Very few studies have been carried out on the role of liver macrophages (Kupffer cells) during the course of hepatic amoebiasis. The kinetics of phagocytic activity of Kupffer cells and blood monocytes was studied in guinea pigs intra-mesenterically infested with Entamoeba histolytica. The phagocytic capacity of blood monocytes of normal animals was comparatively lower than Kupffer cells for both latex and haemolysin coated sheep red blood cells. Significant decline in phagocytic response of Kupffer cells and blood monocytes of infected animals was observed right from 2nd post infection day and it kept on decreasing with the progress of infection. Depression in phagocytic response of Kupffer cells and blood monocytes was more marked in those animals who had higher grades of pathological lesions. Hence, an inverse correlation was obtained between the phagocytic capacity and severity of amoebic lesions (P less than 0.01). The significance of depression in phagocytic response of Kupffer cells and blood monocytes may be responsible for the development of hepatic lesions.
