    Abstract Stimulation of α2-adrenoceptor/I1-imidazoline receptors in the rostral ventrolateral medulla decreases the blood pressure via sympathoinhibition. However, alteration of receptor responses in genetically hypertensive rats remains unclear. We examined cardiovascular responses of α2-adrenoceptor/I1-imidazoline receptor agonist and antagonists microinjected into the rostral ventrolateral medulla of conscious spontaneously hypertensive rats and normotensive Wistar Kyoto rats. Injection of 2-nmol clonidine-an α2-adrenoceptor/I1-imidazoline receptor agonist-unilaterally into the rostral ventrolateral medulla decreased the blood pressure, heart rate, and renal sympathetic nerve activity; the responses were significantly enhanced in spontaneously hypertensive rats than in Wistar Kyoto rats. Co-injection of 2-nmol 2-methoxyidazoxan (a selective α2-adrenoceptor antagonist) or 2-nmol efaroxan (an I1-receptor antagonist) with 2 nmol of clonidine attenuated the hypotensive and bradycardic effects of clonidine-only injection. Injection of 2-methoxyidazoxan alone increased the blood pressure and heart rate in spontaneously hypertensive rats, but not in Wistar Kyoto rats. These results suggest enhanced responsiveness of α2-adrenoceptor/I1-imidazoline receptors in the rostral ventrolateral medulla of spontaneously hypertensive rats.

    Abstract Although the cardiovascular events such as stroke, angina pectoris and myocardial infarction can occur at any time of day, it has been known that the peak incidence of the cardiovascular events increases during the morning period. In elderly hypertensives, a greater morning blood pressure surge is associated with an advanced silent cerebrovascular disease as well as a higher incidence of stroke. Thus, the blood pressure control of the early morning period may become an important therapeutic strategy for preventing the cardiovascular events. In this review, we focused on the recent strategy for morning blood pressure rising in the elderly hypertensives.

    Abstract We report a case of IgA nephropathy with renal failure in which the deterioration of renal function was inhibited by the addition of angiotensin II receptor blocker (ARB) losartan. Before administration of losartan, the mean decline in the patient's glomerular filtration rate (GFR) was 0.64 ml/min/1.73 m2/month. Losartan treatment was started when serum creatinine rose above 4.0 mg/dl. With this treatment the serum creatinine level has remained stable for 3.5 years, and the mean decline in GFR was 0.06 ml/min/1.73 m2/month. We document successful retardation of renal failure with the use of losartan. Our experience suggests that dialysis therapy can be delayed significantly in patients using this drug.

    Abstract Blood pressure (BP) control throughout the entire day is recommended for cardiovascular protection. Angiotensin-II receptor blockers (ARBs) are widely used in hypertensive patients because of beneficial class effects. It is uncertain, however, whether are there any differences in 24-h BP profiles among ARBs. We examined ambulatory blood pressure monitoring (ABPM) among 211 Japanese hypertensive patients (age, 69.4 ± 9.6 years; female, 59.2%) under treatment with five different ARBs. Patients were divided into five groups according to ARBs prescribed. Patient backgrounds were almost identical in all the groups and there were no differences in office, 24-h and daytime BP; however, nighttime BP with olmesartan was significantly lower than with other ARBs. Office BPs with candesartan and telmisartan, but not other ARBs, correlated well with 24-h BP (p < 0.01). Also, there were higher correlations between daytime and nighttime BP with candesartan and telmisartan. In all patients, pulse pressure with office BP was significantly correlated with ambulatory arterial stiffness index (p = 0.001) and fluctuation of systolic BP on ABPM (p = 0.002). In conclusion, different ARB treatments produced meaningful differences in 24-h profiles.

    Abstract Background: The prevalence of chronic kidney disease (CKD) is high in developed countries, including Japan. However, little is known about the prevalence of anemia according to the estimated glomerular filtration rate (eGFR) among Japanese.
    Methods: We studied screenees on the Okinawa General Health Maintenance Association (OGHMA) registry in 1993 (N = 94,602; 54,848 women and 39,754 men) who had both serum creatinine and hematocrit data. Anemia was defined as follows: hematocrit level <40% in men, <32% in women aged <50 years, and <35% in women aged >or=50 years. GFR was estimated using a new Japanese equation: eGFR (ml/min per 1.73 m(2)) = 194 x serum creatinine(1.094) x age(0.287) x 0.739 (if female).
    Results: The prevalence of anemia clearly increased as CKD progressed below an eGFR of 60 ml/min per 1.73 m(2) in both genders. Logistic analysis adjusted with body mass index and older age (>or=70 years) revealed that the odds ratio for complications of anemia was significantly increased below an eGFR of 45 ml/min per 1.73 m(2) in women and 90 ml/min per 1.73 m(2) in men. The association of lower kidney function with anemia was found to be more prevalent: adjusted odds ratio >or=2.0, from approximately 50 ml/min per 1.73 m(2).
    Conclusion: The present study suggested that there might be as many as 1,000,000 people with CKD stage 3-5 complicated with anemia in Japan.

    Abstract Objective: Circulating endothelial progenitor cells (EPCs) play a critical role in maintaining the integrity of vascular vessels. The number of EPCs inversely correlates with the number of atherosclerotic risk factors. Although nonpharmacological treatment represents the first approach to the primary prevention of atherosclerotic diseases, little is known about the effects of diet on EPCs. We investigated the effect of a dietary intervention with vegetables that are commonly eaten in Okinawa on the number of EPCs.
    Methods and results: Forty-five healthy young women were employed and randomized to a dietary intervention group (n=24) or a control group (n=21). Subjects in the intervention group received typical Okinawan vegetables through home-parcel delivery for 2 weeks. After the dietary intervention, urinary potassium and magnesium excretion increased only in the intervention group and changes were greater than in the control group (p=0.007, 0.010, respectively). The consumption of total vegetables correlated with changes in both urinary potassium and magnesium excretion. Serum folic acid increased and plasma homocysteine decreased in both groups but the change was significant only in the intervention group. The EPCs number significantly increased in the intervention group but did not in the control group. An inverse correlation was observed between EPC number and plasma homocysteine level (r=-0.272, p=0.016). Changes in the EPC number inversely correlated with changes in both serum total cholesterol and low-density lipoprotein cholesterol level (r=-0.555, p=0.0002; r=-0.626, p<0.0001, respectively).
    Conclusions: The consumption of vegetables increased the number of circulating EPCs; this change might be associated with a homocysteine-lowering effect.

    Abstract Objectives: Thiazide diuretics are one of the first choice antihypertensives but not optimally utilised because of concerns regarding their adverse effects on glucose metabolism. The Diuretics In the Management of Essential hypertension (DIME) study was designed, for the first time, to assess the risk for type 2 diabetes mellitus in patients with essential hypertension during antihypertensive treatment with low-dose thiazide diuretics compared to those not treated with diuretics.
    Design: Multicentre, unblinded, pragmatic, randomised, controlled trial with blinded assessment of end points and intention-to-treat analysis that was started in 2004 and finished in 2012.
    Setting: Hypertension clinics at 106 sites in Japan, including general practitioners' offices and teaching hospitals.
    Participants: Non-diabetic patients with essential hypertension.
    Interventions: Antihypertensive treatment with low-dose thiazide diuretics at 12.5 mg/day of hydrochlorothiazide or equivalent (Diuretics group) or that without thiazide diuretics (No-diuretics group).
    Main outcome: The primary outcome was new onset of type 2 diabetes diagnosed according to WHO criteria and the criteria of Japanese Society of Diabetes.
    Results: 1130 patients were allocated to Diuretics (n=544) or No-diuretics group (n=586). Complete end point information was collected for 1049 participants after a median follow-up of 4.4 years. Diabetes developed in 25 (4.6%) participants in the Diuretics group, as compared with 29 (4.9%) in the No-diuretics group (HR 0.93; 95% CI 0.55 to 1.58; p=0.800).
    Conclusions: Antihypertensive treatment with thiazide diuretics at low doses may not be associated with an increased risk for new onset of type 2 diabetes. This result might suggest safety of use of low doses of thiazide diuretics.
