[Correction of phagocyte functional activity in inflammatory focus in patients with deep phlegmons of the neck]
High clotting activity (CA) of monocytes, low level of macrophage CA, and increase of proteolytic activity (PA) of neutrophils in the inflammatory focus predominate in patients with deep phlegmons of the neck at the peak of inflammatory process. Blood monocytes retain their anticlotting potential and macrophages possess CA during resolution of the inflammatory process. The neutrophil PA in the blood and lavage fluid was lower during the resolution phase in comparison with the peak of inflammation. Differentiated correction of phagocyte PA and LA in the inflammatory focus, predicted by laboratory findings, reduced the incidence of mediastinitis and improved the disease outcomes.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Chronic Inflammation: Introduction
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Immune Surveillance by NK Cells and Phagocytes
Natural Killer Cells: The Fast Responders
NK cells are large granular lymphocytes found in the blood and lymphatic system. These...
Inflammation
Cells of the Innate Immune Response
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
