Chronic diabetic patients need to sample capillary blood for monitoring and controlling the blood sugar level. Frequent sampling requires to minimize pain during skin puncture. The present study developed mechanisms to minimize pain with effective sampling procedure. which consisted of tapered spring, guiding tunnel, and 30G needle Penetration depth was limited to within 2mm for pain reduction as well as for safety. Simple no-reuse mechanism also prevented the cross-patient and secondary infection possibility. Clinical experiments demonstrated the best convenience and safety with minimal pain in the diabetes, normal, and nursing students groups. Sing1e blood sampling was enough for successful blood sugar test by portable analyzer. The present sing1e use auto-lancet should be of great convenience in frequent capillary blood sampling for the diabetes.

Case of ischemic colitis after enema for bowel cleansing have been rarely reported, but there has been no case report of a patient on modiefied fasting therapy. A 26-year old male patient with obesity admitted Korean medical hospital of Kyung Hee university for losing weight. He is on a special diet called modiefied fasting therapy, only took the fermented herbal drink. At 2nd day, he received an enema for bowel cleansing. A few hours after enema, he had a bloody diarrhea with lower abdominal pain. His colonoscopic and histologic findings presented ischemic colitis. He was advised to fast for two days and couldn't complete his diet program. We suggest 4 possible reasons : Increased intraluminal pressure by enema, vascular spasm caused by room-temperature glycerin solution colder than intraluminal temperature, predisposition to bleeding disturbances by taking selective serotonin reuptake inhibitor(SSRI) for depression history and mucosal injury by osmotic effect of glycerin solution itself. For reducing the risk of bowel cleansing, glycerin enema should be carefully prescribed and practiced concerning the condition of each patient.

A 10-year-old Paint horse was presented with gradual changes in behavior, characterized as stallion-like including aggressiveness towards people and other horse. The abnormal right ovary was detected via transrectal ultrasonography and rectal palpation. A complete blood count and biochemical panel values were within reference ranges. The hormone analysis revealed increased testosterone 46.00 pg/mL and inhibin 0.856 ng/mL, and progesterone concentration consistent with absence of luteal tissue 1.2 ng/mL more than normal values. The purpose of the study reported was to describe a ovariectomy of enlarged ovary by using the diagonal paramedian approach. This method is useful to minimize surgical exposure and hemorrhage. This ovary was confirmed fibroma by histological examination post operation. Behavior problems and the hormone values were alleviated after surgery, and clinical signs of complication were not showed.

Small bowel malignancy consists 1~2 % of overall gastrointestinal tract cancer and leiomyosarcomas of small intestine are 10~20% of small bowel malignancy. Small bowel leiomyosarcomas are rare in incidence and have no specific symptoms, signs or definite radiologic findings, so it is not easy to diagnose at early stage of disease. They are found occasionally by unknown origined gastrointestinal bleeding, abdominal pain, intestinal obstruction, perforation and palpable mass, and diagnosed mostly by operation. Recently annual case reports are increasing trend in Korea. We experienced two cases of small bowel leiomyosarcoma which was diagnosed finally by pathologic findings, so we report them With literatural review.

Objectives: The study investigated the effect of Korean medicine treatment on a hemiplegic patient with conscious and cognitive disorders due to hemorrhagic transformation after interventional reperfusion therapy of anterior circulation infarction. Case presentation: The patient was treated with acupuncture, moxibustion, cupping, and herbal medicine in combination with Western medicine and physical therapy. The effects on clinical symptoms were evaluated using the Manual Muscle Test (MMT), Glasgow Coma Scale (GCS), Korean Mini-Mental State Examination (K-MMSE), Korean Nursing Delirium Screening Scale (Korean Nu-DESC), and Modified Bathel Index (MBI). After the treatment, the MMT grade increased from Gr.0-1 to Gr.0-3, the GCS score increased from 10 to 15, the K-MMSE score increased from 8 to 15, the Korean Nu-DESC score decreased from 3 to 1, night delirium disappeared, and the MBI score increased from 13 to 26. Conclusions: Complex Korean medicine treatments were effective for improving the clinical symptoms of hemorrhagic transformation after interventional reperfusion therapy for anterior circulation infarction in a patient with hemiplegia and conscious and cognitive disorders. However, further studies are needed.

Experimental trials of unilateral lung transplantation in dogs have been attempted and satisfactory results were obtained without any noticeable difficulty in surgical techniques. Fourteen dogs with the body weight of around 25 kg were anesthesized by 20~30 mg/kg of intravenous Entobar,; one was sacrificed to make available blood for use during transplantation for the recipient dog. A mid-sternotomy incision was performed and 20 mg/kg of Prostaglandin E1 was infused through the pulmonary artery and Euro-Collin's(E-C) preservation solution, cooled down to 4$^{\circ}C$, was perfused at the rate of 70cc/kg by a pressure of 30 cmH2O. The heart-lung block was then resected out and promptly immersed in the prepared preservation solution at 4$^{\circ}C$. One lung preserved in the EC solution at 4$^{\circ}C$ was anastomosed to the recipient dog in the order of the pulmonary vein, bronchus then pulmomary artery and the thoracotomy incision was closed after the bleeding control and tube thoracostomy. Then the pneumonectomy in the opposite side was perfomed in the same manner and the tailored lung was transplanted in the order of the pulmonary vein, bronchus, then pulmonary artery. We conclude that in the bilateral sequential lung transplantation, the right lung transplantation should precede to better expose the operative field and to prevent reperfusion injury; also, the cardiopulmonary bypass should be consider for certain appropriate cases.

Objects : Surgical management of the distal anterior cerebral artery(DACA) aneurysms presents several unique problems to surgeons, such as difficulty in early identification of parent arteries, high incidence of rebleeding and premature rupture, and requirement of unfamiliar approach other than conventional frontotemporal craniotomy. Therefore, preoperative anatomical knowledge of anterior interhemispheric fissure and entry point of dissection is prerequisite. Authors utilized a frontobasal approach for DACA aneurysms by using consistent external landmark for guidance to the deep structure. Materials and Methods : From Nov. 1995 to Jun. 1999, a surgical clipping of DACA aneurysms was carried out in 9 patients among a total 131 patients with intracranial aneurysms. In each case, the clinical and aneurysmal features were carefully reviewed through the angiograms, medical records, and intraoperative findings. Results : The incidence of DACA aneurysms was 6.9% from our series. All cases were arisen from juxtacallosal por-tion ; 6 cases from pericallosal-callosomarginal(PC-CM) junction and 3 from pericallosal-frontopolar(PC-FP) junction. Associated vascular anomalies were noted in 3 cases and multiple aneurysms in 3 cases, respectively. The preoperative clinical grades were generally poor. An early surgery was performed in 7 cases and frontobasal interhemispheric approaches in 7 cases. Postoperatively, two patients died of complications ; one delayed ischemic vasospasm and one aspiration pneumonia but remaining patients recovered well. Conclusion : The frontobasal interhemispheric approach was useful for DACA aneurysms in early surgery. Division of superior sagittal sinus(SSS) enabled a minimal retraction of brain on both sides, and prevention of intraoperative rupture was possible. Authors suggest the frontopolar(first frontal bridging) vein as a constant external landmark for approaching the genu of the corpus callosum and juxtacallosal DACA aneurysms.

Background: To avoid the adverse effects of cardiopulmonary bypass and to overcome late vein graft failure we routinely peformed off-pump total arterial coronary revascularization. Material and Method: From July 2000 to August 2001, 104 consecutive patients underwent first elective off-pump total arterial coronary revascularization. Both internal mammary, radial and gastroepiploic arteries were used. Sequential and composite grafts were used to achieve complete revascularization. Perioperative adverse events and postoperative angiograms were analyzed. Result: A total of 252 arterial conduits were used with an average of 2.47 grafts per patient. A total of 326 distal anastomosis were performed with a mean of 3.13 distal anastomosis per patient. Cross over to on-pump occurred in seven patients (6.7%). Of these 4 were due to unstable hemodynamics during lateral or posterior wall stabilization as a result of cardiomegaly and 3 were due to uncontrolled bleeding during dissection of diffusely dimunitive deeply placed intramyocardial coronary arteries. There were no opeartive deaths. Two cases of perioperative myocardial infarction and transient neurologic complications occurred, respectively. Of the 312 distal anastomoses, 308 (98.7%) were compatible with Fitz-Gibboll A or B patency grading. Conclusion: Off-pump total arterial coronary revascularization was technically feasible in most elective cases with satisfactory early results. However, on-pump coronary bypass surgery should be considered in difficult circumstances, such as cardiomegaly or unfavorable anatomy of the target coronary artery.

One hundred and twenty three patients underwent 137 thoracostomies for spontaneous pneumothorax in the department of Thoracic and Cardiovascular Surgery, Gyeongsang National University from January 1987 to December 1994. There were 118 men and 6 women and average age was )2.4 years. The two most common surgical Indications were recurrent pneumothorax and continuous air leakage. Other indications were visible bullae on simple X-ray, previous contralateral pneumothorax, incomplete expansion of the lung, and bilateral pneumothoraces. Methods of thoracotomy were subaxillary thoracotomy in 82 cases, lateral minithoracotomy in 12 cases and posterolateral thoracotomy in 43 cases. Operation time was 63.0 $\pm$ 30.8, 98.3 $\pm$ 37.9, 186.9 $\pm$ 87.9 minutes respectively, and postoperative chest tube keeping time was 5.2 $\pm$ 4.1 days in subaxillary thoracotomy, 6.2 $\pm$ 5.0 days in minithoracotomy and 10.0 $\pm$ 5.8 days in posterolateral thoracotomy Bullae were present mostly at the apex in spontaneous and tuberculous pneumothorax comparred to the cases of chronic obstructive or emphysematous lung disease, where there were no redilection of presence of bullae (p< 0.01). Operative procedures were wedge resection, bullae obliteration and lobectomy. Postoperative complications were continuous air leakage, bleeding, brachial plexus injury, empyema, and wound infection, but all the complications were cured by the time of discharge. There was no mortality.
