OBJECTIVE:
This research aimed to evaluate the protective effects of bioactive compounds such as phenolic acids, flavonoids, and tannins present in four species extracted with methanol.
METHODS:
The total phenolic content of the methanolic extracts was measured spectrophotometrically. The effect of the extracts on cell viability in U266 cells was measured. The effects of extracts on free radical scavenging were assessed by the DPPH test and FRAP assay. Antibacterial effects of the natural products in this report were investigated by using the disc diffusion method.
RESULTS:
Our results clearly demonstrated that the methanolic extracts were characterized by a high amount of phenolic compounds. It has been speculated that ME-TA and ME-TAl exhibit a significant (P < 0.05) and dose-dependent antiradical potential. The exposure of cells to high doses of extracts almost completely suppressed cell growth in vitro. ME-TA and ME-TAl showed significant cytotoxic effects at a concentration of 100 μg/mL in the U266 cell line. ME-TAl and ME-CF inhibited the growth of B. subtilis and S. aureus, respectively, to the same extent as 10 μg/μL of chloramphenicol at a concentration of 1 mg/mL.
CONCLUSION
Overall, these results suggest that plants used in traditional medicine have a novel application as free radical scavengers, bacterial inhibitors and tumor suppressors.

In this report, we describe an extremely unusual Monteggia equivalent type 1 lesion in a 10-year-old boy following a fall from a height of 1 m. On the plain radiographs, our patient had a particular Monteggia equivalent type 1 injury associating a posterior elbow dislocation with diaphyseal radius and ulna fractures. The patient was treated by closed reduction technique. At six months of follow-up, the fractures were consolidated and the elbow was stable. To our knowledge, only 8 adult cases and one paediatric observation with similar lesions had been reported through medical literature. Therefore, the aim of our case report is to remind this rare entity and also to provide a comprehensive review of the literature related to this uncommon lesion.
