An investigation of the phenotypic characteristics 19 rhizobial strains, isolated from root nodules different plant legumes grown in soil agriculture farms Ismailia governorate, transpired. Most isolates were creamy or white opaque, mucoid, with a convex elevation, translucent, and smooth margined. Microscopic revealed that all bacterial rod-shaped had no positive affinity for Gram-stain. Ident...

INTRODUCTION In some clinical situations such as when the Long Head of the Biceps (LHB) is unstable or with an "hourglass biceps", treatment is required. Tenodesis is an alternative to tenotomy to prevent the Popeye sign. Although sutures, anchors or interference screws may be used, they all have complications and drawbacks. Moreover, the number of failures is underestimated because it only con...

HeLa cells infected with herpes simplex virus have been examined in thin sections by electron microscopy after cytochemical staining for the presence of surface enzymes splitting adenosine triphosphate. As with uninfected HeLa cultures (18), the opaque enzyme reaction product was localized at the plasma membranes of about half the cells, tending to be present where there were microvilli and abs...

BACKGROUND Percutaneous central venous lines (long lines) are commonly used in neonatal practice. The position of these lines is important, because incorrect placement may be associated with complications. AIMS To determine whether the addition of radio-opaque contrast material improves the localisation of long line tips over plain radiography. METHODS Radiographs taken to identify long lin...

To the Editor: We read with great interest the report “Interference of Radio-opaque Agents in Clinical Capillary Zone Electrophoresis” (1 ). A laboratory sent two similar patient samples for our evaluation. Both patients had received intravenous sodium meglumine ioxitalamate (Telebrix), a radioopaque contrast material that absorbs at 214 nm. The interfering substance was not visible on agarose ...
