Foreign body ingestion among children is common and
most usually pass through the gastrointestinal tract without
requiring any intervention. Magnets, however, pose a greater
threat especially when more than one are ingested. We
report a case of multiple bowel perforation secondary to
ingestion of magnetic beads in a 3-year-old.

Introduction: Aquilaria malaccensis, also known as “Pokok Karas” in Malaysia, is widely used in Southeast Asian
countries for the treatment of joint pain, diarrhoea and inflammatory diseases, and has shown beneficial effects as
an anticancer agent. The aim of this study was to investigate the effect of ethanol leaf extracts of A. malaccensis on
MCF-7 cells. Methods: MTT-based cytotoxic and antiproliferative assay was used to determine the outcome of ethanolic extract toward MCF-7 cells. The mode of cell death was determined by the AO/PI double staining assay and
the depolarisation of the mitochondria membrane potential. Results: IC50 value of the extract against MCF-7 cells
treated for 72 hours was 4.1 ± 2.08 µg/mL, while the IC50 value for doxorubicin was 2.92 ± 0.12 µg/mL. The extract
showed a lower cytotoxic effect against the NIH/3T3 cells and inhibited the growth of MCF-7 cells in a dose dependent manner. AO/PI double stain showed that the ethanolic extract of A. malaccensis leaves induced MCF-7 cells
into apoptotic cell death. The present study showed that the ethanolic extract of A. malaccensis induced apoptosis
through mitochondrial pathway as indicated by its ability to take up JC-1. Conclusion: The study found that ethanolic
extract obtained from A. malaccensis leaves is cytotoxic on MCF-7 cells, resulting to apoptotic cell death of the cells.
