(a–d) Representative photomicrographs of astrocytes in the third level of the paraventricular nucleus (PVN) of targeted Gαi₂ or control scrambled (SCR) intracerebroventricular oligodeoxynucleotide (ODN)‐infused [25 µg (5 µl)⁻¹ day⁻¹ for 7 days] male Sprague–Dawley rats on 7 days of normal‐salt (NS; 0.6% NaCl) or high‐salt (HS; 4% NaCl) diet. (a) SCR ODN‐infused rat on NS diet. (b) SCR ODN‐infused rat on HS diet. (c) Gαi₂ ODN‐infused rat on NS diet. (d) Gαi₂ ODN‐infused rat on HS diet. (e) Percentage tissue composition of astrocytes in the PVN of Sprague–Dawley rats during SCR or Gαi₂ ODN infusion maintained on NS or HS diet. Abbreviation: 3V, third ventricle. (n = 5 per group, scale bar: 200 µm; ×20 magnification; mean ± SD.)
