The capacity of a commercially available pool of bovine bone morphogenetic proteins (BMPs) to stimulate osteogenesis in the rat alveolar healing was investigated by histometric analysis. Male rats were anesthetized and had their upper incisor extracted. A pool of purified bovine BMPs adsorbed to microgranular resorbable hydroxyapatite was agglutinated with bovine collagen and saline before impl...

The purpose of this study was the clinical and histo-immunohistochemical analysis of two cases: a cutaneous pigmented facial malignant melanoma and a lumbar congenital nevus with malignant transformation. A series of clinical elements raised the suspicion of some malignant melanocytic lesions and the histopathological analysis through the paraffin embedding technique confirmed the clinical susp...

AIMS To describe histological findings in gastric mucosa biopsy specimens of children treated with proton-pump inhibitors (PPIs) for different periods of time. METHODS Biopsy specimens from 12 children (aged 8 months to 15 years) treated with PPIs and 8 controls were processed for paraffin embedding and stained with H&E as well as inmmunohistochemically for sialyl-Tn antigen. RESULTS The ma...

hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

background and objective: given the widespread use of paraffin in the treatment of constipation in chil-dren and the possibility of long duration of drug use and the risk of drug leakage, the risk of urinary infection in these patients is considerable. the aim of this study was to determine the association between leakage of paraf-fin and the presence or exacerbation of the urinary infection an...

Emphysema is characterized by enlargement of the alveoli, which is the most important parameter to assess the presence and severity of this disease. Alveolar enlargement is primarily defined on morphological criteria; therefore, characterization of this disease with morphological parameters is a prerequisite to study the pathogenesis. For this purpose, different methods of lung fixation were ev...

Introduction The standard approach to the diagnosis of acute leukaemia and myelodysplasia has been based on the morphology and percentage of malignant haemopoietic cells in peripheral blood and in an aspirated sample of bone marrow. The FAB group reports on acute leukaemia have emphasised the value of additional information gained from cytochemistry,' and immunological studies and cytogenetics ...

Cytologic material may contain cell clusters and tissue debris, which are often missed on smears. The processing in parallel of both cytologic smears and sediment when available has been recommended ,1-5 for tissue fragments present in the latter increase diagnostic precision. Paraffin embedding of the sediment for histological examination presents obvious technical difficultiesandit has been p...

Undecalcified bone histology demonstrates the micro-architecture of bone. It shows both the mineralised and cellular components of bone, which provides vital information on bone turnover or bone formation and resorption. This has tremendous importance in a variety of clinical and research applications. It yields beautiful images and allows for techniques such as fluorochrome assessment and hist...
