In this study, we examined how the pulpal immune systems differ in children who suffer from hyperaemia and acute serous pulpitis. The Radial Immune Diffusion (RID) method was used to measure the IgA, IgG and IgM levels in pulpal blood in hyperaemia and acute serous pulpitis cases. The patient's own peripheral blood was used as the control group. The peripheral blood was taken with a capillary tube from the finger tip. The immunoglobulins and the Htc values of the blood were measured by the radial immune diffusion method. In our research, the immunoglobulin and hematocrit values of the blood (pulpal and peripheral) of 39 patients between the ages 6 to 13 years were measured. No significant difference was found between the IgA, IgG and IgM levels of pulpal and peripheral blood in hyperaemia and acute serous pulpitis cases. In the same patients, a significant difference was noted between the Htc values of the pulpal and peripheral blood.

在这项研究中，我们检查了患有充血和急性浆液性牙髓炎的儿童的牙髓免疫系统的差异。采用径向免疫扩散法(RID)测定充血和急性浆液性牙髓炎患者髓血中IgA、IgG和IgM水平。以患者自身外周血作为对照组。用毛细血管从指尖取外周血。采用径向免疫扩散法测定血清免疫球蛋白和Htc值。在我们的研究中，我们测量了39例6 - 13岁的患者血液(髓质和外周)的免疫球蛋白和红细胞压积值。充血和急性浆液性牙髓炎患者髓血和外周血IgA、IgG和IgM水平无显著差异。在同一患者中，髓血和外周血的Htc值有显著差异。

Laboratory studies have indicated that improvements in the physical properties of composite restorations, especially for posterior teeth, may be obtained if these materials underwent heat treatment prior to insertion. The purpose of this study was to compare the microleakage in Class II restorations ending on cementum/dentine when these preparations were restored by a direct placement composite resin as opposed to a direct inlay composite resin. Thirty-six human posterior mandibular teeth were used in this study and randomly divided into three equal groups; Group I was prepared and restored with the composite Ful-fil in a direct placement technique. Groups II and III were prepared and restored using a direct composite resin inlay technique. The material used in Group II was Brillant D.I.; that of Group III, Ful-ful. All preparations terminated 1.0 mm apical to the CEJ. The composite resin patterns of Groups II and III were oven-tempered before cementing with D.I. Duo Cement. Specimens were thermocycled 125 times between 5-55 C. Microleakage was noted cervically on a scale of 0 to 5. The composite Ful-fil, used as a direct placement material, exhibited less leakage (P less than 0.05) than either the Brillant D.I. composite or Ful-fil composite when these materials were placed as direct composite inlays.

实验室研究表明，复合修复体，特别是后牙，如果在植入前对这些材料进行热处理，可能会得到物理性能的改善。本研究的目的是比较直接放置复合树脂与直接嵌体复合树脂修复的II类修复体在牙骨质/牙本质上的微渗漏。本研究选用36颗人下颌后牙，随机分为3组;第一组采用直接放置技术制备和修复复合full -fil。采用直接复合树脂嵌体技术制备和修复II、III组。第二组使用的材料为brilliant D.I.;第三族，满的。所有制剂终止于CEJ顶端1.0 mm。在用D.I. Duo水泥固井之前，对第二类和第三类复合树脂模式进行了高温回火处理。样品在5-55℃之间热循环125次，颈部微渗漏在0到5级之间。作为直接嵌体材料，与Brillant D.I.或full -fil相比，该材料的泄漏量更小(P < 0.05)。

Non-enzymatic glycosylation of collagen and its relation to glycosylated haemoglobin in acute short-term diabetes. 急性短期糖尿病患者胶原蛋白非酶糖基化及其与糖化血红蛋白的关系。

Non-enzymatic glycosylation of collagen from rat-tail tendon was measured using the thiobarbitüric acid method in both normal and diabetic rats. Results were correlated with the glycosylated haemoglobin values. The non-enzymatic glycosylation of collagen increased in diabetics and showed a weak correlation with glycosylated haemoglobin (r = 0.735). Our findings showed that acute short-term diabetes can also cause an increase in non-enzymatic glycosylation of collagen and haemoglobin.

用硫代巴比妥三酸法测定了正常大鼠和糖尿病大鼠尾腱胶原蛋白的非酶糖基化。结果与糖化血红蛋白值相关。糖尿病患者胶原蛋白的非酶糖基化增加，与糖化血红蛋白呈弱相关性(r = 0.735)。我们的研究结果表明，急性短期糖尿病也可以导致胶原蛋白和血红蛋白的非酶糖基化增加。
