Serum protein electrophoresis is a simple, reliable, and specific method used for separation of serum proteins. This study consisted to detect, at pediatric cases, pathological profiles of serum proteins by capillary electrophoresis and interpret any anomalies. The study was performed on 81 sera collected from pediatric subjects admitted at the Abderrahim Harouchi Children’s Hospital in Casablanca. Study results revealed 72 specific pathological electrophoretic patterns for acute and chronic inflammatory response (35 children), hypogammaglobulinemia (3), polyclonal hypergammaglobulinemia (23), hypoalbuminemia (5), agammaglobulinemia (1), and other medical conditions (2). No cases of alpha-1-antitrypsin deficiency and nephrotic syndrome by electrophoresis were highlighted. Serum protein electrophoresis in children is recommended as a diagnostic technique for increasing the accuracy of the diagnosis in acute, subacute, and chronic inflammatory diseases, liver disease, and cases of immunodeficiency.

Chemical pollution in the peri-urban area of Casablanca impacts the quality of agricultural soils.Five sites from the region of Casablanca have been studied: Oued Hassar, Oued Merzeg, Bouskoura, Benslimane-Mohammedia, and Bouznika.The objective is the comparative analysis of five trace metal elements in soils in order to assess the environmental state and to preserve the potential and harmlessness of sites in the Casablanca region.The environmental state of these sites requires knowledge of the physico-chemical parameters of the soil (PH, Calcium carbonates, organic matter), following the degradation of irrigation water by the use of wastewater or the impact of chemical pollution.The environmental state studied through metallic trace elements shows that the soils of sites irrigated by Oued Hassar have cadmium and lead contents which exceed the standards recommended by the World health organisation (WHO), respectively 2 ppm and 100 ppm.The contents are respectively 2,91 ppm and 137,61ppm.The copper contents in the soils irrigated by the Merzeg wadi remain the highest.The contents are 896,62 ppm. The zinc contents in soils near the Bouskoura cement plant are predominant compared to the other elements.The contents are 537,22 ppm. In Mohammedia-Benslimane soils, the cadmium contents are very variable, moderate and can exceed 2 ppm. Lead levels rarely exceed 100 ppm.The statistical study by the Anova test shows significant differences in the contents of metallic trace elements except for nickel.
