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.

1. Objectives and Methods The original insect of $Q\'{\i}C\'{a}o$ is described as the larvae of Holotrichia diomphalia Bates (Scarabaeidae) in oriental medicine literatures. Traditionally $Q\'{\i}C\'{a}o$ inhabit on rotting wood, compost, and organic debris of soil or thatched roofs. They have the very important distinguishing mark that wriggle along on their back through rotting wood, compost etc. and they never do inflict the living crops. but, Holotrichia diomphalia Bates as the $Q\'{\i}C\'{a}o$ is not right because of many questions, such as Holotrichia are the harmful insects eat into farm products, and those don't match well with korean farmers' moods if their cultivated lands are turned over for collecting $Q\'{\i}C\'{a}o$ larvae, and especially they don't go on using their back. 2. Results and Conclusions Accordingly, in the conclusion of this subject it is reported that the original insect of $Q\'{\i}C\'{a}o$ is the larvae of Korean Cetoniidae(Coleoptera; Scarabaeoidea) insects including Genus Protaetia Burmeister(Protaetia orientalis submarmorea Burmeister, P.brevitarsis seulensis Kolbe, etc.) and the larvae of Korean Cetoniinae insects. Also, those were the original larvae of $Q\'{\i}C\'{a}o$ that were applied to not only 'DongEuiBoGam' but also 'Dongyi Suse Bowon prescriptions'. Those feed on rotting wood, compost, and organic debris of soil or thatched roofs.

The aim of this study was to clarify the origins of grubs which were used in the experiments, and to determine many other effects that are now written in the classical medical and herbal books. We compared the efficacy of grubs written in the herbal and medical books on the one hand, and studied the origins of grubs used in the experiments, on the other hand. The following results were obtained. There are three kinds of grub species for medicinal uses. Holorichia diomphalia Bates mainly produced in China, Cetoniidae species mainly produced in Korea, and Protaeria brevitarsis in Korean folk remedy are three species. Grubs were used in 25 experiments. Of these experiments, Holotrichia diomphalia were used 12 times, Larve of Protaeria brevitarsis 3 times, and Protaetia orientalis was used once. So, of total 25 experiments, 36%(9 experiments) did not clarify the origins of grubs used in the experiments. Currently, the grubs, which are imported from China and used in Korea, are Holotrichia diomphalia Bates from China. Current experimental study shows that grubs have efficacy for protecting liver. So the use of grubs in folk medicine is believed to be based on the scientific evidence. Efficacy of grubs, though it is not recorded in the medical books, has the effects of anti-cancer(anti-tumor), antioxidant, and anti-diabetes mellitus. The ingredients of Holotrichia are protein, peptide, fat, enzyme, mineral, and other several nutrients. Study on the grubs so far has a tendency to be done with little focus on the differen of origin of grubs. So, from now on, it needs that the origin of grubs be clarified, and the study on the efficacy from each origin be done. Considering the effects that the classical herbal books have recorded, it is necessary that more profound study proceed to prevent and treat diseases on eyes and ears, on the basis of the fact that grub has multiple ingredients to replenish the vital essence.
