  • Background : An immunochromatographic assay (ICT Diagnostics) which facilitates the diagnosis of tuberculosis(TB) by detecting serum antibodies mainly directed against specific 38KDa of Mycobacterium tuberculosis has come into the market. The test consists of a cardboard folding device containing nitrocellulose strip and absorbent pads. The whole procedure is completed within 15 min and does not require any additional equipment. The test has been reported to be sensitive and specific in diagnosing active TB. Thus the test had been evaluated with sera from TB patients and TB-free subjects. Method : Sera from patients with active pulmonary tuberculosis(40 sputum positives for Mycobacterium tuberculosis, 79 sputum negatives, and 3 extrapulmonary tuberculosis) were obtained from the Double-Cross Chest Clinic of the Korean National Tuberculosis Association (KNTA) in Seoul. The control group consisted of TB-free 68 subjects(21 children under 7 years old and 47 healthy staff members of KNTA). Results : Nine out of 68(13.2%) TB-free controls had positive antibody response. Total 106 of 122(86.9%) radiologically active patients had positive antibodies while 16 (13.1%) showed negative reaction. Antibody was detected in 38 of 40(95.0%) sputum positive patients and 68 of 82(82.9%) sputum negative patients who were under the antituberculosis chemotherapy. The sensitivity and specificity were all 87% and the positive predictive value was 92.2% while the negative predictive value was 78.7%, when the prevalence of TB in the sample was 64.2%. Our results clearly show that the detection of antibodies which mainly react with the 38KDa antigen of M. tuberculosis is not suitable as the first-line method of diagnosis but considered only as an adjunctive test to standard techniques of tuberculosis diagnosis. when considering its high false positivity.

  • A necrotizing skeletal myopathy was diagnosed in three flocks of 30,000 thirty-eight-week-old layer breeder chickens. The mortality attributed to the myopathy was 17.7%, 12.3% and 21.1% in flock A, B and C, respectively. Clinically, chickens were showed depression, anorexia, posterior paresis, inability to rise, incoordination, reluctance to move, and leg trembling and weakness. The most striking findings at necropsy was pale streaking in the muscles of the thighs and legs. Microscopic lesions included myofiber degeneration and necrosis with massive cellular proliferation interpreted as sarcolemmal nuclei proliferation. Plasma creatine kinase, asparte aminotransferase and akaline phosphatase were markedly elevated. In conclusion, author suggested that submitted chickens were affected by ionophores poisoning.

  • In order to design and develop a product that can treat the fatty liver, natural complex food with all natural ingredients was developed and supplemented to rats with high fat diet to induce fatty liver. As a result, when the amount of natural complex food was increased in diet of subjects, the activities of the blood serum AST, ALT, ALP, 3-GT and LDH were decreased. The total protein concentration levels of the 30% and the 50% natural complex food groups did not show changes in respect to the control group, but the 100% natural complex food groups showed significant decrease (p<0.05). Likewise, the amount of blood serum albumin in the 30% and the 50% natural complex food groups did not show improvement, but the 100% natural complex food did showed significant changes (p<0.05). The amount of blood serum triglyceride decreased as the amount of natural complex food was increased. In order to investigate the appearances of the accumulated fat in the liver, the animals were dissected. Livers of the control group (no natural complex food) were appeared as a white color, which means serious fat accumulation. However, all the natural complex food groups (30,50 and 100% natural complex food) showed noticeable decrease of fat content. Even the histology showed that livers of the control group had expansion of the fat, but a11 the natural complex food groups had e decreased as the contents and continued to show destroyed fatty cells. By observing the biological numeric data, the physical appearance and the history of the fatty liver, it is highly expected that natural complex food is very effective in treating the liver damaged -by the to fat and the cholesterol.

  • Purpose : The accuracy of bacteriologic diagnosis of beta-hemolytic streptococcal pharyngotonsillitis depends on the degree of carrier rate in that area where the throat swabs are obtained and the evaluation of serological T typing as an epidemiologic marker is important to understand epidemiology of streptococcal infection. The purpose of this study is to know the carrier rates of group A streptococcus in normal children form four different areas and to find out the epidemiologic characteristic in distribution of the serotypes for 3 years. Method : Throat swabs were obtained from the tonsillar fossa of normal school children in four different areas(Uljin, Seoul, Osan, Kunsan) from March to May 1996, in Uljin in April 1997, and in Uljin in April 1998. The samples were plated on a 5% sheep blood agar plate and incubated overnight at $37^{\circ}C$ before examination for the presence of beta-hemolytic colonies. All isolated beta-hemolytic streptococcus were grouped and serotyped by T agglutination. Results : The carrier rate of beta-hemolytic streptococci and group A streptococci in 1996 were 27.6%, 18.6% at Uljin; 16.4%, 2.7% at Seoul; 33.0%, 26.0% at Osan; 20.0%, 12.3% at Kunsan, respectively. Among 1,192 normal school children from 4 different areas, we obtained 179 strains of group A streptococci. Fifty two percent of the strains were typable by T agglutination in 1996. Common T-type in 1996 were NT, T1, T3, T2 at Uljin; T12, T25 at Seoul; NT, T6, T28 at Osan; T25, T4, NT, T5 at Kunsan, in decreasing order, respectively. At Uljin, T1, T3, T25 accounted for 69% of strains in 1996, T1, T12, T25 accounted for 70% in 1997, and T12, T4 accounted for 88% in 1998. Conclusion : Higher carrier rates were found in Uljin and Osan, where there are a lower population density with scanty of medical facilities compared with another areas. We supposed that low carrier rates is likely to be related to antibiotic abuse or some epidemiologic factor. The periodic and seasonal serotyping analysis is important in monitoring and understanding the epidemiologic patterns of group A streptococci.

  • A direct complement fixation test supplemented with procomplementary porcine serum was studied using anticomplementary human, rabbit and bovine serum against Mycobacterium tuberculosis. Procomplementary activity of porcine serum varied with porcine individual and affected by anticomplementary antiserum. The procomplementary titre of porcine serum against rabbit, human and bovine serum ranged from 1:5 to 1:40. By means of complement fixation test supplemented by porcine serum, the specific complement-fixing antibody to both tuberculopolysaccharide and/or tuberculoprotein antigen was readily differentiated from the anticomplementary antibody titre.

  • Curcumin, a major polyphenolic compound of turmeric, is well known to prevent non-alcoholic steatohepatitis (NASH) related to obesity. The aim of the study was to investigate the effect of curcumin on hepatic fibrosis induced by carbon tetrachloride ($CCl_4$) in obese mice. $CCl_4$ was administrated in mice fed a normal diet (ND) or a high fat diet (HFD) for 7 weeks together with or without curcumin. It was conducted to examine for metabolic profiles, adipocyte size, and liver fibrosis by serum biochemistry, histology and immunohistochemistry. Also, Apoptosis of hepatic cells was determined by the TUNEL method. Treatment with curcumin significantly lowered the body weight, fasting glucose, serum AST and ALT, and decreased the adipocyte size, the number of macrophage and mast cells in adipose tissue, and collagen deposition in liver tissue in the HFD+$CCl_4$ group compared with the findings of the HFD+$CCl_4$ group. In contrast, treatment with curcumin on the ND+$CCl_4$ group did not show a significant difference except the body weight and mast cell number when compared with the ND+$CCl_4$ group. Furthermore, curcumin significantly reduced the number of parenchymal apoptotic cells, whereas it increased the number of non-parenchymal apoptotic cells, especially resembling an activated hepatic stellate cell in the liver. Taken together, this data suggests that curcumin might be an effective antifibrotic drug for the prevention of liver disease progression in obese mice. Thus, the development of curcumin as a therapy for obesity and liver fibrosis is supported.

  • Background : Recently, serologic techniques for tuberculosis have been developed and some of them, which are focusing on detection of serum antibodies mainly directed against specific 38-kDa Mycobacterium tuberculosis, have already been introduced into the markel. In this study, diagnostic significance of a new serologic test(ELISA kit) for pulmonary tuberculosis was evaluated. Method : Serologic test with newly developed ELISA kit was performed upon 474 individuals, who include 333 active pulmonary tuberculosis patients, 80 healthy cases, and 61 tuberculosis contact cases. This serologic test was based on the ELISA technique and designed to detect antibodies to mixed complex antigens including 38-kDa, which were developed by Erume Biotech Co., Seoul. Active pulmonary tuberculosis was diagnosed by sputum AFB smear and culture methods. Results : The seropositivities using this ELISA kit were 82.1% and 73.6% in smear-positive and negative groups among active pulmonary tuberculosis, respectively. And, it also showed that seronegativities were 97.5% and 85.2% in healthy and contact groups, respectively. As a whole, the results of our study using the ELISA kit as a diagnostic method for pulmonary tuberculosis showed 80.0% sensitivity for active pulmonary tuberculosis, 97.5% specificity, 96.1% positive predictive value, and 65.0% negative predictive value when the prevalence of tuberuclosis in the samples was 60.1%. Conclusion : Our results reveal that the detection of antibody its reaction with 38-kDa antigen of M. tuberculosis is not sufficient to be accepted as single diagnostic method for pulmonary tuberculosis. However, they suggest that ELISA kit may be considered as an adjunctive test to standard diagnostic techniques of pulmonary tuberculosis.

  • A 6-year-old, neutered female, Cocker spaniel presented with severe abdominal erythema and crusts. These conditions developed 1 month ago. This patient had a history of using humectant spray for several months. Irritant contact dermatitis was diagnosed by history, clinical signs, laboratory and histopathologic examinations (H-E stain). Complete blood count and serum chemistry showed no remarkable findings. Histopathologic examination of skin samples revealed parakeratosis accompanied by acanthosis of the dermis and mild perivascular inflammations of the superficial dermis. Clinical signs were improved after avoidance of suspected offending substance.
