The cellular content of amniotic fluid is primarily composed of desquamated squamous cells. Depending on their site of origin and maturation, the staining characteristics of the nuclei and cytoplasm differ. Prenatal foetal sex was determined by comparing the proportion of anucleate pyknotic nuclei to vesicular nuclei using Papanicolaou's stain and the proportion of red cells to blue cells using...

A method is described for the preparaproteins and glycoproteins. A minition of plasma membranes from human mum of 26 polypeptide bands were tonsil lymphocytes. The membrane identified with the Coomassie blue preparation has been characterized by stain. The glycoprotein material was electron microscopy and by the use distributed into at least five bands. of 5’-nucleotidase as an enzymatic Simila...

Greenhouse tests were conducted to determine the persistence of nonviable Heterodera glycines eggs in soil. Laboratory and greenhouse tests were conducted to determine the usefulness of the vital stains acridine orange and tetrazolium red for differentiating viable and nonviable eggs of H. glycines. Nonviable (boiled) egg preparations were compared with preparations that were not boiled for the...

A 53-year-old asymptomatic woman was found to have a pelvic mass at medical examination. Magnetic resonance (MR) imaging revealed a 4-cm solid mass at the right adnexal region, which showed marked hyperintensity on T(2)-weighted imaging and marked enhancement on post-contrast T(1)-weighted imaging. Chemical-shift imaging showed slight but significant signal loss on out-of-phase images, which su...

Port-wine stain is a vascular malformation characterized pathologically by ectasia of superficial dermal capillaris and clinically by persistent macular erythema. The association of a port-wine stain on a limb with soft tissue swelling, with or without bony overgrowth, is termed klippel-Trenaunay syndrome. Phakomatosis pigmento-vascularis is a combination of port-wine stain and cutaneous ...

Membrane fusion is an essential step during entry of enveloped viruses into cells. Conventional fusion assays typically report on a large number of fusion events, making it difficult to quantitatively analyze the sequence of the molecular steps involved. We have developed an in vitro, two-color fluorescence assay to monitor kinetics of single virus particles fusing with a target bilayer on an e...

Primary systemic amyloidosis is a rare entity. We report a case of primary systemic amyloidosis without any associated hematological abnormality who presented with macroglossia and hemorrhagic lesions around eyes and sub mammary region. There were soft lobulated masses around perianal region, labia majora and on external auditory meatus obstructing auditory canal. She was also operated for carp...

Adult lipid storage disorders with pulmonary involvement are rare and usually diagnosed at autopsy. We report a patient with splenomegaly and reticulonodular pattern on lung computed tomography. Bronchoalveolar lavage was performed and revealed the presence of lipid-containing foamy cells, with the demonstration of both periodic acid-Schiff (PAS) and scharlach red stain positive vacuoles in the...

Fig. 1. Dry gangrene of the fingers (A and B) and dusky red discoloration of the right great toe (C) are shown. Progression of the gangrene of the fingers (D and E) and development of gangrenous necrosis of the toes (F) are shown. Plain radiographs demonstrating marked vascular calcification of the hands and feet (G–J). Skin biopsy revealing calcification (K) and microthrombosis (L and M) of sm...
