Interference of pulse short waves on macrophage adhesion and phagocytosis in rats with neonatal malnutrition

Abstract

In view of the established relationships between neonatal malnutrition and the immuno system, peritoneal macrophages of male Wistar rats were exposed to diatermic pulsate short waves (DPSW) and to alternated magnetic field on extreme low frequency, in order to verify in vitro adhesion index and phagocytic activity. The rats were submitted to malnutrition during the nursing period and to a recovery diet after weaning. The extracted peritoneal macrophages were exposed to DPSW
modulated at 30 Hz, 50 Hz and 430 Hz by using the Schliephake and
conventional techniques in parallel, and to a magnetic filed of 60 Hz. Results show increased adhesion index only with the 30 Hz and 50 Hz
experimental groups using Schliephake technique and C M 60 Hz; phagocytic activity was reduced with 30 Hz and 50 Hz using Schliephake
technique and C M 60 Hz, as compared to the control group (p<0,05).
Since macrophages of malnourished and recovered animals responded to such irradiations, and since these are largely used in physical therapy, present results could be used to choose correct DPSW modulation in therapeutic process, particularly in cases who have previously suffered malnutrition.
