| SALID | SAL_13084 |
| Biomarker name | Alpha-amylase 1 (EC 3.2.1.1) (1,4-alpha-D-glucan glucanohydrolase 1) (Salivary alpha-amylase) |
| Biomarker Type | NA |
| Sampling Method | Age 38-66, DMT2 and obese |
| Collection Method | Clinical healthy mucosa and no bone loss around the implants were recruited for the study |
| Analysis Method | Subjects were asked not to eat, smoke or drink (except water) for an overnight fast prior to collection of saliva samples. Their diets were similar with respect to protein content and uptake of fat and carbohydrates. Socioeconomical status was similar for both groups (survey data). |

| Title of study | A comparison of ghrelin, glucose, alpha-amylase and protein levels in saliva from diabetics |
| Abstract of study | During the past decade, many salivary parameters have been used to characterize disease states. Ghrelin (GAH) is recently-discovered peptide hormone secreted mainly from the stomach but also produced in a number of other tissues including salivary glands. The aim of this work was to examine the relationship between active (aGAH) and inactive (dGAH) ghrelin in the saliva and other salivary parameters in type II diabetic patients and healthy controls. Salivary parameters were assessed in a single measurement of unstimulated whole saliva from 20 obese and 20 non-obese type II diabetes patients, and in 22 healthy controls. Total protein and alpha-amylase were determined by colorimetric methods, and glucose by the glucose-oxidase method. Saliva aGAH and dGAH levels were measured using a commercial radioimmunoassay (RIA) kit. Salivary concentrations of aGAH and dGAH ghrelin were more markedly decreased in obese diabetic subjects than in the two other groups. Glucose and alpha-amylase levels were higher in diabetic subjects than in controls. Furthermore, there were correlations between GAH levels and BMI, and between GAH and blood pressure. However, there was no marked variability in saliva flow rates among the groups. These results indicate that measurement of salivary GAH and its relationship to other salivary parameters might help to provide insight into the role of ghrelin in diabetes. |
