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: This study was conducted to investigate the effects of Ginseng Radix Alba extract solution on the cell cycle regulation, apoptosis of human uterine myoma cells. Methods: Primary cultured human uterine myoma cells were treated with extract solution of Ginseng Radix Alba concentration of 1, 10 and $100mg/m{\ell}$ for 48 hours. We underwent flow cytometry and western blotting for cell cycle and apoptosis related factors. Results: In flow cytometry, a slight promotion of G1 phase in $1mg/m{\ell}$ group had been observed but, simultaneously a delay of G1 phase in 10 and $100mg/m{\ell}$ groups were also observed. The manifestation of cyclin D1 in Ginseng Radix Alba extract solution medicated group increased compared to the control group. The manifestation of Bax controlling apoptosis increased in terms of concentration but Bcl-2 showed no change. Also VEGF increased in terms of concentration. Conclusion: The present study suggests that Ginseng Radix Alba extract solution treatment in human uterine myoma cells induce the delay of cell cycle and apoptosis. These results suggest that Ginseng Radix Alba will be a promising agent for use in therapeutics agents against human uterine myoma.

This work examines the effect of treatment with Gyukhachukeotang on the growth of uterine myomal cells. Comparisons of cell growth, MAP kinase activity and expression of bcl-2 (apoptosis-related gene) were made between the control and experimental samples. The results as fallows; 1. Any concentration of Gyukhachukeotang above 0.01% yielded growth inhibition. Concentrations of 5% and 10% stopped all cell growth, demonstrating the effectiveness of Gyukhachukeotang as a growth inhibitor on uterine myomal cells. 2. The MAP kinase activity in uterine myomal cells treated with Gyukhachukeotang was decreased to a high degree at the concentration of 10%, and some inhibition of activity was detected at a concentration of 5%. 3. The expression of bcl-2, a Cell Apoptosis-related gene, in uterine myoma cells treated with Gyukhachukeotang was gradually increased with increasing concentration of Gyukhachukeotang. These results indicate the ability of Gyukhachukeotang to control uterine myomal cell growth, with concurrent reduction of MAP kinase activity. Treatment with Gyukhachukeotang appears to trigger a normal apoptosis response, as indicated by increased bcl-2 expression. This observed increase in apoptosis indicates that Gyukhachukeotang is an appropriate prescription to treat uterine myomal cells.

As an initial step toward better understanding of the molecular mechanism of estrogen-dependent growth in myoma, an optimal primary cell culture condition has been developed and examined by this study. Myoma and myometrium were cultured by two different methods. Culture stability and $E_2$-responsiveness in stable culture were studied. The culture of digested tissue pieces(Method 2) was found to be a stable culture method for the myoma and myometrium showing a favorable response to estrogen. mRNA expression of PR, IGF-1 and IGF-1 receptor genes was enhanced by $E_2$. The gene responses to $E_2$ were higher in myoma compared with myometrium. Moreover, these responses were more expressive in tissues than in the surrounding cells in primary culture of normal myometrium and myoma, implying a vital role of cell communication through the extracellular matrix in maintaining the estrogen-responsiveness. The development of an improved cell culture system for myoma provides an in vitro tool to further investigate the basis of the tumor formation.

The factors involved in the initial neoplastic transformation and subsquent growth of uterine fibroid are poorly understood. The reduction in uterine fibroid volume associated with the chronic administration of the mechanisms mediating the decrease in fibroid volume in GnRH-a treated patients are poorly defined. The purpose of this study was to determine the proliferating cell nuclear antigen(PCNA) in fibroid from-women pretreated with GnRH analogue(GnRH-a) compared with controls. Tissue was obtained from 16 premenopausal women with uterine fibroid who received GnRH-a(D-Trp6-GnRH) intramusculary every 28 days for four injections. The mean proliferating index(PI) in patients with uterine fibroids was $2.25{\pm}0.9$, and in controls was $8.82{\pm}1.8$(P<0.001). The proliferating index was not corrleated with the reduction of fibroid volume. In this clinical study, although hypoestrogenism may be the main factor that reduce the volume of fibroid, other factors are also considered to be involved in that process. And the regrowth of uterine fibroid may be affected by increased production of PCNA after stopping GnRH-a.

Objective : The purpose of this report was to provide the information about activity and safety of Ojeok-san by analyzing domestic/international papers about Ojeok-san. Methods : Domestic/international papers related to Ojeok-san were reviewed and analyzed. These papers were then classified by year, experimental method and subject. Results : The following results were obtained in this study. 1. The studies of Ojeok-san started from 1984 and has continuously increased. The studies were mainly focused on experimental models rather than clinical studies. 2. By subject, papers related to safety were most common with 5 papers among 20 papers. Besides there were papers related to efficacy of analgesic, anti-hyperlipidemic, anti-blood stasis and treatment for uterine myoma. 3. The papers related to safety were mainly focused on the effect of Okeok-san on liver function, renal function or metal concentration of organs such as blood, brain, liver, kidney and bone. Ojeok-san proved to be safe, but more clinical studies regarding the safety are needed hereafter. 4. Papers related to analgesic, anti-pyretic, anti-phlogistic activities of Ojeok-san were in vivo studies, and other papers were about anti-hyperlipidemic activity, apoptosis inducing activity on uterine myeloma cell line and anti blood static activity on hydrocortisone acetate induced blood statis model. 5. Case reports were about anti-lipidemia, analgesic effect for mastalgia/back pain and anxiety disorder due to climacteric changes. Conclusion : Ojeok-san is being used in various ways with analgesic, anti-pyretic, anti-phlogistic, anti-hyperlipidemic, anti-tumor or anti-blood statis activity. However, mechanism study should be conducted at the molecular biology level and more clinical studies on the efficacy of Ojeok-san are needed.
