摘要:
The present invention provides a genetically engineered fusion protein consisting of hEGF that is internalized inside of the cells after tracing down the cancer cells expressing hEGF receptors and human angiogenin that is cytotoxic by degrading ribonucleotide upon internalization, a process for preparing a fusion protein in a large quantity by transforming E. coli with the expression vectors containing the gene encoding the fusion protein, and pharmaceutical application of the fusion protein as an anticancer agent. All components of the fusion protein form no antibodies and exhibit no immunotoxicity since they are derived from human. Each component alone is inactive to the cancer cells, however, once they are fused together, they kill the cancer cells selectively with a difference of 1000 fold in IC50 in spite of its low molecular weight. Therefore, the fusion protein of the present invention is capable of treating the cancer expressing hEGF receptors at high level without showing toxicity.

A fuel-fired, forced draft air heating furnace has a draft inducer fan disposed in a vestibule chamber having an exterior wall with an air intake opening therein. During operation of the draft inducer fan its motor is cooled by combustion air drawn inwardly through the air intake opening. To enhance the combustion air cooling of the draft inducer fan motor, a deflection plate is supported within the vestibule chamber in an inwardly spaced apart, facing relationship with the air intake opening. A portion of the combustion air flowing inwardly through the air intake opening impinges on and is redirected by the plate toward the motor via a substantially unenclosed flow path within the vestibule chamber.

The present invention relates to a drum magazine, and more particularly, to a drum magazine in which a wheel cover, which is configured to provide an elastic force via a mainspring to a bullet guide unit configured to elastically support a bullet loaded in a drum at a loading hole which is an inlet of the drum, is rotatably disposed at an outer surface of the drum, wherein, at the time of loading, an elastic latch unit is elastically engaged with an inner ring gear of the wheel cover and allows rotation of the wheel cover only in one direction so that a loading space at an entry of the loading hole that is provided due to arbitrary rotation of the wheel cover in the one direction is maintained as it is even when a user removes his or her hand from the magazine, and, after the loading is completed, a latch control unit configured to disengage the elastic latch unit and the inner ring gear is operated so that an elastic restoration force of the mainspring, which is accumulated due to the loading, is transmitted to the bullet guide unit and the loaded bullet is elastically supported at the loading hole.

An unvented gas log set for an unvented fireplace. The unvented gas log set includes a log supporting frame, simulated logs operatively connected to the frame, a flame-producing burner in spaced relationship with the logs, and a pilot for the burner. The unvented gas log set utilizes a single, common fuel pressure regulator to regulate fuel from a source pressure to a reduced operating pressure for both the pilot and the burner. The unvented gas log set may also utilize a burner holder attachable to the log supporting frame for mechanically holding the burner against the log supporting frame to maintain the spaced relationship of the burner with the logs during operation.
