A immunological survey of paratuberculosis in dairy and Korean native cattles was conducted by enzyme linked immunosorbent assay(ELISA), complement fixation test(CFT), agar gel immunodiffusion test (AGID) and intradermal skin test(ID). Over all prevalence of pararuberculosis in cattles was 6.7%(109/1633) by ID, 7.5(205/2719) by AGID, 9.3% (245/2641) by CFT and 13.4%(363/2719) by ELISA. Prevalence in dairy cattle was higher than that of Korean native cattle. Of 70 ELISA-positive cattle, 23(28.6%) and 48(68.6%) cattles were classified as positive in the AGID and positive or suspect in CFT, respectively. Of 92 ELISA-suspect cattle, 32(34.9%) and 48(52.2%) cattles were classified as AGID-positive and CFT-positive or suspect, respectively. It was concluded that paratuberculosis is widespread in cattle of Korea.

김종만,이성식,김요태,Kim, Jong-Man,Lee, Seong-Sik,Kim, Yo-Tae 고려인삼학회 1981 Journal of Ginseng Research Vol.5 No.2

Ginseng seeds were gathered from 3,4,5 and 6 years of age and were classified into four qroups (below 4mm, 4∼5mm, 5∼6mm and above 6mm in across sieve). They were sown in seedling bed and some characters were investigated in each qroup of seed size. 1. The distribution of seed size of below 4mm, 4-5mm, 5-6mm and 6mm were 23.7%, 60.8%, 12.4% and 4.5%, respectively. 2. The ratio of seed coat dehiscence was not affected by seed size but emergence ratio and emerging vigor were superior in large seed. 3. The large seed showed superiority in stem length, stem diameter, leat and also in root length, root diameter and root weight. but diseased root was not affected by seed size. The effect of age(seed harvest) was not significant on all those characters.

This experiment was carried out to inverstigate the characteristics of growth of ginseng Plant on field conditions as affected by seedling weight. Weight of seedling ranged from 0.4 to 1.8g were divided into seven classes at interval of 0.2g. The heavy seedlings showed superiority in stem length, stem diameter, leaf area, number of palmate leaf and leaflets and root weight in 2-,3-, and 4-age as compared to light ones. The heavy seedlings also showed superiority in the ratio of inflorescence appearance in 2-age and seed product in 4-age as compared to light ones, but there were no significant difference in the ratio of missing-plant and the cracking. of root. The differences of growth in field condition as affected by seedling weight were diminished as the age progressed, and the annual growth rates of root of light seedling were high in older plant.

It was planned and performed to study the possibility on the use of inexpensive and easily acquirable foliage powder, which processed by pulverizing after dried, instead of imported expensive wheat flour for the extending of plywood adhesives. Pine leaves of softwood trees, Poplar, Oak and Sycamore leaves of broad leaved species were selected and harvested to pulverize into the minute foliage powder. The harvested foliages from each selected species were pulverized into 40 mesh particles after dried at 100∼105℃ condition during 24 hours in drying oven. To compare the extending effect of plywood adhesives with these foliage powders 100 mesh wheat flour using at current plywood industry was also prepared. Foliage powder and wheat flour were extended into 10, 20, 30, 50 and 100% to the urea and phenol formaldehyde resin. After plywoods were processed by the above extending method shear strength of extended plywoods were analyzed and discussed. The results obtained at this study are as follows: 1) Among 10% extensions of urea formaldehyde resin plywood, dry shear strength of plywood extended by wheat flours was the highest and that of non-extended plywood the next. Plywood extended with foliage powder showed the lowest dry shear strength. The order of dry shear strength of plywoods extended by foliage powder was that of Oak foliage powder extension, the best, that of Sycamore, that of Pine, and that of Poplar. 2) Among 20% extensions of urea formaldehyde resin plywood, plywood extended by wheat flour showed the highest dry shear strength, and the next was plywood by Poplar foliage powder. All these two showed higher dry shear strength than non-extension plywoods. Except Poplar, dry shear strength of foliage powder extension plywoods was bad, but the order of dry shear strength of plywoods extended by foliage powder was Pine, Poplar and Oak. 3) In the case of 30% extensions of urea formaldehyde resin plywood, dry shear strength of wheat flour extension was the highest and non-extension the next. Dry shear strength of foliage powder extension plywoods was poor with a rapid falling-off in strength. 4) Among 50% and 100% extensions of urea formaldehyde resin plywood, only wheat flour showed excellent dry shear strength. In the case of foliage powder extension, low dry shear strength showed at the 50% extension of Pine and Poplar, and plywoods of 50% extension of Oak foliage powder delaminated without measured strength. All plywoods of 100% foliage powder extension delaminated, and then shear strength were not measured. 5) Among wet shear strength of 10% extensions of urea formaldehyde resin plywood, wheat flour extension was the highest as in the case of dry shear strength, and non-extension plywood the next. Except Poplar foliage extension, all foliage powder extension plywoods showed low shear strength. 6) Wet shear strength of plywoods of 20% extension lowered in order of non-extension plywood, plywood of wheat flour extension and plywood of foliage powder extension, but other plywoods of foliage powder extension except plywoods of Poplar and Oak foliage powder extension delaminated, 7) Wet shear strength of 30% or more extension of urea for madehyde resin plywood were weakly measured only at 30% and 50% extension of wheat flour, and wet shear strength of plywoods extended by foliage powder were not measured because of delaminating. 8) Dry shear strength of phenol formaldehyde plywoods extended by 10% wheat flour was the best, and shear strength of plywoods extended by foliage powder were low, but the order was Oak, Poplar, and Pine, Plywood of Sycamore foliage powder extension delaminated. 9) In the case of 20% extensions of phenol formaldehyde resin, dry shear strength of plywood extended by wheat flour was the best, but plywood of Pine foliage powder extension the next, and the next order was Oak and Poplar foliage powder. Plywood of Sycamore foliage powder extension delaminated. 10) Among dry shear strength of 3

Survey on MIC of antimicrobial drugs and its treatment efficacy in mice were conducted for the strains of Escherichia coli and Salmonella spp isolated from feces of young domestic animals with diarrhea in 1996. A total of 338 strains of E coli and 61 strains of Salmonella spp were examined for the susceptibility to 20 antibiotics and 7 synthetic antimicrobial drugs. The results indicated that the majority of strains were susceptible to amikacin(93.5%), cefoperazone/sulbactam(93.5%), cefotaxim(93.3%), cefomandole(92.8%), cefoperazone(91.6%) and ciprofloxacin(85.1%), in order. Although gentamicin, ciprofloxacin and norfloxacin showed the relatively low MIC distributions, erythromycin, doxycycline, sulfamethoxazole and oxytetracycline revealed the high MIC distributions to most of isolates. The $MIC_{90}$ of antimicrobials for E coli were > $62.5{\mu}g/ml$ in gentamicin, $2.0{\mu}g/ml$ in ciprofloxacin, $1.0{\mu}g/ml$ in norfloxacin, > $500{\mu}g/ml$ in erythromycin, $125{\mu}g/ml$ in doxycycline, > $1000{\mu}g/ml$ in sulfamethoxazole and > $250{\mu}/ml$ in oxytetracycline. In general, the MIC of E coli isolates was higher than that of Salmonella spp isolates. Although variation in synergism or additivity of antibiotic combinations were demonstrated, ampicillin-gentamicin was the most efficacious combination both against E coli and Salmonella spp with the fluctuation of 7.7-77.5%. In the experiment of treatment efficacy in mice, the highest survival ratio(83.3%) after challenge with pathogenic E coli and Salmonella typhimurium was detected in the group treated with gentamicin.

The present study describes the effectiveness of egg yolk antibodies (IgY) against enteric colibacillosis and edema disease in piglets. The antibodies were gained from the egg yolk of hens immunized with k88, k99, 987p fimbrial adhesin and heat-labile toxin antigens of enterotoxigenic Escherichia coli (ETEC). Orally-administered egg yolk antibodies solution protected against experimental challenge with ETEC $K88^+$ and $k99^+$ strains in neonatal piglets and mice. In field trial, a total of 598 diarrheal piglets were orally treated with 3ml of antibody once a day to determine for the therapeutic effect. Of them, 582 (97.3%) piglets were recovered from diarrhea in 3 days. We also experimentally treated with the egg yolk antibodies twice a day for 5 consecutive days for 94 weaning piglets with edema disease for the determination of therapeutic effects. Seventy four piglets (78.7%) were recovered from clinical edema signs. Theses findings indicate that egg yolk antibodies against k88, k99, 987p and LT of ETEC are useful source of passive immunity for enteric colibacillosis and edema disease of piglets.
