This study was conducted for determination of antibacterial effect of Echinometra mathaei extraction on human disease bacteria. Samples were collected in Abu Mosa Island. Extraction operation was done by shell, spines, gonad and aristotle's lantern. Ethyl acetate, n-hexane and methanol were used for extraction operation respectively. Extraction effect of these organs was investigated on Vibrio ...
چکیده مقدمه: توتیاهای دریایی به شاخه خارپوستان (echinodermata) از بی مهرگان دریایی تعلق دارند که دارای خواص زیستی متعددی می باشد. دیابت شیرین، شایع ترین بیماری متابولیک در جهان است که شامل گروهی از اختلالات متابولیسمی با درجات متفاوت می باشد و اولین مشخصه آن افزایش سطح گلوکز در خون است. هدف از مطالعه پیش رو، بررسی خاصیت ضددیابتی به روش ارزیابی مهار فعالیت آنزیم آلفاآمیلاز توسط ارگان های مختلف، ...
Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos were placed ...
species identification is always important. records of sea urchins and sand dollars species (echinodermata, echinoidea) is given from iranian waters. nine species of echinoderms were identified through the study. the species identification was made using morphological characteristics and review of checklist key. nine species were identified here, including echinometra mathaei, prionocidari...
