Objective: We have evaluated UDHA into the joint for its effectiveness on immune responses to CII in the rat CIA. In an attempt to gain further insight into the mode of action of UDHA, we also investigated the effects of UDHA on the incidence and development of arthritis in rat CIA with 2 different regimens: (1) started prior to a primary immunization, (2) started on the day of a primary immunization. Methods : Male rats were immunized with an emulsion of $200\;{\mu}g/100g$ of CII and complete Freund's adjuvant (CFA). The rats were then given intraperitoneal(i.p) stimulation of Ulmus davidiana Planch herbal acupuncture(UDHA) or saline during the experiment. Lymph node cells were obtained from rats 14 days after immunization and cultured in vitro with CII. When compared with rats treated with saline as control, UDHA at doses of more than $20\;{\mu}g/100\;g$ rat once a day for 7 days inhibited the ability of inguinal lymph node cells to produce T cell cytokines interleukin-$1{\beta}$, tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$. When rats were injected intraperitoneally with SRBC, hemaglutination titers in UD-treated and control rats did not differ significantly when low doses of UD was given to rats. However, i.p injection of UD at doses of more than $10\;{\mu}g/100\;g/day$ for 7 days slightly suppressed antibody production. Results : The present results show that treatment with UDHA can inhibit the onset and development of arthritis and the immune responses to collagen. Conclusion: Therapeutic i.p injection with UD affect the clinical course of the disease and the immune responses to CII.

There are various treatment methods including barrier membranes in attaining periodontal regeneration and regaining the function of destructed periodontal tissues due to periodontal disease. Barrier membranes consist of non-Resorbable and resorbable types such as Dura mater and $Guidor^{(R)}$ used in the treatment of intrabony defects and classII furcation defects have been shown to be effectively increased the amount of new bone and cementum.In our study we used premolars with class III furcation defects created by removing the bone 4mm apically from CEJ in adult dogs and placed resorbable membrane Dura mater and $Guidor^{(R)}$ for the test group and flap operation was carried out for the control groups. The effect of membrane on junctional epithelium, alveloar bone, cementum, and gingival connective tisssue in the regeneration and healing potential of periodontal tissues was evaluated and healing results were evaluated histologically and histometrically 8 weeks following the surgical procedure. 1. In the clinical observation, there was no exposure of furcation defects in the control group, whereas slight membrane exposure was noted in the test group. 2. New bone was formed up to the level of the notch in the control group, whereas in the test group new bone formation was observed above the level of the notch. 3. New cementum was formed in both groups of the experiment. 4. The connective tissue observed between the new cementum and new bone in the test group were functionally orientated, compared to the irregular formation of connective tissues found in the control group. 5. Root resorption or ankylosis was not observed in any of the groups 6. The mean and median of the control group were 4.31% and 2.23% and for the Dura mater group were 27.85% and 15.57% respectively. There was no significant difference between Dura mater and the control group. 7. The mean and median of the control group were 4.31% and 2.23% and for the $Guidor^{(R)}$ group were 37.27% and 37.19% respectively. There was a significant difference in these two groups(P$Guidor^{(R)}$ were 37.27% and 37.19%. There was no significant difference between the two test groups. Thus, by using Dura mater and Guidor in classIII furcation defects, the predictable amount of periodontal ligament and alveolar bone regeneration may result.

The purpose of this study was to examine the effects of anti-sperm antibody (ASA) on the fertilization processes using conventional IVF and ICSI procedure in human and hamster oocytes. In human IVF, we have observed restricted fertilization with sperm testing positive for ASA. ($23{\sim}90%$ IgA, 60-97 % IgG). However, if ICSI was perform in the next IVF cycle with the same patients, we could successfully fertilize the oocytes (37%; p<0.001), thus achieving pregnancy and delivery. When the sperm were cocultured in medium containing ASA, there were binding of ASA to sperm surface. In addition, the mean rate of the acrosomal reaction in an in vitro acrosome reaction test was lower for Ab-bound sperm (43.5%) than for Ab-free sperm group (51.3%, p<0.05). We used human sperm and hamster oocytes to confirm the negative effects of the ASA on fertilization. The sperm and/or oocytes have been expose to medium containing ASA before IVF and ICSI. In this experiment, the ASA was bound to the oocyte and sperm surface. The following results were obtain by using various combinations of ASA free or ASA bound sperm with ASA free or ASA bound oocytes for IVF. When ASA free sperm were inseminate with ASA free and ASA bound hamster oocytes, the fertilization rates are 89.6% and 74.3% respectively. However, when ASA bound human sperm were use the results were 62.5% and 55.6% respectively. These shows the fertilization rate was significantly decreased in both ASA bound and ASA free oocytes when using ASA bound sperm. No difference found when ASA are present on the oocyte surface. When the hamster oocytes was treated by ICSI with ASA free or ASA bound human spermatozoa, no significant difference was found. These results showed that ICSI is the most promising method for couples who fertilization was not possible by conventional IVF because of ASA.

The research method of 'the grafing I-ching(周易) and oriental medicine'(醫易會通) has been handed down for more than 2000 years to interpret the theory of the medicine by using the system of the ideology and the category of I-ching(周易). Many skillful doctors form the past have developed and advanced the oriental medicine by studying the 'the grafing I-ching(周易) and oriental medicine'(醫易會通) and wrote many theories and had experiment on clinical studies. From many theories of 'the grafing I-ching(周易) and oriental medicine'(醫易會通), I believe using the ideology and the category of eight trigrams(八卦) system to study the internal organs(臟腑) has a great importance. For eight trigrams(八卦) is the nucleus or the basic of I-ching(周易) and the internal organs (臟腑) are the main system of the body. Therefore grafting eight trigrams(八卦) and the internal organs (臟腑) theory has a meaning of grafting I-ching(周易) and the main point of the oriental medicine. But the uncertainties of the theories between doctors still exists and there's no unified theories in matching eight trigrams(八卦) and the internal organs(臟腑). This tells us that the most important part of the 'the grafing I-ching(周易) and oriental medicine'(醫易會通) theory is not logically organized. Therefore the author realized the necessity of the study about grafting eight trigrams(八卦) and the intimal organs (臟腑) theory, Also in order to confirm the significance of the result of the research, first of all there needs to be a research that applies it to the meathod of the mental cultivation(精神養生法), Health preservation(養生) is the basic idea of the oriental medicine and among health preservation(養生), the meathod of the mental cultivation(精神養生法) is most important.

This study's purpose is improve image quality to keep accurate tube angle in order to recognize distortion degree conditions by patient's position or tube angle and to provide exact clinical informations when taking chest AP projection for patient which have L-tube in stomach. The experimental equipment was ELMO-T6S by SHIMADZU corporation, then we put L-tube which attached 1 mm gap scales ruler on chest phantom surface. The experiment set by 90 kVp, 4 mAs, 120 cm distance. Each phantom position which changed supine, 30degree, 45degree, 60degree on the table exposured direct, ${\pm}5degree$, ${\pm}10degree$, ${\pm}15degree$ to head and feet directions. As a result, L-tube tip's position was changed by patient's position and tube angle. When patient's position is supine, tip's position change was lower than 30degree, 45degree, 60degree. We have to adjust patient's position or tube angle in order to occur image distortion by fault tube angle when confirming correct position L-tube tip through chest x-ray. Also, Radiological technologist try to make accurate evaluation index for satisfied L-tube insertion.

By accessing the current status of FPD system use in the hospitals located in Seoul and Gyeonggi Province as well as the entrance skin dose and the image quality evaluation realized by C-D Phantom, and the image assessment by the medical professionals regarding the radiography for the extremity, the following results were derived. 1. According to the evaluation made in the actual use of FPD system (12 machines), the grid ratio varied from 8:1 to 13:1, and 6 machines used the grid ratio with 12:1, realizing the largest number. Among the machines, there were 8 machines that allowed a removable grid while 3 machines did use a removable grid (25.0%). 2. When it came to the equipments used for the experiment, it showed that the amount of the entrance skin dose increased from 4.13 times up to 4.79 times with the grid use. 3. The difference in the entrance skin dose depending on the changes in the exposure condition(0.5times or 2.0times) was not significantly different regardless of the patients' thickness. 4. In terms of the image quality depending on C-D Phantom, the grid use was distinguished well. However, the images were well distinguishable as the exposure condition got increased. 5. In the clinical assessment, the grid use was less effective for the Hand PA, which was considered to shoot a thin body part. It was evaluated that the grid use was preferred for the Knee AP, which was shooting for a relatively thick body part. Nonetheless, 3 out of 5 people said that they would not use the grid if the entrance skin dose to reduced.

Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) have been as eye washes of inflammatory eye disease in the oriental medicine. Especially Jinpisan(秦皮散) has been used for the disease which is similar to Peudomonas aeruginisa keratitis. This research was attempted to investigate the effect of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散), on Peudoronas aeruginisa keratitis. Pseudomonas aeruginosa keratitis causes a deep rapid intense ulceration which often leads to perforation of the cornea within 48 hours. In this research, we induced keratits in the rabbits by inoculating Pesudomonas aeruginosa(9027) and observed the effect on the keratitis and the irritation against the external eye. Also we mesured the minimum inhibitory consentration(MIC) of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) by agar diliution method and the anti-bacterial activites by disk method. The tested bacteria were as follows : a) Pseudomonas aeruginosa (9027), b) Streptococcus pneumoniae(6303), c) Staphylococcus epidermidis(12228), d) Staphylococcus aureus(6538P). The results were as follows ; 1. The groups which were applied eye washes of Fraxini Cortex, Jinpisan reavealed a significant effect, but the group applied eye wash of Coptidis Rhizoma reveaded no effect on Pseudomonas aeruginosa keratitis. 2. Applying eye washes of Coptidis Rhizoma, Fraxini Cortex, Jinisan revealed an irritation against external eyes. 3. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylucoccus aureus by agar diliution method 4. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. 5. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method 6. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Sireptococcus pneumoniae, Staphylococcus epidermidis, Staphy1ococcus aureus by disk method. 7. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method. 8. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. According to the above results, Fraxini Cortex, Jinpisan(秦皮散) are recognized to have an effective treatment on the Pesudomonas aeruginosa keratitis, so this experiment is thought to be a basic ingredient in proving the effect of Fraxini Cortex, Jinpisan which is applied many in documents and clinical medicine. In the comparison of anti-bacterial activity and results of treatment on the Pesudomonas aeruginosa keratitis, Jinpisan(秦皮散) was more effective than Coptidis Rhizoma, Fraxini Cortex.

The purpose of this study was to examined whether high voltage pulsed current stimulation(HVPCS) enhances the migration and proliferation of fibroblasts from tendon biopsies to provides evidence that the cellular activities of fibroblast are enhanced by HVPCS. Flexor digitorum profundus tendon of chickens were excised, biopsied and cultured in M199 medium for a day. The biopsies through which a cathodal HVPC with 100 pps, 50 V for 30 minutes was passed in medium. A day after treatment, the biopsies embedded in fibrin clot were covered by the addition of 1ml of M199 medium to the well, and placed in the $CO_2$ incubator for the duration of the experiment. The migration distance of cells from tendon biopsies were measured at 6 days after treatment, and proliferation of cells from tendon biopsies were measured at 7 days after treatment. The migration distance of cells from tendon biopsies in the HVPCS group demonstrated significantly greater than the shame treated control group (t=-2.675, p<0.05). Also HVPCS had significantly increased optical density of fibroblasts from tendon biopsies (t=-2.136, p<0.05). These results indicate that the HVPCS with 100pps, 50V for 30minutes enhanced either the migration and proliferation of fibroblast from tendon biopsies. These results supposed that the HVPCS activates cellular responses in fibroblasts from tendon biopsies. This suggests that enhanced the migration and proliferation of fibroblast by HVPCS may be one of the mechanism involved in tendon healing.

Hwanhonsan has been used for curing tumor as a Oriental medicine without any experimental evidence to support the rational basis for their clinical use. This experiment was carried out to evaluate the possible therapeutic or antitumoral effects of Hwanhonsan extract against cancer, and to study some mechanisms responsible for its effect. Some kind of tumors were induced by the typical application of 3-methylcholanthrene(MCA) or by the implantation of malignant tumor cells such as leukemia cells(3LL cells) or sarcoma cells(S180 cells) and FasII cells. Treatment of the Hwanhonsan extract(daily 1 mg/mouse, i.p.) was continued for 7 days prior to tumor induction and after that the treatment was lasted for 20 hrs. Against squamous cell carcinoma induced by MCA, Hwanhonsan decreased. not only the frequency of tumor production but also the number and weight of tumors per tumor bearing mice(TBM). Hwanhonsan also significantly suppressed the development of 3LL cells and S180 cells implanted tumors by frequency and their size, and some developed tumors were regressed by the continuous treatment of Hwanhonsan extract into TBM. However, when tumor was induced by FsaII cells implantation, the growth of implanted cells in mice was delayed by the water extract of Hwanhonsan until 7 days and then rapid growth ensued. In vitro treatment of Hwanhonsan extract had no inhibitory effect on the tumor induced by some kind of cell lines such as A431 cells strain but it significantly inhibited the proliferation of 3LL cells, S180 cells. These results suggested that Hwanhonsan extract exhibited a significant prophylactic benefits against tumors and its antitumor activity was manifested depending on the type of tumor cells.

This research investigates the effect of the Chaenomelis fructus(CMF) on Alzheimer's disease. Specifically, the effects of the CMF extract on (1) >$IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ mRNA of PC-12 cells treated with LPS; (2) amyloid precursor proteins(APP), acetylcholinesterase(AChE), and glial fibrillary acidic protein(GFAP) mRNA of PC-12 cells treated with CT-105; (3) the AChE activity and the APP production of PC-12 cell treated with CT-105; (4) the behavior of AD mice with ${\beta}A$; (5) expression of $IL-1{\beta}$, $TNF-{\alpha}$, MDA, $IL-1{\beta}$ mRNA, $TNF-{\alpha}$ mRNA, and ROS; (6) the infarction area of the hippocampus, and brain tissue injury in Alzheimer's diseased mice induced with ${\beta}A$ were investigated. The results were summarized as follows; 1. The CMF extract suppressed the expression of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ mRNA in THP-1 cells treated with LPS. 2. The CMF extract suppressed the expression of APP, AChE, and GFAP mRNA in PC-12 cells treated with CT-105. 3. The CMF extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT-105. 4. A significant inhibitory effect on the memory deficit was shown on the CMF extract group of the mice with Alzheimer's disease induced by ${\beta}A$ in the Morris water maze experiment, which measured stop-through latency, and distance movement-through latency. 5. The CMF extract suppressed the over-expression of $IL-1{\beta}$ protein, $TNF-{\alpha}$ protein, MDA, $IL-1{\beta}$ protein, mRNA, $TNF-{\alpha}$ mRNA, CD68/GFAP, and ROS in the mice with Alzheimer's disease induced by ${\beta}A$. 6. The CMF extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer’s disease induced by ${\beta}A$. These results suggest that the CMF extract may be effective for the treatment of Alzheimer’s disease. Investigation into the clinical use of the CMF extract for Alzheimer's disease is suggested for future research.
