The present study was conducted to investigate the effects of dietary supplementation of Codonopsis pilosula extract powder (CEP) on the reproductive performance in sows. A total of 20 pregnant sows were randomly assigned to two dietary treatments, which was given a corn and soybean meal-based diets containing 0 or 5 g/kg of the CEP from 40 days prepartum to weaning (25 days postpartum). The serum immunoglobulin G (IgG) concentration of sow (p<0.01) and piglets (p<0.05) was significantly increased by the feeding of CEP. And we also demonstrated that the coefficient of correlation between the colostrum and serum indicates a significant positive correlation on IgG. The stillbirth of sows and mortality rate during suckling periods were slightly lower in CEP feeding group than control, but there is no significant difference. In conclusion, our results suggest that the dietary supplementation of CEP increases the humoral immunity in both of sows and piglets, and it might contribute to improve the reproductive performance of sows. Further, additory studies are necessary on the immunomodulatory mechanism of CEP components.

Aspirin and prednisolone have been used alone or in combination in the treatment of rheumatic diseases. We have investigated the significance of the difference of the anti-inflammatory and antipyretic activities between single and concurrent administration of aspirin and prednisolone in rats by using carrageenan as a phlogistic agent and brewer's yeast as a fever inducing agent. When prednisolone (9mg/kg) and aspirin (24mg/kg) were administered orally alone or in combination, both of the concurrent and single adminstration inhibited highly significantly the swelling of rat paw and the concurrent adminstraiton of aspirin and prednisolone showed the significantly higher inhibitory effects than aspirin single adminstration did, whereas there were not any significant differences between the prednisolone single adminstration and combined adminstration. The combined drug of aspirin and prednisolone marketed in Korea contains 148mg of aspirin and 1.15mg of prednisolone in a tablet. Therefore, we examined the anti-inflammatory and antipyretic activities of aspirin (150mg/kg), prednisolone (1mg/kg) and their combination. In anti-inflammatory effects, both of the concurrent and single administration inhibited higly significantly the swelling of rat paw, and the concurrent adminstration exhibited the significantly higher inhibitory effects than aspirin or prednisolon alone did. In antipyretic effects both of the concurrent and the single adminstration reduced significantly the brewer's yeast-induced fever. The effect of concurrent administration was greater than that of prednisolone single adminstration, whereas the effect of aspirin single adminstration was similar to that of combination. The results suggest that the anti-inflammatory and antipyretic effects are intensified by the concurrent adminstration of aspirin and prednisolone, but the antipyretic effects of enough doses of aspirin (150mg/kg) is comparable to that of the combination preparation.

Potate tubers with slver scurf lesions were collected from the cold storage at Pyungchang, Kangwon province in Korea. The causal agent of the silver scurf was identified as Helminthosporium solani by mycological characteristics of conidia and conidiophores. Pathogenicity of the fungus was confirmed by artificial inoculation on the potato tuber. This is the first report of potato silver scarf by Helminthosporium solani in Korea.

국내 전통식품 중에 함유되어 있는 ochratoxin A를 검출할 수 있는 신속, 정확한 분석방법을 확립하고자 immunoaffinity column과 $C_{18}$ Sep-Pak cartridge를 비교 후 분리도와 회수율이 우수한 immunoaffinity column으로 전처리 방법을 사용하였으며 HPLC 검출한계는 $0.5{\mu}g/kg$로 나타났다. 오염도조사를 위하여 시판되는 장류(고추장, 된장, 간장 각 20건) 60건을 수거하여 분석한 결과 고추장 3건, 된장 2건, 간장 1건에서 $0.5-1.3{\mu}g/kg$ 수준으로 검출되었으며 수거된 선식 40건에서는 ochratoxin A가 검출한계이하 수준이었다. 이는 일부 외국의 규격치인 $5-50{\mu}g/kg$와 비교해 볼 때 낮은 수준이었다.

This study aims to examine the operating status of the Farmer's Health Center Project and the validity of its business using the benefit-cost analysis. As the pilot project of the Rural Development Adminstration from 1996, a total of 884 Farmer's Health Centers were established until 2004. Internal information of the RDA management unit was used for the analysis. A questionnaire with an interview was also performed with 70 over 468 Centers that had been established from 2001 to 2004. Results were as follows. 1) The Center was mainly used by elderly over 60 years, which took 71.4%. Winter was the most popular season for visiting. 2) Approximately 71% of the manager of the Center pointed out the deficiency of fuel cost as the most difficulty in operating the Center. 3) Users were moderately satisfied with facility and the effect of its use, which took 3.5 point over 5 scale. 4) For the cost-benefit analysis on the Centers, both 5% of social discount rate and 15 years of use term were assumed. Subsequently, the Net Present Value was 3,134 million won, which certified the validity of the business.

For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of spermatozoa indicates active metabolism, membrane integrity and fertilizing capacity. Estrogen receptors 2(ESR2) is involved in estrogen related apoptosis in cell cycle spermatogenesis, but their functions have not been confirmed in pig until now. Therefore, this study was conducted to analyze their association with sperm motility and kinematic characteristics. DNA samples from 105 Duroc pigs with records of semen motility and kinematic characteristics [Total motile spermatozoa (MOT), Curvilinear velocity(VCL), Straight-line velocity(VSL), the ratio between VSL and VCL(LIN), Amplitude of Lateral Head displacement(ALH)] were analyzed. A SNP in coding region of ESR2 g.35547A > G in exon 5 was associated with MOT (p < 0.05) in Duroc population. Therefore, we suggest that the porcine ESR2 gene may be used as a molecular marker for Duroc boar semen quality, although its functional effects were not defined yet. These results might shed new light on the roles of ESR2 in spermatogenesis as candidate gene for boar fertility, but still the lack of association across populations should be considered.
