In a broad sense, inflammatory reactions comprise a sequence of events such as acute and chronic inflammations, granulation tissue generation, foreign body reaction, and fibrous encapsulation (or fibrosis). Depending on the implantation process and material...

Blood-biomaterial interactions, provisional matrix formation, acute and chronic inflammation, granulation tissue development, foreign body reaction, and fibrosis/ fibrous capsule development comprise the series of host reactions occurring after device implantation (Fig. 4.3b) [3]. 

Fig. 9.6 Histology of 220-CNTs and 825-CNTs implanted in the subcutaneous tissue. 1 week Clusters of both of 220-CNTs and 825-CNTs were surrounded by granulation tissue, (a) Many of the 220-CNTs were enveloped by macrophages (arrows), (b) Some of the 825-CNTs were observed in the intercellular space (arrows), while others were observed in macrophages (white arrows), 4 weeks (c) Most of the 220-CNTs were observed in macrophages (arrows) and fibroblasts (white arrows), (d) There was a negligible difference in the degree of inflammation around 825-CNTs 4 weeks following surgery, compared to 1 week. All scale bars are 10mm (Gong et ah, 2000. With permission from The Royal Society of Chemistry)...

Thus it seems that hyperglycaemia can inhibit inflammatory reactions in which hypersensitivity or anaphylactoid-type states are involved, but not, apparently, inflammation produced compound 48/80 or bradykinin . The inhibition of granulation tissue by hyperglycaemia also cannot be explained by the Adamkiewicz hypothesis. That hyperglycaemia can affect certain types of inflammation is not in question, but its role and its limitations have yet to be clarified.

Flavonoids such as baicalein from Scutellaria baicalensis and S. lateriflora inhibit pro-inflammatory metabolites including certain prostaglandins and leukotrienes. Quercetin and others are effective inhibitors of the release of histamine induced by various agents. They inhibit a number of stages of inflammation including granulation tissue formation in chronic arthritis (Middleton and Drzewiecki... 

The tissue which borders the implant reacts with dynamic processes which are comparable to body reactions in cases of injuries or infections. Due to mechanical and chemical stimuli the implant can lead to a lasting stimulus of inflammation processes. As a consequence a granulated tissue is formed around the implant which beside inflanunation cells contains collagen fibrils and... 

Polypoid filling defects and enhancing mucosal soft tissue at colonic anastomosis are nonspecific findings on CT colonography in patients with a history of colorectal cancer and can represent granulation tissue, inflammation or recurrent or metachronous disease. 

HP is an airway-centered ILD that may be acute or chronic. Acute HP is a type III hypersensitivity reaction, and chronic HP is a type IV hypersensitivity reaction. In both cases, the antigen is introduced to the lung through the airways and results in airway inflammation of some degree (23). Bronchioles may show features of constrictive bronchiolitis with subepithelial granulation tissue and fibrosis however, complete luminal obliteration is not seen. As the disease progresses, peribronchiolar metaplasia develops via the canals of Lambert, also called Lambertosis (24).
