The purpose of this study was to develop a measuring system of contact force in finger-tapping of Parkinson's disease patients and to show its effectiveness for quantitative diagnosis. This system was composed of a pair of 3-axis accelerometers, a touch sensor an analog to digital converter and a personal computer (PC). Firstly, a transfer function(More)
We studied the response time of drugs in relation to the feedback mechanism in animals. The time from drug administration to onset of loss and recovery of righting reflex or death by hexobarbital in mice were measured at several dose levels and it was demonstrate that in every case the time (t)- response rate (R) function could be expressed as: (formula:(More)
The effects of drug administration on the dams (F0) and their offspring (F1), particularly on the central nervous and reproductive functions of F1, were studied by oral administration of pentazocine HCl to rats during the perinatal and postnatal periods. No significant differences were observed between administered and control rats regarding body weight(More)
In previous literature, we reported that the rats whose dams had been administerd pentazocine HCl 200 mg/kg/day during the perinatal and postnatal periods, showed no differences between control rats in the physiological function and psychotic activity tests. Brain tissues of the rats were observed histologically herein to confirm the result of previous(More)
