Sarcomatoid renal cell carcinoma is an uncommon tumor that has to be distinguished from renal carcinosarcoma. We have described three cases of sarcomatoid renal cell carcinoma showing different clinical and light microscopic features. An ultrastructural study of the tumor cells from the sarcomatoid area revealed frequent desmosomal junction, confirming the epithelial nature of the neoplasm. All three cases showed an aggressive clinical course and tended to invade adjacent organs or tissues. We believe that an histological and immunohistochemical examination in conjunction with an electron microscopic examination are necessary to diagnose sarcomatoid renal cell carcinoma.

Ten emhalmed cadaveric adult bony hemipelvis specimens were ohtained to evaluate the configuration of the posterior column of acetabulum and to find a safe path for screw placement into it as well as to report on the morphological data of the ischial tuherosity and to determine the most optimaI technique for ischial tuberosity screw placement for open reduction and internal fixation of posterior acetabular fracture. Cadaveric studies were performed analyzing icm cross-sections through the acetabulum for the purpose of studying the anatomical configuration of the danger zone. The plane of the cross-section was perpendicular to the posterior column. Each cross-section had the medial boundary ot the acetabulum projected onto the posterior column. By analysing the projections on the posterior column, the exact configuration of the danger zone was determined. In this study, the average width of the posterior column at the mid-acetabular Ievel was 3.9cm. Computed tomography scan of the acetabulum yielded valuable int'ormation regarding screw placement in the posterior column. The average width, height and depth of the ischial tuberosity were 25.7 mm, 33. 1 mm and 31.7mm, respectively. The average angles hetween the posterior and medial aspects and hetween the posterior and lateral aspects of the ischial tuherosities were 79.5degreesand 111.5degrees, respectively. The entry point of the screw should be Smm or 10mm medial to the lateral margin of the ischial tuherosity and the screws should be directed 35-40degrees, 45-50degrees and 50-55degrees caudally at the level of the inferior acetahular margin and lcm and 2cm below it, respectively. to obtain the most favorable bony purchase.

Closed intramedullary nailing for trochanteric fractures of femur has many advantages such as minimal operative trauma, low incidence of infection, good stability of fracture, low incidence of delayed or nounion and early ambulation. Complications have been frequently experienced especially in elderly, osteoporotic patients, but these could be avoided by meticulous surgical procedure. The authors hsve treated 99 cases of intertrochanteric fracture and 23 cases of subtrochanteric fracture from March 1982 to December 1987 with this method and the results are summerized as follows : 1. The aversge age was 61.4 yrs. 2. In classification of intertrochanteric fracture, stable fractures(Kyle type I & II) were 53 cases(43.3%) and unstable fractures(Kyle type III & IV) were 46 cases(37.6%). And in subtrochanteric fracture, stable transverse fractures were 12 cases(9.8%) and unstable long oblique or spiral fractures were 11 cases(9.0%). 3. Intraoperative complications were experienced in 23 cases(18.8%). The entry hole breakage was most common and occurred in 16 cases. 4. Of the 94 patients with more than 6 months follow-up, 21 patients(22.3%) showed more than one complication, e.g, knee joint pain in 15 cases, external rotation deformity in 8 and nail migration in 11 including 3 cases of fixation loss and one case of nonunion with nail breakage, etc. 5. Complications occurred more frequently in unstable fractures(31.8%) and in old ages (29.1%) than in stable fractures and in young ages respectively. And it was felt that complications could be minimized by packing of the medullary canal with nails. 6. It is thought that flexible intramedullary nailing is a good method for trochanteric fractures of femur not only in elderly debilitated patients but also in young patients. However, experience and caution are required to prevent complications.

OBJECTIVE: To evaluat the effects of a culture medium with glucose in the presence of glutamine on the development of mouse embryos. METHODS: Two-cell embryos recovered from ICR mice at 48 hrs after hCG injection (mated just after hCG injection) were cultured in DMEM (with 20% hFF) supplemented with or without glucose on the presence of glutamine. Embryos were cultured under three different glucose regimens: (1) 0 mM (control); (2) 0.5 mM (group I); or (3) 3.15 mM (group II), and were analyzed at 24, 48, 72 and 96 hours intervals. Chi-square test (x2-test) was used to compare values of groups. RESULTS: No differences were found in the number of embryos showing morula (control: 37.5%; group I: 51.0%; group II: 48.4%), blastocyst (control: 21.5%; group I: 33.3%; group II: 34.4%) and blastocyst and hatching or hatched blastocyst (control: 81.9%; group I: 83.3%; group II: 82.8%) between groups at 24 hrs, 48 hrs or 72 hrs respectively. However at 96 hrs, the number of hatched and attached blastocyst was significantly higher in group I (82.3%) and II (78.5%) than control (63.2%; P<0.05). CONCLUSION: The addition of glucose (0.5 mM) to the DMEM, as energy source, improved the rate of development of late stage embryos in mice.

Thelazia callipaeda was first described by Railliet and Henry in 1910. The first human case was reported by Stuckey in 1917, who extracted four worms in the eye of a coolie in Peiping. In Korea, seven cases of human thelaziasis have been already reported and all of the worms were identified to be thelazia callipaeda. The present paper is to report the 8th human infested case of Thelazia callipaeda in Korea. The patient was 25 years old virgin who had lived in Seoul since birth. She experienced lacrimation and moving foreign body sensation of the left eye, and extracted 1 living worm from the left eye by herself on one day prior to examination. Microscopic measurements of an extracted worm are as follows; A worm(male) is 13.0 mm B worm(male) is 13.1 mm and C worm(female) is 19.0 mm in length. It was confirmed as Thelazia callipaeda Railliet et Henry 1910.

To compare Mono-Test withstandard Mantoux tuberculin test, 221 primary school children aged 6 to 7, were randomly subjected. Each subject was simultaneously ted intradermally with three kinds of tuberculin reagents, 1TU PPD and 5TU PPD at one side of forearm and Mono-Test(Institut Merieux) at other side. Approximately 72 hours later, all sites of tested were measured by author. The criteria for positive Mantoux test was given when the tran sverse diameter of indr ation was 10mm or more. If 2mm or more induration was considreed as positive Mono-test, the sensitivity and specificity of Mono-Test to 1TU PPD Mantiux test were 94.44% and 75.14% respectively, ant those to 5TU PPD Mantoux test were 90.20% and 80.59% respectively. On the other hand, when 5mm or more induration was considered as positive Mono-Test, the sensitivity and specificity to 1TU PPD Mantoux test were 80.56% and 97.30% respectively and those to 5TU PPD Mantoux test were 66.67% and 98.24% respectively. Considering of false negativity and false positivity rates, Mono-Test be used only for screening of tuberculosis instead of Mantoux test and in that case it 4 will be better to using 2mm or more induration as a positive criteria of Mono-Test. Any doubtful or positive Mono-Test case sholud be retested with standard Mantoux test because of its relatively high falsespositive rates.
