Fig. 5. The expression of glutamic acid decarboxylase (GAD) protein in the rat hypothalamus after 1, 5, and 9 d of red ginseng extract (RGE) treatment. Hypothalamus membrane extracts from rats treated as controls or with RGE were analyzed by Western blotting. A representative image is shown in each case. The intensity of the immunoreactive bands of 3 to 4 independent experiments was measured by densitometry scanning and normalized using glyceraldehyde 3-phosphate dehydrogenase (GADPH) as a standard (bar graph). The results are presented as the percentage immunoreactivity detected in the hypothalamus with respect to the GADPH proteinloading control. Values are expressed as the mean±SEM. **p<0.01 compared with the control.
