Matrix metalloproteinases (MMPs), especially collagenase-2 (MMP-8), are key mediators of irreversible tissue destruction associated with periodontitis and peri-implantitis. MMP-8 is known to exist in elevated amounts and in active form in the gingival crevicular fluid (GCF) and peri-implant sulcular fluid (PISF) from progressing periodontitis and(More)
BACKGROUND A rapid chair-side test based on the immunological detection of elevated levels of collagenase-2 (matrix metalloproteinase-8, MMP-8) in gingival crevicular fluid (GCF) was developed to identify and monitor the course and treatment of adult periodontitis. METHODS MMP-8 was determined in GCF from periodontitis (11 patients, 90 sites), gingivitis(More)
BACKGROUND AND OBJECTIVE With current periodontal diagnostic tools it is difficult to identify susceptible individuals or sites at risk. The aim of this study was to evaluate the efficacy of the matrix metalloproteinase (MMP)-8-specific chair-side dip-stick test in longitudinally monitoring the periodontal status of smoking (S) and nonsmoking (NS) patients(More)
BACKGROUND A simple, rapid test is specific and sensitive enough to distinguish, in patients with clinically suspected acute pancreatitis, those whose abdominal pain is indeed of pancreatic origin has proved elusive. METHODS In two consecutive series of surgical patients in a teaching hospital, whose acute abdominal pain turned out to be due to acute(More)
OBJECTIVES The aim of this study was to investigate the effect of scaling and root planing (SRP) and the maintenance phase of treatment on the gingival crevicular fluid (GCF) matrix metalloproteinase-8 (MMP-8) levels. MATERIALS AND METHODS Clinical measurements and GCF samples were taken from four sites in 20 adult periodontitis patients before and after(More)
The serum concentration of the new tumor marker MCA (mucinous carcinoma associated antigen) was determined by an enzyme immunoassay kit method, which is based on the use of a monoclonal antibody b12. The mean MCA values in breast cancer patients (n = 40) were significantly higher than in patients with benign breast disease (n = 55, p less than 0.001) and in(More)
We determined free triiodothyronine (FT3) and free thyroxin (FT4) in serum of patients with various nonthyroidal illnesses (NTI), by both commercial analog-type radioimmunoassays (A) and new equilibrium dialysis procedures (D). The mean FT3 was significantly lower in NTI by both techniques, but the decreases were of different magnitudes. The FT3(D):FT3(A)(More)
The levels of lysozyme (LZM) and beta 2-microglobulin (beta 2m) were measured in the cerebrospinal fluid (CSF) and serum of 32 patients with sarcoidosis, 20 of whom had neurosarcoidosis. LZM was analyzed by a new radioimmunoassay (RIA) modification. CSF LZM was elevated in 15 of 20 patients with neurosarcoidosis but in only 4 of 12 patients with extraneural(More)
The urinary neopterin index (U-NEOPT-I), expressed as micro-moles of neopterin/moles of creatinine) of 67 patients with definite or classical rheumatoid arthritis was significantly higher than that of sex- and age-matched persons or of 24 non-matched patients suffering from osteoarthrosis or arthralgia (2p less than 0.001). Furthermore, the patients with(More)
Elevation in the total sialic acid (TSA), TSA/total protein (TSA/TP) and lipid-bound sialic acid (LASA) concentration in serum occurs in breast cancer and we have studied the applicability of the assays in classification of undefined breast tumors. Sialic acid was determined by HPLC and the statistical evaluation included the receiver operating(More)
