    摘要: A current measurement circuit and method for testing a semiconductor device is provided. The method includes the steps of providing a semiconductor integrated circuit device including a voltage regulating circuit, the voltage regulating circuit being activated as needed to maintain a required voltage level; monitoring the voltage regulating circuit to determine a number of times it is activated during a sample period; and comparing the number of activations to a predetermined limit whereby if the number of activations exceeds the predetermined limit the semiconductor device is defective. The current measurement circuit includes an external clock for providing a clock signal; a first counter for counting when the voltage regulating circuit is activated; a second counter for counting clock cycles of a sample period; and a register for storing the number of activations, wherein the number of activations represents a relative current consumption value of the semiconductor device.

    摘要: A method and adsorption medium for isolating and purifying enzymes from a crude enzyme solution of animal organs or tissues. An adsorption medium for bringing about the binding of a predetermined enzyme is introduced into the crude enzyme solution and is left therein until the binding takes place, whereupon the adsorption medium is removed from the crude enzyme solution and the enzyme is separated from the adsorption medium by extraction or elution with a suitable solution. The adsorption medium is in the form of membranes of human or animal erythrocytes which have been hemolyzed by osmosis. Those enzymes which have the same or nearly the same affinity as regards binding on the membranes as does the predetermined enzyme which is to be bound are separated from the membranes prior to introducing the membranes into the crude enzyme solution. The amount of the enzymes first removed that is bound being less than the amount of erythrocytes used to form the membranes.

    摘要: Loaded cells suspended in a physiological solution are prepared in a process in which their volume is expanded by osmotic pressure. Cells so prepared suspended in a physiological solution, when injected into the bloodstream of a living body are preferentially accumulated in the spleen and liver of the body, which treats them as foreign bodies, even though the original cells may have been cells of an animal of the same species. Similarly by storing the loaded cells in a solution containing substances such as glutadialdehyde, formaldehyde that react with the protein phase of membranes or which, like difluoro dinitrobenzene, react with the lipid layer thereof, the loaded cells can also be caused to be broken down by the spleen and/or liver. Premature release of the contents of the loaded cells is prevented and timely release of such contents is assured by incorporating other materials into the loaded cells during the preparation process in accordance with the related application of the same inventors, Ser. No. 859,240 filed Dec. 9, 1977, now U.S. Pat. No. 4,224,313, issued Sept. 23, 1980.

    摘要: Magnetic substances in particles of a diameter in the range between 1 and 20 nm are suspended in the physiological solution by which cells are loaded with materials when their cell membranes have increased permeability, the magnetic materials being provided in such dosing, that when the cells are loaded, separated from the loading solution and prepared for use in a fresh physiological solution, thereafter injected to a living body, they can be collected and held fast at a predetermined location, for example, at the location of a tumor, by the effect of an external magnetic field. Ferritin, magnetite, cobalt ferrite, nickel ferrite and other ferrimagnetic, ferromagnetic or even paramagnetic compounds can be incorporated into loaded cells for this purpose.

    摘要: In a method of separating ionized substances such as heavy metal ions from mixture dissolved in aqueous solution such as sea water, lake water, waste water and the like containing at least 0.5 mM ions by means of complex formers adapted to react and enter into a combination with the substances to be separated. The method is characterized primarily by adding to the aqueous solution bubbles formed by cells of living organisms the content of which has an osmolarity differing within limitation from osmolarity of the aqueous solution. The complex formers for purposes of being received through the cells are added to a solution the osmolarity of which is lower than the cell content of the cells. The addition of the complex formers to the complex former receiving solution is contained until due to the osmosis through the cell skin acting as diaphragm, in the state of equibrium between the solution in the interior of the cells and the solution containing the complex formers, the cell content practically corresponds to the solution containing the complex formers.The osmolarity of the solution containing the complex formers is increased by adding osmotically active substances selected from the group consisting of calcium ions, potassium ions, sodium ions to the osmolarity which corresponds to the osmolarity of the cell content of the originally introduced cells. Subsequently thereto the bubbles formed by the exchange of the cell content of the cells and containing the complex formers are separated from the solution containing the complex. Thereafter the thus separated bubbles are introduced into the aqueous solution until the substance to be separated from the aqueous solution and to be ionized have moved into the interior of the bubbles through the skin of the bubbles and by the complex formers have been converted into complexes which are difficult to be disassociated or dissolved whereupon the cells are separated from the aqueous solution.
