Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

The main trend moves towards early excision and skin grafting as treatment for the deep second degree burns and the third degree burns. The ability to excision & skin grafting. This study prospectively evaluated the ability of laser doppler flow measurements obtained within 72 hours after burn injury to predict the depth of burn wounds. A Periflux system 4001 laser doppler flowmetry had been used to measure cutaneous microflow circulation of 100 selected points of burn wounds in 44 admitted patients from March 1993 to February 1994. The mean value of superficial second degree burn checked by laser doppler was 194.6 perfusion unit(PU). The deep second degree burn was 59.7 PU and third degree burn was 5.1 PU. The blood flow of more than 100 PU reliably predicted the superficial second degree burn with 90.2 percents accuracy. The blood flow between 100 PU and 10 PU predict the deep second degree dermal burn with 96.2 percents accuracy. That of less than 10 PU predict the third degree burn with 100 percents accuracy. There was also a significant correlation between initial flow measurements and the depth of burn wounds. We conclude that laser doppler flow measurements performed early after burn injury are useful in predicting the depth of burn wounds. The laser doppler flowmetry has the advantage of being easy to use, noninvasive, provide immediate result for early determination of burn depth. The laser doppler flowmetry is useful in selecting patients for early excision and grafting of burn wounds.

The term of blow-out fracture refers to a fracture of an orbital wall, typically the orbital floor or medial wall. Especially the medial blow-out fracture is difficulty to approach. Transcutaneous approaches could remain postoperative scars and transconjunctival approaches could give bad visual field and technically difficulties in approaching the medial orbital wall. But the medial transconjunctival incision could avoid an external scar, save the operating time, and decrease injuries of surrounding tissue. Authors operated the medial blow-out fractures through the medial transconjunctival approach and porous high-density polyethylene sheet was placed on fracture site for the prevention of relapse of the orbital contents. 30 cases of medial blow-out fractures were treated using the medial transconjunctival incision. All patients were corrected satisfactorily without leaving any visible scar. Thus the medial transconjunctival approach was an effective way to repair medial blow-out fracture.

OBJECTIVE: To investigate the effect of mirror therapy on recovery of upper limb function and strength in subacute hemiplegia after stroke. METHOD: Fourty subacute hemiplegic stroke patients (onset <6 months) were enrolled and randomly assigned to either the mirror therapy (MT, n=19), or control group (n=21). MT group received mirror therapy for 30 minutes after each treatment, additionally with the traditional rehabilitation programs, 5 days per week for 4 weeks; 2 hours or more per day, 3 days or more per week. To measure the outcome, we performed the manual muscle test (MMT), manual function test (MFT) and Jarmar grip strength test. RESULTS: MT group showed significant improvements in MMT, grasp and lateral pinch force of grip strength test (p<0.05), compared to control group. Improvement in MFT was more evident in MT group (p<0.05). CONCLUSION: Mirror therapy can be used as an adjuvant therapeutic technique for improving upper limb function and strength for subacute hemiplegia.

Increase in agricultural production or steel manufacturing during Proto-Three Kingdoms Period enabled ancient people to establish well-organized ancient kingdoms in Korean peninsula. A pottery in which human skeletons were buried, the urn coffin, has been regarded as one of the frequently used burial system in ancient Korean society. Among them, the small-sized urn coffin was thought to be used for reburial of adult skeleton or burial for infants and children. In this report, we showed that the human adult bones were buried in a very unique pattern. Based on anthropological study, the dead person buried in the urn coffin died in his/her 30s; and every bone fragment belonged to human skull without exception. The dead person might be a warrior killed in action because there have been reports on exclusive burial of skull in a small-sized, ancient urn coffin in Japan, that was commonly interpreted as the burial of ancient warrior's heads decapitated during ancient battle, and were reburied in the burial ground. Nevertheless, considering that the cervical bones were not found along with the skull bone fragments, the tell tale sign of decapitation, more future studies are needed to confirm the hypothesis. However, even so, it could not be easily denied that very unique funeral customs: burial of human adult skull in a small-sized urn coffin, prevailed in the ancient Korean societies in certain regions.

PURPOSE: To investigate the effect of cysteamine on mixed peripheral blood mononuclear cells (PBMCs)-chemically injured keratocytes reaction (mixed lymphocyte-keratocyte reaction; MLKR). METHODS: PBMC stimulation assay was performed after keratocytes were chemically injured with 0.05 N NaOH for 60 seconds. MLKR was treated with various concentrations of cysteamine (0-10 mM). Intracellular reactive oxygen species (ROS) formation was measured using the oxidation-sensitive fluorescent probe, 2'7'-dichlorofluorescein diacetate (DCF-DA). Proliferation rate of PBMCs stimulated by NaOH-treated keratocytes and secretion profiles of matrix metalloprotease-9 (MMP-9), transforming growth factor-beta1 (TGF-beta1), interleukin-6 (IL-6), and macrophage migration inhibitory factor (MIF) were determined using the bromodeoxyuridine proliferation assay and enzyme-linked immunosorbent assay, respectively. RESULTS: Proliferation rate of PMBCs was suppressed by cysteamine in a dose-dependent manner (p = 0.019). Fluorescence of DCF-DA decreased depending on cysteamine concentration (p < 0.001). MMP-9, IL-6 and TGF-beta1 levels were suppressed by cysteamine in a dose-dependent manner (p < 0.05), whereas MIF levels increased with cysteamine concentration of 0.5-10 mM (p = 0.008). CONCLUSIONS: These study results indicate that cysteamine induced the ROS-mediated inhibition of inflammatory cytokine release and proliferation of PBMCs stimulated by chemically injured keratocytes. Thus, cysteamine can be used in the treatment of chemical corneal burns.

A 42-year-old man without any signs or symptoms of illness underwent esophagogastroduodenoscopy (EGD) for a routine health check up. On esophagogastroduodenoscopy, multiple small and yellowish mucosal plaques were detected in the mid to distal esophagus. These plagues proved to be ectopic sebaceous glands of the esophagus according to the histologic examination. On the immunohistochemical staining with anti-Keratin 14, the basal cells and the heterotopic sebaceous glands were immunoreactive for keratin 14. The histogenesis of this extremely rare lesion is not completely clear. There have been some reports on ectopic esophagus sebaceous glands combined with esophageal cancer or gastric cancer. However, malignant transformation of the ectopic sebaceous gland itself has not yet been reported on. This case was regularly followed up for 12 months, and no interval change or malignant transformation was found both endoscopically and histologically.

Skeletal remains collected from the archaeological fields must be maintained carefully, for being used in scientific studies on the physical characteristics, health status, and pathological disease of the ancient or medieval human populations. Even if Joseon Dynasty Human Sample Collection might be a good example for such studies, few of bone collections predated the Joseon Age (e.g. Goryeo Dynasty) have been established until now, possibly owing to poor preservation condition of archaeological sites in Korea. In this study, we performed anthropological studies on a few cases of Goryeo skeletons, which have been rarely reported by anthropologists in Korea. Judging from the preservation status of bones found in various types of Goryeo graves (e.g. earthen- or stone-chambered tombs), many cases seem to be cremated in accordance with Buddhist funeral rites. Goryeo bone collections must be constructed with the bones identified in the earthen tombs, which were preserved much perfectly than those of any other types of Goryeo tombs.

The interactions between the tumor microenvironment and tumor cells determine the behavior of the primary tumors. Whether cancer-associated fibroblasts (CAF) have a tumor progressive or a protective role likely depends on the type of tumor cells and the CAF subpopulation. In the present study, we analyzed the prognostic significance of CAF subpopulations in colorectal cancer (CRC). CAF phenotypes were analyzed in 302 CRC patients by using antibodies against podoplanin (PDPN), alpha-smooth muscle actin (alpha-SMA), and S100A4. The relationship between the CAF phenotypes and 11 clinicopathological parameters were evaluated and their prognostic significance was analyzed from the disease-free and overall survival times. We observed that at the tumor invasive front, PDPN CAFs were present in 40% of the cases, and S100A4 or alpha-SMA CAFs were detected in all the cases. PDPN/S100A4 and alpha-SMA/S100A4 dual-stained CAFs were observed in 10% and 40% of the cases, respectively. The PDPN+ CAFs were associated with 6 favorable clinicopathological parameters and prolonged disease-free survival time. The PDPN-/alpha-SMA(high) CAFs were associated with 6 aggressive clinicopathological parameters and tended to exhibit shorter disease-free survival time. On the other hand, the PDPN-/S100A4(high) CAFs were associated with 2 tumor progression parameters, but not with disease prognosis. The PDPN+ CAF phenotype is distinct from the alpha-SMA or S100A4 CAFs in that it is associated with less aggressive tumors and a favorable prognosis, whereas the PDPN-/alpha-SMA(high) or PDPN-/S100A4(high) CAFs are associated with tumor progression in CRC. These findings suggest that CAFs can be a useful prognostic biomarker or potential targets of anti-cancer therapy in CRC.
