With the increasing interest in the diagnosis of malignant cells in various exudates and body fluids, a method demonstrating certain nucleolar changes in considerable detail may be of value. I t is t he purpose of this paper to present such a method and to discuss briefly the nucleolar changes in benign and malignant tissues and also to point out the potential applicability of this method as an...

OBJECTIVES To investigate the relationship between the Helicobacter pylori (H. pylori) colonization and the grade of gastritis in the antrum and in the body of patients with duodenal ulcer (DU) or benign gastric ulcer (BGU). METHODS This study was performed in H. pylori-positive 220 DU patients and 180 BGU patients. H. pylori density was evaluated by modified Giemsa staining and CLO test, and...

BACKGROUND Prevalence of short segment Barrett's (SSB) oesophagus, defined as the absence of macroscopic Barrett's but histologically identifiable intestinal metaplasia, has been reported to be 18% based on haematoxylin and eosin (H&E) staining. AIMS To define the prevalence of SSB oesophagus using H&E and alcian blue staining and to determine whether SSB oesophagus is associated with inflamm...

In this study, detailed cytogenetic properties of the endemic Ak?ehir chub, Squalius recurvirostris, distributed in basin Ilg?n (Çavu?çu) Lake was investigated by applying standard Giemsa staining, C-banding and Ag-NOR technique. Diploid chromosome number is (2n) 50. A pair heteromorphic chromosomes detected karyotype females. However, difference not observed males. Therefore, it determined tha...

Howard, Dexter H. (University of California, Los Angeles). Intracellular behavior of Histoplasma capsulatum. J. Bacteriol. 87:33-38. 1964.-The tinctorial characteristics and intracellular generation time of Histoplasma capsulatum within mouse histiocytes maintained in tissue culture were studied. The appearance of viable and nonviable cells of H. capsulatum was observed after staining with the ...

Physical mapping of the 18S ribosomal RNA gene (rDNA) was carried out by fluorescent in situ hybridization (FISH) in the endangered freshwater fish O. belangeri. The specimens were collected from Imphal valley, Manipur, India and metaphase chromosome preparation was made using standard hypotonic treatment, methanol-acetic acid fixation and flame-drying technique followed by Giemsa, silver, CMA3...
