Method Pharmacokinetics
Cell Lines C57BL/6J-Bom mice
Concentrations 0.01, 0.1, 1, 10, or 50 mg/kg
Incubation Time 90 min
Results Mice administered a higher 50-mg/kg (1)-naloxone dose in combination with heroin demonstrated a clear reduction in locomotor activity (41% reduction in maximal distance run), as did mice given this dose of (1)-naloxone in combination with 6-AM

Method Locomotor Activity
Cell Lines C57BL/6J-Bom mice
Concentrations 0.01, 0.1, or 1 mg/kg
Incubation Time 60 min
Results Thereafter, locomotor activity increased until approximately 90 minutes after morphine administration, displaying an almost 40% reduction of the maximal distance run (P,0.01), before it declined. The lowest dose of (2)-naloxone showed no effect on morphine-induced locomotor activity
Cell Experiment
Cell lines BV‐2 cells
Preparation method The phagocytic activity of BV‐2 cells was measured by Vybrant phagocytosis assay kit according to the manufacturer's instructions. Briefly, BV‐2 cells were treated with LPS (200 ng·mL−1) and (+)‐naltrexone/(+)‐naloxone for 24 h.
Concentrations 20 μM
Incubation time 24 h
Animal Experiment
Animal models adult male C57BL/6J-Bom mice
Formulation saline
Dosages 0.01, 0.1, or 1 mg/kg

Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
