정상 동물군의 GOT값 및 GPT 값이 각각 137.8$\pm$23.4 및 67.4$\pm$10.0 이었고 acetaminophen 투여군은 418.6$\pm$69.1 및 447.4$\pm$7.7로 증가하였으나 G009 투여군은 그 증가가 현저히 억제되었다. 즉 G009 10mg/kg 투여군은 GOT 및 GPT 값이 192.6$\pm$19.2 및 144.8$\pm$28.7에 그쳐 각각 GOT 및 GPT 값의 상승이 80.5% 및 79.6% 억제되었고 20mg/kg 투여군은 90.8% 및 86.6% 억제되었다. 그러나 Licovek 은 50mg/kg의 투여군에서 이와 유사한 효과가 관찰되었다. 또한 간 절편의 조직학적 관찰 결과 acetaminophen 투여 대조군이 간세포 괴사등 심한 조직 괴사를 보인 반면 G009 10mg/kg 및 20mg/kg 농도에서는 간장 손상이 매우 경미함을 확인할 수 있었다.

본 실험에서는 반SP와 thermotolerance 사이에 어떠한 상관관계가 있는지를 알아보기 위하여, 생쥐 SCK 종양세포에서 heat(45$^{\circ}$, 46$^{\circ}C$)처리가 단백질 합성과 세포의 생존에 미치는 영향을 비교하여 보았다. 그 결과 heat 처리를 받은 세포는 HS$\ulcorner$(70K, 87K)를 측이하게 많이 합성했으며, 다음 heat를 받았을 때는 높은 생존율을 꼬였다. 그리고 이러한 thermotolerance가 생성되고 감퇴되는 kinetics는 HSP가 합성되고 감퇴되는 kinetics와 연관성을 보여 주었다. 이러한 결과로 HSP는 heat shock로부터 세포를 보호하는 데 중요한 역할을 할 수 있다고 생 각된다. 아울러, glycerol을 처리하여 HSP의 합성을 봉쇄시켰을 경우에도 열에 대해 저항성을 갖게 되는 실험결과로 미루어, 세포가 갖게 되는 heat resistance에는 (1) HSP의 합성을 초래하지 않는 요인에 의해 유도되는 heatprotection과 (2) 열처리 등의 결과 합성되는 반SP에 의해 유도되는 thermotolerance의 두가지 경우가 있을 것으로 추론할 수 있었다.

The writer adopted the new correct scientific names of 46 Microlepidoptera previously incorrectly recorded in 'A List of Plant Diseases, Insect Pests and Weeds in Korea,' published by the Korean Society of Plant Protection in 1972 and 'Nomina Animaium Koreanorum Insects,' by the Zoological Society of Korea in 1968.

Herpetofauna of the Naesorak in Sorasan National Park was carried out both June 30, 1997~July 3, 1997. 6 species of 5 Families in Amphibian and 3 species of 3 families in Reptilian were observed in thes survey. It was observed relatively poor biota to Kaya, Sokri, and Chri National Park in Korea. There were three Specific Endangered Animal assigned by Minister of Environment such as Bufo stejnegeri, Rana dybowskii and Eremius argus. Especially Eremius argus was abundantly distributed around Limansuryonjang. So Limkansuryonjang should be conserve for Eremias argus's stable environmental condition.

In this paper, we described web content searching system focused on the natural monuments, the endangered and reserved wild animals, the rare wild animals relevant to CITES & IUCN red data book, and the Korean endemic species. As a result of this research, we developed system for inserting and modifying of contents and efficient web searching system on the multimedia contents.

전 세계적으로 건강, 환경보호, 윤리적 소비를 추구하는 소비자들이 증가하면서 다양한 분야에서 동물성 제품을 섭취하거나 소비하지 않는 생활방식인 비거니즘(Veganism)을 지향하는 사람들이 증가하고 있다. 한국 또한 매년 채식에 대한 관심이 높아지고 있지만 외국에 비해 채식하기에 좋은 환경은 구축되어 있지 않으며 가공식품을 구매할 경우 성분 표를 일일이 확인해야 하는 어려움이 있다. 본 연구에서는 사용자가 섭취하고자 하는 가공식품의 성분을 분석하여 본인의 채식주의자 단계에 적합한 제품인지 쉽게 판별할 수 있는 모바일 앱을 제안한다.

We were investigated the cognitive ability enhancement in rats using B. mori fibroin molecular controlled hydrolysate by preparative recycle HPLC system. Also, some of its physicochemical properties and free amino acid components were investigated, too. Nuclear magnetic resonance (NMR) spectrum are measured different pattern between high (HF) and low (LF) molecular controlled B. mori fibroin samples, respectively. The in vitro test by neuron primary cell culture are showed dependent on molecular weight (Mw) of B. mori fibroin in the order of LF > MF > HF, too. However, the memorial effects in rats by in vivo test are large dependent molecular weight on that maximum 50% than control. Also, the memorial effect was higher than the enzymatic relative and acid hydrolysate, which was 50.0$\pm$2.1 and 25.9$\pm$0.32%, respectively.

The anti-stress effects of Punica granatum L. (family Lythraceae, PG) on $H_2O_2$/corticosterone (CORT)-induced stress in cells and sleep-deprived rats were investigated. The PG extract showed neuroprotective effects in SH-SY5Y cells against $H_2O_2$/CORT-induced stress. Sleep deprivation led to behavioral, hormonal, and biochemical alterations in the animal model. The effects of P. granatum on physiological, behavioral, and biochemical parameters aggravated by sleep deprivation were investigated. Sleep deprivation impaired physiological (survival, body weight, and drowsiness scores) and behavioral (rotarod, passive avoidance, hot hyperalgesia, and Y maze) parameters as well as biochemical factors (cortisol, serotonin, dopamine, testosterone, and growth factor I contents in serum). These parameters were significantly recovered by PG extract in a concentration-dependent manner. The PG extract also enhanced catalase, superoxide dismutase, and non-enzymatic antioxidative activities such as glutathione compared to sleep-deprived rats. On the basis of these results, our findings suggest that Punica granatum prevents impairment of body functions induced by sleep deprivation and related oxidative damage.

In this study, we determined the ecological characteristics of Strix aluco, which is designated as an endangered category II species. Towards this, we identified the actual home range of Strix aluco that breed in Korea, and collected the data necessary for protecting, preserving and managing owl populations. This study was conducted from April 14 to May 20 of 2016 during the breeding season of Strix aluco as part of the 4th National Ecosystem Survey and in accordance with the Natural Environment Conservation Act. We captured and subsequently released a female owl with a total length of 423.5mm and a weight of 550g in Kyungbuk area, succeeded in tracking it for the first time in Korea and secured 6 points of direct observation and satellite tracking observation. The distance from the nest to the farthest point was 93m. As a result of the analysis of habitat points within a100m-radius during breeding period, it was established that their habitat consists of 34.2% of non-irrigated land, 30.6% of mixed forest land, 10.5% of orchard, and 9.4% of natural grassland. These findings are consistent with the previous estimate of home range studies. Further research based on follow-up studies on males or other individuals is required to develop a stronger basis for protection and conservation of endangered wildlife class II owls.

Disposing technique for dairy cattle manure using earthworms and the possibility of utilizing earthworms in poultry feed were investigated. In addition, chemical properties of manure and cast of earthworms were investigated. Temperature in the vinyl-house for earthworm nursery was able to be maintained above 0$\^{C}$ in winter and 25-28$\^{C}$ in summer. In closed-covering method, the number of escaped earthworms was the highest among three covering methods. The time was longer after manure excretion, the numbers of escaped earthworm were higher. There were some incidences of mortality of earthworm in closed-covering site. The amount of manure ingested by earthworm was increased in order of non-covering, closed-covering and gap-covering method. Fresh manure was more ingested than old one by earthworm. Earthworms reduced manure about 50% on the dry weight base and reduced total amounts of N, P$_2$O$\_$5/ and K$_2$O of manure by 41, 50 and 60%, respectively. Earthworm could be utilized by adult poultry (>60 g) for feeding. However, adverse effect of live earthworm was observed with young poultry (<450 g).
