Response to Morphine in a unicellular animal model (Paramecium caudatum)
Introduction: Response to morphine and role of Nitric Oxide (NO) on expression of morphine response has been studied in vertebrates. But, little evidence is provided in the matter in earlier invertebrates. This investigation for the first time evaluated the effect of NO on expression of morphine potency in Paramecium caudatum. Methods: Animal after isolation from natural media and specific i...
متن کاملAcute Toxicity and Cytogenetic Effects of Monocrotophos in Paramecium Caudatum and Oxytricha Fallax
In the present study experiments were conducted to evaluate the toxic effects of monocrotophos on ciliate models Paramecium caudatum and Oxytricha fallax, which can be considered as ideal organisms for investigating water quality fluctuations and risk assessment of pesticides. Cell viability, cell morphology, cell behaviour and macronucleus tests were performed using to different concentrations...
متن کاملتأثیر دما و عوامل معدنی و آلی بر رشد و تکثیر Paramecium caudatum در محیط کشت مخمر
تک یاختگان مژه دار مانند Paramecium caudatum را می توان در محیط کشت مخمر پرورش داد. در این پژوهش تأثیر دما و غنی سازی محیط کشت مخمر بر رشد و تکثیر جمعیت P. caudatum بررسی شد. رشد جمعیت P. caudatum در محیط کشت مخمر تحت دماهای مختلف (40-20 درجه سانتی گراد) و تحت غنی سازی با یونهای Ca2+ وMg2+ و اسید آمینه ال-آرژینین مورد مقایسه قرار گرفت. طبق نتایج، جمعیت این جانوران 48 ساعت پس از پاساژ در دمای 3...
متن کاملA study on the toxicity of natural food dyes--toxicity and enzyme inhibition in Paramecium caudatum.
The toxicity of 14 commercial natural dyes which are widely used as food additives in Japan was studied on Paramecium caudatum. Laccaic acid and capsanthin were found to be very toxic to Paramecium caudatum. Some of the commercially available carminic acid and crocin were also toxic. The inhibitory effect of natural food dyes on leucine aminopeptidase, acid phosphatase and esterase in vitro was...
متن کاملCytotoxicity assessment of monocrotophos in Paramecium caudatum and Oxytricha fallax.
Experiments were conducted to evaluate the toxic effects ofmonocrotophos in ciliate models Paramecium caudatum and Oxytricha fallax. In acute toxicity studies higherconcentrations of monocrotophos caused marked increase in mobility of cells exhibiting rocking movements within two mins of exposure but were decreased after 30 mins. LC50 value by mortality curve for 3 hr acute toxicity test of Oxy...
