Long-term exposure to incense smoke alters metabolism in Wistar albino rats

The burning of incense is an important source of indoor air pollution in Asia. We assessed the effect of long‐term exposure to incense smoke on the body weight and levels of circulating glucose, triglycerides, total cholesterol, HDL‐cholesterol, insulin, adiponectin and leptin in Wistar albino rats. Two groups of rats were used. First group (n = 12) was exposed daily to incense smoke for 4 months at the rate of 4 g day^?1 in the exposure chamber. Another group of rats (n = 12), was used as non‐exposed control. Blood samples were collected from all animals after 4, 8, 12 and 16 weeks of exposure. Serum glucose, triglycerides, total cholesterol and HDL‐cholesterol, LDL‐cholesterol insulin, adiponectin and leptin were measured. Our results showed that incense smoke exposure was associated with decreased weight gain and the adverse metabolic changes of increased triglycerides and decreased HDL‐cholesterol concentrations. Exposure to incense was also associated with a transient increase of leptin levels. Taken together, these data suggest that incense smoke influences metabolism adversely in rats. The effect of incense smoke on human health and the underlying mechanisms need to be studied further. Copyright © 2011 John Wiley & Sons, Ltd.     

黛力新联合中药熏香治疗慢性肾衰竭伴发抑郁焦虑的效果研究

目的:探讨黛力新联合中药熏香治疗慢性肾衰竭伴发抑郁焦虑的临床效果。方法:将我院自2017年10月至2018年9月收治的慢性肾衰竭伴发抑郁焦虑患者65例作为研究对象,按照随机数字表法将其分为研究组33例和对照组32例,研究组患者给予黛力新联合中药熏香进行治疗,对照组患者给予黛力新进行治疗,观察和比较两组患者抑郁自评量表(Self-rating depression scale,SDS)、焦虑自评量表(Self-Rating Anxiety Scale,SAS)及社会支持评定量表(social support rate scale,SSRS)量表评分的变化情况。结果:治疗前,两组患者SAS、SDS、SSRS评分比较差异均无统计学意义(P0.05)。治疗后,两组患者的SAS和SDS情绪评分均较治疗前明显降低,SSRS评分均较治疗前明显升高,且研究组SAS和SDS情绪评分明显低于对照组,而SSRS评分显著高于对照组(P0.05)。研究组患者治疗依从率为96.97%,口干、恶心、头晕、纳差等轻度不良反应发生率为30.30%,均明显高于对照组(84.38%和12.50%,P0.05),两组患者在治疗过程中均未出现明显的恶性不良反应,研究组患者上述不良反应在停止熏香治疗后自行缓解。结论:黛力新联合中药熏香梅花香和安神香用于治疗慢性肾衰竭伴发抑郁焦虑患者能够有效的缓解患者抑郁、焦虑的不良情绪,提高社会支持和治疗依从率。
