【摘要】：目的： 很長的時間里，人們對于吸煙的危害還主要在于吸煙者自身，而事實上并不如此。因為并不是所有的煙霧都直接進(jìn)了吸煙者的體內(nèi)，，很多人認(rèn)為其中大部分隨著呼出的二氧化碳被呼入到周圍的環(huán)境中被別人吸進(jìn)去，被動吸煙對人們的健康危害越來越明顯尤其是對絕經(jīng)后女性。被動吸煙可能會加速絕經(jīng)女性骨代謝，使骨質(zhì)疏松提前出現(xiàn)，希望通過動物實驗研究提供理論依據(jù)。 方法： 將40只Wister大白鼠隨機(jī)分成4組,A組：假手術(shù)；B組：去勢模型；C組：被動吸煙；D組：去勢+被動吸煙。分別于實驗1個月、2個月和3個月后測量大鼠代謝生化指標(biāo)：尿鈣及尿肌酐并計算出Ca/Cr比值、血清骨鈣素；骨密度測量,行組間對比。 結(jié)果: 實驗1個月：B組、與A組、C組骨密度、骨鈣素及尿Ca/Cr無差異（p0.05）；D組與A組、B組、C組骨密度、骨鈣素及尿Ca/Cr有差異（p0.05）；實驗2個月:B組與D組大鼠骨密有差異（p0.05）； B組與A、C組骨密度、骨鈣素及尿Ca/Cr有差異（p0.05）； D組與A、C組在骨密度、骨鈣素及尿Ca/Cr有差異（p0.05）；實驗3個月：B、D之間在骨密度、骨鈣素及尿Ca/Cr均有差異（p0.05）；同時B組在骨密度、骨鈣素及尿Ca/Cr方面顯著大于D組； 結(jié)論： 1、去勢大鼠給予被動吸煙，比單獨去勢及單獨給予被動吸煙更早出現(xiàn)骨代謝及骨密度變化，證實去勢大鼠骨密度及骨代謝生化指標(biāo)對被動吸煙更敏感。被動吸煙行為使去勢大鼠比不被動吸煙者更早出現(xiàn)骨質(zhì)疏松。即絕經(jīng)后女性的被動吸煙，使其更早出現(xiàn)骨質(zhì)疏松2、被動吸煙行為與絕經(jīng)后骨質(zhì)疏松有時間——效應(yīng)相關(guān)性，實驗3個月時，被動吸煙行為的去勢大鼠比不吸煙去勢大鼠骨質(zhì)疏松的嚴(yán)重程度，比實驗1個月時更嚴(yán)重。提示絕經(jīng)后被動吸煙時間越長，骨質(zhì)疏松的程度越嚴(yán)重。
[Abstract]:Objective: For a long time, the danger of smoking was mainly in the smoker himself, but not in fact. Because not all the smoke goes directly into the body of the smoker, many people think that most of it is breathed into the surrounding environment with the exhalation of carbon dioxide being sucked in by others. Passive smoking is more and more harmful to people's health, especially to postmenopausal women. Passive smoking may accelerate bone metabolism in menopausal women and make osteoporosis appear earlier. Methods: Forty Wister rats were randomly divided into 4 groups: sham operation group B: castrated model group C: passive smoking group D: castrated passive smoking group. After 1 month, 2 months and 3 months, the biochemical indexes of rat metabolism were measured: urine calcium and creatinine, the ratio of Ca/Cr, serum osteocalcin, bone mineral density, and the comparison between the two groups. Results: There was no difference in bone mineral density (BMD), osteocalcin and urinary Ca/Cr between group B and group A (1 month), and there was no difference in bone mineral density (BMD) between group D and group A (P 0.05). There was a significant difference in bone density between group B (n = 2) and group D (n = 2), and bone density between group B and group D (n = 2). There were significant differences in bone mineral density (BMD), osteocalcin (BGP) and urinary Ca/Cr (P 0.05) between group D and group A (P 0.05), and there were differences in bone mineral density (BMD), osteocalcin (BGP) and urinary Ca/Cr (P 0.05) between group D and group A (3 months), while in group B (group B), bone mineral density (BMD) was higher than that in group B (P < 0.05). Osteocalcin and urinary Ca/Cr were significantly higher in group D than in group D. Conclusion: 1. The changes of bone metabolism and bone mineral density in ovariectomized rats were earlier than those in ovariectomized rats. It was confirmed that bone mineral density and biochemical indexes of bone metabolism were more sensitive to passive smoking in ovariectomized rats. Passive smoking resulted in osteoporosis in ovariectomized rats earlier than in non-passive smokers. That is, passive smoking in postmenopausal women made them appear osteoporosis 2 earlier. Passive smoking behavior had a time-effect correlation with postmenopausal osteoporosis, and at 3 months of experiment, there was a time-effect correlation between passive smoking behavior and postmenopausal osteoporosis. The severity of osteoporosis in ovariectomized rats with passive smoking behavior was more serious than that in non-smoking castration rats. It suggested that the longer the passive smoking time after menopause, the more serious osteoporosis.
