Purpose : To assess the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor(GM-CSF) in the neutropenia by radiotherapy. Materials and Methods : Eleven patients with various solid tumor were treated with a daily subcutaneous dose of GM-CSF(3-7microgram/kg) for 5days during the radiotherapy. Before and during the course of the study all the patients were monitored by the recording of physical examination, the complete blood count with differential and reticulocyte count and liver function test. Eight patients received prior or concurrent chemotherapy. Results : In 10 patients, the neutrophilic nadir was significantly elevated and the lenght of time that Patients had a neutrophil count below $10^3/mm^3$ a threshold known to be critical to acquiring infective complications was shortened following GM-CSF injection. A significant rise (two fold or greater) of neutrophil count was seen in 10 of 11 patients. In most patients, discontinuation of GM-CSF resulted in a prompt return of granulocyte counts toward baseline. However the neutrophil count remained elevated over $10^3/mm^3$ during radiation therapy, and radiotherapy delays were avoided. Other peripheral blood components including monocytes and platelets also increased after GM-CSF treatment. No significant toxicity was encountered with subcutaneous GM-CSF treatment. Conclusion : GM-CSF was well tolerated by subcutaneous route and induced improvement in the neutropenia caused by radiotherapy.

Hypothyroidism is a common disease of the endocrinal system, characterized by fatigue, cold intolerance, bradycardia, and so on. Subclinical hypothyroidism is a common biochemical abnormality which can be found in routine screening tests of thyroid function. It is defined as an asymptomatic state which characterized by normal free thyroxine(FT4) and elevated thyroid stimulating hormone(TSH) levels. The purpose of this study was to evaluate the effect of treatment with palmijihwang-tang and to observe the changes in triiodothyronine(T3), free thyroxine(FT4), thyroid stimulating hormone(TSH) level and VAS of cold intolerance, hoarseness, dry skin. After the treatment, triiodothyronine(T3) increased from 57.12ng/dl to 120.53ng/dl. Free thyroxine(FT4) increased from 12.59pg/ml to 14.21pg/ml. Thyroid stimulating hormone(TSH) decreased from 10.61mU/L to 1.57mU/L. Cold intolerance, hoarseness and dry skin changed for the better. These results support a role for oriental medical therapy in treating subclinical hypothyroidism. Further case studies of herbal treatment of this ailment are needed.

This study evaluated the change in whitening activity of ${\beta}-glucan$ by gamma-irradiation. Tyrosinase inhibition was significantly increased in the samples with 30, 50, 100 kGy irradiated ${\beta}-glucan$. Melanin synthesis of irradiated ${\beta}-glucan$ was measured from B16BL6 melanoma cell line treated with ${\alpha}-melanin$ stimulating hormone. Melanin synthesis was increased in the ${\alpha}-melanin$ stimulating hormone added group. However, it was decreased in the groups of 30, 50 and 100 kGy gamma-irradiated ${\beta}-glucan$ treated with ${\alpha}-melanin$ stimulating hormone. These results indicate that gamma irradiated ${\beta}-glucan$ may elevate the whitening activity. Therefore, gamma-irradiated ${\beta}-glucan$ could be used for nutraceutical foods in cosmetic industry.

Objectives: The purpose of this study was to investigate the effects of Gardeniae Fructus Water Extract (GF) on the production of inflammatory mediators in RAW 264.7 cell treated with lipopolysaccharide (LPS). Methods: Gradeniae Fructus was extracted with distilled water (2,000 ml) for 2 hours. In order to evaluate cytotoxicity of GF, 3 - (4,5-dimethylthiazol-2-yl) - 2,5 - diphenyltetrazolium bromide (MTT) assay was performed. To investigate antiinflammatory effects, the concentration of nitric oxide (NO) was measured with No assay, calcium (Ca) was measured with Fluo-4 Ca assay, and cytokine was measured by Bio-Plex cytokine assay in RAW 264.7 cell. And when p-value is below 0.05, it is judged to have the significant difference statistically. Results: 1. GF did not show any cytotoxicity. 2. GF suppressed the production of NO and Ca at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 3. GF suppressed the production of interleukin (IL)-$1{\beta}$, IL-10, IL-12p40, macrophage-colony stimulating factor (M-CSF), macrophage inflammatory protein (MIP)-$1{\beta}$ and keratinocyte chemoattractant(KC) at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 4. GF suppressed the production of vascular endothelial growth factor (VEGF), granulocyte-colony stimulating factor (G-CSF) and monocyte cheomattractant protein (MCP)-1 at the concentration of 25, 50 and $100{\mu}g/ml$. 5. GF suppressed the production of granulocyte macrophage-colony stimulating factor (GM-CSF) and regulated on activation, normal T cell expressed and secreted (RANTES) at the concentration of 25 and $50{\mu}g/ml$. 6. GF suppressed the production of MIP-2 at the concentration of 50 and $100{\mu}g/ml$, and tumor necrosis factor (TNF)-${\alpha}$ at the concentration of 50 and $200{\mu}g/ml$. Conclusions: These results suggest that GF has anti-inflammatory effect and immuno-modulating activity.

Purpose: The purpose of this research is to study changes in pituitary hormone in anterior lobe and thyroid hormone before, after, and during recovery time in severe 100 km ultramarathon. Methods: Healthy middle-aged runners (age, $52.0{\pm}4.8$ years) participated in the test. Grade exercise test is done, and then blood is taken from those participants before and after completing 100 km ultramarathon at the intervals of 24 hours (1 day), 72 hours (3 days), and 120 hours (5 days) to analyze their luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and free thyroxine (Free T4). Results: For LH, it decreased more significantly at 100 km than pre-race. However, after 1 day result increased more than that of 100 km. At 3 days, it was significantly higher than pre-race and 100 km, recovering at 5 days. In terms of FSH, it decreased at 100 km, 1 day, and 3 days more than pre-race but recovered at 5 days. TSH was higher at 1 day and 5 days compared to pre-race. T3 was only higher at 100 km than pre-race. T4 was higher till 5 days at 100 km than pre-race. Free T4 increased more significantly at 100 km than pre-race. Conclusion: In terms of severe long distance running, LH and FSH which belong to hormone from anterior lobe as well as T3, T4, and Free T4 which belong to thyroid hormone showed their variation within the standard range. However, TSH showed abnormal increase from enhanced concentration of blood after marathon becoming hyper-activation even during the recovery period.

The elongation of mesocotyl and coleoptile plays important roles in the seedling emergence and stand establishment of dry direct-seeded rice. Experiments were carried out to elucidate the effects of seed-presoaking treatments of GA$_3$ and some inorganic salts on the mesocotyl, and coleoptile elongation of rice. Seed-soaked GA$_3$ promoted the elongation of mesocotyl, but little effect on the coleoptile elongation. The stimulation effects of GA$_3$ were found to be enhanced by addition of CaCl$_2$ However, the sole treatment of CaCl$_2$ showed no stimulating effect on the mesocotyl and coleoptile elongation. Mesocotyl elongation was most prominent in the combined treatments of 50ppm GA$_3$ with 100 mM CaCl$_2$. The synergistic effects of GA$_3$ and CaCl$_2$ on mesocotyl elongation varied with varietal groups. The stimulating effects of GA$_3$ were enhanced significantly by the addition of CaCl$_2$ in japonica varieties, Dongjinbyeo, Ilpumbyeo and Milyang 95, and tall indica variety, Labelle, but not in semidwarf Tongil type varieties, Tongilbyeo, Milyang 23, and Nampungbyeo, and semi-dwarf indica, Short Labelle. The promoting effects of GA$_3$ on the mesocotyl elongation were decreased in proportion to the lowered osmotic potential by PEG 6000 on the contrary to CaCl$_2$ This implies that the synergistic effects of CaCl$_2$ with GA$_3$ on mesocotyl elongation was not caused by osmotic potential lowered by CaCl$_2$ addition but by the salt itself. Salts such as Ca(NO$_3$)$_2$, MgCl$_2$ BaCl$_2$, NaCl, KCl and KNO$_3$ showed the synergistic effects with GA$_3$ on mesocotyl elongation as well. The degree of synergistic effects showed no differences among salts tested, implying that there is no specificity of ions constituting the salts.

Objective : Functional and neural tissue recovery has been reported in many animal studies conducted with stem cells. However, the combined effect of cytokines and stem cells has not yet been adequately researched. Here, we analyzed the additive effects of granulocyte colony-stimulating factor (GCSF) on adipose-derived stem cells (ADSCs) infusion in the treatment of acute spinal cord injury (SCI) in rats. Methods : Four days after intrathecal infusion tubes implantation in Sprague-Dawley rats, SCI was induced with an infinite horizon impactor. In the Sham group (n=5), phosphate-buffered saline was injected 3, 7, and 14 days after SCI. GCSF, ADSCs, and ADSCs with GCSF were injected at the same time in the GCSF (n=8), ADSC (n=8), and ADSC+GCSF groups (n=7), respectively. Results : The ADSC and ADSC+GCSF groups, but not the GCSF group, showed significantly higher Basso-Beattie-Bresnahan scores than the Sham group during 8 weeks (p<0.01), but no significant difference between the ADSC and ADSC+GCSF groups. In the ladder rung test, all four groups were significantly different from each other, with the ADSC+GCSF group showing the best improvement (p<0.01). On immunofluorescent staining (GAP43, MAP2), western blotting (GAP43), and reverse transcription polymerase chain reaction (GAP43, nerve growth factor), the ADSC and ADSC+GCSF groups showed higher levels than the Sham and GCSF groups. Conclusion : Our analyses suggest that the combination of GCSF and ADSCs infusions in acute SCI in the rat does not have a significant additive effect. Hence, when combination agents for SCI stem cell therapy are considered, molecules other than GCSF, or modifications to the methodology, should be investigated.

Objectives : Hibisci Flos has long been used for inflammatory diseases in traditional Korean medicine. However, little scientific investigation has been carried out. The aim of the present study is to investigate the effect of Hibisci Flos water extract (HF) on inflammatory cytokines production in Raw 264.7 cells stimulated by lipopolysaccaride (LPS). Method : HF was prepared by extracting with boiling water for 2 hours. We observed the cell viability of mouse macrophage Raw 264.7, the production of nitric oxide (NO) and the inflammatory cytokines such as interleukin (IL)-4, IL-5, IL-10, IL-15, tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interferon-gamma (IFN-${\gamma}$), vascular endothelial growth factor (VEGF), granulocyte macrophage-colony stimulating factor (GM-CSF), and macrophage colony-stimulating factor (M-CSF) in Raw 264.7 cells stimulated by LPS. Result : The MTT assay was carried out to check the cellular toxicity of HF. No significant toxicity was observed in the experiment. HF significantly inhibited the increase of NO in the macrophages induced by LPS after 24 hour treatment. HF significantly inhibited the production of IL-4, IL-5, IL-10, IL-15, TNF-${\alpha}$, IFN-${\gamma}$, VEGF, GM-CSF and M-CSF in the Raw 264.7 cells induced by LPS in the concentration of $25{\mu}g/mL$ or higher. Conclusion : These results suggest that HF might have regulatory effects on LPS-induced inflammatory cytokine production, which might explain its beneficial effect in the treatment of inflammatory disease.

Although polysaccharide is believed to play an important role in the medicinal effect of Dendrobium chrysotoxum Lindl (DCL), its role as an antioxidant and in anti-hyperglycemic induction was not reported. In this study, polysaccharide with molecular weight of approximately 150 kDa, herein named DCLP, was isolated from the stem of DCL, and its antioxidative, hypoglycemic and immune stimulating effects were evaluated using various in vitro and in vivo assay systems. DCLP inhibited hydroxyl radicals ($^{\cdot}$OH)-mediated deoxyribose degradation by scavenging hydroxyl radicals directly as well as by chelating iron ions. DCLP also showed dose-dependent scavenging activity on superoxide anions ($O_2^{{\cdot}-}$) and offered significant protection (p < 0.001) against glucose oxidase-mediated cytotoxicity in Jurkat cells. DCLP had immune stimulating effects, as evidenced by the DCLP-mediated increases in the level of DNA synthesis, viability, and cytokine secretion in mouse lymphocytes. Moreover, oral administration of DCLP produced a significant reduction in blood glucose level in alloxan-induced diabetic mice. These findings suggest that DCLP has a potential utility in treating patients who require enhanced antioxidation, immune function and/or hypoglycemic activity.
