目的:使用实验性糖尿病Wistar大鼠模型验证五桠果(Dillenia indica)甲醇提取物的生物活性成分(乙酸乙酯馏分)的降血糖及降血脂作用。方法:通过腹腔内注射链脲佐菌素(60mg/kg)建立大鼠1型糖尿病模型,腹腔内注射烟酰胺(120mg/kg)15min后腹腔内注射链脲佐菌素(60mg/kg)建立大鼠2型糖尿病模型。在不同的实验模型中,用药组大鼠均分别给予200mg/kg和400mg/kg的五桠果甲醇提取物的乙酸乙酯馏分连续21d。使用血糖仪每周1次测定各组大鼠血糖水平。使用自动分析仪器分别测定各组大鼠血清总胆固醇、三酰甘油及高密度脂蛋白胆固醇水平。结果:在两个实验模型中,与模型组比较,五桠果甲醇提取物的乙酸乙酯馏分均能显著降低模型大鼠的血糖水平(P<0.01)以及血清总胆固醇(P<0.05)和三酰甘油(P<0.05)含量,升高高密度脂蛋白胆固醇水平(P<0.05)。结论:五桠果甲醇提取物的乙酸乙酯馏分在400mg/kg剂量时,对于1型及2型糖尿病模型大鼠具有显著的治疗作用。因此这种提取物有望被研究开发成为治疗糖尿病的又一替代药物。

Forest Ecosystems 2019年第1期6卷 67-75页

作者： Satyam verma Dharmatma Singh Ajeet Kumar Singh Shanmuganathan Jayakumar Environmental Informatics and Spatial Modeling Lab Department of Ecology and Environmental Sciences School of Life Sciences Pondicherry University Landscape Level Planning and Management Wildlife Institute of India

Background: The effect of forest fire on soil is complex and relatively less understood than its above ground *** the effect of fire on forest soils can allow improving management of valuable forest ecosystems as adequate and proper information is very important for efficient management. We have studied the recovery of soil properties after fire, using a chronosequence approach(two, five and fifteen years after fire and control). Soil samples were collected from each plot of four fire patches(B0, B2, B5 & B15) from three different depths viz. 0–10(Top), 10–20(Middle), and 20–30 cm(Bottom).Results: Soil organic carbon was lower than unburned plots after the fire and could not recover to the level of unburned plot(B0) even in 15 years. Total N, available P, and extractable K were lower 2-years and 5-years after the fire but are higher than unburned plot after 15-years. Available nitrogen(NO_3^- and NH_4^+) remain unchanged or higher than B0 in burned patches. Soil pH, Bulk Density, Water Holding Capacity, and Electrical Conductivity was lower initially after the fire. Forest fires have affected soil properties considerably. The response of soil properties varied with years after fire and soil ***: Forest fires occur very frequently in the study area. Significant quantities of carbon and total nitrogen are lost to the atmosphere by burning of litter, duff, and soil om. Because nitrogen is one of the most important soil nutrients, the recapture of N lost by volatilization during a fire must receive special attention. Long-term studies are required to better understand the recovery of soil nitrogen.

罂粟的种植据说是在15世纪引入印度的。大约17世纪中叶,印度已成为鸦片的主要产地,具体产地包括比哈尔(Bihar)和马尔瓦(Malwa)两个主要地区,以及印度中部的其他地区。;关于比哈尔,我们已知的第一个关于该地区鸦片产量的数据来自1688年。根据这个估算,该地区在正常年份的年产量为4350箱,每箱2孟德(Maunds,亚洲部分地区的重量单位, 1孟德约等于37公斤)。
