  • Various kinds of related parameters on hypertension such as anti-oxygen effect, ACE, weight of body, hwart and kidney, blood pressure, heartbeat rates, contents of aldosterone, catecholamine, change rates, of plasma constituents, uric acid, BUN, creatinine were determined to verify the effects on hypertension by Kamisamul-tang (KSMT). And the results are concluded as follows. KSMT did not show any cytotoxicity at the range of concentration (1-250 ${\mu}g/m{\ell}$) on the human fibroblast cell (hFCs). KSMT decreased the production of reactive oxygen species (ROS) and DPPH generation depending on the concentration. KSMT significantly inhibited angiotensin converting enzyme(ACE) activity depending on the concentration compared with control. KSMT maintained body weight of body, heat and kidney nearly normal group in hypertensive rat induced by DOCA-salt. KSMT significantly blood pressure and heart beat rate compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased aldosterone, dopamine, norepineph- rine, epinephrine compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of potassium and cloride compared with control wheareas increased that of calcium significantly in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of uric acid and BUN compared with control in hypertensive rat induced by DOCA-salt. It is verified experimentally tat Kamisamultang(KMST) which has been used broadly as a clinical therapeutics in oriental medicine is effective for anti-hypertension mechanism. And it could be applied to develope the reliable prescriptions for anti-hypertension in the future.

  • Objectives : Elastic fibers are found in the skin, lungs, arteries, veins and other structures. The defects of elastic matrix aggravate hypertension which is associated with alteration in the great arteries, arteries, and arterioles. The elastase inhibitors were undergoing in clinical studies about emphysema and pulmonary hypertension. This study was designed to investigate the effect of Astragali Radix extracts (AR) on elastase activity and anti-oxidative effects. Methods : The elastase inhibitory activity and DPPH (1,1-diphenyl-2-picrylhydrazyl) and NO free radical scavenging activities of AR were measured. Results : The elastase activity was significantly inhibited by AR. The significant DPPH and NO free radical scavenging activities were observed in AR as well. Conclusion : AR showed the anti-elastase effects and anti-oxidative activities in vitro. These results suggest that AR may be a possible drug for the treatment of pulmonary emphysema and pulmonary hypertension.

  • Ishige foliacea belongs to class Phaeophyceae and family Ishigeaceae. This study investigated the physiological activities of the Korean marine algae I. foliacea. Its solvent extracts were prepared with 70% ethanol, 80% methanol, and distilled water. The ethanol and methanol extracts had higher α-glucosidase (half-maximal inhibitory concentration, IC50: 0.67-0.73 mg/mL), xanthine oxidase (IC50: 0.25-0.28 mg/mL), and angiotensin-converting enzyme (IC50: 25.29-38.28 ㎍/mL) inhibitory activities than those of the water extract. The ethanol and methanol extracts possessed high acetylcholinesterase inhibitory activity (IC50: 0.78c0.97 mg/mL). Conversely, the water extract exhibited the highest β-secretase inhibitory activity (IC50: 0.48 mg/mL). These results indicate that I. foliacea may be useful as a functional substance in food and pharmaceuticals with anti-diabetic, anti-gout, anti-hypertension, and anti-dementia properties.

  • In oriental medicine, Gamibangpungtongsungsan (KBTS) has been used as a therapeutic agent for the treatments of acute stage of cerebrovascular diseases and hypertension. In the present study, underlying mechanism on KBTS effects was investigated using spontaneously hypertensive rats (SHR) by determining related parameters such as blood pressure, heart-beat rates, and hormones and plasma constituents. The major finding are summarized as follows. 1. KBTS treatment at concentrations lower than $125\;{\mu}g/m{\ell}$ did not show any cytotoxicity on cultured human fibroblast cells. 2. KBTS treatment in SHR significantly decreased blood pressure and heart-beat rate compared with untreated control. 3. KBTS treatment in SHR decreased aldosterone levels in the blood compared with untreated control, but the difference was not statistically significant. 4. KBTS treatment in SHR significantly decreased dopamine, norepinephrine and epinephrine levels in the blood compared with untreated control. 5. KBTS treatment in SHR decreased plasma ion concentrations such as Na+, K+, Ca2+, Cl- compared with untreated control; decreases in Na+ and Cl- were statistically significant. 6. KBTS treatment in SHR significantly decreased TNF-$\alpha$, IL-6, and IL-10 levels in the blood compared with untreated control. Thus, the present data show evidence on anti-hypertension activity of KBTS in an experimental animal system, which can provide further insights into the development of anti-hypertension therapeutic agents.

  • Verapamil is a calcium channel blocker and is classified as a class IV anti-arrhythmic agent. It is used in the control of supra ventricular tachyarrhythmias, and in the management of classical and variant angina pectoris. It is also used in the treatment of hypertension and used as an important therapeutic agent for angina pectoris, ischemic heart disease, hypertension and hypertrophic cardiomyopathy. Verapamil commonly co-administered with NSAIDs (non-steroidal anti-inflammatory drugs) i.e. diclofenac sodium, flurbiprofen, Ibuprofen, mefanamic acid and meloxicam. A simple and rapid RP-HPLC method for simultaneous determination and quantification of verapamil and NSAIDs was developed and validated. The mobile phase constituted of acetonitrile: water (55:45) whose pH was adjusted at 2.7 and pumped at a flow rate of 2.0 mL $min^{-1}$ at 230 nm. The proposed method is simple, precise, accurate, low cost and least time consuming for the simultaneous determination of verapamil and NSAIDs which can be effectively applied for the analysis of human serum.

  • This study was attempted to investigate the anti-hypertensive activity of Solanum tuberosum, cv. Gui valley. Ethanol extract of Gui vally (EGV) increased free radical scarvenge activity up to 91.6% of control at $200{\mu}g/m{\ell}$. It's anti-oxidant activity is similar to 10 uM of ascorbic acid, well known as antioxidant. EGV inhibited Angiotensin-I-converting enzyme (ACE) activity in vitro. ACE plays a important role in regulation of blood pressure and ACE inhibitors are important for the treatment of hypertension. Anti-hypertensive activity of EGV in vivo was assessed in lead acetate (LAT)-induced hypertensive rats for 8 weeks. Elevated blood pressure in control group was significantly decreased by EGV at 200 mg/kg. Also, ACE activity in blood was also suppressed by EGV treatment. Taken together, these results suggest that EGV has an anti-hypersive activity via inhibition of ACE and can be used for the treatment or prevention of hypertension.

  • The fruits of Eleutherococcus sessiliflorus (Rupr. & Maxim.) S. Y. Hu (Araliaceae), as edible fruits, were traditionally used for ingredients of wine or tea in Eastern Asia. In addition to, the fruits of E. sessiliflorus were known for having antioxidant and anti-inflammatory effects. Recently, we investigated that the ethanolic extracts of E. sessiliflorus fruits (DHP1501) have effects on hypertension via vasorelaxation and decrease of blood pressure. In the present study, we investigated that the gene and protein expression levels of endothelial nitric oxide synthase (eNOS) was increased by treatment of DHP1501 in HUVECs. Moreover, we confirmed the angiotensin converting enzyme inhibitory activity of DHP1501 through in vitro tasks. Therefore, DHP1501 could be a candidate of functional food for alleviating hypertension.

  • Elastic fibers are found in the skin, lungs, arteries, veins and other structures. Elastases destroy the elastic fibers and cause the emphysema and pulmonary hypertension. Oxidative stress is needed for these pathologic changes. Accordingly, present study was designed to investigate the effect of Albizziae Cortex extracts (ACE) on elastase activity and anti-oxidative effects of ACE. The in vitro inhibitory effects on elastase and di(phenyl)-(2,4,6-trinitrophenyl)iminoazanium (DPPH) and nitric oxide (NO) free radical scavenging activities of ACE were measured. The elastase activity was significantly inhibited by ACE. DPPH and NO free radicals were significantly scavenged as well. ACE showed the elastase-inhibiting effects and anti-oxidative activities in vitro. These results suggest that ACE may have potential roles in the treatment of pulmonary emphysema and pulmonary hypertension.

  • In spite of the fact that a variety of unfailing guidelines are existing for the management of hypertension, the problem of inadequate managing of this condition still continues. Several classes of existing antihypertensive drugs are associated with various side-effects. Since ancient times before the advent of anti-hypertensive drugs, this disease has been treated by the prominent classical scholars. Various herbal drugs are being used since ages for the treatment of hypertension and some of them are validated too. Evolvulus alsinoides is also one such herb used in classical literature since ages for various disorders like insanity, anxiety, nervous debility, epilepsy, melancholy, palpitation and many others. This review is to highlight the antihypertensive potential of Evolvulus alsinoides.

  • Obesity increases the risk of developing metabolic diseases such as hypertension, type 2 diabetes, hyperlipidemia, and cardiovascular diseases, as well as some cancers. To prevent the occurrence of these diseases and death, it is essential to manage obesity. Though there are several treatments for obesity, lifestyle interventions, such as diet and exercise, and drug therapy are most widely used in clinical practice. Among the anti-obesity drugs available, the weight loss effect of naltrexone/bupropion has been well-proven. We present a case study in which naltrexone/bupropion, a glucagon-like peptide-1 agonist, and a sodium-glucose transporter 2 inhibitor showed significant weight loss and improved metabolic parameters. Additionally, the management of type 2 diabetes and hypertension, which are common diseases in patients with obesity, was also included.
