AIM: To evaluate the effect of mechanical periodontal treatment combined with tetracycline on per iodontal attachment level (AL) and the avidity of serum antibody against porphyromonas gingivalis( P. gingivalis) in patients with aggressive periodontitis(AgP). METHODS: Twenty- five patients with AgP and twenty periodontally healthy controls were studied (HS). Clinical examination and recordings of AL were performed before and 3,6 and 12 months after the periodontal treatment. The avidity of IgG antibody against P. gingivalis lipopolysaccharide(LPS) was measured by diethylamine dissociation ELISA. RESULTS: A significant improvement in AL was observed following treatment ( P ＜ 0. 01 ). The avidity of serum IgG antibody against P. gingivalis increased compared with controls, and was decreased significantly after mechanical periodontal treatment combined with tetracycline (P ＜ 0. 01 ). CONCLUSION: Ourresults demonstrate that mechanical periodontal treatment combined with tetracycline provides clinically favorable results in patients with AgP.

BACKGROUND: It has been proved that interleukin-18 (IL-18) involves in the development of acute cerebral infarction (ACI) and is positively correlated with the time of brain stroke onset, erythrocyte sedimentation rate (ESR), as well as neurological deficit and low-density value of brain CT.OBJECTIVE: To investigate the dynamic changes of serum IL-18 in the course of ACI.DESIGN: Verification analysis with patients as subjects and healthy volunteers as controls.SETTING: Department of neurology of a municipal hospital.PARTICIPANTS: Totally 46 inpatients (29 males and 17 females) with ACI were randomly selected from the Department of Neurology of People's Hospital, Maoming City, between December 2002 and January 2004.Meanwhile, 40 healthy controls (27 males and 13 females) were recruited from those who came to the hospital for routine physical examination. All the participants signed informed consent.METHODS: Fasting peripheral vein blood of 2 mL was collected from the patients on the 1st, 7rh, 14th and 21st days of ACI onset, and from healthy controls on the day of routine examination. The blood samples were centrifuged at 3 000 r/minute for 15 minutes at 4 ℃, and then the supernatant was collected for detecting IL-18 level by ELISA.MAIN OUTCOME MEASURES: The serum IL-18 level of patients on the 1st, 7th 14th and 21st days of ACI onset and that of healthy controls on the day of routine examination.RFSULTS: Totally 46 patients and 40 healthy controls were enrolled in this study and all data were statistically analyzed. The level of serum IL-18 was significantly higher in the patients with ACI than in normal controls on the 1st and 7th days of onset [(178±41) ng/L, (104±34) ng/L, (65±14) ng/L, P ＜ 0.01],but was similar on the 14th and 21st days [(88±36) ng/L, (72±33) ng/L,(65±14) ng/L, P＞ 0.05]. The level of serum IL-18 in ACI patients was significantly higher on the 1st day than on the 7th, 14th and 21 st days of the onset (P ＜ 0.05-0.01); moreover, it was also significantly higher on the 7th day than on the 21st day of the onset (P ＜ 0.05).CONCLUSION: The level of IL-18 increases obviously on the 1st day of ACI onset, and gradually decreases with the extended course of disease and time of treatment.
