Objective To observe the protective effect of the separate zinc gluconate oral and combined of Salvia injection on whole blood metal ion of calcium,magnesium,iron,copper and zinc concentration in noise-induced rats.Methods 50 female SD rats were randomly divided into a control group,a noise group,a zinc gluconate noise group (plus zinc group),a Salvia injection noise group (plus Salvia group) and a Zinc gluconate oral liquid and Salvia injection noise group (combined group),with10 rats in each group.Except the control group did not expose to noise,the rest groups were continuously exposed to high frequency steady noise for two weeks.Each group was compared for the concentration differences of whole blood metal ion of calcium,magnesium,iron,copper and zinc after the intervention of noise.Results ① In each group at the comparison of the calcium ion concentration: Calcium ion concentration of the control group(1.25± 0.16)mmol/L and the combination group(1.27 ± 0.10) mmol/L was significantly lower than the noise group (1.42 ± 0.18) mmol/L.The rest groups compared to each other were not statistically significant.②Magnesium ion concentration was highest in the noise group (1.53 ± 0.10)rmtmol/L),and lowest in the control group (130 ± 0.29) mmol/L,and the noise group was significantly higher than that of the control group.The mean of magnesium ion concentration in plus zinc group (1.42± 0.27) mmol/L,plus Salvia group (1.38± 0.15) mmol/L and combined group(l.37±0.11)mmol/L were lower than the noise group,but the difference was not significant (P＞0.05).③ The iron ion concentration of the noise group (5.47± 1.29)mmol/L was significantly lower than the other four groups (P＜0.05).The control group,plus zinc group,plus Salvia group,the combined group showed no significant differences.④ Whole blood copper ion concentration of the noise group (16.69 ± 4.18) μmol/L was significantly lower than the control group (21.53 ± 3.78) μmol/L and the combination group(19.53± 1.92)μmol/L with a statistical difference; compared with the control group,the concentration of copper ions in plus zinc group(16.19± 1.93)mμol/L was significantly lower (P＜0.05).⑤The whole blood zinc ion concentration in the noise group (50.83±7.99)μmol/L was significantly lower than the other groups,zinc ion concentration in the plus Salvia group (53.87±6.77)μmol/L was significantly lower than the control group (63.86± 8.83) μmol/L; the whole blood zinc ion concentration showed no difference between the plus zinc group (54.81 ± 5.90) μmol/L,plus Salvia group and combined group (59.21 ± 3.90) μmol/L.Conclusion Combined zinc gluconate oral solution and Salvia injection had protective effect on whole blood metal ion concentration affected by noise.The protection effect of zinc gluconate oral solution and Salvia injection combination was stronger than any individual.

Objective To investigate the effects of zinc gluconate combined with Danshen injection on the plasma lipid level following exposure to noise in rats. Methods Fifty female SD rats were randomly divided into a control group, a noise exposure group (model group), a zinc gluconate + noise exposure group (zinc gluconate group), a Danshen injection+noise exposure group (Danshen injection group) and a zinc gluconate+Danshen injection+noise exposure group (combination group), 10 rats in each group. The zinc gluconate group received intragastric administration of zinc gluconate 8-10 mg/(kg?d), the Danshen injection group received intraperitoneal injection of Danshen injection 6 mg/(kg?d), the combination group received intragastric administration of zinc gluconate 8-10 mg/(kg?d) and intraperitoneal injection of Danshen injection 6 mg/(kg?d). On the day 10, except in the control group, the rats in the rest of the groups were continuously exposed to high frequency steady noise for 7 days (4 000 Hz, 95 dB, 3 h/d). The serum levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. Results The serum levels of TC (1.88 ± 0.17 mmol/L vs. 1.55 ±0.09 mmol/L), TG (1.45 ± 0.38 mmol/L vs. 1.01 ± 0.27 mmol/L), LDL-C (0.29 ± 0.04 mmol/L vs. 0.23 ± 0.03 mmol/L) in the model group were significantly lower than those in the control group (P<0.01 or P<0.05), while the serum HDL-C level in the model group were significantly lower than that in the control group (0.55 ± 0.08 mmol/L vs. 0.62 ±0.06 mmol/L;P<0.01). The serum TC level in the zinc gluconate group was significantly lower than that in the model group (1.71 ± 0.11 mmol/L vs.1.88 ± 0.17 mmol/L;P<0.05). The serum levels of TC (1.73 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L) and LDL-C (0.25 ± 0.03 mmol/L vs. 0.29 ± 0.04 mmol/L) in the Danshen injection group were significantly lower than those in the model group(all P<0.05). The serum levels of TC (1.57 ± 0.21 mmol/L vs. 1.88 ± 0.17 mmol/L), TG (0.84 ±0.40 mmol/L vs. 1.45 ± 0.38 mmol/L) and LDL-C (0.24 ± 0.05 mmol/L vs. 0.29 ± 0.04 mmol/L) in the combination group were significantly lower than those in the model group (P<0.01 or P<0.05), and the serum HDL-C level (0.61 ± 0.07 mmol/L vs. 0.55 ± 0.08 mmol/L) in the combination group was significantly higher than that in the model group (P<0.05). Conclusions Noise exposure may induce dyslipidemias in rats. Zinc gluconate and Danshen injection can regulate the plasma lipid level following exposure to noise in rats, and combination of zinc gluconate and Danshen injection may be superior to zinc gluconate or Danshen injection alone.
