文题释义:
胡椒碱:用于白兰地添加剂,使有辛辣味,也可作为杀虫剂。此外,它还是中国治疗癫痫验方(白胡椒和萝卜)中主要抗惊厥成分为食品业中用作辛辣味原料,具杀菌作用。
骨吸收:此过程是破骨细胞的破骨过程。当骨组织的某处在一特定的时间需要重建时(如微创伤-疲劳骨等),先有一组破骨细胞被激活(包括单核前体细胞→破骨细胞前体→破骨细胞成熟、活性提高),迁移并黏附于吸收部位的矿化骨基质上(即矿化骨表面),融合成多核巨细胞,并发生极化。当骨吸收增加、或骨新生减少、或二者并存时,即发生骨丧失,使牙槽骨高度降低。
 
摘要
背景:胡椒碱在胰腺炎模型、痛风模型、大脑中动脉梗死模型中具有抗炎、抗氧化以及免疫调节作用,但其对牙周炎模型的作用效果目前尚未清楚。
目的:观察胡椒碱对实验性大鼠牙周炎模型骨吸收和胶原降解的保护作用。
方法:采用3-0的手术丝线结扎大鼠下颌第一磨牙牙颈部建立牙周炎模型,在建模前1 d分别灌胃胡椒碱50,100 mg/kg,并设健康对照组和模型组作对比,建模后8周进行相关检测。
结果与结论:①CT定量分析结果:与健康对照组相比,模型组的第一磨牙釉牙骨质界到牙槽嵴顶的距离明显降低(P < 0.05),胡椒碱50,100 mg/kg组牙槽骨破坏程度较模型组明显改善(P < 0.05);②相关因子蛋白表达:与模型组相比,胡椒碱100 mg/kg组基质金属蛋白酶8,13和白细胞介素1β蛋白表达明显下调(P < 0.05),胡椒碱50 mg/kg组基质金属蛋白酶8蛋白表达明显下调(P < 0.05);③胶原纤维染色形态:与模型组相比,胡椒碱50,100 mg/kg组的胶原纤维排列较为整齐,胶原纤维面积明显增加(P < 0.05);④结果证实:胡椒碱能降低牙周炎模型牙槽骨吸收程度,减轻胶原纤维的降解,保护牙周组织,其机制与抑制基质金属蛋白酶8,13和白细胞介素1β蛋白表达有关。

Abstract:

BACKGROUND: Piperine in models of pancreatitis, gout, middle cerebral artery infarction has anti-inflammatory, antioxidant and immune regulatory effects, but its effects on periodontitis model are not clear.

OBJECTIVE: To observe the protective effect of piperine on bone absorption and degradation of collagen in experimental rat models of periodontitis.
METHODS: Rat models of periodontitis were established by ligaturing the dental cervix of rat mandibular first molar with 3-0 silk. On day 1 before model establishment, rats were intragastrically administered piperine 50 and 100 mg/kg. There were healthy control group and model group. Related detection was performed 8 weeks after model establishment.
RESULTS AND CONCLUSION: (1) Results of quantitative CT analysis: compared with the healthy control group, the distance from the first molar enamelo-cemental junction to the alveolar ridge crest was significantly lower in the model group (P < 0.05). The degree of alveolar damage was significantly improved in the 50 and 100 mg/kg piperine groups compared with the model group (P < 0.05). (2) Related factor protein expression: compared with the model group, matrix metalloproteinase-8, -13 and interleukin-1β protein expression was significantly decreased in the 100 mg/kg piperine group (P < 0.05); matrix metalloproteinase-8 protein expression was significantly decreased in the 50 mg/kg piperine group (P < 0.05). (3) Collagen fiber morphology: compared with the model group, collagen fibers arranged orderly and collagen fiber area significantly increased in the 50 and 100 mg/kg piperine groups (P < 0.05). (4) Results confirmed that piperine could reduce the alveolar bone resorption, reduce the degradation of collagen fibers and protect the periodontal tissues in models of periodontitis. Its mechanism is associated with the inhibition of matrix metalloproteinase-8, -13 and interleukin-1β protein expression.
