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 acute toxicity of orally administered poly(sodium acrylic acid-acrylic acid), powerfully water-absorbent polymer, was el'aluated in Sprague-Dawley rats and feR mice. Rats and mice aging 6 weeks were gavaged with 0, 2.0, 3.0, 4.4, 6.7, or 10 g of poly(sodium acrylic acidacrylic acid)/kg in com oil. No animal died by treatment and any toxic symptom was not observed in the treated animals during 2 weeks. The body weight of the treated animals was not significantly different from the controls. The results of macroscopic examination on the organs of the treated animals revealed no abnormal findings. Therefore, it was concluded that poly(sodium acrylic acidacrylic acid) was practically non-toxic when it was orally administrated to rats and mice up to 10 g/kg, and its $LD_{50}$ was evaluated more than 10 g/kg in rats and mice.

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.

The present study was carried out to investigate the potential toxicity of highly-developed rice varieties, Oryza sativa cvs. Jukjinjubyeo, Heuginjubyeo and Heughyangbyeo by a single oral dose in ICR mice. The test article was orally administered once by gavage at dose levels of 0, 2.5, 5.0, and 10.0 g/kg body weight (n=10 for male and female mice for each dose). We examined the number of deaths, general clinical signs, body weights and biochemical analysis for sexes and doses of mice between control and experimental groups. As a result all of the groups were alive during experimental periods and none of the significant clinical symptom and body weight changes were shown in all of the groups. Plasma glucose levels were valued for both control and experimental groups and there were no significant differences between the groups. The activities of aminotransferase were not increased in all experimental groups compared to control groups. The results suggest that the toxicity of the aleurone layer of Oryza sativa cvs. Jukjinjubyeo, Heugjinjubyeo and Heughyangbyeo are low and its $LD_{50}$ is over 10.0 g/kg body weight in both male and female mice.

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.

Three-day-old sunfower(Helianthus annuus L.) seedlings were do-rooted and incubated in the nutrient solutions that contained either deficient or sufficient boron supply, and exposure to various pH and temperatures. In the absence of boron, no adventitious roots were formed in the majority of the seedlings. Boron caused the development of numerous adventitious roots in the lower part of the hypocotyl. The low pH damage was ameliorated by the simultaneous application of calcium, implying the involvement of calcium-requiring process in overcoming proton toxicity. Borate showed a strong ameliorative effect with $Ca^{2+}$. These results suggest that the primary target of proton toxicity may be linked to a disturbance of the stability in the pectic polysaccharide network, where calcium plays a key role in plant roots. Maximum temperature for the growth of adventitious roots was $25^{\circ}C$. Although cessation of growth is the most apparent symptom of boron deficiency, exogenous ascorbate improved adventitious root growth in plants in the absence of boron. From the results it is suggested that the inhibition of adventitious root resulting from boron deficiency, low pH and temperature damage may be a consequence of disrupted ascorbate metabolism.

This study was conducted in a commercial plug glasshouse in Sacheon to examine the possibility of producing tomato plug seedlings using various growing media containing cellular glass foam (CGF)and carbonized chestnut woodchips (CCW) as medium components. Plug seedlings of 'Seogun' tomato were grown in media containing 50% CCW＋50% peatmoss, 33% CGF＋67% peatmoss, and 50% peatmoss＋50% granular rockwool. A commercial plug medium (Tosilee) was used as the control. All seeds were sown in 200 cell plug trays on November 28, 2001. Seedling growth was measured at 31 days after sowing. Each treatment showed a similar growth result as compared to the control. Plant height, root grade, fresh weight, and air space and bulk density of the medium were significantly greater in the 33% CGF＋67% peatmoss treatment than those in the other media. However, growth was slightly suppressed in the 50% CCW＋50% peatmoss. pH and EC of the media were the highest in the control treatment, although no toxicity symptoms had been observed. The results suggest that perlite can be replaced with a new material such as CGF in the commercial scale production of plug seedlings of 'Seogun' tomato.
