Stable Compression Fractures(SCF hereafter) are most often caused by trauma such as traffic accidents. These SCFs usually occur in the thoracic and lumbar regions of the spinal cord. Human life spans have increased as a result of medical advances, which in turn has led to an increase in the elderly population. SCFs are divided into the categories of stable and unstable. The categories are determined through X-rays and P/Ex tests. The D.I.T.I. is then used to diagnose the severity and prognosis of the fracture injuries, and it allows an objective evaluation of the symptoms. This author researched 40 patients who were treated at Wonkwang University Oriental Medical Center from October 1995 to December 1996. The patients were diagnosed by X-ray as having SCFs and treated primarily with acupuncture. Both the changes in D.I.T.I. and patients' self-diagnoses of their conditions before and after treatment yielded the meaningful results which have been presented here. 1. 75% of those who suffer from Stable Compression Fractures are 60 years of older. Of those, the ratio of male to female is 1 to 4. This is due in part to the fact that many elderly women seek Oriental medicine treatment for conditions associated with advanced age. 2. 53.3% of these injuries occurred between T11 and L2. 3. 65% of patients were hospitalized for 10 to 29 days, and then able to be treated on an outpatiens basis. 4. The D.I.T.I. results showed 50% below $0.2^{\circ}C$, 30% between 0.3 and $0.5^{\circ}C$, 10% between 0.5 and $0.7^{\circ}C$, 10% between 0.7 and $0.9^{\circ}C$, and 0% over $0.9^{\circ}C$. 5. The results of treatment using Modified Evaluation System in Thoracolumbar Vertebral Fractures Method showed that 55% of patients achieved excellent recovery and 40% achived good recovery. After comparing the D.I.T.I. results before and after treatment, we found 50% of patients showed excellent recovery $({\Delta}T{\leq}0.2)$ and 40% showed good recovery$(0.2<{\Delta}T{\leq}0.5)$.

Scabraside D, a sulfated triterpene glycoside, was extracted from the sea cucumber Holothuria scabra. It shows anti-proliferation in many of cancer cell lines, but the function and mechanisms of action of scabraside D in human cholangiocarcinoma (HuCCA) have not previously determined. In this study, we investigated the activity of scabraside D on HuCCA cell apoptosis, lymphangiogenesis and metastasis in a nude mouse model. Scabraside D induced signs of apoptosis, such as cell shrinkage, nuclear condensation, nuclear fragmentation and DNA fragmentation on TUNEL assays, while effectively decreasing expression of BCl-2 but increasing caspase-3 gene level expression. Immunohistochemistry revealed that scabraside D significantly reduced lymphatic vessel density (LVD). Moreover, scabraside D treatment significantly decreased VEGF-C, MMP-9 and uPA gene expression, which play important roles in the lymphangiogenesis and invasion of cancer cells in metastasis processes. Quantitative real-time PCR showed that scabraside D significantly decreased iNOS and STAT-3 gene expression. This study demonstrated that scabraside D plays a role in activation of HuCCA tumor apoptosis and inhibition of lymphangiogenesis, invasion and metastasis through decreasing BCl-2, MMP-9, uPA and VEGF-C and increasing caspase-3 expression by suppression of iNOS and STAT-3 expression. Therefore, scabraside D could be a promising candidate for cholangiocarcinoma treatment.

It is widely accepted that smooth muscle contraction is triggered by intracellular $Ca^{2+}$ ($[Ca^{2+}]_i$) released from intracellular $Ca^{2+}$ stores such as sarcoplasmic reticulum (SR) and from the extracellular space, The increased $[Ca^{2+}]_i$ can phosphorylate the 20-kDa myosin light chain ($MLC_{20}$) by activating MLC kinase (MLCK), and this initiates smooth muscle contraction. In addition to the $[Ca^{2+}]_i$-MLCK-tension pathway, a number of intracellular signal molecules, including mitogen-activated protein kinase (MAPK), protein kinase C (PKC), phosphatidylinositol 3-kinase (PI3K), and Rho-associated coiled coil-forming protein kinase (ROCK), play important roles in the regulation of smooth muscle contraction. However, the mechanisms regulating contraction of caldesmon (CaD), actin-binding protein, are not entirely elucidated in the presence of $Ca^{2+}$. It is known that CaD tightly interacts with actin and inhibits actomyosin ATPase activity. Therefore, the purpose of the present study was to investigate the roles of $Ca^{2+}$-dependent CaD in smooth muscle contraction. Endothelin-1 (ET-1), G-protein coupled receptor agonist and vasoconstrictor, increased both vascular smooth contraction and phosphorylation of CaD in the presence of $Ca^{2+}$. These results suggest that ET-1 induces contraction and phosphorylation of CaD in rat aortic smooth muscle, which may he mediated by the increase of $[Ca^{2+}]_i$.

Objective : In order to investigate the curative effect of Jucha-whan on the protective liver of guinea pigs induced by $CCl_4$ and d-galactosamine, serum transaminase(GOT, GPT), lactic dehydrogenase(LDH), alkaline phosphatase(ALP), glutathione S-transferase(GST), superoxide dismutase(SOD) were used to measure enzyme activities and lipid peroxide level. Method : The subject animals were divided into 5 groups; a control group(untreated), a subject group(administered with 0.9% Saline solution), a sample I (500mg/kg administered), sample II group (1000mg/kg administered), positive control group(administered with 200mg/kg silymarine). Result : The inhibitory effects on the serum GOT, LDH, ALP, SOD and Lipid peroxide level activities in protective liver of mice induced by $CCl_4$ were noted both in the sample I group and sample II. The inhibitory effects on the serum GPT activities in protective liver of guinea pigs induced by $CCl_4$ were noted in sample II group, but it was not noted in the sample I. The inhibitory effects on the GST activities in protective liver of guinea pigs induced by $CCl_4$ were not noted in both sample I and sample group II. The inhibitory effects on the serum GOT, GPT activities in protective liver of guinea pigs induced by d-galactosamine were noted in both sample I and sample II, but it was not recognizable statistically. The inhibitory effects on the serum LDH activities in protective liver of guinea pigs induced by d-galactosamine were noted in sample II, but it was not noted in sample I group. Conclusion : According to the above results, it is considered that Jucha-whan has treatment effects on liver injury in guinea pigs induced by $CCl_4$ and d-galactosamine. So it is required to study about the actions of mutual relation of medicines and patho-mechanism through experiment.

Background and Objectives: The Objective of this study was to compare the effectiveness of the needle aspiration method and the I&D method in the treatment of peritonsillar abscess. Materials and Methods: A prospective clinical study was performed on 83 patients. All the patients were hospitalized after random treatment with either I&D or needle aspiration alone, received the same intravenous antibiotic therapy. Among the 83 patients, 73 patients who could be observed for longer than 6 months and had not undergone a tonsillectomy during the follow-up period, were analyzed for treatment outcomes. Results: There was no statistically significant difference in the initial failure rate(p=0.572), the hospitalized days(p=0.956), the recurrence rate(p=0.531) for the needle aspiration(35 patients) and I&D groups(38 patients). But, The mean duration of fever were statistically different in the needle aspiration(1.51 hours) and I&D groups(3.05 hours) (p=0.031). Conclusion: Two methods are thought to be similar in effectiveness, except that duration of fever was longer in the I&D group than in the needle aspiration group. However, taking advantages of the needle aspiration method into consideration, the needle aspiration of peritonsillar abscess may be more appropriate than I&D as an initial method for peritonsillar abscess

A MMIC (Monolithic Microwave Integrated Circuit) mixer chip using the Schottky diode of an GaAs p-HEMT process has been developed for the I/Q demodulator of non-contact near field microwave probing system. A single balanced mixer type is adopted to achieve simple structure of the I/Q demodulator. A quadrature hybrid coupler and a quarter wavelength transmission line for 180 degree hybrid are realized with lumped elements of MIM capacitor and spiral inductor to reduce the mixer chip size. According to the on-wafer measurement, this MMIC mixer covers RF and LO frequencies of 1650MHz to 2050MHz with flat conversion loss. The MMIC mixer with miniature size of $2.5mm{\times}1.7mm$ demonstrates conversion loss below 12dB for both variations of RF and LO frequencies, LO-to-IF isolation above 43dB and RF-to-IF isolation above 23dB, respectively.
