We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

Isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament has been thought very rare. We also had experienced only nine cases of above injury in our center during 5.5 years from January, 1976 to June, 1981. Eight cases of them were followed for an average of the thirteen months, but one of them was eliminated from the study because follow-up study was impossible for the case. The purposes of this paper are to present eight cases of isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament and to discuss the causes and mechanisms of the injury and the method of screw fixation for the avulsed fracture fragment. Seven were injured by traffic accident and one by fall on the knee. All cases seemed to be injured by the force directed against the flexed knee which violently stroke the anterior surface of the proximal end of the tibia or inferior portion of the knee and drove it backwards. We found the tear of posterior capsule only in one patient who was seeming injured by extensive force. All cases were treated operatively by means of screw fixation, and excellent results were obtained in five cases, good in two, and fair in one case.

PURPOSE: c-erbB2 encodes 185 kDa oncoprotein with tyrosine kinase activity and has homology to the epidermal growth factor receptor. c-erbB2 proto-oncogene is found to be overexpressed in approximately 20 to 30% of primary breast cancer and has been associated with poor prognosis and lower response to conventional chemotherapy. MATERIALS AND METHODS: We perfonned a study on 40 infiltrating ductal breast cancers treated with primary surgery and adjuvant chemotherapy. We investigated c-erbB2 expression by immunohistochemistry in paraffin-embedded tissue using polyclonal antipeptide antibody(DAKO). We evaluated the relationships between its expression and the results after over 6 cycles of adjuvant chemotherapy including cyclophosphamide, methotrexate and 5-FU. RESULTS: The median age at diagnosis was 43 years and the median follow-up time was 47.3 months. Thirteen(32.1%) of 40 patients showed the c-erbB2 overexpression in the external domains of protein. There were no correlations among c-erbB2 amplification and other prognostic factors such as hormonal receptors, histologic grade and tumor size. Estrogen receptor and progesterone receptor showed tendency of inverse correlation with c-erbB2 overexpression but it was not statistically significant(p>0.05). c-erbB2 positive patients showed shorter disease free survival compared to c-erbB2 negative patients in univariate analysis(p<0.05)(Kaplan Meire analysis). The patients without c-erbB2 overexpression seemed to survive longer but had no significant survival benefit(p>0.05). CONCLUSION: These findings suggest that overexpression of c-erbB2 may be a marker of poor response to adjuvant chemotherapy with CMF regimen and may be an indicator of more aggressive therapy.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.

6.Retroperitoneal Teratoma: A Report of A Case.
Korean Journal of Urology 1962;3(1):77-80
A case of retroperitoneal teratoma, found in a ten month old female infant was reported. Twenty four hours after the direct retroperitoneal air insufflation, a retrograde pyelography was performed using B.B. 16F. cytoscope. These two studies were essential to make preoperative diagnosis. Review of retroperitoneal tumor was also added.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

The anterior fusion became the popular measure in the treatment of the tuberculosis of the spine. We analysed the 208 cases of the tuberculosis of the spine (174 anterior fusion) who were treated at our department during the period of 1966 to 1973 and compared these results with that obtained during the period of 1957 to 1966. Following has been observed from this comparison. 1. Spine was the most common site in bone and joint tuberculosis (51.7%) but with decreasing tendency. And it was followed by hip, knee, ankle and sacroiliac joints of order. 2. Common age incidence was below 30 years (72.7%) and most common in below 5 years (20.7%). 3. Average duration of disease was 2 years and 2 months. This value was 6 months lower than in previous study. 4. The most common site was changed from lumbar to thoracic vertebrae. 5. The incidence of sinus, cold abscess formation decreased but paraplegia increased in incedence due to high prevalence in thoracic vertebrae. 6. Anterior fusion was performed in 86.1% of the cases. 7. Postoperative complications was found in 17.2%. Adequate rnanagement of chest tube in thoracic areas and blood vessels in lumbosacral areas may be necessary.
