Abstract
PONCE DE LEON, Patricia and LOPEZ MURUA, Gabriel. Alteration of erythrocyte sialic acid by the effect of Trichinella spiralis applying the Alcian Blue method. Acta bioquím. clín. latinoam. [online]. 2018, vol.52, n.4, pp.411-416. ISSN 0325-2957.
It is now recognized that sialic acids are involved in multiple biological functions and that they have an important role in the parasite-host interaction. The objective of this work was to study the alteration of erythrocyte sialic acid by the effect of T. spiralis applying the Alcian Blue method. Work was carried out with 11 larval concentrates of ML and 9 of NL (total 20) and with fresh erythrocyte suspensions. The treatment was performed incubating the globular sediment with equal volume of larval concentrate (37 °C for 1 hour). The controls were incubated in the same way with saline solution. The Alcian Blue method was applied and CAE% was determined in the control and in the treated globules. CexpCAE was calculated. The results showed that 5/9 of the NL concentrates and 9/11 of ML modified the globular charge. The mean and standard deviation of the CexpCAE of the suspensions in which the charge decreased by contact with NL and ML were 0.614±0.1946 and 0.656±0.1865 respectively, whereas in those that did not change, it was 0.955±0.0289 in the NL treatment and 0.93±0.0141 in the ML. It is concluded that the Alcian Blue Method is useful to study the variations in erythrocyte charge due to NL and ML of T. spiralis.
