In the present study, we examined to determine the development of various lymphoid tissue including mucosa-associated lymphoid tissue (MALT), thymus, lymph node and liver. In order to investigate the relationship between the morphological events and the expression pattern of MIC2 antigen (CD99) during the development of lymphoid system, we performed the immunohistochemical study using DN16, a monoclonal antibody against MIC2 (CD99), on formalin-fixed and paraffin-embedded lymphoid sections in 68 human embryos and fetuses, between 5 and 39 gestational week (GW). Four neonates, an infant, and 5 adults are also included. CD99 has been expressed along the membrane of hepatocytes and sinusoidal endothelial cells for 10-28 GW, in when the liver the major site of hematopoiesis. In the thymus, CD99 was firstly detected in the presumptive epitheial cells at 10 GW. When the thymus matured and corticomedullary differentiation appeared, CD99 was exclusively expressed in cortical thymocytes. The CD99 expression in epithelial cells of MALT has initiated at 6 GW and 10 GW earlier than that at the onset of MALT development and its expression has been persisted during MALT formation especially 16-25 GW. The finnding that CD99 antigen was expressed in epithelial cells during the development of MALT rnight provide a means to identify a novel epithelial differentiated substance. In addition, endothelial cells that are present in various organs such as liver and small intestine concurrently expressed CD99 antigen and its expression persisted to late fetal period. This point rnight suggest that CD99 antigen regulate the irnigration of lymphocytes from liver, major hematopoietic organ, to thymus or peripheral lyrnphoid organ via the interaction between endothelial cells and lymphocytes.

6.Effect of Teriparatide on Healing of Atypical Femoral Fractures: A Systemic Review.
Journal of Bone Metabolism 2015;22(4):183-189
BACKGROUND: Bisphosphonates (BPs) are the most commonly used anti-osteoporotic drugs, which have been proven to reduce the risk of osteoporotic fractures. However, use of BPs, particularly for long periods of time, is associated with an increased risk of atypical femoral fracture (AFF). Healing of BP-associated AFF is usually delayed because of suppressed bone turnover. Teriparatide (TPTD), a recombinant form of parathyroid hormone (PTH), enhances bone healing in patients with delayed healing or non-union. METHODS: In this study, we summarized and performed a systemic review of the published literature on treatment of AFF using TPTD. RESULTS: Although there is a lack of level 1 studies on the evidence of TPTD in promoting bone union in AFFs, this systemic review of the available literature revealed that TPTD works positively in AFFs, and we put together the evidence that TPTD is a viable treatment option for enhancing fracture healing in AFFs. CONCLUSIONS: While anecdotal evidence of beneficial effects of TPTD on fracture healing offer limited guidance for clinical decision making, a better understanding of the role of TPTD in fracture healing may be elucidated with future prospective trials.

8.Liver Metastases in Colorectal Cancer.
Journal of the Korean Society of Coloproctology 2009;25(1):63-72
Liver metastases in colorectal cancer are a frequent and lethal complication. Although hepatic resection is an effective treatment for patients with liver metastases in colorectal cancer, only 10-20% of the patients with liver metastases in colorectal cancer are indicated on hepatic resection. However, over the past several decades, liver resection has evolved as a safe and potentially curative treatment for liver metastases in colorectal cancer. Currently the absolute number of patients amenable to resection is large and is growing with better imaging, better surgery, and improvements in systemic therapies to reduce the risk of both intrahepatic and extrahepatic recurrences. The development of active chemotherapy and molecular targeted therapies, together with newer modalities like radiofrequency ablation, have expanded the indications for hepatic resection and improved survival. Also, although initially unresectable, a hepatic resection of colorectal liver metastases after down-sizing by using the above mentioned treatment modalities and chemotherapy can provide a hope for long-term survival that is similar to that of primarily resectable patients. To achieve this objective, for patients with liver metastases, a multidisciplinary team approach has become mandatory, with routine re-evaluation of patients and with adequate timing for each treatment.

PURPOSE: The objective of this study is to evaluate the therapeutic efficacy of ethylenediaminetetraacetic acid (EDTA) chelation and excimer laser phototherapeutic keratectomy (PTK) combined with amniotic membrane transplantation (AMT) for the treatment of band keratopathy (BK). METHODS: Eleven eyes in ten patients with BK received combined PTK (ablation zone of central 7.0-7.5 mm, depth of 50 microm), EDTA chelation (0.05 M, 3 minutes), and amniotic membrane transplantation using fibrin glue. Preand postoperative best corrected visual acuities, symptom changes, reepithelialization time, cosmesis, recurrence, and complications were analyzed. RESULTS: Visual acuity improved in three eyes (27.3%) and did not change in eight eyes (72.7%). Symptoms improved in all patients, and the mean reepithelialization time was 10.6+/-5.3 days. The cosmetic results were good in eight eyes (72.7%) and were fair in three eyes (27.3%). During the mean follow-up period of 11.4+/-6.1 months (range, 6 to 23 months), no postoperative complications or recurrences were observed. CONCLUSIONS: The combination of EDTA chelation, PTK, and AMT is safe and effective for the treatment of band keratopathy.
