introduction: there is no single test as a gold standard for the diagnosis of allergic rhinitis (ar). the aim of this study was to assess the usefulness and validity of nasal smear as a quick, easy and inexpensive diagnostic method for diagnosis of allergic rhinitis. materials and methods: this study was conducted in a university hospital setting. nasal smears were taken from 39 patients with a...

Microscopic examination of a peripheral blood smear revealed ookinetes of Plasmodium vivax. This unusual finding was probably due to an excessive delay between blood collection and smear preparation. Ookinete formation normally occurs in the mosquito gut. When seen in blood smears, it can cause confusion and misidentification of the parasite.

The finding of large granular cells is relatively frequent when reviewing a blood smear for lymphocytosis (or any other reason). presence these opens the question as if they are part T-cell non-clonal reactive process or indicate clonal population (yet not necessarily neoplastic).

Processed antigen reacts selectively with lymphocytes bearing .appropriate surface immunoglobulin molecules resulting in the clonal proliferation of these cells, produc­ing circulating immunoglobulin (humoral immunity) or non-circulating immunoglobulins (cellular immunity).  High levels of circulating immunoglobulins (lgM & lgG) occur in protozoa and helminths infections. Reaginic antibodies a...

leishmaniasis is one of the major health problems and categorized as a class i disease (emerging and uncontrolled) by world health organization (who), causing highly significant morbidity and mortality. indeed, more than 350 million individuals are at risk of leishmania infection, and about 1.6 million new cases occur causing more than 50 thousands death annually. because of the severe toxicity...

Immunity in the infant has been extensively studied in the past and numerous investigations have been made into the development of specific immunity, the production of antibody and the passive transfer of antibody from the mother. On the other hand comparatively little work has been devoted to elucidating the complexities of the cellular response since Tunnicliff (1910) observed that phagocytos...
