Pattern of Wuchereria bancrofti microfilaraemia in young and adolescent school children in Bassein, India, an endemic area for lymphatic filariasis

Filariose bancroftiana em áreas urbanas do Estado de Alagoas, nordeste do Brasil: estudo em população geral

“…Esses dados, aliado ao fato de que as maiores prevalências de bancroftose ocorrem em grupos etários mais jovens 15 , podem explicar porque a amostra de escolares noturnos examinada previamente 6 , com mé dia de idade 18,4 ± 4,6 anos, foi r e p r e s e n t a t i v a p a r a a d i s t r i b u i ç ã o d e microfilarêmicos na população geral da área urbana da capital alagoana que possui uma média de idade 24,0 ± 18,2 anos 7 . Assim, a amostra de escolares noturnos que é mais fácil de ser obtida, pode ser adequada para estudos futuros de avaliação de programas de controle da parasitose na área, diminuindo tempo e custos operacionais.…”

Lymphatic Filariasis in Brazilian Urban Area (Maceió, Alagoas)

“…Comparison between examined and not-examined students (age and sex) did not reveal any difference; no evidence was found linking school absence to W. bancrofti positivity. Evening students were chosen as the study popu- lation due to (1) relatively higher prevalences of microfilaraemia in adolescents and young adults (Vincent et al 1981, Vanamail et al 1989, Rajasekariah et al 1991 and (2) the parasite's nocturnal periodicity in the region (Rocha et al 1991). Although cluster sampling was used in selecting participants, the data analysis conducted assumed simple random sampling.…”

Comparative Evaluation of Phytochemicals in Methanolic and Ethanolic Leaf Extracts of Anticancer Paradise Tree Simarouba glauca DC

“…Extracts were used to detect the presence of secondary metabolites like alkaloids by mixing 2mL of extract with 1% HCl, followed by boiling and treatment with 6 drops of Mayer's reagent (Chhetri, 2008 ;Parekh, 2007;Evans, 1989), presence of phenol was detected by phenol and ellagic acid test (Mallikharjuna, 2007, Dey & Harbour, 1987, Evans, 1989, flavonoids by Alkaline reagent test (Mallikharjuna, 2007, Dey & Harbour, 1987, Evans, 1989 and flavonoid test (Mallikharjuna, 2007, Dey & Harbour, 1987, Evans, 1989, tannin by mixing crude extract with 2mL of 2% FeCl 3 solution (Mallikharjuna, 2007, Chhetri, 2008, Doss, 2009, lignin by treating crude extract with 2mL of furfuraldehyde (Mallikharjuna, 2007, Dey & Harbour, 1987, Evans, 1989, steroids by Salkowski's test (Mallikharjuna, 2007, Dey & Harbour, 1987, Evans, 1989, glycosides by mixing crude extract with 2mL of glacial acetic acid containing 1-2 drops of 2% sol of FeCl 3 followed by addition of 2mL of H 2 SO 4 (Krishnaiah, 2009;Edeoga, 2005;Doss, 2009), saponins by shaking the crude extract with water (Dey & Harbour, 1987;Evans, 1989), tepenoides by Salkowski test (Rajasekariah et al, 1991) and anthraquinone by mixing the crude extract with 2mL of chloroform and conc.
