为解决苏南丘陵区苜蓿苗期的杂草问题,从保护播种入手,在多年生黑麦草、一年生黑麦草、黑麦、小黑麦四种作物共五个品种中寻找适宜的伴生作物.通过对产量、株高、杂草率等多个指标测定分析,筛选出中新830小黑麦、赣选一号黑麦草适于用作苜蓿播种的伴生作物,同时获得两个苜蓿存活率最高的处理：苜蓿（15kg/hm^2）＋中新830小黑麦（150kg/hm^2）撒播及苜蓿（18 kg/hm^2）＋中新830小黑麦（250kg/hm^2）30cm条播.试验还表明撒播方式下,苜蓿播量与其竞争力不成正比。  相似文献

Comparison of morphology, viability, and function between blood and milk neutrophils from peak lactating goats          下载免费PDF全文

The morphological features of blood and milk neutrophils from peak lactating goats were compared using light microscopy, scanning electron microscopy and flow cytometry in order to investigate the cytological changes of neutrophils after migration into the mammary gland. The kinetics of reactive oxygen intermediates (ROI) generation and gelatinase release of blood and milk neutrophils, with or without stimulation of phorbol 12-myristate, 13-acetate ester (PMA), were used to characterize their responses to inflammatory stimuli. Neutrophils isolated from goat milk were highly segmented and contained multi-lobed nuclei. Ultrastructurally, milk neutrophils were more ruffled on the surface compared to blood neutrophils. Approximately 30% of milk neutrophils were undergoing cell death, either necrosis or apoptosis, in contrast to 8% of blood neutrophils. The ROI production of activated milk neutrophils peaked earlier than blood neutrophils, but the duration and the intensity were much less. Neutrophils from both sources augmented the release of gelatinase in response to PMA (1 ng/mL). However, the amount of gelatinase released from milk neutrophils was lower (P < 0.05) than that of blood neutrophils. In summary, more neutrophils become apoptotic and necrotic in the mammary gland, presumably due to spontaneous aging, the process of diapedesis, and the interaction with milk components. Milk neutrophils have impaired functionalities in comparison with blood neutrophils. The information is relevant when studying mammary gland immunity and related diseases, such as mastitis.  相似文献   

黑河流域水资源开发利用现状及存在问题分析   总被引：7，自引：0，他引：7

本文根据有关资料对黑河流域水资源的数量、分布与变化特征进行了较为详细的阐述 ,并且从可持续发展的内涵出发 ,分析了该地区水资源开发利用中出现的问题及对策。结果表明 ,黑河流域水资源开发利用中所出现的种种问题固然与西北内陆地区气候干旱等先天不利条件有很大的关系 ,但最主要的原因还是人类对水资源的开发利用不当所造成的。因此 ,必须改变传统的以牺牲生态环境为代价的经济发展模式 ,社会经济发展应充分考虑流域水资源的制约条件。  相似文献

Inhibitory effects of LDL-ACM complex on subcutaneous implanted tumors in nude mice()

AIM: In order to evaluate the applicable value of LDL as a targeted vehicle for chemotherapeutic agents, we investigated and compared the inhibitory effects of LDL-ACM complex and free ACM on nude mice's subcutaneous implanted tumors derived from gastric cancer cell lines, SGC-7901 and NKM-45. METHODS: LDL-ACM complex was prepared and the tumor model of nude mice was established by subcutaneous implantation of SGC-7901 and NKM-45. Then, the groups of nude mice developed subcutaneous implanted tumors were received either LDL-ACM complex or free ACM. Subsequently, the tumor size, weight and leukemia cell counts were measured and the rates of tumor-inhibition and the survival were compared among the groups. RESULTS: The inhibitory effects of LDL-ACM complex on the tumors, especially on SGC-7901 implanted tumors were much more obvious than that of free ACM. It was also indicated that the action of LDL-ACM complex was mediated by LDL receptor. CONCLUSION: These results showed that LDL-ACM complex had significant inhibitory effects on the implanted tumors and the effect might be mediated by LDL receptor.  相似文献   

The mechanisms of pathophysiological vasodilation or vascular hyporesponse     

KAI Li  HU De-yao  LIU Liang-ming 《园艺学报》2003,19(1):130-133

In some pathophysiological processes such as severe shock, the patients and animal experimental models fail to respond to pressor medicine. Vascular hyporesponse or vasodilation is one of the key problems in treatment of these patents. Although considerable progress had been made in recent years, the precise mechanisms of vascular contractile hyporeactivity have not been completely elucidated. A number of studies indicate that vascular hyporesponse or vasodilation correlate with many factors. In this review, the possible mechanisms about vascular hyporesponse or vasodilation during shock and other pathphysiolgoical processes were discussed.  相似文献
