Chloral hydrate(CH), an intermediate metabolite of trichloroethylene(TRI) is reduced to trichloroethanol(TCE-OH), and is oxidized to trichloroacetic acid(TCA) by the nicotinamide adenine dinucleotide(NAD)-dependent enzymes such as alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) in liver. This study was performed to find out the change of activity of ADH and ALDH with increasing amount of TRI. Intraperitoneal injection of TRI were done to the male Sprague Dawely rats(mean body weight, $170{\pm}10g$) in com oil at the dosage of 150, 300, 600 mg/kg for 2 days. The results of experiments are following : 1. The contents of xenobiotic metabolic enzymes in liver are tended to be decreased with increasing amount of, but not significantlly (p>0.05). 2. Activity of ADH in microsome is decreased(p<0.05), and activity of ALDH is increased with amount of TRI(P<0.05). 3. Total trichloro-compounds(TTC) concentration in urine are increased with amount of TRI, but the ratio of between the TCE-OH and the TCA were not shown any critical change. These results suggests that the ALDH in microsome may be related to metabolism of TRI, but ADH was nothing less than the effected to metabolism of TRI.

The objective of this study was to determine the processing conditions for salt dried rockfish Sebastes schlegeli by sun drying and cold-air drying, as measured by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity. We processed salt dried rockfish samples. The salinity of rockfish samples was within 1% following salting with 25% salt brine for 3 h. The moisture content of salt dried rockfish was found to reduce linearly from 70.12 to 39.5 g/100 g over the same time interval. The water activities of salt dried rockfish by sun and cold-air drying were 0.94 and 0.87, respectively, after three days of drying. Acid values (AV) were 10.71 and 5.96 mg KOH/g, respectively, after the three day drying period. The ADH activity in a water extract from salt dried rockfish following sun and cold-air drying for 24 h was 228.5% and 226.1% at 13.3 mg/mL, respectively, and was higher than that when drying lasted for 48 and 72 h. The ALDH activity was not affected but both ADH and ALDH activity tended to decrease as the drying time increased from 24 to 72 h. The conditions of processing for the best quality of salt dried rockfish were determined to be drying with a cold-air system for 24 h. These results indicated that water extracts from salt dried rockfish have valuable biological attributes owing to the metabolizing of alcohol and can provide useful information for the design of drying systems for salt dried rockfish.

Yeast alcohol dehydrogenates and ginseng saponin interaction has been investigated to understand the non-specific enzyme stimulating effect of the saponin of Panax ginseng C.A. Meyer. It was confirmed that several amphiphiles such as sodium dodecyl sulfate(SDS), Triton X-100, sodium taurodeoxycholate (Na-TDC) as well as ginseng saponin mixture and purified ginseng glycosides lowered Km values of yeast alcohol dehydrogenase (ADH) for ethanol and NAD in the presence of the above amphiphiles suggesting that the surface activity of the amphiphiles might play a significant role in the ADH catalyzed reactions. Conformational change of yeast alcohol dehydrogenase in the presence of the above amphiphiles at their optimal concentration for the maximum activity was studied. Circular dichroism (C.D) spectrum of yeast ADH showed that the conformational change of the enzyme occurred in the presence of above amphiphiles. Fluorescence data also showed that the hydrophobic area increased in the presence of above amphiphiles. Examination of the interaction between ADH and ginseng saponin using radioactive saponin showed that there might be a very weak interaction between them. From the above results, it was concluded that the non-specific enzyme stimulating effect of the saponin might be due to the change of polarity of the enzyme solution in the presence of the saponin.

Objectives : This experiment was conducted to verify the effects of some oriental herbs(Alny Cortex et Ramulus, Artemisiae Capillaris Herba, Aurantii Nobilis Pericarpium, Giseng Radix, Hoveniae Semen, Puerariae Flos, Puerariae Radix, and Xanthii Fructus) which have been used in the treatment of alcoholic diseases, on alcoholic metabolism, and on alcoholic liver damage. Methods : The effects of the herbs on the activities of alcohol dehydrogenase(ADH), aldehyde dehydrogenase(ALDH) were evaluated and their protective effects of liver function and cells from alcoholic damage were analysed. For the evaluation of the protective effects, the levels of glucose, triglyceride, BUN, AST, and ALT in serum of rats were measured. Results and Conclusions : It is concluded that Puerariae Radix interferes with the ADH activity directly, thereby reducing the toxicity of alcohol, resulting in enhancing alcohol-tolerance and protecting liver functions. Also Artemisiae Capillaris Herba interferes both ADH and ALDH activities. Isolation of the biologically active compounds from Puerariae Radix and its detailed characterization are matters for future research.

본 연구에서는 맥류 습해의 원인인 과습에 의한 근권의 산소부족이 맥류 뿌리의 생장 및 혐기 발효대사 효소(alcohol dehydrogenase, ADH; lactate dehydrogenase, LDH)에 미치는 영향을 조사하였다. 양액재배를 이용하여 1.5엽기 맥류 유묘에 용존산소 1.5-2 ppm 정도의 혐기처리를 1, 3, 5, 7일간 실시하였다. 혐기조건에서 뿌리의 생장은 모든 맥종에서 감소하였으며, 감소정도는 내습성이 낮은 보리가 내습성이 높은 밀과 호밀보다 낮았다. 정상조건에서 ADH 활성은 보리가 LDH 활성은 호밀이 가장 높았으나 두 효소 모두 맥종 간의 차이는 크지 않았다. 혐기처리에 의해 ADH와 LDH 활성은 모든 맥종에서 공통적으로 증가하였으며 증가 정도는 호밀과 밀에서 가장 높았고 보리에서 가장 낮았다. 혐기조건에서 이들 효소의 활성증가는 모든 맥종에서 유사하게 항시발현 동위효소의 증가 및 새로운 동위효소의 발현유도에 의해 나타났다. 혐기조건에서 ADH와 LDH 활성 증가 정도는 맥종의 재해저항성과 정의 상관관계가 인정되었다. 이러한 결과는 맥류의 내습성에 혐기 발효계 효소가 관여하고 있음을 의미하는 것으로 판단된다.

Alcohol metabolizing activity of fermented sea tangle juice (FSYJ) using Lactobacillilus brevis BJ20 were evaluated by measuring relative alcohol dehydrogenease (ADH) and aldehyde dehydrogenase (ALDH) activities. According to the results of MTI assay. the fermented sea tangle juice by Lactobacillilus brevis BJ20 appeared safe in the cytotocxity. The relative ADH activity of FSTJ showed 124% at 10 mg/mL, which increased with increasing concentration. The relative ALDH activity showed, however, insignificant difference (P>0.05) between concentrations of FSTJ up to 50 mg/mL. These results suggested that fermented sea tangle juice by L. brevis BJ20 could be used as a potential material for metabolizing alcohol.
