Fractures of the body of the talus are extremely rare, constituting only about 0.1 percent of all fractures (Coltart 1952). Consequently, the prognostic problems have so far been elucidated only on the basis of few reports in the literature. The authors experienced an unusual type of the shearing fracture of the talar body with total disocation that the talar body was lying upside down in the ankle joint. Satisfactory results were obtained after follow up period of 20 months and some are reporting this case with bibliographic reviews.

Evidence in human studies of the association of long term habitual exercise with bone mineral content (BMC) and bone mineral density (BMD) mostly come from studies done on athletes. The highest BMC and BMD values in young adults have been found in strength and power-training athletes, while endurance activities such as long distance running and swimming seem to be less effective in obtaining peak bone mineral density. To compare the differences in BMD among ballet, Korean traditional dancing and athletics, we examined the BMD of 10 ballerinas, 10 Korean traditional dancers, 12 athletes and 12 volunteers as the control group. All participants were female. The average age were 20.6 years for the ballerinas, 21.2 for the Korean traditional dancers, 20.4 for the athletes and 21.3 for the control group. Average weights were 50.6 kg for the ballerina, 53.7 kg for the Korean traditional dancer, 59.2 kg for the athletes and 53.8 kg for the control group. Average heights were 162.0 cm for the ballerinas, 160.4 cm for the Korean traditional dancers, 162.3 cm for the athletes and 160.5 cm for the control group. There were no significant differences in the BMD values of the proximal femur and the lumbar spine between ballerinas and control group and between Korean traditional dancers and control group (p>0.05). There was, however, a significant increase of BMD in the proximal femur and lumbar spine of the athletes when compared with the control group (p<0.05) After adjusting for difference in body mass index (BMI) we recompared the BMD of ballerinas, Korean traditional dancer and athletes with BMD of control group and found significant higher lumbar spine BMD values in ballerinas, Korean traditional dancers and athletes. In athletes higher BMD levels were also obtained in the proximal femur including the neck, greater trochanter and Wards triangle regions (p<0.05). There was no significant increase of proximal femur BMD levels for Korean traditional dancers (p>0.05). Differences of BMD values between the ballerinas and control group was statistically significant only in femoral neck (p<0.05).

BACKGROUND: Several methods have been developed to measure skin thickness, including the use of the radiography, micrometer screw gauge, Harpenden's caliper, and ultrasound, but there are no reports to measure skin thickness using computed tomography. OBJECTIVE: We measured skin thickness on the CT films retrospectively. This study was to investigaste variations of skin thickness by age, gender, and different sites. METHODS: Skin thickness was measured on the CT films of 562 patients, including 357 males and 205 females who had undergone brain, chest, and abdominal CT in our hospital. Patients with endocrinologic, malignant, or collagen disease and those on antimetabolite or steroid therapy were excluded. Comparisons of histometric and computed tomographic methods weremade in 5 skin tumors and 1 localized lipodystrophy. Results: 1. The measurements of the skin thickness(mean) in examined sites varied from 0.84 to 3.07 milimeters : the posterior part at the level of the chest(aortic arch level) was the thickest and the anterior part at the level of the forehead(aortic arch level) was the thickest and the anterior part at the level of the forehead(frontal sinus level) was the thinnest. 2. Skin thickness in males wal generally thicker than in females : the anterior and lateral part at the level of the forehead(P<0.0001), the posterior part at the level of the bladder(P<0.2) were thicker in males than in females. 3. In each gender, the thickness of the skin increased with age of 40 or 60, and then decreased with age at every level. 4. Skin on posterior parts of the body was thicker than on other parts. 5. Unlike other levels, skin was thicker on the lateral parts than on the anterior parts at the levels of the forehead and bladder. 6. The measured skin thickness in about 7% greater in formalin fixed tissues than on CT films. CONCLUSION; Computed tomographic measurement of the skin thickness in a reliable method in the aquisition of normal values and their individual variations during cutaneous aging. Moreover, this method is useful in evaluating skin tumors and monitoring the response to therapy of inflammatory conditions.

Angiogenesis is an essential requirement for development, progression, and metastasis of malignant tumors. Vascular endothelial growth factor (VEGF) is one of the important angiogenic factors. Recently the role of angiogenesis has been known in premalignant lesions. This study was performed to determine whether the angiogenesis and VEGF expression were increased in association with histological grade of cervical intraepithelial neoplasia (CIN) and to see the relationship between the angiogenesis and VEGF. Immunostainings for factor VIII and VEGF were performed on 52 cases of cervical neoplasia (12 cases of CIN I, 11 cases of CIN II, 15 cases of CIN III, 7 cases of microinvasive squamous cell carcinoma, and 7 cases of invasive carcinoma) and 5 cases of normal cervix. The results showed a significant increase of microvessel count from normal cervix through CIN grades to invasive squamous cell cacinoma. VEGF expression was increased in proportion to the CIN grades. There was no significant correlation between microvessel count and VEGF expression. In conclusion, the tumor angiogenesis is an early event in tumorigenesis of uterine cervix. In addition, no significant relationship between the microvessel count and VEGF expression in CIN suggests the possibility of other growth factors affecting mainly angiogenesis of premalignant lesion of uterine cervix.

The use of a cultured autologous keratinocyte sheet has become a recognized method for the coverage of extensive bums during recent years. The disadvantages of these sheet grafts are a long time-lag until keratinocyte sheets are available, the fragility and difficulty in handling of grafts, an unpredictable take rate and extremely high costs. In this study we investigated the transplantation of cultured keratinocytes as single cells suspended in autologous fibrin glue. In a rat model with standardized full thickness wounds, this new transplantation technique was evaluated and compared directly to the conventional keratinocyte sheet grafting technique. After transplantation, wounds were evaluated for the degree of epithelial coverage, and then microscopic structures were evaluated under light and electron microscopy. The results were as follows: 1) The fibrinogen solution prepared from autologous blood had 12 times more fibrinogen compared to the original blood. 2) After transplantation of cultured keratinocyt-es in fibrin glue, the degree of epithelial coverage was 79% at 2 weeks, which was comparable to 17% for cultured keratinocyte sheet graft 3) Typical basement membrane structures were consistently found at 2 weeks after transplantation of keratinocytes in fibrin glue. 4) Rete ridges were found at 4 weeks after transplantation of keratinocytes in fibrin glue. In conclusion, the transplantation technique of keratinocytes in fibrin glue is available earlier than sheet grafts, it transfers actively proliferating cells and it simplifies the grafting procedure. As well, this technique leads to an earlier epithelial covering and an earlier restoration of the dermo-epidermal junction than sheet grafting.

The authors studied organic brain syndrome, using organic brain syndrome scale of the Diagnostic Interview Schedule for DSM-Ⅲ, in the subjects of 65 males and 231 females at the homes for the aged in the Taegu and Kyong-buk areas. The authors collected the data during the period from June to August, 1986, and applied ANOVA and x²-test in order to compare various psychologic factors in relation to the organic brain syndrome. The results could be summarized as follows: The elderly males (15%) showed high OBS scores of 12 and over, while ninety elderly females (39%) showed the same scores. Among those psychosocial factors, age, education, birth place, occupation, religion, history before institutionalization are significantly related to the OBS scores.
