Herbs can affect body function; therefore, when herbs are taken concurrently with drugs, interactions are possible. The interaction between drugs and herbal medicines is a safe concern and these interactions are especially important for drugs with narrow therapeutics index. The probability of herb-drug interaction can be higher than drug interaction, if conventional drug having single chemical entities, whereas most of the herbal medicinal product contain a mixture of pharmacologically active constituents. The herb-drug interaction may involve either an increase or decrease in the amount of drug in blood, either by altering the absorption, distribution, metabolism, and elimination (ADME) of drug and by antagonizing or synergism of the effect of drug or pharmacodynamics interaction may arise. This article we focus on how garlic interacts with conventional drug or it is favourable or not.
草药可以影响身体机能;因此,当草药与药物同时服用时,可能会发生相互作用。药物与草药之间的相互作用是一个安全问题,这些相互作用对治疗指标较窄的药物尤其重要。如果传统药物具有单一化学实体,则草药与药物相互作用的可能性可能高于药物相互作用,而大多数草药产品含有药理活性成分的混合物。草药-药物相互作用可能包括血液中药物量的增加或减少,或通过改变药物的吸收、分布、代谢和消除(ADME),或通过药物作用的拮抗或协同作用或药效学相互作用可能出现。本文将重点讨论大蒜与常规药物的相互作用,以及它是否有利。

Objective s: To explore the acute toxicity of major aquatic pollutants like mercuric chloride (HgCl 2 ) and polychlorinated by phenyls (PCB) and their effects based on the haematology of fresh water fish Danio rerio (Zebra fish). Methods : Zebra fish ( Danio rerio ) were exposed to progressive concentrations of HgCl 2 and PCB. The fishes were exposed to various concentrations of 5, 10, 20, 30, 40, 50 and 60 µg/L of mercury and PCB for a period up to two weeks. Haematological tests (total RBC, WBC count and haemoglobin concentration) were carried out on each concentration as well as control for a period of 2 weeks. Results : It was observed that, in exposure time from 0, 7 and 14 days, the total erythrocyte (RBC), leucocytes (WBC) haemoglobin (Hb) values decreased. The exposure to sub lethal doses of Mercury and PCB for 1, 7 and 14 days exposure period causes significant(Values are  expressed as means ± SD. Significant difference between groups were  compared to control, *p <0.01, **p <0.05) time and dose dependent alterations in total RBC, WBC and haemoglobin count compared to the control values. Conclusions : Haematological parameters constitute one of the important methods to access the health or ill health of an organism, subjected to intoxication. This demonstrates the physiological dysfunction of the haemopoietic system. Hgcl 2 is a heavy metal that causes symptoms in human like and gastrointestinal disturbances, anaemia, anorexia, loss of weight, chronic inflammations of kidneys. PCB exposure in animals has been reported to develop Wasting syndrome, reduced body weight, immune toxicity, vitamin A deficiency, and thyroid hormone deficiency, reproductive effects in offspring like reduced birth weight, abnormal gonad development. It also affect the central nervous system which results in slowed learning and memory loss, and also responsible for other behavioural changes. Thus toxicity bioassay is the basic tool for the detection, evaluation and abatement of water pollution
目的:探讨氯化汞(HgCl 2)和多氯联苯(PCB)等主要水生污染物对淡水鱼斑马鱼的急性毒性及其血液学影响。方法:斑马鱼(Danio rerio)暴露于逐渐浓度的HgCl 2和多氯联苯。鱼被暴露在5、10、20、30、40、50和60µg/L不同浓度的汞和多氯联苯中长达两周。血液学测试(红细胞总数、白细胞计数和血红蛋白浓度)对每个浓度进行,并进行为期2周的对照。结果:观察到,暴露时间为0、7和14天,总红细胞(RBC)、白细胞(WBC)、血红蛋白(Hb)值下降。暴露于亚致死剂量的汞和多氯联苯1、7和14天的暴露期导致显著(数值以平均值±标准差表示)。与对照组相比,组间差异有统计学意义(*p <0.01, **p <0.05),总RBC、WBC和血红蛋白计数与对照组相比,时间和剂量依赖性增高。结论:血液学参数是判断中毒生物体健康与否的重要方法之一。这证明了造血系统的生理功能障碍。Hgcl - 2是一种重金属,可引起人体和胃肠道紊乱、贫血、厌食症、体重减轻、肾脏慢性炎症等症状。据报道,动物接触多氯联苯会出现消瘦综合征、体重减轻、免疫毒性、维生素A缺乏症和甲状腺激素缺乏症,对后代的生殖影响,如出生体重减轻、性腺发育异常。它还会影响中枢神经系统,导致学习和记忆减退,还会导致其他行为变化。因此,毒性生物测定法是检测、评价和治理水污染的基本手段

Hgcl 2 is a heavy metal that causes symptoms in human like and gastrointestinal disturbances, anaemia, anorexia, loss of weight, chronic inflammations of kidneys. PCB exposure in animals has been reported to develop Wasting syndrome, reduced body weight, immune toxicity, vitamin A deficiency, and thyroid hormone deficiency, reproductive effects in offspring like reduced birth weight, abnormal gonad development. It also affect the central nervous system which results in slowed learning and memory loss, and also responsible for other behavioural changes. Thus toxicity bioassay is the basic tool for the detection, evaluation and abatement of water pollution","PeriodicalId":19998,"journal":{"name":"Pharmaceutical and Biological Evaluations","volume":"20 1","pages":"52-58"},"PeriodicalIF":0.0,"publicationDate":"2017-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82752549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective : The objective of the present study is to produce silver nanoparticles from marine fungi from south west coastal areas of Tamil Nadu and evaluating their potentials with special reference to anticancer activity. Methods : Hand core pushing technique is adapted to collect marine sediment samples along the coastal environs. Distinguished Aspergillus colonies were isolated and identified by wet mount procedure. The characterized Aspergillus consortium was subjected to produce silver nanoparticles. The extracellularly synthesized nanoparticles were characterized. Silver nanoparticles were evaluated for anticancer activity against MCF7 cell line by MTT assay. The IC 50 values were determined. Results : Aspergillus consortium consist of A. niger, A. michelle and A. japonicus . Silver nanoparticles were extracellularly synthesized by the reduction of silver nitrate (AgNO 3 ) to metallic silver (Ag + ) ions results in the transformation of pale yellow to dark red colour. Constant shift was observed at 420 nm while monitoring the solution by UV-Vis spectrophotometer. The presence of important functional groups like –NH 3 was confirmed by FT-IR Spectroscopy. Anticancer activity of the silver nanoparticles was evaluated against MCF7. There was 100% cell inhibition when concentration of the AgNPs reached 25 µg, 50 µg and 100 µg respectively in the test solution. Notably the IC 50 value was found to be very lowest for the nanoparticles produced by A. japonicus and the value was found to be 1.47 µg/ml. Conclusions : Aspergillus consortium was found to be an ideal mycobiosystem for the production of silver nanoparticles with potential anticancer activity.
目的:从泰米尔纳德邦西南沿海地区的海生真菌中制备纳米银,并评价其抗癌活性。方法:采用手推岩心法采集沿海地区海相沉积物样品。采用湿法分离鉴定了曲霉菌落。用表征的曲霉联合体制备纳米银。对细胞外合成的纳米颗粒进行了表征。采用MTT法评价银纳米颗粒对MCF7细胞株的抗癌活性。测定IC 50值。结果:曲霉联合体由黑曲霉、米歇尔曲霉和日本曲霉组成。通过硝酸银(agno3)还原成金属银(Ag +)离子,在细胞外合成了纳米银,其颜色由淡黄色变为深红色。紫外-可见分光光度计监测溶液时,在420 nm处观察到恒定的位移。FT-IR光谱证实了- nh3等重要官能团的存在。研究了银纳米颗粒对MCF7的抗癌活性。当AgNPs浓度分别达到25µg、50µg和100µg时,细胞抑制率为100%。值得注意的是,日本刺参纳米颗粒的ic50值最低,为1.47µg/ml。结论:曲霉联合体是生产具有潜在抗癌活性的纳米银的理想真菌生物系统。
