목 적 : 초기 증상이 발열과 경부림프절종대인 Kawasaki병 환아와 경부 림프절염의 임상적 특징을 비교 관찰함으로써 Kawasaki병의 조기 진단과 치료에 도움을 주고자 하였다. 방 법 : 초기 진단이 임상적으로 경부 림프절염, 경부 농양, 비정형성 Kawasaki병 의증 등으로 치료받다 후에 임상적 진단 기준에 의해 Kawasaki병으로 최종 진단된 환아와 경부 림프절염 환아의 후향적 의무기록 조사를 하였다. 결 과 : 발열과 경부 림프절염이 주증상인 Kawasaki병은 일반적 Kawasaki병 보다 좀 더 나이든 환아에서 발생하였으며, 전신적 염증을 시사하는 소견이 더 높게 나타났다. 경부 림프절염 환아들과 비교하였을 시도 전신적 염증을 시사하는 소견이 의미있게 높았다. 경부 림프절염 환아는 항생제 치료 후 0~3.5일(평균 1.4일)내에 임상적 호전을 보였으나, Kawasaki병의 환아들은 항생제에 반응하지 않거나 다른 소견들이 나타나 입원 1~5일(평균 2.9일)에 감마 글로부린을 사용하였으며, 감마 글로부린 사용 후 평균 11.7시간 내에 발열이 소실되었다. Kawasaki병에서 심장에 나타나는 변화는 3례(20%)였으며, 림프절종대 유무와 관계가 없었다. 결 론 : 발열과 경부 림프절종대를 주소로 경부 림프절염 진단 하에 항생제 치료를 받는 환아 중 항생제에 반응하지 않는 경우, Kawasaki병의 검사실적 소견을 보일 때 다른 감염성 질환 외에 Kawasaki병을 꼭 고려해야 한다. Kawasaki병의 다른 임상적 소견들이 나타나는지 주의 깊게 관찰하여, 신속한 진단과 치료를 통해 심장 합병증을 방지하도록 해야 한다.

Deoxynivalenol (DON) is a common food borne mycotoxin and occurs predominantly in grains such as wheat, barley, oats, etc. DON induces systemic health problems such as loss of appetite, emesis and diarrhea in both human and farm animals. Reliable diagnostic parameters for DON intoxication are needed to prevent deep health impact. In order to establish useful diagnostic parameters, we investigated clinical signs, hematological values, serum biochemical values, gross-, histo- and toxico-pathological findings in B6C3F1 male mice after oral administration of DON (0.83, 2.5 and 7.5 mg/kg) for 8 days. Body weight gain was significantly decreased at the highest dose of DON. Anorexia, ataxia, for crudness and lack of vigor were observed at the highest dose DON group. In hematological values, the numbers of WBC and platelets and hemoglobin content were reduced with decreased neutrophil and monocytes by 7.5 mg/kg DON. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were prolonged in a dose-dependent manner and the content of fibrinogen was elevated at high dose of DON. Of serum biochemical values, total protein, globulin, BUN, cholesterol and test-osterone were reduced but total bilirubin and albumin/globulin ratio increased. The enzyme activity of alkaline phosphatase was decreased while that of alanine aminotransferase was elevated. Relative organ weights of thymus, seminal vesicle/prostate and testes were dose-dependently reduced but those of liver and left adrenal gland increased with dose dependency. As for pathological findings, atrophy of thymus, seminal vesicle/prostate and testes and submucosal edema and ulceration in stomach and depletion of lymphocytes in thymus cortex were observed. In conclusion, these clinical, hematological, blood biochemical and patholgical parameters obtained in the present studies can be used for diagnosis of DON-mycotoxicosis, especially, low WBC, platelets, protein, BUN and testosterone and delayed prothrombin time can be available as for reliable diagnostic parameters.

Background and Objective: Atherosclerosis is a diffuse, systemic disease that affects the coronary, cerebral, and peripheral arterial trees. Clopidogrel is widely used antiplatelet agent and its efficacy has been proven in cardiac and extracardiac vascular diseases, but it has several side effects. Therefore we investigated whether Sopunghwalhyeoltang, which is widely used for treating the blood stasis syndrome in traditional medicine, could decrease the side effect of antiplatelets and have a synergic effect. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups, non-treated group (Control group), clopidogrel-treated group (CP group) and clopidogrel with Sopunghwalhyeol-tang treated group (CPS group). The control group was fed with only an atherogenic diet, the CP group an atherogenic diet plus clopidogrel 25mg/kg and the CPS group an atherogenic diet plus clopidogrel 25mg/kg with Sopunghwalhyeol-tang 100 mg/kg. We investigated plasma lipids with liver function test, and performed a histological investigation of liver and abdominal aorta. Results: 1. Photomicrographs of liver and abdominal aorta tissue showed lower histological injury and lipid accumulation in the CP and CPS groups than those in the Control group. 2. In the CPS group, plasma triglyceride level was significantly lower than in the Control and CP groups. 3. In the CPS group, the plasma aspartate aminotransferase (AST) level was significantly lower than in the CP group. Conclusions: The above results shows that a combined treatment of Sopunghwalhyeol-tang and clopidogrel have a synergic effect through inhibiting vessel injury and decrease the side effects of clopidogrel alone.

Many Lactobacillus strains have been promoted as good probiotics for the prevention and treatment of diseases. We engineered recombinant Lactobacillus casei, producing biologically active canine granulocyte macrophage colony stimulating factor (cGM-CSF), and investigated its possibility as a good probiotic agent for dogs. Expression of the cGM-CSF protein in the recombinant Lactobacillus was confirmed by SDS-PAGE and Western blotting methods. For the in vivo study, 18 Beagle puppies of 7 weeks of age were divided into three groups; the control group was fed only on a regular diet and the two treatment groups were fed on a diet supplemented with either $1\times10^9$ colony forming units (CFU)/day of L. casei or L. casei expressing cGM-CSF protein for 7 weeks. Body weight was measured, and fecal and blood samples were collected from the dogs during the experiment for the measurement of hematology, fecal immunoglobulin (Ig)A and IgG, circulating IgA and IgG, and canine corona virus (CCV)-specific IgG. There were no differences in body weights among the groups, but monocyte counts in hematology and serum IgA were higher in the group receiving L. casei expressing cGM-CSF than in the other two groups. After the administration of CCV vaccine, CCV-specific IgG in serum increased more in the group supplemented with L. casei expressing cGM-CSF than the other two groups. This study shows that a dietary L. casei expressing cGM-CSF enhances specific immune functions at both the mucosal and systemic levels in puppies.

This study was performed to investigate of dental plaque, calculus and gingival inflammation in Beagle dogs. Forty adults Beagle dogs (28 male and 12 female) were used in this study. The dogs weighed 9.5 kg and were in good oral and systemic health as determined by physical examination, and all dogs had full and normal dentition. The dogs were given a commercial pellet feed during 2 years period. For all examination procedures, the dogs were premedicated with a subcutaneous injection of atropine sulfate (0.04 mg/kg). Anesthesia was induced and maintained by intravenous administration of ketamine (8 mg/kg) and xylazine (2 mg/kg). Dental plaque, calculus and gingival inflammation were assessed by Logan and Boyce clinical plaque index. Calculi covering the maxillary carnassial and first molar teeth were extensive and were accompanied by severe gingival inflammation and pocket formation. Calculi, accompanied by gingival inflammation, were clearly evident on buccal surfaces of other teeth. Calculi didn't showed on the lingual surfaces, but linguogingival inflammation formed in premolar teeth. Although the general pattern was clear, there was considerable variation among dogs in the rate of deposition of calculus and extend of gingival inflammation. This investigation suggest that feeding of the commercial dry food without dental hygiene increase plaque accumulation and may be a contributing factor in calculi formation and periodontal disease.

Acupuncture as a therapeutic intervention is widely used for the treatment of many functional disorders such as substance abuse and mental dysfunction. Clinical trials are currently underway to determine the effectiveness of acupuncture in the treatment of drug addiction. Yet, there are still many unanswered questions about the basic mechanism of acupuncture. Studies have shown that both the psychomotor stimulant effects and rewarding properties of addictive drugs, including morphine, are sensitized by repeated drug administration and raised the possibility that both of these effects may De linked to the same or closely overlapping the mesolimbic dopamine systems. Neiguan (PC6) point on the pericardium channel which is associated with the brain and its mental function, has been used to treat mental, psychosomatic disorders and gastroenterological disorders. The present study was designed to investigate the effect of acupuncture on repeated morphine-induced changes in extracellular dopamine levels using in vivo microdialysis and to measure the effect of acupuncture on repeated morphine-induced behavioral changes. Male Sprague-Dawley rats were treated twice a day for three days with increasing doses of morphine (10, 20 and 40 mg/kg, s.c.) or with saline. After 15 days of withdrawal, rats were challenged with morphine hydrochloride (5 mg/kg, s.c.). Acupuncture was applied at bilateral Neiguan (PC6) points for 1min after the morphine challenge. Results showed that acupuncture at the specific acupoint PC6, but not at control points (tail and HE8) significantly decreased both dopamine release, behavior induced by a systemic morphine challenge or a single s.c. morphine injection in the morphine-repeated animals. These results suggest that reduction in sensitization may be one mechanism whereby acupuncture alleviates morphine craving in addicts. Moreover, in a more general sense these results suggest that acupuncture can be used as a therapeutic intervention for correcting reversible malfunction of the body by direction of brain pathway and thus acupuncture can contribute to the biochemical balance in the central nervous system by regulating neurotransmitters.

The role of macrophages in the resistance of ICR mice to Candida albicans and Salmonella typhimurium was assessed using silica, agent which selectively inactivates macrophages or poly-2-vinylpyridine-N-oxide(PVNO), a lysosomal stabilizing agent. In addition, effect of silica on humoral and cellular immune responses to sheep red blood cells(SRBC) or polyvinylpyroridone(PVP) was examind. Colonyforming units(CFU) of C. albicans or S. typhimurium in the spleen, livers and kidneys of silica-treated or diluent-treated mice were enumerated at various times after infection. Silica was given i. v. to mice at 4 days or 1 day before infection. Although there was no apparent differences in the number of CFU of C. albicans cultured from the spleens or livers of silica-treated and control mice at every assay period, significant differences in the number of CFU of C. albicans in the kidneys of silica-treated and control mice. Namely, silica given to mice 1 day before infection significantly increased the number of CFU of C. albicans in the kidneys at 2, 4 and 6 days after infection, but did not change the number of CFU at 8 days after infection. Silica given to mice at 4 days before infection significantly increased the number CFU in the kidneys at 2 and 4 days after infection, but rather decreased the number of CFU at 8 days after infection. The number of CFU of C. albians cultured from the kidneys of splenectomized which were experimentally infected mice was similar to the number recovered from sham-operated mice at 4 and 8 days postinfection irrespective of time of infection relative to operation. The pretreatment of mice with PVNO appeared to abrogate the silica-induced susceptibility of mice to C. albicans. PVNO alone showed somewhat protective effect against challenge with C. albicans. In contrast, silica treatment did not alter the number of CFU of S. typhimurium recovered from the spleens and kidneys of mice. The administration of silica to mice at 4 days or 1 day before SRBC immunization significantly suppressed delayed-type hypersensitivity(DTH) reactions to SRBC and antibody production to SRBC, a thymus-dependent antigen and PVP, a thymus-independent antigen. These results provide evidence that macrophages play an important role in susceptibility to Candida infection and strongly demonstrated that macrophages play an essential role in the induction of immune responses in mice.

The purpose of this study was to evaluate the clinical and microbiological outcomes following the use of 30% minocycline-loaded polycaprolacton film and 2% minocycline-loaded gel that was applied locally into pockets combined with scaling and root planing. 25 human subjects who were non-pregnant, non-lactating, aged 20-50 and diagnosed as moderate to advanced adult periodontitis were enrolled. Subjects were excluded if they had a history of severe acute or chronic systemic disease, if they required antibiotic prophylaxis for dental treatment for any reason, or if they reported a history suggestive of hypersensitivity reactions to minocycline or tetracycline. 4quadrants that had several teeth with a 5-8mm probing pocket depth and radiographic evidence of alveolar bone loss for each patient were selected and divided into test sites and control sites according to the split-mouth design. Scaling and root planing was done for each site at baseline(0week). Test sites received the minocycline gel and strip and control sites had saline irrigation. The patients received both treatments simyltaneously. Subgingival irrigation of sterile saline was applied to the control sites for approximately 30 seconds. Minocycline strip and gel was applied into the periodontal pocket at 1, 2, 3, 4 weeks each after scaling and root planing in the test sites. The clinical and microbiological measurements were made at baseline and at the follow-up visits 6, 10, 14, 20 weeks. The results of this study were as follows; 1. The sulcular bleeding index, probing pocket depth and Periocheck test was significantly reduced and the relative proportions of spirochetes and motile rods were significantly reduced and the proportion of cocci was correspondingly increased, in locally delivered minocycline strip group compared to saline irrigation group. 2. In locally delivered minocycline gel group, The effect was the same with minocycline strip group as compared with saline irrigation therapy. 3. There was no significant differences between minocycline strip group and minocycline gelgroup. In conclusion, minocycline HCl local drug delivery combined with scaling and root planing may provide added improvement of clinical and microbiological responses by inhibiting bacterial recolonization of treated sites. It is suggested that the local administration of minocycline-HCl in the periodontal pocket is effective when combined with subgingival mechanical debridement.
