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)
The purpose of this study was to estimate UPDRS finger tapping score with Parkinson's disease patients by using an artificial neural network. The measurement system was composed of a pair of 3-axis accelerometers, a pair of touch sensors, an analog to digital converter and a personal computer. Firstly, the accelerations during the finger tapping were(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)
In our studies with drug combinations, we search for mixtures which would enhance the effectiveness of the related active substances. Ethenzamide was found to possess a specific suppressive effect on the gastric damage induced by aspirin. Such effect could not be demonstrated in analgesic agents such as salicylamide, bucetin, acetaminophen and phenacetin.(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)
