한우 종모우에 있어 정액 채취시 승가 조건(의빈우 혹은 의빈대)이 정액성상에 미치는 영향을 구명하기 위하여 의빈우 승가 종모우 21두, 의빈대승가 종모우 9두 등 보증 종모우 30두를 공시하여 연구하였다. 정액은 $3{\sim}6$일 간격으로 채취하였으며 채취 당일 1시간 간격으로 총 2회 정액 채취하여 6개월간 정액성상을 조사하였다. 의빈대 승가 종모우가 의빈우 승가 종모우보다 1차 및 2차 정자농도에 있어 유의적으로 높아(p<0.05) 1차 및 2차 총 정자수에서도 많았으며 특히 l차 총 정자수는 유의적으로 많게 나타났다(p<0.05). 종모우 승 가 조건(의빈대, 의빈우)에 상관없이 5일 간격으로 정액 채취시가 정액량이 많아(p<0.05) 총 정자수가 많았으며 의빈대를 이용하여 5일 간격으로 정액 채취시가 총 정자수가 다른 모든 처리군보다 많았다. 의빈대 승가 종모우는 $4{\sim}5$세에서 총 정자 수가 높게 나타났으며 의빈우 승가 종모우는 $6{\sim}7$세에서 총 정자수가 높게 나타났다(p<0.05). 이러한 결과로 미루어 볼 때 한우 종모우에서 의빈대를 이용하여 정액을 채취하는 것이 의빈우를 이용 할 때 보다 정액 생산성이 좋을 것으로 사료된다.

Objectives : The purpose of this study was to examine the effects of Auricular acupressure with semen sinapis in obese children over a specific period of time. Methods : The study subjects included 27 obese children who were evaluated as such using Broca's Index at an elementary school located in M city. The data was collected throughout March 2, to May 31, 2005. In order to collect data, as a pre-test, characteristics of obesity and general characteristics were examined. Experimental treatments were used on Shinmun, Kijeom, Wijeom, Bijeom and Naebunbijeom. Among the auricular spots, one pill of semen sinapis was placed and pressed for five seconds at a time with exerted force and the subjects endured pain. This procedure was conducted ten tunes every morning, noon and evening for a period of six weeks. As a post-test, the degree of obesity were examined two weeks, four weeks and six weeks after acupressure had been applied. The data was collected and analysed using the SPSS/WIN 10.0 program by number, percentage, mean standard deviation, and Repeated Measure ANOVA. Result : The first hypothesis that 'The obesity of the children who had auricular acupressure with semen sinapis will show no difference over time' (two weeks, four weeks and six weeks after acupressure had been applied) was rejected(p=.000). A statistically significant difference in the obesity of the children who had auricular acupressure with semen sinapis was shown over time. The children's obesity degree reduced from 35.85% before auricular acupressure with semen sinapis to 28.67% six weeks after acupressure. Thus after six weeks of acupressure the relative degrees of obesity were reduced by 7.18%. Conclusion : Bases on the above results, it can be determined that auricular acupressure with semen sinapis can be used as an effective method of treatment in Korea, for reducing degrees of obesity in children.

본 연구는 Duroc 종모돈의 정액성상, 동결-융해후의 정자생존성 및 혈청 중 테스토스테론의 농도에 미치는 영향을 봄 (3~5월)과 여름 (6~8월)으로 나누어 실시한 바, 그 얻어진 결과는 다음과 같았다. 1. Duroc 종모돈의 정액량, pH, 정자농도는 봄과 여름철에 큰 차이가 없었다. 2. 봄철 및 여름철의 전체 정액량, 정자농후부분 그리고 정자희박부분에서 봄과 여름간의 차이는 나타나지 않았다. 3. 원정액 정자에서는 운동성 및 정상첨체에서 봄과 여름철간에 차이가 없었다. 그러나 동결-융해정자의 운동성 및 정상첨체는 봄철의 종모돈에서 생산한 정자가 여름철의 종모돈에서 생산한 정자보다 우수하였다. 4. 듀록 종모돈의 혈청 중 테스토스테론의 농도 변화는 봄과 여름에 각각 2.15 ng/$m\ell$과 0.65 ng/$m\ell$으로, 봄철 테스토스테론의 농도가 여름철의 농도 보다 높았다(P＜0.05). 5. 이상의 결과를 종합해 보면, 듀록 종모돈에 있어 정자의 내동성은 혈청 중 테스토스테른의 농도가 높을수록 우수한 것으로 나타났다.

Semen characteristics were examined to find the deterioration of the percentage of live spermatozoa with intact acrosome during hot season using 5 Holstein bulls located in Shirnizu-cho Hokkaido Japan. Spermatozoal viability and acrosomal status were observed simultaneously with triple-stain technique for each spermatozoon. Spermatozoa were divided in four categories (live spermatozoa with intact acrosome, live spermatozoa without intact acrosome, dead spermatozoa with intact acrosome and dead spermatozoa without intact acrosome). Bull and collection month had significant effects on semen characteristics (p < 0.01). The percentage of live spermatozoa with intact acrosome and the percentage of live spermatozoa had the lowest least squares mean by collection month in August (72.7% and 76.7%). These two characteristics indicated the obvious deterioration during hot season. But the fluctuation of these two characteristics were not parallel and the differences between the two characteristics were largest during July to September. The present results indicate the necessity for the simultaneous determination of viability and acrosomal status of each Holstein bull's spermatozoa in order to keep fertility above an acceptable minimum level during hot season.

This study was carried out to investigate the effects of season influencing semen characteristics, frozen-thawed sperm viability and testosterone concentration in Duroc boars. There were no significant differences in the semen volume and sperm concentration of Duroc boars among spring, summer, autumn and winter. However, the pH of sperm-rich and sperm-poor fractions in autumn and winter season was higher than in spring and summer season in Duroc boars. Sperm motility and normal acrosome of raw semen in Duroc boars did not differ significantly among spring, summer, autumn and winter. However, motility and normal acrosome of frozen-thawed sperm were higher in spring season than in summer, autumn and winter. Serum testosterone concentrations in Duroc were higher in spring than summer, autumn and winter. In conclusion, when serum testosterone concentrations were higher in seasons, frozen-thawed sperm viability in Duroc boars were higher.

Prostate cancer is one of the most common non-skin cancers in men. Armeniacae Amarum Semen has traditionally been used for the treatment of inflammation diseases, leprosy, leucoderma, and tumors. Apoptosis, which is also known as programmed cell death, is an important mechanism in cancer treatment.Objectives : We observed whether an aqueous extract of Armeniacae Amarum Semen induces apoptotic cell death in human DU145 prostate cancer cells.Methods : We treated DU145 cells with Armeniacae Amarum Semen extract and investigated characteristics of apoptosis. And investigated whether treated with Armeniacae Amarum Semen extract increased Bax mRNA expression, Bcl-2 mRNA expression, caspase-3 enzyme activity and their protein level.Results : We have shown that Armeniacae Amarum Semen extract can induce apoptotic cell death in human DU145 prostate cancer cells by caspase-3 activation through the down-regulation on Bcl-2 expression and the up-regulation on Bax expression.Conclusions : It can be expected that an aqueous extract of Armeniacae Amarum Semen may offer a valuable means for the treatment of prostate cancers.

This study investigated the effects of L-carnitine (LC) and nicotinic acid (NA) on sperm viability during liquid storage at $18^{\circ}C$ in miniature pigs. $10{\mu}M$ LC and 30 mM NA, combined LC and NA (LN) were treated in fresh semen for 3, 7, and 10 days. In results, sperm survival increased in NA- and LN-treated semen on 7 and 10 days (p<0.05), mitochondrial integrity of live sperm increased in LN-treated semen on 7 days (p<0.05), but not NA-treated semen. In addition, we examined the acrosome reaction of sperm in miniature pigs. LC and NA did not influence on acrosome reaction of boar sperm. In conclusion, LC and NA effectively maintained the viability and quality of sperm during long-term storage in miniature pigs, suggesting that the combined LN may be useful for improving the semen extender for long-term liquid storage in pigs.
