A cross-sectional study was conducted to investigate the effect of long term noise exposure on blood pressure among steel mill workers. The workers participated in periodic medical examinations performed from August 27 to September 6 in 1990. Examined were 1,034 workers with high-level noise exposure(average 91.8+/-5.2 dB{AA)), and 390 workers with low-level noise exposure(average 75.2+/-4.6 dB(A)). No significant difference was found in systolic or diastolic blood pressure between the two exposure groups. Prevalence of hypertension (> or = 160 mmHg systolic or > or = 100 mmHg diastolic) was higher in a younger age group (< or = 40 years old) of high-level noise exposure than of low-level noise exposure. However, the difference was not statistically significant. Furthermore, in younger ages, prevalence of. hypertension appeared to be higher in the hearing loss group (> or = 25dB at 1000 Hz or > or = 40 dB at 4000 Hz in at least one ear) than in the normal hearing group. From multiple regression analysis, hearing loss, body mass index, age, alcohol and family history of hypertension were proven to be predictors of diastolic blood pressure (p<0.02). When regression was performed for each age group, hearing loss was a strong predictor of diastolic pressure in the younger age group (p<0.01).

Wilson disease is a rare genetic disorder of copper metabolism. Although CT findings suggest the disease when CNS pathologic changes are advanced, characteristic brain MR findings are reported to manifest early in the disease. The authors experienced two cases of Wilson disease of the brain and report the MR findings.

We have many unsolved problems about the femoral neck fracture, especially non-union of the fracture and avascular necrosis of the femoral head. It seems clear that underlying these are two basic problems; first, the mechanical difficulties in maintaining secure fixation; and second, biological factors interfering with union, paramount of which is damage to the blood supply of the femoral head. Intra-capsular fracture of the femoral neck heals in the same way as other intra-articular fractures-only by endosteal and not by periosteal repair. If the femoral head has an intact blood supply, repair appears early on both sides of the fracture. But if the femoral head is not viable, this repair appears only on the neck side of the fracture. It can migrate into the head and heal the fracture only if there is close apposition and rigid fixation of well reduced fracture fragments. Clearly the femoral neck fracture heals not by periosteal callus but by callus arising from the marrow supporting structure. Yet there is still no reliable clinical method of determining early the union of the femoral neck fracture and the viability of the femoral head. The femoral head intra-osseous venography, first described by Hulth (1953), to predict viability of the femoral head after fracture of the femoral neck has been carried by various previous authors (Hulth1953 1956 1958, Dahlgren 1959, Harrison 1962, Hulth and Johansson 1962, Nagai 1962). However, they did not mention healing process of fractures of the femoral neck in these studies. To observe the fracture healing and to predict the viability of the femoral head, authors adopted a femoral trochanteric intra-osseous venographic technique. The precedure was carried out under the control of a T-V image intensifier. Venous drainage of the femoral head parallels the arterial supply. There are several venous drainage routes in the hip region; the medial and lateral circumflex vein, gluteal vein, nutrient vein, femoral vein, vein of the ligamentum teres and obturator vein. With the aid of a T-V image intensifier, a bone marrow needle is driven 1 inch below the femoral greater trochanter. When the tip of the needle is in the marrow cavity, about 30cc, of 75% Urograffin is injected. Next X-rays are taken at intervals of 2 seconds, the last film at 5 minutes. A positive venography is one in which venous drainage is seen, and opaque fluid is seen in mottled distribution throughout neck region and part of the head. A negative venography is one in which no venous drainage is seen, on the contrary, opaque fluid pools within the trochanteric region are evident and remain for at least 5 minutes. A positive venography indicates that the head has an intact circulation, thus it may be predicted that the fracture can unite and the head is alive. Negative venography suggests that fracture union is not and will not take place and that the head may be dead. This study provided information about fracture heaIing processes and vascularities of the femoral head and its surrounding tissues during and after fractures healing. We have found that trochanteric intra-osseous venography is a useful diagnostic tool in hip injuries.

The authors reviewed 73 cases of ligament injuries in 70 patients from October, 1972 to June, 1978 who were admitted and treated in the Orthopedic Department at Kyung Hee University Hospital. Of 70 patients, the sex distribution was 59 patients (84%) in male and 11 patients (16%) in female. The high incidence was in age group from 21 to 40 years, that was 46 patients (55%). Traffic accident was most common cause of ligament injuries that was 61 patients (87%). Methods of treatment were direct repair, reconstruction and conservative treatment. Degree of angle and distance were measured with stress radiogram. Degree of angle and distance were also compared with normal and abnormal knee joints. Eleven cases were treated conservatively, and 62 cases, operatively, of whlch direct repair performed in 56 cases and reconstructive surgery, in 6 casea, The summary were as follows: 1. The result was better in the group with conservative treatment, as compared with operative treatment. And conservative treatment was applied only in single ligament injuries. 2. In normal knee joint, degree of angle was distributed evenly in the range of 0° to 10°, and distance was in the range of 0 to 10 mm. 3. In stress radiograrn, the significance of ligament injuries was present in more than 10° and 10 mm. 4. The measurement of distance seemed to be more meaningful than degree of angle. 5. It is helpful to measure the degree of angle and distance in diagnosis of ligament injuries, though not absolute.

OBJECTIVES: To test the hypothesis that the endometrial stromal cells from patients with endometriosis responds differently to the insulin-like growth factor (IGF) compared with those from patients without endometriosis. METHODS: IGFs in peritoneal fluid (PF) from patients with endometriosis(n=18) and without endometriosis(n=12;control patients) were measured by radioimmunoassay. Endometrial stromal cells from patients with endometriosis and control patients were cultured in serum free media(SFM) in the presence or absence of PF or IGF-I(0.25-25 ng/ml) or IGF-II(5-50 ng/ml) and the proliferation of endometrial stromal cells were evaluated by [3H] thymidine incorporation test. All statistics were performed by ANOVA test and student's t-test. RESULTS: When added to SFM, IGF-I(1-25 ng/ml) increased thymidine incorporation in both endometrial stromal cells from patients with endometriosis and control patients in dose dependent manner and IGF-II(5-25 ng/ml) gave similar response in latter cells but not in former cells. Within low IGF-I(less than 100 ng/ml) PF group or high IGF-I(more than 100ng/ml) PF group, the type of endometrial stromal cells did not result in any difference in thymidine incorporation. However, regardless of the source of stromal cells, high IGF-I PF group produced a greater extent of thymidine incorporation than low IGF-I PF group in patients with endometriosis but not in control patients. Also, thymidine incorporation was higher in high IGF-I PF group of former patients than in the same group of latter patients. PF induced higher thymidine incorporation in endometrial stromal cells than the same levels(0.25-2.5 ng/ml) of IGF-I directly added to SFM. CONCLUSIONS: The effects of IGF-I in PF on endometrial stromal cells are similar regardless of their source and IGF-I is one of several growth factors that may participate in the growth of endometrial stromal cells in pelvic endometriosis.
