The relationship between c-erbB-2 gene expression (assessed immunohistochemically), S-phase fraction (SPF) and prognosis has been analysed in 172 women with primary breast cancer. c-erbB-2 staining was independent of age, tumour size, number of nodes involved, tumour grade and DNA ploidy, but was more common in oestrogen receptor (ER) negative tumours (P = 0.02) and progesterone receptor (PgR) ...

BACKGROUND Electron tomographic analysis can be combined with the simple and rapid negative staining technique used in electron microscopy based virus diagnosis. METHODS Standard negative staining of representative examples of parapoxviruses and paramyxoviruses was combined with electron tomographic analysis. RESULTS Digital sectioning of reconstructions of these viruses at a selected heigh...

Objective. To examine whether Gram staining can influence the choice of antibiotic for the treatment of peritonsillar abscess. Methods. Between 2005 and 2009, a total of 57 cases of peritonsillar abscess were analyzed with regard to cultured bacteria and Gram staining. Results. Only aerobes were cultured in 16% of cases, and only anaerobes were cultured in 51% of cases. Mixed growth of aerobes ...

background: chromomycin a3 (cma3) staining has been used to assess protamine deficiency. the aim of this study was to determine credibility of cma3 along with semen parameters for assessment of fertility potential. materials and methods: semen analysis and cma3 staining were carried out on 234 fertile and 178 subfertile individuals. semen analysis was assessed according to who criteria. protami...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

One hundred and forty two patients (62 with definite Sjögren's syndrome, 24 with probable Sjögren's syndrome, and 56 in whom Sjögren's syndrome was finally ruled out) were studied. Schirmer's test and rose bengal staining for the diagnosis of keratoconjunctivitis sicca and salivary scintigraphy and a labial biopsy sample for the diagnosis of xerostomaia were studied in all patients. Rose bengal...

Although there are criteria for interpretation of the staining results for Her-2/neu in the DAKO HercepTest, the determination of staining intensity and percentage of complete membrane staining is subjective. We studied 46 cases of invasive breast carcinoma to evaluate interobserver reproducibility among 5 pathologists. Complete agreement was achieved in 22 (48%) of46 cases. Generalized kappa v...
