In addition the urine porphyrins and porphyrin precursor excretions were measured. It was found that in sideropenic patients the erythrocyte \u03b4-ALA dehydratase activity was almost constantly higher than in normals; the difference of the mean values being statistically significant (p &lt; 0.005). A significant diminution of \u03b4-ALA (p &lt; 0.0025) urine excretion was observed, whereas the urine excretion of PBG, CP and UP was found within the normal limits. The results are compared to those reported by other authors.<\/jats:p>","DOI":"10.1159\/000207895","type":"journal-article","created":{"date-parts":[[2009,3,4]],"date-time":"2009-03-04T06:05:48Z","timestamp":1236146748000},"page":"305-309","source":"Crossref","is-referenced-by-count":8,"title":["Erythrocyte \u03b4-Aminolaevulinic Acid Dehydratase, Urinary Porphyrins and Porphyrin Precursors in Iron Deficiency Anaemia"],"prefix":"10.1159","author":[{"given":"G.","family":"Chalevelakis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Lyberatos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Manopoulos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Pyrovolakis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Gardikas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,3,3]]},"container-title":["Acta Haematologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/207895","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000207895","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T12:40:07Z","timestamp":1777466407000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000207895"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,3,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000207895","archive":["Portico"],"relation":{},"ISSN":["0001-5792","1421-9662"],"issn-type":[{"value":"0001-5792","type":"print"},{"value":"1421-9662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,3,3]]}}}
