Pharmacological effects
1. Inhibition of lipofuscin and scavenging of free radicals: mice intraperitoneal injection of pearl powder suspension 200mg/(kg.day) × 25 days, can make the myocardium and brain tissue in the content of lipofuscin is significantly reduced, there is no significant effect on liver tissue. PFC extracted from pearl powder of the triangular mussel and its isolated product were determined by chemiluminescence method to determine their effects on O radicals. The results showed that both of them inhibited luminescence, and the purified monomer component of PFC, PCM-1, had a stronger effect and could inhibit the free radical reaction in vivo.
2. Anti-tumor effects: mice injected intraperitoneally with PFC40mg/(kg.day)×9 days had significant inhibition of subcutaneous inoculation of S180 sarcoma cells 8.0×l05 cells/ml (P<0.01), inhibition rate of 34.8%; the same dose of the drug can inhibit the subcutaneous inoculation of Lewis lung carcinoma homogenate 5.0×10 cells/ml mice, inhibition rate of 13.8%. mice with an inhibition rate of 13.89%, but there was no statistical difference. The same dose of the drug prolonged the survival time of mice inoculated with P388/J lymphoid leukemia by 14.75% (P<0.05), while significantly reducing the spleen weight of the animals by 24.12% (P<0.01). For in vitro cultured P388/J cells, two dose groups, PFC 50μg/ml and 100μg/ml, showed a killing rate of 25.O% and 24.8%, respectively, at 72 hours of dosing (P<0.01).
3. Other effects: pearl extract had an inhibitory effect on isolated rabbit intestine.
