Title: Multidrug resistance inhibitor
Inventor: NAGATA KAZUHIRO
IPC: A61P37/00
Filed: 1991-09-14
Abstract: PURPOSE:To obtain a multidrug resistance inhibitor, capable of inhibiting the multidrug resistance and maintaining anticancer action essentially possessed by an anticancer agent without exhibiting any toxicity as in the case of Ca<2+> antagonistic agents which have hitherto been used as the multidrug resistance inhibitor. CONSTITUTION:A multidrug resistance inhibitor containing a flavonoid or its pharmaceutically permissible salt, especially quercetin as an active ingredient in an amount of 0.01-99wt.%, preferably 0.1-80wt.%. Since the above-mentioned active ingredient is capable of inhibiting and suppressing the action of substances for inducing or enhancing the transcription and expression of a multidrug resistance gene (MDR1), the anticancer action essentially possessed by an anticancer agent can be maintained or enhanced. Since the above-mentioned gene MDR1 expressed in tumorous cells having the multidrug resistance is inhibited at a transcription level, the inhibitor has no toxicity as in the case of Ca<2+> antagonistic agents. Furthermore, the dose of the multidrug resistance inhibitor is normally about 1-500mg per adult expressed as the amount of the quercetin and orally or parenterally administered in about 1-4 divided portions a day.

Abstract: PURPOSE:To prevent generation of quasi-stable state of an FF by providing a NOR circuit ORing the output of a delay circuit and the output of an edge detection circuit, and the FF using the output of the NOR circuit as its clock input, and an input data at its input. CONSTITUTION:A signal with waveform 0 1 0 is sent to the output E of an AND circuit 3 only when the leading edge of a data input A and a clock input B is inputted to the logic circuit in a same timing. The signal E is an input to a delay circuit 4, and then a waveform of '0 1 0' wider than the width of the signal E of the circuit 3 is sent to an output F of the circuit 4. Since the leading edge of the waveform of an output G of a NOR circuit 5 ORing an output F of the circuit 4 and the output C of the edge detection circuit 1 is delayed only when the leading edge of the data input A and the clock input B is in the same timing, the contention between the input to a clock terminal L and an input to a data terminal D is avoided by retarding the input data to an FF 6 from the data input A by a delay circuit 7.

Abstract: PROBLEM TO BE SOLVED: To hold an output current to a constant value and also to eliminate the adjusting of a circuit with respect to the variation of a source driver IC becoming a load and the change of ambient temps, etc. SOLUTION: At least either the output current Ip of a positive power source output terminal OUT+ or the output current In of a negative power source output terminal OUT- is made to have a constant-current characteristic. Moreover, a source driver has the characteristic of Ip =In . In the case a source driver IC has input terminals of control voltages (a voltage for controlling the magnitude of the output current of a source driver by controlling magnitudes of input currents of the positive and negative sources of a source driver), a control voltage Vr is automatically controlled so that at least either the output current Ip or the output current In becomes a prescribed value. In the figure A, when In is increased. I2 is decreased to lower a voltage Vr and then In decreases.  Moreover, In is decreased, I2 is increased to raise Vr and then In increses and thus In is held at a constant value almost equal to Vbe /R1 . Further, C1 is a capacitor for oscillation prevention. Furthermore, resistor for base current limitation may be inserted at a base input terminal.
