Effect of Scolopendrid Calculus Bovis-Fel Uris- Moschus Bee Venom and Sweet Bee Venom on Regional Cerebral Blood Flow after Pharmacopuncture to GV16 Pungbu and GB20 Pungji in Rat

This study was designed to investigate the effect of four pharmacopuncture drugs (scolopendrid, Calculus Bovis-Fel Uris-Moschus (BUM), bee venom 25%, and sweet bee venom 10%) on the cerebral hemodynamics, including changes in the regional cerebral blood flow (rCBF) and in the mean arterial blood pressure (MABP). The changes in the rCBF and the MABP were determined by using a laser-Doppler flowmeter and a pressure transducer, respectively. Scolopendrid (0.3 ml, 1 ml/kg) caused no significant changes in the rCBF and the MABP, whereas BUM (0.3 ml, 1 ml/kg) decreased the rCBF and the MABP, bee venom 25% (0.3 ml, 1 ml/kg) increased the rCBF and lowered the MABP, and sweet bee venom 10% (0.3 ml, 1 ml/kg) increased the rCBF and had no significant effect on the MABP. The rCBF and the MABP were influenced differently by the administration of various pharmacopunctures. Further studies are needed to elucidate the underlying mechanism.
