We are experienced one case of \ulcornerinchu" method operation for chronic thoracic empyema with bronchopleural fistula. A 30-years old male was admitted to our hospital because of right thoracic empyema. In spite of pleural tube drainage, the right entire lung was poorly expanded. The right upper lobectomy and decortication for visceral side of empyema peel were done but expansion of right middle and lower lobe was not enough to fill the pleural space remained Extraperiosteal detachment without performing thoracoplasty was done as the method proposed by Kinchu. The patient recovered without significant problem and the good expansion of remained lung with acceptable pulmonary function was obtained.ined.

After the real birth of vascular surgery occurred with the introduction of the first practical arterial prosthesis about 50 years ago, a variety of potential vascular graft had been tested and rejected. Polytetrafluoroethylene [Teflon, PTFE] was first used as a vascular prosthesis in 1957. Thereafter this pros-thesis was first used clinically in 1972 and has subsequently been widely applied as a small and medium sized vessel replacement because it is easy to use and readily available. There are numerous reports of good results about Polytetrafluoroethylene graft. We experienced the three cases of arterial bypass graft using polytetrafluoroethylene vascular pros-thesis. First, 21 years old female patient had suffered from Takayasus disease which affected the left subclavian artery and right subclavian-left axillary extra anatomical bypass graft as done. Second, 64 years old male patient had suffered from Leriche syndrome for 12 years and the left axillofemoral and femorofemoral extra anatomical bypass graft was done. Third, 34 years old male patient had suffered from recurrent Buergers disease which affected the left popliteal artery and the isolated popliteal artery segment bypass graft was done. Relatively satisfactory result was obtained in early post-operative period in all three cases.

The incidence of syphilitic aortic aneurysm was decreased now a day. The predilection site of cardiovascular syphilis is the thoracic aorta, especially ascending portion. The form of syphilitic aneurysm is characterized by saccular or fusiform. We have experienced 58 year old female complained of intermittent left chest pain for these 2 years. Saccular aneurysm of 7 cm in diameter at the descending thoracic aorta just distal to the left subclavian artery was confirmed with aortogram, and etiologic lesion was suspected as syphilis by her strong positive finding of serum VDRL test. Excision of the aneurysm was done under temporary bypass with heparinized 10mm silicone bypass cannula, and 23 mm Dacron aortic prosthetic graft in 10 cm segment was replaced, and excised aortic segment was confirmed as syphilitic aneurysm on light microscopic examination. Postoperative hospital course was uneventful, and discharged 3 weeks after operation in good normotensive condition. The patient died of CVA 3 months after discharge at home.

Ventricular aneurysm which was first described by John Hunter on 18th century, has been experienced by many surgeons after successful using of cardiopulmonary bypass by Cooley on 1958. According to Gorlin, the definition of ventricular aneyrysm is portion of the ventricle which is not motile at systole (akinesis) or which has paradoxical dilatation at systole(dyskinesis). The ventricular aneurysm is classified to anatomical and functional. The anatomical ventricular aneurysm is devided into true or false again. Average age incidence is ranged from 49 to 60 and male predominance is reported. The cause is ischemic coronary artery disease in almost cases but hypertropoc cardiomyopathy, congenital abscence of myocardium, complication after mitral valvular replacement and trauma may also cause the ventricular aneurysm. Angina pectoris and congestive heart failure are most common clinical manifestations Ventricular tachycardia and systemic embolization are also complained. Using cardiopulmonary bypass, aneurysmectomy alone or combination with coronary artery revasculization are currently done for surgical treatment with steady improvenment of mortality. The first patient was 33 years old man who had true type of ventricular aneurysm on inferior wall the left ventricle near apex with protruded huge organized thrombus. The thromboembolic phenomenon was noted on both lower extremities. Under cardiopulmonary bypass, aneurysmectomy and thrombectomy were done. The aneurysmal orifice was repaired with Teflon buttless suture. The second patient was 30 years old female who had large true type of ventricular aneurysm on inferior wall of the left ventricle. Under cardiopulmonary bypass, aneurysmectomy with repair of aneurysmmal orifice defect by means of double layered Dacron patch was done with reinforce by outer silastic sheet covering. She was discharged from hospoital at post op. 15th day uneventfully.

集合群에서의 元素 抽出에 관한 연구

There are some sets that comprise a large number of elements. Here a trial to sort out every element from each set is given with the expectation that the only element of a random at be left by gradual removing all the other element within each set. We can sort out a random amount of elements from a random set at once. Under such conditions, we can find out the character of groups that can be removed to obtain the above result only by even turns, but make it impossible by odd turns.

曲線운동에 대한 새로운 記述方法

If one point on a curve has a direction of its tangent line, two points on a curve will have two directions different from each other. Thus, the feature of a curve can be described by means of an angle change rate with respect to the distance between points. The unit of an angle change rate for the disdance between two points is defined as 'rad/m', which we call hereafter 'Andi' in brief.

A 21 years old female was admitted our hospital due to repeated pneumothorax. Pneumothrax episode was related to the menstruaction. We diagnosed her case as catamenial pneumothorax. Bullectomy and pleurodesis were done without hormonal therapy. But 2 years later, pneumothorax recurred on same side of the chest. Open thoracotomy was done. And careful searching for endometriotic lesion on pleura and diaphragm was performed but no evidence was obtained. Machanical and chemical pleurodesis were applied, The patient was discharged uneventfully. The patient was taking oral contraceptive medication. OPD follow-up was done without recurrence up to now.

This study was devised to observe the effects of water extracts of the Trichosanthes semen and Sinapsis semen against the growth of some cancer cells in vitro and in vivo. There species of cancer cells, murine lymphoid leukemic cells, L1210, murine lymphocytic cells, P388, and murine ascitic Sarcoma 180 cells, were used for the experiment. The effects of incubation time and concentration of the extracts in the culture medium against the growth of L1210 and P388 cells in vitro were determined. And survival time and results obtained are summarized as follows; 1. The doubling times of the L1210, P388 and Sarcoma 180 cells in culture medium without adding any extracts were 11, 11, and 26 hours, respectively. 2. The growth rates of the L1210 and P388 cells in the culture medium contained the extract of Trichosanthes semen(0.1 ml/5 ml) were 27.3% and 43.6%, respectively, and ED50 values of the both cells were belong to below 0.1 ml of the extract. 3. The growth rates of the L1210 and P388 cells in Sinapsis semen extract were 63.2% to 32.1% and 68.8% to 46.6%, respectively, and ED50 values of the both cells were in the range of 0.1ml to 0.2ml of the extract. 4. The inhibitoy effects of Trichosanthes semen and Sinapsis semen extracts on the growth rate of L1210 and P388 cells in vitro were increased, compared with the control group, by the extention of the incubation time and the increase of concentration of each extract in the culture medium. 5. The numbers of Sarcoma 180 cell ascite of Swiss mice were slightly decreased, compared with control group, by the administration of the both extracts. 6. The survival times of the Swiss mice inoculated with Sarcoma 180 cells were not affected by the administration of the both extracts. According to the above results, it could be said that the water extracts of the Trichosanthes semen and Sinapsis semen were indicated the inhibitory effects on the growth of the L1210 and p388 cells in vitro and in vivo, but the survival time of Swiss mice inoculated with Sarcoma 180 cells could not extended by administration of the both extracts.
