Abstract:
Objective To screen the optimal dose of Tangtong Formula in vitro. Methods RSC96 Schwann Cells were cultivate by DMEM mediums which contains different concentrations of glucose (5–125 mmol/L). The prevention effects of Tangtong Formula at different concentrations (0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 3.0, 5.0 mg/mL) on the proliferation of RSC96 Schwann Cells induced by high glucose were detected. After the RSC96 Schwann Cells were cultivated in 100 mmol/L and 125 mmol/L high glucose mediums for 72 h, the apoptosis of RSC96 Schwann Cells was detected by flow cytometry Annexin V/PI, and the apoptosis rate was calculate; the proliferation situation of RSC96 Schwann cells in different times was detected by CCK-8 method. Results RSC96 Schwann cells were in apoptosis after being intervened by 100 mmol/L and 125 mmol/L high glucose mediums. The apoptosis rates were respectively(7.46±0.96)％ and(16.53±1.01)％, with statistical significance compared with control group (P<0.01). Different concentrations of Tangtong Formula could alleviate the inhibitory effect of high glucose on the proliferation of RSC96 Schwann cells, and the threshold concentration of Tangtong Formula in 24 h was 0.25 mg/mL. The concentrations of Tangtong Formula in 0.5 mg/mL, 1.0 mg/mL, and 1.5 mg/mL could inhibit the apoptosis of RSC96 Schwann cells induced by high glucos, compared with 125 mmol/L high glucose group, the apoptosis rate of RSC96 Schwann cells decreased significantly (P<0.05, P<0.01). Conclusion Among three different doses, when the dose of Tangtong Formula is in 1.5 mg/mL, the effects on inhibiting apoptosis are the best.
