  • 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.

  • The effect of protein extract from Asterina pectinifera on breast cancer chemopreventive (aromatase and cyclooxygenase-2) and metastatic (matrix metalloproteinase) enzymes was tested. Protein extract from A. pectinifera was capable of suppressing aromatase in a human placenta microsomal assay. Cyclooxygenase-2 (COX-2) activity was significantly inhibited by the protein extract from A. pectinifera at concentrations of 10, 20 and $40{\mu}g/m{\ell}$. The extract markedly reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated matrix metalloproteinase (MMP)-9 activity. These results suggest that A. pectinifera could be of therapeutic value in preventing human breast cancer.

  • 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.

  • This study was performed to elucidate anticancer activities of various parts, such as peel, flesh, placenta, seed, stalk and stem leaf of oriental melon. Chemopreventive and anticancer effects of oriental melon extract were evaluated by detoxifying enzyme, quinone reductase (QR) inductive activity, cytotoxicity and growth inhibitory effect against hepatoma cell. Stalk and stem leaf extracts of oriental melon showed the increment of QR inductive activity with dose-dependent manner and induced quinone reductase 3.9, 1.5-fold at $200{\mu}g/mL$ respectively compared to control. The growth inhibitory effect of oriental melon extract against mouse hepatoma cell (Hepa1c1c7) was investigated by crystal violet (CV) assay. Stalk and stem leaf of oriental melon showed potent growth inhibitory effect. Based on these result, the growth inhibitory effects of stalk, stem leaf at various concentration were examined in detail by MTT assay using human hepatoma cancer cell (HepG2). All of two parts showed growth inhibitory effects and expecially stalk exhibited inhibitory effect of 60.3% at maximum concentration. The above results suggest that stalk of oriental melon has a possibility as a source of natural cancer chemopreventive materials.

  • 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.
