تاثیر چندین روش تزریق هورمون GnRHa در تحریک و همزمانی اوولاسیون قزل آلای رنگین کمان (Oncorhynchus mykiss)
چکیده در این مطالعه اثرات آنالوگ هورمون آزاد کننده گنادوتروپین (GnRHa) بهشکل امولسیون آب در روغن(w/o) و خالص در تحریک و همزمانی اوولاسیون قزلآلای رنگین کمان بررسی شد. آنالوگ هورمون GnRH در محلول نمکی 9/0 درصد و یا گلیکول پروپلین حل شد و با حجم برابری از آدجوانت ناقص فروند (GnRHa-FIA)ترکیب گردید. در ماهیان تیمارهای مختلف 5/0 میلی لیتر از ترکیب مذکور تزریق شد. میزان هورمون در همه تیمارها به ج...
متن کاملFlow injection determination of xanthine oxidase inhibitory activity and its application to food samples.
The enzyme xanthine oxidase (XOD) has been recognized as a key enzyme causing oxidative injury to tissues by ischemia-reperfusion. For this reason, XOD inhibitor, which effectively suppresses this enzyme, plays an important role in the inhibition of many diseases related to reactive oxygen species (ROS). In order to screen XOD inhibitors rapidly and conveniently, a novel assay using flow inject...
متن کاملA four-wavelength channel absorbance detector with a light emitting diode-fiber optics assembly for simplifying the flow-injection analysis system.
A four-channel absorbance detector was developed for simplifying the flow-injection analysis (FIA). This detector used four light-emitting-diodes (LEDs) as light sources; their wavelengths were 470, 495, 590 and 635 nm, respectively. Their amplitudes were modulated electronically with different frequencies. The light emissions from them were merged by plastic-core fiber optics, and were detecte...
متن کاملMeasurement of porcine luteinizing hormone concentration in blood by time-resolved fluoroimmunoassay.
We validated a time-resolved fluoroimmunoassay (TR-FIA) using the lanthanide element europium as a non-radiological tracer for measuring luteinizing hormone (LH) in porcine peripheral blood. The dose-response curve of the reference standard ranged from 0.2048 to 50 ng/ml. Good parallelism was noted between the LH standard and plasma sample. The profile of LH throughout the estrous cycle, assess...
متن کاملFlow-injection assay of catalase activity.
A novel flow-injection assay (FIA) system with a double line for catalase activity was constructed in which an oxidase is immobilized and the substrate is continuously pumped to reduce the dissolved oxygen and to generate a given level of hydrogen peroxide. The catalase in a sample decomposed the hydrogen peroxide, and thus the increase in dissolved oxygen dependent on the activity was amperome...
