People with hypertension (high blood pressure) are at an increased risk of suffering from glaucoma, a condition in which the pressure within the eye increases. Its noted that several antihypertensive are found to be useful in lowering the intraocular pressure, this review throws some light on the use of these antihypertensives as antiglaucoma drugs and about their probable mechanisms.

Liriodendrin, m. p. $269-270^{\circ}$, $C_{22}$ $H_{46}$ $O_8$ as one of the antihypertensive components was obtained from the cortex of Kalopanax pictum. Acid hydrolysis of liriodendrin yielided liriresinol-A, -B and glucose. The stereochemistry of liriodendrin was established by the NMR spectrum of liriodrin octaacelate. The NMR spectrum of liriodendrin octaacetate showed that $di-{\beta}-glucoside$ of lirioresinol-B type occurs in nature.

Objectives: The objective of this study was to estimate the risk of lung cancer in relation to angiotensin II receptor blocker (ARB) use among patients with hypertension from the Korean National Health Insurance Service-National Health Screening Cohort. Methods: We conducted a retrospective cohort study of patients with hypertension who started to take antihypertensive medications and had a treatment period of at least 6 months. We calculated the weighted hazard ratios (HRs) and their 95% confidence intervals (CIs) of lung cancer associated with ARB use compared with calcium channel blocker (CCB) use using inverse probability treatment weighting. Results: Among a total of 60 469 subjects with a median follow-up time of 7.8 years, 476 cases of lung cancer were identified. ARB use had a protective effect on lung cancer compared with CCB use (HR, 0.75; 95% CI, 0.59 to 0.96). Consistent findings were found in analyses considering patients who changed or discontinued their medication (HR, 0.50; 95% CI, 0.32 to 0.77), as well as for women (HR, 0.56; 95% CI, 0.34 to 0.93), patients without chronic obstructive pulmonary disease (HR, 0.75; 95% CI, 0.56 to 1.00), never-smokers (HR, 0.64; 95% CI, 0.42 to 0.99), and non-drinkers (HR, 0.69; 95% CI, 0.49 to 0.97). In analyses with different comparison antihypertensive medications, the overall protective effects of ARBs on lung cancer risk remained consistent. Conclusions: The results of the present study suggest that ARBs could decrease the risk of lung cancer. More evidence is needed to establish the causal effect of ARBs on the incidence of lung cancer.

The study was carried out to investigate a new type of functional foods with hypotensive effect which is critical in the prevention and treatment of hypertension and related circulatory diseases. The experimental diets(A, B, C) were prepared from plant based ingredients such as buckwheat, potato, perilla seed with different ratios formulated as an edible form appropriate for human consumption according to AIN-77 standard. Control group(D) was fed commercial rat chow. Twety-four 15-week-old SDR(Sprague Dawley rats) and twenty-four 20-week-old SHR(spontaneously hypertensive rats), weighing 200g respectively, were assigned to 4 treatments of 6 rats each in a completely randomized design. Blood pressure was measured at 7 day interval by tail-cuff sphygmomanometer using an IITC cuff pump and amplifier. The growth rates of both SHR and SDR were not statistically different in comparions with the control except those of diet B and C in SDR and SHR, respectively(p<0.05). When exprimental diets were fed, systolic blood pressure of SDR and SHR at day 28 had been lowered by 17-20 mmHg(ave. of 19.6mmHg for both strains) compared with the reference pressure at day 0. The levels of HDL-cholesterol were increased, while the levels of LDL-cholesterol consistently decreased in both strains when experimental diets were fed(p<.05). Plasma total cholesterol levels were not different among treatments. Plasma triglyceride levels were higher in control diet(commercial rat chow) due to two times higher fat content of control diet itself(p<.05). Atherogenic indices were lower compared to those of control when the experimental diets were fed in both strains (p,.05). The results suggest that the antihypertensive diets mainly consisting of plant-based ingredients may possibly effective in relieving hypertension as well as circulatory diseases.

Objectives : The purpose of the study was to determine the effects of a 4 weeks Meridian Tai Ji exercise treatment on blood pressure reducing in hypertensive patients. Methods : We measured the blood pressure of 3 patients who were visited in the Gwacheon Health center from 21th November 2007 to 17th December 2007. Eligible participants had systolic blood pressure ${\geq}$ 120 mmHg or diastolic blood pressure ${\geq}$ 80 mmHg with antihypertensive drug. Blood pressure measurements were after the patient had been in rest for at least 10 minute. Twelve sessions of Meridian Tai Ji exercise treatment over 4 weeks were performed in the patients. Blood pressure were measured twice before and after each session. Results : After 4 weeks, blood pressure reduction was observed in the treatment patients, with an average decline of systolic blood pressure up to 5.67 mmHg and diastolic blood pressure up to 0.17 mmHg. But, it was not statistically significant. Blood pressure increased between measurements taken before and after an Meridian Tai Ji exercise treatment session, although individual responses were quite variable. No significant difference was found in the immediate effect. Conclusion : Twelve sessions of Meridian Tai Ji exercise treatment do not seem to control hypertension. Further research is required to determine whether Meridian Tai Ji exercise treatment can enhance clinical management of hypertension if it is used in combination with more enrolled participants, over longer periods, or randomized controlled trial.

We characterized the probiotic properties of Lactobacillus helveticus strains KII13 and KHI1 isolated from fermented cow milk by in vitro and in vivo studies. The strains exhibited tolerance to simulated orogastrointestinal condition, adherence to Caco-2 cells, and antimicrobial activity. Both L. helveticus strains produced bioactive tripeptides, isoleucylprolyl-proline and valyl-prolyl-proline, during fermentation of milk. KII13 showed higher in vitro cholesterol-lowering activity (47%) compared with KHI1 (28%) and L. helveticus ATCC 15009 (22%), and hence, it was selected for in vivo study of cholesterol-lowering activity in atherogenic diet-fed hypercholesterolemic mice. For the study, mice were divided into four groups (viz., normal diet control group, atherogenic diet control group (HCD), KII13-atherogenic diet group (HCD-KII13), and Lactobacillus acidophilus ATCC 43121-atherogenic diet group (HCD-L.ac) as positive control). The serum total cholesterol level was significantly decreased by 8.6% and 7.78% in the HCD-KII13 and HCD-L.ac groups (p < 0.05), respectively, compared with the HCD group. Low-density lipoprotein cholesterol levels in both HCD-KII13 and HCD-L.ac groups were decreased by 13% and 11%, respectively, compared with the HCD group (both, p < 0.05). Analysis of cholesterol metabolism-related gene expression in mice liver showed increased expression of LDLR and SREBF2 genes in mice fed with KII13. By comparing all the results, we conclude that L. helveticus KII13 could be used as a potential probiotic strain to produce antihypertensive peptides and reduce serum cholesterol.

The dried roots of Danshen (Salvia miltiorrhiza) and Sanchi (Panax notoginseng) have been widely used in traditional Chinese medicine for promoting blood circulation as well as various other bodily functions. Here we investigated the effects of a mixture of aqueous extracts of Danshen and Sanchi, named PASEL, on blood pressure and vascular contractility in rats. Orally administered PASEL (62.5 mg/kg and 250 mg/kg, for 5 weeks) lowered the blood pressure of spontaneous hypertensive rats (SHR) but this was not observed in normal Wistar-Kyoto rats (WKR). We then investigated the effects of PASEL on the arterial contraction of the small branches of cerebral arteries (CAs) and large conduit femoral arteries (FAs) in rats. PASEL did not affect high-K (KCI 60 mM)- or phenyleprine (PhE)-induced contracture of FAs. The myogenic response, a reactive arterial constriction in response to increased luminal pressure, of small CA was dose-dependently suppressed by PASEL in SHR as well as control rats. Interestingly, the KCI-induced contraction of small CAs was slowly reversed by PASEL, and this effect was more prominent in SHR than control WKR. PASEL did not inhibit angiotensin-converting enzyme (ACE) activity. These results demonstrated that the antihypertensive effect of PASEL might be primarily mediated by altering the arterial MR, not by direct inhibition of L-type $Ca^{2+}$ channels or by ACE inhibition.
