Purpose: In hand injury, pedicle is usually damaged by avulsion injury or crushing injury. Because of postoperative pedicle obliteration, it is often hard to save the injured hand and fingers, even after successful replantation. The author introduces three cases of extensive hand injury, and successful results after applicatoin of multiple venous grafts to these patients. Methods: In all cases there was no circulation in any finger. In the first case, some vessels were extracted, so venous graft was applied to two sites of severely damaged venous sites. In the second case, venous grafts were applied to all four digital arteries of all fingers except thumb which got severely crushed, and two sites of dorsal veins. In the third case, venous graft was applied to all four digital arteries of all five fingers, and two sites of dorsal veins and palmar veins each. Results: In all cases, survival of hands and fingers was successful. In the second case, however, amputation in thumb and little finger at DIP joint level was inevitable, because of its severe damage, and the large dorsal defect on index finger was filled with DIEP free flap. Thumb was reconstructed with toe-to-thumb free flap, and additional debulking procedures and contracture release is furtherly needed. In the first case, additional surgery was done, as FDP tendon got re-ruptured, but in long term follow-up, satisfactory range of motion was attained. In the third case, FTSG on dorsal skin region was planned. as flap on dorsal area got partial necrosis. Conclusion: In hand injury, there are many structures to be repaired, but sometimes venous graft is avoided for its long operating time. Even though the length of damaged vessel is enough for anastomosis, the endothelium is often damaged (zone of injury). In extensive hand injury, successful reconstruction would be possible with active venous graft to all vessels suspicious for damage.

A sialocele is a subcutaneous cavity containing saliva, most often caused by facial trauma or iatrogenic complications. In subcondylar fractures, most surgeons are conscious of facial nerve injury; however, they usually pay little attention to the parotid duct injury. We report the case of a 41-year-old man with a sialocele, approximately $5{\times}3cm$ in size, which developed 1 week after subcondylar fracture reduction. The sialocele became progressively enlarged despite conservative management. Computed tomography showed a thin-walled cyst between the body and tail of the parotid gland. Fluid leakage outside the cyst was noted where the skin was thin. Sialography showed a cutting edge of the inferior interlobular major duct before forming the common major duct that seemed to be injured during the subcondylar fracture reduction process. We decided on prompt surgical treatment, and the sialocele was completely excised. A duct from the parotid tail, secreting salivary secretion into the cyst, was ligated. Botulinum toxin was administrated to block the salivary secretion and preventing recurrence. Treatment was successful. In addition, we found that parotid major ducts are enveloped by the deep lobe and extensive dissection during the subcondylar fracture reduction may cause parotid major duct injury.

The researcher has studied the types of accidents and injuries that most often occur to infants, toddlers and preschool children. Using this knowledge, a first aid program was developed for mothers. This researcher used a Quasi experimental study which consisted of a nonequivalent control group pretest - posttest design for injury first-aid knowle. The experimental group consisted of 32 mothers, and the control group consisted of 29. The education program consisted of the types of injury, the structure and function of skin, the methods of obsevation, first-aid awareness, and the standard of professional support in case of contusion, abrasion, laceration, fracture and burn. The education program was developed and based on 'the systemetic design of instruction' by Dick & Carey(1996) and utilized multimedia text book, pictures, examples, practice and discussions to increase understanding and effectiveness of learning. The data for this study was collected from September to early November, 2001. There were two fomative evauations, pretest and posttest with an intervention of education program. The analysis of the collected data was analyzed by descriptive analysis, ANOVA, t-test and paired t-test using the SPSS 10.0 program. The results as follows; 1. The experimental group, who was given an education program before the test, got higher marks on the injury first-aid knowledge than the control group. There was a significant difference in knowledge between experimental group and control group(t=6.578, p=.000). 2. The experimental group got higher marks on the action evaluation than the control group. There were significant differences in the certainity of action (t=8.546, p=.000) and the accuracy of action (t=7.654, p=.000) between experimental group and control group. This study examined how a first aid education program increased effectiveness in the knowledge and action of injury first-aid.

Blunt abdominal trauma may often cause multiple vascular injuries. However, common iliac artery injuries without associated bony injury are very rarely seen in trauma patients. In the present case, a 77-year-old male patient who had no medical history was admitted via the emergency room with blunt abdominal trauma caused by a forklift. At admission, the patient was in shock and had abdominal distension. On abdomino-pelvic computed tomography (CT), the patient was seen to have hemoperitoneum, right common iliac artery thrombosis and left common iliac artery rupture. During surgery, an additional injury to inferior vena cava was confirmed, and a primary repair of the inferior vena cava was successfully performed. However, the bleeding from the left common iliac artery could not be controlled, even with multiple sutures, so the left common iliac artery was ligated. Through an inguinal skin incision, the right common iliac artery thrombosis was removed with a Forgaty catheter and a femoral-to-femoral bypass graft was successfully performed. After the post-operative 13th day, on a follow-up CT angiography, the femoral-to-femoral bypass graft was seen to have good patency, but a right common iliac artery dissection was diagnosed. Thus, a right common iliac artery stent was inserted. Finally, the patient was discharged without complications.

This study is focused on the development of a child human model, which is composed of skin, skeleton, joints and muscle, etc. The dimension of child outer skin is referred to anthropometric data from KRISS (Korea Research Institute of Standards and Science). The positions of joint and mass properties of body segments are calculated from ATB(Articulated Total Body) program, GEBOD. The properties of bones and muscles are obtained by the way of scaling from adult human model. To verify the developed human model, ROM simulation and sled test is conducted. Developed human model can be effectively applied to the evaluation of human injury in crash situation and development of child restraint system. The explicit finite element program $PAM-CRASH^TM$ was used to simulate six-year old child human model.

Keloid disease is a fibroproliferative dermal tumor with an unknown etiology that occurs after a skin injury in genetically susceptible individuals. Increased familial aggregation, a higher prevalence in certain races, parallelism in identical twins, and alteration in gene expression all favor a remarkable genetic contribution to keloid pathology. It seems that the environment triggers the disease in genetically susceptible individuals. Several genes have been implicated in the etiology of keloid disease, but no single gene mutation has thus far been found to be responsible. Therefore, a combination of methods such as association, gene-gene interaction, epigenetics, linkage, gene expression, and protein analysis should be applied to determine keloid etiology.

A 26 year old male patient had admitted to the department of plastic surgery for the treatment of skin defect of forearm and spastic contracture of right hand, attributable to burn injury following carbon monoxide intoxication. After receiving skin graft the patients tenotomy of flexor tendons, the patients was consulted to pain clinic for further evaluation and treatment of allodynia, hyperalgesia, and hyperpathia with marked emotional insufficiency. The patient was treated with stellate ganglion blocks, intermittent or continuous epidural blocks, and intermittent brachial plexus blocks for 3 months. with this treatment the patient's pain level improved to(VAS 10 to 4~5) and was discharged. The patient was readmitted 3 months later, due to the aggrzvation of pain. Brachial plexus blocks were given again by interscalene, supraclavicular, or axillary route, sometimes using a catheter, together with cervical epidural blocks. Tricyclic antidepressant was also prescribed. The results were remarkably good(VAS 2~3) and the patient did not require any further analgesic medication.

Large scalp defects resulting from high-voltage electrical burns require free flaps, preferably skin, to permit optimal coverage and enable future or simultaneous cranial vault reconstruction. The anterolateral thigh permits the harvest of a large area of skin supplied by a reliable perforator. The superficial temporal vessels offer the proximate choice of recipient vessels to enable adequate reach and coverage. The lack of a second vein at this site implies the inability to perform a second venous anastomosis; however, this obstacle can be overcome by using an interposition vein graft, to the neck veins primarily. This assures adequate venous drainage and complete flap survival.

With an aim to disclose causal factors scably grains intoxications, the screening of toxic Fusaria and the detection of toxic priniciples were performed in respect of cultured cells bioassay with HeLa cells, skin-necrotizing effect, histopathological investigation and also chromatographic analysis sith following results ; 1. Among the fungi, Fusarium sp. F-27, F-63 and F-61 were highly toxic to mice, causing liver injury characterized necrosis and inflammation. 2. HeLa cell culture bioassay demonstrated that the cell of the isolated strains of Fusaria were suspected to produce toxic material (Fusarenon-X). 3. The culture filtrates of Fusarium nivale Fn-2B, F-27, and F-63, were injected subcutaneously, and caused inflammation followed by crust on the skin ICR-mice. 4. The observation method of skin-necrotizing effect to the mice can be used to the screening to the toxin-producing fungi isolated from many fusarial contaminations.
