Asymmetric Pattern of Correlations of Leucine Aminopeptidase Activity between Left or Right Frontal Cortex versus Diverse Left or Right Regions of Rat Brains

Previous studies demonstrated an asymmetry of left predominance for mean values soluble leucine aminopeptidase (LeuAP) activity in the frontal cortex (FC) and hypothalamus adult male rats, fluorimetrically analyzed by hydrolysis Leu-β-naphthylamide as a substrate. No asymmetries were observed nine other (L) right (R) regions obtained from rostro-caudally sectioned coronal slices. Neither had inter-hemispheric differences lactate dehydrogenase (LDH), simultaneously same brain (L R) animals. However, level intra-hemispheric or correlation LeuAP LDH between such has not been analyzed. In order to obtain additional suggestions on functional heterogeneity LDH, present investigation, correlations with rest studied is described: (A) (LFC) regions; (B) (RFC) (C) all (D) regions. All positive. The analysis showed greater RFC than LFC Greater when comparing conclusion, greatest (suggesting variability) was hemisphere. results great homogeneity both intra- studies.
