Panel A (3400 magnification hematoxylin and eosin) of the BM biopsy shows extensive sheets (90%) of immature large cells in a background of small lymphoid cells (arrow). Increased proerythroblasts (.25% in the touch preparation) with irregular nuclei, prominent nucleoli, and basophilic vacuolated cytoplasm were observed. Panel B demonstrates a Wright-Giemsa–stained marrow aspirate smear showing...

The periodic acid-thionin Schiff/potassium hydroxide/periodic acid-Schiff (PAT/KOH/PAS) procedure has been used to investigate the histochemical staining characteristics of the mucins found in adenocarcinoma and villous lesions of the large intestine. The 46 blocks examined represented 58 lesions from 37 patients, all of whom had had resections for carcinoma of the colon. tin sharp contrast to ...

It has been suggested that diffuse changes in epithelial mucins may help to identify a subgroup of patients with ulcerative colitis who are at increased risk of developing colorectal cancer. Colonoscopic biopsy specimens were taken from 11 colitic patients shortly before colectomies were performed, in which cancer was identified. These patients were matched to colitic patients without cancer fo...

IMPORTANCE In 1947, Sulzberger and colleagues published a micrograph of a blocked acrosyringium in a patient with atopic dermatitis (AD), believing that it had a large role in the disease process. Lacking appropriate probes, they could not confirm the finding. OBJECTIVE To confirm the observations by Sulzberger et al on the blockage of sweat ducts in AD in pathologic specimens. DESIGN AND S...

there are some reports about development of prenatal ruminants' testis. but there is not any report about it in goat; so the present study was performed on 23 goats fetuses collected from ahvaz slaughterhouse. after measuring fetuses crown rump length (crl), their approximate ages were determined. on the basis of the crl, the fetuses were divided into 6 groups. then testes were extruded ou...

A novel low-complexity dual-band memory polynomial (2D-LCMP) model for linearization of dual-band power amplifiers (PAs) is proposed in this paper. The in-band intermodulation (IM) and cross-band modulation (CM) distortion terms in the prior two-dimensional models have different impacts on the model performance. Therefore, they are considered respectively in the proposed model. Some redundant d...

By J. BURNS AND P. B. NEAME T lIE PERIODIC ACID-SCHIFF (PAS ) REACTION is generally accepted as the method of choice for demonstrating glycogen in blood cells. This reaction depends upon the presence, in glycogen, of vicinal glycols which are oxidized by periodic acid to dialdehydes. The latter are subsequently condensed with Schiff’s reagent to produce a magenta-red product, visible by light m...

The exact knowledge of the section thickness is a requisite for making the necessary corrections on DNA measurements in tissue sections. Several methods have been proposed to evaluate section thickness, each of them with advantages and disadvantages depending on the type of specimen and equipment available. We herein report another method based on preparation of standard material whose optical ...

Objective(s):The aim of this study was to investigate the effects of nutritional saffron (Crocus sativus L.) stigma hydroalcoholic extract on blood pressure (BP) and histology of the aorta in normotensive and hypertensive rats. Materials and Methods:   Saffron (200 mg/kg/day) was given orally for 5 weeks to normotensive and hypertensive rats. Hypertension was induced by NG-nitro-L-arginine meth...
