  • Objectives: This study was performed to evaluate effects of Sochungryong-tang Extract(SRE) on osteoclast differentiation and bone resorptionin order to find out the possibility for clinical use in preventing and treating osteoporosis. Methods: To evaluate the effect of SRE on osteoclast differentiation, we induced RAW 264. 7 cells to be differentiated to osteoclasts by RANKL (receptor activator of nuclear $factor-{\kappa}B$ ligand). We measured effect on TRAP (Tartrate-resistant acid phosphatase), NFATc, cathepsin K, MMP-9, inflammation related factors, histogenesis factors and bone resorption. Results: SRE decreased osteoclast differentiation, and also decreased expression of bone resorbing factors such as MMP-9, cathepsin K, TRAP, NFATc1, MITF, c-Fos, osteoclast stimulatory transmembrane protein, calcitonin receptor in RANKL-induced osteoclast. SRE also decreased Cyclooxygenase-2, indusible nitric oxide synthase, $TNF-{\alpha}$, which are thought to be related with the inflammatory bone destruction. Conclusion: SRE inhibits osteoclast differentiation and bone resorption. The results indicate that the BHT extract can potentially be applied for preventing and treating osteoporosis.

  • The conventional surgical treatment for deformed foot has always consisted of massive soft tissue releases combined with varying methods of osteotomies and fusions to plantigrade functional foot. But, the resulting feet have often been foreshortened, stiff, and nothing more than a cosmetically acceptable but functionally poor foot. Now the techniques of distraction histogenesis has been given a new tool to apply to the complex foot deformity. We have recently experienced two cases of severe deformed feet and treated with Ilizarov technique. One patient had postcompartmental severe rigid equinocavovarus foot. And the other had traumatic severe rigid metatarsus abductus. The follow up periods were 14 and 28 months respectively. The feet were aesthetically pleasing. So, we believed that the Jlizarov technique is an excellent treating method for severe deformed foot.

  • The concentration of total protein during the metamorphosis of the Indian meal moth, Plodia interpunctella $H\ddot{u}bner$ was measured using micro-Kjeldahl method by Oser(1965). Healthy specimens were chosen as samples at each developmental stages: the 1st instar larva, the 3rd inster larva, final instar larva, pupae 2, 6, 10 days and the adult 1 day. The total protein concentration decreased gradually until the two day pupal stage and increased at the six day pupal stage. In the one day dault stage, the concentration reached a maximum. In conclusion, changes of total protein concentation through the course of the physiological cycle form a U-shaped curve when graphed against the histolysis of larval organs and the histogenesis of adult organs. In view of controlling pest, the U-shaped pattern of physiological activity indicates that control will be the most effective at the time of the most physiological weakness manifested at the two day pupal stage.

  • Malignant small round cell tumor (SRCT) of the thoracopulmonary region appears to originate in the soft tissues of the chest wall or the peripheral lung. A differential diagnosis of poorly differentiated small round cell tumors which include Ewing's sarcoma of bone and soft tissue, embryonal rhabdomyosarcoma, Askin tumor, neuroblastoma, peripheral neuroectodermal tumor, small cell osteogenic sarcoma and Iymphoma are often difficult by light microscopy alone. In recent, by the extensive studies electron microscopic examination, histochemical study, immune-chemical study, cytogenetics and gene analysis, these tumors may be derived from the primitive and pluripotential cells, differentiating into mesenchymal, epithelial and neural features in variable proportions. Treatment for SRCT of thoracopulmonary region is not determined because of massive involvement of the lung, pleura or soft tissues of the chest wall resulted in a dismal outcome despite aggressive surgery, irradiation and chemotherapy.

  • Background: The calcium-binding S100A4 protein is involved in epithelial to mesenchymal transition, oncogenic transformation, angiogenesis, cytoskeletal integrity, mobility and metastasis of cancer cells. This study aimed to clarify the roles of S100A4 in genesis and progression of glioma. Materials and Methods: S100A4 expression was examined by real-time RT-CPR and Western blot in glioma and paired normal brain tissue (n=69), and compared with clinicopathological parameters of tumors. In addition, glioma U251 cells transfected with an S100A4-expressing plasmid were examined for proliferation by MTT, apoptosis by Annexin V-FITC, and migration and invasion with Transwell chambers. Results: Increased S100A4 mRNA expression was found in gliomas, compared with paired non-tumor tissue (p<0.001). Gradual elevation of overexpression of S100A4 was observed with increasing glioma grade (p<0.001). Astrocytoma showed lower S100A4 mRNA expression than oligodendrogliomas, with glioblastomas having highest values (p<0.001). Similar results were obtained for S100A4 protein, a positive link being found between mRNA and protein expression in gliomas (p<0.001). There was higher growth, lower apoptosis, stronger migration and invasion of S100A4 transfectants than control and mock transfected cells (p<0.001). Conclusions: These findings indicate that up-regulated S100A4 expression is positively linked to pathogenesis, progression and histogenesis of glioma by modulating proliferation, apoptosis, migration and invasion.

  • Changes in the protein concentration in the hemolymph and the oxidation of respiratory substrates at various developmental stages in cabbage worm, Pieris rapae Linne were measured using Biuret method and Warburg manometric method, respectively. The results are summarized as follows: 1. The hemolymph protein contentration decreased gradually until the six-day pupa and increased thereafter. In the fifth larval instar the concentration reached a maximum and was about two times the value for the six-day pupa. 2. Endogenous respiration was very high at the prepupal stage, decreasing at two-day pupa, followed by an increase at the late pupal stage. 3. Glucose showed the marked activity throughout the whole stages, and had the striking influence on both the prepupal and adult stages. 4. The changes in protein concentration and the rate of oxygen consumption exhibited a general pattern of U-shaped curve through the process of life cycle according to histogenesis of the adult organ and histolysis of the larval organ.

  • Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, low grade soft tissue neoplasm of an unknown histogenesis. It is characterized by sheets of mitotically inactive oval and pleomorphic cells, mono- and multi-nucleated giant cells, intranuclear cytoplasmic inclusions and prominent clusters of thin-walled ectatic vessels with perivascular hyalinization. We have experienced a 50 years old male patient who had a palpable mass in his right anterior lower chest wall. The mass was excised and it was confirmed as PHAT. He has been well 2 years postoperatively without recurrence.

  • The lymphoid system of the lung represents a complex network of lymphoid tissue and lymphatic vessels. Lymph nodes are normally located in the hila, adjacent to the lobar bronchi and within the lung to the level of the fourth-order bronchi. Clinically apparent intrapulmonary lymph nodes are rare. Although of intrapulmonary lymph node histogenesis is uncertain, They are probably hyperplastic lymphoid nodules related to inhalation of irritant dusts and attendant distortion of local lymphatic vessels. Intrapulmonary lymph nodes are detected as solitary or multiple pulmonary nodules. These nodules are difficult to differentiate from intrapulmonary metastasis by radiologic finding. We experienced a case of intrapulmonary lymph nodes presenting multiple nodules in a 46 years old man, which was confirmed by thoracoscopic biopsy.

  • Malignant fibrous histiocytoma rarely occurs in the jaws. Although the histogenesis of this tumor remains controversal, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. It is common for metastatic foci to appear in lung and regional lymph node. There are variable treatments such as radiotherapy, surgical excision or combination therapy of surgical excision, chemotherapy and radiotherapy. With the review of literatures, the authors report the clinical study of two cases of malignant fibrous histiocytoma of the jaw.
