In vitro antioxidant activity and total phenolic content of endophytic fungi isolated from Eugenia jambolana Lam

OBJECTIVE@#To elucidate the antioxidant activity and total phenolic content (TPC) of ethyl acetate extracts of endophytic fungi isolated from Eugenia jambolana by three different antioxidant assays.@*METHODS@#Twenty one different endophytic fungal extracts were screened for presence of various phytochemicals, TPC and in vitro antioxidant activity. TPC was tested by Folin-Ciocalteau reagent based assay. DPPH free radical scavenging, hydrogen peroxide scavenging and reducing power assays were used to evaluate the antioxidant activity.@*RESULTS@#Alkaloids, phenols, flavonoids, saponins, and terpenes were the main phytochemicals presents in all 21 endophytes. A significant positive correlation was found between antioxidant activity and TPC in fungal extracts. There is 36% endophytic extracts having high phenolic content exhibited potent antioxidant activity. Chaetomium sp., Aspergillus sp., Aspergillus peyronelii and Aspergillus niger strain showed the highest antioxidant activity ranging from 50% to 80% having 58 mg/g to 60 mg/g GAE total phenolics. Ascorbic acid used as a standard showed 90% reducing potential.@*CONCLUSIONS@#The results reveal that metabolites produced by endophytic fungi isolated from Eugenia jambolana can be a potential source of novel natural antioxidant compounds.

Intralobar pulmonary sequestration in right lower lobe with secondary infection in an adult male

Pulmonary sequestration is a rare congenital bronchopulmonary foregut malformation in which a segment of lung parenchyma is not connected to the tracheobronchial tree. This abnormal segment receives blood supply from the systemic circulation. Varying clinical techniques have been utilized to manage this disease process including surgical intervention, endovascular procedures and operative approaches. The most common presentation of this entity is involvement of the left lower lobe. We present a rare case of intralobar pulmonary sequestration in an adult male involving the right lower lobe with secondary infection

Dedifferentiated Chondrosarcoma of the Rib Masquerading as a Giant Chest Wall Tumor in a Teenage Girl: An Unusual Presentation

Chondrosarcoma of the chest wall is a rare primary neoplasm found to occur in elderly men. Patients present with an enlarging, painful, anterior chest wall mass arising from either the vicinity of the costochondral junction or the sternum. Treatment includes wide resection with appropriate chest wall reconstruction. We report an unusual presentation of this uncommon tumor occurring as a huge chest wall mass in a young teenage girl.

Coexistent pulmonary hydatid disease and tuberculosis in an adult male

Hydatid disease with pulmonary tuberculosis coexisting in a patient is an extremely rare occurrence. A patient presenting with nonspecific chest symptoms must be adequately investigated and hydatidosis must be ruled out. This case report presents the unusual coexistence of tuberculosis and hydatid disease in an adult male and its subsequent diagnosis and management
