Plasma pharmacological study on Da huang zhe chong capsule on platelet aggregation of normal person

Abstract

Objective To develop a plasma pharmacological method evaluates the effect of Da Huang Zhe Chong capsule on platelet aggregation and its mechanism, which is a representative Traditional Chinese Medicine Patent Prescription Promoting blood circulation by removing blood stasis. Methods Platelets specimens from healthy volunteers made serum and plasma with medicine, while platelet PRP were separated, which were divided into 8groups, i. e. auto-serum, allo-serum, serum with Da Huang Zhe Chong capsule, serum with aspirin, auto-plasma, plasma with Da Huang Zhe Chong capsule, plasma with aspirin, every group added to serum and plasma to hatch. After ADP and adrenalin were added into the specimens and hatched, the effects of specimens on platelet aggregation were observed. Results After ADP adrenalin were added, all the serum groups did not present platelet aggregation, while all the plasma group presented platelet aggregation. P ₁, P ₅, P _max, t and T _M have no significant difference (P>0.05) between auto-plasma group and allo-plasma group induced by ADP and adrenalin, P ₁, P ₅, t and P _max have significant differences (P<0.01) and T _M decreased significantly (P<0.05) comparing plasma group with Da Huang Zhe Chong capsule and plasma group of aspirin to allo-plasma group. P ₁, t and P _max have significant difference (P<0.05), and P ₅ and T _M are simulate comparing plasma group with Da Huang Zhe Chong capsule to plasma group of aspirin. P ₁, P ₅, t and P _max have significant differences (P<0.01), P ₁, T _M have also significant (P<0.05), comparing plasma group of Da Huang Zhe Chong capsule with plasma of aspirin to allo-plasma group induced by adrenalin. P ₁, P ₅ and P _max have significant differences (P<0.05), and t and P _max are simulate comparing plasma group with Da Huang Zhe Chong capsule with plasma group of aspirin. Conclusion The serum pharmacological study is inappropriate to study platelet aggregation in vitro. The plasma pharmacological study is inappropriate to study platelet aggregation in vitro. The plasma pharmacological study could reflect the pharmacological effect produced in vivo. Da Huang Zhe Chong capsule has better anti artery thrombosis effect than aspirin, and it is an ideal medicine for anti artery thrombosis.
