In order to identify the morphological changes of tissues in mouse after irradiation. We have observed the redistribution of LDH isozymes and the morphological changes of skeletal muscle, heart, kidney, liver and testis in mouse according to variation amount with the time after the 1 Gray and 3 Gray irradiation each. As a result of H-E (hematoxylin-eosin) stain, the apoptotic bodies were more easily observed in the liver than the other tissues and the quantity of the apoptotic bodies was proportionated to radiation amount. The number of apoptotic bodies was shown the highest at 1 day in most tissues and at 7 day in testis after irradiation. TUNEL (terminal deoxyribonucleodtidyl transferase-mediated dUTP-digoxigenin nick end labeling) staining was shown the same results as H-E staining. After the irradiation, the protein content was reduced in tissues except kidney. And protein content was reduced in all tissues at the initial period of 2 hours after 3 Gy irradiation. But it increased at 7 days after irradiation. LDH (EC 1.1.1.27, lactate dehydrogenase) activity was increased mostly in tissues at the early stage after 1 Gy irradiation. The maximum activity was detected earlier stage after 1 Gy irradiation than 3 Gy irradiation. The activity of LDH A_4 isozyme was decreased in the skeletal muscle, heart, kidney, and testis. The activity of B-4 and A_2B_2 isozyme was increased in the skeletal muscle and heart, and the activity of heterotetramer isozyme was increase in kidney. The activity of A_4 isozyme in liver was detected high level and the activity of isozyme including subunit C elevated in testis. Therefore, LDH isozyme seems to play a role of lactate oxidase in most tissues except liver after irradiation. These data support that LDH isozyme is predomintly involved in the aerobic metabolism.

Purpose: Recently, we should look for the causes and characteristics of the social problem ``do not ask`` crimes to raise improvement. Methods: This study utilizes the literature and official data and to prepare the concept and characteristics, causes, search for improvements to analysis of domestic and foreign practice of ``do not ask`` crime. Conclusion: ``Do not ask`` criminals is needed the management and protection and it causes a lot lacking in the most vulnerable groups such as home environment and social support in our society. In addition, there is a need to develop a system of social care support help can receive the appropriate early intervention and treatment with mental disorders to the biased thinking and perceptions to impact on ``do not ask`` crimes. Finally, it may appear as extreme anger and hate increase of disadvantaged due to the deepening of socio-economic inequalities. The cooperation in the implementation and protection service agencies will have to be provided community members so that they can move forward with to the establishment of social welfare and criminal policy.

The anterolateral thigh flap was originally described in 1984 as a septocutaneous flap based on the descending branch of the lateral circumflex artery. This flap has some significant advantages for reconstruction of the head and neck. It can be raised as a subcutaneous flap, a fasciocutaneous flap, or a myocutaneous flap and can resurface large defects in the head and neck. In addition, it has a large and long vascular pedicle, and because of the distance of the donor site from the head and neck, it can easily be harvested with a 2-team approach. However, the number and locations of cutaneous perforators vary individually, and thus, it is not widely used because flap elevation is often complicated and time-consuming owing to unexpected anatomical variations. The purposes of this study are to classify the vascular anatomy and to assess the suitability of anterolateral thigh flap for head and neck reconstruction in Korean. We performed an anatomic study on cadavers and analyzed the anatomic pattern of the lateral circumflex femoral arterial system and the perforators nourishing the anterolateral thigh flap. This study suggest the characteristics of vascular anatomic patterns of anterolateral thigh flap of Korean and utility of this flap for head and neck reconstruction.

In performing implant procedures in the anterior portion of the maxilla, many difficulties exist because of anatomical reasons, such as the proximity of the nasal floor, lateral extension of the incisive canal, and labial concavity. On the other hand, in the posterior region of the maxilla, there is often insufficient recipient bone between the maxillary sinus and alveolar ridge due to alveolar ridge resorption and pneumatization of the maxillary sinus. In order to perform implants in such regions, ridge augmentation procedures such as onlay bone graft, guided bone regeneration, and maxillary sinus grafting are performed. In studies of Caucasians, use of autograft from mandibular symphysis has been reported to be highly successful in maxillary sinus grafting. However, in a clinical study of Koreans, autograft of mandibular symphysis has been reported to have significantly low success rate. It has been hypothesized that this is because of insufficient cancellous bone due to thick cortical bone. In order to test this hypothesis, bone quality and morphology of Koreans can be compared with those of Caucasians. In this study, the bone density and morphology of the cortical bone and cancellous bone in the mandibular symphysis of 35 Korean cadavers were evaluated. The following results were obtained: 1. In terms of bone density, type I, type II, and type III consisted of 1.4%(3/213), 72.3%(154/213), and 26.3%(56/213) of the cross-sectioned specimens, respectively. In general, the bone density tended to change from type II to type III, as cross-sectioned specimens were evaluated from the midline to the canine. Type IV wasn't observed in this study. 2. The distance between the root apex and the lower border of the cancellous bone was 18.34mm-20.59mm. Considering that the bone has to be cut 5mm below the root apex during the procedure, autografts with about 15mm of vertical thickness can be obtained. 3. The thickness of cortical bone on the labial side increased from the root apex to the lower border of the mandible. The average values ranged from 1.43mm to 2.36mm. 4. The labio-lingual thickness of cancellous bone ranged from 3.43mm to 6.51mm. The thickness tended to increase from the apex to the lower border of the mandible and decrease around the lower border of cancellous bone. From the above results, the anatomic factors of the mandibular symphysis (bone density, thickness, quantity and length of the cortical bone and cancellous bone) didn't show any difference from Caucasians, and it cannot be viewed as the cause of failure in autografts in the maxillary sinus for implants.
