OBJECTIVE Asia is predicted to have the largest population of patients with diabetes who are at high risk for renal disease. In the Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan (RENAAL) study, approximately 17% of patients were Asians. In this subgroup analysis, we examined the characteristics, response, and adherence to treatment of the Asian population, as well ...

BACKGROUND Muscle contusions are a common type of muscle injury and are frequently encountered in athletes and military personnel. Although these injuries are capable of healing in most instances, incomplete functional recovery often occurs because of the development of fibrosis in the muscle. We hypothesized that a combination of platelet-rich plasma (PRP) injection and oral administration of ...

BACKGROUND The aim of this study was to compare the antihypertensive efficacy of losartan 100 mg + hydrochlorothiazide (HCTZ) 25 mg versus bisoprolol 10 mg + HCTZ 25 mg and their influence on arterial stiffness and central blood pressure (BP). METHODS Of 60 patients with a mean BP of 173.3 ± 1.7/98.4 ± 1.2 mmHg, 59 were randomized to losartan + HCTZ (n = 32) or bisoprolol + HCTZ (n = 27). Aml...

In 12 conscious dogs, we investigated whether the angiotensin II-receptor antagonist losartan increases renal sodium excretion and urine volume during controlled mechanical ventilation (CMV) with positive end-expiratory pressure. In four experimental protocols, the dogs were extracellular volume (ECV) expanded (electrolyte solution, 0.5 ml ⋅ kg-1 ⋅ min-1iv) or not and received losartan (100 μg ...

The aim of this study was to determine whether losartan, an angiotensin II (Ang II) type 1 (AT(1)) receptor could influence the CA release from the isolated perfused model of the rat adrenal medulla. Losartan (5~50 microM) perfused into an adrenal vein for 90 min produced dose- and time-dependent inhibition of the CA secretory responses evoked by ACh (5.32 mM), high K(+) (56 mM, a direct membra...

The present study aimed to investigate the impact of losartan and angiotensin II (AngII) on the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1), secreted by rat vascular smooth muscle cells (VSMCs). Rat VSMCs were isolated and cultured in different concentrations of AngII and losartan for 24 h and western blot analysis and quantitative polym...

BACKGROUND The most suitable antihypertensive drug to reduce the risk of cardiovascular disease in patients with hypertension and diabetes is unclear. In prespecified analyses, we compared the effects of losartan and atenolol on cardiovascular morbidity and mortality in diabetic patients. METHODS As part of the LIFE study, in a double-masked, randomised, parallel-group trial, we assigned a gr...

Abstract Background and Aims Tertiary lymphoid tissues (TLTs) have been demonstrated as a major cause of sustained inflammation after acute kidney injury (AKI), indicating possible contribution ensuing chronic disease (CKD). And heterogeneous fibroblasts play the crucial role induction TLT by secretion chemokines. Angiotensin II receptors also express on including pericytes. Our study aimed to ...

Background: The purpose of this study was to investigate whether brain AT1 receptor stimulation contributes as a hypertensive mechanism to deoxycorticosterone acetate (DOCA)-salt hypertension. Methods: 1) Acute injection: Losartan (1 mg/4 uL) or artificial cerebrospinal fluid (aCSF) was injected into the lateral cerebral ventricle (icv) of conscious control uninephrectomized Wistar rats or rats...

Humans genetically predisposed to hypertension tend to develop at a prehypertensive stage subtle metabolic and hormonal dysregulations, and certain of these could potentially be angiotensin II dependent. Therefore the aim of this study was to investigate the effects of the angiotensin II-receptor antagonist losartan on insulin sensitivity, lipid profile, and plasma endothelin-1 (ET-1) levels in...
