"Capsaicin, the pungent principle of hot peppers, is a neurotoxin that depletes primary sensory neurons of neuropeptides like tachykinin. The objectives of these experiment was to examine the effects of capsaicin on Salmonel/a typhimurium-induced production of cytokines such as TNF-a, IL-1B, IL-6, IL-10 and IL-12 and on production of nitric oxide in peritoneal macrophages. In addition, the effects of capsaicin on survival rates of S. typhimurium-infected mice and on nuclear transcription factor (NF-kB) activation were also investigated. Mice were pretreated with a single s.c. injection of 100 ug of capsaicin and were infected i.v. with S. typhimurium (5xO5/mouse) in 0.2 ml volume after capsaicin pretreatment. The serum cytokine levels were measured 30, 60, 120, 180 and 240 min after Salmonella infection, using ELISA kits. The activation of NF-B was also examined by gel shift assay in spleens, thymuses and brains of mice that had been pretreated with a single s.c. injection of 100 ug of capsaicin. It was found that Sa/mone/la infection induced the production of TNF-a, IL-1B, IL-6, IL-10 and IL-12, but capsaicin pretreatment inhibited the production of TNF-a, IL-1B, IL-10 and IL-12, but enhanced IL-6 production 120 min after Salmonella infection. Interestingly, the capsaicin pretreatment inhibited the activation of NF-kB in spleens and thymuses. There were no differences in the numbers of bacteria in livers, brains, spleens, kidneys and lungs between capsaicin- pretreated mice and the control animals in applied experimental conditions. Suprisingly, however, capsaicin pretreatment increased both the survival rates of Sa/mone//a-infected mice and production of nitric oxide by peritoneal macrophages compared with capsaicin-untreated control mice. Taken together, these results indicate that the capsaicin-sensitive primary sensory neurons may play an important modulatory role in the production of cytokine, nitric oxide and NF-B activation and the pathogenesis of salmonellosis."

Cardiovascular syphilis is one of the most important complications of tertiary syphilis, although its incidence is decreasing in recent years. Aortitis is the primary manifestation of cardiovascular syphilis, resulting most commonly in aortic aneurysm, aortic regurgitation and coronary artery ostial obstruction. The authors experienced 46-year-ole male with a history of chancre 20 years ago, and several bouts of right chest pain since last year. Serologic tests revealed reactive in VDRL (1:64) and in TPHA test. Chest x-ray, chest CT, echocardiogram and aortogram showed aneurysm of ascending aorta with no evidence of aortic regrugitation of coronary obstruction. Histologic findings of involved aorta revealed "tree bark" appearance in gross, and microscopically adventitial thickening with endarteritis of the vasa vasorum and destruction of elastic tissue of media, showing moth-eaten appearance. The patient was underwent excision of the aneurysm and dacron aortic prosthetic graft was replaced with success.

Satisfactory surgical reconstruction of the external ear and nose is still a major challenge for the plastic surgeon. Therefore, the use of prosthesis in selected cases should be considered as viable alternative. During the period from December, 1995 to January, 1998, 10 patients, including 9 patients of ear defect and 1 patient of nose defect resulting from the resection of recurrent tumor ablation, were reconstructed by using osseointegration and prosthesis. The surgery was performed in two stages. All procedures were performed under local anesthesia and on an outpatient. At the first stage, the fixtures of titanium implant were placed in the mastoid process and maxilla. These implants were then left for 3 months before the second stage takes place, in which the skin penetrating abutments were attached. After 3-4 weeks, the impression of the defect area were taken and the silicone prosthesis was made by Anaplastologist. Two patients had focal infection but healed without problem. One patient had soft tissue infection, then flap was excised and skin graft performed. There was one loss from 20 fixtures, that was 3 years after implantation. We have concluded that osseointegration for reconstruction of the ear and nose defect is simple, soft, reliable method, which is more than autologous reconstruction and provides excellent aesthetic results.

PURPOSE: We investigated if there are some differences in clinical charecteristics of acute epididymitis between child and adult and if ordinary therapeutic regimen based on antibiotics is the most appropriate one. MATERIALS AND METHODS: We reviewed medical records of 64 patients with acute epididymitis retrospectively, who took admission treatment from July, 1996 to June, 1998 at our hospital. These patients were divided into two groups, child and adult group, younger and older than 16 years respectively. The diagnosis of acute epididymitis was made by symptoms, physical examinations, doppler sonography, and/or radionuclide scan. Chronic epididymitis, recurrent epididymitis, patients taken antibiotics before admission, and surgical epididymis were excluded from this study. We investigated the age of the patients, symptoms, symptom duration and signs. Complete blood count, urinalysis, and urine culture were performed. Independent-samples T-test was used for the comparative analysis of the results. RESULTS: Symptoms including scrotal swelling and pain were not different between two groups significantly. Signs including scrotal tenderness, fever, and leucocytosis were not different between two groups significantly. However, there were statistically significant differences between two groups in studies of urine. Pyuria or positive urine culture were 20.8%(5 of 24) in child group and 52.5%(21 of 40) in adult group(p<0.001). CONCLUSIONS: In acute epididymitis, evidences of urinary tract infection were significantly lower in children than in adults. So, although further studies are needed to find out the exact cause of acute epididymitis, at least ordinary therapeutic regimen based on antibiotics would not be the best one for the majority of children without evidence of urinary tract infection.

PURPOSE: Recent studies demonstrated disruption of the circadian clock gene is associated with the development of obesity and metabolic syndrome. Obesity is often caused by the high calorie intake, In addition, the chronic stress tends to contribute to the increased risk for obesity. To evaluate the molecular mechanisms, we examined the expression of circadian clock genes in high fat diet-induced mice models with the chronic stress. METHODS: C57BL/6J mice were fed with a 45% or 60% high fat diet for 8 weeks. Daily immobilization stress was applied to mice fed with a 45% high fat for 16 weeks. We compared body weight, food consumption, hormone levels and metabolic variables in blood. mRNA expression levels of metabolic and circadian clock genes in both fat and liver were determined by quantitative RT-PCR. RESULTS: The higher fat content induced more severe hyperglycemia, hyperlipidemia and hyperinsulinemia, and these results correlated with their relevant gene expressions in fat and liver tissues. Chronic stress had only minimal effects on metabolic variables, but it altered the expression patterns of metabolic and circadian clock genes. These results suggest that the fat metabolism regulates the function of the circadian clock genes in peripheral tissues, and stress hormones may contribute to its regulation.
