Effects of Prostate Water Pellets on the number of colonies, NO concentration and NOS activity in the prostate tissue of CBP rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the effects of Prostate Water Pellets (PWP) on the number of colonies, NO concentration and NOS activity in the prostate tissues of rats with chronic bacterial prostatitis (CBP).</p><p><b>METHODS</b>A total of 120 healthy adult male Wistar rats weighing 250-300 g were equally randomized into 6 groups: blank control, model control, positive control, high-dose PWP, medium-dose PWP and low-dose PWP. The CBP rat models were established by injecting colibacilli (10(7)/ml) into the prostate. A month later, the high- , medium- and low-dose PWP groups were treated intragastrically with PWP at 4.4 g/kg, 2.2 g/kg and 1.1 g/kg per day respectively, the positive controls with levofloxacin at 0.018 g/kg per day, and the blank and model controls with normal saline, all for 35 days. Then the numbers of colonies in the prostate tissues were measured, and the changes in NO concentration and NOS activity detected by the nitrite reductase method.</p><p><b>RESULTS</b>Compared with the model controls, the number of colonies, NO concentration and NOS activity were significantly reduced in the prostate tissues of the rats of the high- , medium- and low-dose PWP groups (P < 0.01).</p><p><b>CONCLUSION</b>PWP was proved to be efficacious for CBP in rats, whose mechanism might be related with its inhibitory effect on bacterial growth and decreasing effect on NO concentration and NOS activity in the prostate tissues.</p>

Biomass structure analysis of Atractylodes lancea in different ecological environments / 中国中药杂志

<p><b>OBJECTIVE</b>To study the ecological environments of Atractylodes lancea by biomass structural analysis.</p><p><b>METHOD</b>Through the scientific investigation in Maoshan, the sampling spots were set up, the relation between growth and ecological environments was researched and the ecological environments of A. lancea were divided as following: the vegetation layer, the shrub layer, the shrub-weed layer and the weed layer. The ramet biomass, height, leaves and coverage of A. lancea were studied.</p><p><b>RESULT</b>The several factors (ramet biomass, height, leaves and coverage) showed the regular change. Among maximum, minimum and average, the shrub layer was the biggest, the shrub and weed layer was the second biggest and the vegetation layer and the weed layer was the least.</p><p><b>CONCLUSION</b>A. lancea tends to distribute in the shrub layer and the shrub-weed layer.</p>

Remote sensing resource monitoring on Atractylodes lancea / 中国中药杂志

Remote sensing technology was used for investigation of the resources of Atractylodes lancea. Firstly, the general situation of Jiangshu Maoshan and A. lancea in Maoshan was introduced; Secondly, the methods of remote sensing on the resource of the wild drugs were explained. Thirdly, the TM images were interpret according to the differences of the objects reflex spectrum, and growth environments in Damao mountain, Ermao mountain and Xiaomao mountain were divided into different sub-areas according to the results of the field investigations. Finally, the resource of A. lancea in Jiangshu Maoshan was estimated.

Comparing of different methods on habitat adaptive division of Chinese material medica / 中国中药杂志

<p><b>OBJECTIVE</b>To comparing two kinds habitat adaptive division of Chinese material medica with different models.</p><p><b>METHOD</b>The habitat adaptive divisions of A. lancea according essential oil accumulation with two kinds pattern, model pattern and template pattern were carrid and compared.</p><p><b>RESULT</b>Two habitat adaptive divisions of A. lancea maps according essential oil accumulation were gotten.</p><p><b>CONCLUSION</b>Both model pattern and template pattern were efficient on habitat adaptive division of Chinese material medica, but they shoud bu used with different processesd and based different background [corrected]</p>

Remote sensing monitoring methods for medicinal plants resource in different types of ecological environment / 中国中药杂志

Different remote sensing monitoring methods are needed for the medicinal plant resource in different types of ecological environment. This paper explained remote sensing monitoring methods for the resource of the wild medicinal plants and cultivated plants, and analyzed the rare species, generous species and species in special ecological environment in detail. It provides a new method to all kind of medicinal plants resources' remote sensing monitoring.
