes is the presence of a series of parallel lamellae which bridge the intercellular space and connect the two apposed cell surfaces directly. These structures, here termed intercellular attachment lamellae, display two peaks of density about 50 A apart. These dense lines appear in some instances to be continuous with the outer dense components of the plasma unit membranes of the attached cells. The presence of prominent lamellae in intercellular attachments is sufficiently distinctive to deserve special terminology; accordingly, the term septate desmosome is proposed. It is noted that septate desmosomes may have been seen in other animals in instances where published electron micrographs show cross-striations or prominent connections in regions of intercellular attachment. It is suggested that septate desmosomes in Hydra, in addition to binding cells firmly to each other, form barriers to the movement of water into intercellular spaces and thus help to protect the organism's internal environment. Observations on the use of phosphotungstic acid for improving contrast in materials embedded in epoxy resins are also recorded.

The binding property of ionic indium (In3+) with plasma transferrin was utilized for determination of plasma volumes (PV) of whole body and individual organs in small animals. Plasma transferrin from a donor rat was labeled with 15–17 muCi 113mIn/ml plasma and injected into the tested rats. PV were determined either by extrapolation to the dilution at time zero (for whole animals) or by calculation of the ratio, organ radiation: radiation of a plasma unit volume (for organs). The reliability of the method for determination of whole-body PV was ascertained by comparing the results obtained with those obtained simultaneously by the Evans blue dilution method. Whole body PV values obtained by the two methods were similar, with a correlation coefficient (r) of 0.997. The short half life of 113mIn enables it to be used with other nuclides which have similar or different energies in the same sample; indium radiation was counted first and after it had disappeared the activity of the other nuclide could be measured.
