Abstract.Etching of enamel surfaces produces a marked increase in the bond strength of dental materials to tooth structure. The results of recent studies have indicated that pyruvic acid may be used in preference to phosphoric acid, because of its milder etching effect on enamel surfaces, without adversely affecting the bond strength. The pulpal responses elicited by 10 % pyruvic acid applied for 90 seconds to freshly prepared cavities in monkey teeth, were examined after 4, 14 and 42 days. The differences between some of the criteria used to evaluate the pulpal responses in acid‐treated and control teeth at the three postoperative time intervals were statistically significant. These results suggest that exposed dentin should be protected with a lining before etching adjacent enamel surfaces with 10 % pyruvic aci

摘要:

Abstract.The arterial blood pressure of 121 patients with oral lichen planus was determined using the auscultatory method. These values were then compared with those previously found in a general adult population. No significant difference was found between the values of the lichen planus patients and those of the general population. The present investigation does not support the hypothesis of a relationship between lichen planus and hypertension.

摘要:

Abstract.Of 123 patients with oral lichen planus two were known diabetics. The remainder were tested for fasting glucosuria, 113 for fasting blood glucose and 103 also with an oral glucose tolerance test. According to the criteria of WHO, 18 of the 123 patients were diabetics. In most of these patients the oral glucose tolerance test was only slightly abnormal. No decrease of the glucose tolerance with increasing duration of lichen planus was demonstrable. Comparison with two general population studies did not reveal any significant difference between the glucose tolerance of the lichen planus patients and that of the general population samples.

摘要:

Partial and full thickness flaps which were made in the facial gingiva of 10 dogs were reflected for 15 or 90 min. Specimens were examined histologically and biochemically from 3 to 28 days after initial surgery, The results indicate that flaps reflected for 15 min exhibited faster epithelial closure than those reflected for 90 min. Partial thickness flaps reflected for both 15 and 90 min showed less inflammation than full thickness flaps at 3 and 7 days post surgery and healed faster in respect to epithelial closure, mesenchymal healing, and bone regeneration. Biochemical analysis of the collagen concentration of the tissue flaps revealed similar collagen content in full and partial thickness flaps reflected for 15 min; however, the collagen concentration of partial thickness flaps opened for 90 min was higher than that in full thickness flaps.

摘要:

Abstract.The first step towards understanding the cellular interaction which results in autoimmune disease is to determine what triggers the recognition between a specific autoimmune antigen determinant and the cellular receptor. In this review, we have focused on the antigen inducing experimental allergic encephalitis (EAE) because the antigen has been characterized and a relatively large body of information on its biological activities has been accumulated. Clearly, a specific allergic encephalitis‐producing determinant is present and is represented on a relatively small portion of the molecule. The determinant induces a wide variety of biological reactivities, some of which are classed as cellular mediated. An attempt is made to dissect activities such as blast transformation (BT), migration inhibitory factor (MIF),in vivodelayed type hypersensitivity reaction (DTH) and EAE and to relate them to the structural requirements which the determinants possess. The complexities which arise indicate that subpopulations of cells with different receptor activities may respond selectively and that recognition of the receptor is produced by an EAE determinant consisting of three amino acids in a specific linear sequence. Furthermore, under experimental circumstances the EAE activity can be dissociated from the other activities (BT, MIF, DTH), indicating that while these tests are used generally to follow various human autoimmune disease activities, they may represent the reaction of a broad spectrum of cell
