Haemocytes play an essential role in defending invertebrates against pathogens and parasites that enter their haemocoel. A primary defense response is encapsulation; a process in which haemocytes attach to the foreign organism and kill it. Whether encapsulation requires cooperation between specific subpopulations of haemocytes is unknown. Using purified subpopulations of haemocytes and an in vi...

The aim of the present study was to determine various types of hemocytes, total and differential hemocyte count and to show some indices of phagocytosis, including percent phagocytosis and phagocytic index in Indian white shrimp, Fenneropenaeus indicus in Iranian shrimp farms. The hemolymph was extracted from the shrimps and mixed with anticoagulant. It then stained and Yeast was added as forei...

Granular cell tumors (granular cell rnyoblastoma) are neoplasms Which pursue a benign clinical course in large majority of cases. Tongue is the classic location for this tumor, however, rarely it is seen ill many other sites. Cases of granular cell tumor have been described in both male and female breasts The recognition of this entity in breast is important because it mimics breast carcinoma c...

BACKGROUND Granular cell tumor (GCT) is an uncommon benign tumor founded in any part of the body but mainly in the tongue. Extra-tongue oral granular cell tumor (ETOGCT) is rare with few cases reported. Here we describe seven cases of oral GCT located in sites other then the tongue and discuss histopathological and immunohistochemical differences between differential diagnoses. MATERIAL AND M...

INTRODUCTION A granular cell tumor involving the breast parenchyma was first described by Abrikossoff in 1931. Localization of this lesion to the breast is very rare, accounting for between 5% and 15% of all granular cell tumor cases. We present this case because of the rarity of this tumor. It is frequently confused with breast carcinoma on clinical and radiological examination, and its diagno...

We presented a 64-year-old male patient with T-large granular cell leukemia/lymphoma with an agressive clinical course. Large granular lymphocytes were noted on peripheral blood smear. The phenotyping of the cells was typical T-cell lineage [CD2 (+), CD3 (+), CD5 (+)]. Clonal rearrangement of the T-cell receptor gene (TCR) was demonstrated by DNA hybridization technique. Large granular cell leu...

the hippocampus showing the granular cell layer of the dentate gyrus (arrows) revealed by DTI contrasts at 160 Hz, which is not discernible at 0 Hz. Corresponding nissl-stained sections indicating the granular cell layer of the dentate gyrus (DG_gr) are shown for anatomical comparison. Bottom panel) Mean ADC in the DG_gr and a region within the CA1 subfield of the hippocampus plotted as a funct...

Ameloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not undergone differentiation to the point of hard tissue formation. Granular cell ameloblastoma is a rare condition, accounting for 3.5% of all ameloblastoma cases that shows marked transformation in the cytoplasm of tumor cells, which are usually stellate reticulum like cells. It is also con...

INTRODUCTION Congenital granular cell epulis is an uncommon tumor which is apparent at birth. CASE PRESENTATION Here we report an unusual case of congenital granular cell epulis present in the mouth of a 4-day-old Asian Chinese female newborn. She had six round, soft, multiple, pedunculated swelling masses, of which two were on her upper anterior ridge and four on her lower anterior ridge. Th...
