저자는 Tetracycline의 전신적 혹은 국소적 투여가 백서에 견사결찰로 유발시킨 치주질환에 대하여 미치는 영향을 알기 위하여 다음과 같은 실험을 하였다. 50마리의 백서를 대조군과 4개의 실험군으로 각 각 10마리씩 나누어 제 Ⅰ군은 실험 개시 하루 전부터, 제 3군은 실험 개시일 부터 백서의 미정맥에 Tetracycline을 정맥 주사 하고, 제 2군은 실험개시 하루 전부터, 제4군은 실험 개시일 부터 Tetracycline을 국소 도포하였으며, 대조군과 모든 실험군에 실험 개시일 부터 상악 제 1대구치와 제 2대구치의 치간부에 4-0 굵기의 견사를 결찰하고 매일 약물을 투여하였으며, 실험 개시 후 1, 3, 5, 10, 20일째에 실험 동물을 실험군과 대조군 2마리씩 희생시켰으며, 실험 부위를 적출한 후, 7μ두께의 slide를 만들어 통법에 따라 Hematoxyline Eosin 중염색 및 Masson's trichrome염색을 하고 광학 현미경 하에서 400배로 다형핵 백혈구, 임파구, 형질 세포의 수를 세어 얻은 자료를 1-way ANOVA 방식과 Tukey 방식으로 통계 처리한 결과 다음과 같은 결론을 얻었다.

1. Tetracycline 국소 도포군(2, 4군)보다 정맥 주사군(1, 3군)에서 염증 세포의 출현이 적었다.

2. Tetracycline의 견사결찰 하루전 투여군(1, 2군)과 견사결찰 즉시 투여군(3, 4군)사이의 염증세포의 변화에는 큰 차이가 없었다.

3. 모든 실험군에서 PMNL은 3일 까지 증가하다가 5일 이후에는 차츰 감소하는 현상을보이며, 임파구는 5일 이후부터 완만하게 증가하였으며, 형질 세포는 변화가 거의 없었다.

4. Tetracycline 정맥 주사군(1, 3군 )에서는 실험 3일 이후부터 염증 세포들의 출현빈도에 큰 변화를 관찰할 수 없었다.

The purpose of this study was to observe the changes of the inflammatory cells after/with systemic and local tetracycline administrations in the rats whose gingivae were induced periodontal disease by the silk ligature.

In this experimental study, 50 rats were used and devided into one control and four experimental groups,10 rats for each group.

Tetracycline was daily administered systemically on tail vein to the Group 1 from the day before the experiment's beginning, and Group 3 from the day of its beginning, and daily applicated topically to the Group 2 from the day before its beginning, and Group 4 from the day of its beginning.

4-0 black silk were ligated to the 1st molar of all of the rats.

The rats were sacrificed on the 1st, 3rd, 5th, 10th and 20th day. The experimental areas were excised out and original slides were prepared with thickness of 7μm and stained with Hematoxyline-Eosin and Masson's trichrome. Inflammatory cells (polymorphonuclear cells, lymphocytes, and plasma cells) were

counted at a magnification of x 400 by light microscopy. The datas were treated by standard deviation, 1-way ANOVA and Tukey procedure.

The results were as follows.

1. In Group 1 and 3 (systemically administered tetracycline), inflammatory cells were less evident than in Group 2 and 4 (topically applicated).

2. There were no significant differences in changes of the inflammatory cells between Group 1 and 2 (tetracycline administered from the day before the experiment's beginning) and Group 3 and 4 (administered from the day of its beginning).

3. In all of the experimental groups, PMNLs were increased until the 3rd day and decreased from the 5th day, lymphocytes were increased slowly from the 5th day, and plasma cells did not changed significantly during the experiment.

4. In the Group 1 and 3 (systemically administered tetracycline), there were no significant variations in the number of inflammatory cells after the 3rd experimental day.
