Background: Epilepsy is one of the most common neurological conditions and a significant cause of morbidity and mortality. Objectives: The present study aimed to evaluate the anticonvulsant activity of the petroleum ether extract of the root of Anacyclus pyrethrum on Pentylenetetrazole (PTZ)-induced seizure model in Wistar rats. Methods: The composition of the petroleum ether extract of A. pyrethrum was first analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). Subsequently, the anticonvulsant activities of these extracts (70 and 140 mg/kg, intraperitoneal injection) were evaluated on PTZ-induced seizures in rats. The protection rate against induced seizures, latency, and duration of seizures, as well as neurological symptoms, were assessed and compared to those protected by phenobarbital. Results: GC/MS analysis of the petroleum ether extract showed that the main components were octadecadienoic acid, hexadecanoic acid, diheptylcyclopropene, naphthalene, and methyl stearate. The extract (70 and 140 mg/kg) was found to provide significant protection against PTZ-induced seizures. Moreover, compared to the negative control, the extracts increased the latency of induced-convulsion and reduced the duration of epilepsy. Interestingly, the extracts showed a reduction in neurological symptoms and the severity of seizures compared to the negative control. All of these outcomes manifested in a dose-dependent manner. Conclusion: The petroleum ether extract of A. pyrethrum may produce anticonvulsant effects by reducing the duration of seizures and delaying the latency of seizures induced by PTZ.
背景:癫痫是最常见的神经系统疾病之一,也是发病率和死亡率的重要原因。目的:研究拟除虫菊根石油醚提取物对戊四唑(PTZ)致痫模型Wistar大鼠的抗惊厥作用。方法:首先采用气相色谱-质谱联用技术对除虫菊石油醚提取物进行成分分析。随后,研究了这些提取物(70和140 mg/kg,腹腔注射)对ptz诱导的大鼠癫痫发作的抗惊厥活性。评估了对诱发性癫痫发作的保护率,癫痫发作的潜伏期和持续时间,以及神经系统症状,并将其与苯巴比妥的保护率进行了比较。结果:经GC/MS分析,石油醚提取物的主要成分为十八二烯酸、十六烷酸、二庚基环丙烯、萘和硬脂酸甲酯。发现提取物(70和140 mg/kg)对ptz诱导的癫痫发作具有显著的保护作用。此外,与阴性对照相比,提取物增加了诱发惊厥的潜伏期,缩短了癫痫持续时间。有趣的是,与阴性对照相比,提取物显示神经症状和癫痫发作的严重程度有所减轻。所有这些结果都表现为剂量依赖性。结论:除虫菊石油醚提取物可能通过缩短PTZ诱发的癫痫发作时间和延长癫痫发作潜伏期来发挥抗惊厥作用。

Hamideh Abbaspour Kasgari, H. Samaee, S. A. Samakkhah, Parisa Moradimajd
In late December 2019, a global outbreak (pandemic) of the coronavirus was reported, which WHO named 2019-nCoV. The virus is now spreading rapidly and has affected manycountries, including Iran. There is no definitive and effective treatment for this virus yet. This report aimed to define the effect of Tocilizumab in patient with COVID-19. This case report isabout a 52-year-old man with COVID-19 that has been treated with tocilizumab. The reported patient had an acceptable improvement in oxygen saturation but no significant change inlung CT scan. After 3 days treatment patient with Tocilizumab, extensive bilateral lungs involvement still exist but SPO2 level iimprovement up to 90%. According to the results, thisdrug had a positive impact on oxygen saturation. However, we cannot be certain whether this drug positively affected the patient’s coronavirus disease.
2019年12月下旬,报告了冠状病毒的全球爆发(大流行),世卫组织将其命名为2019- ncov。该病毒目前正在迅速传播,并影响了包括伊朗在内的许多国家。目前还没有针对这种病毒的明确有效的治疗方法。本报告旨在确定Tocilizumab在COVID-19患者中的作用。本病例报告涉及一名接受托珠单抗治疗的52岁男性COVID-19患者。本例患者血氧饱和度改善可接受,但肺部CT扫描无明显变化。Tocilizumab治疗3天后,患者仍存在广泛的双侧肺受累,但SPO2水平改善高达90%。结果表明,该药对血氧饱和度有积极影响。但是,我们不能确定这种药物是否对患者的冠状病毒病有积极影响。

E. Zaboli, R. Ghasemian, M. Abounoori, Mohammad Zahedi, S. Hashemi
The novel coronavirus disease 2019 (COVD-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The immunothrombosis could occur during infectionwith viruses. Deep vein thrombosis (DVT) is a devastating condition that usually involves the lower extremities. The typical course of DVT is associated with an episode of enormous limbswelling and pain. In this case report, we aimed to present one of the COVID-19 possible complications: DVT in a 38 years old man infected with SARS-CoV-2. A 38 years old manpresented with leg pain. He had a dry cough and fatigue suspicious symptoms of COVID-19. For further evaluations, the lung Computed Tomography scan (CT-scan), labratoricalassessments, and doppler sonography of the common femoral vein (CFV) of both legs were done. Also, for investigating the other underlying causes of DVT, abdominopelvic CT-scan andlumbosacral Magnetic Resonance Imaging (MRI) were done. The CT-scan showed GroundGlass Opacity (GGO) view. Labratorical assessment proposed a thrombotic condition. Thedoppler sonography of the CFV of both legs revealed a massive thrombosis in the left CFV suggesting an acute DVT. Abdominopelvic CT-scan and lumbosacral MRI were negativefor other underlying causes of DVT. COVID-19 is associated with the classical syndrome named disseminated intravascular coagulation and the subsequent consumption coagulopathypresented as DVT.
新型冠状病毒病2019 (covid -19)是由严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)引起的。感染病毒时可发生免疫血栓形成。深静脉血栓形成(DVT)是一种通常累及下肢的毁灭性疾病。深静脉血栓的典型病程与剧烈的肢体肿胀和疼痛有关。在本病例报告中,我们旨在介绍COVID-19可能的并发症之一:一名感染SARS-CoV-2的38岁男性的DVT。男性,38岁,腿部疼痛。他有干咳和疲劳症状,疑似新冠肺炎。为了进一步评估,进行了肺部计算机断层扫描(ct)、实验室评估和双腿股总静脉(CFV)的多普勒超声检查。此外,为了调查DVT的其他潜在原因,进行了腹部骨盆ct扫描和腰骶核磁共振成像(MRI)。ct扫描显示磨玻璃不透明(GGO)。实验室检查提示血栓形成。双下肢CFV多普勒超声显示左侧CFV大量血栓形成提示急性DVT。腹部骨盆ct扫描和腰骶MRI未发现其他潜在的DVT原因。COVID-19与称为弥散性血管内凝血的经典综合征以及随后的消耗性凝血途径(表现为DVT)有关。

Chemoprophylatic, Ayurvedic, Homeopathic Approaches for COVID-19 Prophylaxis 化学预防、阿育吠陀、顺势疗法方法预防COVID-19
Ramakant Yadav, K. Pathak, D. Pathak, Raj Kumar
The world is grappling for US FDA-approved therapies for Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2). It is the virus that has caused Coronavirus Disease 2019 (COVID-19). Several pharmacological drugs are under various phases of clinical trials, and their current clinical use is primarily based on the in vitro activity against SARS-CoV-2 or related coronaviruses. While the efficacy of drug therapies is yet to be established, and the efficacy of the vaccine for COVID-19 is to be accomplished, we need to focus on prophylactic measures. The current article describes the chemoprophylactic, Ayurvedic, homeopathic, and Unani prophylactic approaches for combating COVID-19 based on the guidelines issued by the Ministry of AYUSH, India. The article is based on the guidelines issued by the Ministry of AYUSH, India. The proposed approaches have been supported by scientific evidence. The article also provides an outlook on the global scenario of herbal practices. In the absence of effective treatment, efforts to control the COVID-19 pandemic heavily rely on non-pharmaceutical interventions such as personal preventive measures. The alternative system of medicine offers prophylactic solutions that are simple and inexpensive. These simple measures will go a long way in tackling the pandemic.
世界正在努力争取美国fda批准的治疗严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)的疗法。它是导致2019冠状病毒病(COVID-19)的病毒。一些药理药物正处于不同的临床试验阶段,目前的临床应用主要基于对SARS-CoV-2或相关冠状病毒的体外活性。虽然药物治疗的疗效尚未确定,COVID-19疫苗的疗效有待实现,但我们需要把重点放在预防措施上。本文根据印度阿尤什部发布的指南,介绍了化学预防、阿育吠陀、顺势疗法和乌纳尼预防方法,以抗击COVID-19。这篇文章是基于印度阿尤什部发布的指导方针。提出的方法得到了科学证据的支持。文章还提供了一个展望全球情景的草药做法。在缺乏有效治疗的情况下,控制COVID-19大流行的努力严重依赖个人预防措施等非药物干预措施。替代医疗系统提供了简单而廉价的预防解决方案。这些简单的措施将在应对大流行病方面大有帮助。

The Dollar Value of Human Life Losses Associated With COVID-19 in Canada 加拿大与COVID-19相关的人员生命损失的美元价值
J. Kirigia, Rose Nabi Deborah Karimi Muthuri
Background: The coronavirus disease 2019 (COVID-19) pandemic continues to cause morbidity and premature mortality and ravage the socio-economic sectors in Canada.Objectives: The study aimed to appraise the Total Dollar Value of Human Life Losses (TDVHL) associated with COVID-19 in Canada. Methods: The net output approach was applied in the dollar valuation of the 8810 human life losses associated with COVID-19 in Canada as of July 16, 2020. The economic model wasrerun assuming 3%, 5%, and 10% discount rates with Canada’s life expectancy of 83 years, the world’s average life expectancy of 73 years, the world’s highest average life expectancy of88 years, and a 3% discount rate. Results: The human lives lost to COVID-19 had an estimated value of the international dollar (Int$) 2037021173 and an average of Int$ 231217 per human life lost. Quebec and Ontarioprovinces alone accounted for 94.99% of the TDVHL. Reanalysis of the economic model with discount rates of 5% and 10% resulted in declines in TDVHL of Int$ 192721390 (9%)and Int$ 530132423 (26%), respectively. Substitution of the nation with the word’s average life expectancy shrank the TDVHL by Int$ 1754972473 (86%) while applying the world’shighest life expectancy triggered a growth in the TDVHL of Int$ 498674987 (24%).
背景:2019冠状病毒病(COVID-19)大流行继续导致加拿大的发病率和过早死亡,并破坏了社会经济部门。目的:本研究旨在评估加拿大与COVID-19相关的人类生命损失总额(TDVHL)。方法:采用净产出法对截至2020年7月16日加拿大与COVID-19相关的8810人的生命损失进行美元估值。经济模型假设3%、5%和10%的折现率,加拿大的预期寿命为83岁,世界平均预期寿命为73岁,世界最高平均预期寿命为88岁,折现率为3%。结果:2019冠状病毒病死亡估计数为2037021173国际美元(Int$),平均每人死亡231217国际美元。仅魁北克省和安大略省就占了TDVHL的94.99%。重新分析贴现率为5%和10%的经济模型,TDVHL分别下降了192721390 Int$(9%)和530132423 Int$(26%)。以世界平均预期寿命代替国家,使TDVHL减少了1754972473美元(86%),而采用世界最高预期寿命则使TDVHL增加了498674987美元(24%)。

COVID-19 infection, a ravaging disease attributed to a SARS-CoV-like illness, has brought the world to its knee, causing a pandemic, with human-human transmission as a major source of the spread of this ailment. Alarmingly, this infection based on clinical manifestations is diagnosed as virus-induced pneumonia, with over 5 million cases with a mortality rate of about 7% (based on the recently published global report). However, most deaths have been associated with patients with underlying immune dysfunction or a compromised immunesystem. As no specific therapeutics and vaccines have been reported, the strengthening of the immune system through nutritional intake and exercise is essential. Also, previous studies have documented the immune-activating capabilities of Vitamin A and D, along with supplementary induction, yielding positive results in combating previous viral challenges. Typically, the gradual upsurge of T-lymphocytes and immune cell activities has been implemented by moderate exercise activities. This review examines the role of nutrition and exercise in immune system enhancement and proposes the possible mechanism of nutrition and exercise in combating COVID-19 infection.
COVID-19感染是一种由sars - cov样疾病引起的破坏性疾病,它使世界陷入瘫痪,引发了一场大流行,人际传播是这种疾病传播的主要来源。令人震惊的是,根据临床表现,这种感染被诊断为病毒引起的肺炎,有500多万例,死亡率约为7%(根据最近发表的全球报告)。然而,大多数死亡与潜在免疫功能障碍或免疫系统受损的患者有关。由于没有具体的治疗方法和疫苗被报道,通过营养摄入和锻炼来加强免疫系统是必不可少的。此外,先前的研究已经记录了维生素A和D的免疫激活能力,以及补充诱导,在对抗先前的病毒挑战方面产生了积极的结果。通常,t淋巴细胞和免疫细胞活性的逐渐高涨是通过适度的运动活动来实现的。本文综述了营养和运动在增强免疫系统中的作用,并提出了营养和运动在对抗COVID-19感染中的可能机制。
