Heavy metal accumulation in medicinal plants collected from environmentally different sites

Objective To estimate the heavy metal content in soil and selected medicinal plants procured from environmentally different sites of the same city. Methods Soil and plant samples of Abutilon indicum, Calotropis procera, Euphorbia hirta, Peristrophe bycaliculata, and Tinospora cordifolia were collected from 3 environmentally different sites of the city： heavy traffic area （HTA）, industrial area （IA）, and residential area （RA）. Pb by inductively coupled plasma emission spectrometry and compared Cd, Cr, and Ni were estimated in soil and plant samples Results The level of heavy metal was higher in soil than in plant parts studied. Accumulation of heavy metals varied from plant to plant. Pb was the highest in Calotropis procera root from HTA site and the lowest in Peristrophe bycaliculata whole plant from IA site. It was also lower in residential area than in heavy traffic area. Conclusion The level of heavy metal content differed in the same medicinal plant collected from environmentally different sites of the same city. Thus, it reiterates our belief that every medicinal plant sample should be tested for contaminant load before processing it further for medication.     

Sustainability of cosmetic products in Brazil

Background  The most recent research in the area of cosmetics to sustainability has focused on obtaining formulations rich in nontraditional oils and butters from seeds and fruits native to Brazilian tropical flora. These have contributed to aggregate value for the raw materials and involvement of small farms forming rural production in Brazil, since the plants are cultivated in preservation areas sponsored by companies who are partners in the Government Program for Brazilian Sustainability. Given that the oils extracted from seeds have the potential to replace these cutaneous constituents, it has been verified that new products of strong commercial impact show an increasing tendency to incorporate in their formulas the oils of plants grown in Brazilian soil.     

HACCP在进口水产品加工过程卫生监管中的应用

为了加强对进口水产品原料进行来料加工的卫生监督管理．进一步提高出口产品的卫生质量．我们应用了危害分析和关键控制点(HACCP)的系统方式。评估进口加工全过程中相关的危害分析(HA)．确立需要控制和监测的关键控制点(CCP)．指导加工企业建立一种自行应用的卫生质量保证体系．以确保整个水产品加工全过程中的安全性和可靠性。

重用生白术和莱菔子治疗功能性便秘68例

目的观察重用生白术和莱菔子治疗功能性便秘的临床疗效。方法选择68例功能性便秘患者,以重用生白术和莱菔子的理气润肠通便方药治疗4周,观察便秘改善情况。结果治疗4周后,患者的排便间隔时间和排便时间较治疗前显著减少(P0.05),总有效率为95.58%。结论重用生白术和莱菔子对功能性便秘具有较好的疗效。     

白术水提物抑瘤作用及其机制研究

目的:研究白术水提物的抑瘤作用,并从调节免疫功能角度探讨其抑瘤机制。方法:以S180荷瘤小鼠为研究对象,给予不同剂量的白术水提物10 d,称取瘤重,计算胸腺指数、脾指数,同时利用放射免疫测定法检测血浆肿瘤坏死因子α(TNF-α)、白介素-2(IL-2)的含量。结果:白术各剂量组和模型组瘤重及胸腺指数有显著性差异(P<0.01或P<0.05),白术中剂量组对TNF-α和IL-2均有显著性影响(P<0.01或P<0.05)。结论:白术可以调节S180荷瘤小鼠免疫功能,抑制肿瘤生长,并呈现出一定的剂量效应关系。     

上海市市售禽肉中金黄色葡萄球菌污染的半定量风险评估

目的了解上海地区生牛乳中金黄色葡萄球菌污染状况,产肠毒素特性及细菌耐药性。方法采集上海地区4家奶牛场共计306份生牛乳, 按照GB4789.10《食品安全国家标准食品微生物学检验金黄色葡萄球菌检验》进行金黄色葡萄球菌的分离鉴定及毒素测定,并对检出的金黄色葡萄球菌根据临床与实验室标准化协会(CLSI)推荐的微量肉汤稀释法进行药敏试验,定量测定最低抑菌药物浓度(MIC)。结果共检出金黄色葡萄球菌32株, 检出率为10.5%;其中17株产肠毒素阳性, 阳性率为53.1%;对上述金黄色葡萄球菌株进行12种抗生素的耐药检测,其中耐药最严重的是青霉素、氨苄西林、红霉素、四环素,耐药率分别达78.1%、65.6%、53.1%、21.9%,并表现出多种耐药谱。结论上海地区生牛乳中金黄色葡萄球菌污染及其肠毒素产毒能力较强,耐药情况严重,这与奶牛养殖过程中抗生素暴露有关,建议上海地区奶牛场扩大对奶牛乳腺炎治疗的药物筛选范围,根据药物敏感实验结果合理选择抗菌药物。
