  • The present study investigated whether electroacupuncture (EA) can alleviate hypertension and concomitant disorders such as decreased kidney weight and elevation of serum creatinine in spontaneous hypertensive rats. EA (2 Hz, 3 mA, 10 min) was applied to Joksamni (ST36) once daily for 7 days. Body weight, blood pressure and heart rate were measured on Day 0, 2, 6, 8, 10 and 12, and kidney weight and serum creatinine levels were examined after sacrifice (on Day 12 after last examination). In the ST36 group, the blood pressure were significantly decreased from 6thdays and its effects lasted up to Day12 (up to 5days after cessation of acupuncture), compared to control. And, significant decreases of the heart rates after EA at ST36 were also observed on Day 2, 6, and 8. However, there were no significant differences in daily body weight, kidney weight and serum creatinine between acupuncture and control group. These results showed that EA at ST36 caused anti-hypertension by decreasing blood pressure and heart rates in spontaneous hypertenstive rats, although it failed to alleviate concomitant disorders such as the decreased kidney weight and elevation of serum creatinine shown in hypertensive rats.

  • Oxidative stress and inflammation are important events in the development of chronic inflammatory diseases including arthritis, atherosclerosis, diabetes, hypertension. Cynomorium songaricum (CS) has been used as a traditional Korean herbal medicine, and it is currently used in traditional clinics to treat frequent urination, spermatorrhea, weakness of the sinews and constipation in the folk medicine. The aim of this study was to determine whether fractionated extracts of CS inhibit free radical generation such as DPPH radical, superoxide radical, nitric oxide and peroxynitrite, production of nitrite an index of NO, $PGE_2$, iNOS, COX-2 and pro-inflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. Cytotoxic activity of extracts on RAW 264.7 cells was measured using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Our results indicated that the most superior extract which scavenged DPPH radical, reactive oxygen species (ROS) and RNS was CS ethyl acetate extract (CSEA). Moreover, CSEA significantly inhibited the LPS-induced NO, $PGE_2$ production and iNOS, COX-2 expression accompanied by an attenuation of TNF-$\alpha$, IL-$1{\beta}$ and IL-6 formation in macrophages. Furthermore, CSEA treatment also blocked LPS-induced intracellular ROS production and the activation of NF-${\kappa}B$. These findings indicate that CSEA inhibits the production of pro-inflammatory mediators and cytokines via the suppression of ROS production and NF-${\kappa}B$ activation. Take together, these results indicate that CSEA has the potential for use as an natural anti-oxidant and an agent of anti-chronic inflammatory diseases.

  • Purpose: This analysis was conducted to evaluate cardiovascular toxicity of commonly used anti-VEGF therapeutic agent, bevacizumab, in treating patients with cancer. Methods: Clinical studies evaluating the efficacy and safety of bevacizumab-based regimens on response and safety for patients with cancer were identified using a predefined search strategy, allowing cardiovascular toxicity and other side effects of treatment to be estimated. Results: In bevacizumab based regimens, 4 clinical studies including 282 patients with advanced cancer (including gliomas, cervical, breast and ovarian cancer) were considered eligible for inclusion. These bevacizumab-based regimens included docetaxel, irinitecan and carboplatin. Systematic analysis suggested that, of 282 patients treated by bevacizumab based regimens, hypertension and thrombo-embolism occurred in 2.5% (7/282), while only 3 patients reported cardiovascular events (1.1%). No treatment related death occurred in bevacizumab based treatment. Conclusion: This systemic analysis suggests that bevacizumab based regimens are associated with reasonable and accepted cardiovascular toxicity when treating patients with gliomas, cervical, breast and ovarian cancer.

  • Clerodendrum trichotomum is a folk medicine exhibiting anti-hypertension, anti-arthritis, and anti-rheumatism properties. However, little is known about whether the material might prevent hyperuricemia and associated inflammation. In this study, we explored whether C. trichotomum leaf extract (CTE) prevented hyperuricemia induced by potassium oxonate (PO) in mice. CTE (400 mg/kg body weight) significantly reduced the serum uric acid (UA), blood urea nitrogen (BUN), and serum creatinine levels and increased urine UA and creatinine levels. CTE ameliorated PO-induced inflammation and apoptosis by reducing the levels of relevant proteins in kidney tissues. Also, CTE ameliorated both UA-induced inflammatory response in RAW 263.7 cells and UA-induced cytotoxicity in HK-2 cells. In addition, liver transcriptome analysis showed that CTE enriched mainly the genes for mediating positive regulation of MAPK cascade and apoptotic signaling pathways. Together, the results show that CTE effectively prevents hyperuricemia and associated inflammation in PO-induced mice.

  • This study was performed to investigate the physicochemical activities such as mineral contents, antioxidantant activities, ${\partial}$-glucosidase activity, and angiotensin I-converting enzyme(ACE) inhibitory effect of Dangmyon (starch vermicelli) prepared with mulberry leaves powder. Mulberry leaves powder was added in ratio (w/w) of 0% (CON), 0.5% (MD1), 1.0% (MD2), 1.5% (MD3), and 2.0% (MD4), and then mineral contents, total polyphenol contents, antioxidant, antidiabetic, and antihypertensive activities of the Dangmyon were measured. The mineral contents were significantly increased by the addition of mulberry leaves powder (p<0.001). The total polyphenol contents and antioxidant activities of Dangmyon were significantly increased by the addition of mulberry leaves powder (p<0.05). In terms of antidiabetic and antihypertensive activities showed MD1~MD4 samples higher contents of ACE and ${\alpha}$-glucosidase compared to control (p<0.05). Our findings suggest that addition of mulberry leaves powder to Dangmyon may improve the effects of anti-oxidation, anti-DM, and anti-hypertension and provide health benefits of consumers.

  • Obesity increases the risk of mortality and morbidity because it results in hypertension, heart disease, and type 2 diabetes. Therefore, there is an urgent need for pharmacotherapeutic drugs to treat obesity. We performed a screening assay using natural products with anti-adipogenic properties in 3T3-L1 cells and determined that tschimganidine, a terpenoid from the Umbelliferae family, inhibited adipogenesis. To evaluate the anti-obesity effects of tschimganidine in vivo. Mice were fed either a normal chow diet (NFD) or a high-fat chow diet (HFD) with or without tschimganidine for 12 weeks. Treatment with tschimganidine decreased lipid accumulation and adipogenesis, accompanied by reduced expression of adipogenesis and lipid accumulation-related factors. Tschimganidine significantly increased the phosphorylation of AMP-activated protein kinase (AMPK) and decreased that of AKT. Depletion of AMPK relieved the reduction in lipid accumulation resulting from tschimganidine treatment. Moreover, tschimganidine administration drastically reduced the weight and size of both gonadal white adipose tissue (WAT) and blood glucose levels in high-fat diet-induced obese mice. We suggest that tschimganidine is a potent anti-obesity agent, which impedes adipogenesis and improves glucose homeostasis. Tschimganidine can then be evaluated for clinical application as a therapeutic agent.
