The present study of Physicochemical Analysis of bore wells water Qualities of some rural Area of Osmanabad district of Maharashtra during pre-monsoon 15 may 2022 to 15 June 2022. Ten ground water samples (ws -1 to ws -10) were collected from bore wells of different sampling sites of Osmanabad district. Ten ground water samples (ws -1 to ws -10) were collected from bore wells of different sampling sites of Osmanabad district. They were analyzed for physicochemical parameters such as temperature range between 22.50C to 23.09 0C and the average of ws-1 to ws-10 is 23.08 0C. The pH value range between 7.2 to 7.8 & the pH value average of ten different bore wells ws-1 to ws-1o is 7.46, The TDS value for ten different bore wells water ws-1 to ws-10 are in the range between 210 to 283 mg/l & the TDS value average of ten different bore wells is 249.8 mg/l. The electrical conductivity (EC) value range between 510 to 595 us/cm. & the electrical conductivity value average of ten wells water is 545.6 us/cm. The total Alkalinity value for all bore wells water ws-1 to ws-10 range between 225.5 to 341.5 mg/l and the total alkalinity value average of ten different bore wells water is 286.86mg/l. The residual sodium carbonate value for ten different bore wells water range between 0.06 to 3.45mcq/l. The RSC value of ws- 5 are lowest than ws-7 is highest3.45mcq/l. The RSC average of ten different bore wells water 1.73 mcq/l. The SAR range between 1.0 to 3.5. The SAR value of ws-5 are1.0 lowest than ws-7 is highest 3.5& average of ten different bore wells is 1.68 recorded in Osmanabad district.

Ameloblastoma, a relatively common epithelial odontogenic tumor includes several histopathologic subtypes like follicular, plexiform, acanthomatous and desmoplastic variants. Hybrid desmoplastic ameloblastoma (DA) composed of typical desmoplastic ameloblastoma along with areas of follicular/plexiform ameloblastoma is an extremely rare variant of ameloblastoma and to date only 16 cases have been documented. We report a new case of hybrid DA which additionally showed remarkable histologic findings of extensive bone formation and presence of mucous cells. It occurred in a 64 year old female patient involving the left maxilla from lateral incisor to distal to first molar. A comprehensive review of hybrid DA and the unusual findings aimed to offer an insight into the pathogenesis of these heterogeneities in odontogenic epithelium and clinical implications was also undertaken. Hybrid DA showed characteristic clinicopathologic features of a desmoplastic ameloblastoma with the exception of predominant mandibular occurrence. A likelihood of areas of solid multicystic ameloblastoma being a part of histopathologic spectrum of DA questioning the need for use of term “hybrid” was observed. Regarding the osteoplasia, most cases occurred in Asians and in anterior maxilla. The prominent TGF-β expression seen in our case adds emphasis to its role in desmoplasia and osteoplasia. Furthermore, we identified an interesting association of desmoplasia with incidence of mucous cell metaplasia in ameloblastoma. Key words: Ameloblastoma; hybrid desmoplastic ameloblastoma, osteoplasia, mucous cells, TGF-β
