Abstract: In response to a command from the control PC 4, the first mobile terminal test apparatus 2 compresses data of test signals including a first test signal and a second test signal which are generated and encrypted, and adds a restoration parameter to a header of the compressed data. The second mobile terminal test apparatus 3 acquires the restoration parameter-added compressed data at the second port 3a via the cable 5 from the first port 2a, and restores and encrypts the data of test signals before encryption, based on the restoration parameters. Under the control of the control PC 4, the first mobile terminal test apparatus 2 outputs the data of the first test signal to the device under test W, and the second mobile terminal test apparatus 3 outputs the data of the second test signal to the device under test W.

Abstract: A novel megakaryocyte colony stimulating factor has been isolated from the supernatant of the culture obtained by cultivating a cell strain of a human large cell lung cancer. When the factor is applied to human or murine bone-marrow cells in vitro, it forms a megakaryocyte colony. Also, the factor increases the number of platelets in peripheral blood in vivo.

Abstract: .alpha.-Hydroperoxyisopropylphenyl compounds are useful as an organic hydroxyperoxide content in test compositions for the measurement of peroxide-active substances and are effectively utilized for detecting peroxide-active substances such as blood or hemoglobin (occult blood).Test devices for the detection of occult blood are constituted of a carrier in which organic hydroperoxide, coloration indicator, buffering agent, wetting agent, activating agent and stabilizer are impregnated. If hemoglobin is present in a specimen, the organic hydroperoxide is activated to produce nascent oxygen with which the indicator is oxidized and develops color.

Abstract: Hot-water extracts of the neem bark produced by treating the bark of neem with water at a temperature from 0.degree. to 40.degree. C. and subjecting the residue from said pre-extraction treatment to extraction treatment with hot water. Purification of the extract thus produced by means of alcohol precipitation or dialysis gives products of a higher purity. Moreover, treatments prior to the pre-extraction treatment with water at 0.degree.-40.degree. C. with a non-polar organic solvent having a dielectric constant of 10 or lower and a polar organic solvent having a dielectric constant from 15 to 35 yields neem extracts of a further higher purity. The hot-water extracts of the neem bark according to the present invention possess activity against mouse L-5178Y cells and transplanted sarcoma 180 tumors.

Abstract: A hot-water extract of the bark of Melia azadirachta L. is treated with a gel filtrating agent with a fractionation range molecular weight from 1.times.10.sup.3 -1.times.10.sup.5 to 1.times.10.sup.3 -1.5.times.10.sup.5. There is obtained polysaccharide N9GI from the first fraction of the three divided polysaccharide fractions. Polysaccharide N9GI further treated with a gel-filtrating agent with a fractionation range molecular weight from 1.times.10.sup.3 -2.times.10.sup.5 to 1.times.10.sup.3 -8.times.10.sup.5. There are obtained polysaccharide N9GIa and polysaccharide N9GIb respectively from the first and second fractions of the two divided polysaccharide fractions.

Abstract: Neem bark extracts produced by pre-treating the bark of neem with an organic solvent having a dielectric constant of 10 or lower, for example, benzene or ethyl acetate and subjecting the residue obtained by the pre-treatment to extraction with a hydrophilic organic solvent having a dielectric constant from 15 to 35, for example, methanol or ethanol and recovering the neem bark extracts from the hydrophilic organic extraction solvent.

Abstract: A device for culturing microorganisms includes a vessel having a mouth for containing a culture medium and a stopper member for hermetically sealing the vessel. The stopper member is provided with a through hole on its peripheral wall for communicating with the inner atmosphere of said vessel.
