[Mature-type adrenomedullin in coronary circulation immediately after reperfusion in patients with anterior acute myocardial infarction].

Objective: Levels of adrenomedullin (AM), a potent vasodilatory peptide, have been shown to increase in the early stage of acute myocardial infarction (AMI). The purpose of this study was to determine whether coronary sinus-aortic step-up of mature forms of AM is accelerated in patients with AMI after reperfusion.

Methods: The subjects were 146 consecutive patients with a first episode of anterior AMI and 51 normal controls.

[Polymorphic Hind III restriction site of the Y chromosome and essential hypertension in Chinese Han People].

Objective: To examine whether there is an association essential hypertension pressure and a polymorphic Hind III biallelic marker in the non-recombining region of Y chromosome in Chinese Han people.

Methods: Peripheral blood samples were collected from 402 males with essential hypertension pressure and 455 age- and body height-matched healthy males as control group. Genomic DNA was extracted from the white blood cells.
