Piromelatine (20 mg/kg, ip, daily) treatment prevents insulin resistance induced by sleep restriction.
Piromelatine (5-50 mg/kg, ip, daily) decreases plasma glucose significantly.
Piromelatine (100 mg/kg) decreases thermal hyperalgesia and mechanical allodynia in PSL (partial sciatic nerve ligation) mice.
西域 has not independently confirmed the accuracy of these methods. They are for reference only.
| Animal Model: |
Twenty four male Sprague-Dawley rats (3 months old, weighing 250-300 g). |
| Dosage: |
20 mg/kg. |
| Administration: |
IP, daily at 8:00 p.m. |
| Result: |
Resulted in significantly decreased plasma glucose levels (6.670.35 mmol/L, 6.770.34 mmol/L vs. 8.27 0.38 mmol/L), and the plasma glucose levels of the two groups were even neared to that of the normal control group (6.07±0.35 mmol/L).
Resulted in a decrease in triglycerides and total cholesterol levels (51.8% and
43.0%, respectively) and an elevation in HDL-C level (increase of 32.4%).
|
| Animal Model: |
Five groups of 12-wk-old rats (10/group). |
| Dosage: |
5-50 mg/kg. |
| Administration: |
Intraperitoneal injection in 18:00 every day. |
| Result: |
Plasma glucose was decreased significantly by 27.3%, 34.5% and 61.5%, respectively. |
| Animal Model: |
Male C57BL/6 J mice, weighing 22-26 g (10 weeks old; PSL mice). |
| Dosage: |
25, 50, or 100 mg/kg. |
| Administration: |
IP 1 h before assessment of thermal hyperalgesia and mechanical allodynia. |
| Result: |
Remarkably prolonged thermal latency (surgery×treatment interaction, F1,24=15.7, p<0.001; surgery×treatment×hours interaction, F5,120=3.0, p<0.05) and increased mechanical threshold (surgery×treatment interaction, F1,24=18.4, p<0.001; surgery× treatment×hours interaction, F5,120=2.6, p<0.05) for 4 h after administration of piromelatine to PSL mice. |
