    On the impact of low concentrations of chlorophos in the period of early ontogenesis on digestive carbohydrases of underyearlings of roach Rutilus rutilus

    The remote effects of brief exposure to low doses of chlorophos (1 × 10−6 −1 × 10−2 mg/l) in the period of early ontogenesis of roach Rutilus rutilus have been studied. Diverse changes of the activity of carbohyd...

    Effect of ultralow concentrations of N-methyl-N′-nitro-N-nitrosoguanidine upon early development in roach (Rutilis rutilus): Intestine carbohydrase activities and kinetic characteristics of carbohydrate hydrolysis in the intestine of underyearlings

    The prolonged effects of short-term action of N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) in low concentrations 3 × 10−7 to 3 × 10−1 mg/l upon roach (Rutilus rutilus) early development have been studied. It was r...
