Oxygen consumption is a useful parameter for evaluating mammalian embryo quality, since individual bovine embryos was noninvasively quantified by scanning electrochemical microscopy (SECM). Recently, several approaches have been used to measure the oxygen consumption rates of individual embryos, but relationship between oxygen consumption and pregnancy rates of Hanwoo following embryo transfer has not yet been reported. In this study, we measured to investigate the correlation between oxygen consumption rate and pregnancy rates of Hanwoo embryo using a SECM. In addition to, the expression of pluripotent gene and anti-oxidant enzyme was determined using real-time PCR by extracting RNA according to the oxygen consumption of in vivo embryo. First, we found that the oxygen consumption significantly increased in blastocyst-stage embryos (blastocyst) compared to early blastocyst stage embryos, indicating that oxygen consumption reflects the embryo quality (Grade I). Oxygen consumption of blastocyst was measured using a SECM and total cell number of in vitro blastocyst was enumerated by counting cells stained by propidium iodide. The oxygen consumption or GI blastocysts were significantly higher than those of GII blastocysts ($10.2{\times}10^{15}/mols^{-1}$ versus $6.4{\times}10^{15}/mols^{-1}$, p<0.05). Total cell numbers of in vitro blastocysts were 74.8, 90.7 and 110.2 in the oxygen consumption of below 10.0, 10.0~12.0 and over $12.0{\sim}10^{15}/mols^{-1}$, respectively. Pregnant rate in recipient cow was 0, 60 and 80% in the transplantation of embryo with the oxygen consumption of below 10.0, 10.0~12.0 and over $12.0{\times}10^{15}/mols^{-1}$, respectively. GPX1 and SOD1 were significantly increased in over -10.0 group than below 10.0 groups but in catalase gene, there was no significant difference. On the other hand, In OCT-4 and Sox2, pluripotent gene, there was a significant difference (p<0.05) between the below-10.0 ($0.98{\pm}0.1$) and over 10.0 ($1.79{\pm}0.2$). In conclusion, these results suggest that measurement of oxygen consumption maybe help increase the pregnant rate of Hanwoo embryos.

Various herbal medicinal extracts were examined for the development of cosmetic products with anti-oxidative and anti-wrinkle activity. First, total polyphenol contents and DPPH radical scavenging activities of herbal medicinal extracts were measured. Most herbal samples, except for DW extracts of Portulaca oleracea, Caesalpinia sappan, Taraxacum platycarpum, Carthamus tinctorius, and 70% EtOH extracts of Taraxacum platycarpum and Carthamus tinctorius, showed DPPH radical scavenging activity over 80% at a concentration of $400{\mu}g/m{\ell}$. SOD-like antioxidant activity of DW extracts of Syzygium aromaticum, DW extracts of Eriobtrya japonica and 70% EtOH extracts of Sophora japonica was measured as 40%, 35% and 80%, respectively at a dry matter concentration of $50{\mu}g/m{\ell}$. In elastase inhibition assay, DW extracts of Lycium chinense ($50{\mu}g/m{\ell}$) and 70% EtOH extracts of Areca catechu ($50{\mu}g/m{\ell}$) showed 50% and 40% of inhibition, respectively. At a concentration of $1.250{\mu}g/m{\ell}$, DW extracts of Lycium chinense and 70% EtOH extracts of Areca catechu showed 10% and 30% of collagenase inhibition, respectively. Skin and lotion samples were prepared using the two herbal extracts of high anti-wrinkle activity: Lycium chinense extract and Areca catechu extract. The storage stability of skin and lotion containing each of the selected herbal extracts was evaluated. pH and viscosity were used as stability indicators for the stability test under different storage temperatures and freeze-thaw cycle conditions. The skin and lotion containing each of DW extract of Lycium chinense and 70% EtOH extract of Areca catechu was showed high pH and viscosity stability. The skin and lotion containing DW extracts of Lycium chinense showed relatively higher stability than the skin and lotion containing 70% EtOH extract of Areca catechu, at cycle chamber and freeze-thaw conditions. In summary, these results indicated that cosmetics containing DW extract of Lycium chinense were relatively stable, and this herbal extract could be used as a stable functional cosmetic material.

This study was to investigate the effect of flavonoid treatment on in vitro development of bovine somatic cell nuclear transfer (SCNT) embryos, and their pregnancy and delivery rate after embryo transfer into recipient. In experiment 1, to optimize the flavonoid concentration, parthenogenetic day 2 ($\geq$ 2-cell) embryos were cultured in 0 (control), 1, 10 and $20\;{\mu}M$ flavonoid for 6 days. In the results, in vitro development rate was the highest in $10\;{\mu}M$ flavonoid group (57.1%) among treatment groups (control, 49.5%; $1\;{\mu}M$, 54.2%; $20\;{\mu}M$, 37.5%), and numbers of total and ICM cells were significantly (p<0.05) higher in $10\;{\mu}M$ flavonoid group than other groups. We found that $10\;{\mu}M$ flavonoid treatment can significantly (p<0.05) decrease the apoptotic index and derive high expression of anti-oxidant, anti-apoptotic, cell growth and development marker genes such as Mn-SOD, Survivin, Bax inhibitor, Glut-5, In-tau, compared to control group. In experiment 2, to produce the cloned Jeju Black Cattle, beef quality index grade 1 bull somatic cells were transferred into enucleated bovine MII oocytes and reconstructed embryos were cultured in $10\;{\mu}M$ flavonoid added medium. When the in vitro produced day 7 or 8 SCNT blastocysts were transferred into a number of recipients, $10\;{\mu}M$ flavonoid treatment group presented higher pregnancy rate (10.2%, 6/59) than control group (5.9%, 2/34). Total three cloned Jeju Black calves were born. Also, two cloned calves in $10\;{\mu}M$ flavonoid group were born and both were all healthy at present, while the one cloned calf born in control group was dead one month after birth. In addition, when the result of short tandem repeat marker analysis of each cloned calf was investigated, microsatellite loci of 11 numbers matched genotype between donor cell and cloned calf tissue. These results demonstrated that the flavonoid addition in culture medium may have beneficial effects on in vitro and in vivo developmental capacity of SCNT embryos and pregnancy rate.

표고버섯의 열수 가용성 다당류(PS)와 간 장해물질이며 발암성을 갖는 butter yellow를 흰쥐의 식이에 6주간 투여하여 혈장과 간의 효소활성 및 과산화지질의 함량을 측정한 결과는 다음과 같다. 1. 혈장 중 GOT 활성은 better yellow 첨가군(BO군)보다 PS의 투여군(BP군 : BO+PS)이 비교적 낮은 수준을 나타내었으며 ${\gamma}$-GTP와 GPT 활성에서도 BO군에 비하여 BP군에서 유의하게 낮은 활성을 나타냈다. 2. 간장 중 glutathion peroxidase, catalase 및 lactate dephdregenase 활성 또한 기초식이군(NO군)에 PS를 토여한 군(NP군)은 NO군과 유의한 차이가 없었으나 BP군은 BO군에 비하여 유의하게 낮은 수준이었다. SOD활성은 각 군간에 유사한 수치로 유의적인 차리를 보이지 않았다. 3. 간장의 microsomal 분획분 및 cytosol 분획분 중의 glutathione S-transferase 활성도는 BP군이 BO군보다 유의하게 낮은 수준을 보였으나 better yellow를 첨가하지 않은 NO군에 비하여 상당히 높은 수준을 나타내었다. 4. 간장 내 glutathione과 malondialdehyde의 함량 또한 PS의 투여로 생성이 저하되는 것으로 나타났다. 이상의 결과를 보아 표고버섯의 열수 추출물은 생체조직의 지질의 과산화를 방지하므로써 better yellow에 의한 간장장애의 치료 또는 독성을 완화하는 효과가 있는 것으로 사료된다.

Met과 Se의 공급수준이 흰쥐의 알코올대사 효소계에 미치는 영향을 관찰하고자, Sprague-Dawley종의 웅성 흰쥐에게 Se 무첨가 및 정상공급식이 (0, 0.45mg/kg diet)에 Met(0, 3, 9g/kg diet)을 투여한 후 5주와 10주간 사육하여 간조직중의 알코올 대사효소와 항산화 방어 효소계 활성도를 관찰하였다. 알코올은 aldehyde dehydrogenase와 microsomal ethanol oxidizing system 활성도를 유의적으로 증가시켰으며, Met과 Se의 동시 결핍시 현저하게 감소하였고 Met과 Se의 동시 공급군의 경우 알코올 투여기간이 길수록 그 활성이 유의적으로 증가하였다. Aldehyde dehydrogenase 활성도는 알코올 투여로 감소하였으며 Met과 Se 동시 결핍군에서는 현저한 감소를 나타내었고, 사육기간이 길수록 그 활성이 유의적으로 감소되었다. Cytochrome P-450과 xanthine oxidase 활성도는 알코올 투여 시 유의적으로 증가되었는데 Se 결핍시 Met 결핍군과 과량공급군에서 그 증가가 현저하였으며, 5주 실험군에 비해 10주 실험군에서 유의적인 증가를 나타내었다. Superoxide dismutase, catalase 및 glutathione S-transferase 활성도는 알코올 투여시 증가되었으며, superoxide dismutase와 catalase 활성도는 알코올 투여기간이 길수록 유의적인 증가를 나타내었다. 알코올 투여시 glutathione peroxidas 활성도는 감소되었으며, Met 수준이 높을수록 증가하는 경향이었고, Met과 Se 동시 결핍시 현저하게 감소하였다. 이상의 결과에서 식이성 Met과 Se은 동물의 성장 및 정상적 대사유지에 필수적인 영양소로서 알코올 투여 시 Met과 Se 첨가에 따라 알코올대사 효소활성도와 항산화 방어효소 활성도의 변화를 유도할 수 있었다. 또한 식이 kg당 3g의 Met과 0.45mg의 Se 동시 공급시 원활한 알코올대사를 유도하여 알코올성 간손상을 가장 효율적으로 경감시킬 수 있는 것으로 나타났다.

Injinho-tang(IJ) has been used for the treatment of hepatobiliary diseases. This study was performed to observe the effect of IJ extract on the hepatocellular carcinogenesis and hepatic cirrhosis induced by Diethylnitrosamine(DENA) and $CCl_4$ in Rats. Experimental groups were divided into two ; 8th and 12th week group, and subdivided into four; normal group(Nor), hepatocellular cancer and hepatic cirrhosis inducing control group(Con), and IJ extract 260mg/kg/day(IJA) or 520mg/kg/day(IJB) administered groups to Con. The results obtained are as follows: The body weight was decreased in the Con, IJA and IJB compared with the Nor from the 2nd week to the 12th week. The weight of liver and the weight of liver/100g body weight were decreased significantly in Con, IJA and IJB compared with the Nor. The activities of aspartate aminotransferase(AST) and alanine aminotransferase(ALT) were significantly increased in the Con compared with Nor, but decreased in the IJA and IJB compared with Con from the 8th week group. The activities of alkaline phosphatase(ALP), lactacte dehydrogenase (LDH) and alpha fetoprotein(AFP) were increased significantly in the Con compared with Nor, but decreased in the IJA and IJB compared with Con. The activities of superoxide dismutase(SOD) were decreased in the IJA and IJB compared with Con, but the activities of catalase were increased in the IJA and IJB compared with Con. According to the light and electron microscopical observation, IJA and IJB improved the morphological and histopathological changes of the liver injured by DENA and $CCl_4$. The number of hepatic p53 positive cells was decreased in the IJA and IJB compared with Con. These results suggest that administration of IJ extract suppress or retard DENA and $CCl_4$-induced hepatocelluar carcinogenesis and hepatic cirrhosis in rats.
