옻나무(rhus verniciflua)는 한국에서 위장병, 변비, 어혈, 구충 등에 효과가 있다고 알려져 있어 민간요법과 보양식품으로 옻닭으로 식용하고 있으나 독성 (allergy, 옻 오름) 이 심각하여 주의를 요하는 식품이다. 옻의 독성 제거방법을 사용하여 옻나무 껍질을 물로 추출한 후 항산화 작용을 갖는 수용성 물질을 분리하여 물리, 화학적 특성과 기기 분석을 통하여 (UV, IR, EI (HR)-MS, ^1HR-NMR, ^13C-NMR, elemental analyzer) 구조 분석한 결과 gallic acid (3, 4, 5-hydroxylbenzoic acid) 임을 확인하였다.

The content of high density lipoprotein incresed, and the content of low density lipoprotein decresed in lipoprotein. 3. Total cholesterol and triglyceride were decresed, and the content of phospholipid was incresed. 4. Perilla oil did not effect for changing blood glucose and Na+, K+ electrolytes. 5. Perilla oil did not effect for changing serum GOT and GPT in rabbit. 6. The activity of ACAT decresed and the activity of HMG-CoA reductase incresed. The activity of ACAT and HMG-CoA reductase in liver microsomes were reciprocal. 7. There were arachidonic acid 20:4, eicosapentaenoic acid 20:5, and docosahexaenoic acid 22:6 in the liver microsomes of rabbits. These highly polyunsaturated fatty acids were convented from linolenic acid 18:3 n-3.

In order to investigate the amino acid and fatty acid content in Thuja biotae water extract treated with alkaline, it was performed. There are 16 kinds of different amino acid and 20 kinds of different fatty acid in Thuja biotae water extract. An aspartic acid was contained 52％ and proline was contained 10％, particulary, r-aminobutyric acid was analysed.

The effects of dietary magnesium, calcium on the serum cholesterol concentration in rabbit was studied for a period of 21 days using isocalorids and isonitrogenous basal diet. It is investigated that the serum cholesterol level lowering by feeding with calcium, magnesium, sesame oil and perilla oil, did not appeared but perilla oil and magnesium feeding group appeared a little bit lowering. There was no effect for the total protein, but there was some sort of effect for albumin and globulin. Particulary, alpa-globulin was increased by calcium, magnesium, sesame oil and perilla oil feeding groups. The esterified cholesterol was increased at the magnesium and perilla oil diet group. It is also, investigate that there is almost no effect for the electrolytes concentration and transport phenomena in the cell through magnesium, calcium, sesame oil and perilla oil diet groups.

Interaction of dietary Magnesium, Calcium and Polyunsaturated fatty acid(vegetable oils)on 3-Hydroxy-3-Methylglutaryl Co-A reductase activity was studied for a period of 30 days using isocalories and isonitrogenous as a basal diet . The subject rabbits were divided into 18 feeding groups. The results are summarized as follows: 1. The ratio of α1-lipoprotein par lipalbumin is 0.34 for control group, 0.38 the highest group fed 0.1 Mg(II) 10ml plus perilla oil and basal diet, the lowest 0.25 group fed 0.1M Mg(II) 5ml plus sesame oil and basal diet. 2. The ratio ratio of α2-lipoprotein per lipalbumin is 0.64 for control group. 0.95 as the highest for the group fed 0.1M Ca(II) 15ml plus sesame oil and basal diet, 0.1M Ca(II) 5ml plus perilla oil and basal diet. 3. The ratio of β-lipoprotein per lipalbumin is 0.71 for control group, the highest 0.81 for the groups fed 0.1M Mg(II) 10ml plus sesame oil and basal diet, the lowest 0.37 for the group fed 0.1M Mg(II) 15ml plus soybean oil and basal diet. 4. In serum triglyceride, control group was 129.5mg%, the highest 155.4mg% for the group fed 0.1M Ca(II) 5ml plus sesame oil and basal diet, the lowest 85.7mg% for the group fed 0.1M Mg(II) 10ml plus soybean oil and basal diet. 5. In serum cholesterol, control group was 96.7mg%, the highest 152.5mg% for the group fed 0.1M Ca(II) 10ml plus sesame oil and basal diet, the lowest 80.5mg% for the group fed 0.1M Mg(II) 15ml plus soybean oil and basal diet. 6. In case of HMG-CoA reductase activity, control group was 0.95, the highest 0.98 for the group fed 0.1M Ca(II) plus soybean oil and basal diet. 7. Interaction between metal(II) ions and polyunsaturated fatty acid(vegetable oil) are soybean oil〉sesame oil〉perilla oil, for Mg(II). soybean oil〉perilla oil〉sesame oil, for Ca(II). Therefore, it is invetigated that the interaction between metal ion and polyunsaturated fatty acid is the higher, the cholesterol level is the lower, and HMG-CoA reductase activity is increased.
