The aim of the present study was to investigate the positive influence of chloroquine and artesunate on the pathological damages caused by Plasmodium berghei on vital organs of mice in an established infection. Healthy adult albino mice with average weight of 25 g were used for the study. Treated group was administered orally with 100 mg/kg of chloroquine and artesunate, respectively. Control a...

There is increasing resistance of malaria parasites to chloroquine, the cheapest and commonly used drug for malaria in Nigeria. Artemisin, a product from medicinal plant indigenous to China, based on active principle of Artemisia annua, has been introduced into the Nigerian market. However not much has been done to project antimalaria properties of indigenous medicinal plants. This study thus, ...

BACKGROUND Antimalaria treatment failure has been partly attributed to poor quality antimalarials in the drug market. A 1998 survey in Kampala showed that 55% of tablets and 62% of injection forms of chloroquine failed the quality test. OBJECTIVE This study was carried out as a follow-up to establish the quality of chloroquine tablet and injection dosage forms in the Ugandan drug market from ...

Plasmodium vivax merozoite surface protein 1 (PvMSP-1) has been considered a major candidate for the development of an antimalaria vaccine, but the molecule exhibits antigenic diversity among isolates. The extent of genetic polymorphism in the region between interspecies conserved blocks 4 and 5 (ICB4 and ICB5) of the PvMSP-1 gene was analyzed for 30 Korean isolates. Two genotypes, SK-A and SK-...

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...

alpha-Galactosylceramide (alpha-GalCer) is a glycolipid that stimulates natural killer T cells to produce both T helper (Th) 1 and Th2 cytokines. This property enables alpha-GalCer to ameliorate a wide variety of infectious, neoplastic, and autoimmune diseases; however, its effectiveness against any one disease is limited by the opposing activities of the induced Th1 and Th2 cytokines. Here, we...

Despite declining the number of malaria cases in Iran, increased prevalence of malaria is supposed to be due to migration from eastern neighboring countries of Iran, which are abundant in Plasmodium vivax (P. vivax). The circumsporozoite protein (CSP) of the P. vivax, is one of the candidate antigens for antimalaria vaccine. The diversity of P. vivax populations circulating in Iran has been inv...

BACKGROUND & OBJECTIVES The distribution of insecticide-treated bednets (ITNs), as an alternative to untreated bednets or no bednet at all, not only directly prevents the mosquito from biting an individual, but kills the mosquito as well. This reduces the mosquito infestation at the household and community levels. However, barriers may exist limiting the effectiveness of malaria prevention by t...

Background. Plasmodium yoelii 17XNL is a nonlethal malaria strain in mice of different genetic backgrounds including the C57BL/6 mice (I-Ab/I-Enull) used in this study as a control strain. We have compared the trends of blood stage infection with the nonlethal murine strain of P. yoelii 17XNL malaria protozoan in immunocompetent Nonobese Diabetic (NOD) mice prone to type 1 diabetes (T1D) and C5...
