This pattern indicates an increase in protein contents in the clitellum region, a decrease in head region and almost unaffected protein contents was found in the abdominal regions under the effects of imidacloprid on earthworms.
Effect of imidacloprid on the total protein contents in head, clitellum and abdominal region of earthworm Pheretima posthuma.
posthuma total protein contents was found to be 21.6 mg/ml in head region, 36.6 mg/ml in clitellum region and 30.90 mg/ml in abdominal region respectively (Table 3).
It has been demonstrated that, after being excited by about 660 nm excitation light, mice fed a normal animal diet show strong diet-induced fluorescence in the gastrointestinal (GI) track in the abdominal region, since chlorophyll from the alfalfa in commonly used laboratory rodent diets fluoresces between 665 and 750 nm [4].
In groups of mice fed an alfalfa-free diet, we observed no or minimal background in the gastrointestinal track (GIT) (abdominal region) of mice with Alexa-680 fluorescence imaging, whereas mice fed a regular diet showed high background fluorescence in the GIT (Figure 3 and Table 1).
