Objective : This experimental study was carried out to investigate the effects of Persicae Semen(PS) and Caesalpiniae Lignum(CL) on the intravascular coagulation which is considered as thrombosis. Methods : Rats were pretreated orally with PS and CL extracts(PS: 8.45mg/100g, CL: 4.4mg/100g), and 1 hour later, to induce thrombosis, were given an endotoxin(0.01mg/100g) injection into the caudal vein. After 4hours we collected blood by cardiac puncture and measured the platelet count, the prothrombin time, the level of fibrinogen and the FDP(fibrinogen degradation product). Results : PS and CL supressed the decrease of the Platelet count and the prolongation of prothrombin time. In these factors, both groups showed significant effect. Both groups supressed the decrease of the fibrinogen level and the increase of the FDP level. But, only the PS group showed a significant effect on the fibrinogen level, and only the Cle CL group showed a significant effect on FDP level. Conclusions : PS had significant effects on the platelet count, the prothrombin time, and the FDP level. CL had significant effects on the platelet count, the prothrombin time, and the fibrinogen level. Therefore, PerSicae Semen and Caesalpiniae Lignum seem to be applicable to treating the diseases related to thrombosis.

The purpose of this study was to investigate the anticancer effects of Caesalpiniae Lignum (Somok) on HepG2 cells, a human liver cancer cell line. To study the cytotoxic effect of Caesalpiniae Lignum methanol extract (CL-MeOH) on HepG2 cells, the cells were treated with various concentrations of CL-MeOH and then cell viability was determined by XTT reduction method and trypan blue exclusion assay. CL-MeOH reduced proliferation of HepG2 cells in a dose-dependent manner. To confirm the induction of apoptosis, HepG2 cells were treated with various concentrations of CL-MeOH. The activation of caspase 3 and the cleavage of poly ADP-ribose polymerase (PARP), a substrate for caspase-3 and a typical sign of apoptosis, was examined by western blot analysis. CL-MeOH decreased procaspase 3 level in a dose-dependent manner and induced the clevage of PARP at concentration> $200{\mu}/ml$. Mitogen-activated protein (MAP) kinase signaling cascades are multi-functional signaling networks that influence cell growth, differentiation, apoptosis, and cellular responses to stress. CL-MeOH-induced MAPK activation was examined by Western blot for phosphorylated ERK, p38 and JNK. CL-MeOH significantly increased p38 phosphorylation and JNK phosphorylation in a dose-dependent manner. Inhibition of p38 function using the selective inhibitor SB20358O results in inhibition of apoptosis by CL-MeOH. These results suggest that CL-MeOH-induced apoptosis is MAP kinase-dependent apoptoric pathway. These results suggest that CL-MeOH is potentially useful as a chemotherapeutic agent in human liver cancer.

Treatment of oral cancers with chemotherapeutic agents are evaluated as an effective method for remission to reduce cancer proliferation nowadays. But, minimization of side-effects such as bone marrow suppression, gastrointestinal toxicity and renal damage is another problem to be solved. Thus, a possible approach to develop a clinically applicable chemotherapeutic agents is to screen anticancer activity among traditional medicinal plants which have been used for thousands of years with very low side-effects in orient. In this study we focused on screening anti-oral cancer activities among 14 traditional medicinal plant extracts that revealed anticancer activities on other solid tumors. The results were as follow : 1. Methanol extract of Lepidium apetalum showed the highest anti-oral cancer activity against A253 cells. At concentration of $4{\mu}g/ml$, the cell viability was 48% under our experimental condition. $IC_{50}$ value obtained was $4{\mu}g/ml$. 2. Methanol extract of Coptis japonica and Solanum nigrum were effective on KB cells. Cell viability observed were 62% and 67% at concentration of $4{\mu}g/ml$, and $IC_{50}$ values were $12{\mu}g/ml$ and $10{\mu}g/ml$ respectively. 3. When the methanol extract of Lonicera caerule was combined with $2{\mu}g/ml$ of cisplatin, the anticancer activity was synergistically increased. One hundred ${\mu}g/ml$ of Lonicera caerule showed 92%(alone) or 59%(combined with cisplatin) cell viabilities. $IC_{50}$ value of Lonicera caerule extract against KB cells was reduced from $301{\mu}g/ml$ to $126{\mu}g/ml$ when combined with $2{\mu}g/ml$ of cisplatin. 4. Medicinal plant extracts effective on both A253 and KB cells were Coptis japonica, Lepidium apetalum, Solanum nigrum, Caesalpiniae Lignum, Curcuma aromatica.

Identification of natural compounds that can prevent the development of obesity in vivo is time consuming and expensive. We have used in vitro systems derived from pig adipose tissue to screen simple aqueous or ethanolic extracts of Korean medicinal herbs (KMH) for their anti-adipogenic potential. A total of 183 extracts were tested for their actions in lipogenesis of pig adipose tissue and differentiation of pig preadipocytes. Ethanol extracts were prepared from 72 and aqueous extracts were prepared from 111 medicinal herbs. Both an ethanolic and an aqueous extract were prepared from 65 of these. Thirteen extracts substantially altered rates of lipogenesis in vitro. The effects of KMH on lipogenesis of pig adipose tissue are as follows. Elevens reduced lipogenesis to rates that were more than 40% lower than control and four of these reduced rates of lipogenesis by more than 70%. The most potent anti-lipogenic extracts were those obtained in ethanol from Iridaceae and from Sophora flavescens AIT as well as both the aqueous and ethanolic extracts from Lysimachia vulgaris L. Two extracts, those prepared in water from Caesalpiniae lignum and from Phellodendri cortex, were found to promote rates of lipogenesis in vitro. The effects of KMH on differentiation of pig preadoipocytes are as follows. Twentyeight extracts altered the rates of differentiation of cultured porcine preadipocytes. Sixteen increased and twelve reduced the rates of differentiation of preadipocytes. Extracts prepared in ethanol from Moutan radicis cortex and from Ostericum koreanum and those prepared in water from Angelicae gigantis radix, from Inula henenium L and from Magnolia flos doubled the rate of differentiation of cultured porcine preadipocytes. Ten extracts reduced the in vitro rate of differentiation of porcine preadipocytes by more than 35%. These were the ethanolic extracts from Glycyrrizae radix, Nepetae spica and from Polygala myrtifolia and the aqueous extracts from Amaranthaceae, Asparagus cochinchinesis, Atractylodis rhizoma alba, Citrus junos TANAKA, Cyperus rotundus, Epimedium grandiflorum and from Moutan radicis cortex. Only the ethanolic extract from Polygala myrtifolia was able to both reduce lipogenesis in adipose tissue slices and retard differentiation of cultured preadipocytes. The results of our study will provide meaningful information to identify medicinal herbs which would reduce fat deposition in livestocks and humans.
