Purpose: This study was conducted to investigate the effects of Hominis Placenta (紫河車) on the growth of human uterine myoma cells and cell apoptosis. Methods: Human uterine leiomyoma cells were cultured and treated with Hominis Placenta extract for 48 hours. Cell proliferation and activity was analyzed by MTT assay. We analyzed the cell cycle of human uterine myoma cells treated Hominis Placenta extract by FACS. Expression of proteins related to cell apoptosis (Bax, Bcl-2), cyclin-D1 and VEGF were evaluated by Western blotting method. Results: The human uterine myoma cells treated by Hominis Placenta extract didn't proliferate below the concentration of $10mg/m{\ell}$. And there was no remarkable difference on cell cycle analysis below the concentration of $10mg/m{\ell}$. The expression of Bax was decreased and the expression of Bcl-2 was increased after the treatment of Hominis Placenta extract. But the expressions of cyclin-D1 and VEGF were increased after the treatment of Hominis Placenta extract. Conclusion: This study suggests that Hominis Placenta induce uterine myoma cell apoptosis and have effect on the myoma cell proliferation in the concentraion below $10mg/m{\ell}$.

Purpose. Free radicals are implicated in the pathophysiology of aging, ischemic injury and neurodegenerative disorders. To deform]no whether Hominis Placenta extract prevents $H_2O_2$-induced apoptosis, we have performed morphological and biochemical analyses for the detection of apoptotic phenomena in the pineal tumor cell line $PGT-{\beta}$ We have also peformed cytochemical and immunocytochemical analyses for the detection of changes in nitric oxide synthase (NOS) activity and estimated the expression . of apoptotic genes using reverse transcription-polymerase chain reaction (RT-PCR) Methods. $PGT-{\beta}\;cells$ were pretreated with Hominis Placenta extracts $(0,\;10^{-2}\;{\mu}g/ml)$ for 2 hours and then exposed to $H_2O_2\;(0,\;50\;{\mu}M)$ for 3 hours. Appearance of apoptotic characteristics were monitored using 4, 6-diamidino-2-phenylindole dihydrochloride (DAPI) staining assay, terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL) assay and flow cytometric analysis. NOS activity was measured by NADPH-diaphorase cytochemistry. Expression of inducible NOS (iNOS) and nuclear factor kappa B (NF k B) was assessed via immunocytochemistry. The expression of apoptotic genes was examined by RT-PCR. Results. After 3 flours of exposure to $H_2O_2$, it was shown that $PGT-{\beta}\;cells$ treated with $H_2O_2(50\;{\mu}M)$ exhibit classical apoptotic features and increases in NOS activity and caspase-3 expression. Treatment with Hominis Placenta extract resulted in a reduced occurrence of apoptotic features. DAPI staining, TUNEL and flow cytometric assays revealed decreases in the occurrence of nuclear fragmentation and in the sub-Gl fraction in the $PGT-{\beta}\;cells$ treated with Hominis Placenta extract. Cells treated with Hominis Placenta extract also showed lower activity of NADPH-diaphorase and immunoreactivities of both iNOS and NF k B than those of $H_2O_2$-treated cells which were not treated with Hominis Placenta extract. By RT-PCR, it was shown that the level of caspase-3 mRNA was derreased In the cells treated with Hominis Placenta . extract. Conclusions. This study shows that Hominis Placenta extract prevents $H_2O_2$-induced apoptosis in $PGT-{\beta}\;cells$; inhibitions of iNOS and caspnse-3 are possible mechanisms of the protection against apoptosis.

Hominis placenta pharmacopuncture, a treatment that injects Hominis placenta extract into acupoints, has been suggested in the literature and researches that it could be used for cognitive decline. We experienced a case of mild neurocognitive disorder treated with Hominis placenta pharmacopuncture. Hominis placenta pharmacopuncture could be a possible treatment modality producing substantial clinical result in cognitive function which is assessed with Mini-Mental State Examination-Dementia Screening (MMSE-DS), Korean Version of Montreal Cognitive Assessment (MoCA-K), and Korean-Dementia Rating Scale (K-DRS). A 84-year-old man with mild neurocognitive disorder received Hominis placenta pharmacopuncture on GV20, CV12, and bilateral ST36 for a month. The results of neuropsychological examination showed increase in scores after treatment of Hominis placenta pharmacopuncture. Before treatment, they were 15 points for MoCA-K, and 120 points for K-DRS (7.6%), but after treatment, they elevated by 21 points for MoCA-K and 137 points for K-DRS (100%). MMSE-DS score was 28 points, unchanged before and after treatment. It did not cause any side-effect. Hominis placenta pharmacopuncture could be a safe option for treating mild neurocognitive disorder.

Hominis placenta (HP) has been used as an agent for promoting physiological function in traditional asian medicine. The present study was peformed to investigate whether HP acupuncture treatment in an experimental tumor mice model inhibit tumor growth through immunomodulatory effects. Mice were inoculated subcutaneously with colon26-L5 cells on the back. Three days after tumor inoculation, HP herbal acupuncture treatment was conducted on BL18 acupoint every other day for three weeks. HP Herbal acupuncture treatment significantly suppressed the primary tumor growth and prolonged survival rate. To evaluate immunomodulatory effect of HP acupuncture, splenocytes proliferation assay, fluorescence-activated cell sorting (FACS) and ELISA for IFN- ${\gamma}$, and IL-4 cytokine level. HP herbal acupuncture enhanced the mitogenic activity of Balb/c whole splenocytes induced by various mitogenic stimuli and increased immune cell population such as T cell, B cell, Th cell, Tc cell and Macrophages. HP herbal acupuncture caused a marked increase of production of Th1 cytokine (IFN- ${\gamma}$ ,) and decrease of production of Th2 cytokine (IL-4). These results indicated that HP herbal acupuncture suppresses tumor growth through a mechanism leading to a Th1 dominant immune state.

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.
