Prunus mume, also known as maesil, is a popular fruit consumed in East Asia (Korea, Japan, and China). It contains high amounts of organic acids, minerals, and polyphenols and has been used as a medication for fever, vomiting, and detoxification. In this study, the anti-proliferative and apoptotic effects of solvent fractions from maesil were evaluated using sulforhodamine B (SRB) assays, morphological evaluations, Hoechst 33258 staining, and western blotting. Addition of the maesil methanol fraction (MMF) and the maesil butanol fraction (MBF) significantly and dose-dependently decreased the cell viability of HT-29 human colon cancer cells. Colony-forming assays confirmed that the MMF and MBF treatments decreased colony numbers when compared with untreated control cells. Treatment of HT-29 cells with MMF and MBF caused a distortion of the cell morphology to a shrunken cell mass. Treatment with MMF and MBF also dose-dependently increased nuclear condensation and the formation of apoptotic bodies in HT-29 cells. Treatment with MMF and MBF significantly and dosedependently increased the expression of Bax (a pro-apoptotic protein), caspase-3, and poly ADP-ribose polymerase (PARP) and decreased the expression of Bcl-2 (an anti-apoptotic protein). MMF significantly and dose-dependently inhibited cell proliferation induced by bisphenol A, an environmental hormone. Therefore, MMF may have potential use as a functional food and as a possible therapeutic agent for the prevention of colon cancer.

In order to investigate whether or not CCD-986sk cell line can be affected by Korean Ecklonia stolonifera Okamura, we examined the MTT assay when we treated Korean Ecklonia stolonifera Okamura extract in CCD-986sk human fibroblast cell line. The sample were tested for cell proliferation activity by means of a modification of the MTT assay. Ecklonia stolonifera Okamura extract showed significantly strong cell proliferation activity at the range of from 6.25 mg $mL^{-1}$ to 1.56 mg $mL^{-1}$ compared with control group. And in order to search for inhibition agents of skin melanin formation, we tested for inhibition effect of melanin pigmentation of Korean Ecklonia stolonifera Okamura using Clone M-3 mouse melanocyte cell lines. when we treated the extracts of Ecklonia stolonifera Okamura to the mouse melanocyte cell lines, the sample showed a significantly little formation of melanin pigments compared with control group at the only range of 200 mg $mL^{-1}$. These results suggest that extract of Korean Ecklonia stolonifera Okamura may represents an excellent candidate for inhibition of melanin pigmentation and for protection of human skin aging at in vitro level.

This study was designed to investigate the effect of Plebeiae Herba (Salvia plebeia R. Br.) on the proliferation of AGS cell lines and the activation of splenocytes. In an anti-cancer test using AGS cells, water and ethanol extracts of Plebeiae Herba inhibited the growth of AGS cell lines and morphological changes were also observed in a dose-dependent manner. Water extract of Plebeiae Herba showed growth-inhibitory effect of 43.3% at $1,000{\mu}g/mL$ and 69.7% at $3,000{\mu}g/mL$. Ethanol extracts of Plebeiae Herba showed growth-inhibitory effect of approximately 37.3% for $1,000{\mu}g/mL$ and 75.8% for $3,000{\mu}g/mL$. The Plebeiae Herba induced the proliferation of spleen cells and increased interleukin (IL)-2, interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$. In conclusion, these results suggest that the Plebeiae Herba seems to have antiproliferationg effect against the AGS cell and acts as a potent immunomodulator.

Panax ginseng C.A. Meyer (P. ginseng) is known to exert a wide range of pharmacological effects both in vitro and in vivo. Although studies on ginsenoside, antioxidant activity, and anticancer effect of the cultivated wild Panax ginseng (CWP) have been conducted, there is little research on the effect of CWP extract on bone metabolism. In this study, we investigated the potential anti-osteoporotic properties of CWP on the growth and differentiation of MC3T3-E1 cells. CWP significantly increased the viability and proliferation of MC3T3-E1 cells. CWP activated intracellular alkaline phosphatase (ALP) activity in MC3T3-E1 cells. In addition, CWP increased the mineralized nodules in MC3T3-E1 cells. Furthermore, CWP increased the expression of genes such as Runx2, ALP, OPN and OCN associated with osteoblast growth and differentiation in a dose-dependent manner.

For the purpose of evaluating the biocompatability of 3 kinds of metallic materials frequently used in pediatric dentistry (stainless steel crown, orthodontic band, orthodontic wire), cellular and molecular studies, including cell growth and proliferation, screening of cell death with determination of types whether necrosis or apoptosis and changes in expressions of related signaling molecules were examined, using cultured human gingival fibroblasts (HGF-1), HGF-1 was cultured in Dulbecco's modified Eagle's medium. among which the 3rd to 6th generations of HGF-1 were used. The specimen were divided into stainless steel crown (R), band (B) and wire (W). The immunocytochemical study was done for the detection of anti-PCNA (proliferating cell nuclear antigen) labeling. With extracted protein, western blot was done for the detection of ERK1/2, JNK, and p38, using individual antibodies. Cultured cells proliferated, remarkably till 7 day and slightly at 11 day. There was no statistical significance in the counts of proliferating HGF-1 between control and experimental groups (p>0.05). Relative growth rates were no statistically significant difference between control and experimental groups (p>0.05). PCNA labeling indexes showing similar patterns in control and experimental groups. The expressions of ERK1 and ERK2, p38 were similar in control and experimental groups. The expression of JNK increased at 1st day, slightly decreased at 4th day and markedly increased at 7th and 11 day. Although the patterns of control and experimental groups were similar, the increased expressions of JNK at late period suggest a possible stress due to inhibited cell growth and proliferation, and worse culture condition. Conclusively, the 3 kinds of metal specimens used in this study did not induce cellular and molecular hazards during short term culture of HGF-1. But, for the better clinical stability, the establishment of long period culture and animal experiment was thought necessary.

Cnidium monnieri (L.) Cusson is distributed in China and Korea, and the fruit of C. monnieri is used as traditional Chinese medicine to treat carbuncle and pain in female genitalia. In this study, we examined the anti-proliferation and cell cycle arrest effects of ethanol extracts from C. monnieri (CME) in AGS gastric cancer cells. Our results show that CME suppressed cell proliferation and induced release of lactate dehydrogenase (LDH) in AGS cells by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay and LDH assay. Cell morphology was altered by CME in a dose-dependent manner. In order to identify the cell cycle arrest effects of CME, we investigated cell cycle analysis after CME treatment. In our results, CME induced cell cycle arrest at G1 phase. Protein kinase B (Akt) plays a major role in cell survival mechanisms such as growth, division, and metastasis. Akt protein regulates various downstream proteins such as glycogen synthase kinase-$3{\beta}$ (GSK-$3{\beta}$) and tumor protein p53 (p53). Expression levels of p-Akt, p-GSK-$3{\beta}$, p53, p21, cyclin E, and cyclin-dependent kinase 2 (CDK2) were determined by Western blot analysis. Protein levels of p-Akt, p-GSK-$3{\beta}$, and cyclin E were reduced while those of p53, p21, and p-CDK2 (T14/Y15) were elevated by CME. Moreover, treatment with CME, LY294002 (phosphoinositide 3-kinase/Akt inhibitor), BIO (GSK-$3{\beta}$ inhibitor), and Pifithrin-${\alpha}$ (p53 inhibitor) showed that cell cycle arrest effects were mediated through regulation of the Akt/GSK-$3{\beta}$/p53 signaling pathway. These results suggest that CME induces cell cycle arrest at G1 phase via the Akt/GSK-$3{\beta}$/p53 signaling pathway in AGS gastric cancer cells.

A previous study showed that krill oil improved recognition and memory through anti-oxidative effects in an amyloid β model, but the authors noted that further investigations are necessary of alterations to neurotransmitters' states and of serum lipid profile improvements related to serum lipid peroxidation. Accordingly, in this study, ICR mice were pre-treated intraperitoneally with scopolamine prior to induced neurotransmission impairment, and the effects of krill oil provision on their capabilities of cognition were tested by performing a passive avoidance test (PAT), water maze test (WMT), and novel object recognition test. Then, parameters including the acetylcholine (ACh) concentration, acetylcholinesterase activity (AChE), lipid peroxidation, serum lipid levels, and nerve cell proliferation were investigated. The results showed that krill oil improved the mice's abilities in recognition and memory as the times taken to complete the PAT and WMT were reduced compared to the mice in a comparison scopolamine-treated group. Krill oil produced an increased concentration of Ach, and this was accompanied by a decrease in AChE. As shown in a scopolamine-treated SH-SY5Y cell line, krill oil reduced the activity of AChE. Moreover, the suppression of lipid peroxidation-reflected in the finding that malondialdehyde was decreased with krill oil provision-is speculated to affect the recorded serum triglyceride and cholesterol decreases and LDL cholesterol increase. The intake of krill oil was also found to produce an improvement in brain-derived neurotrophic factor expression by stimulating the activation of cyclic AMP response element binding protein in the brain tissue. Overall, the current results imply that the provision of krill oil raises the cognition and memory by elevating neurotransmitters and by improving the serum lipid profile and nerve cell proliferation, which occur as lipid peroxidation is suppressed in the brain tissue.

Although significant progress has been made in the surgical treatment of esophageal carcinoma as well as in the detection of early stage esophageal carcinoma by diagnostic techniques, the prognosis of the esophageal carcinoma patients remain poor. The p53 gene product is known to regulate cell growth and proliferation. And the nm23 gene was identified originally as an anti-metastatic influence whose expression was correlated inversely with tumor metastatic potential in murine melanoma cell lines. This experiment was intended to know the relationship among the p53 and nm23 gene expression versus clinicopahologic characteristics of the esophageal cancer. Total 40 cases were collected from patients who had undergone esophagectomy at St. Mary's Hospital, Catholic university of Korea. Immunohistochemical stain for p53 mutant-type protein and nm23 protein was graded as <10% positive tumor cells: negative; 10∼30% positive tumor cells: + ; 30∼50% positive tumor cells: ++, and >50% positive tumor cells: +++. The tumor invasion was grades as none:- ; mild:+ ; moderate:++ ; severe: +++. Overexpression of p53 protein and nm23 was not associated with the survival and cliniocopathologic characteristics of the esophageal cancer. Moreover, the combination analysis of p53 and nm23 revealed that there was no relationship between the gene expression and the clinicopatholic characteristics of the esophageal cancer.
Objectives: This study was intended to clarify how Jakyakkamchobuja-tang (hereinafter referred to JKBT) affects mice of C57BL/10 whose osteoarthritis was induced by papain. Methods: Osteoarthritis was induced in mice by injecting papain in the knee joint. Mice were divided into 4 groups (n=6). The normal group were not treated at all whereas the control group (OAC-control) were induced for osteoarthritis by papain and oral medicated with 200 ul of physiological saline per day. The positive comparison group (OAC-$Joins^{(R)}$) were injected with papain and after 7 days, 100 mg/kg of $Joins^{(R)}$ were medicated with 200 ul of physiological saline mixed. The experimental group (OAC-JKBT) were injected with papain and after 7 days were medicated with 400 mg/kg of JKBT mixed with 200 ul of physiological saline. OAC-$Joins^{(R)}$ and OAC-JKBT were oral medicated for each substance for a total of 4 weeks, once per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the function of liver and kidney, inflammation cytokine values within serum, degree of revelation for inflammation cytokine genes, immune cells within blood, metabolism of arachidonic acid and amount of cartilage were measured and histopathological variations for knee joint structures were observed. Results: Functions of liver and kidney were not affected. IL-$1{\beta}$ (interleukin-$1{\beta}$), MCP-1 (monocyte chemoattractant protein-1) and TNF-${\alpha}$ (tumor necrosis factor-${\alpha}$) were significantly reduced and IL-6 (interleukin-6) was also reduced but not significantly. After analyzing inflammation cytokine in joints with mRNA (messenger ribonucleic acid), revelation of IL-6, TNF-${\alpha}$, COX-2 (cyclooxygenase-2) and iNOS-II (inducible nitric oxide synthase-II) were all significantly reduced. Revelation of IL-$1{\beta}$ gene was also reduced but not significantly. Neutrophil for WBC (white blood cell) within serum was significantly reduced; monocyte was also reduced but not significantly. PGE2 (prostaglandin E2), TXB2 (thromboxane B2) were significantly reduced and LTB4 (leukotriene B4) was also reduced but not significantly. Destruction of cartilage on micro CT (computed tomography)-arthrography was reduced but had no significant differences. In terms of histopathology, infiltration of inflammation, proliferation of synovial membrane, subsidence of cartilage and bone due to penetration of excessive formation of synovial cell and destruction of cartilage were small (H&E (hematoxylin and eosin), safranine O staining). Conclusions: Based on these results, Jakyakkamchobuja-tang (JKBT) is believed to be useful for suppressing the progress of osteoarthritis and its treatments because of its anti-inflammatory effects and alleviation of pain with histopathological effective efficacy.
