Abstract:
Morphologic and immunologic study were performed on the mucosa associated lymphoid tissue (MALT) of patients with allergic rhinitis. Scraping from 14 healthy subjects and 36 allergic ones were used. Besides ordinary hystological methods immunohistochemical ones wilk polyclonal antibodies were employed to study IgG, IgA, IgM, IgE and monoclonal antibodies used for B and T lymphocyte and subset T-suppressor cell identification. In a comparison between normal and allergic mucosa, the morphopathology show an accentuated edema and a slight fibrosis. Among the IgG, IgA and IgM do not show any substantial differences in the samples in normal or in allergic subjects; white traces of IgE are found in allergic patients, but are totally absent in normal ones. In the lymphocyte populations does not show any substantial changes between the two groups. Was also analyzed the mechanism and the majority of the factors by which were obtained the results.

Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
