gingivitis/proline

Sensitive fluorogenic assays were used to compare the protease activities of fluid collected from eight such sites in each of 21 adult patients with gingivitis and 22 with periodontitis. The degradation of N-carbobenzoxy-gly-gly-arginine-AMC, L-arginine-AMC, glyproline-AMC, L-leucine-AMC,

BACKGROUND Gingival overgrowth occurs in patients receiving nifedipine. Gingival inflammation may be an etiologic factor. METHODS Gingival fibroblasts were either exposed to (i) 0-500 ng/ml TNF-alpha or 10(-7) M nifedipine or (ii) 0-500 ng/ml TNF-alpha + 10(-7) M nifedipine for 7 days. 3H-proline

The present study was performed to investigate the effects of endotoxins from periodontopathic bacteria on collagen metabolism. Endotoxins were extracted from Bacteroides gingivalis 381 and Bacteroides intermedius ATCC 25611 using the hot-phenol method. A commercially available endotoxin from

Progress in characterizing the receptors that promote bacterial attachment to teeth and oral epithelial cells has suggested that hidden molecular segments may frequently be involved. Such cryptic receptors, referred to as 'cryptitopes', may become exposed by several mechanisms. Hidden segments of

BACKGROUND In attempts to elucidate factors stimulating bone resorption in patients with different inflammatory diseases in the vicinity of the skeleton, e.g., peridontal disease and rheumatoid arthritis, we are investigating the presence of bone-resorbing activity in a variety of inflammatory

The ability of Bacteroides gingivalis 381 to attach to hydroxyapatite (HA) beads, treated with either human type I or type IV collagen, or to particles of bovine bone collagen was studied. All preparations were blocked with human albumin prior to being incubated with 3H-thymidine-labeled B.

Nowadays there is increasing interest in identifying-and using-metabolites that can be employed as biomarkers for diagnosing, treating and monitoring diseases. Saliva and NMR have been widely used for this purpose as they are fast and inexpensive methods. This case-control study aimed to find

Campylobacter rectus is an important periodontal pathogen in humans. A surface-layer (S-layer) protein and a cytotoxic activity have been characterized and are thought to be its major virulence factors. The cytotoxic activity was suggested to be due to a pore-forming protein toxin belonging to the

Tricyclic antidepressants are still a dominating group of psychotherapeutic drugs used in the treatment of depression. Oral dryness is one of their major side-effects, leading in humans to increased oral disease and dysfunction of speech, chewing, swallowing and taste. We previously reported that

Cyclic antidepressants are still a dominating group of psychotherapeutic drugs used in the treatment of depression. One of their major side effect is salivary gland dysfunction (oral dryness, xerostomia), leading in humans to increased oral disease and dysfunction of speech, chewing, swallowing and
