OBJECTIVE To evaluate whether or not administration of folic acid and resveratrol have preventive effects on cleft palate formation as well as the comparison of the two drugs' s effects. METHODS Pregnant mice were randomly divided into 9 groups, with 8 mice in each group. The TCDD group mice were dosed with TCDD 28 microg/kg body weight on gestation day 10 (GD 10) animals in folic acid group were respectively dosed with folic acid 15, 10, 5 mg/kg and TCDD 28 microg/kg; resveratrol treated mice were divided into 3 groups: resveratrol 50 mg/kg were orally administered for 6 consecutive days, from gestational day GD 8 to GD13 in resveratrol (GD8-13 ) group; resveratrol 50 mg/kg were orally administered for 6 consecutive days, from gestational day GD 8 to GD13, followed hy an oral administered with TCDD on GD10 in resveratrol (GD8-13) + TCDD group; resveratrol 50mg/kg and TCDD 28 microg/kg were used by gavage administration at GD10 in resveratrol (GD10) + TCDD group. Control mice were treated with the same volume of water for 6 consecutive days from GD8 to GD13 and were given a single dose of corn oil on GD10. The pregnant mice weight and embryos, the number of live, cleft palate, dead and resorption fetal mice were recorded on GD 17.5. The coronal sections of the fetal mice heads were prepared at GD 17.5 and observed by microscopy. RESULTS Total frequency of clefts was 92.86% in TCDD group, 84.00% (15 mg), 73.08% (10 mg), 84.00% (5 mg) in folic acid + TCDD groups, 0% in resveratrol (GD10) group, 74.51% (GD10), 57.78% (GD8-13) in resveratrol + TCDD groups. The frequency of cleft was 0% in the control group. Compared with the control and the TCDD groups, there were significant differences in the number of live, dead and resorption fetal mice in TCCD + resveratrol (GD8-13) group (P < 0.05). No significant differences in embryonic weight, live fetuses weight, the number of live, dead and resorption fetal mice were found in the other groups (P > 0.05). CONCLUSION Test dose of folic acid and resveratrol both had certain antagonistic effect on cleft palate in mice induced by TCDD, with folic acid 10 mg/kg, resveratrol 50 mg/kg GD8-13 doses having stronger antagonistic action. Effects of both the two drugs have no significant difference, but resveratrol (50 mg/kg, GD8-13) significantly affects the fetal mice's growth and development under TCDD exposure in utero.

叶酸和白藜芦醇对TCDD诱导的小鼠pa裂的拮抗作用

目的评估叶酸和白藜芦醇的使用是否对c裂的形成有预防作用,并比较两种药物的作用。方法将妊娠小鼠随机分为9组,每组8只。TCDD组小鼠在妊娠第10天给予TCDD 28微克/千克体重(GD 10),叶酸组动物分别给予叶酸15、10、5mg / kg和TCDD 28微克/千克。白藜芦醇治疗的小鼠分为三组:白藜芦醇(GD8-13)组从妊娠第8天至第13天连续6天口服给予50mg / kg白藜芦醇,连续6天。从妊娠第8天至GD13连续6天口服白藜芦醇50 mg / kg,随后在白藜芦醇(GD8-13)+ TCDD组中口服GD10的TCDD口服;白藜芦醇(GD10)+ TCDD组以GD10灌胃施用白藜芦醇50mg / kg和TCDD 28 microg / kg。从GD8至GD13,连续6天以相同体积的水处理对照小鼠,并在GD10上给予单剂量玉米油。GD 17.5记录了怀孕小鼠的体重和胚胎,活着的、,裂的,死亡的和再吸收的胎儿小鼠的数量。以GD 17.5制备胎儿小鼠头部的冠状切片,并通过显微镜观察。结果TCDD组c裂总频率为92.86%,叶酸+ TCDD组为84.00%(15 mg),73.08%(10 mg),84.00%(5 mg),白藜芦醇(GD10)组为0%,74.51% (GD10),白藜芦醇+ TCDD组中的比例为57.78%(GD8-13)。对照组of裂的发生率为0%。与对照组和TCDD组相比,TCCD +白藜芦醇(GD8-13)组的活鼠,死鼠和再吸收胎鼠的数量有显着差异(P <0.05)。在其他组中,胚胎重量,活胎儿重量,活,死和再吸收胎儿小鼠的数量均无显着差异(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠pa裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13剂量具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。与对照组和TCDD组相比,TCCD +白藜芦醇(GD8-13)组的活鼠,死鼠和再吸收胎鼠的数量有显着差异(P <0.05)。在其他组中,胚胎重量,活胎儿重量,活,死和再吸收胎儿小鼠的数量均无显着差异(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠c裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。与对照组和TCDD组相比,TCCD +白藜芦醇(GD8-13)组的活鼠,死鼠和再吸收胎鼠的数量有显着差异(P <0.05)。在其他组中,胚胎重量,活胎儿重量,活,死和再吸收胎儿小鼠的数量均无显着差异(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠c裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。TCCD +白藜芦醇(GD8-13)组的死胎和吸收胎小鼠(P <0.05)。在其他组中,胚胎重量,活胎儿重量,活,死和再吸收胎儿小鼠的数量均无显着差异(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠pa裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13剂量具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。TCCD +白藜芦醇(GD8-13)组的死胎和吸收胎小鼠(P <0.05)。在其他组中,胚胎重量,活胎儿重量,活,死和再吸收胎儿小鼠的数量均无显着差异(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠pa裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13剂量具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。在其他组中发现了死亡的和吸收性的胎鼠(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠pa裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13剂量具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。在其他组中发现了死亡的和吸收性的胎鼠(P> 0.05)。结论叶酸和白藜芦醇均对TCDD诱导的小鼠pa裂有一定的拮抗作用,其中叶酸10 mg / kg,白藜芦醇50 mg / kg GD8-13剂量具有较强的拮抗作用。两种药物的作用均无显着性差异,但白藜芦醇(50 mg / kg,GD8-13)在子宫内暴露于TCDD的情况下会显着影响胎鼠的生长发育。
