"Background: Diabetes Mellitus is a chronic disease characterised by elevated levels of blood glucose known ashyperglycaemia. Diabetes is due to impaired insulin action in the metabolism of glucose and can result in impairedwound healing. Excessive production of pro-inflammatory cytokines, an increased number of macrophages andneutrophils, and decreased levels of transforming growth factor ? beta 1 (TGF-β1) serum can be characteristic ofimpaired wound healing. This study aims to determine the effects of squid extract on certain wound parameters such aslevels of tumour necrosis factor ? alpha (TNF-α), and TGF-β1 serum and the number of macrophages and neutrophils.Methods: This was a post-test only, randomized controlled group study that was conducted on male Wistar rats.Experimental animals were divided into 6 groups; (1) normal wound with standard diet, (2) diabetic wound withstandard diet, (3) diabetic wound with chitosan supplement, (4) diabetic wound given squid extract orally once a day,(5) diabetic wound given squid extract orally twice a day, and (6) diabetic wound given squid extract orally once everytwo days. Levels of TNF-α and TGF-β1 serum were observed using Enzyme-Linked Immunosorbent Assay.Haematocylin and eosin staining was used to observed macrophage and neutrophil counts. All data was analysedstatistically by one-way analysis of variance. Results: TNF-α serum levels showed a significant decrease (p < 0.05) insubjects that received squid extract orally once every two days. The mean levels of TGF-β1 showed no significantdifferences. The mean number of macrophage cells showed a significant decrease (p < 0.05) in all treatment groups.The mean number of neutrophil cells also showed significant decrease (p < 0.05) in all treatment groups. Conclusions:Squid extract is effective in lowering the TNF-α serum levels and the number of macrophages and neutrophils cells inWistar rats. However, there were insignificant findings on increasing levels of TGF-β1 serum. This data suggests thatsquid extract is most effective during the inflammatory phase of wound healing which takes places about 2-4 days afterwound creation."

"Periodontal status is a periodontum condition evaluated by using plaque index, calculus index, gingival index and pocket index. The main mediator of periodontum inflammation is IL-113 examined by ELISA method. There is an evaluation of PMN s in periodontum inflammation, but the leucotoxin as well as the protease in turn lowers the PMN phagocytotic function. Phagocytotic function was measured by flowcytometry. The aim of the study was to evaluate the high risk factors of being type 2 DM. A diagnostic study was conducted by using cross-sectional design on 45 controlled DM (CDM) subjects, 45 uncontrolled DM (UCDM) subjects in the Metabolic Endocrinology Clinic Cipto Mangunkusumo Hospital Jakarta, as compared to 45 non-DM control subjects. The result of multivariate analysis showed that patients of older age (>54 years old), low periodontum status (periodontal index >1.80), high IL-113 level (>23.70 pg/mL), and low PMN phagocytotic function <<53.47%), were significantly at high risk of having DM compared to non-DM (p<0.05). Lower periodontum status showed an increase in IL-113 level, decrease PMN phagocytotic function, and consequently, an increase in the risk of being type 2 DM."
