Developmental surface ultrastructure of Macroorchis spinulosus was studied by scanning electron microscopy. One-day-old juvenile fluke was leaf-shaped and bent ventrally. Body surface was covered densely with peg-like spines and with cobblestone-like cytoplasmic processes. Ciliated sensory papillae were concentrated around oral sucker. Several unciliated sensory papillae occurred equidistantly on oral sucker and acetabulum. The ciliated papillae appeared in two longitudinal lines symmetric bilaterally on dorsal surface. On adult flukes, tegumantal spines became wider in middle of the body surface. The cytoplasmic processes differentiated into more fine velvety form. It is likely that the differentiated fine cytoplasmic processes are an increased absorptive surface to adult M. spinulosus. It is suggested that single pointed tegumental spines on anterior half of the body may be supportive for this fluke to migration.

Rhabdomyosarcoma which was first described by Weber has generally been considered asan uncommon tumor. Pack and Eberhart were of the opinion that rhabdomyosarcoma represented 13.9 percent of soft tissue sarcomata. Recently it was classified as four types such as pleomorphic, embryonal, botryoid and alveolar type by many authors. We have experienced two cases of embryonal rhabdomyosarcoma, one arised within left leg and the other within right foot. The former(3 months old, female) showed tumor mass at birth, the latter(13 months old, male) showed at 1 month after birth.

Endoscopic retrograde cholangiopancreatography(ERCP) procedures are more difficult in patients who have undergone partial gastrectomy with Billroth II anastomosis. Because its altered anatomical relationship. the endoscopist is presented with additional problems: (i) Dfficulties in entering the afferent loop, depending on the surgical techiques used. (ii) The endoscope may be too sort to reach the papillary region unless the loops are suecessfully straightened out. (iii) Difficulties in passing the ligament of Treitz, especially in patients with Braun's anastomosis, (iv) Problems in cannulating the papilla and especially the common bile duct from a reversed position. (v) Problems in carrying out a papillotomy in a correct position. We attempted endoscopic sphincterotomy in 3 opatients previously subjected to gastrectomy with needle knife, and succeeded in 2 of them. In the two patients, successful billary drainage was achieved. And one patients with Billroth II gastrectomy, presented with CBD stone and cholangit, was successfully treated with endoscopic stone retriveial. The patient with a Billroth-II operation may unergo endscopic diagnostic as well as therapeutic procedures with a high rate of success, and can be suitable candidates for ERCP and endoscopic sphincterotomy

Local anesthesia for arthroscopic procedure of the knee is an increasinglv popular technique that avoids the use of general anesthesia and the associated risks of respiratory depression, aspiration, and postoperative sedation. Many authors, for example McGinty etc., Martin, Yoshiya etc., advocated local anesthesia as safe and efficient method for arthroscopic procedures of the knee. We performed arthoroscopy of the knee under local anesthesia on 150 patients for diagnostic and operative purposes between January l993 and December l996. The technique of local anesthesia that we used was that 20cc of 0.5%; bupivacaine with I:200,000 epinephrine was injected into superolateral portal of the knee joint and additional 10-20cc ot 1% lidocaine into the arthroscopic portals. Pnevmatic tourniquet wa, not applied in all cases. We analysed the 150 cases and the results were as follows; The diagnostic arthroscopy was performed in 50 cases and the operative arthroscopy was in 100 cases. The duration ot local anethesia was from 4 hours to 12 hours, with an average of 6 hours. In 35 cases arthroscopy was performed as outpatient procedure and average hospital stay excluding other problem was 5 days. No complication related to systemic toxicity by local anesthetics was observed. Conclusively arthroscopy of the knee under local anesthesia is safe and effective procedure to avoid the risks of general anesthesia but patients selection is very important.

A 52-year-old women, suffering from generalized pruritus due to intrahepatic and common hepatic duct stones, was treated with astemizole, 30mg daily. Sixty one days later, convulsions and syncope developed suddenly during hospitalization. She had no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. As another case, a 44-year-old man suffering from pruritus due to liver cirrhosis, was treated with astemizole, 30mg daily. Thirty two days later, palpitations and syncope also developed suddenly during hospitalization. He was diagnosed liver cirrhosis, 3 years ago and there was no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. Administration of astemizole was stopped immediately. The laboratory investigations revealed the normal range of serum potassium, calcium and magnesium in both cases. The ECG finding showed the prolongation of QTc interval, frequent VPCs and intermittent polymorphic drugs. On 1st and 3rd day, after discontinue of astemisole, the ECG abnormalities disappeard. It is suggested that astemizole overdose can induce prolongation of QTc interval and torsade de pointes, especially in the patient with liver disease.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).
