Abstract: A circuit board includes an insulating portion and a pattern portion on the insulating portion. The insulating portion includes a first insulating region and a second insulating region outside the first insulating region and spaced apart from the first insulating region with a separation region therebetween. The pattern portion includes a first pattern portion for signal transmission and a second pattern portion including a dummy pattern separated from the first pattern portion. The first pattern portion includes a first terminal portion on the first insulating region, a second terminal portion on the second insulating region, and a connection portion on the separation region and connecting between the first terminal portion and the second terminal portion. The second pattern portion includes a second-first pattern portion on the first insulating region and a second-second pattern portion on the second insulating region and separated from the second-first pattern portion.

Abstract: A circuit board according to an embodiment includes an insulating portion; and a pattern portion disposed on the insulating portion, wherein the insulating portion includes: a first insulating region, and a second insulating region disposed outside the first insulating region and spaced apart from the first insulating region with a separation region therebetween; wherein the pattern portion includes: a first pattern portion for signal transmission; and a second pattern portion including a dummy pattern separated from the first pattern portion, wherein the first pattern portion includes: a first terminal portion disposed on the first insulating region; a second terminal portion disposed on the second insulating region; and a connection portion disposed on the separation region and connecting between the first terminal portion and the second terminal portion, wherein the second pattern portion includes: a second-first pattern portion disposed on the first insulating region; and a second-second pattern portion d

Abstract: The present invention relates to an anti-cancer composition containing acridine derivatives and guanosine compounds. In the composition of the present invention, the acridine derivative and the guanosine compound are present in the weight ratio of 1:0.1-5.0, preferably 1:0.3-3.0 and more preferably 1:0.5-1.5. In the composition of the present invention, most preferably the acridine derivative is acriflavine neutral and the guanosine compound is guanosine hydrate. Although acridine derivatives and guanosine compounds used as an active ingredient in the present composition have substantially no anti-cancer effect when they are used individually, the combination of acriflavine neutral and guanosine hydrate which potentiates the effect of acriflavine neutral, i.e. the composition(AG60) according to the present invention, exhibits reduced toxicity and increased anti-cancer effect in comparison to the use of acriflavine neutral or guanosine hydrate alone.
