Carbohydrate residues were localized in the glandular cells of the epidermis of Lumbricus terrestris by lectin histochemistry. The following biotinylated lectins were used: ConA, PNA, WGA, UEA-I. Each lectin has a specific binding pattern in the epidermal glandular cells. The ConA binding is evident in the orthochromatic mucous cells; PNA in the metachromatic mucous cells; WGA in the neuroendoc...

The concentration of toxic metals and polycyclic aromatic hydrocarbons (PAHs) in soil, their bioaccumulation Lumbricus terrestris areas around Kolo Creek, Niger Delta, Nigeria were evaluated this study. 12 soil samples collected from 4 sites, while also where obtained. Toxic extracted using aqua regia quantified with a flame atomic absorption spectrophotometer. Extraction PAHs was achieved by l...

Root growth through biopores is facilitated by low mechanical impedance and nutrient enrichment due to the deposition of organic material at biopore sheath. Plant roots earthworms impact sheath properties differently. However, literature lacks a quantitative study root distribution within pores, which were originated taproots or earthworms. According previous on pore connectivity, it can be hyp...

1. Measurements of electrical potential difference (PD), short-circuit current (SCC) and unidirectional fluxes of sodium and chloride were made across portions of the intestine. Based on the results, the intestine can be divided into at least four physiologically distinct regions. 2. These four physiological regions, designated from anterior to posterior as R I-II, R III A, R III B and R IV, do...
