PURPOSEFirearm injuries impose a continuous economic burden on society and hospital resources. The aim of this study was to assess the pattern of bony injuries among victims of gunshots.

METHODSA retrospective study was conducted in the Department of Orthopedics, Dow University of Health Sciences and Civil Hospital Karachi from January 2011 to December 2012. Patients with isolated bony injuries were included while patients with other systemic injuries were excluded.

RESULTSThere were 90 cases and the majority of them were male (84.4%). Mean age was (32.52 ± 10.27) years. Most of the patients (72.2%) belong to the younger age group. A low velocity weapon was used in 61 (67.8%) cases and a high velocity weapon was used in 29 (32.2%) cases. Armed robbery (64.4%) was the cause of conflict in more than half of the cases. Lower limb was involved in 72.2%. Fifty eight (64.4%) patients remained hospitalized for 15-20 days and others for more than 20 days. Internal fixation with intramedullary nailing was done in 35 patients while K-wire was used in 5 patients. Fifty patients were managed with external fixation, either uniplanar or multiplanar ilizarov. Deep wound infection and nonunion were observed more often in high velocity injuries.

CONCLUSIONArmed robbery was the leading cause of gunshot bony injuries in our hospital. Young males were victimized in a majority of cases. High velocity injuries were associated with more complications.

Objective: To evaluate the phytochemical and in vitro antioxidant ability of methanolic extract and different fractions of Amaranthus graecizans subsp. silvestris (A. graecizans subsp. silvestris). Methods: Methanolic extract of A. graecizans subsp. silvestris was obtained by cold maceration and then methanolic extract was subjected to fractionation and different fractions i.e. n-hexane, chloroform, ethyl acetate, n-butanol and aqueous fractions were obtained. Methanolic extract and all other fractions were subjected to phytochemical investigation by performing different phytochemical group tests like alkaloid, tannins, carbohydrates, lipids, proteins, etc. In vitro antioxidant activity of A. graecizans subsp. silvestris was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl radical (DPPH), ferric thiocyanate assay, total antioxidant activity by phosphomolybdenum, ferric reducing antioxidant power, total phenolic content and lipid peroxidation methods. Results: Maximum antioxidant activity was shown by n-hexane fraction of the extract by carrying out DPPH (86.44±0.23), ethyl acetate fraction by total antioxidant (0.95±0.06) and ferric reducing antioxidant power (299.45±1.48) methods, while by employing total phenolic contents and inhibition of lipid per oxidation assays, methanolic extract (92.88±4.16) and n-hexane fraction (69.47±0.68) exhibited maximal activity. Ethyl acetate fraction showed the least IC
