  • Human placental extract (HPE), which is prepared from the placenta of healthy pregnant females, has been widely used in clinical field. HPE is known to possess anti-inflammatory, anti-viral, anti-oxidative, anti-mutagenic, and analgesic properties. In this study, the effect of HPE against lipopolysaccharide (LPS)-induced inflammation was investigated. From the present results, HPE was shown to suppress prostaglandin E2 synthesis (PGE2) and nitric oxide (NO) production by inhibition on the LPS-stimulated enhancement of the cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions in mouse BV2 microglial cells. These results suggest that HPE may offer a valuable mean of therapy for the treatment of brain inflammatory diseases by attenuating LPS-induced PGE2 and NO production.

  • Vitiligo does not have a baneful influence on life and function of the body directly, but is a serious disease in that most patients suffer from difficulties in social life and considerable stress. We cured a vitiligo patient with a few depigmented patches in front of the left ear using aqua-acupuncture with hominis placenta and psoraleae fructus extract. Since this is just one case report, more case studies and research will be necessary.

  • Objectives: This study was conducted to compare the effects of Hominis placenta (Jahage, J) and wild ginseng (SanSam, S) pharmacopuncture drugs on muscle differentiation and energy metabolism regulation in C2C12 myotubes. Methods: The C2C12 myoblasts were differentiated into myotubes for 5 days by replacing in medium containing 2% horse serum and then treated with J and S pharmacopuncture extract at different concentrations for 24 hr. The expression of myosin heavy chain and energy metabolism-regulating factors, myosin heavy chain (MHC), nuclear respiratory factor-1 (NRF-1), and proliferator-activated receptor γ coactivator-1 alpha (PGC-1α) were determined in C2C12 myotubes by western blot. Additionally, the phosphorylation of AMPK and the expression of mitochondrial biogenesis, including sirtuin 1 (SIRT1) were determined in the myotubes. Results: As a result, treatment with J and S pharmacopuncture extract at 0.1 and 1 mg/mL increased the MHC expression in C2C12 myotubes compared with non-treated cells, but only S pharmacopuncture was shown a significant and distinct increase in the expression. Expression of TFAM and NRF-1 was also shown significant increases in S and J pharmacopuncture in C2C12 myotubes compared to non-treated cells. The phosphorylation of AMPK and the expression of PGC-1α and SIRT1 showed increased expression in S and J pharmacopuncture compared to non-treated cells. The effect of low-dose of J pharmacopuncture on the phosphorylated adenosine monophosphate-activated protein kinase (AMPK) and PGC-1α expression was greater than that of S pharmacopuncture. Conclusions: In conclusion, both J and S pharmacopuncture promote muscle differentiation in C2C12 myoblasts into myotubes and energy metabolism through the AMPK/SIRT1 signaling pathway. This indicates that the pharmacopuncture with tonic herbal medicines can help to improve skeletal muscle function.

  • 별불가사리 단백추출물을 조제하여 유방암 발생 및 전이억제효과를 측정한 결과 종양세포증식에 관여하는 aromatase 활성이 농도의존적으로 억제효과가 있었으며, 침윤성 유방암에서 과발현하는 COX-2 단백질 발현을 억제하였다. 그리고 유방암이 진행될수록 활성이 증가하는 MMP-9도 농도의존적 저해율을 보였다. 그러므로 별불가사리 단백추출물은 유방암억제기전에 관련된 더 많은 연구를 통하여 유방암 예방물질로서 개발 가능성이 있는 것으로 보인다.

  • Objectives: This study was performed to investigate the effects of Hominis Placenta pharmacopuncture (HPP) therapy on the experimentally-induced endometriosis in the rats. Materials and Methods: Endometriosis was induced in rats by autotransplanting uterine tissue to the peritoneum and divided them into three groups: (1) sham-operated group (n=8), (2) surgically induced endometriosis and untreated control group (n=8), (3) surgically induced endometriosis and HPP treated group. Sham-operated group and control group were inject with normal saline once a every other day for 30days, while treated group was injected with HPP extract once a every other day for same duration. Injected point of HPP and normal saline were subcutaneous tissue at Gwanwon (CV4) acupoint. Then we measured the body weight, the volume of endometriotic implants, the weigh of uterus and ovaries, and investigated the concentration of cytokines (MCP-1, TNF-${\alpha}$) in peritoneal fluids. Histopathology, immunohistochemisty for COX-2 and VEGF, and histochemistry for mast cell in transplanted uterine tissue were performed. Results: The volume ($mm^2$) of endometriotic implants in HPP treated group ($55.4{\pm}41.6$) was significantly decreased (p<0.01) compared with control group ($140{\pm}66.1$). And the concentration (pg/ml) of MCP-1 in peritoneal fluids in HPP treated group ($1117.6{\pm}60.5$) was significantly decreased (p<0.01) compared with control group ($1446.2{\pm}280.3$). The concentration (pg/ml) of TNF-${\alpha}$ in peritoneal fluids in HPP treated group ($80.6{\pm}31.4$) was decreased (p<0.01) compared with control group ($145.3{\pm}86.9$). Histopathologically, proliferation of endometriotic epithelia, infiltration of inflammatory cell and angiogenesis in transplanted uterine tissue of HPP treated group were weakly observed than those of control group. The COX-2 expression in endometrial, epithelial and stromal cells in transplanted uterine tissue of HPP treated group was decreased compared with control group. The VEGF expression of endometriotic epithelia, neovascular endothelia and stromal cell in transplanted uterine tissue of HPP treated group were weakly observed than those of control goup. Conclusions: HPP is effect on Endometriosis of rats by Experimentally-induced.

  • 본 연구에서는 참외 추출물의 항암활성에 대해 알아보기 위해 참외를 부위별로 나누어 quinone reductase 유도활성과 다양한 간암세포에서의 증식 억제활성을 조사하였다. 참외 꼭지와 참외 줄기 잎 부위에서 농도의존적으로 QR 유도활성이 증가하였고, $200{\mu}g/mL$ 농도에서는 각각 3.9, 1.5배의 유도활성을 나타내었다. 암세포 사멸 활성 측정법을 통한 항암활성 평가 실험에서 마우스 유래의 간암세포인 Hepa1c1c7 세포에 대해서 조사한 결과 꼭지와 줄기 잎 부위에서 높은 암세포 독성을 보였다. 이러한 결과를 기초로 인체유래의 암세포에 대한 항암활성을 평가하기 위해 인체유래 간암 세포주인 HepG2에 대한 세포 증식 억제활성을 농도별로 조사하였다. 꼭지와 줄기 잎 부위 모두 인체유래 간암 세포에 대해 증식 억제효과를 보여주었지만, 특히 꼭지 부위는 최고농도에서 60.3%의 높은 증식 억제효과를 보였다. 그러나 마우스 유래의 간암세포에 대한 활성보다 인체유래 간암세포에 대한 활성이 낮게 나타났다. 참외의 꼭지 추출물에서 QR 유도활성과 항암활성을 확인함으로써 향후 참외 비가식 부위의 기능성 소재로의 이용화에 대한 연구가 필요할 것으로 생각된다.

  • The anti-thrombic properties of the oriental herbal medicine Daejowhan(DJW, 大造丸) which consists of 11 kinds of herbs (indicated as ratio) of Rehmanniae Radix 24%, Hominis Placenta 5%, Testudinis Carapax 9%, Eucommiae Cortex 9%, Asparagi Radix 9%, Phellodendri Cortex 9%, Achyranthis Radix 7%, Liriopis Tuber 7%, Angelicae Sinensis Radix 7%, Ginseng Radix 5% and Schizandrae Fructus 3% were investigated. The water extracts from DJW inhibited Platelet-activating factor(PAF) induced platelet aggregation. DJW was extracted with methanol and further fractionated by ethylacetate. A 70% methanol extract showed a strong inhibition against PAF-induced aggregation in vitro and in vivo assays. The ethylacetate soluble fraction was shown to have inhibitory effect on PAF-induced platelet aggregation in vitro assay. The ethylacetate soluble fraction specially protected against the lethality of PAF, while verapamil did not afford any protection. These results indicate that the water extracts and alcoholic-fractions inhibit the action of PAF in vivo by an antagonistic effect on PAF, so that it may be useful in treating disorders caused by PAF, such as acute allergy, inflammation, asthma, gastrointestinal ulceration, toxic shock and so forth. DJW was investigated regarding its assumed anti-thrombic action on human platelets which was deduced from its ability to suppress Arachidonic acid(AA)-induced aggregation, exocytosis of ATP, and inhibition of Cyclooxygenase(COX) and Thromboxane synthase(TXS) activity. The latter two effects were estimated from the generation of Prostaglandin $E_2(PGE_2)$ and Thromboxane $A_2(TXA_2)$ respectively. Exogenously applied AA ($100{\mu}mol/{\ell}$) provoked a $89\%$ aggregation of platelets, the release of 14 pmol ATP, and the formation of either 225 pg $TXA_2$ or 45 pg $PGE_2$, each parameter being related to 106 platelets. An application of DJW 5 min before AA dose-dependently diminished aggregation, ATP-release and the synthesis of $TXA_2$ and $PGE_2$ with $IC_{50}$ values of 74, 108, 65, $72{\mu}g/m{\ell}$, respectively. The similarity of the $IC_{50}$ values suggest an inhibition of COX by DJW as primary target, thus suppressing the generation of $TXA_2$ which induces aggregation of platelets and exocytosis of ATP by its binding on $TXA_2$-receptors.
