The effect of lithium on blood glucose and insulin levels.

12-week old female BTBR-WT and -ob/ob mice received standard chow or chow with lithium supplementation (10 or 40 mmol LiCl/kg) for 12 weeks. Two weeks before sacrifice, mice were fasted for 4 hours, after which they received an intraperitoneal injection of 2 mg glucose/g bodyweight. Blood was collected before and 15 minutes after injection and blood glucose levels were determined (A). At the time of sacrifice blood was collected to analyze non-fasting (B) glucose and (C) insulin levels, n = 9 per group. *p<0.05; **p<0.01; ***p<0.001.
