한국산 및 중국산 숙지황(Dried Rehmannia Radix Preparat)의 지리적 원산지에 따른 특성을 알아보기 위하여 X-선 형광분석기(X-ray fluorescence spectrometry)를 이용하여 미량 원소 함량을 측정하였다. 143종의 시료에서 검출된 K, P, S, Cl, Si, Al, Fe, Sn 등 35종의 원소를 정준판별분석한 결과 평균 판별 정확도는 92.3%로 나타났으며, 유의수준(p=)은 0.0001 미만으로 나타났다. 통계분석에 사용하는 원소수를 35종에서 8종, 3종으로 줄였을 때 판별정확도는 각각 88.1, 84.6%로 감소하는 것으로 나타났다. 중국산내에서의 판별정확도는 94.6-96.0%였으나 한국산내에서의 판별정확도는 72.5-89.9%로 나타났다.

Objectives : The aim of this study was to investigate the effects of Ginseng Radix (Panax ginseng C.A. MEY.), Zizyphi Spinosae Semen (Zizyphus spinosa HU.) and Rehmanniae Radix Preparat (Rehmannia glutinosa LIBOSCH.) on the serotonin- immunoreactivity cells in the Caudal raphe nuclei, Rostal raphe nuclei and hippocampus of the mouse brain. Methods : The mice were stressed by restraining for one hour and treated with herbal medicine by oral feeding. The mice were killed after one hour and observed by electron microscope after immunohistochemical staining. Results : In the caudal raphe nuclei of the medulla oblongata, the highest number of 5-HT immunoreactivity cells were observed at the Zizyphi Spinosae Semen-treated group, while the lowest level among the herbs treatment group was shown at the Ginseng Radix group. In the hippocampus, serotonin-immunoreactive cells were expressed significantly at the CA3 area while the lowest level of it was shown at the control group. In the midbrain, immunoreactive cells were expressed higher than other groups, while observed at the lowest level in the control group. Conclusions : The extracts of Zizyphi Spinosae Semen, Rehmanniae Radix Preparat and Ginseng Radix show a certain degree of effect on the change of serotonin immunoreactive neurons as an index of nerve disorder.
