Serum concentration of selenium were measured ; Studying 36 patients with Hepatoma. 19 with Hepatitis 15 with Liver cirrhosis and 67 Normal control to discover the correlation between serum selenum and cancer. And it have tested also the serum protein and albumin to compare the nutrition status by researching the same persons above The results of those two experiments are as follow : 1) The mean of each group of patients resulting from mearsuing the serum protein content showing 6.91$\pm$0.10g/dl in the patients with hepatoma 7.05$\pm$0.17g/dl in the ones with hepatitis 6.42$\pm$0.13g/dl in the ones with liver cirrhosis and 7.46$\pm$0.06g/dl in the normal control is all being within the normal range such as 6.0-0.8(g/dl) while the distribution is revealin 10.5%, 13.3% in the patients with hepatitis and liver cirrhosis which are below the normal range and 47.2%, 96.9%, 80.0% in the low range of normal one ; therefore in could see that patientsw compared with normal control are in low level in the serum protein content 2) The mean based on the consquence of serum albumin measurement is 3.74$\pm$0.11g/dl. 4.26$\pm$0.13g/dl 4.73$\pm$0.06g/dl in the patients with hepatoma hepatits and normal control which are in between the normal range such as 3.5-5.5(g/dl) except the patients with liver cirrhosis(3/05$\pm$0.12g/dl) while the distribution of the patients with hepatoma an liver cirrhosis is showing 27.8% 73.3% which are below the normal one and 55.5%, 52.6% and 26.7% in the patients with hepatoma hepatits and liver cirrhosis which are in the low area of normal range ; as a result It could find that patients. compared with the normal control are in low level in serum albumin measurement. 3) The mean consulting the serum concentration is 430.86$\pm$26.06$\mu\textrm{g}$/1, 192.37$\pm$18.15$\mu\textrm{g}$/1 186.73$\pm$23.99$\mu\textrm{g}$/1, 196.94$\pm$8.94$\mu\textrm{g}$/1 in the patients with hepatoma hepatitis liver cirrhosis and noramal control ; it shows 2.19 times increasing of serum selenium concentra-tion in the patients with hepatoma 'compared with the normal control and patients with hepatoma spread out at a still higher range in serum selenium concentration test. 4) The serum selenium concentration is not quite dependent on sexes and doesn't show any correlation with age, serum protein, serum albumin. The nutrition status of patients, rested on the results of those experiments, stays in low level, which is caused by that they are in low stage of serum protein and serum albu¬min. In serum selenium concentration, patients with hepatitis and liver cirrhosis, specially, show the condition as good as normal control's; while patients with hepatoma are indicating a significant increasing compared with the three groups, which can be reasoned into that there is a possibility for the patients to take selenium and chemotherapy or radiation treatment, and have high serum selenium concentration by poor excreting of seleno methionine, which is caused by low serum protein content And another thing can be reasoned is that the difference in origination mechanism hetween korean and western people. As a result, It showed that the correlation between serum selenium and seses, age, serum protein, and serum albumin neither exists nor affects on each other.

A 12-year-old male American Cocker Spaniel was diagnosed with a type of chronic hepatits (CH) called cholangioheaptits. Routine supportive medication was administered to the patient, and ex vivo boosted immune cell (EBI-C) therapy was used for the treatment. A histopathologic examination of the liver 19 months later revealed that the cholangiohepatitis had progressed to cholangiocarcinoma. The medication and immune cell therapy was maintained. Two months after the new diagnosis, the patient's state worsened, and the dog died 635 days after the first visit. EBI-C therapy is a type of immunotherapy, where immune cells are isolated from the patient's peripheral blood mononuclear cells, expanded ex vivo, and then infused into the patient intravenously every two weeks. EBI-Cs (mean: 2.78 × 10⁸ cells) were obtained 38 times and infused every two weeks. Most EBI-C were T-lymphocytes (99.24% of total EBI cells). T-lymphocytes produce large interferon (IFN)-γ, and IFN-γ inhibits liver fibrosis in dogs with CH. Moreover, in bile duct cancer, an increase in T-lymphocytes correlates with decreasing tumor invasion and metastasis. Thus, we propose that EBI-C therapy is applicable as a new supportive therapy for canine liver disease if other treatments like drug medication, surgery, or radiation are unavailable.

Objective : We have currently changed treatment strategies to methotrexate(MTX)-based preirradiation chemotherapy with subsequent planned radiation for the initial therapy of primary central nervous system lymphoma (PCNSL). The aim of this study was to evaluate the results of treating PCNSL with chemotherapy plus radiotherapy (CRT) or radiotherapy(RT) alone. Method and Material : This study involved 10 females and 3 males patients with a mean age of 54.2 years. All patients underwent surgery, open(8 cases) or stereotactic biopsy(5 cases) for histological diagnosis. Eleven tumors were diffuse large B-cell lymphomas. Tumor volume change in the follow-up images and survival time were evaluated in patients treated with CRT and RT alone. In the beginning, two patients received ProMACE-Cytabom chemotherapeutic regimen, but did not complete the course and died of progressive tumor 8 and 9 months after diagnosis, respectively. One patient died at 6 months before chemotherapy. These three were excluded from the survival analysis. Five patients(RT group) completed full courses of cranial irradiation with or without boost. For the current combined modality treatment, high-dose MTXbased chemotherapy(systemic and intrathecal MTX, IV vincristine, and oral procarbazine) followed by whole brain irrdiation to 45Gy to tumor was introduced in 5 patients of CRT group. Result : A complete response was achieved in three of five who received RT only and in all of five who received CRT. All patients in CRT groups are in disease free status at a mean 23 months following therapy. The RT group patients refused any additional salvage therapy at tumor relapse and survived at mean 20 months from diagnosis. The Karnofsky performance status improved in eight of ten patients with treatment. The treatment toxicity included leukoencephalopathy in RT group and severe leukopenia, transient hepatitis, avascular necrosis of femoral head, hearing loss, and amenorrhea in CRT group, respectively. Conclusion : The combined modality therapy of MTX-based chemotherapy plus radiotherapy for PCNSL may enhance tumor response and improve patient survival. The patients who received CRT should be carefully followed up because of the higher risk of treatment-induced late neurotoxicity.

Human skin is the first line of defense for the protection of the internal organs of the body from different stimuli. Ultraviolet B (UVB) irradiation induces skin damage and inflammation through the secretion of various cytokines, which are immune regulators produced by cells. To prevent the initiation of skin inflammation, keratinocytes that have been irreversibly damaged by radiation must be removed through the apoptotic mechanism. Ixeris dentata (family: Asteraceae) is a perennial medicinal herb indigenous to Korea. It has been used in Korea, China, and Japan to treat in digestion, pneumonia, diabetes, hepatitis, and tumors. To gain insight into the anti-inflammatory effects of I. dentata, we examined its influence on UVB-induced pro-inflammatory cytokine production in human keratinocytes (HaCaT cells), by observing cells that were stimulated with UVB in the presence or absence of I. dentata. In the present study, pro-inflammatory cytokine production was determined by performing enzyme-linked immunosorbent assay, reverse transcription polymerase chain reaction, and western blot analysis to measure the activation of mitogen-activated protein kinase (MAPKs). I. dentata inhibited UVBinduced production of the pro-inflammatory cytokine interleukin (IL)-6 in a dose-dependent manner. Further, I. dentata inhibited the UVB-induced expression of cyclooxygenase (COX)-2. Furthermore, I. dentata inhibited the phosphorylation of c-Jun NH2-terminal kinase and p38 MAPKs, suggesting that it inhibits the secretion of the pro-inflammatory cytokines IL-6 and IL-8, and COX-2 expression, by blocking MAPK phosphorylation. These results suggest that I. dentate can potentially protect against UVB-induced skin inflammation.
