Toluene, alcohol및 vinylester류 등을 함유하고 있는 bond를 이용하여 휘발성 물질이 생체에미치는 영향을 관찰하기 위하여 rat에 일정 농도의 bond를 일정 시간 흡입시킨 뒤 각 조직에대하여 효소의 생화학적 시험과 celluloseacetate electrophoresis를 실시하여 다음과 같은 결과를얻었다. 1. Bond 흡입은 시간이 증가함에 따라 혈청, 심장, 신장, 근육, 뇌의 ChE 활성을 억제하였으며특히 폐와 간장의 ChE활성에 가장 큰 영향을 나타내었다. 2. Bond 흡입에 의해 혈청 및 각 조직 중에서 LDH활성이 증가되었으며 특히 폐와 심장,근육에서 그 영향이 현저히 나타났다. 3. Celluloseacetate electrophoresis를 통한 각 조직의 LDH isozyme pattern에는 차이가 나타났으며 bond 흡입에 의해 band의 소멸과 선명도의 감소가 일어 났는데 특히 폐에 대한 독성이가장 현저했으며 근육에 대한 독성도 큰 것으로 나타났다. Acute poisoning with organic solvents and other volatile compou-nds now usually follows deliberate inhalation(volatile substance abuse) or inges-tion of these compounds. The effect of bond inhalation was analyzed for serum, liver, lung, brain,heart, kidney and muscle. And the observations are revealed on rat cholinesterase activity, lactatedeh-ydrogenase activity and electrophoretic pattern of lactatedehydrogenase isozyme. The results are as follows ; 1. The rat cholinesterase activity on serum, heart, muscle, kidney and brain showthe decrease by increasing of inhalation time of bond, in particular the lungand liver cholinesterase activity was greatly affected. 2. Bond inhalation brough out the lactatedehydrogenase activity increased ofthe serum and the tissues and had an important effect especially in both thelung and muscle lactatedehydrogenase activities. 3. Each tissue was found to have a characteristic distribution of lactatedehydro-genase isozymes on celluloseacetate elelctrophoresis and the development ofinhalation time is shown the disappearence and diffusion of band.

In order to observe hydrological characteristics in the Gulf of Yoeng-il, measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratification in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August, on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19℃, but the water below a depth of about 30m drastically drops to 4℃. It is indicative of invasion of water mass from cold current or deep sea.

This study was attempt to evaluated the effect of Bupleuri Radix extract and Scutellariae Radix extract as the hepatotropic agents. In addition, we measured the relative effectiveness of drug combined treatment in comparison to that of alone treatment. The results are as follows ; 1. Serum and liver AST, ALT activities and liver bilirubin content of B(a)P treated group were significantly increased in comparison to normal group. After administration of Bupleuri Radix extract these enzyme activity and bilirubin content were decreased. 2. Scutellariae Radix extract decreased the increase of serum and liver AST, ALT, liver LDH activities and bilirubin content in B(a)) treated group. 3. After combined treatment of Bupleuri Radix and Scutellariae Radix extract, the serum and liver AST, ALT activities and liver bilirubin content were significantly decreased in comparison to that of drug alone treatment. 4. Buplerui Radix extract prevented the leakage of serum and liver total cholesterol, serum phospholipid and triglyceride levels caused by B(a)P treatment. 5. Scutellariae Radix extract prevented the leakage of serum and liver triglyceride and liver total cholesterol levels caused by B(a)P treatment. 6. After combined treatment of Bupleuri Radix and Scutellariae Radix extract, the lipid accumulation of serum and liver was significantly decreased in comparison to that of drug alone treatment. 7. The hepatotropic effect of drug extracts against B(a)P induced hepatotoxicity was superior to combined treatment of Bupleuri and Scutellariae Radix extract and after-treatment in comparison to that of alone treatment and pretreatment.

바이오매스로부터 생산한 바이오차에 의한 수질오염물질 흡착 : Adsorption of Water Pollution by Biochar Produced from Biomass

박윤,정수연,정은서,신윤정,이은주,이재원 전남대학교 농업과학기술연구소 2022 농업생명과학연구동향 Vol.60 No.-

Biochar is produced from lignocellulosic biomass (wood, agricultural and forestry waste, etc.) through thermal decomposition at high temperature. Water pollution (pesticides, dyes, heavy metals, and volatile organic compounds [VOCs]) can be efficiently removed by biochar. In particular, waste biomass is typically used as fuel or thrown away; thus, it is necessary to determine a valuable utilization for it. The process of biochar production is simple and suitable for the production of porous structures. In this paper, 1) biochar production and its characteristics based on biomass types, 2) research trends on the adsorption of water pollution (pesticides, dyes, heavy metals, VOCs) on biochar, and 3) expected effects are discussed.

본 연구는 QSAR을 이용하여 HIV-1 RT의 한 종류인 TIBO와 HEPT의 구조와 활성간의 상관관계를 설명하였다. 좋은 QSAR 모델은 통계적인 수치와 예측 정도를 모두 만족시켜야 한다. 생성된 모델과 수식을 통해 HEPT 유도체는 소수성이 활성과 관련이 있는 반면, TIBO 유도체는 소수성과 비편재화, 물 굴절도가 활성도와 관련이 있음을 알 수 있었다. 이러한 결과는 TIBO와 HEPT 유도체의 구조적인 특징을 파악하는데 유용하며, HIV-1 RT 억제 과정의 이해를 돕는다. 따라서, 본 연구를 통해 좀 더 강력하고 새로운 HIV-1 RT inhibitor를 제안할 수 있다. Quantitative structure-activity relationship(QSAR) have been applied in order to explain the structure requirements of HIV-1 RT inhibitory activity of TIBO and HEPT derivatives. The best QSAR models are satisfactory in both statistical significance and predictive ability. The derived structural descriptors for HEPT indicate the importance of hydrophobic contributions toward the HIV-1 RT inhibition, but the descriptors for TIBO indicate the importance of hydrophobic, electronic and molar refractivity contribution toward the HIV-1 RT inhibition. These results can be useful in identifying the structural requirements of TIBO and HEPT derivatives and helpful for better understanding the HIV-1 RT inhibition. Eventually, they provide a beneficial basis to design new and more potent inhibitors of HIV-1 RT.

The effects of volatile substances inhalation on lactate dehydrogenase and cholinesterase in rats were investigated. Male Sprague-Dawley rats were exposed to marketed odorant, ethyl acetate and ethyl ether for 15 days. Enzyme activities were measured in serum and several tissues such as liver, lung, brain, heart, kidney and muscle to find differences of effects according to the organ. Cholinesterase activity in serum and most of tissues revealed time-dependent decrease in the case of marketed odorant inhalation. Especially in heart and kidney significant decrease was observed. Ethyl acetate exposure to rats revealed also decrease in serum and all tissues by 40% to 60%. Ethyl ether inhalation showed significant decrease by 30% to 50°,%. Lactate dehydrogenase activity was markedly increased in serum and similarly in heart, brain and kidney by exposure to marketed odorant. No changes were observed in liver. Ethyl acetate exposure to rats revealed increase in serum by about 200%, compared to normal group and in other tissues by 40% to 70% except in liver and muscle. Ethyl ether inhalation showed significant increase in serum by about 100%. There was no change in liver and slight increase in muscle.

The present study was undertaken to compare the pharmacological activity of crude Cnidii Rhizoma reported with the clinical uses in the oriental medicine. Crude Cnidii Rhizoma used for the treatment of anemia, body chill, menstural irregularity and menstural pain as hematic tonic effector, sedative, adodyne and clear extravasated blood. Therefore we tested the effects of Cnidii Rhizoma water extract on the liverprotective activities in the rats. The results obtained form liver microsomal enzyme assay, measurement of serum and liver alanine, aspartate aminotransferase and lipid accumulation indicated that Cnidii Rhizoma extract showed significant liver-protective activities against benzo(a)pyrene poisoning.
