  • Publication number: 20040058363
    Abstract: A method of estimating a risk of the expression of an adverse drug reaction caused by the administration of irinotecan; and a method of reducing the adverse drug reaction caused by the administration of irinotecan. A polymorphism on the basis of a difference in the repeating numbers of TA repetitive sequences in the promoter region of UGT1 gene and two types of polymorphisms (bases at the 211- and 686-positions) on the basis of single nucleotide polymorphisms in the exon 1 are analyzed. Based on the analytical data, the risk of the expression of an adverse drug reaction caused by the administration of irinotecan is estimated. Further, the administration doses of irinotecan is designed for individual patients depending on the risk of the expression of the adverse drug reaction, thereby reducing the adverse drug reaction cased by the administration of irinotecan.

  • Patent number: 4931796
    Abstract: In a digital-to-analog conversion circuit, a level detector is used to determine when the digital signal is lower than a predetermined value. When a predetermined time has expired, after the level detection, an inversion detector detects an inversion in polarity of the digital signal. As a result, a control signal is produced to shift the digital signal input to the digital-to-analog (D/A) converter and to attenuate the output analog signal.
