The anthelmintic efficacy of Albendazole and Ivermectin against gastrointestinal nematodes, trematodes and cestode was tested in naturally infected Korean native goats. Albendazole was medicated at a dose rate of 10mg/kg of body weight orally and Ivermectin was injected at a dose rate of 0.2mg/kg of body weight subcutaneously. The efficacy was measured by faecal examinations on the day 7th and the day 14th after treatment

The purpose of this study was to develop a new method which enables the goat ESR to be used as an effective clinical test. Blood samples were taken from 61 Korean native goats aged above one year old and the effect of tube inclinations, tube bores, tube lengths, environmental temoeratures during tests and packed erythrocyte volumes (PCV) on the ESR were observed. The ESR/hr using capillary hematocrit tube (Micro-Ht-tube) was gradually increased as the tube angle inclined from 90 (vertical) to 15 degrees and the best angle in view of both security and fast sedimentation rate was found to be an angle of 45 degrees

Isolation of Staphylococcus hyicus subsp. hyicus from piglets suffering from exudative epidermitis and healthy pigs was performed, and some properties of the isolates were examined. Twenty-six litters of exudative epidermitis observed in the field were sucking piglets with ages ranging from 1 to 5 weeks and most (73.1%) of these cases occurred in piglets between 2 and 3 weeks of age. Staphylococcus hyicus subsp. hyicus was isolated from 192 (38.9%) of 494 healthy pigs. The rate of isolation of these organism from healthy pigs was found to vary greatly among farms at an isolation rate of 33.3% to 45.5% and this organism was isolated more frequently from sucking piglets below the age of 8 weeks than adult pigs

The arterial supply to the eyeball of the Korean native goat has been described. Observations were made by dissection of ten Korean native goats fixed in embalming fluid and injected with neoprene latex. The eyeball and accessory ocular organ of the Korean native goat received its blood supply chiefly from the A. ophthalmica externa and partly from the branches of A. temporalis superficialis and A. malaris. A. ophthalmica externa formed Rete mirabile ophthalmicum after giving off Ramus muscularis and A. lacrimalis, and continued to A. supraorbitalis

The oil emulsion and alhydrogel pilli vaccines were prepared from a strain (O9: K35, K99, F41) of enterotoxigenic Escherichia coli isolated from calves with diarrhea and their immunogenicity was tested in guinea-pigs, pregnant goats and cows. Serum antibody responses to K99 and F41 antigens in guinea-pigs given experimental oil and gel vaccines peaked at 4 and 6 weeks after vaccinations. At that time, the mean hemagglutination inhibition titers to K99 and F41 antigens in guinea pigs given oil vaccine were 1:25 and 1:1,218 and those given gel vaccine were 1:54 and 1:724 respectively

The bovine serum influencing the growth of swine testicle (ST) cell and the END effect of hog cholera SN test was studied. Bovine whole serum of 16 (76.2%) and 4 (19.0%) samples out of 21 have shown a positive ST cell growth and the END effect, respectively. However, all of 21 (100%) and 8 (38.1%) samples out of 21 serum supernatant fractions, prepared from the bovine whole serum, have shown positive ST cell growth and END effect, respectively

Progesterone immunogen has been synthesized and its melting point, Rf-value, UV and IR spectrum have been measured to develop the essential step in antisera production against low molecular weight substance. Mixed anhydrid reaction was used to conjugate 11 alpha-hydroxy-progesterone with succinic anhydride. Melting point of one intermediate compound was 156 deg C, and Rf-value was 0.41 in benzene: acetone: methanol (5:5:2).

Samples of feces from 1,080 cattle than in Chonnam area were examined for Buxtonella sulcata. Of these, 231 cattle (21.4%) were found to be infected with the ciliate. The incidence was higher in the dairy cattle in the beef cattle. The cysts of the ciliate were almost spherical or sub-spherical and the mean length of 79.58 +- 11.76 micro m corresponds quite closely with the mean width of 77.29 +- 11.41 micro m. The trophozoite was characterized by the position of the cytostome near the open cytopyge and by the curved groove running down from cytostome to the end of the body

Four colostrum-deprived, 1 day old pigs were orally infected with the porcine enterovirus isolated in Korea. Two of the pigs were treated with dexamethasone (5mg/kg/day) for 3 days. The others as control were infected with porcine enterovirus only. The treated, infected pigs developed ataxia at 3 postinoculation days, neural disorders at 8 postinoculation days, 1 week earlier than those of the controls. Histopathological examination of both the treated and the control pigs revealed non-purulent polioencephalomyelitis consisting of neuronal degeneration, perivascular cuffing, meningeal infiltration, focal and diffuse gliosis. The severity of the histopathological lesions in the treated pigs was more prominent than those of the controls

In order to clarify the pathogenesis of perirenal edema, pigs and rabbits were administered with oxalate and nitrate, with oxalate nitrate and glycolic acid, with oxalate, nitrate and ascorbic acid and with oxalate, nitrate and calcium, respectively. The pigs and rabbits administered with oxalate and nitrate with oxalate, nitrate and glycolic acid and with oxalate, nitrate and ascorbic acid, respectively, were not showed perirenal edema despite of observing the abundant oxalate crystals in the proximal convoluted tubles
