Recent trends in hypertension treatment: perspectives from animal studies Introduction

Several newer areas of hypertension research are presented in this supplement. First, the benefits of melatonin in the treatment of experimental hypertension including its cardioprotective effects are introduced. Second, the possible role of melatonin in the non-dipping blood pressure pattern is described. Third, two hypotheses discuss the potential reasons for the ineffectivness of antioxidants in hypertension treatment, and difficulties associated with interpretations of experimental findings in the model of the spontaneously hypertensive rat (SHR). Finally, interactions of indapamide with the nitric oxide system in SHR, the protective effect of angiotensin II type 1 receptor blockade against alterations in insulin-resistant rats, and the deleterious effect of a low protein diet on kidney maturation with the development of hypertension are presented.
