  • A gingival mass was detected from a 1-year-old female Great Dane dog. After surgical removal, the lesions recurred in 2 weeks and died of septicemia. Characteristic histologic features were large numbers of multinucleated giant cells which were connected with capillary vessels. Neovascularization was prominent with mononuclear and polynuclear cell infiltration. Overall features of these lesions except for giant cell infiltration were similar to granuloma. From these results, a gingival mass excised from a dog was diagnosed to be a peripheral giant cell granuloma (PGCG). This is the first report of canine subcutaneous PGCG in Korea.

  • The dinuclear complex 1 with cooperative hydrogen bonds can be prepared by the metal-directed reaction of Eq. (2). This work shows that the coordinated hydroxyl group trans to the secondary amino group is deprotonated more readily than that trans to the tertiary amino group and acts as the hydrogen-bond accepter. The lattice water molecules in 1 act as bridges between the two mononuclear units through hydrogen bonds. The complex is quite stable as the dimeric form even in various polar solvents. The complex exhibits a weak antiferromagnetic interaction between the metal ions in spite of relatively long Cu$\cdots$Cu distance. This strongly supports the suggestion that the antiferromagnetic behavior is closely related to the cooperative hydrogen bonds.

  • A survey on pneumonic lungs and its histopathological changes of the slaughtered pigs from the southern area of Chungbuk province was carried out during the period from January to December 1999. Pneumonic lungs were attempted bactenological findings and antibiotic susceptibilities. The results obtained were as follows; 1. Of 158 slaughtered pigs, 97(61.4%) pigs had pneumonic lesions in the lung, and the prevalence was high in winter, spring, autumn, and summer in order. f. The bacteria isolated from pneumonic lesions were pasteurella spp, 13 heads(34.2%), streptococcus spp, 6(IS.8%), actinobacillus spp, 3(7.9%), coliform 4(10.5%) and the other bacteria, 12(31.6%). 3. These isolates were highly susceptible to the antibiotics of enrofloxacin 30(78.9%), cephalothin 23(73.6%) and ceftiofur 27(71 %). 4. Histopathologically, swine enzootic pneumonia and pleuropneumonia lesions were observed. The swine enzootic pneumonia lesions were consisted of peribronchiolar lymphoid hyperplasia and exudate in alveolar lumen. The pleuropneumonia lesions were consisted of thrombosis, alveolar wall thickened by mononuclear cells and neutrophil deposition.

  • The design, synthesis, and structural characterization of two new palladium complexes based on Schiff base ligands is reported; $[Pd(L1)_2]$ (1) and $[Pd(L2)_2]$ (2), [HL1 = 2-((E)-(2,6-diethylphenylimino)methyl)-4,6-dibromophenol, L2 = (E)-N-benzylidene-2,6-diethylbenzenamine], which are obtained by functionalizing Schiff base ligands with or without electron-withdrawing groups. Both compounds are mononuclear structures. Comparisons are made to the compounds 1 and 2 to analyze and understand the effect of electron-withdrawing groups. Antibacterial activity studies indicate the electron-withdrawing groups on Schiff base ligands enhance antibacterial activity. Catalytic activity, however, is reduced due to the enhanced steric-hindrance of the electron-withdrawing groups. Electronic absorption and emission properties of HL1, L2, 1 and 2 are also reported.

  • The interaction of titanium (IV), yttrium (III), zirconium (IV), palladium (II) and cerium (IV) with deprotonated enrofloxacin leads to the formation of the neutral or cationic mononuclear complexes. The isolated solid complexes have been characterized with physicochemical and spectroscopic techniques and thermogravimeteric analyses. The spectroscopic data indicate that the enrofloxacin ligand is on the deprotonated mode acting as bidentate ligand coordinated to the metal ions through the ketone oxygen and a carboxylato oxygen and the metal ions completed the coordination number with water molecules. The thermal decomposition mechanisms proposed for enrofloxacin and their metal complexes were discussed. The activation energies, $E^*$, enthalpies, ${\Delta}H^*$, entropies, ${\Delta}S^*$ and Gibbs free energies, ${\Delta}G^*$, of the thermal decomposition reactions have been derived from thermogravimetric (TG) and differential thermogravimetric (DTG) curves, using Coats-Redfern (CR) and Horowitz-Metzeger (HM) methods. The antimicrobial activity has been evaluated against six different microorganisms.

  • A new tridentate ligand incorporating a monoxime and thiosemi-carbozone moieties has been synthesized. Its copper(II), nickel(II) and palladium(II) complexes have been prepared and characteirzed by physical and spectral methods. Elemental analyses and spectroscopic data of the metal complexes are consistent with the formation of a mononuclear copper(II) complex and binuclear complex with both nickel(II) and palladium(II). In the copper(II) complex the fourth coordination site is occupied by nitrate ion. In the binculear complexes the fourth coordination site is occupied by the deprotonated oxime oxygen of the ligand coordinated to the other metal.

  • In order to investigate the effects of shipjuntaepotang (少陰人 十全大補湯) on immune response, the author performed this experimental study. Delayed type hypersensitivity (DTH) and rosette forming cells (RFC) for cell-mediated immune response, hemagglutinin (HA) titers, hemolysin (HL) titers, and carbon clearance for phagocytic function of MPS (mononuclear phagocyte system) were measured in ICR mice. The results were summarized as follows. 1. DTH in the experimental group was increased, as compared with the control group, with statistical significance. 2. RFC in the experimental group was increased, as compared with the control group, with statistical significance. 3. HA-titers were increased in the experimental group, as compared with the control group, with statistical significance. 4. HL-titers were increased in the experimental group, as compared with the control group, with statistical significance. 5. Carbon clearance was increased in the experimental group, as compared with the control group, with statistical significance. Through invivo experimental study in ICR mice, these findings suggest that shipjuntaepo-tang enhance both cellmediated and humoral immune responce.

  • 고양이 말초혈액 다형핵백혈구(PMNC)의 유주성에 있어서 인삼 saponins(ginseng total ssponin(GTS), ginseng PT saponin(GfT) 및 ginseng PD saponin(GPD))의 면역증강 효과를 검토하였다. PMNC에 대한 유주성을 hoyden chamber 변법으로 측정한 결과, GTS, GPT, GPD는 PMNC에 대해 직접적인 유주활성을 나타내지 않았다. 또한 인삼 saponins을 첨가하여 배양한 PMNC 배양상충액의 경우게는 미약한 유주활성을 나타내었다. 그러나 GPf및 GPD를 첨가하여 배양한 말초혈액 단핵구세포(MNC)배양상충액에서는 PMNC의 유주활성이 현저하게 증가하였다. PMNC에 대해 유주활성이 인정된 GPI)로 배양한 MNC 배양상충액을 이용하여 checkerboard assay를 실시한 결과 배양상충액의 농도차에 의존하는 진의 유주활성임을 알 수 있었다. 이상의 결과로부터 인삼 saponine 중 GPT 및 GPD가 고양 이 말초혈액 다형핵백혈구의 유주성을 중강시키는 효과가 있으며, 이것은 이들 saponins에 의해 활성화된 단핵구세포에서 분비되는 유주성인자에 의해 다형핵백혈구의 유주활성이 증 강되는 것으로 사료되었다.

  • 고양이 말초혈액 탐식세포(단핵구세포(MNC) 및 다형핵백혈구(PMNC))의 탐식능 에 있어서 인삼 saponin(ginseng total saponin(G75), ginseng PT saponin(GPT) 및 ginseng PD saponin(GPD))의 면역증강 효과를 flow cytometry를 이용하여 분석하였다. 인삼 ssponins을 직접 첨가하여 배양한 MNC 및 PMNC에서는 탐식중강 효과가 나타나지 않았다. 각각의 인삼 saponin을 첨가하여 배양한 PMNC 및 MNC 배양상충액의 존재하에 PMNC 및 MNC의 탐식능을 겅토한 결과, MNC의 탐식능은 Gff 첨가 PMNC 배양상충액과 GTS 및 GPT 첨가 MNC 배양상충액의 존재하에서 약간의 탐식증강 효과를 보였다. PMNC 탐식능의 경우에는 GPD 첨가 PMNC 배양상충액에서 미약한 탐식증강 효과가 나타났으나, 각각의 인 삼 saponin 첨가 MNC 배양상충액 존재하에서는 모두 현저한 탐식중강 효과를 나타내었다. 이상의 결과로부터 고양이 말초혈액 탐식세포의 탐식증강 효과는 인삼 saponin의 직접적인 작용보다는 인삼 saponin에 의해 활성화된 단핵구세포에서 분비되는 가용성물질에 의해 단 핵구세포보다는 다형핵백혈구에서 현저하게 탐식효과가 증강되는 것으로 판단되었다.

  • A dead, female, 3 years old, squirrel monkey (Saimiri sciureus) was submitted and examined. Before death the monkey has showed lethargy, recumbency and inappetence since November 14, 2001 and died in November 17. Grossly much fibrin was deposited on the pleura of right lung, pericardium, and diaphragm(pleural part). And reddening of right lung was seen. Histopathologically lung showed severe fibrinous pleuritis, severe edema, thrombosis, and focal necrosis in parenchyma. Also much fibrin and mononuclear cells were deposited on the pericardium. In bacterial culture on the pleura and parenchyma of lung, and pericardium, B. bronchiseptica was isolated. Therefore we confirmed this case as the fatal case by B. bronchiseptica in squirrel monkey.
