[The alternation of peripheral lymphocyte subsets in head and neck carcinoma]
Abstract:
Peripheral lymphocyte subsets of 115 patients with head and neck carcinomas were examined by the monoclonal antibody technique. In fresh tumor-bearing, the OKT 4 rate was decreased (P less than 0.01) and the OKT 8 rate was increased (P less than 0.05). Consequently the OKT4/OKT8 ratio was decreased (P less than 0.01) compared with normal healthy individuals. This result shows the abnormality of cellular immunity in carcinoma cases. The OKT4/OKT8 ratio reflected the clinical stages and courses sufficiently and correlated with other immunological parameters. The OKT4/OKT8 ratio is considered to be one of the parameters for elucidating the clinical conditions and immunities of carcinoma patients.

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...
