In present work, effect of plant derived smoke exposure on wheat (Triticum aestivum L.) seeds germination and post germination response has been studied in laboratory. Plant derived smoke was generated by burning of plant material (leaf, straws etc.) in a special designed furnace. Non-imbibed and imbibed seeds of wheat were exposed to plant derived smoke for 1 hr time duration. Best results were observed in non-imbibed seeds treated with plant derived smoke while imbibed seeds showed poor response to germination percentage, germination index, seedling vigor index and root shoot length. It has been proved from present study that plant derived smoke has stimulatory effect on germination & post germination response of non-imbibed seeds while it may cause inhibitory effect in imbibed seeds of wheat.展开更多
目的 探讨中老年男性颈动脉硬化病人吸烟偏好及动脉硬化相关影响因素的状况。方法 选择2017年6月—2018年11月于某三甲医院查体和就诊符合本研究纳入标准的中老年男性277例,收集人口学、生活习惯和既往病史资料,同时完成E-Prime 2.0软...目的 探讨中老年男性颈动脉硬化病人吸烟偏好及动脉硬化相关影响因素的状况。方法 选择2017年6月—2018年11月于某三甲医院查体和就诊符合本研究纳入标准的中老年男性277例,收集人口学、生活习惯和既往病史资料,同时完成E-Prime 2.0软件编制的香烟及钱币决策偏好任务,并行颈动脉血管超声检查。根据颈动脉超声结果将受试者分为硬化组和非硬化组,分析吸烟决策偏好与颈动脉硬化发生的关系,以及各相关因素对颈动脉硬化的影响。结果 硬化组对香烟的选择次数和选择总次数较非硬化组均明显增加,差异有统计学意义( t =3.811、3.936, P <0.01);吸烟硬化组对香烟的选择次数和选择总次数较吸烟非硬化组均明显增加,差异有统计学意义( t =2.393、2.045, P <0.05)。硬化组在年龄、吸烟、饮酒、高血压、糖尿病、高脂血症等方面较非硬化组均明显升高,差异有统计学意义(χ^2 =6.807~26.589, P <0.01)。二元Logistic回归分析结果显示,年龄、饮酒、高血压、糖尿病、高脂血症是颈动脉硬化发生的独立影响因素,而吸烟决策偏好不是颈动脉硬化发生的独立影响因素。结论颈动脉硬化者与非硬化者在吸烟决策偏好上存在差异,但吸烟决策偏好不是颈动脉硬化的独立影响因素。年龄、饮酒、高血压、糖尿病、高脂血症是颈动脉硬化发生的独立影响因素。展开更多
目的:研究黄芪合剂对被动吸烟引起小鼠超氧化物歧化酶(superox ide d ism u tase,SOD)活性和脂质过氧化物(lip id perox ide,LPO)含量的影响。方法:以超氧化物歧化酶活性和脂质过氧化物为指标,采用邻苯三酚自氧化法和荧光法测定SOD的活...目的:研究黄芪合剂对被动吸烟引起小鼠超氧化物歧化酶(superox ide d ism u tase,SOD)活性和脂质过氧化物(lip id perox ide,LPO)含量的影响。方法:以超氧化物歧化酶活性和脂质过氧化物为指标,采用邻苯三酚自氧化法和荧光法测定SOD的活性和LPO的含量。结果:黄芪合剂可使被动吸烟降低的SOD活性升高,可使被动吸烟升高的LPO降低。结论:黄芪合剂有抗脂质过氧化作用,对被动吸烟引起小鼠超氧化物歧化酶活性和脂质过氧化物含量的改变有保护作用。展开更多
