        Plantago asiatica L., observed frequently in East Asia, is a known herb used in traditional medical remedies several studies report that P. asiatica L has anti-inflammatory and antioxidant effects. To determine the production of cytokines (IL-2, IFN-γ, and TNF-α) induced by lipopolysaccharide (LPS) and non-LPS-stimulated macrophages, an ELISA assay was conducted using cytokine kits. Mice splenocytes were cultured for 48 h with various concentrations of P. asiatica L. (5, 10, 50, 100, 250, 500, and 1,000 μg/mL) or with mitogens (ConA or LPS). P. asiatica L. increased the proliferation of mice splenocytes, especially under the condition of its concentration ranging from 250 to 1,000 μg/mL. In addition, Plantago asiatica L. notably induced cytokine production of (IL-2, IFN-γ, and TNF-α) at its concentration of 250~500 μg/mL. These results suggest that supplementation with P. asiatica L. water extracts may play a potential role in enhancing immune function by mediating splenocyte proliferation and cytokine production through its anti-inflammatory activit.

        Plantago asiatica L. (P. asiatica) has been used as one of the popular folk medicines in Asia for human health care practices. Various activities of P. asiatica have been reported, such as anti-oxidant, anti-glycation,anti-inflammatory and hepatoprotective activity. Therefore, the potential of P. asiatica to reduce oxidative stress has been studied in several ways for over 20 years, especially at liver and kidney. However no investigation has been reported revealing its protective effect on prostate. Method : Treatment of P. asiatica leaf ethanolic extract (PLE) (1 g/kg body weight (b.w.), 2 g/kg b.w., or 4 g/kg b.w.) were given separately to animals for pretreatment once per day for 7days, and on the seventh day ferric nitrilotriacetate (Fe-NTA; 0.24 mmol Fe/kg b.w.), which is known as an oxidative stress-inducer at prostate, was administrated by i.p to negative control group. At the end of the study period, dissection was carried out for detecting the prostate protective effect of PLE. Result : Fe-NTA-treated animals produced reactive oxygen species (ROS) resulting in depletion of antioxidant biomaker, such as glutathione (GSH), glutathione reductase (GR), and glutathione s-transferase (GST) and increase of lipid peroxidation in prostate. However, PLE pretreatment resulted in an increase in the GSH, GST and GR levels concentration dependent manner and in an significant decrease in the levels of lipid peroxidation. Conclusion : Our data suggest that PLE may be effective in protecting oxidative stress-induced damage of prostate, and PLE may be an chemopreventive agent against Fe-NTA-mediated prostate oxidative damage.

        Plantago asiatica L. (PA), which is widely distributed in Korea, Japan and China, has traditionally been used as a popular folk medicine for the treatment of liver diseases. A variety of activities of PA was reported, that is hepatoprotective, anti-inflammatory, anti-glycation and anti-oxidant effect. Ferric nitrilotriacetate (Fe-NTA) is a potent nephrotoxic agent and has been reported to induce renal proximal tubular necrosis. In the present study, pretreatment with PA extract (PAE) in Wistar rat followed by Fe-NTA i.p. treatment (13.5 mg Fe/kg body weight) was performed to detect the renal protective effect of PAE. Only Fe-NTA treated group showed increases in the level of serum blood urea nitrogen (BUN) and serum creatinine (Cr), and renal tissue malondialdehyde (MDA), product of lipid peroxidation. Moreover, the level of biomarkers indicate the antioxidants status, reduced glutathione (GSH), glutathione-S-transferase (GST) and glutathione reductase (GR) were decreased. However, PAE pre-treated group showed decreases in the levels of serum BUN, serum Cr and renal tissue MDA in concentration dependent manner and increases in the level of GSH, GST and GR. These results are significantly different (p < 0.05) to the other groups. Our data suggest that PAE may be used as an chemopreventive material against Fe-NTA-mediated renal oxidative stress.

        Toxoplasmosis is an important cause of foodborne, inflammatory illnesses, as well as congenital abnormalities. Currently available therapies are ineffective for persistent chronic disease and congenital toxoplasmosis or have severe side effects which may result in life-threatening complications. There is an urgent need for safe and effective therapies to eliminate or treat this cosmopolitan infectious disease. The aim of this study was to investigate the in vitro anti-Toxoplasma activities of Plantago asiatica L., one of the herbal extracts, using tachyzoit of T. gondii RH strain infected HeLa cells. As the results, the selectivity of Plantago asiatica L. extract was 4.5, which was higher than Sulfadiazine selectivity (0.4). Also, we perfomed the cell proliferation inhibition test and the morphological study to evaluate the anti-T. gondii activity of Plantago asiatica L. extract with HeLa cells. As the results, the inhibition rate of the Plantago asiatica L. extract was high inhibition rate. This indicates that the Plantago asiatica L. extract may be used for new anti-T. gondii agent.
