In this retrospective study, we present our experience using open Küntscher nailing (K-nailing) which is still performed in developing countries for femoral fractures. Of 157 acute fractures treated between January 2003 and December 2009, 100 were stable (63.7%) and 135 were located within the middle third of the shaft (86%). Comminution was absent or minimal in 135 (86%) cases. Fracture union was achieved at an average of 14 weeks (range, 10 - 25). The duration of follow-up was 17 months (range, 6 - 36). Final evaluation showed that 129 (82.2%) patients had a good result according to modified Kempf’s criteria. The predominant complications were infection (n=5; 3.2%), nonunion (n=9;5.5%), implant failure (n=11; 7%), and malunion (n=27; 17.3%). Open reduction and fixation with a tight fitting Knail can give good results in selected acute femoral shaft fractures but knowledge of potential complications is needed.

Waste hops are good sources of flavonoids. Extraction of flavonoids from waste hops (SC-CO(2) extracted hops) using supercritical fluids technology was investigated. Various temperatures, pressures and concentrations of ethanol (modifier) and the ratio (w/w) of solvent to material were tested in this study. The results of single factor and orthogonal experiments showed that at 50 degrees C, 25 MPa, the ratio of solvent to material (50%), ethanol concentration (80%) resulted in maximum extraction yield flavonoids (7.8 mg/g). HPLC-MS analysis of the extracts indicated that flavonoids obtained were xanthohumol, the principal prenylflavonoid in hops.

Objective To evaluate the anthelmintic property of Saba senegalensis (A.DC) Pichon (Apocynaceae) (S. senegalensis) on Haemonchus contortus that is traditionally used in Burkina Faso for its gastrointestinal parasites treatment. Methods The lyophilized aqueous decoction of leaves of S. senegalensis at concentrations of 0.10, 1.00, 3.00, 10.00 and 15.00 mg/mL was used on eggs and adult worms of Haemonchus contortus collected from gastrointestinal tract of small ruminant. Results The LC
