游泳加中药淫羊藿综合疗法对去势大鼠血脂的影响 总被引:2,自引:0,他引:2
罗丽娜 《吉林体育学院学报》2008,24(4):98-99
妇女绝经后雌激素的缺乏易导致骨质疏松的发生,也易导致绝经期机体脂代谢的紊乱。利用去势大鼠骨质疏松模型,观察了游泳、中药淫羊藿以及游泳加中药等几种防治手段对去势大鼠血脂主要生化指标的影响。结果表明:中药淫羊藿、游泳以及游泳加中药淫羊藿综合疗法等几种防治方法均能通过降低甘油三酯(TG)、低密度脂蛋备(LDL)防治去势大鼠发生高血脂从而避免引发心脑血管疾病,其中游泳加中药淫羊藿综合疗法降脂作用要优于单纯运动及中药组。 相似文献

改良广播体操对男性大学生机体血脂代谢的影响 总被引:1,自引:0,他引:1
观察改良广播体操对30名男性大学生机体血脂代谢的影响。选择无遗传病史,无经常锻炼史的30名男性大学生为受试对象,每天进行两次30 min多组数的改良广播体操锻炼,锻炼强度以心率来控制,要求锻炼后心率在125次/min左右。观察受试者实验前、锻炼后第15 d、30 d、45 d晨安静空腹状态下,TG、TC、HDL-C、LDL-C和瘦素等指标变化。结果表明:45 d每天两次30 min、多组数的有氧广播体操锻炼可显著降低机体血浆TG和TC,预防TG堆积;HDL-C和HDL-C/LDL比值显著升高。说明有氧广播体操锻炼可使血浆脂蛋白的分布得到有效改善,从而预防和有效抵抗AS发生。 相似文献

有氧运动和大豆多肽对高脂饮食大鼠胰岛素抵抗形成和血脂代谢的干预作用 总被引:5,自引:0,他引:5
目的 :探讨有氧运动和补充大豆多肽对高脂饮食大鼠胰岛素抵抗形成的干预作用及其机制.方法 :在给SD大鼠喂饲高脂饮食的同时,进行10周的有氧运动锻炼或/和补充大豆多肽,实验结束时测定空腹血糖(FPG)、空腹胰岛素(FINS)、血清甘油三酯(TG)、胆固醇(TC)和游离脂肪酸(FFA)等指标,并计算胰岛素敏感性指数(ISI)、稳态模型-IR指数(HOMA-IR).结果:1)10周的高脂饮食可使大鼠FPG、FINS、HOMA-IR指数显著升高,而ISI指数显著降低;2)在高脂饮食诱导大鼠IR形成的同时,进行10周60 min的有氧运动锻炼或补充SPH,可以显著降低高脂饮食大鼠FPG、FINS、HOMA-IR指数,提高ISI指数;与此同时,运动联合补充SPH可使高脂饮食大鼠FINS、HOMA-IR指数进一步降低,跚进一步升高,但无显著性差异;3)HF组大鼠血清TG、TC和FFA显著高于对照组,运动训练或补充SPH可使高脂饮食大鼠血清TG、TC和FFA含量显著降低,且具有显著的交互作用.结论 :1)10周的高脂饮食可以诱导大鼠IR的形成;2)运动训练或补充SPH可以显著地预防高脂饮食大鼠IR的形成,而且,运动锻炼联合补充SPH在一定程度上对预防高脂饮食大鼠IR的形成具有促进作用.3)高脂饮食诱导大鼠m的形成机制与高脂饮食大鼠血脂代谢紊乱有关;而运动训练或补充SPH可以改善血脂代谢来预防m的形成. 相似文献

There is growing evidence that damage to spermatozoa by reactive oxygen species play a key role in male infertility. The aim
of this study was to assess seminal plasma free 8-Isoprostane levels in men with asthenozoospermia, asthenoteratozoospermia
and oligoasthenoteratozoospermia compared to normozoospermic males and its correlation with seminal parameters. The case group
consisted of men with asthenozoospermia (n=15), asthenoteratozoospermia (n=16) and oligoasthenoteratozoospermia (n=15). The
control group consisted of 16 males with normozoospermia. After Purification of Free 8-Isoprostane by affinity column, its
concentration was measured by enzyme immunoassay method. Free 8-Isoprostane evaluation showed significantly greater values
in the total case group (n=46) versus control group (18.23±3.56 vs 2.6±0.38 ng/ml). In each case group free 8-Isoprostane
also showed a significant increasing compared to normozoospermic males. Free 8-Isoprostane showed an inversely significant
correlation with sperm motility and sperm morphology. Lipid peroxidation could have significant role in etiology of sperm
abnormalities. Measurement of 8-Isoprostane can be used as a specific biomarker for assessing lipid peoxidation in sperm. 相似文献

The study was conducted to find out the extent of lipid peroxidation and antioxidant status in ischemic stroke patients (ISPs)
with and without diabetes. Malondialdehyde (MDA) was studied as a marker of lipid peroxidation. Glutathione (GSH), uric acid
and ceruloplasmin were estimated to study the antioxidant potential of ISPs. Significantly higher levels of MDA were found
in both the groups of ISPs and the increase in MDA was more in ISPs without diabetes. GSH levels were decreased significantly
in both the groups of ISPs and maximum decline was found in ISPs with diabetes. Uric acid levels were significantly increased
in both the groups of ISPs. Ceruloplasmin levels were increased significantly in ISPs without diabetes, whereas its levels
were slightly decreased in ISPs with diabetes. A negative correlation was found between MDA and the antioxidants GSH, uric
acid and ceruloplasmin in ISPs with diabetes. This study suggests that there is an association between ischemic stroke and
increased oxidative stress and the antioxidant potential is impaired in both the groups of ISPs with and without diabetes. 相似文献

The response of liver lipid peroxidative and antioxidant defense system of protein undernourished rats to liver regeneration
induced by partial hepatectomy was examined in rats. Animals were divided into four groups; A,B,C and D of four animals each.
Animals in group A were maintained on 16% casein diet while those in groups B, C and D were placed on low-protein diet (5%
casein) for fourteen weeks and fed ad libitum. 72 hours before sacrifice, partial hepatectomy was carried out on animals in
group D while animals in group C were sham-operated. The results show that protein undernutrition induced an increase in lipid
peroxidation but reduced catalase activity, glutathione level and superoxide dismutase activity when compared with well-nourished
rats. Liver regeneration however, resulted in significant increases in lipid peroxidation and catalase activity but significant
reductions in glutathione level and superoxide dismutase activity in protein undernutrition rats when compared with their
sham-operated counterparts. These results suggest that liver regeneration induced by partial hepatectomy exacerbates lipid
peroxidation in protein undernutrition rats and that Catalase plays a major role in the mopping up of reactive oxygen species
generated following liver regeneration in partially hepatectomised protein undernutrition rats. 相似文献

急性太极拳运动对原发性高血压患者血压和血脂的影响 总被引:3,自引:0,他引:3
目的:探讨急性太极拳运动对原发性高血压患者血压和血脂的影响及其可能的作用机制。方法:以原发性高血压患者14人为研究对象,采用自身对照法,用DS-250型动态血压测量仪(美国产),观察休息日和运动日24小时动态血压变化。测定运动结束后即刻、24小时、48小时血清总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)的动态变化。结果:与运动前相比,一次急性太极拳运动后,原发性高血压患者收缩压和舒张压都呈下降趋势,舒张压下降的程度更加明显(P<0.05)且更为持久,这种降压效应可持续18个小时以上,24小时后基本恢复到运动前水平。一次急性太极拳运动后即刻TC、LDL-C浓度明显下降(P<0.05),HDL-C浓度显著上升(P<0.05);运动后24小时HDL-C浓度持续升高(P<0.01),TG浓度明显下降(P<0.05),LDL-C回升并超过运动前水平;48小时后TC、TG、LDL-C的浓度基本恢复到运动前水平,HDL-C浓度仍然较高,但与运动前相比没有达到显著性差异。 相似文献
