摘要:

文题释义:

芹菜素:主要存在于瑞香科、马鞭草科、卷柏科植物中,如芫花,卷柏中含量较大。芹菜素属于黄酮类,具有抑制致癌物质的致癌活性;作为治疗HIV和其他病毒感染的抗病毒药物;MAP激酶的抑制剂;治疗各种炎症;抗氧化剂;镇静、安神;降压。与其他黄酮类物质(槲皮素、山奈黄酮)相比具有低毒、无诱变性等特点。
骨密度:全称是骨骼矿物质密度,是骨骼强度的一个重要指标,以g/cm3表示,是一个绝对值。在临床使用骨密度值时由于不同的骨密度检测仪的绝对值不同,通常使用T值判断骨密度是否正常。T值是一个相对值,正常参考值在-1和+1之间。当T值低于-2.5时为不正常。骨密度,是骨质量的一个重要标志,反映骨质疏松程度,预测骨折危险性的重要依据。

背景:研究证实芹菜素具有抗病毒、抗炎、抗氧化、镇静安神等功效。

目的:研究不同剂量芹菜素对大鼠骨质疏松的疗效并探讨其机制。

方法:实验方案经南方医科大学动物实验伦理委员会批准。成年雌性SD大鼠42只,通过卵巢切除法建立大鼠骨质疏松模型,实验分为7组,每组6只大鼠,分别为假手术组、芹菜素20,40,60和80 mg/kg组、对照组、阳性对照组。假手术组未摘除卵巢,阳性对照组每天灌胃烯雌酚(0.02 mg/kg)、维生素D和钙;对照组给予同等量纯净水皮下注射;芹菜素各组分别给予相应剂量的芹菜素皮下注射;1次/d,用药8周。分别检测干预后第4周和第8周大鼠股骨密度和血清中钙、磷、骨碱性磷酸酶、Ⅰ型前胶原氨基末端前肽、β-Ⅰ型胶原C-末端肽的水平。

结果与结论:①与对照组比较,芹菜素剂量为40,60和80 mg/kg时,大鼠的骨密度、血清中钙、磷在第4周和第8周时均较高(P < 0.05),Ⅰ型前胶原氨基末端前肽、β-Ⅰ型胶原C-末端肽、骨碱性磷酸酶较低(P < 0.05);②与阳性对照组比,芹菜素剂量为60 mg/kg和80 mg/kg时,大鼠的骨密度、血清中钙、磷和骨碱性磷酸酶、Ⅰ型前胶原氨基末端前肽、β-Ⅰ型胶原C-末端肽在第4周和第8周时均无明显差别(P > 0.05),剂量为 20 mg/kg和 40 mg/kg时,骨密度、血清中钙、磷、均比阳性对照组低(P < 0.05),Ⅰ型前胶原氨基末端前肽、β-Ⅰ型胶原C-末端肽比阳性对照组高(P < 0.05);③对照组和假手术组比较,在第4周和第8周时大鼠骨密度、 血清中钙、磷均比较低(P < 0.05),Ⅰ型前胶原氨基末端前肽、β-Ⅰ型胶原C-末端肽均比较高(P < 0.05);④结果说明,去卵巢法建立大鼠骨质疏松模型确实有效;芹菜素对骨质疏松的治疗作用和剂量相关,一定剂量的芹菜素具有类似烯雌酚样的抗骨质疏松效果。

Abstract:

BACKGROUND: Apigenin has been shown to hold the effects of antivirus, anti-inflammation, anti-oxidation and tranquilizer and sedative.

OBJECTIVE: To study the effect of different doses of apigenin on osteoporosis in rats and to explore the underlying mechanism.

METHODS: The study was approved by the Laboratory Animal Ethical Committee of Southern Medical University. Forty-two adult male Sprague-Dawley rats were selected, and the rat models of osteoporosis were established by ovariectomy. The rats were divided into seven groups (n=6/group): the sham operation group, the control group, the positive control group, and the 20, 40, and 60, and the 80 mg/kg apigenin groups according to the dose of apigenin. The sham operation group did not receive the removal of the ovaries. The positive control group was supplemented with diethylstilbestrol (0.02 mg/kg), vitamin D and calcium daily. The control group was given the subcutaneous injection of same volume of purified water. The apigenin groups were given the subcutaneous injection of various doses of apigenin, respectively, once daily, for 8 weeks. The femoral bone mineral density and serum levels of calcium, phosphorus, bone alkaline phosphatase, amino-terminal propeptide of type I procollagen, C-terminal telopeptide of type I collagen were measured at 4 and 8 weeks after intervention, respectively.

RESULTS AND CONCLUSION: (1) Compared with the control group, when the dose of apigenin was 40, 60 and 80 mg/kg, the bone mineral density, and serum levels of calcium and phosphorus were increased significantly at 4 and 8 weeks (P < 0.05), and the levels of amino-terminal propeptide of type I procollagen, C-terminal telopeptide of type I collagen and bone alkaline phosphatase were decreased significantly (< 0.05). (2) Compared with the positive control group, when the dose of apigenin was 60 and 80 mg/kg, the bone mineral density, serum levels of calcium and phosphorus, the levels of amino-terminal propeptide of type I procollagen, C-terminal telopeptide of type I collagen and bone alkaline phosphatase showed no significant difference at 4 and 8 weeks (> 0.05). When the dose of apigenin was 20 and 40 mg/kg, compared with the positive control group, the bone mineral density, and serum levels of calcium and phosphorus were decreased significantly at 4 and 8 weeks (P < 0.05), and the levels of amino-terminal propeptide of type I procollagen, C-terminal telopeptide of type I collagen and bone alkaline phosphatase were increased significantly (P < 0.05). (3) Compared with the sham operation group, in the control group, the bone mineral density, and serum levels of calcium and phosphorus were decreased significantly at 4 and 8 weeks (P < 0.05), and the levels of amino-terminal propeptide of type I procollagen, C-terminal telopeptide of type I collagen and bone alkaline phosphatase were increased significantly (P < 0.05). (4) These results suggest that it is indeed effective to establish a rat osteoporosis model by ovariectomy. The therapeutic effect of apigenin on osteoporosis is dose-related, and a certain dose of apigenin has an anti-osteoporosis effect.
