In recent years, national health insurance(NHI) coverage had been expanded gradually for cancer as a severe disease requiring high level of medical expenditure, to reduce patient's financial burden. But, subjective burdens level for out-of-pocket(OOP) money expense are still considerable owing to high medical cost and decent numbers of services not covered by benefit plan. This study aimed to investigate OOP medical expenditures and identify factors influencing subjective financial burden in cancer patients. A 28-items questionnaire for self-reporting by responders was designed to satisfy study goal and finalized following by one pilot study and experts' verification process. Subjects were enrolled during July to October 2010 through regular meetings organized by five patient or patient-advocacy groups had acknowledged the study purpose. Subjects who aged 20 or more, have histories of cancer diagnosis and anticancer drug use, and voluntarily agreed to participate in this study were recruited. Total 107 subjects included in the analysis have cancer lesions in breast, colon, kidney, liver or stomach at the stages from I to IV. Approximately 73% of them has passed less than 5 years since cancer diagnosis. For the OOP medical expenditure regarding cancer, less 6 million won was in 31%, 6-15 million won in 35% and more than 15 million won in 28% of responders, and more than half responders(58%) felt financial burden subjectively. 63% of responders had subscribed commercial insurances, resulting in money receipts of more than 10 million won since cancer diagnoses in 76% of responders. Logistic regression results showed significant differences in subjective OOP financial burden level depending on gender, household income level, benefit type, commercial insurance money receipt degree, year cancer diagnosed, cancer lesion, therapy type, duration of anticancer drug use, drug listing in national formulary, total OOP medical expenditure and total OOP anticancer drug expense. They had mixed feelings both wishes to expand NHI coverage to reduce financial burden(70%) and no willingness to increase premium(59%). This result suggested that NHI might direct future strategies to reduce absolute total OOP medical cost and expand benefit plan coverage in higher burden groups in particular.

Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sex-specific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions: Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.
Background: Embryonic stem cells (ESCs) have the potential to form teratomas when implanted into immunodeficient mice, but data in immunocompetent mice are limited. We therefore investigated teratoma formation after implantation of three different mouse ESC (mESC) lines into immunocompetent mice. Materials and Methods: BALB/c mice were injected with three highly germline competent mESCs (129Sv, BALB/c and C57BL/6) subcutaneously or under the kidney capsule. After 4 weeks, mice were euthanized and examined histologically for teratoma development. The incidence, size and composition of teratomas were compared using Pearson Chi-square, t-test for dependent variables, one-way analysis of variance and the nonparametric Kruskal-Wallis analysis of variance and median test. Results: Teratomas developed from all three cell lines. The incidence of formation was significantly higher under the kidney capsule compared to subcutaneous site and occurred in both allogeneic and syngeneic mice. Overall, the size of teratoma was largest with the 129Sv cell line and under the kidney capsule. Diverse embryonic stem cell-derived tissues, belonging to the three embryonic germ layers, were encountered, reflecting the pluripotency of embryonic stem cells. Most commonly represented tissues were nervous tissue, keratinizing stratified squamous epithelium (ectoderm), smooth muscle, striated muscle, cartilage, bone (mesoderm), and glandular tissue in the form of gut- and respiratory-like epithelia (endoderm). Conclusions: ESCs can form teratomas in immunocompetent mice and, therefore, removal of undifferentiated ESC is a pre-requisite for a safe use of ESC in cell-based therapies. In addition the genetic relationship of the origin of the cell lines to the ability to transplant plays a major role.
Cyclophosphamide (CP) is widely used in cancer and lymphoma treatments and as an immunosuppressant drug. CP is a DNA alkylating agent that metabolizes into 4-hydrocyclophosphamide (4H-CYP) and aldophosphamide in hepatocytes. However, its metabolites cause DNA synthesis disorder, leading to apoptosis and toxic side effects. The development of technology to minimize this side effect is essential to improve CP's clinical application. Various bioactive compounds have been reported to have anti-cancer and antioxidant functions and preventive or therapeutic roles in metabolic diseases. Many researchers have attempted to minimize the side effects and improve the efficacy of these drugs together with the use of bioactive compounds. Ulmus macrocarpa Hance has been used for the treatment of edema, mastitis, stomach pain, tumors, cystitis, and other inflammatory diseases. The aim of this study was to investigate at the histological level the protective function of U. macrocarpa Hance against CP's side effects and any potential toxic effect of U. macrocarpa Hance in the liver and kidney. Water extracts of U. macrocarpa Hance reduced CP-induced toxicity and did not induce any histological damage in the liver and kidney. Therefore, U. macrocarpa Hance would be applicable in the pharmaceutical industry.
To study the differentiating cytomorphological features of Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) using fine needle aspiration cytology (FNAC), cytomorphological features of 16 patients with HL (n=8) or ALCL (n=8) were analyzed. In the initial cytological diagnosis prior to biopsy, HLs were properly diagnosed in 4 out of 8 cases (4 HL, 2 atypical, 2 benign), whereas all ALCL were diagnosed as malignancies. However, correct diagnosis of non-Hodgkin lymphoma (NHL) was made in only two ALCL patients (2 NHL, 1 HL, 1 sarcoma, 4 malignancy without specific type). Overall, the percentage of large abnormal cells ranged from 30% to 90% in ALCL except for one case, whereas it was less than 5% in all 8 HL. A spectrum of atypical cells was more characteristic of ALCL. In contrast, HL showed an sharp difference between reactive lymphoid cells and neoplastic ones (bimorphic pattern). Moreover, the emergence of kidney-shaped abnormal cells or wreath-like multinucleated cells was helpful in diagnosing ALCL. The combination of thesefeatures would be useful in differentiating HL and ALCL. Nevertheless, these two types of lymphomas cannot be definitely distinguished based on cytomorphological features alone. Therefore, the aim of FNAC would be to suggest a specific diagnosis and indicate the need for a biopsy.
Clinical studies were carried out 83 cases of patients with colorectal cancer treated by Hangamdan(抗癌丹) from January 1th 1998 to September 30th 2000. The results were summarized as follows; 1. Distribution of those attached by colorectal cancer, by sex, showed that Male is more then Female, by age, showed that the number of fifties is majority. 2. Distribution of diagnostic stage, in descending order; stage III(53%, top), stage IV(45.8%). 3. The effects of maintenance and improvement in the symptoms with traditional oriental therapy(83.3%) and combined treatment of western and oriental therapy(92.1%) were observed. The effects of the symptoms were as follows: diarrhea(37.3%), abdominal pain (25.3%), general body weakness(22.9%), nausea(20.5%) and etc. in orders. 4. Analysis of hematology attached by colorectal cancer, maintenance and increasing of WBC(89.9%), RBC(74.7%), Hgb(81.1%), Platelet(92.4%) were observed. After taken Hangamdan, the safety of the liver and kidney were as follows; maintenance and decreasing of AST(85.9%), ALT(94.8%), GTP(87.5%), Creatinine(90.9%) were observed. 5. of IL-12 and $IFN-\gammer$ attached by colorectal cancer, increasing of IL-12(53.3%), IFN-{\gammer}(80%)$) were observed. 6. Analysis of QOL attached by colorectal cancer, maintenance and improvement of combined treatment of western and oriental therapy(89.6%), traditional oriental therapy(83.3%) were observed. 7. Analysis of survival in patients with IV stage of colorectal cancer, above 7 months(18.4%), 12 months(65.8%). 8. Analysis of antitumor effects, maintenance of traditional oriental therapy(83.3%) and maintenance and improvement of combined treatment of western and oriental therapy(80.5%) were observed. Analysis of tumor marker attached by colorectal cancer, maintenance and decreasing of CEA(78.8%) were observed. 9. Analysis of curative valuation, maintenance and improvement of traditional oriental therapy(83.3%), combined treatment of western and oriental therapy(72.7%) were observed. From the above results, it is suggested that Hangamdan has significant effects of antitumor and immune activity, also could be usefully applied for colorectal cancer patients by combination with western therapy or alone.
L-3-[$^{123}I$]iodo-${\alpha}$-methyltyrosine([$^{123}I$] IMT) was synthesized by electrophilic radio-iodination using chloramine-T and Iodobead in phosphate buffered solution. And the biodistribution was examined in 9L glioma bearing rats. The radiosynthesis of [$^{123}I$]IMT with iodobead was simpler and higher in radiochemical yield(88%) than the method using chloramine-T(83%) as radioiodinating reagent. The highest yield was obtained from the reaction using 1 piece of Iodobead, $200{\mu}g$${\alpha}$-methyltyrosine in $100{\mu}l$ phosphate-buffered solution(pH 5.5) and the reaction was completed in 7min. 24 hours after the injection, the biodistribution in 9L glioma transplanted rats revealed the in vivo deiodination, the excretion via kidney, and 3 times higher uptake in the tumor than normal brain. These results suggest the promising clinical use of [$^{123}I$] IMT in the various malignancies.

In this study, Banhasasim-tang extracts (BSTE) have an inhibitory effects on cisplatin-induced nephrotoxicity in mouse model. Cisplatin is the most widely used anticancer drug for treatment of various cancer. However, cisplatin treatment to cancer patients leads to many side effects such as nephrotoxicity and body weight decrease. We hypothesize that BSTE improve the cisplatin-induced side effects in mouse model. We found that BSTE administration protected tubular injury by cisplatin in mouse model. BSTE also inhibited increase of creatinine and BUN induced by cisplatin injection in serum. Collectively, our data suggest that BSTE could be a therapeutic agent for reducing kidney injury induced by cisplatin treatment in cancer patients.

Background: Valproic acid (VPA) is a potent anticancer and antiangiogenic agent. However, design and synthesis of chemical derivatives with improved antiangiogenic and anticancer activities are still necessary. In this study a library of novel derivatives of VPA was synthesized and tested. Methods: A human liver cancer cell line (HepG2) and a human normal embryonic kidney cell line (HEK 293) were exposed to various concentrations of VPA derivatives for 24 hours and cell viability was checked by MTT colorimetric assay. Anti-angiogenic properties were evaluated in transgenic zebrafish embryos. Results: N-valproylglycine derivatives suppressed survival almost 70% (p value 0.001) in HepG2 cells but only 10-12% in HEK 293 cells (p value 0.133). They also suppressed angiogenic blood vessel formation by 80% when used between $2-20{\mu}M$ in zebrafish embryos. Valproic acid hydrazides showed moderate level of anticancer activity by affecting 30-50% (p value 0.001) of cell viability in HepG2 cells and 8-10% in HEK293 cells (p value 0.034). Conclusion: The majority of compounds in this study showed potent and stronger antiangiogenic and anticancer activity than VPA. They proved selectively toxic to cancer cells and safer for normal cells. Moreover, these compounds inhibited developmental angiogenesis in zebrafish embryos. Based on the fact that liver is a highly vascularized organ, in case of liver carcinoma these compounds have the potential to target the pathological angiogenesis and could be an effective strategy to treat hepatocellular carcinoma.
Medical Internal Radiation Dose(MIRD) schema was developed for calculating the absorbed dose from the administered radiopharmaceuticals. With the biological distribution data and the physical properties of the radionuclide we can estimate the absorbed dose by the MIRD schema. For the thyroid cancer patients received $^{131}I$ therapy, the absorbed dose to the bone marrow is the limiting factor to the administered dose, and the duration of admission is deter-mined by the retained activity in the whole body. To monitor the whole body radioactivity, we used Eberline Smart 200 system using ionization chamber as a detector. With the time activity curve of the whole body, total body residence time was obtained. From the ICRP publication 53, the residence times of the source organs, such as kidney, urinary bladder content and stomach, were used to calculate the absorbed doses of the target organs, such as stomach, red marrow, bladder wall and remaineder total body. In 8 thyroid cancer patients with 175 mci of $^{131}I$ administered orally, the mean absorbed dose in the bladder wall was 375.1, in the stomach 285.1, red marrow 25.4 and total body 22.4 rad respectively. For the monitoring of the large administered activity, this method seemed to be quite useful.
