Purpose: The purpose of this study is to provide a comprehensive overview of the various measures available for assessment of oxaliplatin-induced peripheral neuropathy (OXLIPN) and to evaluate the measurement properties of each assessment tool. Methods: A systematic review was conducted to identify existing measures for OXLIPN found in the databases of PubMed, Cochrane Library, Embase, RISS and KoreaMed. The quality of the 24 identified tools was evaluated based on their properties of measurement including content validity, internal consistency, criterion validity, construct validity, reproducibility, responsiveness, floor-ceiling effects and interpretability. Results: Ten (41.7%) of the 24 tools were identified as specific measures for assessing OXLIPN and the most popular type of measures were clinical grading systems by clinicians (58.3%) and only 29.2% of measures were identified as patient reported outcomes. The most frequently used tool was National Cancer Institute-Common Toxicity Criteria (NCI-CTC), but the validity of NCI-CTC has not been reported appropriately. Overall, the Neuropathic Pain Symptom Inventory (NPSI) received the best psychometric scores, and the Chemotherapy-induced Peripheral Neuropathy Assessment Tool (CIPNAT) and Functional Assessment of Cancer Therapy/Gynaecologic Oncology Group-neurotoxicity-12 (FACT/GOG-Ntx-12) followed NPSI. Conclusion: To select appropriate measure, evidences should be accumulated through the clinical use of tools. Therefore, practitioner and researchers are urged to report relevant statistics required for the validation of the currently used measures for assessment of OXLIPN.

The oriental medicine Jangwonhwan, which is a boiled extract of 12 medicinal herbs/mushroom, has been prescribed for patients with cognitive dysfunction and it is originally from the Korean medical text, DonguiBogam(amnesia chapter). Recently, a modified recipe of Jangwonhwan (LMK02-Jangwonhwan) consisting of seven medicinal plants/mushroom, was shown to reduce ${\beta}$-amyloid deposition in the brain of Tg-APPswe/PS1dE9 mouse model of Alzheimer disease. The toxicity of LMK02 was investigated in SD rats by oral repeated adminstration for 4 weeks and we tried to determine test does for 13 weeks repeated study. Quality control of tablet form of LMK02 was established by estimating indicative components, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelicagigas Nakai. The toxicity of LMK02 was investigated in 6 weeks old specific pathogen free (SPF) Sprageu-Dawley rats by oral administration. Each test group were consist of 5 male and 5 female and they received doses of 500, 1,000 and 2,000 mg/kg/day of test substance for 4 weeks. The clinical signs, death rate, body weight, food consumption, ophthalmic examination, urinalysis, hematological and serum biochemistry, organ weight and pathological changes were examined and compared with those of control group. Urinalysis : We observed increase of PRO(p<0.01), SG(p<0.01) in female rats of 1,000 mg/kg/day and 2,000 mg/kg/day(p<0.01). Also, we observed increase of pH and KET in female rats of 1,000 mg/kg/day(p<0.05) and of 2,000 mg/kg/day(p<0.01). WBC in female rats in 1,000 mg/kg/day and 2,000 mg/kg/day were on increase. Hematological test : We observed increase of MCV in male rats of 250 mg/kg/day. (p<0.05) Serum biochemistry test : We found increase of CHO in female rats of 2,000 mg/kg/day(p<0.05). During the experimental period, there were no animals dead or moribund. There were no treatment related changes of general symptom, food and water consumption, organ weight and autopsy According to the results of 4-week repeated dose range finding study, the highest dose was established as 1000 mg/kg for 13-week repeated dose toxicity study and we determined to put 2 more groups by common ratio two.

This study was carried out to investigate lead contamination in the leaves of roadside trees and the cause of yellow-brown symptom of leaves in Jinju and Daegu city. After the leaves were collected and dried in 105$^{\circ}C$ drying oven from September to October in 1974, the samples were used for analysis of the lead contents in 1976. The roadside trees in the two cities were mostly the four kinds of Ginkgo biloba L., Thuja orientalis L., Platanus orientalis L. var. acerifolia AIT. and Prunus pseudo-cerasus $LINDL{\times}Prunus$ subhirtella MIQ. The lead contents in the leaves of roadside trees in Daegu city was higher than that of Jinju city. The lead contamination of the evergreen trees of roadside was higher than that of the deciduous trees. In Jinju city the site of the highest contents of lead in the leaves was revealed with Jinju station(0.73ppm), the next site was revealed with the road(0.16ppm) between Namgang bridge and Jinju middle school, and the lowest site was generally beside the roads of suburbs (0.07ppm). Because of the low contents of lead in the leaves, it was found that the yellow-brown symptoms of leaves were not caused by the lead toxicity.

1. All the male students and female students who had taken these herb medicines showed a strong increase in immunity (P<0.01) and they were more effective to the male students (P<0.01) rather than the female students (P<0.05) (figure 1). Generally, immunity may be reduced at the time of fatigue and overwork but as these herb medicines have the effect of increasing immunity. Therefore, it is considered that they not only reduce the fatigue of human body but also heighten immunity against disease. 2. The students who had taken these herb medicines showed some reduction in Cortisol concentration in blood, which didn't show the difference of concentration up to statistical meaning compared to before taking the medicines (figure 2). Accordingly, it is regarded that these herb medicine drink restrained stress slightly. 3. The students who had taken these herb medicines showed some reduction in BUN concentration in blood, which didn't show the difference of concentration up to statistical meaning compared to before taking the medicines (figure 3). For the women, they restrained the toxicity of the kidneys just a little. Accordingly, it shows that these medicines are safe herb medicines without the toxicity of the kidneys. 4. The students who had taken these herb medicines didn't show the difference of concentration up to statistical meaning in sFOT and sGPT concentration in blood compared to taking them (figure $4{\sim}5$). Accordingly, it is suggested that these medicines are safe stuffs without the toxity of the liver. 5. Seven members of the university students answered to the questionaire that they were pleasant while taking the medicines and didn't feel fatigue. They answered very positively that they had better effects than before taking the medicines in many things (Refer to the Questionaire). However, one male student and two female students of them complained of temporary headache and indigestion for 2 days after taking these herb medicines but they said they had been taking cold medicines due to cold symptom before taking the medicines. Accordingly, it turns out that such temporary symptom is not irrelevant to these medicines. In conclusion, it is considered that these herb medicines have the effects of increasing immunity, restraining fatigue and stress through this clinical study carried out in simple way and that they are valuable as herb medicines without the toxity of the liver and kidneys.

Objectives : The contents of aconitine in aconiti radix lateralis preparata, purified hot water extract of Aconiti Radix lateralis preparata, and purified hot water extract of Sambutang-P that contains Aconiti Radix lateralis preparata was analyzed to compare toxicity. Toxicity of Sambutang-P that contains Aconiti Radix lateralis preparata was assessed with a single oral toxicity test on 6-week-old male and female Sprague-Dawley rats. Methods : 1. The contents of aconitine in Aconiti Radix lateralis preparata, purified hot water extract of Aconiti Radix lateralis preparata, and purified hot water extract of Sambutang-P that contains Aconiti Radix lateralis preparata was analyzed using the purity test according to the "Korean Herbal Pharmacopoeia". 2. 2,000mg/kg was injected for the single oral toxicity test of purified hot water extract of Sambutang-P that contains Aconiti Radix lateralis preparata, and the test was done for a test group (injection) and a control group, each with 5 male and 5 female rats. For 14 days after injection, rats were observed for general symptoms and changes in weight. Afterwards, blood biochemical test, autopsy, and histophathological exam of the liver was conducted. Results : 1. The contents of aconitine was 0.0785% for Aconiti Radix lateralis preparata, 0.1510% for purified hot water extract of Aconiti Radix lateralis preparata, and 0.1248% for purified hot water extract of Sambutang-P that contains Aconiti Radix lateralis preparata. 2. There was no death of either male or female rats in both the control group and the test group (injection of 2,000mg/kg). 3. No unusual symptom was observed in both the control group and the test group (injection of 2,000mg/kg). 4. No significant change in weight was observed for both male and female rats in the test group (2,000mg/kg). 5. The histopathological exam of ALT, AST, ALP, GGT and LDH showed no significant changes for both male and female rats in the test group (2,000mg/kg). 6. According to the autopsy results, no visible abnormality of organs or tissues was found in both the control group and the test group (2,000mg/kg). 7. According to the histopathological exam of the liver, the effect of the injected material was not observed for either male or female rats in the test group (2,000mg/kg). Conclusions : The contents of aconitine in Aconiti Radix lateralis preparata was lower for decoction of Sambutang-P with ginseng radix alba than for decoction of only Aconiti Radix lateralis preparata. This suggests that ginseng radix alba can dilute toxicity of Aconiti Radix lateralis preparata. As for a single oral toxicity test of Sambutang-P that contains Aconiti Radix lateralis preparata, no abnormal reaction was observed even when the injection amount far exceeded a toxic dose or a lethal dose. Thus, it is deemed that using Sambutang-P at a clinically prescribed dose would not lead to hepatoxicity.

Aim: Although preoperative chemoradiatherapy (CRT) has proven its benefits in terms of decreased toxicity, there is still a considerable amount of cases that do not receive postoperative CRT. Oncologists at different geographic locations still need to know the long-term effects of this treatment in order to manage patients successfully. The current paper reports on long-term quality of life (QOL) and late side effects after adjuvant CRT in rectal cancer patients from 5 centers in Anatolia. Methods: Rectal cancer patients treated with postoperative CRT with minimum 1-year follow-up and were in complete remission, were evaluated according to RTOG and LENT-SOMA scales. They were also asked to complete Turkish version of EORTC QLQ-C30 questionnaire and the CR-38 module. Each center participated with the required clinical data. Results: Two hundred and thirty patients with median age of 55 years participated and completed the study. Median follow-up time was 5 years. All patients received RT concomitant with chemotherapy. Common parameters that both increased functional health scales and yielded better symptom scores were long term interval after treatment and sphincter-saving surgery. In addition, surgery type and follow-up time were determined to be predictors of QOL scores and late toxicity grade. Conclusion: Postoperative CRT was found to have a great impact on the long term QOL and side effects in rectal cancer survivors. The factors that adversely affect these are abdominoperineal resection and shorter interval. The findings may encourage life-long follow-up and cooperation with patients, which should be mentioned during the initial counseling.

암하에서 3일간 발아시킨 해바라기 유식물의 유근을 절단한 후 붕소 첨가구와 비첨가구에서 온도와 pH 처리에 의한 부정근 발생을 조사하였다. 붕소 미첨가구에서는 부정근이 발생하지 않았으나, 붕소 첨가구에서는 배축의 하위부에서 부정근 발생이 유도되었다. 낮은 pH 처리에 의해 부정근이 손상되었으나 $Ca^{2+}$을 함께 처리한 붕소 첨가구에서는 현저하게 회복되었는데, 이것은 proton 독성을 극복하는데 calcium이 필요하며 proton 독성이 뿌리에서 중요한 기능을 하는 펙틴 다당류의 안정성을 방해하는 현상과 관련이 있음을 시사해준다. 부정근 생장에 최적온도는 $25^{\circ}C$이었다. 붕소 결핍의 가장 뚜렷한 현상은 부정근 생장의 정지이었으나 붕소 첨가구에서 부정근 생장은 향상되었다. 붕소 비첨가구에 ascorbate를 처리하였을 때 부정근의 생장은 촉진되었다. 이러한 사실들로 보아 붕소 결핍, 낮은 pH 및 온도저해로부터 야기된 부정근 생장의 억제는 ascorbate대사가 교란된 결과에 기인되는 것으로 사료된다.

본 연구는 배지 구성물질로서 발포 유리질 소재(CGF)와 탄화 밤나무 목재입자(CCW)를 이용하여 배지를 재발하고 원예재배용 배지의 국산화를 위해 수행되었다. 토마토 종자는 발포 유리질 소재, 탄화 목재입자, 입상암면(GR), 그리고 피트모스를 혼합한 4종의 배지를 만들어 플러그 트레이에 충진하여 종자를 200구 플러그 트레이에 4반복으로 파종한 후 fog 번식상에서 3일간 발아시켰다. 발아 후 양지붕형 유리온실에 난괴법으로 배치하여 저면관수로 양액을 공급하여 육묘하였다. 상업적으로 이용되는 공정육묘 배지(토실이)를 대조구로 이용하였다. 플러그묘의 생육은 파종 후 31일째 측정하였다. 모든 처리에서 유사한 생육결과를 나타냈지만 특히 CCW(67%)+peatmoss(33%) 혼합배지에서 초장, 뿌리등급, 생체중, 그리고 배지의 기상과 가비중이 다른 처리에서보다 유의성 있게 좋았다. 모든 배지의 pH는 6.3∼7.4의 범위로 측정되었다. CGF와 입상암면의 혼합비율이 증가할수록 배지의 pH는 증가하였다. 재배 후 배지의 EC는 대조구에서 가장 높았으나 독성증상은 관찰되지 않았다. 엽수와 엽록소 함량은 처리간 유의성이 없었다.
