The effect of Banhasasim-tang extracts on the cardiac toxicity and general symptom induced by Doxorubicin administration(Three injection protocol) were monitored using male ICR mice. The changes of body weight, clinical signs, necropsy findings and organ weights of heart were observed. The results were as followed. 1. Decrease of body weight after Doxorubicin treatment were dose-dependently inhibited by Banhasasim-tang extracts. 2. The degrees of anorexia, ataxia and dehydration that were observed in Doxorubicin treatment group were dose-dependently inhibited by Banhasasim-tang extracts. 3. Increase of absolute and relative heart weight observed in Doxorubicin treatment group were dose-dependently inhibited by Banhasasim-tang extracts. In addition. the degrees of heart congestion and enlargement were significantly and dose-dependently decreased after Banhasasim-tang extracts dosing groups compared to that of Doxorubicin treatment group. In conclusion, the toxicity of Doxorubicin treatment(decrease of body weights, clinical signs such as anorexia, ataxia and dehydration, changes of organ weights of heart) was inhibited and/or prevented by Banhasasim-tang extracts. According to these results. it is considered that Banhasasim-tang has some preventive effect against to toxicity induced by Doxorubicin.

산성화된 토양에서 생육하는 오이가 황백화 되면서 시드는 증상이 발생하여 현장에서 토양을 검사하여 진단하고 현장에서 토양 pH를 측정한 결과 4.2로 매우 낮은 강산성이었고, 실험실에서 분석한 결과 4.5로 나타났다. 토양을 풍건하여 토양 pH를 측정한 결과 4.5로 강산성이었다. 그래서 토양을 포화추출법으로 용액을 채취하여 분석한 결과 Al이 해리되어 나오고 있었고 식물체를 분석한 결과 Al이 고농도로 흡수되어 있었으며 질소와 Ca의 함량이 매우 낮았다. 현장에서 pH를 교정하기 위하여 소석회 포화액과 탄산칼슘을 처리한 결과 pH를 6.5로 조절할 수 있는 소석회 450 mL $plant^{-1}$를 처리한 주에서 어린 잎부터 정상적인 생육을 하였다. 이 결과로부터 강한 산성토양에서 나타난 오이의 황백화 증상은 Al이 해리되어 식물체로 과잉 흡수되고 이로 인하여 질소와 칼슘의 부족으로 야기된 것으로 나타났다.

Kami-honghwa-tang(KH-19) is a prescription for reducing the side effect of radiotherapy. In this study, safety of KH-19 was evaluated by GLP guideline of Korea Food and Drug Administration. In acute oral toxicity study on rat, transient inhibition of weight increase was shown, but change in general symptom was not detected. No dead animal was observed up to 5,000 mg/kg in both male and female animals. In acute oral toxicity study on Beagle dog, transient vomiting, diarrhea, anorexia, and weight reduction was observed. However, no dead animal was observed up to 2,000 mg/kg in both male and female animals.

Purpose: This study aimed to develop and test a structural model for chemotherapy-related cognitive impairment of breast cancer patients based on a literature review and Hess and Insel's chemotherapy-related cognitive change model. Methods: The Participants consisted of 250 patients who were ${\geq}19$ years of age. The assessment tools included the Menopause Rating Scale, Symptom Experience Scale, Hospital Anxiety and Depression Scale, Everyday Cognition, and Functional Assessment of Cancer Therapy-Breast Cancer. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs. Results: The modified model was a good fit for the data. The model fit indices were ${\chi}^2=423.18$ (p<.001), ${\chi}^2/df=3.38$, CFI=.91, NFI=.91, TLI=.89, SRMR=.05, RMSEA=.09, and AIC=515.18. Chemotherapy-related cognitive impairment was directly influenced by menopausal symptoms (${\beta}=.38$, p=.002), depression and anxiety (${\beta}=.25$, p=.002), and symptom experiences (${\beta}=.19$, p=.012). These predictors explained 47.7% of the variance in chemotherapy-related cognitive impairment. Depression and anxiety mediated the relations among menopausal symptoms, symptom experiences, and with chemotherapy related cognitive impairment. Depression and anxiety (${\beta}=-.51$, p=.001), symptom experiences (${\beta}=-.27$, p=.001), menopausal symptoms (${\beta}=-.22$, p=.008), and chemotherapy-related cognitive impairment (${\beta}=-.15$, p=.024) had direct effects on the quality of life and these variables explained 91.3%. Conclusion: These results suggest that chemotherapy-related toxicity is highly associated with cognitive decline and quality of life in women with breast cancer. Depression and anxiety increased vulnerability to cognitive impairment after chemotherapy. Nursing intervention is needed to relieve chemotherapy-related toxicity and psychological factor as well as cognitive decline for quality of life in patients undergoing chemotherapy.

수도에 대한 비소의 피해 및 아연-비소간의 교호작용을 온실실험으로 조사하였다. 비소 피해의 증세는 수도를 시들게 하는 것이었으며 지상부 및 지하부의 생장을 감소시키었다. 비소 피해는 1 ppm의 비소 처리구에서도 관찰되었다. 아연의 시용은 수도의 비소흡수를 억제하지는 못했지만 비소 피해를 완화시키었다. 반면 처리된 비소는 아연의 흡수를 감소시키었으며, 따라서 아연시용의 효과는 비소피해에 의한 아연흡수 감소를 보상하였기 때문이다. 이 시험중 공시토양인 Crowley SiL의 비교적 높은 토양반응에 기인하여 철 결핍증이 관찰되었다.

Ammonium nitrogen is volatilized as ammonia at high pH soil. This study was conducted to observe an injury cause of egg plant grown in a high pH rockwool amended with ammonium phosphate. The etiolation symptom (yellowing) was appeared on veins of a leaf but not in healthy root when nutrient solution containing ammonium phosphate in addition to essential elements was applied in a top soil of which pH was 7.8. However, the same symptom did not appeared in the egg plant from the top soil in which the nutrition solution containing potassium phosphate instead of ammonium phosphate was applied. pHs were similar between these two different solutions. This revealed that the injury was caused by ammonia gas.

The acute toxicity of orally administered Yan-Sheng health liquid (YSHL), water extracts from twelve Chinese drugs (Cervi Cornu, Lonicerae Flos, Foeniculi Fructus, Glycyrrhizae Radix, Liriopis Tuber, Raphani Semen, Bombyx, Ginseng Radix alba, Cinnamomi loureirii Cortex, Epimedii Herba, Zingiberis Rhizoma, Lycii Fructus) was evaluated in male and female Sprague-Dawley rats and ICR mice. Rats and mice aging 5 weeks were gavaged with 0, 2.0, 3.0, 4.4, 6.7, 10.0, 66.7, or 100.0 ml/kg of YSHL. No animal died by oral treatment and no toxic symptom was observed in the treated animals during 5 days. 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 YSHL was practically non-toxic when it was orally administered to rats and mice, and its LD50 was suspected to be greater than 100 ml/kg in rats and mice.

Subacute toxicity of Hantabax, epidemic hemorrhagic fever vaccine, was investigated in ICR mice with subcutaneous injection. Any significant toxic symptom was not observed in the treated mice during the experimental period. Macroscopic examination on the organs of tested animals showed no abnormal findings. On autopsy, no significant changes were found in all organs examined.

Objective: The study was designed to assess the skin and subcutaneous toxicity in patients with advanced colorectal carcinoma treated with four different schedules of FOLFOX. Methods: The patients with histologically confirmed advanced colorectal carcinoma (CRC) were included in the study as per specified inclusion criteria. Toxicity was graded according to CTC v2.0. The frequency of grade 3 and 4 adverse effects were comparatively assessed in each treatment arm. Results: Very severe toxicity was attributed to the FOLFOX7 schedule. The difference between the incidence rate of grade 4 toxicity with all other grades for all parameters of skin and subcutaneous toxicity was highly significant (p=0.00<0.001). Grade 4 hand and foot syndrome was reported only in the FOLFOX7 treatment arm. The most frequent adverse symptom of skin and subcutaneous toxicity reported in the patients treated with modified schedule of FOLFOX was pruritus (grade 1). Frequency and onset of skin and subcutaneous toxic symptoms like alopecia (p=0.000), nail discoloration (p=0.021) and pruritis (p=0.000) was significantly different in each FOLFOX treatment arm. A few cases of oncholysis were also reported in the FOLFOX7 treatment arm. Hand and foot syndrome was fast progressing in patients with grade 1 toxicity. Conclusion: Higher frequency and severity of hand and foot syndrome and pruritus wasa found in the FOLFOX7 treatment arm. Skin and subcutaneous toxicity was comparatively low in the FOLFOX6 treatment arm.
