The most common surgical repair method for fingertip injuries are replantation, flap coverage, and skin graft. In fingertip injury cases, acellular dermal matrix (ADM) is generally used in a two-stage operation. In the present case, only ADM was used in a 67-year-old male patient with a right fifth fingertip injury. The patient was undergoing chemotherapy after surgery for colon cancer, preventing prolonged hospitalization. In addition, wound healing was likely to be problematic. As a typical surgical method might have been difficult to apply in such a patient, we performed a one-stage operation, using only ADM on the injured area. Postoperative followup for 3 months showed good wound healing. Accordingly, we report a successful treatment outcome using ADM alone for a fingertip injury.

This research was attempted to seek for a positive approach within the framework of physical therapy instead of the drug treatment in the past, with regard to the ischemic brain injury in the early stage. Accordingly, the aim of this research is to observe the change of HSP27 and HSP70, the genes that are expressed in the early stage of brain injury and to investigate the effects of needle electrode electrical stimulation(NEES), upon applying NEES after ischemia. The experimental method is to give rise to global ischemia and apply NEES to 27 SD-Pat rats with the particulars of being eight-week-old, male, around 300g, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 NEES group(n=9), L14 NEES group(n=9), no applied NEES global ischemia(GI) group(n=9), and then observe their changes of HSP27 and HSP70 at the time lapse of 6, 9 hr and 12 hr after ischemia, using immunohistochemistry methods. Upon observing through the immunohistochemistry method, it was noticed that there was a significant difference between the GV20 NEES group and the L14 NEES group as for HSP27 and there were significant differences among all groups as for HSP70(p<.05). Accordingly, it is supposed that the application of NEES after the outbreak of cerebral ischemia delay the apoptosis in the early ischemic part of forebrain or protect neurons against apoptosis.

To evaluate an effect of toluene application to skin on the enhancement of liver damage in $CCl_4$-pretreated rats, toluene (35 mg/$cm^2$) was sequentially applied for 5 days to the skin of liver damaged rats with $CCl_4$ (6 times every other day: 0.1 ml/100 g body weight-50% $CCl_4$ in olive oil) On the basis of the functional and morphological findings in rat liver, appling toluene to the skin in liver damaged animals led to the more enhanced liver damage. In addition, by applying toluene to skin of liver damaged rats, the hepatic cytochrome P450 content was somewhat more increased, but the hepatic benzylalcohol dehydrogenase activity was significantly decreased (P<0.001), whereas benzaldehyde dehydrogenase activity was not statistically changed. In conclusion, the toluene application to skin in liver-damaged rat led to enhancement of liver injury that may be due to the accumulation of toluene metabolite in liver.

Objective:This study aims to devise industrial injury prevention measures by analyzing industrial injury characteristics including the status of industrial injuries, source of industrial injury and accident type in order to prevent aging workers' industrial injuries that account for more than half in the workplaces in agriculture. Background: Continuous migration from farm to city takes place among young people in rural areas in Korea, a traditionally agricultural country due to rapid industrialization and economic development. The aging rate in rural areas in 2013 was 37.3%, about three times higher than the total aging rate of 12.2% in Korea. According to industrial injury statistics of the Ministry of Employment and Labor, the number of industrial injuries in agriculture shows an uptrend and the industrial injuries of aging workers account for more than 50% each year. Method: Of the 2,970 industrial injury cases occurred in the workplaces in agriculture for five years during 2008 and 2012 offered by a national agency related to health and safety, this study analyzed 1,767 industrial injury cases of aging workers. Results: As a result of an analysis on aging workers' industrial injuries by company size in agriculture, 89.8% of the total number of industrial injuries were analyzed to occur in small scale company. According to aging workers' industrial injuries by source of industrial injury and accident type, the outdoor floor and a fall were analyzed to be the highest at 16.5% and 26.1%, respectively. Conclusion: This study analyzed aging workers' industrial injuries by company size, age, job duration, accident severity, gender, nationality, the source of industrial injury and accident type in order to identify industrial injury characteristics in agriculture. Application: The identification of industrial injury characteristics of aging workers in agriculture is judged to be helpful to devising effective measures to prevent industrial injuries.

Pulse diagnosis that distinguishes internal injury from external injury by comparing the left and right of the chon pulse was formed in the process of Naegyoung's pulsation theory of ST9 and LU9 being assimilated into diagnostic method by taking chon pulse. The founder of school of internal injury, I Dong-won, expanded the horizon for this method to be widely used in clinical practice by especially explaining the specific application and theoretical background. According to him, pulse at ST9 which means chon pulse at the left hand, is bigger than the chon pulse at the right hand, it reflects external injury. Bigger "entrance pulse", a chon pulse at the right hand means internal injury. The reason is the left side of the body is a path for Yanggi so it controls the exterior part and the right side of the body is a path for Eumgi to descend so it controls the interior part. Internal injury develops as the spleen and stomach get injured. If the spleen and stomach is damaged essence derived from food cannot ascend to the stomach and will flow back to the lower part. As a result, fire of Eum type formed at the lower part will shoot up to the upper part and manifests external injury-like exterior syndromes. In this case, evidence distinguishing between internal and external injury is the fact that right hand pulse is bigger than the left hand. The important reason for distinguishing between internal and external injury is because when treating external injury caused by excess syndrome, pathogenic Gi should be dispelled. However, treating internal injury cased by deficiency syndrome, requires promoting the primordial Gi.
