Hypernephroma comprises about 85-90% of renal malignancy in adults. The natural course of hypernephroma isvery diverse and unpredictable from abrupt explosive growth with wide spread metastasis to asymptomatic slowgrowth for several years. Reports from aliens indicated that hypernephroma with histopathological papillary growthpattern has better prognosis and more frequently hypovascular on renal angiography and less echogenic onultrasonography than non-papillary hypernephroma. Reviewed here retrospectively all the patients who were admittedand diagnosed as hypernephroma histopathologically at the Severance Hospital from March, 1973 through September,1984, in respective of angiographic vascularity, ultrasonographic echogenicity, histopathologic cell type andgrowth pattern, and following results were obtained. 1. The incidence of calcification in hypernephroma was 7cases out of 53 cases(13%). The incidence of hypernephroma according to cell type was clear cell type 20 cases(56%), mixed cell type 11 cases (31%), granular cell type 4 cases (11%), sarcomatous cell type 1 case(2%). Theincidence of hypernephroma according to growth pattern was papillary growth pattern 14 cases(45%) andnon-papillary growth pattern 17 cases(55%). 2. Renal angiographically, hypervascular hypernephroma was 19cases(73%), hypovascular hypernephromas was 6 cases(23%), all of which showed abnormal marginal vessels. 3.Angiographically hypervascular hypernephroma had high incidence of predominantly high echogenicity andangiographically hypervascular hypernephroma had high incidence of predominantly low echogenicity. 4. Clear celltype hypernephroma had high incidence of predominantly low echogenicity on ultrasonography. 5. Predominantly lowechogneic hypernephroma had high incidence of papillary growth pattern and predominantly high echogenichypernephroma had high incidence of non-papillary growth pattern. In summary, clear cell type hypernephroma hadhigh incidence of hypovascularity angiographically and hypovascularity on angiography was correlated withpredominantly low echogenicity on ultrasonography, and predominantly low echognicity had high incidence ofpapillary hypernephroma which was reported to have more good prognosis than non-papillary hypernephroma. So, itcan be suggested that if a hypernephroma show hypovascularity on angiography or predominantly low echogenicity onultrasonography, it has a good prognosis than hypervascular or predominantly high echogenic hypernephroma.

Trachea is lined by a pseudostratified epithelium which usually expresses a complex mixture of stratified as well as simple epithelial-type cytokeratins. In the present work, the cytokeratin expressions was studied immunohistochemically in the tracheal epithelium and gland of human fetus at 14, 26 and 32 weeks of gestation. The primary antibodies used were CK7, 8, 10, 14, 18, AE8, 5D3, MNFl16 and AE3. In PAS-hematoxylin stain, the tracheal eithelium was composed of pseudostratified ciliated columnar type and consisted of surface, intermediate and basal layers regardless of gestational ages. The PAS positive cells, however, were decreased in number in proportion to gestational ages. The tracheal gland was not fully differentiated at 14 weeks of gestation, and had well differentiated secretory portions consisting mucous and serous cells at 26 and 32 weeks of gestation. The mucous cells and luminal border of the duct were positive for PAS stain. The tracheal eithelium showed different immunoreactivity between cartilageous and membranous portions. In general, CK7 and 5D3 were expressed in surface cells, AE8 in intermediate cells, and MNFl16 and AE3 in the cells of all layers. At 14 weeks of gestation, the tracheal epithelium immunoreacted for CK7, AE8, 5D3, MNFl16 and AE3. The premordium of tracheal gland was positive for 5D3, MNFl16 and AE3. The tracheal epithelium at 26 and 32 weeks of gestation showed same staining properties to those at 14 weeks of gestation. The duct cells at 26 weeks of gestation were immunoreactive for CK7, 8, 14, 18, AE8, 5D3, MNFl16 and AE3, and those at 32 weeks of gestation were immunoreactive for CK7, 14, 5D3, MNFl16 and AE3. The acinar cells at 26 and 32 weeks of gestation were positively stained for CK7, 8, 18, 5D3, MNFl16 and AE3. These results suggest that CK7 and 5D3 may serve as useful markers for mature cilated cells, AE8 (CKl3) for immature ciliated cells, and CKl4 for duct cells in tracheal epithelium and gland.

The treatment of supracondylar fracture of the femur remains a difficult problem because of the wide range of portential complications. In the past, authors thought conservative treatment was superior to operative treatment of supracondylar fracture of the femur. In addition, the advent of the Cast-Brace introduced the change in concept of the conservative treatment. Recently, however, the advances in the techniques and in the devices used in intemal fixation have encouraged the operative treatment. Tibiofemoral angle, gap or stepping of the articular surface of the distal femur, range of motion of the knee, and pains in the knee were used to evaluate the following results investigated by statistical study(T-test). These clinical results were shown by analyzing 49 cases of supracondylar fracture of the femur trea ted in the Department of Orthopedic Surgery, Hallym College of Medicine, from Jan. 1980 to Dec. 1983 1. We end result of each patient was evaluated by scaled score value calculated from above mentioned criteria. 2. The mean value of the operative treatment(35 cases) was 31.03±5.52, while that of the conservative treatment(14 cases) was 27.71±4.56. 3. The mean value of the group which began the exercise of the knee joint within 2 weeks (33 cases) was 32.24±4.43. The mean value of the other group which began the exercise of the knee joint after 2 weeks(16 cases) was 25.78±4.56. This difference of means between two groups was statistically significant. Beginning the knee joint exercise within 2 weeks has large effect on the result of the treatment. 4.The results of treatment in patient over age of 50 were graded as fair irrespective of methods of treatment. 5. Various devices were used in intemal fixation but there was no difference in the results. 6. We mean value of the Tibiofemoral angle(difference from normal angle) in the operative treatment was 2.37±6.25 and that of the conservative treatment was 8.04±4.62. Both of the above method of treatment showed a varus trend, especially in the conservative treatment. In statistical study, through, there was no significance in two methods.
