Objectives : We investigated the effects of Hominis placenta Herbal acupuncture on rheumatoid arthritis. Methods : We investigated the Type II collagen-induced arthritis test, vascular permeability test, phenyl benzoquinone-induced writhing test, hot plate test, carbon clearance test, determination of prostaglandin $E_2$ content and cyclooxygenase-2 activity test. Results : Hominis placenta Herbal acupuncture suppressed Type II collagen-induced arthritis in DBA/1J mice and vascular permeability with 10.2% inhibition in ICR mice. We see the phenyl benzoquinone-induced writhing test and the hot plate test in the analgesic activity test. In the phenyl benzoquinone-induced writhing test, Hominis placenta Herbal acupuncture showed that it increased its analgesic effect more than the control(test?) by 85.5%. In the hot plate test, it was also shown that the analgesic effect increased more than the control(test) by 32.1%. In the carbon clearance test, the immuno-stimulatory effect showed more than the control(test) by 8.0%. The formation of prostaglandin $E_2$ was also reduced more than the control(test) by 10.1%. Finally, cyclooxygenase-2 activity was inhibitedwith 36.3%. Conclusions : Hominis placenta Herbal acupuncture may be useful for the treatment of rheumatoid arthritis after injection.

Objectives : DNA methylation is one of the best characterized epigenetic mechanisms that play a regulatory role in genome programming and imprinting during embryogenesis. In this present study, we investigated the association between DNA methylation in the human placenta and the maternal folate and homocysteine concentrations on the Methylenetetrahydrofolatereductase (MTHFR) genetic polymorphism during pregnancy. Methods : We investigated 107 pregnant women who visited Ewha Woman's University Hospital for prenatal care during their $24{\sim}28$ weeks-period of gestation. During the second trimester, we measured the serum homocysteine and folate concentrations . The MTHFR 677 genetic polymorphism was determine by performing PCR-RFLP assay. The expression of DNA methylation in the human placentas was estimated by using immunohistochemistry method. Results : Serum folate was negatively correlated with the serum homocysteine concentration for all the MTHFR genotypes. We found positive correlation between the folate concentrations and the DNA methylation in the human placenta (p<0.05). An increasing concentration of homocysteine was associated with reduced DNA methylation in the human placenta. The coefficient value was -2.03 (-3.77, -0.29) on the regression model (p<0.05). Conclusion : These findings suggest that the maternal folate and homocysteine levels along with the MTHFR 677 genetic polymorphism during pregnancy affect the DNA methylation in the human placenta.

Objectives : Washing face is the first step in skin beauty and health. I wanted to study the cleansing effect by using Placenta cp (cold process) soap. The skin condition is greatly influenced by the external environment such as lifestyle, drinking, smoking, and stress etc. I tried to measure the skin change state without environmental factors. Methods : In order to examine the effect before and after washing face under the same conditions, the same water and towel were used in the same place. The skin test was performed before and 10 minutes after washing. As a control group, a case of washing with water and foam cleanser. I compared and analyzed three cases: water washing, F/C (foam cleanser) washing, and Placenta cp soap washing. Results : In the case of water washing, it was significantly reduced in pores and increased in facial temperature. In the case of F/C washing, the facial temperature was significantly increased, but the decrease in moisture. In the case of washing with Placenta cp soap, significant reductions in T-zone and U-zone oil content, reduction in pore size, and increase in facial skin temperature were observed. Conclusion : In the case of Placenta cp soap, it is thought to be suitable for oily skin type, because of significant decrease in T-zone and U-zone oil content. It is thought to have the effect of increasing blood circulation in the facial skin and to reduce pores for oily skin types.

Background: Hystricomorpha rodents display a similar placentation model to humans. The present study was carried out considering the scarcity of information concerning the placental development in agouti. Objective: Describe the microscopy of the placenta, subplacenta and yolk sac of agoutis in early pregnancy and report on the inversion of the yolk sac. Methods: Fifteen females between the 14^th-32^nd day of gestation were used following euthanasia. Gestational buttons were collected, fixed, processed, stained to optical microscopy or immunohistochemistry. Results: Chorioallantoic placenta (CP) ranged from conical to a half-sphere, as follows: from the 14^th to 17^th day, the CP displays an inverted "V" shape, predominantly formed by cytotrophoblasts; from 20 to 22 days, formed almost entirely by cytotrophoblasts; at 28 days, a half sphere, with distinct lobes and interlobular area, numerous maternal gaps delimited by syncytiotrophoblasts and trophoblast giant cells; at 32 days, globose and undergoing the maturation process. Subplacenta, located between decidua and CP, initially presents septa consisting of simple columnar epithelium and after 17 days, comprising stratified epithelium. Visceral yolk sac (VYS) is attached to two CP projections between 14 and 17 days, formed by a simple cubic epithelium and inverted. Between 20 and 22 days, the epithelium displays apical villous projections with cytoplasmic vacuoles and a vascularized mesoderm. After the 24^th day, the VYS near the placenta is pleated, very vascularized and villous, with decreased villi sizes further away from the placenta. Conclusion: The agouti CP displays similar characteristics to other hystricomorpha, including placenta lobulation, a subplacenta and an inverted vitelline placenta.

Placenta has been shown to be a site of expression of several of the monoamine membrane uptake transporters. However, the correlation between the expressions of norepinephrine transporter (NET) and placental development including gynecological diseases is still unknown. To investigate the expression and functions of NET in placenta, we conducted to compare NET expression in normal and preeclamptic placenta and analyzed the function of NET in HTR8-SV/neo trophoblast cells after NET gene transfection. The expression of NET was analyzed in placental tissues from the following groups of patients (none underwent labor): 1) term normal placenta (n=15); 2) term with preeclamptic placeneta (n=15); and 3) pre-term with preeclamptic placenta (n=11) using semi-quantitative RT-PCR, immunohistochemistry, and Western blot. In order to evaluate the function of NET, NET gene plasmid and NET gene-specific siRNA were trnasfected into HTR-8/SVneo trophoblast cells for 24 hours. NET had low expression in the pre-eclamptic placenta compare with normal placenta but no difference in western blot data. NET was expressed in the trophoblasts, and the up-regulation of NET gene stimulated the invasion of HTR-8/SVneo trophoblast cells by 2.5 fold (p<0.05), whereas the NET-siRNA treatment reduced invasion rates. Also, we observed that the expression of NET induces to expression and activity of MMP-9 in HTR-8/SVneo trophoblast cells in zymography. The results suggest that the expression of NET were reduced in pre-eclampsia and should be inhibited invasion activity of trophoblasts. Therefore, these findings provide useful guidelines for the mechanisms of trophoblast invasion as well as for the basic understanding of gynecological diseases including pre-eclampsia.

Objectives : This study is to evaluate Effect of Inhibition Macrophage Migration Inhibitory Factor(MIF) activation by Hominis Placenta Herbal Acupuncture(HPA) on Rheumatic Arthritis(RA). Hominis Placenta is the placenta of healthy human, which is vital-strengthening medical stuff. In recent years, Hominis Placenta applied to chronic diseases because it makes us more resistance to diseases. Therefore it is supposed that HPA is effective on RA, a kind of autoimmune disease. When RA is induced, MIF is activated, too. MIF affects the process of inflammatory disease including RA. Methods : In order to investigate the effect of Hominis Placenta extraction on MIF(early RA inducing cytokine) and MMP(Matrix Metallo Proteinase)-9 mRNA expression by means of Reverse Transcriptase- Polymerase Chain Reaction(RT-PCR). In this study, we investigated the effect of Hominis Placenta extraction on MIF(early RA inducing cytokine) and MMP-9 mRNA expression by means of RT-PCR. Besides we investigated changing of MIF in synovial membrane and, Interleukin-6 receptor(IL-6R)-$\alpha$(pro-inflammatory cytokine), Signal transducers and activators of transcription(STAT)-3, MMP-9 after treating mouse, which is artificially attacked with RA, with HPA on its $ST_{35}$, LE201 in vivo. Results : 1. As a result of treating Lipopolysaccharide(LPS)-stimulated Raw246.7cell with HPA, MIF(RA related cytokine) and MMP-9 mRNA expression is reduced in vitro. And this reaction is concentration-dependatant. 2. In synovial membrane of the mice treated with HPA, inhibition of MIF, IL-6R-$\alpha$, STAT3 & MMP-9 activation is observed in vivo. Conclusions : From the above results, it might be suggested that HPA mitigate tissue damage originated from RA, because it intercepts the early process of by inhibition MIF activity.

Human placenta contains various kinds of nutritional elements essential for embryonic development. Currently, human placenta extracts are widely overused in Korea to improve certain health conditions (postmenopausal syndrome, liver function, and cosmetic purposes) without scientific evidence that they actually work. The use of placenta extracts should be restricted, due to a lack of systematic research on the therapeutic effectiveness and adverse results from these treatments. While the common adverse effects that have been reported are fever, rash, itching, nausea, vomiting, breast pain, and rare cases of anaphylactic shock, there have been no reports of pulmonary complications such as hypersensitivity pneumonitis. Recently, we experienced a patient with hypersensitivity pneumonitis following a placenta extract injection. To our knowledge, this is the first case of hypersensitivity pneumonitis associated with placenta extract use.

Seasonal changes and circadian rhythm of plasma prolactin(PRL) concentration in mammals are mediated by melatonin. Pinealectomy or denervation of the pineal gland produces an increase in plasma PRL level. In the rat placenta several members of the PRL family gene are expressed during the late pregnancy. However, the full spectrum of their expression mechanisms and regulatory factors are not elucidated yet. Present study aimed to investigate the local expression of the melatonin receptor la(Me $l_{la}$ ) gene and the effect of melatonin on expression of prolactin-like protein A(PLP-A), a member of the PRL-family gene in the rat placenta. According to the RT-PCR, northern blot and in situ hybridization experiments, Me $l_{la}$ gene was locally expressed in the rat placenta, Me $l_{la}$ mRNA was localized mainly in the placental junctional and labyrinth zones. Interestingly, junctional zone of the placenta showed strong expression of Me $l_{la}$ at daytime(16:00) than at nighttime(22:00). Melatonin agonist, chlorornelatonin decreased the PLP-A mRNA levels in the rat placenta. These results suggest that melatonin coupled with Me $l_{la}$ , may act as a regulation factor that mediates the expression of the PLP-A gene in the rat placenta.
