For the present study, and follow-up of histochemical changes in estradiol valerate-induced polycysticovary syndrome (PCOS), 48 virgin 90-day-old female rats were used. The rats were divided into thetreatment and control groups. For each rat of the treatment group, 4 mg estradiol valerate was injectedthrough intramuscular route for the induction of PCOS. The control group was taken the same amo...

The aim of this study was an application of spatial visualization techniques for quantitative measurements of immuno- and histochemical reactions. For a quantitative histochemical study, specimens, collected from patients with chronic gastritis, were stained with paS/AB, while for immunohistochemical evaluation, specimens were used, collected from patients with chronic parathyroiditis and were ...

The routine study of bone marrow trephine biopsies involves fixation, decalcification, paraffin-embedment, sectioning and staining. However, this process creates artifacts, produces shrinkage of tissue, consumes time and can result in sections of unsatisfactory cytological quality. It also renders the tissue unsuitable for enzyme-histochemical and immunohistochemical analyses. Frozen section of...

The morphological and histochemical changes in muscle biopsies from 6 cases with myasthenia gravis (MG) were studied, The patients were misdiagnosed at the initial presentation, however they were all proved later by either histochmical and serological tests or improvement on mestinone therapy to have MG. Here, the histomorphological and histochemical changes that were seen in muscle biopsies of...
