Effect of cyclohexanone treatment on the activities oxygen free radical and cyclohexanone metabolizing enzyme in acute liver damaged rats, was investigated. Acute liver damage was induced in rats with pretreatment of 50% $CCl_4$ in olive oil(0.1ml/100g body wt) intraperitoneally 3 times every other day. Cyclohexanone(1.56g/kg body wt, i.p.) was administered to the animals 24 hours after the last Pretreatment of CC1$_4$. Rats were sacrificed at 4 hours after injection of cyclohexanone. On the basis of liver weight/body weight(％), serum levels alanine aminotransferase activity and hepatic protein content, cyclohexanone treatment to acute liver damaged animals led to the more enhanced liver damage. On the other hand, injection of cyclohexanone to the rats led to the increased activities of hepatic cytochrome P-450 dependent aniline hydroxylase and xanthine oxidase. Furthermore, by treatment of cyclohexanone to the acute liver damaged rats hepatic xanthine oxidase activity was more increased than the $CCl_4$ treated rats. In case of oxygen free radical scavenging system, the hepatic glutathione content and the activities of hepatic glutathione S-transferase, catalase, superoxide dismutase were generally increased by injection of cyclohexanone to rats, and the hepatic glutathione content, catalase and alcohol dehydrogenase activities were more decreased in liver damaged rats by the treatment of cyclohexanone. In conclusion, the cyclohexanone treatment to acute liver damaged rats led to enhancement of liver damage that may be due to oxygen free radical together with cyclohexanone.

BACKGROUD/OBJECTIVES: Turanose, ${\alpha}$-D-glucosyl-($1{\rightarrow}3$)-${\alpha}$-D-fructose, is a sucrose isomer which naturally exists in honey. To evaluate toxicity of turanose, acute and subchronic oral toxicity studies were conducted with ICR mice. MATERIALS AND METHODS: For the acute oral toxicity study, turanose was administered as a single oral dose [10 g/kg body weight (b.w.)]. In the subchronic toxicity study, ICR mice were administered 0, 1.75, 3.5, and 7 g/kg b.w. doses of turanose daily for 13 weeks. RESULTS: No signs of acute toxicity, including abnormal behavior, adverse effect, or mortality, were observed over the 14-day study period. In addition, no changes in body weight or food consumption were observed and the median lethal dose (LD50) for oral intake of turanose was determined to be greater than 10 g/kg b.w. General clinical behavior, changes in body weight and food consumption, absolute and relative organ weights, and mortality were not affected in any of the treatment group for 13 weeks. These doses also did not affect the macroscopic pathology, histology, hematology, and blood biochemical analysis of the mice examined. CONCLUSION: No toxicity was observed in the acute and 13-week subchronic oral toxicology studies that were conducted with ICR mice. Furthermore, the no-observed-adverse-effect level is greater than 7 g/kg/day for both male and female ICR mice.

Objectives : Yukmijihwang-tang (YJT) is known as a tonifying formula for reinforcement of yin deficiency conditions. The present study was carried out to investigate the potential acute toxicity of YJT in ICR male and female mice. Methods : We investigated the acute toxicity about boiling water-extracted YJT. The test article was orally administered once by gavage to 20 male and 20 female mice at dose levels of 0 (control group), 1250, 2500 and 5000 mg/kg body weight. Mortalities, clinical findings, autopsy and body weight changes were monitored daily for the 14 days following the administration according to the Regulation of Korean Food and Drug Administration. Results : We observed survival rates, general toxicity, change of body weight, and autopsy. Single oral administration of YJT with different dosages, no animals died of the test drug. Autopsy of animal revealed no abnormal gross finding. Therefore, $LD_{50}$ value of YJT for ICR mice was more than 5000 mg/kg on oral route. Conclusions : These results suggest that no toxic dose level of YJT in mice is considered to be more than 5000 mg/kg. Consequently, it was concluded that YJT have no effect on acute toxicity and side effect in ICR mice.

A 36 year-old female patient with acute hepatitis B was treated with modified Chunggangunbi-tang. The patient complained of right arm and numbness, chest pain and discomfort, pain in the right chest, fever, athalpia, indigestion, fatigue, pruritus, jaundice and other minor problems. Two weeks later, symptoms has gone from severe to mild and transaminase level was lower. The medicine was prescribed for four more weeks and symptoms disappeared. The transaminase level fell to within normal range with no side effect. The Chunggangunbi-tang showed desirable effect on indigestion and more rapid recovery of liver function than previous reports on treatment for hepatitis. Finally results from clinicopathological examinations(about AST, ALT, total bilirubin, direct bilirubin, etc.) were promising. o we hope that this clinical study is helpful in treating patients with hepatic disease. Result suggests that oriental medical therapy is useful in treating acute hepatitis type B. More study and development of approach and application of this treatment for acute hepatitis type B are necessary.

Objectives: Alcohol abuse is a public issue and one of the major causes of liver disease worldwide. This study was aimed at investigating the protective effect of Ganoderma lucidum pharmacopuncture (GLP) against hepatotoxicity induced by acute ethanol (EtOH) intoxication in rats. Methods: Sprague-Dawley (SD) rats were divided into 4 groups of 8 animals each: normal, control, normal saline pharmacopuncture (NP) and GLP groups. The control, NP and GLP groups received ethanol orally. The NP and the GLP groups were treated daily with injections of normal saline and Ganoderma lucidum extract, respectively. The control group received no treatment. The rats in all groups, except the normal group, were intoxicated for 6 hours by oral administration of EtOH (6 g/kg BW). The same volume of distilled water was administered to the rats in the normal group. Two local acupoints were used: Qimen (LR14) and Taechung (LR3). A histopathological analysis was performed, and the liver function and the activities of antioxidant enzymes were assessed. Results: GLP treatment reduced the histological changes due to acute liver injury induced by EtOH and significantly reduced the increase in the alanine aminotransferase (ALT) enzyme; however, it had an insignificant effect in reducing the increase in aspartate aminotransferase (AST) enzyme. It also significantly ameliorated the superoxide dismutase (SOD) and the catalase (CAT) activities. Conclusion: The present study suggests that GLP treatment is effective in protecting against ethanol-induced acute hepatic injury in SD rats by modulating the activities of ethanol-metabolizing enzymes and by attenuating oxidative stress.

Objectives The aim of this study is to investigate the effect of Acupotomy on the pain reduction and functional improvement of patients with Acute low back pain. Methods We studied 60 patients with Acute low back pain with Numeric Rating Scale (NRS) 5 or higher in admission and had admitted to Department of Korean Medicine Rehabilitation of Daejeon University from March 1, 2017 to October 31, 2017. 30 patients had received Acupotomy combined Korean Medicine treatment(such as acupuncture, moxabustion, herbal medicine, etc) and the other 30 had received Korean Medicine treatment only. The analysis was conducted as a retrospective study which analyzes the patient's medical records. Statistical analysis was performed using the IBM SPSS Statistics 24 program. We used NRS to evaluate pain reduction, used Range of Motion (ROM) and Roland Morris Disability Questionnaire (RMDQ) to evaluate function improvement, and used EuroQol-5 Dimension (EQ-5D) and EuroQoL-Visual Analogue Scale (EQ-VAS) to assess quality of life. Finally, a five-point Likert scale was used to assess treatment satisfaction. Results The analysis revealed that patients who were treated with Acupotomy showed statistically significant NRS reduction, improvement of ROM and RMDQ, improvement of EQ-5D and EQ-VAS and satisfaction compared to those who just recevied Korean Medicine treatment. Conclusions In conclusion, we found that the Acupotomy showed a positive effect on pain resolving, functional rehabilitation and quality of life in patients with Acute low back pain.

Previous studies have shown that modified Je-Ho-Tang (MJHT) has anti-platelet effects. Je-Ho-Tang (JHT), a Korean court beverage, is a traditional Korean herbal medicine that has been used for the treatment of a disease attended by great thirst, and for prevention of illness in hot summers. We made MJHT from JHT by excluding honey. The present study was performed to determine the acute oral toxicity of crude extract of MJHT in male and female ICR mice. We investigated the in vivo single dose acute toxicity of MJHT hot-water extraction. This test was orally administered once by gavage to 20 mice of each sex received doses of 0 (control group), 1250, 2500 and 5000 mg/kg body weight. Mortalities, clinical findings, autopsy findings and body weight changes were monitored daily for 14 days following the administration. We observed survival rates, general toxicities, changes of body weight, and autopsy. No significant lethality was observed after single oral administration of MJHT at the different dosages. Autopsies on the animals revealed no gross abnormalities. Therefore, the LD50 value of MJHT for ICR mice was estimated more than 5000 mg/kg by the oral route. These results suggest that no toxic dose level of MJHT in mice is considered to be more than 5000 mg/kg. Consequently, it was concluded that MJHT have no effect on acute toxicity and side effect in ICR mice.

Objectives: Many studies have been reported the efficacy of intravenous lipid emulsion (ILE) as an antidote on acute lipophilic drug toxicity. Clozapine, highly lipophilic dibenzodiazepine neuroleptics, is an important medication in the schizophrenia therapy regimen. Acute intoxication with antipsychotics is one of the main reasons for the referral of poisoned patients to the hospital. We expected that ILE could be used for the therapy of acute clozapine intoxicated patients. Methods: We used two groups of consisting of six male rats. Both groups received a toxic dose of clozapine (40 mg/kg) intravenously, via the tail vein. After 15 minutes, they were treated with intravenous infusion of 18.6 mg/kg normal saline (NS group), or 18.6 mg/kg ILE 20% (ILE group). We evaluated blood pressure (BP) and heart rate by power lab apparatus through the tail artery, ataxia by a rat rotary circle, seizure scores and death in multiple times after starting clozapine administration. For biochemical and pathological evaluations the samples of tissue and blood were taken. Results: Our results demonstrated that ILE 20% could return hypotension-induced clozapine better than normal saline. Furthermore, ataxia and seizure have rectified more rapidly and deaths reduced. Clozapine administration causes pancreatitis and lung injury but fat emulsion did not show an optimal effect on tissue damages caused by clozapine toxicity. Conclusion: In conclusion, ILE can remove toxic signs of clozapine same as other lipophilic medicines, however, clinical uses of ILE for this intention requires more appraisement to determine the precise implication and safety.

Background: The aim of this randomized controlled pilot study was to determine the effect of trunk training in wheelchair on fall efficacy, fall risk and activities of daily living in acute stroke patients. Design: Randomized controlled pilot trial. Methods: The study included 18 patients with acute stroke who were randomly allocated to an experimental group (EG) (n=9) and a control group (CG) (n=9). Patients in the EG group received general rehabilitation therapy combined with trunk training in wheelchair for 20min, whereas CG group received general rehabilitation therapy combined with bicycle training for 20min. Both groups performed the exercise 5 times a week for 3 weeks. Outcomes were assessed using Korean-Fall Efficacy Scale (K-FES), Fullerton Advanced Balance Scale (FAB) and Korean-Modified Barthel Index (K-MBI). Results: After 3 weeks of training, both groups showed significantly improved K-FES, FAB and K-MBI (p<.05 in both groups). However, the K-FES, FAB and K-MBI in the experimental group was significantly improving than in the control group (p<.05). Conclusion: These findings indicate that trunk training in wheelchair may be effective at decreasing fall risk and improving activities of daily living in acute stroke patients. Therefore, trunk training in wheelchair may be recommended as an intervention in reducing the incidence of fall risk in acute stroke patient.
