RESUMO
The aim of this study was to determine antioxidant activity of Brassica oleracea [Cabbage], Brassica rapa [Turnip] and Raphanus sativus [Radish]. All of the three selected vegetables were ultrasonically extracted in water and acetone. The antioxidant activity was determined by DPPH and H2O2. Highest phenolic, flavonoid and flavonol contents were found among water extract of Raphanus sativus, Brassica oleracea and Brassica rapa respectively. Highest %age of DPPH inhibition was exhibited by water extract of Brassica rapa and highest OH radical scavenging activity was shown by water extract of Raphanus sativus
RESUMO
Background: Dermatofibrosacoma protruberans [DFSP] is a rare, low to intermediate grade cutaneous sarcoma, with recurrence rates as high as 60%
Material and Methods: 11 patients were treated over a period of 5 years in Sheikh Zayed Hospital Lahore
Results: The tumors presented as asymptomatic nodule in 63.6% cases. Average size of tumor at the time of presentation was 8.5x6.6cm. Wide Local Excision [more than 3 cm] was done to reduce the chances of recurrence. Reconstruction of the excised lesions was carried out in the same sitting after frozen section examination of the tumor and margin clearance. 10 patients [90.1 %] were free from recurrence after a follow up of 24 months
Conclusion: Dermatofibrosarcoma protuberans is a rare, indolent tumor that presents as a local problem. Wide excision of margins has a favorable impact on recurrence free life interval. Frozen section analyses, margin clearance and reconstruction should be carried out during one operation. Fibrosarcoma variant of DFSP may behave more aggressively and radiation therapy may have a role in controlling recurrence of this sub group of tumor. We advocate wide local
