This study examined the effect of dietary salt levels on the incidence and cure of gastric ulcer in rats. Two sets of experiment were conducted . In the first experiment, the rats were divided into 3 groups. The 3 groups were fed 0%, 4%, and 8% NaCl diets respectively for 20days. The rats were given water -immersion restraint stress at the end of the dietary period , and sacrificed. The ulcer index by histological test was higher in rats fed the 8% NaCl diet than those in the other groups. The hexosamine and glutathione levels were significantly lower in the rats fed the 8% NaCl diet. Hematocrit and total iron binding capacity(TIBC) showed lower values caused by bleeding of gastric mucosa. The second experiment was designed to determine the effect of soldium concentration on the cure of gastric ulcer . As the gastric ulcer was recovered, ulcer length was gradually deceased in the control group but not changed in the 8% NaCl diet group. The gastric hexosamine and hepatic glutathione were increased in the control group but decreased in the 8% NaCl diet group. The hematologic indices of stressed rats showed the same tendency. As a result, dietary salt per se did not cause gastric ulcer . Once an ulcer is formed by stress or any other factor, higher levels of dietary salt may be detrimental to gastric mucosa, thereby delaying the healing of the ulcer. It is recommended that dietary salt intake be reduced in stress-prone people.

Gouty ulcer can be caused by the accumulation of clumps of uric acid in body tissues that lead to acute or chronic inflammation at sites of accumulation. Furthermore, tophi-inhibiting granulation tissue may form a canal that channels microbial infection from the underlying involved joint space, and thus, presents the risk of osteomyelitis development. Accordingly, gouty ulcer must be treated appropriately. In this case, refractory wounds on gouty ulcers at the left shin and left radial ankle were treated by surgical debridement. Negative-pressure wound therapy was used successfully to prevent post-operative delayed wound healing.

In patients with diabetic foot, ulceration and amputation are the most serious consequences and can lead to morbidity and disability. Peripheral arterial sclerosis, peripheral neuropathy, and foot deformities are major causes of foot problems. Foot deformities, following autonomic and motor neuropathy, lead to development of over-pressured focal lesions causing the diabetic foot to be easily injured within the shoe while walking. Wound healing in these patients can be difficult due to impaired phagocytic activity, malnutrition, and ischemia. Correction of deformity or shoe modification to relieve the pressure of over-pressured points is necessary for ulcer management. Application of selective dressings that allow a moist environment following complete debridement of the necrotic tissue is mandatory. In the case of a large soft tissue defect, performance of a wound coverage procedure by either a distant flap operation or a skin graft is necessary. Patients with a Charcot joint should be stabilized and consolidated into a plantigrade foot. The bony prominence of a Charcot foot can be corrected by a bumpectomy in order to prevent ulceration. The most effective management of the diabetic foot is ulcer prevention: controlling blood sugar levels and neuropathic pain, smoking cessation, stretching exercises, frequent examination of the foot, and appropriate education regarding footwear.

Purpose: In a diabetic foot ulcer, superficial fungal infection of the foot may disrupt the skin integrity and provide an avenue for bacterial infection. The prevalence of fungal infection in diabetic foot ulcer has been reported as 12-30% in Caucasian patients. However, no data are available for Korean patients. The purpose of the study was to examine the prevalence of fungal infection in diabetic foot patients admitted in our clinic. Methods: This study included consecutive 30 diabetic foot ulcer patients(24 males and 6 females) admitted from May 2007 to July 2007. The mean age was 60.5 years. All patients underwent mycological examination including direct microscopic examination in KOH and culturing on slants and tubes with Sabouraud's glucose agar. Results: Clinical signs of presumed fungal infection, which were examined by dermatologists, were found in all patients included in this study. Direct microscopic examination was positive for the specimens of the skin and the toenails in 28(93.3%) and 25(83.3%) patients, respectively. In addition, culture result was positive for the specimens of the skin and the toenails in 5(16.73%) and 7(23.3%) patients, respectively. Conclusion: The prevalence of fungal infection in diabetic foot ulcer patients admitted in our clinic is much higher than that in Caucasian patients(83.3-93.3% vs 12-30%).

Purpose: Carcinosarcomas are rare neoplasms in which both malignant epithelial and mesenchymal elements are identified. We have found only twenty one cases of primary cutaneous carcinosarcoma in the English language literature. Therefore it has been difficult to diagnosis because its unclear etiology and low frequency. Methods: A 31-year-old young man with a protruding mass on his ankle dorsum was examined. The tumor was $7{\times}6{\times}3\;cm$ sized and arose from a burn scar. The mass was wide excised and applied split thickness skin graft. Characteristic pathologic finding was a mixture of squamous cell carcinoma and malignant fibrous histiocytoma. Results: Three months after the operation, the patient died of multiple metastasis to the liver, lung and finally of sepsis despite adjuvant chemotherapy and adjuvant radiotherapy. Conclusion: If a metastatic cutaneous carcinosarcoma is diagnosed, wide excision is required. There should be more aggressive management to minimize the risk of recurrence. Further research into the etiology and pathophysiology of the disease and a more careful differential diagnosis may allow improvement in treatment.

Ulcerative colitis, a diffuse inflammatory disease of the mucosal lining of the colon and rectum, is characterized by bloody diarrhea that waxes and wanes without apparent cause. In oriental medicine, Jakyaktang has been used to treat the disease, diagnosed as Damp-Heat dysentery. We prescribed Jakyaktang-gamibang to two patients who had suffered from ulcerative colitis diagnosed as Damp-Heat dysentery. The two patients were treated with Jakyaktang-gamibang and improved in consciousness of symptoms. We suggest that oriental medicine therapy is effective for treatment of ulcerative colitis.

This study was conducted to investigate the repeated dose toxicity of DA-9601, an antiulcer agent of Artemisia app. extract, in rats. DA-9601 was administered orally once a day for 4 weeks to 10 males and 10 females per group at doses of 0(vehicle control), 125, 500 or 2000 mg/kg/day. Throughout the study, no treatment-related deaths and clinical signs were observed. In female rats receiving 125 mg/kg of DA-9601, water consumption increased slightly on day 4, 11 and 25. Hematological examination showed a decrease of MCV and an increase of PLT in male rats at the doses of 500 and 2000 mg/kg groups. Blood biochemistry revealed slight decreases of cholesterol, BUN and Na in male rats and decreases of total bilirubin and creatinine and slight increases of globulin and Cl in female rats. The organ weights at the end of 4 weeks showed slight changes in some organs of treated groups. But, all these changes were not considered to be of toxicological importance, because they did not show dose-response relationship and relevance to gross and microscopic findings. Histopathologically, abnormal treatment-related changes were not observed in any organ and target organs were not detected. On the basis of these results, the NOAEL(no-observed-adverse-effect level) of DA-9601 was estimated to be more than 2000 mg/kg/day under the conditions tested.

Chemical control of bacterial canker of kiwifruit caused by Pseudomonas syringae pv. actinidiae was attempted by spraying of streptomycin sulfate ·oxytetracycline WP streptomycin WP streptomycin ·copper hydroxide WP kasugamycin SL kasugamycin·copper oxychloride WP and copper hydroxide WP. The control efficacies of the bactericides were variable depending upon the spraying schedule,. Application of streptomycin WP and streptomycin sulfate·oxytetracycline WP from middle April to early May was found to be the most effective in controlling the bacterial canker. For copper hydroxide WP the spraying from middle January to early February showed the highest control efficacy. Kasugamycin SL was the most effective in controlling the disease by spraying from middle April to early May but it was still relatibvely effective during other spray periods. Foliar application of copper hydroxide WP and copper-antibiotic formulaions after middle April caused severe phytotoxicity. Kasgamycil SL streptomycin WP streptomycin·copper hydroxide WP and copper hydroxide WP were potential bactericides which could substitute streptomycin sulfate·oxytetracycline WP. Selective applications of the bactericides according to their optimum spray time can enhance the control efficacies against bacterial canker of kiwifruit and retard the emergency of resistant strains of P. syringae pv. actinidiae to the bactericides. The optimum spray number of streptomycin sulfate·oxytetracycline WP was 3 times with 15-day-intervals or 4 times with 10-day-intervals. The result suggested that the potential bactericides to bacterial canker of kiwifruit should be also used according to their optimum spray schedules in order to get their highest control efficacies.

Mass mortality occurred in mud loaches, Misgurnus mizolepis, cultured in ponds located in Kunsan. External signs of affected fish showed hemorrhage of skin and fins, Internally, pale liver with congestion, enlarged kidney, and spleen and enteritis exhibited. Causative bacteria isolated from liver, spleen, and kidney of the disease fish. In biochemical tests, the isolates were similar with those of the reference strains, A. sobria. The aerolysine gene from the present isolate was amplified PCR with the primer SOBF and SOBB for A. sobria. The isolate was identified as A. sobria on the basis of those tests. In virulence test, the present isolate resulted in the development of clinical signs identical to those in naturally infected fish. The present results conclude that the present isolate is A. sobria and can be a pathogen which causes motile aeromonad septicemia to mud loach.

The Overlap syndrome is characterized by a combination of the major hepatobiliary autoimmune diseases such as autoimmune hepatitis, primary biliary cirrhosis and primary sclerosing cholangitis. It is frequently accompanied by inflammatory bowel disease. Chronic lymphoplasmacellular osteomyelitis is characterized by recurrent episodes of bacterial osteomyelitis and is associated with autoimmune diseases (especially inflammatory bowel disease). We report the case of a girl who was diagnosed with ulcerative colitis and autoimmune hepatitis at 4 years of age and with the overlap syndrome with primary sclerosing cholangitis at 6 years. At 9 years, she was diagnosed with chronic lymphoplasmacellular osteomyelitis.
