AIM:To probe into the toxicological mechanism of sulfur dioxide (SO2) and its derivatives on cardiovascular system.METHODS: Effects of tea polyphenols (TP) on the increase in sodium current (INa) induced by SO2 derivatives in the cardiomyocytes were studied using the whole cell patch-clamp technique.RESULTS: ① The increase in INa induced by SO2 derivatives was inhibited by treating the cells with TP at different concentrations (10, 20 or 50 mg/L) in a dose dependent manner. At concentration of 50 mg/L, TP completely inhibited the increase in INa by SO2 derivatives. ② SO2 derivatives led to shift left of the activation curve. After application of TP at dose of 50 mg/L, the curve showed resumed significantly. ③ TP changed the inactivation process significantly. Before and after the application of SO2 derivatives, the half-inactivation voltage of INa was -(71.94?0.23) mV and -(65.79?0.69) mV (n=8, P0.05).CONCLUSION: TP inhibits the incremental effects of SO2 derivatives on INa, suggesting that the toxicity of SO2 on cardiomyocytes of rat is induced by free radical.

BACKGROUND:Carboxymethylated chitosan is shown to promote some kinds of cells proliferation, but its effects on proliferation of Schwann cells need further studies.
OBJECTIVE:To investigate the effects of carboxymethylated chitosan on proliferation of Schwann cells and expression of nuclear factor-κB in cultured Schwann cells.
METHODS:Schwann cells from Sprague-Dawley rats at logarithmic growth phase were seeded in 96-wel plates, and cultured respectively with PBS, 0, 10, 50, 100, 200, 500, 1 000 mg/L carboxymethyl chitosan for 24 hours. cellproliferation was detected using the cellcounting kit-8 assay. After trypsin digestion, Schwann cells from Sprague-Dawley rats at logarithmic growth phase were used to prepare cellsuspensions, which were seeded in 6-wel cellculture plates and cultured respectively with 50, 100 and 200 mg/L carboxymethyl chitosan and PBS for 24 hours. Then, 5-bromo-2-deoxyuridine, real-time PCR and western blot assay were performed.
RESULTS AND CONCLUSION:cellcounting kit-8 and 5-bromo-2-deoxyuridine detection results showed that carboxymethyl chitosan at 50-1000 mg/L, especial y at 200-500 mg/L, could promote Schwann cellproliferation. Real-time PCR and western blot results showed 50-200 mg/L carboxymethyl chitosan could promote nuclear factorκB mRNA and protein expression in Schwann cells in a dose-dependent manner, suggesting carboxymethyl chitosan can promote Schwann cellproliferation and expression of nuclear factor-κB in Schwann cells cultured in vitro.

OBJECTIVETo investigate the effects of Pyrroloquinoline quinine (PQQ) on hydrogen peroxide-induced apoptosis of Schwann cells (SCs) and its mechanism.

METHODSSCs were isolated and cultured in vitro, and identified by S-100 immunofluorescence staining. The cultured SCs were divided into control group, hydrogen peroxide-treated group, hydrogen peroxide and PQQ treated groups. The intracellular superoxide dismutase (SOD) and malondialdehyde (MDA) content was detected; the apoptotic rate of SCs induced by hydrogen peroxide was determined by flow cytometry assay. The Hoechst33342 staining was used to detect the nuclear fragmentation and apoptotic nuclear condensation of SCs; the Rhodamine123 staining was used to detect the changes of mitochondrial membrane potential in SCs, the Western blot analysis was used to detect the expression of Bcl-2 in hydrogen peroxide induced SCs.

RESULTSThe SOD activity was significantly decreased and MDA level was increased in H2O2 induced SCs (P < 0.05), after addition of PQQ, the SOD content increased and MDA content decreased (P < 0.05). Flow cytometry results showed that the early apoptotic rate was 58.8% in H2O2 induced SCs, which has significant difference compared with the control group (P < 0.05), after addition of 10, 50, 100 nmol/L PQQ, the apoptotic rates were reduced to 33.7%, 18.7%, 3.9% respectively, showing significantly different with injured group (P < 0.05). Hoechst 33342 staining showed that H2O2 induced SCs had typical morphological characteristics, such as uptake of nuclear chromatin, nuclear shrinkage, nuclear fragmentation phenomenon. The proportion of apoptotic cells after PQQ treatment reduced. Rhodamine staining results showed that the H2O2 induced mitochondrial membrane potential reduction in SCs, which was reversed by addition of PQQ. Western blot analysis showed that the expression of Bcl-2 was decreased in H2O2 induced SCs, while it increased significantly after addition of PQQ (P < 0.05).

CONCLUSIONPQQ has a protective effect on oxidative stress-induced apoptosis of SCs.
