Serum peptide III-procollagen and ACE in asbestos workers. 1991

H Owczarek, and E Lewczuk

Department of Medical Analytics, Medical Academy Wroclaw, Poland.

Type-III-procollagen peptide (P-III-P) concentration and angiotensin-converting-enzyme (ACE) activity were measured in the serum of asbestos workers. The subjects were classified into four groups (A, B, C, D) according to the duration of exposure (in years). A gradual increase of ACE activity in group B and P-III-P concentration in group C was found. The increase in ACE activity can be regarded as the response to the progressing inflammatory state, and the increase in P-III-P concentration may be related to the fibrosis of the lung tissue.

UI	MeSH Term	Description	Entries
D007703	Peptidyl-Dipeptidase A	A peptidyl-dipeptidase that catalyzes the release of a C-terminal dipeptide, oligopeptide-\|-Xaa-Yaa, when Xaa is not Pro, and Yaa is neither Asp nor Glu. Thus, conversion of ANGIOTENSIN I to ANGIOTENSIN II, with increase in vasoconstrictor activity, but no action on angiotensin II. It is also able to inactivate BRADYKININ, a potent vasodilator; and has a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety.

D011348	Procollagen N-Endopeptidase	An extracellular endopeptidase which excises a block of peptides at the amino terminal, nonhelical region of the procollagen molecule with the formation of collagen. Absence or deficiency of the enzyme causes accumulation of procollagen which results in the inherited connective tissue disorder--dermatosparaxis. EC 3.4.24.14.

D011658	Pulmonary Fibrosis	A process in which normal lung tissues are progressively replaced by FIBROBLASTS and COLLAGEN causing an irreversible loss of the ability to transfer oxygen into the bloodstream via PULMONARY ALVEOLI. Patients show progressive DYSPNEA finally resulting in death.

D001194	Asbestos	Asbestos. Fibrous incombustible mineral composed of magnesium and calcium silicates with or without other elements. It is relatively inert chemically and used in thermal insulation and fireproofing. Inhalation of dust causes asbestosis and later lung and gastrointestinal neoplasms.
D001195	Asbestosis	A form of pneumoconiosis caused by inhalation of asbestos fibers which elicit potent inflammatory responses in the parenchyma of the lung. The disease is characterized by interstitial fibrosis of the lung, varying from scattered sites to extensive scarring of the alveolar interstitium.
