This study was carried out to investigate the general characteristics such as semen volume, pH, sperm motility and sperm concentration of the semen collected from Korean Jindo dogs by the mothod of Digital manipulation of penis, and the effect of temperature and preservation time on motility of fresh semen. Multiple ejaculates were collected from four male Korean Jindo dogs. The results obtained in this experiment were as follows : 1. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction and the small volume of third fraction from the ejaculate were 3.29ml, 6.30, 96.70% and 1.64$\times$108 cells/ml, respectively. 2. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the first fraction from the ejaculate were 1.16ml, 6.10, 6.67% and 5.07$\times$105cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction from the ejaculate were 2.30ml, 6.33, 97.66% and 1.92$\times$108cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the third fraction from the ejaculate were 3.24ml, 6.51, 93.33% and 3.13$\times$107cells/ml. 3. Motility of fresh semen during preservation were higher at 17$^{\circ}C$ than at 5$^{\circ}C$ or 36$^{\circ}C$. When preservation temeprature was 17$^{\circ}C$, motility were 95.75% at 1 h, 90.00% at 6 h, 84.25% at 12 h, 68.00% at 18 h, 36.25% at 24 h and 28.75% at 30 h, respectively.

In the advanced age, cardiovascular disease is more serious than any other disease. Especially, the thrombus causes the serious disease like apoplexia, carebri and myocardial infarction. Thrombosis is caused by the injury of endothelium and the alterations in normal blood flow. To investigate activities of Carthamus tinctorius L. Semen butanol fraction for blood coagulation system, endotoxin (4000EU/kg) was injected (i..v) to rats at 1hr after administration of Carthamus tinctorius L. Semen butanole fraction (500 mg/kg, p.o.). Carthamus tinctorius L. Semen butanol fraction was found to have antiplatelet activity in vitro. In vivo it showed a delay of blood clotting time, and prothrombin time, and reduction of fibrinogen and FDP It also increased SOD activity, and decreased MDA content. These results suggest that the antithrombosis effect of Carthamus tinctorius L. Semen butanol frac tion results from suppressive activity for a blood coagulation system and antioxidative activity.

In a preliminary screening of plant extracts for the antigastritic and anti- Helicobacter pylori (H. pylori) actions in rats, the ethanol extract of Amomi Semen (AS) showed positive activity in HCl Ethanol-induced gastric lesions and H. pylori. Among the systematic fractions of hexane, chloroform, butanol and water, the most potent butanol fraction significantly reduced HCl, Ethanol-induced gastric lesions at the oral dose of 350 mg/kg. Also butanol fraction has an inhibitory effect on the growth of H. pylori $(MIC=1.43\;{\mu}g/mL)$. In pylorus ligated rats, butanol fraction showed decrease in the volume of gastric secretion and acid output, of which effects were stronger in other fractions. We isolated 6 subfractions by column chromatography. The protective effects of 6 subfractions of Amomi Semen were also significant in the HCl, Ethanol induced gastric lesion model. These results might suggest that they had inhibitory action in gastric lesion through inhibition of gastric acid secretion. Butanol fraction of AS can be applied as treatment of H. pylori. Butano fractions and ethanol extract of AS was carried out or the development of a new gastroprotective supplementary product.

This study was carried out to investigate the general characteristics of semen such as semen volume, pH, sperm motility and sperm concentration of the semen collected from Shih Tzu dogs (age of 24 to 48 months, weight of 4 to 8 kg) by using the method of digital manipulation of the penis. The effect of preservation temperature and time on motility of fresh semen was also investigated in the present study. Semen was collected for 16 times from 4 male Shih Tzu dogs by multiple ejaculations (four times ejaculation per dog). The average of semen volume, semen pH, sperm motility and sperm concentration of the second fraction containing small volume of the initial third fraction per ejaculation were $2.11{\pm}0.31$ ml, $6.25{\pm}0.07$, $97.59{\pm}1.03%$ and $2.05{\pm}0.14{\times}10^8$ cells/ml, respectively. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the first fraction from the ejaculation were $1.12{\pm}0.15$ ml, $5.99{\pm}0.14$, $16.09{\pm}6.18%$ and $5.16{\pm}2.03{\times}10^5$ cells/ml, respectively. Those of second fraction were $2.07{\pm}0.29$ ml, $6.36{\pm}0.13$, $97.31{\pm}1.36%$ and $2.15{\pm}0.30{\times}10^8$ cells/ml, respectively. Those of third fraction were $2.60{\pm}0.29$ ml, $6.63{\pm}0.08$, $95.72{\pm}1.61%$ and $6.03{\pm}1.83{\times}10^7$ cells/ml, respectively. Sperm motility was significantly higher at $17^{\circ}C$ preservation temperature than at $5^{\circ}C$ or $36^{\circ}C$ during preservation period except 1 h preservation (P<0.05). When preservation temperature was $17^{\circ}C$, sperm motility was $96.69{\pm}1.49%$ at 1 h, $91.38{\pm}1.90%$ at 6 h, $88.38{\pm}2.34%$ at 12 h, $78.13{\pm}4.58%$ at 18 h, $58.44{\pm}8.57%$ at 24 h and $29.56{\pm}5.06%$ at 30 h, respectively.

Wound healing is a complex process that includes inflammation, granulation tissue formation, re-epithelialization, and remodeling. We reported previously that BuOH fraction from Hydnocarpi Semen (HS) crude extract exhibited wound healing activity in animal ulcer models. In this study, we investigated whether BuOH fraction activates keratinocyte and fibroblast via wound closure test and migration assay. In the scratch test, BuOH fraction accelerated the closure of a monolayer wound scratch at $100{\mu}g/mL$. After treatment with BuOH fraction for 18 h, keratinocytes showed a increase in migration at $25{\mu}g/mL$, whereas the migration of fibroblast increased significantly at $100{\mu}g/mL$ of BuOH fraction compared to control. The mechanism that the BuOH fraction of HS helps to promote healing by inflammation is possibly associated with the migration of keratinocyte and fibroblast.

We previously reported that Hydnocarpi Semen (HS) has a wound healing effect on diabetic foot ulcer lesion in mice. In this study, ethylacetate (EtOAc) fraction from HS extract were evaluated for their wound healing activity by using in vitro acute inflammation model. GC and GC/MS analysis shows that the main constituents in EtOAc fraction are chaulmoogric acid, hydnocarpic acid, and gorlic acid. EtOAc fraction activated macrophages to increase the production of TNF-${\alpha}$. The fraction also increased the production of TGF-${\beta}$ and VEGF, which induced fibroblast activation and angiogenesis. These results suggest that the mechanism that the fraction helps to enhance healing of skin wound is possibly associated with the production of TNF-${\alpha}$, as well as secretion of VEGF, TGF-${\beta}$ and HS may have a new bioactive material for the treatment of skin wound.

항산화 활성과 미백활성을 갖는 새로운 화장품 소재를 찾기 위하여 한방 소재로 사용되는 빈랑자[Areca semen (A. semen)]를 유기용매 추출을 통하여 활성분획을 분리하였다. 추출된 활성 분획을 이용하여 항산화 활성, 피부 상재균에 대한 항균 활성, 세포독성 및 세포 내 멜라닌 합성 저해능 및 멜라닌 합성에 관여하는 유전자의 저해 활성을 확인함으로써 미백 화장품 소재로서의 가능성을 확인하였다. 빈랑자는 에틸아세테이트 용매의 분획을 동결 건조하여 분말형태로 제조하였으며 이를 이후 실험에 사용하였다. 빈랑자 추출물에서 페놀성 물질은 $301.35{\pm}0.88{\mu}g/mg$으로 측정되었다. 항산화 효과는 DPPH assay와 FRAP assay를 이용하여 측정하였으며, 대조군으로 사용된 ascorbic acid와 비슷하게 측정되었다. 피부상재균에 대한 항균활성은 Staphylococcus aureus (S. aureus), Staphylococcus epidermidis (S. epidermidis)에서 모두 $80{\mu}g/mL$의 농도에서 항균활성을 갖는 것으로 나타났으며 Escherichia coli (E. coli)에서는 항균활성을 나타내지 않았다. 미백소재로서의 활성을 확인하여 B16/F1 mouse melanoma cell을 이용하였으며 최대 처리농도인 $80{\mu}g/mL$에서는 독성을 나타내지 않았다. 또한 세포 내 멜라닌 합성 저해능은 $80{\mu}g/mL$에서 $29.44{\pm}0.71%$로 측정되었다. 또한 멜라닌 합성에 관여하는 유전자의 발현량은 mRNA expression assay를 통하여 확인하였으며, 그 결과 tyrosinase와 MITF 유전자는 농도 의존적으로 감소하는 경향을 나타내었다. 따라서 이러한 결과를 통하여 빈랑자의 에틸아세테이트 분획은 항산화와 미백효과를 나타내는 것으로 확인되었으며 화장품 소재로서의 사용 가능성을 확인하였다.
