From a retrospective study of 366 cases of breast cancer, following results are obtained. 1) Relative incidence of breast cancer is increased during recent 7 years as compared with total female cancer. 2) Invasive ductal carcinoma and invasive ductal carcinoma with a predominant intraductal component (ICPI) account for 78% of total breast cancer, and its ratio shows little variance during recent 7 years and as compared with previous studies. 3) The incidence of invasive lobular carcinoma is increased as compared with 10 years ago, but it seems more likely that the increase is due to difference in diagnostic criteria rather than due to real increase in incidence. 4) The average patients' age of five major histologic types of breast cancer is 47.3 year. The patient's age of invasive ductal carcinoma is highest and that of ICPI is lowest. 5) Outer upper quadrant is the most frequent site of breast cancer. Left side is slightly more frequent than right side. There is little variance among the histologic types in tumor location. 6) The average symptom duration of patients of major types of breast cancer is 8.4 month. It is longest in invasive ductal carcinoma and shortest in ICPI. 7) Invasive lobular carcinoma is largest in tumor size and intraductal carcinoma is smallest, among the major histological types. 8) Intraductal carcinoma is most freqnently accompanied by nipple discharge and Paget's disease. 9) The rate of axillary lymph node metastasis is highest in invasive lobular carcinoma, followed by invasive ductal carcinoma, medullary carcinoma, and ICPI, in order of freqnency. 10) Distant metastasis is to the bone, lung, liver and brain, in order of freqnency. Medullary carcinoma shows the highest rate of distant metastasis. 11) The important prognostic factors of breast cancer are histologic types, status of axillary lymph node metastasis, size of tumor and histologic grade of malignancy. But there is little difference in prognosis between invasive ductal carcinoma and medullary carcinoma.

The stability of the Knowles pinning in the intertrochanteric fractures of the femur was studied to determine which state would best support the load and compared with that of others. Experimental stable and unstable four-part fractures of the intertrochanteric region were produced by manual straight cut in 20 embalmed adult femora. These fracture were stabilized using accurate or inaccurate reduction combined with implant of Knowles pin parallel to calcar femorale or femoral neck. Those specimen were examined for the maximum load supported with the Universal Testing Machine. The results obtained are as follows: 1. Those femora of stable fracture with accurate reduction and Knowles pinning parallel to calcar femorale were failed by load of 140±13kg. 2. Those femora of stable fracture with accurate reduction and Knowles pinning parallel to femoral neck were failed by load of 120±11 kg. 3. Those femora of stable fracture with minimal displacement and Knowles pinning parallel to calcar femorale were failed by load of 110±10.4kg. 4. Those femora of unstable four-part fracture with accurate reduction and Knowles pinning parallel to calcar femorale were failed by 80±9kg.

The most important spinal disorders in childhood are malformations and mass lesions. High-resolution, real-time ultrasonography of the spine enables the differentation of intraand paraspinal structures in a significant way. This examination does not require sedation, does not use radiation, can be performed in the nursery or an incubator and is less expensive than computed tomography or magnetic resonance imaging. The sonographic appearence of the various kinds of spinal dysraphism is demonstrated and illustrated. Based on our preliminary experience spinal sonography appears to be useful in neonates and infants as the first imaging device for differentiation of cmplex malformation and as a screeing method for occult spinal dysraphism.

OBJECTIVE: This study was conducted to examine the effect of vitrification on the survival and in vitro development of mice 1-cell zygotes. METHOD: Effects of exposure to vitrification solution and vitrification, with different concentrations of the cryoprotectant solution, were examined. The 1-cell zygotes were also subjected to a slow freezing- thawing method to compare with vitrification method. Solution composed of ethylene glycol (6.0 M, 5.0 M, 4.0 M) and sucrose (1.0 M) were used as cryopropectant. The experiments employed the method loading the embryos on electron microscope grids. RESULTS: I. The effects of exposure in vitrification solution 1-cell zygotes were non-toxic at all concentrations of the vitrification solution showing the survival rate between 88.1% and 97.5%. Development into 2-cell was more successful in the higher concentrations of the vitrification solution. Therefore, higher concentrations of the vitirification solution do not seem to cause any problems in vitrification procedure. II. The effects of vitrification method 1-cell zygotes showed the survival rate between 78.8% and 92.4%. The lowest and the highest survival rate was observed in the 6.0 M and 4.0 M vitrification solution, respectively. 2-cell development rates varied from 77.6% to 91.3%. Blastocyst development rate was shown highest in 5.0 M and the lowest in 4.0 M solution. Therefore, the highest 2-cell and blastocyst development rate was observed in 5.0 M solution. III. Comparison of vitrification and slow freezing-thawing method on 1-cell zygotes This experiment showed that 1-cell zygotes had the highest survival and development rates in 5.0 M vitrification solution. Vitrified group of 1-cell zygotes, in the 5.0 M vitrification solution, were compared with the group processed in slow freezing-thawing method. The development rate into 2-cell and blastocyst as well as the survival rate were higher in the vitrified group than in the slowly freezed group. CONCLUSION: 1. The results demonstrate that the best cryoprotectant is a 5.0 M vitrification solution for 1-cell zygotes. 2. Vitrification method significantly increases the survival rate of the 1-cell zygote and its development into 2-cell and blastocyst. Equilibration and exposure time during the vitrification was remarkerbly short in this experiment. Total time, from the exposure to vitirification solution to storage in the liquid nitrogen, was taken only 90 seconds. In contrast, the slow freezing-thawing method have taken more than four hours. Taken together, we presume that the overall time used for the procedure contributes to the results as an important parameter. 3. The loading of 1-cell zygotes on the EM grid is technically more simple and takes less time than the straw or cryo vial method.
