[Incidence of recurrent aphthae among children with gastrointestinal diseases]. / Chestota na ertsidivirashtite afti pri detsa sus stomashno-chrevni zaboliavaniia.

Recurrent aphthae is rather often disease during infantjuvenile age. The aphthous alterations on mucosa of the oral cavity could be of various etiology. They could be symptoms of a general aphthosis (recurrent aphthous stomatitis, Behçet's disease, Turen disease), an individual manifestation of allergic states, manifestation of immuno-deficiency states as well as secondary stomatitis during some general diseases. The present study presents information of the incidence of recurrent aphthae during various gastrointestinal diseases which progress with often alterations of oral cavity mucosa.

[Comparative studies on lactate, proteins and enzymes in saliva of healthy and periodontitis sick juveniles]. / Sravnitelni prouchvaniia za laktat, proteini i niakoi enzimi v sliunkata pri zdravi i parodontozno bolni iunoshi.

Total protein, lactate and enzyme activity of alkaline and acid phosphatase and lactate dehydrogenase were determined in mixed non-stimulated saliva of healthy and periodontitis sick patients, aged from 15 to 17. Enzyme determination, expressed in U/l was performed with ready tests of Boehringer; total protein in g%--according to Netelsson, lactate--in mg/100 ml. Increased activity of alkaline phosphatase was observed, depending on the inflammatory processes of periodontium. With acid phosphatase the discrepancies were more negligible but with a marked tendency to increased enzyme activity. The changes in lactate quantity were also indicative. No statistically significant differences were established for lactate dehydrogenase and total protein. Conclusions have been drawn for the practice.
