Activities of Preparations

In the absence of a more satisfactory basis of comparison, a few of the preparations may be compared in terms of erythrocyte response elicited by definite quantities of different products (see Fig. 3). Inasmuch as the size of response varies with the initial red blood cell level, an attempt has been made to compare cases in which the initial erythrocyte levels were about 1.2 to 1.8 million. Responses reported by Murphy (92) and Hartfall

The calculated average daily amount of material administered is recorded in the legend. The sources of these data are contained in the text. (The daily doses recorded for the curves of Jacobson and SubbaRow refer only to the amount of primary factor administered in addition, three accessory factors were administered in the 1937 curve, in a daily amount of 3.4 mg. and five accessory factors were administered in the 1940 curve in a daily amount of 6.2 mg.)

Application and Principle This procedure is used to determine hemicellulase activity of preparations derived from A.J-pergillus niger var. The test is based on the enzymatic hydrolysis of the interior glucosidic bonds of a defined locust (carob) bean gum substrate at 40° and pH 4.5. Determine the corresponding reduction in substrate viscosity with a calibrated viscometer. 

Perhaps significant is the observation that the sulfur content of the active chitosan sulfates (13-17 % for the sodium salts) is considerably higher than that of active, heparin preparations (12 %). It would be of interest to compare the activities of preparations of heparin and chitosan sulfate which have similar sulfur content and molecular weight.

Summary Stimulating effects of isopropoxygermatran (IPG) and I-etoxysilatran (ES) on liver recovery occur through activation of protein-synthesizing components, aminoacyl-tRNA-synthetases (ARSes) in particular. Increase in the activity of preparations of total ARSes has been shown. Several aspects of the mechanisms of stimulating effects of MA were discussed. 

Indium-tin oxide (ITO) glasses have also been used as support for NS-TiOz [464-467]. For instance, Peralta-Hernandez et al. [464] reported deposition of T /02-carbon nanocomposite on ITO glass plates by electrophoretic deposition (ED) method. ITO glass plates were immersed in 10 mL of a colloidal suspension of ri02-carbon nanocomposite particles. Accordingly, a 4 V potential difference was applied between a stainless steel shield and the negative ITO plate for a period of 40 s at room temperature. The distance between the electrodes was 2 cm. Fresh electrodes were placed in an oven to sinter the nanocomposite film in the air at 450°C for 30 min. Photocatalytic activity of prepared electrodes were tested for removal of Orange II [464].

When it is necessary to compare the activity of preparations of the same enzyme which may be inhibited during the course of reaction by accumulating reaction products, the inverse time-enzyme relation may be used. Here the time required to hydrolyze a given fraction of the sub-... 

The MnOx-modified cordierite-like honeycomb catalysts 2(Mgi.xMnx)0-2Al203-5Si02 (x=0-l) were prepared by mechanochemical method from clay, talk, alumina and Mn02. Catalysts were characterized by BET, XRD, XPS, and H2-TPR. Catalytic activity was studied in ammonia oxidation to NO. Phase composition, texture and catalytic activity of prepared monoliths were shown to depend on the MnOx content and preparation conditions (preliminary mechanical treatment, time and calcination temperature). The fully substituted catalyst (2Mn0-2Al203-5Si02) was shown to have the highest selectivity to NO at 900°C, atmospheric pressure and millisecond contact time.
