Azathioprine is commonly used as immunosuppressive therapy for various inflammatory diseases including chronic glomerulonephritis. Myelosuppression is a common side effect of azathioprine, resulting in the need for dose reduction. However, severe pancytopenia or alopecia is not often encountered. Here, we report a case of severe myelosuppression, and alopecia totalis that occurred after azathioprine treatment in a patient with IgA nephropathy. A 10-year-old boy with IgA nephropathy was treated with oral deflazacort and later with azathioprine. After 4 weeks, the patient complained of hair loss, and despite a dose reduction in azathioprine, he developed bone marrow suppression and alopecia totalis in two weeks. The blood indices and alopecia of the patient had returned to normal after azathioprine withdrawal and 3 consecutive doses of granulocyte colony-stimulating factor. We suggest that physicians remain vigilant to the side effects of azathioprine. Unusual hair loss after azathioprine treatment might suggest a defect in the metabolism of the drug, warranting the discontinuation of azathioprine to prevent more severe side effects.

This study was performed to determine the toxic effect of DA-3030(granulocyte-colony stimulating factor, G-CSF) in beagle dogs. DA-3030(G-CSF) was injected intravenously at doses of 115 $\mu\textrm{g}$/kg/day, 11.5 $\mu\textrm{g}$/kg/day and 1.15 $\mu\textrm{g}$/kg/day seven days per week for 28 days. After completion of the treatments, the dog were necropsied. The number of dead animal was zero in all groups. No specific clinical sign was found, either. In hematological results, WBC was significantly increased dose-dependently in treated groups. In histopathological findings, megakaryocyte and rubricyte were found in the liver and spleen at the dose of 115 $\mu\textrm{g}$/kg/day. Therefore, we could find the extramedullary hematopoiesis was increased. Megaka yocyte and rubricyte were increased in bone marrow, too. In conclusion, those signs were estimated the pharmacological effect of DA-3030(G-CSF). According to the results, non toxic dose of DA-3030(G-CSF) was higher than 115 $\mu\textrm{g}$/kg/day.

Results : 1. The most important concept of IMS is chronic pain illness that may develop into hypersensitivity of the nerves, i.e., neuropathy. 2. Muscle shortening may be triggered by stress, including emotional, physical, external, and internal factors. 3. Muscle shortening increases mechanical tension on the muscles as well as inducing abrasion of the tissues by stretching ligament, tendon, cartilage, bone, and etc. 4. Pain from neuropathy is normally manifested on musculoskeletal system and spasm or shortening play as the central axis of this pain. 5. Neuropathy often appears at the nerve root level and the most important decisive factor of radiculopathy is muscle shortening. 6. Spondylosis is the most common cause of radiculopathy. 7. The most significant treatment principle of IMS is to relieve muscle shortening and remove stimulating determinant from the vertebrae. 8. Dry needling is quite effective for treating various pain caused by muscle shortening.

Inherited metabolic disease is rare disorders that show symptoms mainly in pediatric age and early treatment is important for preventing complications of the disease. Recent development in molecular and biochemical techniques help clinicians with proper diagnosis of patients, however, many of the disease still remain lack of effective therapeutic strategies. Better understanding on biochemical and molecular basis of pathogenesis of the disease combined with advanced medical care would provide new sight on the disease that can also improve the quality of life and long-term prognosis of patients. Traditionally, there are several modalities in the treatment of metabolic diseases depend on the biochemical basis of the disease such as diet restriction, removing or blocking the production of toxic metabolites, and stimulating residual enzyme activity. The inherited metabolic disease is not familiar for many clinicians because the diagnosis is troublesome, treatment is complicated and prognosis may not as good as expected in other diseases. Recently, new therapeutic regimens have been introduced that can significantly improve the medical care of patients with metabolic disease. Enzyme replacement therapy has showed promising efficacy for lysosomal storage disease, bone marrow transplantation is effective in some disease and gene therapy has been trying for different diseases. The new trials for treatment of the disease will give us promising insight on the disease and most clinicians should have more interest in medical progress of the metabolic disease.

Background: Eckol purified from Ecklonia cava, a brown alga has been known to have cytoprotective effects on some cell lines against oxidants and ionizing radiation. However, there is no study about the effects of eckol on immune cells. Methods: Bone marrow (BM)-derived dendritic cells (DCs) were used to demonstrate the immunomodulatory effects of eckol on DCs, such as viability, the expression of surface markers, allogeneic stimulating capacity using MTI, flow cytometric, $^3H$-thymidine incorporation assay. Results: Eckol did protect DCs against cytokine withdrawal-induced apoptosis in a concentration dependent manner based on MTT assay. And also, it increased the expression of MHC class II and CD86 (B7.2) molecules, maturation markers, on the surface of viable DCs gated in FACS analysis. Furthermore, eckol-treated DCs stimulated the proliferation of allogeneic $CD4^+$ T lymphocytes compared to imDCs in $^3H$-thymidine incorporation assay. $CD4^+$ T lymphocytes activated with eckol-treated DCs produced the larger amount of IFN-${\gamma}$ and IL-4 than those cells with imDCs. Conclusion: Taken together, we demonstrate in this study that eckol, a pure compound of Ecklonia cava, may modulate the immune responses through the phenotypic and functional changes of DCs.

Purified compound with intestinal immune system-modulating properties, GWE-2c, was isolated from methanol extract of Gelidium amansii by sequential procedures with silica gel column, LH-20 Sephadex gel column, and thin-layer chromatographies. In the presence of GWE-2c, strong immunoactivity in Peyers patch cell-mediated bone marrow cells was observed in vitro. In vivo intestinal immune-modulating activity was also enhanced by crude phenolic compound (GWE) of G. amansii in a dose-dependent manner. Investigation of production of several cytokines in Peyer's patch cells upon stimulation with GWE in vivo revealed the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-6 increased. Results suggest that the phenolic compound from G. amansii represents immunopotentiator and biological response modifier at in vitro and in vivo levels.

A literature study on cancer therapy of warm-hot oriental medicine was done, and the results were as follows. 1. In oriental medicine, oncogens are six exopathogens, seven modes of emotion, overwork, pathogenic factors, and especially related with pathologic cold situation. 2. There are many capillaries in tuomr, and because temperature of inner space of tumor is higher than normal organization. Tumor cell has a character which is weak for high temperature. 3. Warm-hot herb drugs have effects of dissipating mass, warming kidney to reinforce yang and dispering, so it has a function of suppressing tumor as well as improving immunity in cancer therapy. 4. In traditional medical books, main prescriptions of cancer therapy are xinzhiyinyanggongjiwan(新製陰陽攻積丸), qianjinxiaoshiwan(千金硝石丸), feiqiwan(肥氣丸), xibenwan(息賁丸), fuliangwan(伏梁丸), beiqiwan, bentunwan(賁豚丸), zengsunwujiwan(增損五積丸), and these are composed of warm-hot herb drugs. 5. In current, the study of warm-hot drugs is progressed in immunological capacity, anti-tumor activity, stimulating bone marrow and regulating hormone secretion. It will be expected that advanced study of these must be accomplished in cancer patients.

Thermal drying is a common process used in the food industry for the modification of agricultural products. However, while various studies have investigated the alteration in physiochemical properties and chemical composition after drying, research focusing on the relationship between different dehydration conditions and bioactivity is scarce. In the current study, we prepared dried ginger under nine different conditions by varying the processing time and temperature and compared their immunomodulatory effects. Interestingly, depending on the drying condition, there were significant differences in the immunestimulating activity of the dried ginger samples. Gingers processed at $50^{\circ}C$ 1h displayed the strongest activation of macrophages measured by $TNF-{\alpha}$ and IL-6 levels, whereas, freezedried or $70^{\circ}C$- and $90^{\circ}C$-dried ginger showed little effect. Similar results were recapitulated in primary bone marrow-derived macrophages, further confirming that different dehydration conditions can cause significant differences in the immune-stimulating activity of ginger. Induction of ERK, p38, and JNK signaling was found to be the major underlying molecular mechanism responsible for the immunomodulatory effect of ginger. These results highlight the potential to improve the bioactivity of functional foods by selectively controlling processing conditions.

Forced orthodontic eruption(FOE) is a non-surgical treatment approach that allows augmenting both soft- and hard-tissue profiles of potential implant sites, by forced orthodontic extrusion of "hopeless" teeth and their periodontal apparatus. By stretching the gingival and periodontal ligament fibers during extrusion, tension is imparted to the entire alveolar socket, stimulating osseous apposition at the alveolar crest. FOE increases the width of the attached gingiva, and the mucogingival junction remains stable when the gingival margin migrates coronally. Based on these effects, FOE of non-restorable teeth prior to implant placement is a viable alternative to conventional surgical augmentative procedures in implant site development. The aim of this case report is to describes coronal soft-tissue augmentation around fractured teeth, which was achieved by FOE before implant placement.

Deer antler tissue contains the most rapidly growing bone in the animal kingdom. Thus, it is likely that growing antler tissue is a rich source of local paracrine bone-stimulating factors. Growth factors, at least the insulin-like growth factor (IGF), control the bone-remodelling process. In this study, we tried to isolate and purify IGF-I from fresh antler tissue by the routine isolation and purification of protein. The purification involved ammonium sulfate precipitation, DEAE-Sepharose CL-60 ion-exchange chromatography, CM-Sepharose CL-6B ion-exchange chromatography, and Sephadex G-50 chromatography. Purified fractions from each step were analyzed by high-performance liquid chromatography (HPLC), SDS polyacrylamide gel electrophoresis (SDS-PACE), Dot-blot, and Western-blot methods. Furthermore, the quantification of partially purified IGF-I was calculated by enzyme-linked immunosorbent assays (ELISA) using antibody to human recombinant IGF-1. SDS-PAGE analysis of the final fraction yielded two molecular bands and the signal band was at 12 kDa on the Western-blot film. This purified IGF-I fraction showed a peak at retention time of eight min. The quantity of IGF-I in 20 g deer antler tissue as starting weight was calculated using a standard curve to be 2910 ng/ml, and total IGF-I amount is 0.291 g. The results show that IGF-I, which can be found in deer antler, can be partially purified and quantified by classic protein isolation methods.
