some aspects of epidemiology of resurgent malaria in turkey.the resurgence of autochthonous plasmodium vivax malaria in turkey is a matter of considerable concern. anopheles sacharovi is the important vector but other species, notably a. superpictus, may play a role in transmission. the epidemiology is discussed in terms of factors related to the mosquito, factors related to the human host and human ecology as it affects dispersal of the parasite. although the development of insecticide resistance is grave, the present situation is mainly attributable to ...1978366812
chronic malarial infection of mice: a comparison of single and multiple infections with plasmodium berghei following p. yoelii.chronic malarial infection was induced in two groups of balb/c mice by injection of plasmodium yoelii followed by either one or repeated injections of p. berghei. both groups showed a continuing but fluctuating splenomegaly, and a considerably increased reticulocyte count which also varied regularly, over a period of six months. during this time many mice had a very low grade parasitaemia demonstrable by subinoculation of blood into uninfected recipients. mice infected with p. yoelii alone did n ...1978366816

the protective effect of endogenous interferon in mouse malaria, as demonstrated by the use of anti-interferon globulins.both death rate and percentage of parasitized erythrocytes in mice infected with plasmodium berghei were enhanced by injections of anti-interferon globulins. as, in the same time, parasite-induced interferon was neutralized by these globulins, it can be concluded that endogenous interferon plays an important inhibiting role during parasitic diseases, such as malaria, as it has been previously demonstrated in many virus infections.1978367460
malaria in birmingham and a london teaching hospital.during the past five years the incidence of imported malaria increased among patients seen in east birmingham hospital and in st thomas's hospital, london. plasmodium vivax was the predominant species in birmingham, and was almost always acquired by asian immigrants visiting the indian subcontinent. in st thomas's p falciparum was most commonly imported, usually by african immigrants visiting nigeria and ghana. two patients (one irish, one japanese) died of falciparum malaria after visiting trop ...1979367507

antimalarials. 4. trichloronaphthalene amino alcohols.an improved procedure for the synthesis of naphthalene amino alcohols is described. four new compounds were prepared and tested by rane laboratories for activity vs. plasmodium berghei in mice. all compounds were active, the most active being 1-[3-(4-chlorophenyl)-5,7-dichloro-1-naphthyl]-3-(di-n-butylamino)propanol hydrochloride (16b). structure--activity relationships between the naphthalene and quinoline isosteres are discussed.1979370389
chloroquine resistance in malaria: accessibility of drug receptors to mefloquine.the process of mefloquine accumulation was studied in mouse erythrocytes infected with either plasmodium berghei cs (chloroquine susceptible) or p. berghei cr (chloroquine resistant). in both cases, mefloquine was accumulated by a saturable process with an apparent dissociation constant of 2.5 x 10(-6) m and an apparent maximal capacity of 700 mumol per kg of erythrocyte pellet; uninfected mouse erythrocytes accumulated more than half as much mefloquine as infected erythrocytes. the process of a ...1979371544
the role of platelets in infections. i. observations in human and murine malaria.the interaction between platelets and microorganisms may be underestimated. our in vivo studies support a direct role of thrombocytes in malarial infections. we have found intrathrombocytic parasites of plasmodium vivax (in 10% of men naturally infected) and p berghei (in 53% of mice experimentally infected); these were both merozoites and trophozoites. neither the mechanism of parasitization (whether by active penetration or by phagocytosis) nor the outcome of this phenomenon is known. however, ...1979371580
separation of plasmodium berghei-parasitized rat erythrocytes by means of carrier-free electrophoresis.a carrier-free electrophoresis apparatus was used to isolate rat erythrocytes parasitized with plasmodium berghei. the region of high electrophoretic mobility yielded noninfected erythrocytes, whereas that of low electrophoretic mobility yielded erythrocytes infected with viable parasites. over 98% purity of parasitized erythrocytes was obtained when blood at an advanced stage of parasitaemia was used. merozoite-rich fractions were also observed. this continuous one-step separation method should ...1979371849
concentration and separation of erythrocytes infected with plasmodium falciparum by gradient centrifugation.concentration of infected erythrocytes was achieved in cell suspensions derived from long-term culture of plasmodium falciparum growing asynchronously in human erythrocytes. this new procedure involves the slow centrifugation (at 33 g) of erythrocyte suspensions through 5% ficoll solutions. mature asexual erythrocytic forms are preferentially retained in the gradient solution (top fraction). after further gradient centrifugation of these parasitized cells, the concentration of mature forms is in ...1979371850
direct coombs antiglobulin reactions in gambian children with plasmodium falciparum malaria. i. incidence and class specificity.gambian children with past or present plasmodium falciparum malaria were investigated for the incidence of coombs positivity using monospecific antisera. approximately 50% were positive and the most frequent form of erythrocyte sensitization was with c3d. other specificities, eigg, eiggc3d and eiggc4bc3d were less common. erthyrocytes were never found sensitized with iga or igm. there was no correlation between a positive test and age, tribal status or level of parasitaemia at presentation, alth ...1979371880

[course and intensive treatment of acute falciparum malaria (author's transl)].the case of a nineteen-year-old women with the cerebral form of malaria tropica is reported. she showed hyperpyrexia, abdominal manifestations, haemolysis and disseminated intravascular coagulation. cerebral symptoms amounting to grade iv encephalopathy occurred. the patient responded rapidly to the administration of chloroquine, anticonvulsants, dextran, corticosteroids, antipyretics, blood and antithrombin iii and her symptoms had almost completely vanished one week after the onset of therapy.1979373259
effect of temperature and clofibrate on plasmodium berghei infection in mice.parasitemia counts established that 22 degrees c-acclimated mice subjected to cold exposure for a short time (-35 degrees c for 30 min) during plasmodium berghei infection had significantly higher parasitemia levels than parasitized mice continuously housed at 22 degrees c. parasitized 5 degrees c-acclimated mice also demonstrated higher parasitemia levels than parasitized 22 degrees c-acclimated mice. there was no correlation between plasma free fatty acid (pffa) concentration and parasitemia i ...1979373470
host defenses in murine malaria: successful vaccination of mice against plasmodium berghei by using formolized blood parasites.infections of normal icr mice with the nyu-2 strain of plasmodium berghei (pb) are uniformly fatal. however, a proportion of mice that have been vaccinated with a formalin-killed antigen prepared from the blood stages of pb survive an otherwise lethal challenge. such immunity is not induced by immunization with normal mouse erythrocytes. the level of acquired anti-malarial immunity is related to the size and number of doses of antigen, and intravenous injection is superior to the subcutaneous ro ...1979373471
hepatic dysfunction in childhood malaria.hepatic function of 80 children aged under 3 years with plasmodium vivax malaria were studied during the acute attack and 6 weeks after antimalarial treatment. raised levels of serum aspartate transaminase (serum ast; sgot), serum alanine transaminase (serum alt; sgpt), and alkaline phosphatase were observed in 68%, 39% and 46% of cases respectively. ast levels were higher than alt ones and the mean level of both enzymes was much higher in patients with hepatomegaly. the hepatic dysfunction whic ...1979373643
single-dose therapy of falciparum malaria with mefloquine or pyrimethamine-sulfadoxine.a single oral dose (1.5 g) of mefloquine hydrochloride cured all of 37 patients with falciparum malaria, and a single dose of pyrimethamine (75 mg) plus sulfadoxine (1.5 g) cured 34 of 38 patients. the rates at which parasitaemia and fever abated were similar for the two regimens but mefloquine was associated with a higher incidence of gastrointestinal side effects.1979373903
loss of circulating t lymphocytes with normal levels of b and 'null' lymphocytes in thai adults with malaria.peripheral blood mononuclear cells from forty-nine thai adults infected with either plasmodium falciparum or plasmodium vivax were examined in order to determine the percentage of t, b, and fc-receptor-bearing cells present. in comparison to healthy controls, both the percentage and concentration of peripheral t cells were decreased in the malaria-infected individuals as assessed by formation of rosettes with sheep red blood cells. the percentage of peripheral b cells was increased but their co ...1979373935

intravascular clearance of parasitized erythrocytes in rodent malaria.little is known about host defense mechanisms responsible for protective immunity in malaria. the intravascular location of the infection suggested that removal of parasitized erythrocytes by reticuloendothelial organs might be important. to study this possibility, we examined the clearance of (51)crlabeled plasmodium berghei-infected erythrocytes in rats. infected erythrocytes were removed more rapidly from circulation than homologous uninfected erythrocytes. the rate of clearance of infected c ...1979376554
circulating and tissue-bound immune complex formation in murine malaria.immune complex formation during plasmodium berghei infection of of1 mice was investigated. circulating immune complexes (cic) were detected by the clg-binding assay and the conglutinin-binding solid-phase assay in lethal or drug-limited infections. cic appeared on day 9 of infection, peaked on day 11, and disappeared only after complete cure of the infection. analysis of the immune complexes detected by the clq-binding assay revealed the following characteristics: sedimentation coefficients of 1 ...1979376733
hemolymph of anopheles stephensi from uninfected and plasmodium berghei-infected mosquitoes. 2. free amino acids.determinations were made of free amino acids in hemolymph collected from adult female anopheles stephensi mosquitoes. the hemolymph first was fractionated by extraction and precipitation procedures, after which qualitative determinations of free amino acids were made by high voltage thin layer electrophoresis, and thin layer chromatography. subsequent quantitative determinations were made with an automatic amino acid analyzer. the concentration of total free amino acids in the hemolymph rose 60- ...1979376812
hemolymph of anopheles stephensi from noninfected and plasmodium berghei-infected mosquitoes. 3. carbohydrates.determinations were made of carbohydrates in hemolymph collected from adult female mosquitoes (anopheles stephensi). first the hemolymph was fractionated by extraction and precipitation procedures, after which qualitative and quantitative determinations of carbohydrates were made by thin layer chromatography. the most abundant sugars found in the hemolymph were glucose and trehalose, though maltose, glucuronic acid, and inositol could be found after the mosquitoes took blood meals. after the mos ...1979376818
isolation of plasmodium berghei by hemolysin lysis of infected erythrocytes and evidence for a parasite hexokinase.a rapid and simple procedure has been developed for the isolation of plasmodium berghei parasites from infected-mouse erythrocytes employing the heat stable hemolysin produced by pseudomonas aeruginosa. using parasites isolated by this method, the presence of a parasite specific hexokinase has been demonstrated, providing an explanation for the increased glucose consumption observed with infected cells. enzyme assays and serology were employed in determining the purity and yield of purified para ...1979376819
2-acetylpyridine thiosemicarbazones. 1. a new class of potential antimalarial agents.based on the antimalarial properties observed for 2-acetylpyridine 4-phenyl-3-thiosemicarbazone (1), an extensive series of related thiosemicarbazones was prepared and tested against plasmodium berghei in mice. screening results indicated that the presence of the 2-pyridylethylidene group was critical and that certain phenyl, benzyl, phenethyl, or cycloalkyl groups at n4 of the thiosemicarbazone moiety also contribute to antimalarial activity.1979376848
dipeptides of o-methyl-l-threonine as potential antimalarials.l-leucyl-o-methyl-l-threonine, o-methyl-l-threonyl-l-leucine, and o-methyl-l-threonyl-o-methyl-l-threonine were prepared and compared with o-methyl-l-threonine and l-leucine for antimalarial activity against plasmodium berghei in mice. o-methyl-l-threonine significantly prolonged survival time at doses of 160, 320, and 640 mg/kg. o-methyl-l-threonyl-o-methyl-l-threonine was less active, significantly prolonging survival time only at 640 mg/kg. l-leucine, as well as the other two dipeptides, exhi ...1979376849
