Background: The capacity of human HbAA erythrocytes of non-malarious blood to withstand osmotic stress in the presence of five antimalarial drugs, Chloroquine phosphate, Quinine, FansidarTM, CoartemTM and HalfanTM was studied in vitro. Materials and Methods: Aqueous solutions of four increasing concentrations of the drugs used in this investigation were in the order: 0.2%, 0.4%, 0.6% and 0.8% (...

Due to the deteriorating efficacy of sulfadoxine-pyrimethamine (SP or Fansidar), from the mid-1970s the Thai Malaria Control Program was actively involved in testing potential replacement drugs to be used as the primary therapy for falciparum malaria in Thailand. In 1983, a large-scale field trial of mefloquine, a long-acting antimalarial drug known for its efficacy against chloroquine- and SP-...

INTRODUCTION Home-based management of malaria is promoted as a major strategy for improving prompt delivery of effective malaria treatment in Africa. This study aimed to determine the proportion of children who tested positive for malaria with routine light microscopy among those whose mothers had made a home-based diagnosis in a rural community in Western Kenya. METHODOLOGY This cross-sectio...

Background: Malaria remains the world’s most devastating human parasitic infection. Our goal was to assess the capacity of increasing concentrations of five antimalarial drugs (Fansidar, Halfan, Quinine, Coartem and Chloroquine phosphate) to elicit the generation of methemoglobin in three human erythrocyte genotypes (Hb AA, Hb AS and Hb SS). Materials and Methods: Spectrophotometric method was ...

The study objective was to determine plasma concentration of pyrimethamine in 24 infants aged 1-5 months, treated for congenital toxoplasmosis. Pyrimethamine was used in a single daily dose at an amount of 0.35-0.98 mg/kg daily, with sulfadiazine (50-100 mg/kg/day) in divided doses 2-3 times a day, and folinic acid given twice a week (7.5 mg). This regimen was continued for 2-6 months, then Fan...

BMJ 1993;306:1247-52 To provide revised guidance on malaria prevention for the medical advisers oftravellers from the United Kingdom going overseas to malarious areas, a committee of those most involved in giving advice and with specialist expertise in the United Kingdom agreed a policy document. There is a need for all travellers to be aware of the risk of malaria and to take measures to avoid...

background: the recently reported resistance to antimalarials contributes to making the control of ma­laria more difficult. there is a need to evaluate the current antimalaria regimens to prevent this emerging problem. the aim of this study was to determine dihydrofolate reductase-thymidylate synthase gene mu­tation ( pvdhfr ) regarding antifulate resistance in plasmodium vivax . methods : from...

Feline enteric coronavirus (FECV) infects enterocytes and causes inflammation of the intestinal mucosa in young cats, resulting diarrhea. In adult cats infection is usually asymptomatic, but constant circulation FECV feline population increases likelihood mutation, as a result which about 5-10% infected develop virulent strain virus that lethal infectious peritonitis – FIP. The purpose this stu...
