||4. Theoretical Meanings of Inflammation
Modern medical science explains that all diseases can be classified into three pathological changes: inflammation, degeneration, and tumorigenesis. Thus, recognizing theoretical meanings of inflammation will allow us to understand more closely what disease including cancer is.
(a) Pathological Change Related to Momentum
Theoretical analysis of inflammation enables us to indicate that inflammation is a pathological change related to momentum contained in a tissue. When a tissue raises the momentum, it causes inflammation. On the other hand, also when the background field of a tissue reduces the momentum, the tissue relatively raises the momentum; then, it causes inflammation. As seen in these indications, inflammation occurs to control the imbalance in momentum among tissues (organs).
(b) A Cell and Inflammation
A human body uses cellular function to neutralize the imbalance among organs. A cell is the smallest dynamic system in a human body, and can react as fast as possible to any changes a human body causes. In addition, a cell is a unit containing its own momentum, and can freely change its momentum with keeping its original-biological cellular character. Because of these mechanisms, a human body always, by using cellular function, causes inflammation when it loses good balance in momentum among the organs. In other words, a cell is the smallest dynamic system containing its own momentum, and plays a major role in allowing a human body to neutralize the imbalance in momentum among the organs as easy as possible. This must be the reason why a human body often causes inflammation.
||(d) Inflammation and Carcinogenesis
Importantly, medical science has explained that carcinogenesis occurs on the basis of inflammation. Two-stage carcinogenesis, which is one of the experimental carcinogeneses, teaches us clearly the close relationship between inflammation and carcinogenesis. Two-stage carcinogenesis occurs through two steps: initiation and promotion. Initiation is a step that a tissue is treated with a chemical substance named "Initiator"; promotion is a step that a tissue is treated with a chemical substance named "Promoter." In addition, medical science has explained that a promoter has the ability to cause inflammation in a tissue; furthermore, theoretical analysis of acute inflammation has concluded that when a tissue raises the momentum, it causes inflammation. For the reasons, it is indicated not only that promotion is a step that a tissue raises the momentum, but also that inflammation plays an important role in carcinogenesis.
