Adult Swiss albino male mice exposed to mercuric chloride via drinking water at 5 μg/ml for 100 days revealed significant reduction in the wet weight and severe histopathological changes in male accessory organs, poor level of serum testosterone and infertility. These effects were reduced remarkable and fertility was restored when drug (12.50 mg/mouse/day orally) was administered during mercury...

The pollen morphology of Pelargonium endlicherianum Fenzl. and Pelargonium quercetorum Agnew. from the family Geraniaceae was examined under light microscopy and scanning electron microscopy. Pollen morphologies are eurypalynous. The pollen grains were tricolporate, prolate-spheroidal and large. Aperture was ectoaperture, colpus was short, and the pores were oblate-spheroidal and large. The exi...

A tracheal aspirate from which parainfluenza 2 (PI-2) virus but not chlamydiae was isolated demonstrated positive immunofluorescence of elementary body- and reticulate body-like particles on direct examination with anti-chlamydia monoclonal antibodies (Syva Co.). In subsequent studies, we found this reagent to show specific staining of this strain of PI-2 as well as of 3 of 18 additional PI-2 s...

The genus Scleroderma contains gasteroid basidiomycetes, which form globose spores with echinulate to reticulate ornamentation on the surface. Based morphological observations in combination molecular data, four new species, S. erubescens, separatum, squamulosum, and vinaceum, were described from Yunnan, southwestern China. Images of fresh basidiomata scanning electron microscope (SEM) images b...
