Expression of VEGF and CD-31 in traumatic ulcer of diabetic Wistar rats after application of peel essential oil.

Objective: Diabetes mellitus (DM) is a metabolic disease that delays the healing process, including the interruption of the processes of angiogenesis and vasculogenesis. The etiology of most angiogenic-related diseases, such as diabetes complications, includes the presence of hypoxia caused by declined vascular endothelium growth factor (VEGF) and CD-31. d-limonene, one of the main constituents of , is considered to have angiogenic, antioxidant, hypoglycemic, and anti-inflammatory activities.

The Response of the Tongue Epithelial on Cigarette Smoke Exposure as a Risk Factor for Oral Cancer Development.

Objective:  The aim of this study is to analyze the tongue epithelial response to cigarette smoke exposure on a number of macrophages, lymphocytes, plasma cells, and matrix metalloproteinase 9 (MMP-9) expression to determine the risk factor of oral cancer development.

Materials And Methods:  Thirty will be exposed to two kinds of cigarette smoke by a smoking pump for 4 and 8 weeks. The tongues were collected to analyze the number of macrophages, lymphocytes, and plasma cells with hematoxylin-eosin.

Peel Essential Oil-Induced Type IV Hypersensitivity Reaction.

Background: Several studies have shown anti-inflammatory, anti-microbial, antifungal, and antioxidant effects from -peel essential oil (Cl-PEO). Cl-PEO can be developed as topical drugs for oral ulceration because of its potential active components. There have been no studies on the topical application of Cl-PEO inducing type IV hypersensitivity reaction.

Effects of topical application of propolis extract on fibroblast growth factor-2 and fibroblast expression in the traumatic ulcers of diabetic .

Background: A traumatic ulcer caused by diabetes mellitus (DM) is a lesion caused by an increase in advanced glycosylation end products (AGEs), which takes a long time to heal. AGEs cause angiogenesis, vasculogenesis and a decrease in leukocytes. Fibroblast proliferation and the number of glycosaminoglycans decline, thereby inhibiting the formation of granulation tissue, collagen deposition and platelet derivatives growth factor.
