We recently showed that the indolone-N-oxides can be promising candidates for the treatment of chloroquine-resistant malaria. However, the in vivo assays have been hampered by the very poor aqueous solubility of these compounds resulting in poor and variable activity. Here, we describe the
Serum levels of total protein, albumin, activity of hemolytic complement, and complement component C3 were decreased in cattle infected with either T. congolense or T. vivax. The hemolytic complement activity was reduced most, i.e. to 20% (T. congolense) or 5% (T. vivax) of control levels. The
The paper summarizes the results of clinical examinations of imported malaria in 48 patients, semi-immune foreigners infected with P. falciparum and P. vivax/P. ovale. Of the objective manifestations, hepatosplenomegaly was predominant in P. falciparum infections (34%), whereas in P. vivax
Trypanosomosis has been associated with immunosuppression, anemia and oxidative damage while selenium possesses both immunostimulatory and antioxidative effects. This study was designed to assess the effect of dietary selenium supplementation on parasitemia, anemia, survival pattern and serum
Infections by Trypanosoma vivax cause great losses to livestock in Africa and Central and South Americas. Outbreaks due this parasite have been occurred with increasing frequency in Brazil. Knowledge of changes caused by T. vivax during the course of this disease can be of great diagnostic value.
Serum albumin and glucose concentrations and urinary excretion of alpha-keto acids and proteins were determined in samples obtained throughout a chronic Trypanosoma brucei gambiense infection in Microtus montanus. An increase in urinary excretion of alpha-keto acids and proteins during the terminal
The course of an experimental Trypanosoma evansi infection in coatis (Nasua nasua, carnivora, Procyonidae) was followed for 262 days. Hematological analysis of the infected coatis revealed a marked decline in hemoglobin, packed-cell volume, and total erythrocyte count. An intense anemia followed the
We performed a series of studies to examine the sequential development of nephritis during murine malaria infections and to define the role of DNA-binding antibodies in the associated pathology. Serum levels of these antibodies were assessed throughout acute and chronic malaria infections. Increased
Mice are considered to be a similar model to humans in the pathogenesis of malaria. This study evaluates the effect of parenteral antimalarials on the spleen and liver of Swiss albino mice after chronic exposure to Plasmodium berghei. After chronic exposure to P. berghei NK65 strain,
More than 40 years after its discovery, artemisinin has become the most promising antimalarial agent. However, no intravenous formulation is available due to its poor aqueous solubility. Here, we report the preparation, characterization, and in vitro and in vivo biological evaluation of
OBJECTIVE
Phytochemical constituents as well as antimalarial and toxicity potentials of the methanolic extract of the husk fibre of Dwarf Red variety of Cocos nucifera were evaluated in this study.
METHODS
The dried powdered husk fibre was exhaustively extracted with hexane, ethyl acetate and
The present study aimed to evaluate the effects of Trypanosoma vivax infection on the shape of the lactation curve and the milk quality of dairy goats experimentally infected with T. vivax. In total, twenty Saanen goats, aged 26-30 months and the same number of calving (two calvings), were divided
It is currently accepted that malaria-parasitized red blood cells (pRBC) are eliminated, like senescent erythrocytes, phagocytically by macrophages in the red pulp of the spleen. Here, however, we show that self-healing Plasmodium chabaudi malaria activates spleen closure in C57BL/6 mice. Confocal
To study the risk factors for Plasmodium vivax gametocyte carriage, the presence or absence of gametocytes was determined in 2,125 patients with P. vivax malaria participating in clinical trials at the Hospital for Tropical Diseases in Bangkok, Thailand. Stepwise logistic regression models were used
An enzyme-linked immunosorbent assay for rapid detection of malarial antibodies and antigens was developed. Plasmodium falciparum antigen preparation, obtained from sonicated cultures of the parasite at a parasitemia of 10%-15%, was applied to cellulose filter discs in volumes of 0.1 microliter in
