There are a number of forefoot pathologies that can present similarly to sesmoid pathologies and likewise identifying the particular cause of sesamoid pain can be challenging. Modern imaging techniques can be helpful. This article reviews the anatomy,development and morphological variability present in the sesamoids of the great toe. We review evidence on approach to history, diagnosis and investigation of sesamoid pain. Differential diagnoses and management strategies, including conservative and operative are outlined. Our recommendations are that early consideration of magnetic resonance imaging and discussion with a specialist musculoskeletal radiologist may help to identify a cause of pain accurately and quickly. Conservative measures should be first line in most cases.Where fracture and avascular necrosis can be ruled out,injection under fluoroscopic guidance may help to avoid operative intervention.展开更多

In order to justify the use of C. sesamoides and S. hermonthica in the treatment of gastrointestinal parasitosis of small ruminants, a quantification of phenolic compounds as well as antioxidant activity and acute toxicité evaluation of both plants were performed. Acute toxicity was evaluated by administering a single dose of 2000 mg/kg body weight of aqueous extract of both plants to mice. The highest total polyphenol content for C. sesamo?des was obtained in the ethyl acetate fraction with 47.236 ± 2.57 mgEAG/100mg while that of S. hermonthica was 74.871 ± 2.57 mgEAG/100mg obtained with the n-butanol Fraction. The dichloromethane extract of S. hermonthica obtained the highest total flavonoid content with 7.31 ± 0.48 mgEQ/100 while the highest total flavonoid content of C. sesamo?des was obtained with ethyl acetate fraction with 5.4273 ± 0.35 mgEQ/100mg. The aqueous extract of C. sesamo?des obtained the highest content of condensed tannins with 3.028 ± 0.13 mgEAT/100mg. Both plant’s extracts did not show any signs of toxicity in NMRI mice after administration of the dose of 2000 mg/kg. The antioxidant activity by DPPH, FRAP and ABTS methods was good compared to those of Quercetin and Trolox taken as standard.展开更多
