Table 5. Effects of the aqueous leaf extract of P. suberosa on gastrointestinal and diaphragm glucose uptake and liver and skeletal muscle glycogen content in mice.

The data are presented as the means ± SEM (n = 9). The control group was given distilled water, and the test group was given 50 mg/kg of the extract. To measure the diaphragm glucose uptake and glycogen content in the liver and skeletal muscles, the mice were treated for 30 days. For the measurement of intestinal glucose absorption, the mice were treated with acute doses.

Parameters	Control	Treatment
Gastrointestinal absorption of glucose (mg/dL)	17.59 ± 1.54	84.5 ± 2..65**
Diaphragm uptake of glucose (mg/dL)	33.51 ± 0.28	32.83 ± 0.43
Glycogen content in the liver (mg/dL)	1.421 ±  0.06	3.822 ± 0.14**
Glycogen content in skeletal muscle (mg/dL)	3.018 ±  0.04	6.868 ±  0.16**
