Abstract:
Novel TF-2 substances having carcinostatic and immunostimulating activity, which are obtained from a culture or its supernatant fluid prepared by culturing bacteria belonging to Fusobacterium genus. Said substances are useful for the treatment of cancerous diseases of the mammals including human being. This disclosure concerns such substances and a process for preparing the same and a carcinostatic agent containing the same.
Abstract:
A composition comprising a component obtained by deproteinizing an extract from the poison pouch contents of bee has an immunostimulating activity, a carcinostatic activity, an effect of enhancing the antibacterial activity of an antibacterial substance and an effect of enhancing the carcinostatic activity of a carcinostatic substance. This invention is directed to a carcinostatic, immunostimulating and antibacterial agent comprising said composition.

Abstract:
An antibacterial composition for medical use comprising 6-[-)-.alpha.-(4-ethyl-2,3-dioxo-1-piperazinylcarbonylamino)phenylacetamido]penicillanic acid or a pharmaceutically acceptable salt thereof and a .beta.-lactamase-inhibiting penicillin or cephalosporin. The composition exhibits synergistic effect which is much greater than the sum of antibacterial effects of each component used alone.
Abstract:
By mating a main part with a first prism part or second prism part, a terahertz-wave spectrometer can easily switch between optical paths of a terahertz wave T propagating within a spectroscopic prism. When the main part mates with the first prism part, the terahertz wave T incident on an entrance surface passes through a depression, so as to be reflected by an arrangement part, whereby reflection spectrometry can be performed. When the main part mates with the second prism part, the terahertz wave T incident on the entrance surface is refracted by the depression, so as to pass through an object to be measured within a groove, whereby transmission spectrometry can be preformed.
Abstract:
A laser light shaping and wavefront controlling optical system 1 in accordance with an embodiment of the present invention comprises an intensity conversion lens 24 for converting and shaping an intensity distribution of laser light incident thereon into a desirable intensity distribution; an optical modulation device 34 for modulating the laser light emitted from the intensity conversion lens 24 so as to control a wavefront thereof; a condenser optical system 36 for converging the laser light issued from the optical modulation device 34; and an image-forming optical system 30, arranged between the optical modulation device 34 and the condenser optical system 36, having an entrance-side imaging plane between a plane 24x where the laser light emitted from the intensity conversion lens 24 attains the desirable intensity distribution and a modulation plane 34a of the optical modulation device 34 and an exit-side imaging plane on a pupil plane 36a of the condenser optical system 36.
Abstract:
A developing device for an image forming apparatus may include a seal and a casing to prevent leakage of developer. In some examples, the seal member may include multiple side surfaces while the casing may include projections that may abut and contact various surfaces of the seal member. According to one arrangement, the casing may include first, second and third protrusions, where each protrusion is configured to abut and contact a corresponding surface of the seal member. Additionally, the second projection may protrude in a position inside of the first projection while the third projection may protrude in a position between the first and second projections.
Abstract:
A total reflection measurement method using a total reflection spectrometer 1 is a total reflection measurement method comprising arranging an object to be measured on a total reflection surface 31c of an internal total reflection prism 31 and measuring an optical constant concerning the object 34 according to a terahertz wave totally reflected by the total reflection surface 31c after passing the prism 31, wherein a liquid 50 incapable of dissolving the object 34 is interposed at least between the total reflection surface 31c and the object 34. A force such as an adhesion force acting between the liquid 50 and the object 34 can place the object 34 closer to the total reflection surface 31c, thereby stably generating an interaction between an evanescent component and the object 34.
