This study was performed to identify the optimal timing for oocyte donor replacement during OPU procedure. OPU was carried out to collect oocytes from every donor at an interval of $3{\sim}4$ days (2 times a week). The collected oocytes were matured in vitro in TCM-199 supplemented with 10% FBS, 10 mg/ml of FSH and 1 mg/ml of estradiol for 24 h. After 24 h of exposure to sperm, the presumptive zygotes were cultured in CR1aa medium supplemented with 4 mg/ml of BSA for 3 days before being changed to CR1aa medium with 10% of FBS for another $3{\sim}4$ days. The mean numbers of retrieved oocytes were remained constantly up to 3 months ($6.0{\pm}0.5$, $6.2{\pm}0.7$, $5.2{\pm}0.6$), but significantly decreased at over 4 to 6 months ($3.7{\pm}0.5$, $2.8{\pm}0.4$, $1.2{\pm}0.2$) (p<0.05). The blastocyst development potential was also very similar rate from 1 to 3 months (37.2%, 40.4% and 44.6%), but significantly decreased from 4 to 6 months (24.8%, 29.3% and 28.6%, respectively) (p<0.05). The production of OPU derived embryos in periods of 1 to 3 months ($2.2{\pm}0.3$, $2.5{\pm}0.3$ and $2.3{\pm}0.4$) were significantly higher than those in 4 to 6 months ($0.9{\pm}0.2$, $0.8{\pm}0.2$ and $0.3{\pm}0.2$, respectively) (p<0.05). In conclusion, the efficient periods for the production of OPU derived embryos was until 4 months, twice per week to produce over 64 transferable embryos and then replace new donor after 3 months use. The best replacement time is 3 months and could be maximized production of OPU derived embryos.

In this study, we examined the number and motility of sperms, and also observed the changes in testes weight, and histological changes of several organs after 5 days of a continuous administration of dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin) of per oral administration of a herb drug extracts, which were administerated altermate days, to elucidate the effects of the a herb drug extracts on reproductive toxicity of dioxin. 1. The sperm numbers of dioxin-administered groups were 90.7$\pm$3.6~l18.5$\pm$3.6$\times$10/suup 6/$m\ell$ and 67.3$\pm$4.1~88.2$\pm$3.3$\times$10$^{6}$ $m\ell$ for 10~20 $\mu\textrm{g}$/kg and 30~40 $\mu\textrm{g}$/kg dosages of dioxin-administerated groups, respectively. Each dioxin-administered group showed prominently lower value than that of control group's which was 119.3$\pm$3.4~120.2$\pm$4.7 $\times$ 10$^{6.}$$m\ell$. 2. The sperm motility of each dioxin-administered group's also showed lower value than that of control group's which was 93.6$\pm$3.8~94.9$\pm$3.4%. The sperm motility of each dioxin-administerated group were 77.0$\pm$4.7~89.5$\pm$3.6% and 66.5$\pm$3.3 ~79.9$\pm$3.8% for 10~20 $\mu\textrm{g}$/kg and 30~40 $\mu\textrm{g}$/kg dosages of dioxin-administerated groups, respectively. 3. The sperm numbers of each group, which was administered a herb drug extracts, were 77.4$\pm$3.2~90.9$\pm$3.4$\times$10$^{6}$ $m\ell$, 78.0$\pm$3.3~105.0$\pm$4.2$\times$10$^{6}$ $m\ell$, 76.2$\pm$2.8~84.4$\pm$3.5$\times$10$^{6}$ $m\ell$ and 75.4$\pm$3.3~80.2$\pm$3.3$\times$10$^{6}$ $m\ell$ for extracts of green leaf, red ginseng, Kugija and Oume-administered groups respectively. And the sperm motility of each group were 63.4$\pm$3.8~77.0$\pm$4.0%, 65.5$\pm$4.1~87.4$\pm$3.8%, 64.3$\pm$4.2~69.8$\pm$4.2%, 66.3$\pm$3.9~66.0$\pm$4.0% for extracts of green leaf, red ginseng, Kugija and Oume extracts-administered groups, respectively. 4. The number and motility of sperm of control group were 119.3$\pm$3.4~120.2$\pm$4.7$\times$10$^{6}$ $m\ell$ and 93.0$\pm$3.5~96.1$\pm$3.5%, respectively. Red ginseng extracts- administered group seemed to be recovered than my other groups, and the green leaf extracts-administered group was shown to be the next. The Kugija and Oume extracts-administered groups didn't show to be recovered much. 5. Most a herb drug extracts-administered group except the red ginseng-administered group displayed prominently lower values of testes weights than that of control group's which was 0.15$\pm$0.01~0.16$\pm$0.01g. The red ginseng extracts-administered group seemed to be recovered conspicuously. 6. After 5 days of a continuous administration of 30 $\mu\textrm{g}$/kg dosage of dioxin followed by 3 weeks of per oral administration of green leaf, red ginseng, Kugija, or Oume extracts, histological findings showed that the liver, spleen, and testis of most a herb drug extracts-administered groups were damaged severely. By the way, the testes of red ginseng extracts-administered group seemed to recover compared to the other group's.ompared to the other group's.

This study was conducted to evaluate the inhibitory effects of exopolysaccharide(EPS) produced by Streptococcus thermophilus BODY1 on rotavirus(RV). EPS was isolated from a commercial lactic acid bacteria, Str. thermophilus BODY1. The results obtained were as follows : At 0.1% of EPS, inhibitory effects of EPS on the MA-104 cell using MTT assay were, $Wa\;51.58{\pm}8.08%,\;KU \;63.09{\pm}7.58%,\;S2\;51.23{\pm}5.43%,\;YO\; 51.45{\pm}5.67%,\;K-21\;52.84{\pm}5.49%,\;NCDV\;57.50{\pm}10.85%,\;UK\;51.64{\pm}4.74%,\;KK3\;54.53{\pm}8.44%,\;JBR\;58.67{\pm}7.51%,\;S97\;50.63{\pm}5.17%,\;OSU\;55.48{\pm}5.75%,\;and\;RRV\;54.36{\pm}8.72%$, respectively.

This study was carried out to investigate the general characteristics such as volume, sperm concentration, sperm motility, sperm abnormality on whole semen, RSP-S and RSP-T semen and fractional semen of small size dogs, and the effect of temperature and preservation time and cryoproservation on motility of whole and RSP-S and RSP-T semen. Multiple ejaculates were collected from small dogs by the digital manipulation of penis. 1. The volume per ejaculate semen, sperm of concentration and motility and abnormal sperm rate of 1st fractional semen were 0.65$\pm$0.09 $m\ell$, 4.52$\pm$0.35$\times$10$^{6}$ cells/$m\ell$, 15.64$\pm$3.85% and 5.50$\pm$0.62%. Also, 2nd fractional semen were 1.25$\pm$0.20$m\ell$, 3.35$\pm$0.48$\times$10$^{6}$ cells/$m\ell$, 96.25$\pm$4.65% and 4.24$\pm$0.46%. And 3rd fractional semen were 1.45$\pm$0.21$m\ell$, 3.55$\pm$0.52$\times$10$^{6}$ cells/$m\ell$, 92.82$\pm$4.24% and 4.66 $\pm$0.58%, respectively. 2. The sperm of concentration and motility and abnormal sperm rates of whole, RSP-S and RSP-T semen were 5.45$\pm$0.82$\times$10$^{6}$ cells/$m\ell$, 95.55 $\pm$4.65%, 4.58$\pm$0.45% and 4.82$\pm$0.36$\times$10$^{6}$ cells/$m\ell$, 90.10$\pm$3.42%, 6.48$\pm$0.68% and 4.55$\pm$0.45$\times$10$^{6}$ cells/$m\ell$, 93.25$\pm$3.85%, 4.82$\pm$0.58%, respectively. 3. The motility of whole, RSP-S and RSP-T semen were higher at 4$^{\circ}C$ than at 38$^{\circ}C$. When preservation temperature was at 4$^{\circ}C$, survival rates of RSP-S and RSP-T sperm were 97.54~6.25% at 1~72 hrs, 97.40~5.62% at 1~100 hrs, respectively. 4. The survival rates of slow and rapid frozen 2nd fraction, RSP-S and RSP-T semen were 67.3$\pm$4.45%, 88.8$\pm$4.46% and 46.4$\pm$3.84%, 74.4$\pm$4.20%, respectively. Survival rates was significantly higher in frozen RSP-S and RSP-T semen than that in control group(8.5$\pm$2.12%).

Background: Hemodilution after priming of the cardiopulmonary bypass is known to increase the possibility of bleeding and homologous transfusion in adult cardiac surgery. We investigated the effects of retrograde autologous priming (RAP) to see whether it would decrease postoperative bleeding and homologous transfusion. Material and Method: We retrospectively reviewed 34 patients wpho underwent RAP and 46 patients who did not. Retrograde autologous priming consisted of arterial lire drainage, venous reservoir and oxygenator drainage and venous line drainage. We compared the amount of priming solution and RAP volume, perioperative hematocrit, postoperative bleeding and transfusion requirements in the two groups. Resuit: Mean withdrawal volume in RAP group was 613.5$\pm$160.6 mL and initial priming volume was 1381.9$\pm$37.2 mL. Hemoatocrits ($\%$) in RAP and control groups were 25.0$\pm$3.7 vs 20.9$\pm$3.6 (5 minutes after CPB), 25.9$\pm$3.7 vs 22.5$\pm$3.6 (30 minutes after CPB), 25.9$\pm$3.4 vs 23.8$\pm$2.8 (60 minutes after CPB), 31.9$\pm$3.9 vs 31.5$\pm$4.5 (postoperative 1 hour), 32.4$\pm$4.4 vs 32.1$\pm$4.5 (postoperative 6 hours), 33.4$\pm$5.0 vs 31.7$\pm$5.1 (postoperative 1 day)[repeated measures ANOVA, p < 0.05]. Chest tube drainages (mL) in the two groups were 357.2$\pm$177.1 vs 411.7$\pm$279.5 (postoperative 6 hours), 599.4$\pm$145.6 vs 678.8$\pm$256.4 (postoperative 24 hours)[t-test, p < 0.05]. Homologous transfusion was performed in 7 out of 34 patients in RAP group (20.6$\%$), and 16 out of 46 (34.8$\%$) in control group (p < 0.05). Conclusion: This study suggests that the effects of reducing the priming volume during cardiopulmonary bypass may result in lesser bleeding and homologous transfusion. Retrograde autologous priming would be used to reduce postoperative bleeding and chance of transfusion after adult cardiac surgery.
