The present study was conducted to characterize maternal antibody status which haemagglutination inhibition(HI) titers against canine parvovirus(CPV) in the 15 puppies delivered from 3 dams. The range of HI titers of 5 puppies delivered from a mother dog(A) with HI titer of 1 : 1,024 were 1 : 16~1 : 64 at 1 day old before suckling, 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 512~1 : 2,048 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 128~l : 512 at 3 weeks old, 1 : 128~l : 256 at 4 weeks old, 1 : 32~1 : 128 at 5 weeks old, 1 : 16~1 : 64 at 6 weeks old, 1 : 16~1 : 64 at 7 weeks old, and 1 : 16~l : 32 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 days and 80 days old puppies, 1 : 8~l : 32 at 9 weeks old, 1 :16~1 : 128 at 10 weeks old, 1 : 32~1 : 256 at 11 weeks old, 1 : 16~1 : 256 at 12 weeks old, 1 : 128~1 : 256 at 13 weeks old, 1 : 64~l : 512 at 14 weeks old, and 1 : 128~1 : 512 at 15 weeks old. The HI titers of 3 puppies delivered from a mother dog(B) with HI titer of 1 : 512 were 1 : 16 at 1 day old before suckling, 1 : 256~1 : 512 at 2 days old after suckling, 1 : 512 at 1 week old, 1 : 128~1 : 256 at 2 weeks old, 1 : 64~1 : 128 at 3 weeks old, 1 : 64~1 : 128 at 4 weeks old, 1 : 128 at 5 weeks old, 1 : 64~1 : 128 at 6 weeks old, 1 : 16 at 7 weeks old, and 1 : 8 at 8 weeks old. After vaccination with DHPPL to canine parvovirus in 60 day and 80 days old puppies, < : 8~l : 8 at 9 weeks old, < : 8 ~1 : 16 at 10 weeksold, 1 : 64~1 : 128 at 11 weeks old, and 1 : 256~1 : 512 at 12 weeks old. The HI titers of 7 puppies delivered from mother dog(C) with Hl titer 1 : 1,024 were 1 : 512~1 : 1,024 at 2 days old after suckling, 1 : 256~1 : 1,024 at 1 week old, 1 : 256~l : 1,024 at 2 weeks old, 1 : 64~1 : 512 at 3 weeks old, 1 : 64~1 : 512 at 4weeks old, 1 : 8~l : 64 at 5 weeks old, 1 : 8~1 : 64 at 6weeks old, 1 : 8~1 : 32 at 7 weeks old, and < : 8~1 : 8 at 8 weeks old. Antibody to CPV was transferred mainly from mother to progeny through the colostrum and the transferred maternal antibody was in proportion to the HI titer of the mother As the HI titer of maternal antibody in puppies was low, puppies have a rapid immune response and a massive rise in HI titer to vaccination against CPV compared with puppies haying high level of maternal antibody.

The purpose of this study was to investigate effects of moxibustion at combined acupoints on sex and age in rats. This study measured the effects of moxibustion on small intestinal motility in rats. Cauterizing with moxa was applied 5 times to the acupoints on SI8, LI11 SP9 and ST36 under enflurane anesthesia in the groups divided with sex and age. In single acupoint groups, cauterizing with moxa on ST36 increased in all of sex and age groups. The SP9 group with 5, 6 weeks in female and 5, 8 weeks in male, the SI8 group with 5, 7 weeks in female and only 7 weeks in male, the LI11 group with only 5, 6, 7 weeks in female and only 7 weeks in male showed increasing on small intestinal motility. In combined acupoints groups, the SI8+SP9 group with 7 weeks in female and 5, 6, 8 weeks in male, the SI8+ST36 group with 5, 6 weeks in female and 8 weeks in male, the LI11+SP9 group with 5, 6 weeks in female and 6 weeks in male, the LI11+ST36 group with 5 weeks in female and 5, 6, 7 weeks in male showed increasing respectively. Although these different according to the sex and age in rats do not have a established tendency, the results suggested that the effects of combined acupoints of cauterizing with moxa have relation with individuality.

Objective : This study was designed to determine whether manual acupuncture therapy is effective for symptoms of patients with idiopathic Parkinson's disease. Methods : Nineteen patients consecutively enrolled in this study. The subjects were divided into two groups : the first group (n=12) discontinued antiparkinsonian drug treatment, the second group (n=7) continued antiparkinsonian drug treatment Acupuncture therapy was performed twice a week for 8 weeks. In the first group, the acupuncture was performed after 2 weeks of drug wash-out period. The patient's symptoms were assessed at pre-treatment, 4 weeks and 8 weeks after the acupuncture by unified Parkinson's disease rating scale (UPDRS), modified Hoehn-Yahr (H-Y) stage, Schwab & England activity of daily living and Freezing of Gait Questionnaire(FOGQ). Results : In the first group that discontinued. antiparkinsonian drug treatment, the total UPDRS scores were significantly improved after 4 weeks (p=0.0l4) and after 8 weeks (p=0.049) compared to the pre-treatment. Particularly, the scores of UPDRS III were significantly improved after 8 weeks (p=0.032). In the second group that continued antiparkinsonian drug treatment, the total UPDRS scores were significantly improved after 4 weeks (p=0.027) and after 8 weeks (p=0.018). Particularly, the scores of UPDRS II were significantly improved after 4 weeks (p=0.042) and after 8 weeks (p=0.043), and UPDRS IV were significantly improved after 8 weeks (p=0.043). The scores of ADL were significantly improved after 8 weeks (p=0.046). Conclusion : This study suggests that manual acupuncture therapy is effective for the improvement of certain symptoms in patients with idiopathic Parkinson's disease.

The considerable researches have been done on the change,1 associated with age in the blood picture of domestic animals, but a survey has not been of the blood picture in Thoroughbred fears in Korea. Therefore, the purpose of this study is to outline the range of values in clinically not\\\\`- mal Thoroughbred foals. Some blood chemical parameters from 3 days to 8 weeks of age were exam-ined to obtain normal values in Thoroughbred foal7. Blood samples were obtained from the jugular vein in 11 Thoroughbred foals and collected at 3 days, and at 1,2,4 and 8 weeks of age, respectively. The results obtained ill this study were summarized as follows: The packed cell volume (PCV) at 4 weeks of age was significantly lower than that at 3 days of age (P<0.01) and that al 2 and 8 weeks of age were straightly lower than that at 3 days of age (P<0.05). The total protein (TP) at 8 weeks of age was higher than that at 3 days, 1 and 2 weeks of age (P<0.05). The activity of aspartate ami-notransferase (AST) at 2,4 and 8 weeks of age were significantly higher than that at 3 days of age (P<0.01). The total bilirnbin showed a tendency to decrease gradually according to the weeks and that at 2,4 and 8 weeks of age were significantly lower than that at 3 days of age (P<0.01). The BUN at 1 and 8 weeks of ago were lower than that at 3 days of age (P<0.05). The concentration of Ca at 1 week of alee was higher than that at 3 days of age (P<0.05). The vitamin A and vitamin E showed a tendency to decrease gradually from 3 days to 4 weeks of age and increased slightly at 8 weeks of age.

Sixteen crosses from two strains of White Cornish and White Plymouth Rock were reared seperately on floors and abdominal fat was measured every two weeks interval from two weeks to twelve weeks of age. The abdominal fat weights surgically removed were slightly heavier in female than male. Estimates of general combining ability variances of body weight showed significant at all weeks of age in both sexes but those of abdominal fat weight were significant at 2, 8, 10 and 12 weeks of age in female and 2, 6 and 12 weeks of age in male. In percentage of abdominal fat to body weight, the significant differences were observed at 10 and 12 weeks of age only in female. The specific combining ability variances were significant at 4, 6, 10 and 12 weeks of age in female and 4, 8 and 12 weeks of age in male in body weight. In abdominal fat weight, there were significant differences at 4, 8, 10 and 12 weeks of age in female but no significant differences in male. The specific combining ability variances of percentage of abdominal fat to body weight showed significant differences at 4 and 8 weeks of age in female but no significant difference in male.

PURPOSE. The purpose of this study was to compare the new bone formation capability of zirconia with those of other synthetic bone grafts. MATERIALS AND METHODS. Twelve rabbits were used and four 6-mm diameter transcortical defects were formed on each calvaria. Each defect was filled with Osteon II (Os), Tigran PTG (Ti), and zirconia (Zi) bone grafts. For the control group, the defects were left unfilled. The rabbits were sacrificed at 2, 4, and 8 weeks. Specimens were analyzed through micro computed tomography (CT) and histomorphometric analysis. RESULTS. The Ti and Zi groups showed significant differences in the amount of newly formed bone between 2 and 4 weeks and between 2 and 8 weeks (P<.05). The measurements of total bone using micro CT showed significant differences between the Os and Ti groups and between the Os and Zi groups at 2 and 8 weeks (P<.05). Comparing by week in each group, the Ti group showed a significant difference between 4 and 8 weeks. Histomorphometric analysis also showed significant differences in new bone formation between the control group and the experimental groups at 2, 4, and 8 weeks (P<.05). In the comparison of newly formed bone, significant differences were observed between 2 and 4 weeks and between 2 and 8 weeks (P<.05) in all groups. CONCLUSION. Zirconia bone graft material showed satisfactory results in new bone formation and zirconia could be used as a new synthetic bone graft material.
