This study demonstrated the immunological effects of methanol extracts from Doenjang added with wild plants (Pteridium aquilinum and Aster scaber) on bone-marrow derived macrophages and mouse splenocytes. Doenjang (DJ) and wild plant added Doenjang (WPDJ) extracts were treated to bone-marrow derived macrophages (BMDM) and splenocytes, and cell proliferation and cytokine production were measured. Cell proliferation of BMDM and splenocytes was more highly elevated in the WPDJ-treated group compared to the DJ-treated group. Cytokine [tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, IL-$1{\beta}$, IL-10, and IL-12] production in BMDM also significantly increased in the WPDJ-treated group. Similarly, in the case of cytokine production in splenocytes, WPDJ treatment highly increased production of Th 1 type cytokines [interferon (IFN)-${\gamma}$ and IL-2] but did not affect production of Th 2 type cytokines (IL-4). These results suggest that wild plants could improve the immunomodulatory activity of Doenjang and may be effective for the development Doenjang.

Objectives To evaluate the neuroprotective effects of Hyangsayangwi-tang (HY), a Korean traditional medicinal prescription in a Parkinson's disease mouse model. Methods Four groups(each of 10 mouse per group) were used in this study. The neuroprotective effect of HY was examined in a Parkinson's disease mouse model. C57BL/6 mouse treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 30mg/kg/day), intraperitoneal (i.p.) for 5 days. Slow behavioral responses and memory disorder is the major clinical symptoms of PD. In order to investigate the effect of HY on recovery of behavioral deficits and memory, we examined the motor function and memory by using Morris water maze and Forced swimming test. Ischemic mouse brain stained with TTC(2,3,5 triphenyl tetrazolium chloride) in the MPTP-induced Parkinson's disease to find out ischemia and tissue damage in mouse. The convenient, simple, and accurate high-performance liquid chromatography (HPLC) method was established for simultaneous determination of neurotransmitters in MPTP-HY group. To measure the amount of dopamine in mice brain, striatum-substantia nigra, was examined by Bradford assay. Immunohistochemistry was examined in the MPTP-induced Parkinson's disease (PD) mouse to evaluate the neuroprotective effects of Hyangsayangwi-tang on hippocampal lesion, ST and SNpc. Results and Conclusions Hyangsayangwi-tang (HY) prevents MPTP-induced loss of serotonin, hippocampus and TH-ir cell.

Objectives The suppressive effect of CSBHT has been mysterious. Thus, the present study is designed to investigate the suppressive effect and its mechanism. Methods To investigate the anti-allergy effect from ChungShimBoHyeolTang(CSBHT), RBL-2H3 cell was used and examined by Real-Time PCR, and IL-4 and IL-13 from RBL-2H3 was examined by ELIS. In addition, GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, c-Jun, NF-${\kappa}B$ p65 transcription factors of RBL-2H3 mast cell were examined by Western Blotting. Also, OVA/alum-sensitized mice were orally administrated CSBHT and serum OVA-specific IgE production, IL-4, and IL-13 production in splenocytes supernatant were examined. Results As a result of treating with CSBHT extract, RBL-2H3 mast cells significantly suppressed the IL-4 and IL-13 mRNA expression and IL-4 and IL-13 production. Western blot analysis of transcription factors involving IL-4 and IL-13 expression also revealed a prominent decreases of mast cell's specific transcription factors including GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos, and NF-${\kappa}B$ p65. Also, examining the mice, administration of CSBHT suppressed the amount of OVA-specific IgE in OVA/alum-sensitized mice and IL-4 and IL-13 production in splenocytes supernatant. Conclusions The study suggested that the anti-allergic activities of CSBHT suppresses IL-4 and IL-13 production from the Th2 cytokines by suppressing transcription factors as GATA-1, GATA-2, NFAT-1, NFAT-2, c-Fos and NF-${\kappa}B$ p65 in mast cells.

Objective : Adrenal medullary chromaffin cells are known to release analgesic substances such as opioides and catecholamines. Transplantation of them is a novel method that challenges current approaches in treating chronic pain. The transplantation of xenogeneic chromaffin cells into the central nervous system(CNS) supply antinociception in animals. In this study, we investigated the analgesic effects of rat adrenal medullary chromaffin cells transplanted into the CNS of the mouse. To study the antinociceptive efficacy of transplanted chromaffin cells, the survival of rat adrenal medullary chromaffin cells transplanted into the CNS of mouse was determined. Methods : The adrenal medullary chromaffin cells isolated from rat were transplanted into the striatum of mouse. These cells were confirmed of the release of Met-enkephalin and Leu-enkephalin by HPLC, and immunoblots for tyrosine hydroxylase(TH). Two weeks after transplantation, we performed immunohistochemistry for TH to determine the survival of implanted cells and assessed pain sensitivity at the same time. Results : The isolated rat adrenal medullary chromaffin cells were positive for anti-TH antibody and released Met-enkephalin and Leu-enkephalin more than rat endothelial cells. Transplanted rat chromaffin cells were stained with anti-TH antibody in striatum of mouse after 2 weeks. Pain sensitivity was reduced on the chromaffin cell-transplanted mouse compared to endothelial cell-transplanted mouse by the hot plate test. Conclusion : These results suggest that the rat chromaffin cells were suitably transplanted into the CNS of mouse. This approach could be used as a therapy for reducing of chronic pain induced by cancer or neuronal injury.

Purpose : Treatment of giant cell tumor of distal radius can be treated in several ways according to the agressiveness of the tumor. We treated 3 cases of widely involved giant cell tumor of distal radius with wide resection and proximal fibular graft and report the results with review of literatures. Material and Method : We have treated 3 cases of giant cell tumor of the distal radius since last 1990. Among 3 cases, two cases were grade III radiologically and treated by wide resection of distal radius and vascularized proximal fibular graft, and one case, grade II radiologically, treated by distal radial resection and non-vascularized proximal fibular graft. We followed up clinical results of above three cases 9 years, 12 years and 2 years. Result : In all three cases, tranplanted fibula graft showed solid union but grade III tumors recurred at 4 year and 6 year postoperatively. One of the case which recurred 4 year later was treated with secondary wide resection and wrist fusion with autogenous iliac bone graft, and didn't show any recurrent finding for these 5 years after re-operation. And another grade III, which recurred at 6th post-operative year, is under follow-up for 6 years after recur without 2nd operation. Grade II case didn't show any recurrent findings on 2 year follow-up. Conclusion : Grade III cases recurred at 4 year and 6 year follow-up. The cause of recurrence was thought to be invasion of remaining tumor cell in the soft tissue. To prevent recurrence, complete resection of primary tumor was necessary.

Papilloma is the common benign tumor of the larynx and the incidence of its malignant change was variable. The authors recently experienced 2 cases of squamous cell carcinoma of the larynx which were considered to be transformed from laryngeal papilloma. Case 1. A 58 year old male patient visited O.P.D. of Department of Otolaryngology of Busan National University Hospital, because of hoarseness for 3 years on May 13th, 1980. At that time, local finding of indirect laryngoscopy revealed whitish hypertrophic papillomatous mass on both vocal cords and anterior commissure, and dirty gray white pseudomembrane on left aryepiglottic fold, and the result of biopsy was squamous cell papilloma. So the laryngeal papilloma was removed under suspension laryngoscopy and then he had no specific treatment in spite of being recommended 5-FU topical spray. On March 5th, 1981, he visited O.P.D. again because of progressive exacerbation of hoarseness with mild dyspnea and histopathological finding was revealed squamous cell carcinoma of the larynx. Seven days later from that day, he visited emergency room due to severe dyspnea, and emergency tracheostomy was performed on sitting position. On April 7th 1981, total laryngectomy was performed successfully and postoperative irradiation therapy was recommended. Case 2. A 47 year old male patient visited our O.P.D. because of hoarseness for 5 years on Sep. 27, 1978. At that time, local finding of indirect laryngoscopy revealed papillomatous mass on left vocal cord and left ventricle and result of biopsy was squamous cell papilloma. So he had been treated with 11 times removal of papilloma, topical spray of 5-Fu and estrogen for 3 years, but the papilloma had been recurred. On Sep. 9th, 1981, he visited O.P.D. because of severe dyspnea and emergency tracheostomy and biopsy was performed. The result of biopsy was squamous cell carcinoma of larynx and total laryngectomy was performed successfully.

In this study, the $LiCoO_2/LiNi_{1/3}Mn_{1/3}Co_{1/3}O_2$ mixed cathode electrodes were prepared and their electrochemical performances were measured in a high cut-off voltage. As the content of $LiNi_{1/3}Mn_{1/3}Co_{1/3}O_2$ increased in a mixed cathode, the reversible specific capacity and cycleability of the electrode enhanced, but the rate capability was deteriorated. On the contrary the rate capability of the cathode enhanced, but the reversible specific capacity and cycleability were deteriorated, increasing the content of $LiCoO_2$ in the mixed cathode. The cell of $LiCoO_2/LiNi_{1/3}Mn_{1/3}Co_{1/3}O_2$ ($50:50 wt\%$) mixed cathode delivered a discharge capacity of ca. 168 mAh/g at a 0.2 C rate. The capacity of the cell decreased with the current rate and a useful capacity of ca. 152 mAh/g was obtained at a 2.0 C rate. However, the cell showed very stable cycleability: the discharge capacity of the cell after 20th charge/discharge cycling maintains ca. 163 mAh/g.

Purpose: To investigate the expression of bone morphogenetic protein (BMP)-2/4 during eary tooth development after irradiation and calcium-deficient diet. Materials and Methods: The pregnant three-week-old Sprague-Dawley rats were used for the study. The control group was non-irradiation/normal diet group (Group 1), and the experimental groups were irradiation/normal diet group (Group 2) and irradiation/calcium-deficient diet group (Group 3). The abdomen of the rats at the 9th day of pregnancy were irradiated with single dose of 350 cGy. The rat pups were sacrificed at embryonic 18 days, 3 days and 14 days after delivery and the maxillae tooth germs were taken. The tissue sections of specimen were stained immunohisto-chemically with anti-BMP-2/4 antibody. Results: At embryo-18 days, immunoreacivity for BMP-2/4 of the Group 1 was modetate in stratum intermedium of dental organ and weak in dental papilla and dental follicle, but that of Group 2 was weak in cell layer of dental organ, and no immunoreacivity was shown in dental papilla and dental follice of Group 2 and in all tissue components of the Group 3. At postnatal-3 days, immunoreacivity for BMP-2/4 of the Group 1 was strong in cell layer of dental organ, odontoblasts and developing alveolar bone, but that of Group of 2 and Group 3 was weak in odontoblasts and developing alveolar bone. At postnatal-14 days, immunoreacivity for BMP-2/4 of the Group 1 was strong in newly formed cementum, alveolar bone and odontoblasts, but that of Group 2 was weaker than that of Group 1. In the Group 3, tooth forming cell layer showed weak immunoreactivity, but other cell layers showed no immunoreactivity. Couclusion : The expression of bone morphogenetic protein (BMP)-2/4 during early tooth development was disturbed after irradiation and calcium-deficient diet.

Ten Australian Stock Horses colts (five yearling and five 3-year old colts) of which 2 yearlings and 2 three year old colts served as control animals while 3 yearlings and 3 three year old colts received two GnRH immunizations within 4 weeks interval were used in this study. By the 5th to 6th week after immunization, the GnRH antibody titres in the plasma rose above 1:1000 and attained peak levels of 1:6500 by the 8th week and gradually declined to about 1:3000 by the 10th week in both the age groups. The testosterone and androstenedione concentrations of the control colts in both age groups were significantly greater (p<0.05) than that of the vaccinated groups. During the immunosuppression period, the vaccinated colts behaved like geldings. Semen could not be collected from 2 of the 3 three-year old vaccinated colts. The testicular dimensions, testicular weight, parenchymal weight, seminiferous tubule volumes, interstitial space volumes, Leydig cell volume, seminiferous tubule % of the control colts were significantly greater than those of the vaccinated colts in both the age groups. The 3-year old control colts had a significantly (p<0.05) greater % of Leydig cells than the control and vaccinated 1-year old colts. There was arrest of spermatogenesis with complete absence of sperm in the testes of the vaccinated colts while there was various stages of spermatogenesis in those of the control colts. Morphometric analysis demonstrated that the 3-year old colts had significantly (p<0.05) greater DSP/gm of testis and DSP/testis than those of the 1-year old control colts. This study elucidated that the GnRH immunization could suppress the testicular function of the 3-year old and yearling colts.

Allergic asthma is one of the most enduring diseases of the airway. The T-helper cells and regulatory T-cells are critically involved in inflammatory responses, mucus hypersecretion, airway remodelling and in airway hyper-responsiveness. Cigarette smoke (CS) has been found to aggravate inflammatory responses in asthma. Though currently employed drugs are effective, associated side effects demand identification and development of novel drugs with negligible or no adverse effects. Rutin, plant-derived flavonoid has been found to possess antioxidant and anti-inflammatory effects. We investigated the ability of rutin to modulate T-cells and inhibit inflammation in experimentally-induced asthma in cigarette smoke exposed mice. Separate groups of neonatal mice were exposed to CS for 10 days from post-natal days 2 to 11. After 2 weeks, the mice were sensitized and challenged with ovalbumin (OVA). Treatment group were given rutin (37.5 or 75 mg/kg body weight) during OVA sensitization and challenge. Rutin treatment was found to significantly inhibit cellular infiltration in the airways and Th2 and Th17 cytokine levels as well. Flow cytometry revealed effectively raised $CD4^+CD25^+Fox3^+$ Treg cells and supressed Th17 cell population on rutin treatment. Airway hyper-responsiveness observed following CS and OVA challenge were inhibited by rutin. $NF-{\kappa}B$ and iNOS, chief regulators of inflammatory responses robustly activated by CS and OVA were down-regulated by rutin. Rutin also inhibited the expression of matrix metalloproteinase 9, thereby aiding in prevention of airway remodelling in asthma thereby revealing to be a potent candidate in asthma therapy.
