The invention provides a non-
diagnostic evaluation method for a mouse back
psoriasis model after construction, which comprises the following steps: S1, determining the percentage of a
mouse skin lesion area in a
drug application area
skin lesion area, and scoring by 0-2 scores according to a
skin lesion area proportion B, 0% = 0
score, 1%-30% = 1
score, and 31%-100% = 2
score; s2, determining an
erythema score E, wherein the E is divided into 0-2 scores according to the
color depth of the
erythema; s3, a scale score D is determined, scoring is carried out according to the scale covering
skin damage area, the scale covering with no scale is equal to 0 score, the scale covering with 30% of
skin damage is equal to 1 score, the scale covering with 60% of
skin damage is equal to 2 score, and the scale covering with 90% or above of
skin damage is equal to 3 score; s4, determining a plaque score I, performing scoring by 0-3 scores according to the size of the plaque, and if no is equal to 0 score, determining the
average diameter of the plaque as lt; 2 mm is equal to 1 minute, the
average diameter of the plaque is 2-4 mm and is equal to 2 minutes, and the
average diameter of the plaque is gt; 4 mm is equal to 3 minutes; s5, the
skin lesion severity S is determined, S = B + E + D + I, the mouse back skin
psoriasis inflammation severity is more accurately described and quantitatively compared according to the S score, and intuitive and accurate
statistical analysis is facilitated.
