흰쥐에게 ethanol과 xylene을 투여시 간손상 정도를 알아보기 위해 정상적인 S-D계 수컷 흰쥐를 4군으로 나누어 실험을 수행하였다. 생화학적 검사 결과에서 혈청 AST, ALT, LDH활성은 대조군보다 ethanol 투여군, xylene투여군, ethanol+xylene투여군으로 갈수록 활성이 유의하게 증가되었으며, 그 증가율은 ethanol+xylene투여군에서 가장 높게 나타났다. 산화적 손상정도를 알아보기 위한 혈청 MDA함량은 대조군보다 ethanol투여군과 xylene투여군 그리고 ethanol+xylene투여군으로 갈수록 활성이 증가되었으며, 그 증가율은 ethanol+xylene투여군에서 가장 높게 나타났다. 그러나 혈청 ALP는 대조군에 비해 모두 감소하였다. Xylene의 투여시 최종대사산물인 요 중 m-methylhippuric acid는 대조군에 비해 xylene투여군과 ethanol+xylene투여군에서 증가되었으며, 그 증가율은 xylene투여군이 ethanol+xylene투여군보다 더 높게 나타났다. 간 조직검사에서는 xylene투여군은 지방변화를, ethanol+xylene 투여군은 경도~중등도의 괴사와 염증을 보였다. 이상의 혈청학적 검사와 조직학적 검사결과 xylene 단독 투여에 비하여 ethanol과 xylene을 병행 투여했을 때 간손상이 더 크게 초래된 것으로 나타났다.

He-Ne, IR Laser가 급성 화농성 슬관절염 치유에 미치는 효과를 알아보기 위해 Sprague-Dawley계 흰쥐를 포도상 구균으로 화농성 슬관절염을 유발 4일 후 부터 1일 1회 4분 및 10분 동안 7일간 레이저로 점조사를 하였다. 레이저 점조사를 한 동물 혈액의 효소활성과 IgG의 변화를 분석하여 얻은 결과는 다음과 같다. ALT활성은 대조군과 각 실험군이 비슷한 수준을 보였다. ALT활성은 관절염군에 비해 10분 레이저군은 유의한 증가를 보였으나 4분 레이저군은 유의하게 감소하여 대조군과 비슷하였다. LDH활성은 대조군에 비하여 10분 레이저군은 유의하게 증가하였으나 관절염군과 4분 레이저군은 유의한 감소를 보였다. ALP활성은 대조군에 비하여 관절염군, 4분 및 10분 레저군이 유의하게 감소되었으나, 그러나 관절염군에 비해 10분 레이저군은 유의한 증가를 보였다. CK활성은 대조군과 관절염군이 비슷하였으나, 관절염군에 비하여는 10분 레이저군은 유의하게 증가하였고, 4분 레이저군은 유의하게 감소되었다. IgG의 변화는 관절염군에 비해 10분 레이저군은 유의한 증가를 보였으며 4분 레이저군은 비슷한 수준을 보였으나 대조군에 비하여 각 실험군이 유의한 증가를 보였다. 이상의 결과를 종합해볼 때 레이저 치료로 근육에 많이 함유하고 있는 효소들이 염증이 있는 관절염군에 비하여 10분 레저군에서 AST, LDH, ALP 및 CK활성과 IgG 농도는 유의하게 증가하였으나,4분 레이저군에서는 AST, LDH, 및 CK활성이 관절염군에 비해 유의하게 감소된 것으로 봐 화농성 슬관절염 치유에 효과가 있는 것으로 생각된다. 앞으로 화농성 관절염에 대해 얻어질 수 있는 레이저 치료효과와 치유기전, 그리고 적절한 조사시간에 대해서는 더 연구되어야 할 것으로 생각된다.

Objectives: This experiment was conducted to verify the effects of Chungganhaeju-tang(Qingganjiejiu-tang) on the alcohol metabolism and liver functions, by measuring the activity levels of ADH and ALDH, as well as glucose, triglyceride, and BUN. Damage of the liver cells caused by alcohol was determined through the examination of serum levels of AST, ALT, ALP, LDH, and uric acid. Methods: Sprague-Dawley rats were used in this experiment and the rats were divided into control and experiment groups. Chungganhaeju-tang(Qingganjiejiu-tang) extract was orally administered in the experiment group for three weeks. Each group was further classified into two sub-groups, and control group's blood was taken without oral ingestion of alcohol, while the experiment group' s blood was withdrawn after ingestion of alcohol. Evaluation of damage level was done considering the presence of extract and alcohol. Results: In this experiment, Chungganhaeju-tang(Qingganjiejiu-tang) significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde, but didn't cause significant changes in the activity of ALDH which is a catabolic enzyme. Decreased glucose level due to alcohol consumption was recovered back to the normal level and increased levels of triglyceride, BUN, AST, ALT, ALP, LDH, and uric acid were significantly reduced. Conclusions: These experiment results suggest that Chungganhaeju-tang(Qingganjiejiu-tang) inhibits the formation of acetaldehyde in the metabolism of alcohol, and affects the recovery of weakened liver functions due to alcohol.

Background and Objective : Recently it is true that increasing interest in Oriental medicine and usage of herbal medicine. On the other hand, there are many concerns about the stability of herbal medicine. So, this study is carried out to see whether or not the treatment with Sanghan-Bang(傷寒方) is effective on the liver function besides its effectiveness in treating facial palsy. Methods : We examined serum TP, Albumin, TB, AST, ALT, ALP, LDH, ${\gamma}$-GGT levels, and facial palsy states in 37 patients with facial palsy who had admission treatment in an oriental medical hospital. Results and Conclusion : 1. We found the levels of TP, albumin, TB, and ${\gamma}$-GGT had decreased statistically significant. Also, AST, ALT, LDH and ALP levels had decreased however it was not statistically significant. 2. We analyzed the herbal group that may be efficient to the liver function; Daehwang-Jae(16 case), Injin-Jae(12 case), and Chija-Jae(6 case) in this order. 3. From the eight cases using oriental medicinal concoctions using one of Daehwang, Injin-Jae or Chija as their main component, the liver function test results displayed decreasing values, re-entering into normal LFT ranges. 4. As we compared the admission House-Brackmann Scale with discharge, the treatment was efficient and statistically significant.

This study was done to investigate whether cholic acid derivatives have anti-stress activity and what is a cause of this anti-stress effect. Seven cholic acid derivatives (cholic acid, taurocholic acid, ursodeoxycholic acid, tauroursodeoxychoic acid, chenodeoxy cholic acid, dehydrocholic acid, hyodeoxycholic acid) were used, silymarin and valproic acid were used as positive controls. Stress was induced by restraint immobilization technique plus water immersion (24hrs) and adrenal weight, spleen weight, adrenal ascorbic acid, serum cholesterol, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), adrenal cholesterol, glucose and corticosterone levels were measured as stress indicators. Most cholic acid derivatives markedly decreased the adrenal weight, and TUDCA and DHCA increased the spleen weight. The restraint stress induced increments in serum LDH, ALP and cholesterol were attenuated by most cholic acid derivatives. Cholic acid, taurocholic acid and tauroursodeoxycholic acid only increased the content of adrenal ascorbate. While valproic acid showed an inhibitory effect against stress, silymarin did not. Our findings suggest that most cholic acid derivatives have anti-stress effect and that their anti-stress effect is, in part, related to choleretic activity.

The purpose this study was to investigate the influences of 5% turmeric (Curcuma longa L.) supplementation on enzyme activities such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase, lipase and catalase in serum of dyslipidemic rats. Sprague-Dawley (SD) rats (24 male) were divided into four groups, namely the ND group (normal-nondyslipidemic diet), NT group (normal-nondyslipidemic diet+5% turmeric), DD group (control-dyslipidemic diet), and DT groups (dyslipidemic diet+5% turmeric). Serum concentrations of blood urea nitrogen (BUN), creatinine and uric acid were significantly decreased (p<0.05) by turmeric supplementation diet. The activities of AST, ALT, ALP, LDH, amylase and lipase in sera of turmeric diet group were significantly decreased (p<0.05). The catalase activity in serum of turmeric supplementation group was significantly increased than dyslipidemic diet (p<0.05). In vivo experiment with dyslipidemic rats showed that ingestion of turmeric were effective in kidney and hepatic functional enzyme activities. Which suggests that turmeric material could be used for further studies as a potential source for nutraceutical foods.

The purpose of this study was to probe the influences of krill (Euphausia superba) meal with NaF oral administration on a dose-effect relationship between fluoride levels of krill meal and serum enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. There were no significant decreases in the activities of ALP, AST, ALT, and LDH in sera among krill meal diet groups (KF10, KF20, KF30). However, these groups were significantly (p<0.05) lower enzyme activities than normal diet (ND) plus NaF 10 mg group (NF). The fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in NaF 10 mg groups (NF, KF10, KF20, KF30) were significantly increased by adding krill meal in comparison with normal diet group. The results indicate that a difficult to found toxicity to the tissues from krill meal diet groups.

Toluene is mainly metabolized in liver by oxidative pathway. Oxigen free radicals occur through the process of toluene metabolism Therefore it causes tissue and cell min by the oxygen free radicals from the metabolism of toluene. Melatonin acts as a highly efficient free radical scavenger that protects cells from damage by oxygen free radicals. To test this hypothesis, toluene hepatotoxicity was induced by an abdominal injection of toluene. To see if the melatonin protects the rat's liver, melatonin was administrated orally, at the time of each toluene injection. Aspartate aminotransferase(AST), alanin aminotransferase(ALT), latic dehydrogenase(LDH) and alkaline phosphatase(ALP) levels in serum were measured to estimate hepatic function. Malondialdehyde(MDA), which gives an indirect index of oxidative injury was also measured. Hippuric acid is the last metabolic Production of toluene was measured by HPLC. There were significantly higher in AST, ALT, LDH, MDA and hippuric acid in toluene group, but there were no significant difference in melatonin group except ALT and hippuric acid. There was significantly lower in ALP level in toluene group, but there was no significant difference melatonin group, suggesting a significant hepatotoxicity due to oxygen free radicals through the process of toluene metabolism Melatonin treatment significantly protected hepatic function and free radical-mediated injury in the liver against toluene-induced changes. Accordingly, this study shows that melatonin is helpful in protecting liver injury by acute toluene intoxication.
