This study was designed to determine the effects of Protaetia Orientalis larva (Gory et Perchlon) on the in vivo lipid metabolism in Sprague Dawley rats with the administration of carbon tetrachloride to induce damage in the liver. At the end of 8th week, serum levels of GOP and GPT, hepatic cholesterol levels, HDL-cholesterol, triglycerides and phospholipids were determined. In addition, activities of antioxidative enzymes were also determined. The administration of carbon tetrachloride resulted in increase of serum GOT and GPT, liver triglyceride and total cholesterol. On the other hand, those fed in combination with carbon tetrachloride and Protaetia Orientalis larva decreased those lipid parameters . Carbon tetrachloride feeding resulted in decrease of liver phospholipid, whereas that of the rat fed in combination with carbon tetrachloride and Protaetia Orientalis larva was increased. In antioxidative defense system, carbon tetrachloride led to a significant decrease in activities of catalase, total SOD, Cu, Zn-SOD and glutathione-S-transferase. However, those activities of the rat fed in combination with carbon tetrachloride and Protaetia Orientalis larva was significantly increased. Hepatocytes of carbon tetrachloride administered rats showed increased lipid droplets and micro-filaments. However, those of the rat fed in combination with carbon tetrachloride and Protaetia Orientalis larva were reduced in the number and the size.

흰쥐에 에탄올을 투여해 간 손상을 유도한 후 굼벵이를 투여해 굼벵이가 혈청과 간의 지진대사에 어떠한 영향을 미치는가를 조사하였다. 혈청지질 중 에탄올에 의해 증가된 triglyceride, 총 cholesterol은 굼벵이를 섭취시킴으로써 이의 수치를 감소시켰으며 HDL-cholesterol은 굼벵이의 섭취로 triglyceride 함량은 감소되었다. GOT와 GPT의 활성은 에탄올 투여시 정상식이에 비해 유의적인 증가를 보인 반면, 굼벵이의 섭취로 유의적인 감소를 나타내었다. (p<0.05). 에탄올 추여군의 간조직 세포는 세포질에 지방소적의 축적으로 세포질의 부분적인 괴사현상이 나타났으며 조면소포체와 mitochondria의 형태적 변형이 관찰되었다. 에탄올과 굼벵이의 병용투여군은 지방소적의 크기 및 양적 감소와 세포질의 괴사현상이 약간 회복 되었으나 조면소포체와 mitochondria의 수적인 증가는 미미하였다.

This study was carried out to investigate the ecological characteristics of Protaetia orientalis submarmorea (Burmeister). The emergence period of adults is appeared from April to October, and most abundant in July∼August, once a year in the field. Hibernation took place mostly in larval stage, but some in adult stage, and were generally found in the decayed rice straws and in the soil covered with compost or similar materials with average depth of 17.6 cm The developmental characteristics in the insectary (28$^{\circ}C$, 70% RH, 16L: 8D) was investigated: the average number of eggs laid per female is 82.8, egg period 8.4 days, 1st instars of larva 10.6, 2nd 18.7, 3rd 38.1, and pupal period 35.5 days. Longevity of the adult was 135.2 days In the female and 121. 7days in the male.
