Effects of late-onset and long-term captopril and nifedipine treatment in aged spontaneously hypertensive rats: Echocardiographic studies.

The purpose of the present study was to analyze the changes in blood pressure, left ventricular (LV) wall thickness and LV systolic function of aged spontaneously hypertensive rats (SHRs) either with or without antihypertensive therapy. Twenty-one SHRs aged 60.5±0.

Ribose treatment reduced the infarct size and improved heart function after myocardial infarction in rats.

Objective: In this study the effect of ribose on heart function and infarct-size was analyzed 6 h after myocardial infarction (MI) in rats.

Methods: Continuous i.v.

[The significance of perioperative immunonutrition].

Perioperative immunonutrition is aiming at modulating altered immunological and metabolic functions in the context of major surgery. It is defined as the supplementation of constitutionally essential substrates such as glutamine, arginine, omega-3-fatty acids or nucleotides. The application of such formula is recommended for patients undergoing major abdominal-surgical procedures and tumour surgery in the head neck area.

Cord blood cell therapy alters LV remodeling and cytokine expression but does not improve heart function after myocardial infarction in rats.

Objective: In this study the ability of unrestricted somatic stem cells (USSC) and mononuclear cord blood cells (MN-CBC) was tested to improve heart function and left ventricular (LV) remodeling after myocardial infarction (MI).

Methods: The cells were delivered by i.v.

Tissue inhibitor of matrix metalloproteinase-1 in norepinephrine-induced remodeling of the mouse heart.

Background: Matrix metalloproteinases (MMPs) play an important role in myocardial remodeling. Their activity is regulated by the tissue inhibitors of metalloproteinases (TIMPs). The present study analyzed the contribution of changes in functional and molecular parameters to early cardiac remodeling in mice hearts.

Contrast enhanced echocardiographic follow-up of cardiac remodeling and function after myocardial infarction in rats.

Echocardiography is a reliable and commonly used method to examine cardiac diseases. Recent employment of modern technologies provides new opportunities to study left ventricular (LV) remodeling after myocardial infarction (MI) also in small rodents. LV volumes as most important prognostic parameters can be estimated by noncontrast enhanced echocardiography in rats from M-mode or single cross sections only.
