Pathological study was performed on the 135 cases (137 lesion) of early gastric cancer (EGC) diagnosed during the period from 1970 to 1988. The gastrectomy specimens were obtained from Pusan National University Hospital and Pusan Paik Hospital. The statistical analysis was applied on the point of pathological and epidemiological aspects. The results obtained were summarized as follows: 1) The proportion of patients with EGC of all gastric cancer diagnosed in Pusan area during the period of 1970 to 1974 was 1.3%, those during 1975 to 1979 was 1.7%, those during 1980 to 1984 was 7.8%, and those during 1985 to 1988 was 20.0% respectively. 2) The model age group was 6th decade in both sexes. The average age of patients with EGC was 50. 1-year-old in men and 47. 9-year-old in women respectively. The sex ratio (M/F) was 2 : 1 but it was lower for young people than for old people. 3) The proportion of sites involved by the EGC in the stomach was as follows : the antrum 61%, the body 39%, and the cardia and fundus 0.01%. The intestinal type cancer more frequently involved the lower portion than the upper portion of the stomach. 4) Regarding the distribution of the gross types of EGC, the elevated group (Type I, IIa) accounted for 14%, the flat type (Type IIb) accounted for 4%, and the depressed group (Type IIc, III) accounted for 82%. There was no correlation between the gross type and the depth of the lesion. The elevated group was more frequent in intestinal type than in diffuse type. 5) The size distribution of the EGC was as follows : 46% of the lesions were smaller than 2.0 cm in diameter, 47% were between 2.1 to 5.0 cm, and 7% were larger than 5.1 cm. There was no correlation between the size of the lesion and the gross type. 6) The intestinal type of EGC was 77 lesions (56.2%) and the diffuse type 60 lesions (43.8%). The ratio of both types (I/D) was 1.3 : 1, and it was lower for younger people than for old people. 7) Ten of 135 cases (7%) had lymph node metastases. The metastatic rate of EGC confined to submucosa was much higher than that of EGC confined to mucosa only, but the metastatic rate was not related with the size of the lesion.

Hemangiopericycic maningioma is clinically and pathologically similar to peripheral Hemangiopericytoma and now tends to be terned as hemangiopericytoma of central nervous system. The authors studied 3 cases of hemangiopericytic meningioma obtained from 3 patients, 1 case of meningotheliomatous meningioma, angioblastic meningioma and transitional meningioma, and 2 cases of peripheral hemangiopericytoma, which had operated from November 1988 to May 1989 at the department of neurosurgery, Pusan Inje University Hospital. The authors analysed and compared the immunohistochemical finding and light microscopic apearance. The results obtained were summarized as follows; 1) Classic maningioma (meningotheliomatous meningioma, transitional meningioma and angioblastic meningioma) shows reactivity to both EMA and vimentin. 2) Hemangiopercicytic meningioma and peripheral hemangiopericytoma are reactive only to vimentin, so the two tumors are suggested as same type of tumor. 3) One of 3 cases of hemangiopericytic meningioma shows whorling and interlacing bundles of spindle cells, the peculiar light microscopic features of transitional meningioma, suggesting transitional or mixed form of hemangiopericytic meningioma and transitional meningioma.

Objective: This study aimed to develop texture-modified soups and classify them based on the International Dysphagia Diet Standardization (IDDSI) and National Dysphagia Diet (NDD) criteria. Methods: Ten soups were selected, and a xanthan gum-based thickener was added to adjust their viscosity. Flow tests with a 10 ml syringe and viscosity measurements using a rheometer were carried out according to the IDDSI and NDD criteria. Results: The addition of 1 g of thickener to the selected commercial soups resulted in different viscosity levels depending on the soup type. Under the IDDSI framework, seven soups (R SMG, BMG, KHG, SLT, B SUG, BGG, DGT) were categorized as level 1, two soups (B MYG, ADG) as level 2, and one soup (R DJJ) as level 3. As per NDD guidelines, seven soups (R SMG, BMG, KHG, SLT, B SUG, BGG, DGT) were classified as Nectar-like and three soups (R DJJ, B MYG, ADG) as Honey-like. However, the addition of 2 g of thickener decreased the fluidity of the soups, with two soups (R SMG, SLT) being classified as level 2 and eight soups (R BMG, DJJ, KHG, B SUG, MYG, ADG, BGG, DGT) as level 3 under the IDDSI criteria. Meanwhile, all soups were classified as Honey-like under the NDD criteria. Conclusion The viscosity was different due to the varying compositions of guk/tang/jjigae, the concentration of the thickener, and time. Swallowing standardsands and other guidelines applicable specifically to Korean-food for dysphagia patients need to be developed in a further study.

OBJECTIVE : The sperm acrosome reaction is a Ca2+ -dependent exocytotic event that is triggered by adhesion to the mammalian egg's zona pellucida. Previous studies suggested a role of Ca2+ channels in acrosome reactions. This study was conducted to investigate the T-type calcium channel is operated in acrosome reaction of human spermatozoa. METHOD : Human semen samples were obtained from healthy donors with nomal criteria. The spermatozoa were divided into five groups: Group 1 were non-treated as a control; Group 2 where spermatozoa were exposed to 5 micrometer Ca2+ A23187 (Ca2+i); Group 3 where spermatozoa were exposed 5 micrometer Ca2+i and mibefradil; Group 4 where spermatozoa were exposed 5 micrometer Ca2+i and nifedipine, and Group 5 where spermatozoa were treated with 5 micrometer Ca2+i and both of mibefradil and nifedipine. Spermatozoa in all groups were retrieved after incubation for 15 and 30 minutes at 37degrees C. After staining with PSA-FITC, fluorescence was observed under a fluorescence microscope, and AR was evaluated on a total >100 spermatozoa/side. RESULT AND CONCLUSION : We observed on acrosome reaction inhibition rate in human spermatozoa the various of concentration of mibefradil, nifedipine. Maximum response was noted with 1.0 micrometer mibefradil and the decrease of acrosome reaction inhibition rate 45%. Nifedipine in acrosome reaction inhibition rate was only about 25%. The Ca2+i-induced AR of spermatozoa was significantly suppressed by mibefradil. Incidence of the suppression was depending on concentration of mibefradil. Results from the present study suggest that the human spermatozoa possess T-type channel. The observation that reversible inhibitor of T channels in male germ cells provides a new mechanism of contraceptive action.

Leiomyoma of vagina is relatively rare benign tumor. And majority of these lesions occur in labia major and anterior vaginal wall. The recurrence of this tumor is extremely rare and its cellular atypism, mitotic activity, tumor size and contour are known as important factors in its recutrence. A case of recutrent leiomyoma causing urinary frequency in vesicovaginal septum was reported with a brief review of literature.

Purpose: To retrospectively compare the fixation methods for reattaching a trochanteric fragment in a pertrochanteric fracture treated with bipolar hemiarthroplasty. Materials and methods: Forty cases of an unstable femur pertrochanteric fracture were analyzed and followed up for average of 19(6~40) months. There were 18 cases fixed with tension band wiring (group 1), 7 cases treated using modified tension band wiring with K-wires (group 2) and 15 cases treated with the GTRD (Greater Trochanteric Reattachment Device) (group 3). Result: Group 1 was treated with simple a surgical procedure and the results were good. The second group had firm fixation postoperatively but required additional surgery in two cases to remove the K-wires because of wire migration after ambulation. Group 3 had relatively good results but required more dissection and a longer operating time. Conclusion: Tension band wiring or GTRD are good fixation methods for reattaching trochanteric fragments in pertrochanteric fractures. Moreover, tension band wiring is recommended for old osteoporotic patients due to a simple procedure and firm fixation. The use of modified tension band wiring using K-wire or a Steinmann-pin should not be used due to the possibility of distant migration.
