REGULATION OF ANTIOXIDANT ENZYMES IN PATIENTS AFTER PERIODONTAL TREATMENT WITH NATURAL AGENTS.

Objective: The aim: The study of the possibilities of oxidase-antioxidant system indicators regulation at patients with periodontitis under the influence of complex treatment.

Patients And Methods: Materials and methods: 36 healthy and 125 patients with chronic and exacerbated periodontitis of primary (22 and 21), I (21) and II (20) degrees were examined.Indicators of lipid peroxidation and antioxidant protection (levels of diene conjugates and malonic dialdehyde, catalase activity and transferrin iron saturation, ceruloplasmin activity) in the blood serum were studied before, 6 and 12 months after the appointed treatment.

Reasons for testing women for genital Chlamydia trachomatis infection in the Calgary region.

Objective: To determine the clinical reason(s) for screening women with varying degrees of risk for genital Chlamydia trachomatis (CT) in the Calgary region.

Design: Women aged 15 to 75 years were enrolled at various patient care locations. Pertinent risk factors for genital CT infection were recorded and a gynecological examination was performed.

Evaluation of BBL CHROMagar O157 versus sorbitol-MacConkey medium for routine detection of Escherichia coli O157 in a centralized regional clinical microbiology laboratory.

The performance of BBL CHROMagar O157 (CHROM) versus that of sorbitol-MacConkey (SMAC) media for detection of Escherichia coli O157 was determined for a 3-month period. Results for 27/3,116 (0.9%) stool cultures were positive.

Selective testing of women based on age for genital Chlamydia trachomatis and Neisseria gonorrhoeae infection in a centralized regional microbiology laboratory.

Calgary Laboratory Services, Alberta, Canada, provides microbiology services via a centralized laboratory to the Calgary Health Region. A selective genital Chlamydia trachomatis (CT)/Neisseria gonorrhoeae (GC) testing policy for women >35 years was implemented. The changes in physician ordering practice, the rate of detection of infections, and the test turnaround times were monitored.

Screening for Giardia/Cryptosporidium infections using an enzyme immunoassay in a centralized regional microbiology laboratory.

Context: Stool parasitologic testing for Giardia and Cryptosporidium (G/C) previously relied on staining (ie, modified iron hematoxylin-kinyoun), ethyl acetate concentration procedures, and microscopy (the stool ova and parasite method). In April 1999, a microplate enzyme immunoassay (EIA) (ProSpecT G/C, Remel, Inc, Lenexa, Kan) for routine screening of all stool specimens was implemented.

Objective: To determine the clinical and laboratory impact of this service change.
