ABSTRACT
@#Diplazium esculentum is an edible fern commonly consumed by the local community in Malaysia either as food or medicine. Isolation work on the ethyl acetate extract of the stem of D. esculentum resulted in the purification of two steroids, subsequently identified as stigmasterol (compound 1) and ergosterol5,8-endoperoxide (compound 2). Upon further testing, compound 2 displayed strong inhibitory activity against the Plasmodium falciparum 3D7 (chloroquine-sensitive) strain, with an IC50 of 4.27±1.15 µM, while compound 1 was inactive. In silico data revealed that compound 2 showed good binding affinity to P. falciparum-Sarco endoplasmic reticulum calcium-dependent ATPase (PfATP6); however, compound 1 did not show an antiplasmodial effect due to the lack of a peroxide moiety in the chemical structure. Our data suggested that the antiplasmodial activity of compound 2 from D. esculentum might be due to the inhibition of PfATP6, which resulted in both in vitro and in silico inhibitory properties.
ABSTRACT
Chronic Suppurative Otitis Media (CSOM) is one of the important health problems in our country. Serious complications may arise from it. As such the study was aimed to find out the prevalence of CSOM among the children of two-selected slum dwellers in Dhaka City. This was a descriptive type of cross-sectional study. A total of 203 samples were interviewed and examined. Altogether 7.39% of children were observed to have CSOM. Among CSOM cases, 60% had hearing impairment. Ear discharge and perforation were observed in 26.7% in right ear, 46.7% in left ear and 26.7% in both ears. Central perforation was present in 93% cases. Cholesteatoma was present in 6.7% cases. Among CSOM cases, 53.3% children were in 2-5 years age group, 80% were dependent, 53.3% cleaned ear by cotton buds, 93.3% lived in Kutcha house, 73.3% had a monthly income of TK. 1001-2000 and 46.7% belonged to families having 6 members. Out of 15 CSOM, 11 cases were seen among children of 141 illiterate mothers. Four cases of CSOM were found among children of 62 literate mothers. Among the 203 mothers, 65.52% were found aware, and 34.48% were not aware about the disease and sequel of CSOM. Here 39.9% mothers had knowledge and 60.01% had no knowledge about the treatment of CSOM. Among the CSOM cases 46.67% cases did not receive any treatment. In treatment receiving group, only 3(20%) children received it from MBBS doctor or Hospital.
