  • Objectives : The purpose of this study was to investigate the Correlation between Pelvic angle and the Tibiofemoral angle in the Genu varum. Method : Age of All subjects were 20-37 years. 33(male 10, female 23) subjects were assessed by whole spine x-ray and orthogram. The collected data consisted of items on general characteristics, Pelvic Incidence(PI), Pelvic Tilt(PT), Sacral Slope(SS) and Tibiofemoral Angle(TFA) of the subjects. Results : The PI, PT and TFA had a relationship significantly. However, there was no relationship between SS and TFA. Conclusion : The results suggest that TFA is related to PI, PT. Internal rotation due to genu varum of femoral at hip influence that PI and PT increase.

  • It is thought that highly reactive oxygen radicals generated at the ischemia-reperfusion in case of strokes play an important role in damaging the brain. We examined the neuroprotective effects from the several medicinal herbs in the transient ischemic rat model and compared their effects with the free radical scavenging activities. Transient ischemia was induced by intraluminal occusion of the right middle cerebral artety for 120 min and reperfusion was continued for 22 h in rats. The free radical scavenging properties of medicinal herbs were examined in vitro by determination of the interaction with the 1,l-diphenyl-2-picrylhydrazyl (DPPH) stable free radical. Aqueous extracts of 11 medicinal herbs (200 mg/kg) were orally administered, promptly prior to reperfusion and 2 h after reperfusion. Total infarction volume in the ipsilateral hemisphere of ischemia reperfusion rats was significantly lowered by the treatment of 7 medicinal herbs (Sophora flavescens, Lycopus lucidus, Sanguisorba officinalis, Caesalpinia sappan, Albizia julibrissin, Rubia akane, Psoralea corylifolia, Prunella vulgaris). However, all of these medicinal herbs did not show antioxidative activities. These results suggest that neuroprotective effects of several drugs are not always correlated with their antioxidative properties.

  • Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

  • Experimental studies were undertaken to investigate for the effect of Yijin-tang on the digestive system and isolated uterus of rats. Yijin-tang was composed of five crude drugs; Pinelliae Tuber, Aurantii nobilis Pericarpium, Hoelen, Glycyrrhizae Radix and Zingiberis Rhizoma. The results obtained from experiments with water soluble fraction extracted from Yijin-tang were as follows; Spontaneous motilities of isolated ileum of mice and rabbits were suppressed, and contraction of isolated ileum of mice and guinea-pigs induced acetylcholine, barium chloride and histamine were inhibited. The anticathartic action of mice induced by castor oil were significantly observed. The spontaneous motility of isolated uterus of rats was suppressed. Inhibitory effect of gastric juice secretion and antiulcerogenic action were significantly shown in Shay rats.

  • Basal cell nevus syndrome is inherited as an autosomal dominant trait with variable expressivity. This syndrome comprises a number of abnormalities such as multiple nevoid basal cell carcinomas of the skin, skeletal abnormalities as bifid rib and fusion of vertebrae, central nervous system abnormalities as mental retardation, eye abnormalities, and multiple odontogenic kerato cysts. In 1960, Gorlin and Goltz first described the features of this disease as constituting a true syndrome; since then, it has been realized that it is much more complex and encompassing than initially thought. This patient has many symtoms of basal cell nevus syndrome. - we has known multiple jaw cysts through panorama and facial computed tomography. He has hyperchromatism on basal cell through skin biopsy. In ophthalmologic consult, he has blindness on right. On his past medical history, amputation was done on his toes for polyductalism. - So we report with literature reviews

  • The osteochondroma, also known as osteocartilaginous exostosis, is one of the most common benign tumors of the axial skeleton. These tumours rarely affect the facial skeleton and a true osteochondroma of the mandibular condyle is a very uncommon entity. The tumors are usually slow growing, and symptoms develop over a long time. The most common presentation of the condylar osteochondroma consists of a changing occlusion, the development of facial asymmetry, and a posterior open bite on the affected side. In this case, we treated an osteochondroma of Lt. mandibular condyle through excision of the lesion via the temporal approach to the temporomandibular joint.

  • Objectives : The aim of this study was to review the effect of herbal medicine on hair growth in animal models reported in Korean domestic journals. Methods : Korean core databases were searched with terms alopecia and hair, and animal study reports on hair growth with herbal medicine were reviewed. Animal model, intervention, and hair growth measure data were extracted. Results : A total of 28 reports were reviewed. C57BL/6 mice with depilation was the most frequent animal models used. Polygoni multiflori radix, Cnidii rhizoma and Biotae Folium were frequently used herbal medicine. Positive effects were reported. Conclusions : Herbal medicines may be promising resource for pharmacopuncture materials for positive effects on hair growth.

  • Autogenous bone graft is the useful technique for management of various bone defect in oral and maxillofacial surgery. The most common site for bone graft harvest is the anterior iliac crest. There is usually considerable cancellous bone graft available and it can be obtained with minimal morbidity. However, complications noted in iliac crest grafts include prolonged postoperative pain, hematoma and fracture, gluteal muscle weakness. Occasionally, when large amounts of bone graft are needed and previous harvest procedure had used, iliac bone harvest may be not adequate. Like the iliac crest, the greater trochanter has abundant cancellous bone and is readily accessible with acceptable morbidity. The purpose of this study was to assess the availability of cancellous bone graft from the greater trochanter, compare the quantity with that available from the anterior iliac crest, investigate anatomical hazards, and make recommendations for consistent harvest.

  • The melanotic neuroectodermal tumor of infancy(MNTI) is a rare childhood neoplasm with a clinical presentation. Because of its rapid growth pattern and bone resorption, the lesion can be mistaken for a malignant neoplasm. Although an aggressive growth rate and radiographic appearance, the MNTI almost always behaves in a benign fashion and can be treated with total excision. We presented the MNTI occured in the left maxillary alveolar ridge of 5 month old female infant. showing bluish enlargenent of alveolar mucosa with the displacement of central decidious incisor. And after the surgical excision of the mass, there is no recurrent tendency.

  • We have developed a 2.5-dimensional electromagnetic particle simulation code using the particle-in-cell (PIC) method to investigate electromagnetic phenomena that occur in space plasmas. Our code is based on the leap-frog method and the centered difference method for integration and differentiation of the governing equations. We adopted the relativistic Buneman-Boris method to solve the Lorentz force equation and the Esirkepov method to calculate the current density while maintaining charge conservation. Using the developed code, we performed test simulations for electron two-stream instability and electron temperature anisotropy induced instability with the same initial parameters as used in previously reported studies. The test simulation results are almost identical with those of the previous papers.
