Abstract
The present study, deals with the hydrogeochemical distribution of some trace elements in drinking water with determination of iron levels in patients who suffering from liver diseases in Mansoura environs. Also, estimation the levels of liver and spleen overloaded with iron in albino rats and the treatment of iron overload diseases with natural chelating agent (Catechin). Laboratory studies were carriedout to achieve the aim of the present work. The physical, chemical and microbiological analyses of (144) water samples represent the different types of drinking water (surface, wells and tap) in the governorate. The serum iron levels in (140) selected inhabitants who attended in the Emergency hospital, Mansoura University, from different localities and suffering from liver diseases have been determined as one of the main causes of liver fibrosis. Moreover, 30 albino rats were subjected to analysis for iron biochemical and histopathologically. A high similarity is found between the present and previous analyses, indicating that the types of surface and groundwater have not changed much along these years (2001 to 2004). This is attributed to the fresh main sources of recharge.The comparison between iron concentration in drinking water and blood samples show a great compatibility. The present ironchelating agent (Catechin) led to decrease of iron levels in liver and spleen of treated animals. This agent may form a complex with excess iron in both of these organs, which could treat the ironoverload.
