結膜ならびに角膜に異常のみられたイヌ55頭、ネコ60頭から結膜スワブを採取、培養を行った。原因となる病原微生物の同定と、他の要因から原因を特定できるかについて検討を行った。その結果、イヌ、ネコともに眼異常と病原微生物、ならびにその他の要因との関係性を明らかにすることはできなかった。しかしながらEBM（Evidence Based ...Medicine）に基づいた治療を行っていく上で、結膜スワブ検査をはじめ、結膜掻爬試験等の実験室検査を行っていくことは必要であると考えられた。
In epidemiology and clinical research, the reproducibility of clinical parameters is most important. In this study, we examined the inter-and intra-examiner reliability of each of the following ...clinical parame -ters: plaque index (PH), gingival index (GI), probing depth (PD), attachment level (AL), and bleeding on probing (BOP). PD, AL, and BOP measurements were carried out with an electronic probe, The Florida Probe®. The measurements were performed on 17 subjects (5 patients and 12 healthy subjects). Clinical parameters were measured twice in each subject at intervals of 1-2 hours. For inter-examiner reliability, the first measurement was performed by one examiner and the second measurement by another examiner. For intra-examiner reliability, each measurement was performed on all subjects by one examiner. Interexaminer reliability of clinical parameters were 0.52 (PH), 0.52 (GI), 0.59 (BOP) (P1I, GI, BOP: Kraemer's Kappa), 0.73 (PD), 0.56 (AL) (PD, AL: correlation coefficient). Intra-examiner reliability of clinical parameters were 0.71 (PH), 0.66 (GI), 0.52 (BOP) (PH, GI, BOP: Kraemer's Kappa), 0.97 (PD), 0.94 (AL) (PD, AL: correlation coefficient). The results indicate that clinical parameters (PH, GI, PD, AL, BOP) can demonstrate good inter-and intra-examiner reliability. J. Jpn. Soc. Periodontol., 41: 144-152, 1999.
