Lipid resuscitation therapy is the administration of Intravenous Lipid Emulsions (ILE) with the intent of reducing the clinical manifestations of toxicity from drug overdoses; including local anesthetics, calcium-channel blockers, β- blockers, antipsychotics, tricyclic antidepressant drugs (TCAD) and other compounds. Although there are conflicting findings in the literature, ILE may be considered for resuscitation in emergency and intensive care in resuscitation of severe hemodynamic compromise by TCAD. This article reviews recent literature to analyse consequences, and intended effects associated with this treatment modality in poisoning with TCAD.
脂质复苏治疗是指静脉注射脂质乳剂(ILE)以减少药物过量毒性的临床表现;包括局部麻醉剂、钙通道阻滞剂、β受体阻滞剂、抗精神病药、三环抗抑郁药(TCAD)等化合物。尽管文献中存在矛盾的发现,但在TCAD严重血流动力学损害的复苏中,ILE可被考虑用于急诊复苏和重症监护复苏。本文回顾了最近的文献,分析了与TCAD中毒的这种治疗方式相关的后果和预期效果。

Background: The extensive uses of plants as medicines have been reported. However, the use of herbal products should be based on scientific origin; otherwise they would be useless and unsafe. The present study aims to evaluate the toxicity profile of oil of Thymus schimperi. Methods: For acute and sub-acute toxicity study, albino mice of both sexes were used. Skin irritation test was conducted on wistar rats. For the acute toxicity study, the essential oil was tested at three dose levels (1500, 1750 and 2000 mg/kg). A total of 10 mice were used for each dose level. Sub-acute toxicity study was done at a dose of 1000 mg/kg with 5 mice. For the skin irritation test, the essential oil was tested at two concentrations of 1% and 5% with 10 rats for both concentrations. Results: The results indicated that T. schimperi oil did not cause any mortality up to the limit doses of 2000 mg/kg. The essential oil did not cause significant weight change (p>0.05). The plant also did not cause significant increase in serum enzyme level of the study mice (p>0.05). The histopathological examination on liver and kidney showed that plant did not cause major organ damage. Ointment prepared from T. schimperi oil did not cause any abnormal skin reaction up on follow up for 14 days post treatment. Conclusion: It is concluded that the tested medicinal plant is safe as per animal study.
背景:植物作为药物的广泛用途已被报道。然而,草药产品的使用应该基于科学的来源;否则它们将是无用和不安全的。本研究旨在评价香胸腺油的毒性特征。方法:采用白化小鼠进行急性和亚急性毒性研究。对wistar大鼠进行皮肤刺激试验。在急性毒性研究中,以三种剂量水平(1500、1750和2000 mg/kg)对精油进行了测试。每个剂量水平共使用10只小鼠。以1000 mg/kg剂量对5只小鼠进行亚急性毒性研究。皮肤刺激试验采用1%和5%两种浓度的精油,10只大鼠分别进行两种浓度的实验。结果:香菇油在2000mg /kg的限定剂量下对大鼠无致死作用。精油对体重无显著影响(p < 0.05)。该植物也未引起研究小鼠血清酶水平的显著升高(p < 0.05)。肝脏和肾脏的组织病理学检查显示,植物未造成重大器官损伤。用香薷油配制的软膏在治疗后14天的随访中没有引起任何异常的皮肤反应。结论:经动物试验,该药用植物是安全的。

One of the most important medical emergency that results in sever morbidity and mortality is acute poisoning especially in developing countries. Young children contribute the majority of accidental poisoning cases all over the world. A retrospective analysis of poisoning calls received by the ministry of health Saudi Poisons Control Centers (Phone “937”) from the public as well as, from hospitals who registered poisoned patients during the one-year period (1st January to 31st December 2017) showed a total of 12566 calls. Children below 6 years of age constituted the vast majority of cases (84.2%).The majority of calls received were from public callers (87.3%). Males represented 57.9% of cases and Riyadh was the city with the largest number of calls received representing 37.5% of all calls. Furthermore, 98.5% of poisoning occurred at home, while 97.2% of exposures were accidental. We also found that 64.7% of public callers were advised to observe the patient at home and would not need to go to a hospital. Oral route of exposure constituted 95% of all routes of exposure. Drugs were the most common cause for poisoning consultations (59%) followed by household chemicals (25%). Non-toxic ingestions constituted 16% of all calls received. In conclusion, this study highlights the significance of raising public awareness of the risk factors and hazards present for household chemicals that children below 6 years of age are at higher risk of exposure to poisoning. In addition, Saudi Poisons Control Centers play a vital role in providing timely management guidelines for the management of poisoning cases thereby helping to save precious lives.
导致严重发病率和死亡率的最重要的医疗紧急情况之一是急性中毒,特别是在发展中国家。全世界意外中毒病例中,儿童占大多数。沙特卫生部毒物控制中心(电话“937”)在一年内(2017年1月1日至12月31日)从公众和登记中毒患者的医院接到的中毒电话进行回顾性分析,结果显示共有12566个电话。6岁以下儿童占绝大多数(84.2%)。大部分电话是公众来电(87.3%)。男性占57.9%,利雅得是接到电话最多的城市,占所有电话的37.5%。此外,98.5%的中毒发生在家中,而97.2%的暴露是意外的。我们还发现,64.7%的公众来电者被建议在家观察患者,不需要去医院。口腔暴露途径占所有暴露途径的95%。药物是中毒咨询最常见的原因(59%),其次是家用化学品(25%)。在所有接到的电话中,无毒摄入占16%。总之,这项研究强调了提高公众对家用化学品风险因素和危害的认识的重要性,即6岁以下儿童接触中毒的风险更高。此外,沙特毒物控制中心在为中毒病例的管理提供及时的管理准则方面发挥着至关重要的作用,从而帮助挽救宝贵的生命。

Neurotoxic exposures are common and ubiquitous in the environment, particularly in occupational settings. When a patient presents with toxic encephalopathy arriving at the correct diagnosis is often a diagnostic challenge. Recognition of toxic encephalopathy is important because the correct diagnosis of occupational hazards can prevent others (e.g, workers at the same workplace) from further exposure to the toxin. Polyvinyl chloride (PVC) plastics are extensively used for a very wide range of purposes. Before PVC can be made into finished products, it always requires conversion into a compound by the incorporation of additives such as heat stabilizers, UV stabilizers, plasticizers, processing aids, impact modifiers, thermal modifiers, fillers, flame retardants, biocides, blowing agents and smoke suppressors, and, optionally pigments. Lead, cadmium or organotins are used as stabilizers. Zinc, tin stabilizers and pigments are also used in PVC. Antimony-zinc complexes have been used as flame retardants in PVC products. We here present a case with acute encephalopathy due to accidental inhalation of PVC and heavy metal combination during the manufacture of electric wire.
在环境中,特别是在职业环境中,神经毒性暴露是常见和普遍的。当患者出现中毒性脑病时,正确诊断往往是一项诊断挑战。认识中毒性脑病很重要,因为对职业危害的正确诊断可以防止其他人(例如同一工作场所的工人)进一步接触毒素。聚氯乙烯(PVC)塑料广泛用于非常广泛的目的。在PVC可以制成成品之前,它总是需要通过加入添加剂,如热稳定剂、紫外线稳定剂、增塑剂、加工助剂、冲击改性剂、热改性剂、填料、阻燃剂、杀菌剂、发泡剂和抑烟剂,以及可选的颜料,转化为化合物。铅、镉或有机锡被用作稳定剂。锌、锡稳定剂和颜料也用于PVC。锑锌配合物已被用作PVC制品的阻燃剂。我们在此报告一例因在电线制造过程中意外吸入聚氯乙烯和重金属混合物而导致急性脑病的病例。

Mercury is a metal whose toxicity triggers neurological impairments at all ages, although the feti carry special risks. Mercury poisoning mostly occurs as a result of occupational accidents or attempted suicide. The bulk of evidence that addresses the health effects associated with long term postnatal mercury exposure is limited for all age groups. Public education on poisoning and the potential threats arising from mercury are of utmost importance for general well-being.
汞是一种金属,其毒性会引发所有年龄段的神经损伤,尽管胎儿有特殊的风险。汞中毒主要是由于职业事故或自杀未遂造成的。针对所有年龄组的长期产后汞接触对健康的影响的大量证据有限。对公众进行有关汞中毒和汞可能造成的威胁的教育,对公众健康至关重要。

Background: Cocaine is a commonly used illegal recreational drug and its consumption can produce various adverse health effects in animal and clinical studies. To date no information is available on whether exposed to cocaine will result in abnormally high plasma AChE activity in animals and whether it is characteristic of apoptosis. Our goals were to examine the relationship between enhanced AChE activity and cocaine-induced apoptosis and the possible underlying mechanisms. Methods: For this purpose, carboxylesterase and butyrylcholinesterase deficient ES1-/-BChE-/mice in strain C57BL/6 were treated intraperitoneally with 25 mg/kg cocaine daily for 8 days and sacrificed on day 9. Plasma AChE activity and body temperature were measured before and after treatment. Tissue sections from brain, heart, kidney, and liver were stained for AChE activity and apoptosis. Results: Mice had a 1°C decrease in surface body temperature at 10 min after cocaine treatment and the temperature returned to base line by 30 min. Plasma AChE activity in mice increased about 1.5-fold on days 7-8 and 1.75-fold on days 9 after cocaine treatment. More apoptotic cells were observed in liver sections of treated mice compared to controls. TUNEL-positive cells in the liver also stained heavily for AChE activity. Conclusions: AChE activity and apoptosis were both induced in carboxylesterase and butyrylcholinesterase knockout mice treated with cocaine. Their relationship might provide some novel information of cocaineassociated toxicity. Abnormally high plasma AChE activity may be an effect biomarker of cocaine exposure.
背景:可卡因是一种常用的非法娱乐性毒品,在动物和临床研究中,吸食可卡因会对健康产生各种不良影响。到目前为止,还没有关于暴露于可卡因是否会导致动物血浆乙酰胆碱酯酶活性异常升高以及这是否是细胞凋亡的特征的信息。我们的目的是研究乙酰胆碱酯酶活性增强与可卡因诱导的细胞凋亡之间的关系及其可能的潜在机制。方法:采用C57BL/6菌株羧酯酶和丁基胆碱酯酶缺陷小鼠ES1-/- bche -/腹腔注射可卡因25 mg/kg,连续8 d,第9天处死。治疗前后测定血浆乙酰胆碱酯酶活性和体温。脑、心、肾、肝组织切片染色检测乙酰胆碱酯酶活性和细胞凋亡。结果:小鼠在可卡因治疗后10 min体表温度下降1℃,30 min恢复到基线温度。小鼠血浆AChE活性在可卡因治疗后第7-8天和第9天分别升高1.5倍和1.75倍。与对照组相比,治疗小鼠肝切片中观察到更多的凋亡细胞。肝脏中tunel阳性细胞的乙酰胆碱酯酶活性也被大量染色。结论:可卡因可诱导羧酯酶和丁基胆碱酯酶敲除小鼠乙酰胆碱酯酶活性和细胞凋亡。它们之间的关系可能为可卡因相关毒性研究提供一些新的信息。异常高的血浆乙酰胆碱酯酶活性可能是可卡因暴露的一个有效的生物标志物。

The accidents by scorpion stings in Brazil, particularly in Belo Horizonte, capital of Minas Gerais state are caused by Tityus serrulatus species and accounts for fatal stings, especially in children and elderly people. The death in severe evenomation is caused by a circulatory shock, associated with respiratory and cardiovascular arrhythmias, cardiogenic shock, pulmonary edema, respiratory depression, acid-base disorders and serious coagulation disturbance. Our group has been involved in the study of several aspects of the mechanism of action of scorpion toxins injected in animals. However some aspects of the envenomation, such as, the regional blood flow distribution to several organs need further studies. The aim of the present work was to determine the flow to different organs after intravenous injection of the gamma fraction of toxins isolated from the T. serrulatus scorpion venom adding more information that would contribute to a better understanding of the pathophysiology of scorpion sting envenomation. The fluorescent microspheres deposition technique was used to evaluate the regional blood flow and regional vascular resistance of several organs in anesthetized rats after Tityus serrulatus scorpion venom (Tx) injection. Fluorescent microspheres of different colors were injected into the left ventricle through the carotid artery. Reference blood samples were collected from the left femoral artery at baseline (before) and 5, 15 and 30 min after toxin injection. Tissue samples from the adrenal gland, spleen, brain, heart, liver, ileum, mesentery, muscle, skin, lung and kidney were harvested and prepared for fluorescent measurements using a spectrophotometer. Hemodynamic parameters were monitored continuously. Blood flow variation was detected in the tissue samples and were different among the organs. The most common finding was a decrease in flow, varying with time and the severity of the intoxication. However, intrinsic mechanisms of auto-regulation of blood flow and vascular resistance possibly protect the heart and the brain from hypoperfusion after Tx injection.
在巴西,特别是在米纳斯吉拉斯州首府贝洛奥里藏特,蝎子蜇伤事故是由Tityus serrulatus物种引起的,并造成致命的蜇伤,特别是儿童和老年人。重症肺炎的死亡是由循环休克引起的,并伴有呼吸和心血管心律失常、心源性休克、肺水肿、呼吸抑制、酸碱失调和严重凝血障碍。本课题组参与了蝎子毒素在动物体内注射作用机制的几个方面的研究。然而,中毒的某些方面,如几个器官的区域血流分布,需要进一步研究。本研究的目的是测定经静脉注射的蝎毒γ部分毒素流向不同器官的情况,为更好地了解蝎毒刺中毒的病理生理学提供更多信息。采用荧光微球沉积技术对大鼠注射毒后的局部血流和局部血管阻力进行了评价。将不同颜色的荧光微球经颈动脉注入左心室。在基线(注射前)和注射毒素后5、15和30 min分别从左股动脉采集参考血样。收集来自肾上腺、脾脏、大脑、心脏、肝脏、回肠、肠系膜、肌肉、皮肤、肺和肾脏的组织样本,准备使用分光光度计进行荧光测量。连续监测血流动力学参数。在组织样本中检测到血流变化,并且在器官之间是不同的。最常见的发现是流量减少,随时间和中毒的严重程度而变化。然而,内在的血流自动调节机制和血管阻力可能保护心脏和大脑免受注射Tx后的低灌注。

However some aspects of the envenomation, such as, the regional blood flow distribution to several organs need further studies. The aim of the present work was to determine the flow to different organs after intravenous injection of the gamma fraction of toxins isolated from the T. serrulatus scorpion venom adding more information that would contribute to a better understanding of the pathophysiology of scorpion sting envenomation. The fluorescent microspheres deposition technique was used to evaluate the regional blood flow and regional vascular resistance of several organs in anesthetized rats after Tityus serrulatus scorpion venom (Tx) injection. Fluorescent microspheres of different colors were injected into the left ventricle through the carotid artery. Reference blood samples were collected from the left femoral artery at baseline (before) and 5, 15 and 30 min after toxin injection. Tissue samples from the adrenal gland, spleen, brain, heart, liver, ileum, mesentery, muscle, skin, lung and kidney were harvested and prepared for fluorescent measurements using a spectrophotometer. Hemodynamic parameters were monitored continuously. Blood flow variation was detected in the tissue samples and were different among the organs. The most common finding was a decrease in flow, varying with time and the severity of the intoxication. However, intrinsic mechanisms of auto-regulation of blood flow and vascular resistance possibly protect the heart and the brain from hypoperfusion after Tx injection.","PeriodicalId":15433,"journal":{"name":"Journal of Clinical Toxicology","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78589769","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}

Haloperidol is basically employed in combating mental disorder but its usage is controlled because of its adverse effects in other tissues. This study investigates the differential effects of phenolic compounds from black seed oil on key markers linked to testicular dysfunctions induced by Haloperidol in rat model. The animals were divided into six groups (n=10). Group I was given distilled water while Group II received 15 mg/kg body weight of haloperidol via oral route. Group III, IV and V were pre, co and post-treated with the oil, respectively at therapeutic dose of 150 mg/kg body weight. Lastly, Group VI was treated with black seed oil at dose of 150 mg/kg body weight; for 14 days. The results revealed an increase in 5I-nucleotidase and PACP activities with concomitant decrease of Δ5-3β-HSD, Δ5-17β-HSD and LDH activities in rats induced with haloperidol, followed by systemic oxidative damage and adverse histopathological changes in germinal epithelial cells. Co-treatment is most efficacious in preventing haloperidolinduced testicular damage in rat; followed by post and pre-treatment, respectively.
氟哌啶醇主要用于治疗精神障碍,但由于其对其他组织的不良影响,其使用受到控制。本研究探讨黑籽油中酚类化合物对氟哌啶醇致大鼠睾丸功能障碍关键标志物的差异影响。实验动物分为6组(n=10)。组1给予蒸馏水,组2给予氟哌啶醇15 mg/kg体重口服。III组、IV组和V组分别以150 mg/kg体重的治疗剂量进行预处理、预处理和后处理。最后,第六组用黑籽油处理,剂量为150 mg/kg体重;14天。结果显示氟哌啶醇诱导大鼠生发上皮细胞5i -核苷酸酶和PACP活性升高,同时Δ5-3β-HSD、Δ5-17β-HSD和LDH活性降低,随后出现全身氧化损伤和不良的组织病理学改变。联合治疗对氟哌啶酮致大鼠睾丸损伤的预防效果最好;分别为后处理和前处理。

Objectives: Lead is recognized as a serious pollutant on the basis of its persistence, toxicity, bioaccumulation and extensive use in industry. Exposure to lead results in a number of cytogenetical effects on freshwater biota which adversely affects the population, including reducing the rate of cell division and inducing mutations. In order to assess the toxicity of lead, a reliable model of Drosophila melanogaster was taken and experiments were carried out by maintaining a control set and experimental sets with varied concentrations of lead.Methods: The toxicity of lead was studied by varying the lead concentrations from 20-60 ppm in the food media that was given to the fruit flies. Studies on the larval, pupal and adult stages of the flies were done, including the reproductive and locomotion efficiency of the flies.Results: The results of our study shows that as the concentration of lead in the media increased from 20 to 60 ppm, there was a visible change in the number of offsprings and the locomotive behavior of flies. Significantly there was a stretch in the time duration in the conversion of larva to pupa and then pupa to adult. The length and width of the pupa was also found to be affected.Conclusion: Long term exposure to lead can have significant effect on the survival of population even if its concentration is low and it may also reflect population adaptive capacity.
目的:铅因其持久性、毒性、生物蓄积性和在工业中的广泛使用而被认为是一种严重的污染物。接触铅会对淡水生物群产生一些细胞遗传学影响,对种群产生不利影响,包括降低细胞分裂率和诱导突变。为了评估铅的毒性,建立了可靠的黑腹果蝇模型,并通过保持不同浓度铅的对照组和实验组进行了实验。方法:通过改变食物介质中铅的浓度从20- 60ppm给果蝇研究铅的毒性。对其幼虫期、蛹期和成虫期进行了研究,包括繁殖效率和运动效率。结果:我们的研究结果表明,随着介质中铅的浓度从20 ppm增加到60 ppm,果蝇的后代数量和运动行为发生了明显的变化。从幼虫到蛹再到蛹到成虫的转化时间有明显的延长。蛹的长度和宽度也受到影响。结论:即使铅浓度较低,长期暴露也会对种群的生存产生显著影响,也可能反映了种群的适应能力。

The main purpose of this study is to evaluate the ability of bradykinin potentiating factor (BPF) isolated from scorpion venom (Leiurus quinquestriatus) in treatment of liver injuries which induced by injection of CCl4 in male Albino rats. Male Albino rats (250±20 g body weight) were divided into four groups. In the control group; Albino rats were intraperitoneally (i.p) injected with 100 L saline solution. The second group (i.p) injected with BPF in 100 L saline solutions (1 gm/g. b. w. per 5 days). Third and fourth groups were i.p. injected with 0.5 ml/kg body weight (b. w.) twice weekly of CCl4 for fifteen days, after that only the fourth group was treated by BPF in 100 μL saline solutions (1 μgm/g. b. w. per 5 days). The results indicated that, CCl4 injection induced a significant decrease in serum catalase (CAT), Superoxide Dismutase (SOD), reduced glutathione (GSH), total protein and albumin, within thirty days post-injection of CCl4 as compared to the normal control group. In contrast, CCl4 induced a significant increase in Malondialdehyde (MDA), Aspartate Amino Transferase (AST), Alanine Amino Transferase (ALT), and Alkaline Phosphatase (ALP) compared to normal control animals. The efficiency of BPF treatment is alleviation the effects of CCl4 on these parameters. The improvement of these parameters may be attributed to the release antioxidant and cytokines and/or amelioration of the toxic effects of CCl4 on the liver.
本研究旨在探讨蝎毒缓激肽增强因子(BPF)对CCl4注射所致雄性白化大鼠肝损伤的治疗作用。体重250±20 g的雄性白化大鼠分为4组。在对照组;白化病大鼠腹腔注射100 L生理盐水。第二组(i.p)在100 L生理盐水溶液中注射BPF (1 gm/g)。每5天洗一次澡)。第3、4组小鼠每周2次腹腔注射0.5 ml/kg体重的CCl4,连续15 d,第4组小鼠仅在100 μL生理盐水溶液(1 μgm/g)中注射BPF。每5天洗一次澡)。结果表明,注射CCl4后30 d内血清过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、还原性谷胱甘肽(GSH)、总蛋白和白蛋白均显著低于正常对照组。与正常对照动物相比,CCl4诱导丙二醛(MDA)、天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)和碱性磷酸酶(ALP)显著升高。BPF处理的效率是减轻CCl4对这些参数的影响。这些参数的改善可能归因于释放抗氧化剂和细胞因子和/或改善CCl4对肝脏的毒性作用。
