a quinoline methanol (wr 30090) for treatment of acute malaria.wr 30090 at a dose of 230 mg every 8 hr for 6 days has proven to be a safe, well-tolerated compound with photosensitivity proving to be a minor consideration. wr 30090 was found to be an effective medication for the treatment of acute malaria caused by several strains of plasmodium falciparum. at the dose of 230 mg every 8 hr for 6 days, all of six men infected with a chloroquine-susceptible strain (uganda i) were cured, all of 13 subjects infected with moderately chloroquine-resistant strains ( ...19734597715
prophylactic activity of a phenanthrene methanol (wr 33063) and a quinoline methanol (wr 30090) in human malaria.wr 33063 (3-bromo-10-[alpha-hydroxy-beta-(n, n-diheptylamino)ethyl]-phenanthrene hydrochloride) and wr 30090 (6,8-dichloro-2,3,4-dichlorphenyl-di-n-butylaminoethyl-4- quinolinemethanol hydrochloride) were tested for suppressive prophylactic effect on induced malaria in nonimmune volunteers living in an area where malaria is not naturally transmitted. doses of 800 mg of wr 33063 and 690 or 460 mg of wr 30090 were given at weekly intervals to men exposed on the day of the first dose to mosquitoes ...19734597716
treatment of falciparum malaria from vietnam with a phenanthrene methanol (wr 33063) and a quinoline methanol (wr 30090).two new investigational antimalarial drugs developed by the u.s. army malaria research program were tested in patients with multi-drug-resistant falciparum malaria from vietnam. wr 33063, a phenanthrene methanol, cured 13 patients treated in the united states. all of these patients had suffered multiple recrudescences after treatment with standard antimalarial drugs. in addition, 23 of 25 patients with acute attacks of falciparum malaria treated in vietnam were cured. the rate of clinical respon ...19734597717
sulfalene with pyrimethamine and chloroquine with pyrimethamine in single-dose treatment of plasmodium falciparum infections. a trial in a rural population in northern nigeria.a comparative trial was carried out in northern nigeria of the ability of the drug combinations chloroquine-pyrimethamine and sulfalene-pyrimethamine to clear the peripheral blood stream of asexual forms of p. falciparum within 7 days. the reappearance of asexual p. falciparum forms within the 70-day follow-up period and the occurrence of vomiting during the 2-3 hours following administration of the drugs were also recorded. the purpose of the trial was to choose the more suitable of the two dru ...19734603037

identification of malaria parasites by fluorescence microscopy and acridine orange staining.the need for a technique that is more sensitive than the use of romanowsky-stained thick blood films for detecting malaria parasites at low concentration in the blood is well recognized. one of the more promising methods appeared to be fluorochrome staining with acridine orange. however, reports on the efficacy of the technique were contradictory and it was not clear to what extent blood films taken under survey conditions would contain fluorescing artefacts that might confuse diagnosis. an inve ...19734130021
enzyme typing of malaria parasites.analysis of various isolates of plasmodium falciparum from east and west africa and from south-east asia showed that some of the parasite enzymes can exist in more than one electrophoretic form. at least one form of each enzyme was common to parasites from all three regions. the enzyme forms could be used to differentiate morphologically indistinguishable samples of p. falciparum.19734196338

comparison of indirect haemagglutination and immunofluorescence tests for malaria antibody in aotus monkeys infected with plasmodium falciparum. application of indirect haemagglutination tests for malaria.longitudinal observations were made on 6 aotus monkeys repeatedly infected with plasmodium falciparum (west african and palo alto strains). immunofluorescence titres were higher than indirect haemagglutination titres in the primary phase of the infections. both serological tests were consistently positive later in the infections. precipitins were often not detectable even during episodes of parasitaemia.19734211057
application of the indirect haemagglutination test for malaria: reproducibility with plasmodium falciparum-sensitized cells.the reproducibility of the iha test was assessed. two batches of glutaraldehyde-fixed sheep cells were used and the cells were sensitized with different batches of p. falciparum antigen obtained from 4 owl monkeys. at the individual level the iha test appears to have a reproducibility of approximately 90%.19734211058

immunopathology of malaria.antibodies with different spectra of reactivity are produced during malarial infections and marked changes in igg and igm levels occur. in addition malaria elicits serological changes that are usually associated with connective tissue disease. the excessive anaemia associated with malaria may, in part, be an autoimmune phenomenon. transient nephritis accompanies many plasmodial infections but chronic malarial nephrotic syndrome is specifically associated with quartan malaria. malarial infection ...19744216408
prospects for vaccination against malaria in man.rodents have been successfully protected against a challenge of viable plasmodium berghei by employing as vaccine: (1) the irradiated blood stages of the same parasite, or (2) the water-insoluble fraction of the blood stages, or (3) irradiated sporozoites; all these vaccines were shown to be stage-specific. a method is outlined for testing in the field, in the absence of any risks, the efficacy of analogous vaccines against falciparum malaria in man. it is emphasized that: (1) the efficacy of th ...19744216411

early diagnosis and clinical picture of malaria.as a result of extensive travel and temporary residence by people in areas where malaria is endemic, the disease is being reimported into countries from which it has been eradicated. owing to the lack of experience of malaria on the part of present-day physicians and the atypical presentation of some forms of the disease, it is not always recognized, which in the case of falciparum malaria may have grave consequences. in every case of an unexplained fever the possibility of malaria should be tak ...19744613500

clinical testing of new antimalarial compounds.more than 200 000 chemical compounds have been screened for antimalarial activity over the past 10 years by the us army antimalarial drug development program. by means of extensive animal testing, 26 of these compounds were selected for clinical study in human subjects volunteering for such trials. of these, 7 have received complete clinical trials and are in various stages of field evaluation, 4 are currently undergoing clinical trial, and 2 are still awaiting testing in volunteer subjects. thu ...19744613503
antifolic combinations in the treatment of malaria.for the treatment of malaria, combinations of drugs with antifolic action have the great advantage, compared with other drug associations, of synergic action, which increases the effectiveness of the preparation, limits its toxicity, and reduces the risk of resistance. the associations of a sulfonamide (sulfalene, s) with a diaminopyrimidine derivative (pyrimethamine, p, or trimethoprim, t) have given good immediate clinical results. an analysis of the pharmacodynamic and pharmacokinetic charact ...19744613504
treatment of drug-resistant malaria in man.the progressive spread in asia and south america of falciparum malaria resistant to 4-aminoquinolines, and the focal occurrence in all malarious regions of infections resistant to dihydrofolate dehydrogenase inhibitors such as pyrimethamine and proguanil, make it everywhere necessary to be alert to the failure of accepted curative, prophylactic, or sporontocidal chemotherapeutic agents. resistance to 4-aminoquinolines may be met curatively with courses of treatment lasting 1-14 days, or more, th ...19744613507
mechanisms of acquired immunity and epidemiological patterns of antibody responses in malaria in man.this paper considers the participation of macrophages, thymus-dependent lymphocytes (t-cells), and thymus-independent lymphocytes (b-cells) in man's immune response to malaria. although phagocytosis by macrophages is an important feature of malaria the full extent of cooperation between these cells and t- and b-cells is not known. evidence that t-cells play an important defensive role is at present unconvincing. b-cells on the other hand function importantly in the synthesis of immunoglobulins a ...19744613508
imported malaria.there have been 4 waves of imported malaria in the usa. they occurred during the colonization of the country and during the second world war, the un police action in korea, and the viet-nam conflict. the first 3 episodes are briefly described and the data on imported malaria from viet-nam are discussed in detail.endemic malaria is resurgent in many tropical countries and international travel is also on the rise. this increases the likelihood of malaria being imported from an endemic area and int ...19744613510
a malaria model tested in the african savannah.a new mathematical model of malaria has been developed for comparing the effects of alternative control measures. it describes both the temporal changes of the p. falciparum infection rate and the immunity level of the population as a function of the dynamics and characteristics of the vector populations, which are summarized in the concept of vectorial capacity. a critical vectorial capacity is specified, below which malaria cannot maintain itself at an endemic level. the model has been tested ...19744613512
