Table 1 Body and organ weights and morphometrical measurements in fed and 72 h fasted mice

From: Fasting induces a biphasic adaptive metabolic response in murine small intestine

  fed 72 h fasting
body weight (g) 27.8 ± 0.9 18.9 ± 0.5*
intestinal wet weight (g) 1.2 ± 0.1 0.6 ± 0.1*
villus height (μm) 368 ± 63 353 ± 54
CPS-positive volume fraction (%) 72.2 ± 3.4 71.0 ± 0.5
αSMA-positive volume fraction (%) 24.6 ± 1.1 24.0 ± 3.0
PCNA volume fraction (%) 18.8 ± 1.4 20.6 ± 1.0
Alcian blue-positive cells^ 68.7 ± 6.3 69.0 ± 11.1
caspase 3-positive cells^ 56.0 ± 7.2 91.8 ± 14.9*
total protein content of the intestine# (mg/g) 20.9 ± 2.2 16.8 ± 2.0*
  1. Data are shown as average ± SEM. There are no significant differences between the experimental groups with regard to villus height, CPS-, αSMA- and PCNA-positive volume fraction, and number of Alcian-blue positive cells. Body and organ weight, caspase 3-positive cells, and total protein content differed significantly (*, P < 0.01). ^: for caspase 3- and Alcian blue-positive cells, the numbers are given per mm2. #: total protein content of the gut was available for fed and 48 h-fasted animals only.
