RESUMO
Objective To study the anti-inflammation mechanism of Jinzhuyalong Ershiwuwei coral capsule on cervical spondylosis by investigating Jinzhuyalong Ershiwuwei coral capsule on PLA2 in degenerated cervical intervertebral discs.Methods 60SD rats (SPF) were divided into a control group (15),a medicine model control group (15),a medicine modle 1 group (15),and a medicine model 2 group (15) by random lottery; Medicine model 1,2 groups were given Jinzhuyalong Ershiwuwei coral capsule powder 0.33 × 5 g/kg 0.66×5 g/kg,and added 1 ml distilled water dilution lavage,l/d,90 d,The unbalance of power cervical spondylosis animal models were chosen and C4～5 neck intervertebral discs were taken after 90 days.Millipore colorimetry methods were used to measure PLA2 activity in C4～5 cervical intervertebral discs.Results The PLA2 activity of the cervical intervertebral disc (12.37 ± 4.21) IU/mg · min-1 in the model group was significantly higher than the control group(2.56± 1.19)IU/mg· min-1 (P＜0.05).The cervical intervertebral disc PLA2 activity of medicine model group 1 (8.56± 2.13)IU/mg · min-1 and medicine model group 2 (5.58 ±2.39)IU/mg· min-1 was lower than the model control group(12.37±4.21)IU/mg· min-1,with significant differences (both P＜0.01).Conclusion Jinzhuyalong Ershiwuwei coral capsule could down regulate PLA2 activity in degenerated cervical intervertebral discs,and also decrease the production of some inflammaroty mediators.
