Scorpion venom toxicity is one of the major medical concerns from old years, due to its influence on human activities and health. From many years ago a lot of researches established to examine different aspects of venom toxicity and its effects on different organs. During these years researchers are doing more specific studies on the cytotoxicity of scorpion venom. In Iran, the yellow scorpion is one of the major threats based on its neuro toxicity and severe pathophysiologic effects and researchers tried to find the mechanism of these neuro toxic effects. The previous studies have shown that in isolated organs the yellow scorpion venom is affecting the ion channels. Also some studies showed that this venom has severe cytotoxic effects on the cell lines with many ion channels like nerve cell lines. In this study, the cytotoxic effect of the crude venom of on the 1321N1 cell line (cancerous nerve cells) was studied. Primary cell cultured investigated in the presence of different ion channel blockers: Ouabain (1mmol as Na channel blocker), Nifedipin (100 µmol as Ca channel blocker), and TEA (40 mmol as K channel blocker) by MTT method. The result showed that the crude venom has cytotoxic effect via Na channels.
蝎子毒液毒性多年来一直是主要的医学关注点之一,因为它会影响人类活动和健康。从多年前起,就开展了许多研究来考察毒液毒性的不同方面及其对不同器官的影响。这些年来,研究人员对蝎子毒液的细胞毒性进行了更具体的研究。在伊朗,黄蝎子因其神经毒性和严重的病理生理效应而成为主要威胁之一,研究人员试图找出这些神经毒性作用的机制。先前的研究表明,在离体器官中,黄蝎子毒液会影响离子通道。此外,一些研究表明,这种毒液对具有许多离子通道的细胞系(如神经细胞系)具有严重的细胞毒性作用。在本研究中,研究了黄蝎子粗毒液对1321N1细胞系(癌性神经细胞)的细胞毒性作用。通过MTT法在不同离子通道阻滞剂存在的情况下对原代细胞培养物进行了研究:哇巴因(1mmol作为钠通道阻滞剂)、硝苯地平(100µmol作为钙通道阻滞剂)和四乙铵(40mmol作为钾通道阻滞剂)。结果表明,粗毒液通过钠通道产生细胞毒性作用。
