A 7-year-old female Shih Tzu dog with lots of masses in the whole mammary gland was presented to the surgery department of the Veterinary Teaching Hospital in the Cheju National University. After surgical excision, all mammary samples were referred to Pathology Department of Veterinary Medicine. Grossly, masses were measuring up to $6.5{\times}4{\times}1cm$ and on cut surface of masses in right 1st, 3rd, 4th, 5th and left 1st, 3rd, 4th, 5th mammary masses were well delineated and firm, sulphur yellow, solid round to oval shape. Microscopically, most neoplastic sweat glands were severely proliferated in dermis and subcutis. Most tubules were lined by round to oval shaped epithelium with eosinophilic cytoplasm, hyperchromatic nuclei with high mitotic figures and severe central necrosis. The neoplastic epithelium also had PAS-positive diastase-resistant cytoplasmic granules, but negative with Perls iron stain. The left 2nd mass was well delineated, and had several dark brown areas and yellowish white glittered areas. Mass was well circumscribed with dense connective tissue. Neoplastic areas contained irregular sized mammary gland with papillary grown luminal epithelial cells in single or double cells layer with mitotic figures and small amounts of proliferated myoepithelial cells. Proliferated myoepithelial cells also produced slightly basophilic mucinous materials. Based on the gross, histopathologic and special staining characteristics, this dog was diagnosed as 90% of apocrine sweat gland aenocarcinoma and 10% mammary. complex adenomas in mammary masses. In our best knowledge, this is the first report for concurrent occurrence of apocrine sweat gland adenocarcinoma and mammary gland complex adenoma in mammary masses of the same dog.

In the original plant of Arisaematis Rhizomas, the features of external and internal shape of Arisaema amurense var. serratum $N_{AKAI}$ and A. amurense $_{MAXIM}$. are as follows. 1. In the external shape of original plant, Arisaema amurense var. serratum $N_{AKAI}$ has high stem, an oval-elliptic leaflet and a serrate leaf margin. But A. amurense $M_{AXIM}$ has a relatively low stem, an upside oval leaflet and no serrate leaf margin. 2. On the herbs character of original plant, Ansaema amurense var. serratum $N_{AKAI}$ is small in height and diameter, but A. amurense $M_{AXIM}$ is relatively large in height and diameter. 3. On the gathered herbs character of original plant, the section of Arisaema amurense var. serratum $N_{AKAI}$ is brightly white, easily spilt and strong scent. But the section of A. amurense $M_{AXIM}$ is thin yellowish brown, not easily spilt and weak scent. Also the grade of gathered herbs, both can be classified by diameter and external scent. 4. In the current herbs character, Korean and Sichuan Province products are irregullar shape and have no scent, Jilin Province products are regular shape. Also, Guangxi Province products are small size and concave in one side, Hebei Province products are irregular size and shape. 5. In internal shape of original plant, epidermal cell of Arisaema amurense var. serratum is very tight. With the except of micro difference in parenchyma cell of cortex, on the whole there are nearly no differences with A. amurense $M_{AXIM}$. Also, samely in the internal shape, according to collecting sites, epidermis exhibits a lot layer in curving state and secreting duct is developed and vascular bundle and exists between parenchyma cell of cortex. In the future, additional study is needed to distinguish herb and effect between same genus-degree of relatedness.

This study was carried out to clarify the genetic constitution of biochemical polymorphic loci controlling blood protein and enzymes as genetic rnarkers in Korean native chicken(KNG) population Blood samples were collected from 230 KNG representing three colored-lines(reddish-, yellowish- and blackish- brown) raised in Daejeon branch of National Livestock Research Institute. Eight blood marker loci, transferrin(Tf), post-albumin(Pas), albumin(Alb), amylase-1(Arny-1), es-terase-1(Es-1), alkaline phosphatase(Akp), catalase(Cat) and hemoglobin(Hh) were analyzed by using starch, agarose and polyacrylamide gel electrophoresis. Based on the gene frequencies of polymorphic marker loci, the genetic characteristics of KNF population was analyzed, and the genetic ariability within population was quantified. The genetic relationships between KNC and other native fowls or improved breeds were also estimated. The gene frequencies of Tf, Pas and AIb loci were similar to those of improved breeds among the seven biochemical polymorphic loci, while gene frequencies of Cat and Es-i loci were remarkably different between KNC and improved breeds. Gene frequencies of amy-i and Akp loci were similar to those of New Hampshire and Rhode Island Red and White Leghorn, respectively. However in comparison with other improved breeds, great differences were observed in gene frequencies of these loci The average heterozygosity, effective number of alleles and homogeneity index for the seven loci combined were estimated to be .334, 1.639 and .373, respectively. Based on the dendrogram and genetic distances, the KNC was genetically closer to New Hampshire, Plymouth Rock and Rhode Island Red breeds than to the White Leghorn breed.

Kudzu vine(Pueraria montana var. lobata) is an invasive climbing woody vine that envelops trees and shrubs, pressing physically and shutting out sunlight, which needs to be controlled. Kudzu vine pathogens were surveyed as a way to seek its biocontrol agents in 2002. Occurrence of a bacterial halo blight disease of kudzu vine was observed at several localities in Korea including Euiwang and Suwon in Gyeonggi Province, Daejon, and Gochang and Buan in Jeonbuk Province. Symptoms of brown to black spots with a surrounding yellowish halo appeared from June and lasted till the rainy season without much expansion, but accompanying often leaf blight and defoliation. Isolated bacteria were identified as Pseudomonas syringae pv. phaseolicola based on physiological and cultural characteristics, Biolog, fatty acid and 16S rDNA sequencing analyses. In artificial inoculation test, these bacteria produced the same halo spot symptoms on kudzu vine and bean plants. They also induced hypersensitive responses (HR) on tobacco, tomato, and chili pepper leaves. This is the first report of a bacterial disease of kudzu vine in Korea, and the bacterial pathogen can be used as a biocontrol agent against the pest plant.

A consecutive Jiao Chio acupuncture therapy was performed for 3 days in the 45-90 days old 11 calves of which have been shown severe watery diarrhea. The discharge of the infected calves was yellowish brown in color. Two calves of these patients were infected wi pulmonary disease as well as diarrhea. Thus, Su Qi and Fei Yu acupuncture therapy was carried out additionally after dosing with antibiotics twice for The two infected calves. Blood chemical values and serum neutralizing antibody titers were checked, and total blood cell count was also carried out to know the therapeutic effect before and after(21 days) acupuncture therapeutics. The results are as follows ; 1, The diarrhea has ceased one day after begining of the acupuncture therapy in 5 calves, and the cessation of the diarrhea in remaining calves occurred in 1 calf each on 3rd and 4th day, and 2 calves on 6th day, respectively. Two calves infected with pulmonary disease as well diarrhea were cured 8 days after the begining of the therapcutics. 2. Rotaviruses wire detected in the feces of 2 calves, and bovine diarrhea viruses were detected in the 8 calves by the test for serum neutralizing antibody titers, and bovine coronaviruses were also detected in 5 calves. Four calves of the 5 bovine coronavirus infected calves were also infected with bovine diarrhea viruses. 3. Total leucocyte number, total amount of serum protein, and amount of fibringen were slightly increased, while total erythrocyte number, and erythrocyte packed cell volume were slightly decreased. These valucs were statistically not significant. Electrolytes of Na/sup +/, K/sup +/ and Cl/sup -/ were slightly decreased but these values also were not significant. These results indicate that the acupuncture therapeutics arc significantly effective to remove the viral diarrhea in the young calves.

This study was undertaken to evaluate the drinking water quality based on physicochemical properties and chemical compositions of the supply water in the Daedeok Campus, and to verify the analytical reliabilities of ICP-MS and IC equipped in the Central Research Facilities at Chungnam National University , Korea. The supply water belongs to $Ca^{2+}-({HCO_3}^-+{SO_4}^{2-})$type, whereas the original water from the Daecheong lake belongs to $(Ca^{2+}-(Mg^{2+})-{HCO_3}^-$ type. Generally, temperature (14.1$^{\circ}C$), pH (6.95), Eh (0 mV), electrical conductivity (117${\mu}$S/cm) and TDS (86.975mg/l) of supply water were higher than those of original lake water . Results using WATEQ4F revealed that potentially toxic ions of the supply water might exist mainly as free metals ($M^{2+}$) and a small amount as ${CO_3}^{2-}$ and $OH^-$ complexes. Also, the water composition belongs to the kaolinite field. Calculated average enrichment indies of the supply water normalized to lake water for anions, mamor cations, toxic cations and total ions are 1.05 , 1.56, 13.05 and 1.17 , respectively. Those values of the ground water in the Daedeok Campus showed 1.71, 4.78, 5.71 and 2.49 , respectively. However , contents of all constituents of these water are within the drinking water standard. All samples were filtered before the chemical analysis. Pale yellow or yellowish brown colored materials of colloidal particles coated the filter paper to thickness of 0.02 to 0.2mm. these are mainly Fe-Cy-Zn compounds with traces of Ni and Pb, the net weights of which compounds range from 0.01to 3.20mg/l. Most elements did not show any conceivable filtering effect of Cu, Fe and Zn. Especially, mean concentration of total Fe decreased considerably from 168.52${\mu}g$/lto 42.58${\mu}g$/l by filtering .
