Tuberculous peritonitis is a rare cause of intra-abdominal infection. Although sometimes asymptomatic, most of the patients have fever, weight loss, abdominal pain, and edema. The diagnosis of tuberculous peritonitis is difficult and sometimes delayed because of confusion of the disease with other illnesses and the non-specificity of signs and symptoms. Tuberculous peritonitis is examined with ultrasonography and computerized tomogram, but confirmed by biopsy or tuberculosis culture. Ascitic fluid is exudates with a lot of lymphocytes and elevated protein. Tuberculous peritonitis is treated successfully with isoniazid, rifampicin for one year, pyrazinamide for first 2 months and streptomycin for first one month. We experienced one case of tuberculous peritonitis with transudate of ascitic fluid, confirmed by biopsy using colonoscopy, and treated successfully.

Purpose: Hydrofluoric acid(HF) is one of the most dangerous mineral acids with the dissociated fluoride ions. The initial corrosive burn is caused by free hydrogen ion, and the second and more severe burn is caused by penetration of fluoride ions into subcutaneous tissues. Silver is a cation producing dressing, an effective antimicrobial agent, but older silver-containing formulations are rapidly inactivated by wound environment, requiring frequent replenishment. But, $Acticoat^{(R)}$ is a relatively new form of silver dressing which helps avoid the problems of earlier agents. The aim of this study is to evaluate effects of $Acticoat^{(R)}$, silver-containing dressing on the treatment for HF injury wound. Methods: From september 2006 to september 2007, the study was carried out with 10 patients who had HF partial thickness burns. $Acticoat^{(R)}$ dressing and 10% calcium gluconate wet gauze dressings in 10 cases. As a principle, in the emergency treatment, partial or complete removal of the nail and early bullectomy along with copious washing with normal saline was done, depending on the degree of HF invasion of the wound. Wound was dressed with $Acticoat^{(R)}$ and 10% calcium gluconate solution. The effect of dressing was investgated by serial bacterial culture and wound exudates assessment. Results: We therefore reviewed 10 cases of HF-induced chemical burns and treatment principle. The 10 cases who came to the hospital nearly immediately after the injury healed completely without sequelae. Conclusion: As the industrial sector develops, the use of HF is increasing more and more, leading to increased incidences of HF-induced chemical burns. The education of patients regarding this subject should be empathized accordingly. In conclusion, $Acticoat^{(R)}$ dressing is a better choice for HF partial thickness burn injuries because of shorter healing time, less pain and more comfortable dressing.

Bupleurum falcatum has been used for treatment of inflammation, jaundice, influenza and hepatitis as a traditional orient folk medicine. This experiment was carried out to evaluate the effect of B falcatum extract on cellular immune responses in vivo and in vitro. Antigen binding cell(ABC) assay, antibody production, Arthus and delayed-type hypersensitivity(DTH) reaction against sheep erythrocytes(SRBC) were very depressed in B falcatum extract treated group in vivo. The growth of Staphylococcus aureus in brain heart infusion(BHI) broth containing B falcatum extract was remarkably inhibited. Otherwise, that of Salmonella typhyimurium was not significantly increased in vitro. When B falcatum extract pretreated mice were intraperitoneally(IP) injected S typhimurium and S aureus, respectively, the number of bacteria in peritoneal exudates were time dependent declination compared with those of control, and the weight of spleen and the number of macrophage migration into peritoneal cavity have no difference from those of untreated control. B falcatum extract gradually increased phagocytic activities of peritoneal macrophage against Candida albicans time and dose dependently, and was not significant production of migration inhibiotory factor(MIF). But migration abilities of normal leucocytes in B falcatum extract pretreated group were decreased dose dependently. When B falcatum extract was IP administered, these data indicate that B falcatum extract increases level of serum coticosterone. Therefore, B falcatum extract was indirectly mediated in immune system by serum coticosterone having relation to immunosuppression. These results lead to the conclusion that B falcatum extract acts as a trigger or regulator of cellular immune responses in immune system.

Eight dogs were presented with anal sacculitis with purulent exudates and/or open in the right or left anal sac. Patient dogs, ranging in size from 3-to-8 kg, were treated with closed anal sacculectomies, in which the balloon of a Foley catheter (No. 6, 1.5 ml) was used to facilitate surgical dissection of the sac. In all cases, the Foley catheter successfully distended the anal sac during its removal. Clinical signs associated with the diseased anal sac were abated In the all dogs for a follow-up period of one-to-three months. Anal sacculectomy is a good therapeutic option for cases of chronic anal sacculectomy or impaction. The use of a small Foley catheter to distend the anal sacs during surgery was easy, Inexpensive, and successful.

The purpose of this study is to investigate growth response and toxigenicity under various temperature and nutritional conditions, in order to understand the physioecological characteristics of Aphanizomenon flos-aquae, which is a bloom-forming cyanobacterium in the Nakdong River. The strain was inoculated into media under combinations of four temperatures (4, 12, 21, $30^{\circ}C$) and three nutrients (modified CB medium, P-depleted CB medium, N-depleted CB medium) for 28 days. The algae-inhibition tests were performed to assess the potential allelopathic effects of the strains' filtrates on the growth of four algae strains (Microcystis aeruginosa, Aulacoseria ambigua f. spiralis, Aphanizomenon flos-aquae, Scenedesmus obliquus). Toxin production of a strain was measured by Enzyme-Linked ImmunoSolbent Assay (ELISA). The optimal growth temperature (Topt) of strains was $19.9^{\circ}C$ ($18.3-21.2^{\circ}C$), and the temperature range for growth was from $-0.3^{\circ}C$ to $34.3^{\circ}C$. Specific growth rate (${\mu}$) in modified CB medium varied from 0.10 to $0.16day^{-1}$, and the maximum growth rate (${\mu}_{max}$) was $0.17day^{-1}$. Although growth curves under N-existed and N-depleted conditions were almost the same, growth under N-depleted condition was relatively slowed (${\mu}=0.09$ to $0.14day^{-1}$), with a decreased maximum cell density. However, growth under the P-depleted condition was restricted for all temperatures, Two stains of Aphanizomenon flos-aquae were confirmed as not producing toxins, because saxitoxin and cylindrospermopsin were not detected by ELISA. The exudates or filtrates from the Aphanizomenon flos-aquae (DGUC003) resulted in significant inhibition of algal growth on the Aulacoseira ambigua f. spiralis (DGUD001) and Aphanizomenon flos-aquae (DGUC001) (p < 0.01).

Prosopis juliflora and Parthenium hysterophorus are the two arid, exotic weeds of India that are characterized by distinct, profuse growth even in nutritionally poor soils and environmentally stressed conditions. Owing to the exceptional growth nature of these two plants, they are believed to harbor some novel bacterial communities with wide adaptability in their rhizosphere. Hence, in the present study, the bacterial communities associated with the rhizosphere of Prosopis and Parthenium were characterized by clonal 16S rRNA gene sequence analysis. The culturable microbial counts in the rhizosphere of these two plants were higher than bulk soils, possibly influenced by the root exudates of these two plants. The phylogenetic analysis of V1_V2 domains of the 16S rRNA gene indicated a wider range of bacterial communities present in the rhizosphere of these two plants than in bulk soils and the predominant genera included Acidobacteria, Gammaproteobacteria, and Bacteriodetes in the rhizosphere of Prosopis, and Acidobacteria, Betaproteobacteria, and Nitrospirae in the Parthenium rhizosphere. The diversity of bacterial communities was more pronounced in the Parthenium rhizosphere than in the Prosopis rhizosphere. This culture-independent bacterial analysis offered extensive possibilities of unraveling novel microbes in the rhizospheres of Prosopis and Parthenium with genes for diverse functions, which could be exploited for nutrient transformation and stress tolerance in cultivated crops.

The phenomenon of sail sickness in the continuous cropping of ginseng is n serious problem for the cultivation practices and is an unelucidated subject scientifically. Present study is concerned mainly with ecochemical search on the cause of soil sickness in the continuous cropping of ginseng and the obtained results are summarized as follows: The humic substances isolated from both cultivated and uneulvidated soils with ginseng were compared with respect to its IR spectra but any difference which may be causative of sail sickness between them was not detected. In contrast, same saponin-like substances extracted from the ginseng cultivate soil in root tone were detected but not from the uncultivated soil. Presumably. the saponin like substances in the soils are originate) from the ginseng radices and are accumulaetd in root zone year by year, while the interrelation between the root exudate of ginseng and soil sickness is still obscure. According to a survey on the distributive Pattern of microflora in rhizosphere of ginseng radices the number of fungi is relatively diminished with the cul tivation years, while the number of actinomycetes is increased. It is supposed that the soil sickness in the continuous cropping of ginseng has any correlation between the activities of microflora in rhizosphere and the reef exudates.

This study investigated cases of progressively necrotizing limbs in Korean indigenous calves. The recent case (Case 1) involved a 3-month old, male calf in Jeonbuk province that presented a visibly dry form of gangrene affecting joints of the forelimbs and the hind limbs. Radiograph revealed osteoarthritis possibly resulting from pressure of disrupted joint skin, fasciae, deeper underlying musculatures and tendon. Histopathology of affected tissue showed necrotizing; severely thrombosed dilated blood vessels with rechanneling microvasculatures. The lack of substantial infectious inflammatory exudates in the vital organs and the inability to respond to antimicrobial treatment bolstered the notion that the observed thromboembolic and vascular lesion was attributed to possible vasoconstrictive effects of ergot alkaloids. Case 2: A previously encountered similar case in a 4-month old, male calf showing gangrene of hind limbs and posterior ataxia was likewise presented. These two cases were impressed as probable ergotism. Ergotism may be uncommon or underreported in Korea. Future isolation of ergot alkaloids in feeds or in pasture is highly suggested.

Fowl cholera is a contagious acute and chronic disease caused by Pasteurella multocida in both domesticated and wild birds. Acute fowl cholera in both chickens and wild birds has recently been documented in Korea, but the chronic form has not been reported in Korea until now. This study describes the first outbreak of chronic fowl cholera in 13-week-old Arbor Acre broiler breeder chickens submitted to the College of Veterinary Medicine, Kyungpook National University in April 2006. The clinical signs of the affected flock of 9,621 chickens were lameness caused by swollen hock joints, diarrhea, ruffled feathers, and an average weekly mortality of 1.0%. At necropsy, purulent or caseous exudates were found in the hock and wing joints, humerus, and eyes, and severe pneumonia and pericarditis were discovered. Eleven bacterial isolates obtained from the liver, joint, infraorbital sinus and sternal bursa of the submitted chickens were all identified as Pasteurella multocida based on their physiological and biochemical characteristics. Five isolates were examined for antimicrobial susceptibility against 21 different antimicrobial agents including ampicillin. All were resistant to kanamycin, neomycin, and streptomycin, and some were resistant to gentamicin. The tested isolates were all susceptible to the other 17 antimicrobial agents. All 11 isolates were capsular serogroup A based on multiplex polymerase chain reaction. In addition, two of five isolates used in the antimicrobial susceptibility test were identified as somatic serotype 1 by an agar gel diffusion precipitin test, while the others were non-typable.

Stomachs from 3,354 fattening pigs were examined at slaughter during the period from September 1980 to August 1981. Pigs of both sexes and $Landrace{\times}Hampshire$ crossbreds were included in the present studies, and they weighed about 60-120kg. Gross pathologic alterations of the stomach were classified as normal, epitnelial change, erosion, ulcer and scar formation. Representative tissue sections were taken from the stomach lesions at random and fixed in 10% buffered formalin. Cut sections were stained with hematoxylin and eosin, and examined histopathologically. The results obtained in the present studies were as follows. 1. In the seasonal prevalence of gastric ulceration, severe ulceration with erosion was shown during the Autumn and Winter, whereas mild ulceration was mainly shown during the Spring and Summer. 2. Of the 3,354 stomachs of the pigs, 20.8% were found to be normal. Of the rest, 40% had epithelial changes, followed by erosion (24.7%), ulcer (13.6%) and scar formation (0.9%), respectively. 3. In the prevalence of ulcers in the different regions of the stomach, the fundic region had the highest rate (61.6%) of ulceration, followed by cardiac (21.7%), esophageal (15.0%) and pyloric region (1.7%). 4. The principal gross changes were severe epithelial changes with keratotic proliferation in the esophageal region, and in the fundic region severe folding of the stomach wall was covered with bloody mucous exudates. 5. Main histopathological changes were inflammatory cell infiltrations in most cases, hemorrhages in acute ulcers and prominent proliferation of granulation tissues in chronic ulcers.
