Abstract: Provided is a refrigerator including: a body; a first storage compartment and a second storage compartment; a cold air generating unit; and a duct unit installed in front of the evaporator in the first storage compartment and including a first flow path on which the cold air is moved into the first storage compartment, a second flow path on which the cold air is moved into the second storage compartment, a first blower fan sending the cold air to the first flow path, a second blower fan sending the cold air to the second flow path, and a guide duct that partitions off the second flow path, wherein at least one cold air flowing portion is formed in the guide duct so that the first flow path and the second flow path are in communication with each other through the at least one cold air flowing portion.

Abstract: The disclosed invention relates to a novel rPLA2 enzyme, it's antibody and use and the preparation method. The purified enzyme, derived from RBC cytosol, produces arachidonic acid dependently to calcium ion, has 42 kDa of M.W. determined by SDS-PAGE analysis, shows its isoeletric point at the pH ranging 3.9 to about 4.1 in electrophoresis analysis, has maximum activity at the pH ranging 9.5 to 10 and has its specific activity of 5.6 nM/min/mg. The antibody of disclosed invention reacts with the enzyme rPLA2 only and rPLA2 is inactivated by EA4 compound, rPLA2 inhibitor. The disclosed invention shows that the 42 kDa rPLA2 identified as a novel form of Ca2+-dependent PLA2 plays an important role in hemostasis, thrombosis and/or erythropoiesis through the Ca2+-dependent release of AA.

Abstract: Disclosed is a sphingomyelinase derived from the neuron membrane of the bovine brain, which is 60 kDa in molecular weight and Mg2+-dependent in activity with an optimal pH ranging from 6.0 to 9.0.
