Crude extracts or phytochemicals obtained from some plants have potential anti-cancer properties. Teucrium persicum is an Iranian endemic plant belonging to the Lamiaceae family which has traditionally been used to relieve abdominal pains. However, the anti-cancer properties of this species of the Teucrium genus have not been investigated previously. In this study, we have used a highly invasive prostate cancer cell line, PC-3, which is an appropriate cell system to study anti-tumor properties of plants. A methanolic extract obtained from T persicum potently inhibited viability of PC-3 cells. The viability of SW480 colon and T47D breast cancer cells was also significantly decreased in the presence of the T persicum extract. Flow cytometry suggested that the reduction of cell viability was due to induction of apoptosis. In addition, the results of wound healing and gelatin zymography experiments supported anti-cell invasion activity of T persicum. Interestingly, sublethal concentrations of T persicum extract induced an epithelial-like morphology in a subpopulation of cells with an increase in E-Cadherin and ${\beta}$-Catenin protein levels at the cell membrane. These results strongly suggest that T persicum is a plant with very potent anti-tumor activity.

Water-soluble crude polysaccharide (TM-1) prepared from the leaves of Teucrium viscidum var. miquelianum was fractionated into three polysaccharide fractions, TM-2, TM-3 and TM-4 by the addition of cetyltrimethylammonium bromide. The major polysaccharide fraction, TM-2, consisted of glucose, galactose, rhamnose, mannose, glucuronic acid and galacturonic acid, and all fractions contained galactose and glutose as the major neutral sugars. TM-4 showed the highest anti-complementary activity. When TM-4 was futher fractionated by anion exchange chromatography, TM4- II a and TM4-II b showed the most Potent anti-complementary activity. TM4- II a was composed mainly of galactose, arabinose and glucose in the molar ratios of 2.13 : 0.94 : 1.00 respectively, and contained a small amount of galacturonic acid and glucuronic acid.

Objectives: Myocardial reperfusion is the only logical cure for ischemic heart disease. However, ischemic-reperfusion (I/R) injury is one of the underlying factors facilitating and accelerating the apoptosis in the myocardium. This study set to investigate the impact of Teucrium polium (TP) hydro-alcoholic extract on I/R induced apoptosis in the isolated rat heart. Methods: Isolated rat hearts were classified into six groups. The control samples were subjected to 80 min of perfusion with Krebs-Henseleit bicarbonate (KHB) buffer; in control-ischemia group, after primary perfusion (20 min) the hearts were exposed to global ischemia (20 min) and reperfusion (40 min). Pretreated groups were perfused with $500{\mu}M$ of vitamin C and various TP concentrations (0.5, 1, 2 mg/ml) for 20 min, and then the hearts were exposed to ischemia and reperfusion for 20 min and 40 min, respectively. Cardiodynamic parameters including rate pressure product (RPP), heart rate (HR), the maximum up/down rate of left ventricular pressure (${\pm}dp/dt$), left ventricular developed pressure (LVDP), and coronary artery flow (CF) were achieved from Lab Chart software data. The Bax and BCl-2 gene expressions were measured in heart samples. Results: Hearts treated with TP extract and vit C represented a meaningful improvement in cardiac contractile function and CF. The overexpression of Bcl-2, downregulation of Bax, and improvement of apoptotic index (Bax/Bcl-2) were observed in pretreated TP extract and vit C hearts. Conclusion: The TP extract was found to ameliorate the cardiac function in the reperfused myocardium. Also, it can hinder apoptotic pathways causing cardioprotection.

The purpose of this study was to examine the biological activities of gamma-irradiated Teucrium veronicoides. In photostimulated luminescence analysis, non-irradiated sample showed lower than 700 photon counts (PCs), whereas irradiated (5 and 10 kGy) samples showed higher than 700 PCs. The thermoluminescence ratio of non-irradiated samples was less than 0.1, whereas the values of irradiated samples were greater than 0.1. Electron spin resonance analysis was performed confirmed for irradiation identification. The total phenolic contents of hot-water and 50% ethanol extracts were higher than those values after irradiation at 10 kGy. Regarding 1,1-diphenyl-2-picrylhydrazyl radical inhibitory activity, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, antioxidant protection factor, thiobarbituric acid reactive substance inhibitory activity as antioxidant test and xanthine oxidase inhibitory activity, the effect of gamma irradiation had on significant effects. On the other hand, ${\alpha}-amylase$ inhibitory activity of 10 kGy-irradiated hot-water extract was 23.6% higher than that of the non-irradiated sample. Thus, gamma irradiation could be used for the long-term storage of Teucrium veronicoides.

Objectives : The purpose of this paper was to investigate the anti-inflammatory effects of extract from Teucrium veronicoides (TV) on the RAW 264.7 cells. Methods : To evaluate of anti-inflammatory of TV, we examined the cytokine productions on lipopolysacchride (LPS)-induced RAW 264.7 cells and also inhibitory mechanisms using Western blot. Furthermore, We examined LPS-induced endotoxin shock. Results : 1. Extract from TV itself does not have any cytotoxic effect. 2. Extract from TV reduced LPS-induced Nitric oxide (NO),interleukin (IL)-1b, IL-6 and IL-10, tumor necrosis factor-a (TNF-a) production in RAW 264.7 cells. 3. TV inhibited the activation of mitogen-activated protein kinases (MAPKs) such as p38, extracelluar signal-regulated kinase (ERK 1/2) and c-Jun NH2-terminal kinase (JNK) and also the degradation of inhibitory kappa B a (Ik-Ba) in the LPS-stimulated RAW 264.7 cells. 3. TV slightly increased the duration of survival after LPS-induced endotoxin shock. Conclusions : TV down-regulated LPS-induced NO and cytokines production, which could provide a clinical basis for anti-inflammatory properties of TV.

1. Objective : The purpose of this study is to understand the origin, changes and composition of Soeumin's Bojungikgi-tang. 2. Methods : 1) Analyzed the context of the progressive transformation of soeumin's Bojungikgi-tang in related passages from "Donguibogam (東醫寶鑑)", "Donguisusebowon Chobongwon (東醫壽世保元 草本卷)", "Donguisusebowon Gabobon (東醫壽世保元 甲午 本)", "Donguisusebowon Sinchukbon (東醫壽世保元 辛丑本)", "Dongmuyugo (東武遺稿)" 2) Examined the differences between the utilization of Soeumin's Bojungikgi-tang in pre-existing manuscripts according to pathological pattern and more specifically at a pathological stage. 3) Analyzed the total primary effect of the herbs as a prescriptive category, as well as the herbal properties of each component. 3. Results and Conclusions : 1) Originally Dongwon's Bojungikgi-tang was prescribed as a stomach & spleen organ tonifying medicine so it was easily applied and established as a prescription appropriate for Soeumin constitutional types with a weaker spleen organ. 2) From Gabobon(甲午本), Soeumin's Bojungikgi-tang was modified, excluding Bupleurum falcatum(柴胡), Cimicifuga heracleifolia (升麻) and substituting Teucrium chamaedrys(藿香), Ophiopogon japonicus(蘇葉) which are herbs appropriate for the Soeumin constitutional type. 3) In the Gabobon(甲午本), the Gegi-tang which has yang raising properties is included in the Soeumin's Bojungikgi-tang. In Sinchukbon(辛丑本), the Gegi-tang of the Soeumin's Bojungikgi-tang in the Gabobon was excluded and the Gegi-tang mutated into Hwangigyeji-tang. 4) In the Gabobon(甲午本), as the Soeumin's Bojungikgi-tang was prescribed for Soeumin disease regardless of favorable-unfavorable patterns and mild-severe patterns, the stage of the disease when to prescribe Soeumin's Bojungikgi-tang was not clarified. 5) As of the Sinchukbon(辛丑本) edition, as Soeumin's prescriptions have been obvious, the soeumin's Bojungikgi-tang was applied to Mang-yang disease with Hwangigyeji-tang and Seungyangikki-tang 6) As of the Sinchukbon(辛丑本) edition, the Soeumin's Bojungikgi-tang has been applied to parients having both exterior-heat Mang-yang disease and Greater-yin disease, at the same time. 7) As of the Sinchukbon(辛丑本) edition, finally, the Soeumin's Bojungikgi-tang formula has been established as gathering Qi and middle tonification with Panax ginseng(人蔘), Astragalus membranaceus(黃芪), keeping the spleen healthy with Artractylodes japonica(白朮), keeping the spleen strong with Angelica acutiloba(當歸), rooting the spleen with Citrus reticulata(陳皮), raising Yang and middle jiao with Teucrium chamaedrys(藿香), Ophiopogon japonicus(蘇葉), middle tonification with Glycyrrhiza glabra(甘草灸), Zingiber officinale(生薑), Zizyphus jujuba(大棗).

Pastures of the Apennines of Central Italy contribute to feed resources of high altitude (above 1,300 m sea level) grazing systems. The objective of this study was to evaluate the effectiveness of faecal extract from the yak (Bos grunnienes) as an alternative microbial inoculum to rumen fluid for estimation of digestibility of several forage species. Forage samples produced at high altitude were tested in this study: four legumes (Lathyrus sativus L., Lotus corniculatus L., Onobrychis viciaefolia L. and Trifolium pratense L.), three forbs (Achillea millefolium L., Potentilla reptans L. and Teucrium flavum L.) and one grass (Brachipodyum pinnatum L.) were incubated with yak rumen fluid or faecal extract. A large variability in chemical composition was observed among the species collected. Rumen liquor and faecal samples were collected from adult healthy yak. The $Daisy^{II}$ incubator was used to evaluate the nutrient digestibility of forages using rumen liquor as control and faecal extract as alternative microbial inoculum sources. Filter bags containing samples of browse species were added to the four digestion vessels along with their respective inoculum and then incubated for 48 h and dry matter (DM), organic matter (OM), crude protein (CP), neutral and detergent fiber (NDF) digestibility was determined. There was a significant relationship between estimates, indicating that faecal liquor has the potential to be used instead of rumen fluid for estimation of in vitro digestibility of plants. It is concluded that the $Daisy^{II}$ incubator results are appropriate for the determination of in vitro digestibility of nutrients using faecal liquor to define the potential for adaptation of yak to new pastures.
