Diabetic foot ulcer is a serious complication which result from long-standing diabetes. Especially, severe infected diabetic foot ulcer results in unwanted lower extremity amputation. The diabetic patient is considered the relative contraindication for microsurgery because of the severe peripheral vascular disease. Recently, microvascular free tissue transfer technique applied to diabetic foot ulcer. It is well known that free tissue transfer provides immediate soft tissue coverage and control of infection. So it is possible that preservation of the lower extremity through free tissue transfer. A retrospective study of diabetic patients who had infected foot ulcer from 1999 to 2000 with foot defects reconstructed with free tissue transfer were reviewed. Thirteen patients were studied with mean follow-up of 12.7 months. There were two deaths during follow-up period. There were two failures after free flap surgery. All eleven survived patients were ambulatory. There was no recurrence of ulcer. No patient need amputation above the ankle joint. We have found that free tissue transfer for infected diabetic foot ulcer is very effective surgical technique. Careful patient selection and regular follow-up is important.

We often have difficulties in the diagnosis of acute abdominal pain in children because they are unable to adequately express the characteristics of their pain. With a good understanding of the etiologies of abdominal pain associated with ages, we should create a diagnostic approach based on the location of the pain. First, we must differentiate the surgical abdomen from the non-surgical acute abdomen. Then, we have to identify whether the pain originating from intestinal obstruction, ulcerative diseases, or hepatobiliary dysfunction. It is important to interview and examine the patient serially until the patient completely improves. These attitudes will reduce the patient's pain caused by delayed diagnosis and unavoidable misdiagnosis. Finally, the new insight for the appropriate use of analgesics against acute abdominal pain in children is now needed by the pediatrician.

Behcet's disease is classically described as featuring recurrent aphthous ulcers in the mouth and genital organs and as having relapsing iritis. Now it is being recognized as a mul tisystem disorder that involves of the skin, gastrointestinal system, cardiovascular system, lung and the central nervous system as well as the joints, blood vessels and urologic systems. Large vessel diseases are unusual but aneurysm may occur in which the pulmonary circulation may give rise to the massive and often fatal hemoptysis. A 29 year-old man who complained of having dyspnea and hemoptysis during six months visited our hospital. He received right bilobectomy for a mass located in the right lower lobe. He underwent right bilobectomy. The final pathologic diagnosis was a pulmonary artery aneurysm which origina ted from the pulmonary artery.

The aim of this study was to evaluate the anti-inlfammatory effects of Glycyrrhiza glabra Linne extract on ulcerative colitis induced by 3% dextran sulfate sodium in mice. The experimental animals were divided into six groups: control(normal), DSS-induced colitis(control), 1 mg/kg, 10 mg/kg, and 100 mg/kg of Glycyrrhiza glabra Linne extract, and 150 mg/kg 5-aminosalicylic acid(5-ASA)(positive control). We evaluated the pathological disease activity index(DAI), change in weight, colon mucosa damage and myeloperoxidase(MPO) in colon mucosa. Treatment with 10 mg/kg and 100 mg/kg of Glycyrrhiza glabra Linne extract led to significant loss of body weight, the decrease of MPO activity and clinical symptoms such as DAI and histological change. In particular, 100 mg/kg Glycyrrhiza glabra Linne extract led to markedly greater improvement than 150 mg/kg 5-ASA treatment. These results suggest that Glycyrrhiza glabra mediated anti-inflammatory action on colorectal sites may be a useful therapeutic approach to ulcerative colitis.

The reconstruction of deep soft tissue defect such as pressure sore has difficult problems. Myocutaneous flaps have been used commonly as the best coverage method for pressure sore. But, they have several drawbacks such as sacrifice of functional muscle, high morbidity of the donor sites and bulkiness at the recipient site. The concepts of perforator flap has recently developed and widely used to overcome these disadvantages. Between March 2005 to July 2006, we have treated 9 patients who had pressure sore using perforator based fasciocutaneous island rotation flap. Preoperative unidirectional Doppler was used in all cases. Mean number of perforator vessels was 3.8 and flap sizes were from $7{\times}5\;cm$ to $14{\times}13\;cm$. Rotation angles of flap were from 90 degree to 180 degree. In all cases, donor sites were closed primarily. All flap survived completely and postoperative complications were wound dehiscence in 1 case, wound infection in 3 cases. The mean postoperative follow up period was 15.7 months and recurrence was not reported. We could decrease donor site morbidity and cover wound sites easily by using flap rotation and get robust blood supply without sacrifice of functional muscle. Fasciocutaneous perforator island rotation flap would be very useful for various pressure sore treatment.

This study aimed to verify the nutritional and curative effects of protein hydrolysate in rats with cysteamine-induced duodenal uncer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intraperitoneally injected twice cysteamine(13mg/100g BW) at intervals of 3h per day. This procedure was repeated 3$\times$at intervals of 3d. Animals fed on 10% casein diet for infection periods. After last injection, 4 kinds of diets(10% casein, 20% casein, 10% casein hydrolysate, 20% casein hydrolysate) were given. Gastric montility, trypsin activity in gastrointestinal content, retention rate of nitrogen, plasma total protein, albumin, amino-N, urinary urea nitrogen, creatinine and hydroxyproline were analyzed for nutritional effects of dietary nitrogen levels(10%, 20%) and sources(casein, casein hydrolysate). In duodenal ulcer rat model, there was no differences between 20% casein diet and 20% casein hydrolysate in the view of severeness of ulcer, gastric emptying rate, serum total protein, serum albumin, plasma $\alpha$-amino-N, UUN, creatinine excretion, GFR, nitrogen retention. On the other hand, rats on 10% casein hydrolysate diet group had more curative effect of the ulcer, higher plasma albumin concentration and nitrogen retention than 10% casein diet group. The casein hydrolysate diet group was lower trypsin activity in small intestinal content than the casein diet group, at both nitrogen levels(10%, 20%). The results suggest that protein hydrolysate be applied in diet therapy for the patients with gastrointestinal ulcer.

An experimental studies were done to investigate the spontaneous movements to the isolated ileum with the liquid extracts of Wahngkigunchunghapleechungtang. Then the effects of isolated ileum, pylorus-ligated and indomethacin-induced ulcer, gastric juice secretion, and transport abilities of the small and large intestine were studied. The following results have been obtained; 1. Wahngkigunchunghapleechungtang showed to have an inhibitory effects on the smooth muscle contraction of the isolated ileum by acetylcholine chloride and barium chloride. 2. Wahngkigunchunghapleechungtang showed to have an inhibitory effect on the contraction of the gastric fundus-strip by acetylcholine chloride and barium chloride. 3. The preventive effects were not recognized on the pylorus-ligated ulcer, by administration of Wahngkigunchunghapleechungtang. 4. The preventive effects were recognized on the indomethacin-induced ulcer by administration of Wahngkigunchunghapleechungtang. 5. The Inhibitory effects on the secretion gastric juice, free & total acidity, and pepsin output were recognized by administration of Wahngkigunchunghapleechungtang. 6. The transport abilities in the small intestine were not recognized by administration of Wahngkigunchunghapleechungtang. 7. The transport abilities in the large intestine were increased by administration of Wahngkigunchunghapleechungtang. According to the above results, it is considered that the experimental effects of Wahngkigunchunghapleechungtang has correspond to the oriental medical literatures.

this study was performed for the purpose of surveying the distribution and characteristics of the Vibrio species in the diseased farm flounders (Paralichthys olivaceus) during the winter season in Korea. Samples were collected along the southern coast in the Sinam, Keoje Island, and Teosu areas from November '90 to Feburary '91. Nine species of Vibrio were identified as V. tubiashii (85 strains), V. damsela (78 strains), V. anguillarum (21 strains), V. compbelli (9 strains), V. fluvialis (9 strain), V. costicola (1 strain), V. alginolyticus (1 strain), V. gazogenes (1 strain), V. marinus (1 strain), and unidentified 3 groups of bacteria (154 strains) which may have related with V. tubiashii were isolated. Eleven kinds of discs (BBL Co.) were used for antibiotic susceptibility test and 116 strains were selected for the experiment. Most bacteria were powerfully inhibited their growth by 4 antibiotics such as cephalothin, chloramphenicol, colistin, and tetracycline, but they were poorly inhibited by 4 antibiotics such as carbenicillin, kanamycin, penicillin G, and streptomycin.

Eupatilin은 급성위궤양 모델인 HCl-EtOH model에서 0.3mg/kg에서 50% 억제하였으며 10mg/kg에서 95% 최대효과를 나타내었고, indomethacin model에서는 0.8mg/kg에서 50% 억제하였으며, 10mg/kg에서 97% 최대억제효과를 나타내었다. Cyclooxygenase-1의 활성은 1.7, 5.8$\mu\textrm{g}$/$m\ell$에서 prostaglandin E$_2$와 prostacyclin의 생성을 각각 2배 촉진시켰으나, cyclooxygenase-2에 대한 활성에는 영향을 주지 않았다. FMLP로 활성화시킨 호중구에 대한 활성은 0.6$\mu\textrm{g}$/kg에서 50% 억제하여 oxygen free radical 소거활성을 나타내었고, 반면 xanthine oxidase 및 iron-dependant lipid peroxidation 활성에 대해서는 78.8, 26.9$\mu\textrm{g}$/$m\ell$에서50% 억제를 보였다. 5-lipooxygenase 활성은 2.1$\mu\textrm{g}$/$m\ell$ 에서 염증매개인자인 leukotriene B$_4$ 생성을 50% 억제하였다. 이상의 결과로부터 애엽추출의 항궤양 효과는 prostaglandin의 생성촉진 및 oxygen free radical 과 leukotriene B4와 같은 공격인자의 생성억제 등의 복합적인 작용에 기인하는 것으로 생각된다.
