Figure 7. The volume of the striatal region is reduced by 3-NP injection.
To confirm that the 3-NP treatment was effective, we examined the striatum and SCN of a cohort of treated mice. Using Nissl and hematoxylin and eosin staining, we found that the striatum exhibited pathological damage in all of the treated mice (n=10/10). To provide one measure, the ventricle volumes adjacent to the striatum as well as the SCN were measured. Top left: photomicrographs (4×) of striatum Nissl staining sections. Top right: averaged ventricle size of striatum. *P<0.05, Student's t test (vs control). Bottom left: photomicrographs (10×) of SCN Nissl staining sections. 3V, 3rd ventricle, OC, optic chiasm. Bottom right: averaged SCN size. Data are shown at means+S.E.M.
