Values are means ± S.D. number of images analyzed in each group:8; A, Total area of air space; P, Total perimeter (contour length) of air space; P/A, perimeter per unit area; S/V (surface density) = π/4 × P/A. The groups represent: Air, air exposed; CS, exposed to CS; BT, air exposed guinea pigs given BT as the drink; CS+BT, CS-exposed guinea pigs given BT as the drink. * Arbitrary unit using NIH image | |||||
