Abstract Background The aim of this study was to compare the performance new flow cytometer UF-5000 with UF-1000i and Gram staining for determining bacterial patterns in urine samples. Methods Women who attended our clinic symptoms suggestive urinary tract infection were enrolled study. Mid-stream samples collected gram staining, analysis cultures. Bacterial classified using (none, cocci bacter...

Sucrose-gradient-purified dictyosomes of plant Golgi apparatus appear, after glutaraldehyde stabilization, as stacks of highly fenestrate and tubate cisternae when negatively stained with phosphotungstic acid, shadowed with heavy metal, or OsO(4)-stained in thin section. The tubular proliferations (diameter 200 to 400 A) extend for several microns from the central region and are united at inter...

The virus host-cell relationship has been studied in the electron microscope almost entirely by the thin sectioning technique. This method has given information about the sites of virus production within the cell and the appearance of virus particles at various stages in the growth cycle (1, 2). I t does not, however, permit high resolution studies on the substructure of individual particles or...

A 36-year-old woman was diagnosed with a sellar-suprasellar craniopharyngioma and underwent transsphenoidal resection of the tumor. A lumbar drain was placed to minimize intracranial pressure and was removed on postoperative day 6. On postoperative day 9, the patient began to leak cerebrospinal fluid (CSF) from her right nostril. A second lumbar drain was placed. One day later, the patient deve...
