Serum angiotensin converting enzyme activity in human bronchial asthma.

Serum angiotensin converting enzyme activity in human bronchial asthma.

Using hippuryl-L-histidyl-L-leucine as a substrate analog, serum angiotensin converting enzyme (ACE) was spectrophotometrically estimated in patients with bronchial asthma. There were significantly low activities of serum ACE in 115 patients with bronchial asthma irrespective of the presence or absence of acute attack. The activity of serum ACE was reduced more markedly in the chronic type of b...

Serum Angiotensin Converting Enzyme in Patients with Psoriasis

Background: Controversial data concerning the elevation of serum angiotensin-converting enzyme in psoriasis are reported in the literature. In order to verify whether this abnormality exists in Iranian patients, we performed this study. Method: Serum angiotensin-converting enzyme level was measured in 40 psoriatics. According to clinical forms of psoriasis, patients were further divided into th...

Angiotensin-converting enzyme activity in ovine bronchial vasculature.

Angiotensin-converting enzyme (ACE) plays a major role in the metabolism of bradykinin, angiotensin, and neuropeptides, which are all implicated in inflammatory airway diseases. The activity of ACE, which is localized on the luminal surface of endothelial cells (EC), has been well documented in pulmonary EC; however, few data exist regarding the relative activity of ACE in the airway vasculatur...

silica exposure and serum angiotensin converting enzyme activity

background: silicosis is known in industrial workers for centuries. till recently, the mainstay of its diagnosis and progress was clinical examination of the respiratory system, pulmonary function test and chest radiography. several biomarkers such as serum angiotensin converting enzyme (ace) activity have been examined to determine the extent of silicosis. objective: to elucidate the effect of...
