ABSTRACT
Introduction: Florid osseous dysplasia (FOD) has been described as a reactive fibro-osseous lesion affecting the jaw bones especially the tooth bearing areas. Usually, this lesion is asymptomatic unless accidentally detected during radiographic examination for any other purpose. Although the etiology is unclear, several theories suggests that its origin was related to reactive or dysplastic changes within the periodontal ligament. Case Presentation: Presenting a case of Florid Osseous Dysplasia within the edentulous maxilla and mandible of 65-year-old female patient. Patient reported with a diffuse swelling in the edentulous maxillary and mandibular posterior regions intraorally. Radiographically, multiple radiopaque lesions were noted bilaterally in the posterior mandible and also in the right posterior side of the maxilla. On microscopic examination, the lesion was composed of spicules of bony trabeculae with osteocytes in lacunae and intervening fibro-fatty connective tissue with plump fibroblasts. Management and prognosis: After the incisional biopsy, surgical recontouring was done along with further regular follow up and observation. Conclusion: Diagnosis of the jaw lesions is based on clinical findings, radiographic features, and histological picture, whereas FOD can be diagnosed based on its clinical and radiographical features. Even though the surgical approach may lead to many complications like osteomyelitis, infection, fracture etc., a biopsy may be done to confirm the diagnosis.
ABSTRACT
Low water potential related stresses are regulated by modifying water uptake and loss to avoid low water potential, accumulating solutes which in turn enhance active principles and its gene expressions. Present study examined effect of in vitro induced absorption of mannitol and PEG (poly ethelene glycol) 6000 in Indian pennywort, Centella asiatica (L.) Urb., neutraceutical plant, evidenced by phenotypic, molecular and phytochemical analyses. Both mannitol and PEG 6000 induce water deficit conditions in plants and retarded normal plant biomass in terms of fresh and dry weights. These effects were significantly less severe in plants subjected to mannitol, compared to PEG. PEG and mannitol imposed water deficit, resulted in decline in major active compound, asiaticoside evidenced by HPTLC of asiaticoside content. Differential expression of some selected key genes in the asiaticoside pathway including squalene synthase and ? amyrin synthase by qPCR, confirmed decrease in transcript level expression of asiaticoside, whereas upregulated transcript level expression was observed in cycloartenol synthase for synthesis of phytosterols. Estimation of total flavonoids and phenolics under different water deficit conditions were found declined. In conclusion, water deficit by mannitol and PEG 6000 can significantly affects processes associated with biomass growth and ability to synthesize secondary metabolites in C. Asiatica.
