Table 1. Measurment of brain cortical water content of hypoglycemic rats.

Group	Number of rats	Water content (%)
Normal Control	5	80.24±0.40
Sham Hypo	5	79.93±0.41
Hypo	7	81.28±0.75#
Sham Hypo + R 24 h	5	79.82±0.35
Hypo + R 24 h	5	81.62±1.08##
Hypo + R 3 d	5	79.90±0.51

Hypoglycemia resulted in an increase of brain water content. # p<0.01 compared to Normal Control and Sham Hypo Group. ## p<0.01, compared to Normal Control, Sham Hypo, Sham Hypo + R 24 h (Holm-Sidak method).

Hypo: hypoglycemia, Sham Hypo: sham hypoglycemia. Hypo + R: hypoglycemia + recovery. Data are shown as mean ± SD.
