Purpose : It is very important to endow the cancer patients underwent chemotherapy with satisfactory quality of life (QOL). However, little is known about the factors influencing QOL during chemotherapy. Therefore, we designed this study to find out the factors influencing QOL in the cancer patients who underwent chemotherapy. Methods : Ninety-seven cancer patients were studied, prospectively. The patients' characteristics were as follows; median age(range): 48(19{\sim}83) years, male:female; 57:40, PS:0,1/2,3;55/42 patients, diagnosis(number): lymphoma (28), lung cancer (22), gastrointestinal cancer (18), sarcoma (12), breast cancer (12), gynecological cancer (5), Stage: I,II/III.IV;37/60 patients. We used EORTC QLQ-C30 questionnaires to evaluate QOL. EORTC QLQ-C30 scores were performed before the onset of chemotherapy and after the end of 3 cycles of chemotherapy. The correlation of these scores with performance status (PS), diagnosis, disease stage, response to chemotherapy, and regimen related toxicity was evaluated. Results : The responder group (CR, PR) demonstrated marked improvement of social functional and emotional scales to non-responder group (SD,PD) (P=0.024, 0.045). Non-hematologic regimen related toxicity such as mucositis, nausea and vomiting was significantly correlated with pain scale change (P=0.043). Other factors had no notable correlation with QOL changes. Conclusion : Our preliminary study results may suggest as follows. The response to chemotherapy is associated with the change of social functional and emotional scales and the severity of non-hematologic regimen related toxicity is associated with pain scale change.

Purpose: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. Materials and Methods: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. Results: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. Conclusion: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

Objectives: We report a case of traditional Korean medicine (TKM) treatment for skin side effects after taking afatinib (Giotrif$^{(R)}$). Methods: A 62-year-old female who was diagnosed with non-small cell lung cancer stage 4 (T4N2M1b) and was on treatment with afatinib (29.56 mg/day for 4 months) complained of skin toxicity as a side effect. For 16 admission days, the patient was treated with acupuncture, moxibustion, and herbal medicine (oral decoction and external ointment). Results: Improvement of skin toxicity was measured by a numeric rating scale. In addition, Quality of life (QOL) was measured using EORTC Quality of Life Questionnaire, Core 30 (EORTC QLQ-C30) and EORTC Quality of Life Questionnaire, 13-item lung cancer-specific module (EORTC QLQ-LC13) Developed by the European Organization for Research and Treatment of Cancer (EORTC). Tumor size and carcinoembryonic antigen (CEA) were also examined during follow up. Conclusions: After a combined TKM treatment, skin toxicity symptoms and quality of life scales were significantly improved with no side effects. The tumor size was not changed on computed tomography during follow-up period. CEA levels were decreased.

In the present study, we examined the chemoprotective effects of different rice bran, which are produced by fermentation or not, on doxorubicin induced rat model, and detected the change of components of rice bran. Rats receiving fermented rice bran of 100 mg/kg by oral plus doxorubicin 10 mg/kg had greater weight gain as +24% than that observed with doxorubicin alone. In case of the treatment of non-fermented rice bran of 100 mg/kg by oral with doxorubicin of 10 mg/kg, fermented rice bran showed a -1.3% decrease in body weight. 100 mg/kg fermented rice bran decreased the incidence to 30%, and non-fermented rice bran decreased the incidence to 50%. In lethality, the rate of death of doxorubicin was 60%. 100 mg/kg fermented rice bran decreased to 10% in death rate and non-fermented rice bran to 30%. In gross gastrointestinal pathology, doxorubicin showed the gross gastrointestinal mucosal pathology in 70% of treated rats, fermented rice bran decreased to 40% and non-fermented rice bran to 50%. In the change of constituent, xylose concentration of fermented rice bran was detected to 59.33 mg/g while its concentration of non-fermented rice bran was 11.12 mg/g.

Gene therapy has emerged as a new concept of therapeutic strategies to treat diseases which do not respond to the conventional therapies. The principle of gene therapy is to Introduce genetic materials into patient cells to produce therapeutic proteins in these cells. Gene therapy is now at the stage where a number of clinical trials have been carried out to patients with gene-deficiency disease or cancer. Genetic materials for gene therapy are generally composed of gene expression system and gene delivery system. For the clinical application of gene therapy in a way which conventional drugs are used, researches have been focused on the design of gene delivery system which can offer high transfection efficiency with minimal toxicity. Currently, viral delivery systems generally provide higher transfection efficiency compared with non-viral delivery systems while non-viral delivery systems are less toxic, less immunogenic and manufacturable in large scale compared with viral systems. Recently, novel strategies towards the design of new non-viral delivery system, combination of viral and non-viral delivery systems and targeted delivery system have been extensively studied. The continued effort in this area will lead us to develop gene medicine as "gene as a drug" in the near future.

Hydroxyapatite(HAp, Ca$\sub$10/(PO$_4$)$\sub$6/(OH)$_2$, is a compound with structural and chemical resemblance bone mineral and of particular importance in the field of biomaterials. In addition to the non-toxicity and high compatibility with hard and soft tissue, HAp exhibits strong affinity to host hard tissues and protein molecules. However, HAP is difficult to shape in the specific forms due to its hardness and brittleness. (omitted)

A series of new metallized direct dyes based on benzidine congeners, 2,2'-dimethyl-5,5'-dipropoxybenzidine and 5,5'-dipropoxybenzidine, were evaluated for mutagenicity in Salmonella typhimurium strains TA98 and TA 100. All of the dyes examined were judged to be non-mutagenic with and without metabolic activation while toxicity was seen in some dyes at high doses. The study also suggested that the standard Salmonella mutagenicity plate-incorporated assay was an excellent method for evaluation of dyes for mutagenicity.

In order to figure out the relationships between structural features and biological activity of the host-specific HC-toxin in maize, structurally related cyclic tetrapeptides, chlamydocin and CYL-2 were isolated, and their biological activities in maize were examined. Biological activities of preparations were determined by root growth inhibition and electrolyte leakage bioassays. Chlamydocin and CYL-2 showed toxicities to maize. However, the toxicities of these compounds were non-specific. Thus, the precise peptide ring structure of HC-toxin apparently does not play an important role in toxicity, while resistance of maize to HC-toxin is based on a precise ring conformation.
