Active component was sought among three herb medicines, which are used in combination as a traditional medicine prescribed for patients with hyperlipidemia related diseases. Antihyperlipidemic effect of this remedy has previously been shown model by the authors on the animal model. Hyperlipidemia was induced on male Wistar rats by keeping them on high lipid diet for one week, as previously described by the authors. Blood lipid profile was verified on these rats by measuring total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Then, the diet was changed to normal. At the same time, methanol extracts of Scutellaris baicalensis Georg.(radix), Coptidis japonica Makino(rhizoma) or Rhei koreanum Nakai(rhizoma) were given on daily basis, and changes in the blood lipid profile were monitered for 4 weeks. Methanol extract of Scutellaris baicalensis Georg, significantly reduced the TC value, implying the in vivo antihyperlipidemic effect.

This procedure was carried out to give a fairly reliable method for determining wood preservatives, fire retardants, and chemicals in wood products with atomic absorption spectrophotometer. While, this study was also made to obtain a relation of moisture content to the uptake of water suluble preservatives. The results are summarized as fellows: 1. This A.A.S. procedure is a fairly reliable mothod for determining the chemi- cals in the treated wood. 2. There are no definite differences between fibre saturation point and green wood condition. The uptake of water soluble preservatives was slightly decreased as the moisture content of wood increased. However, the uptake was satisfactory even in those samples which contained the highest moisture.
