chloroquine-resistant falciparum malaria in east kalimantan, indonesia.	following the discovery of four imported chloroquine-resistant p. falciparum infections in the province of yogyakarta (island of java) sensitivity tests were carried out in the province of east kalimantan island of borneo). twenty subjects were given 25 mg. of chloroquine base per kilogram of body weight over three days. two infections were found resistant at the rii level and a third at the ri level with early recrudescence on day 7. in the other 17 cases followed up to day 21, six were found a ...	1976	772235

histamine changes in plasmodium falciparum malaria.	histamine, serum complement factor 3 (c'3) and platelets were studied in 33 plasmodium falciparum patients. elevation of histamine level in the blood was found during acute infection but was more marked in the group of patients with systemic complications. a correlation between histamine changes, clinical complications, reduction of c'3 and degree of thrombocytopenia was observed. the possible role of histamine in the development of complications in p. falciparum infection and the possible relea ...	1976	772896
a new look at the protection of hemoglobin as and ac genotypes against plasmodium falciparum infection: a census tract approach.	a total of 4,097 randomly selected children under 5 years in accra, ghana were investigated for hb type, malarial parasite species, and parasite density. even though malarial infection rates in this metropolitan population were lower as compared to holoendemic areas, the differential survival of hb s carriers was confirmed. in addition, similar but less pronounced survival effects were seen in hb c heterozygotes. hb s carriers had the highest infection rates. more females than males were infecte ...	1976	773175

quinine disposition during malaria and during induced fever.	quinine disposition was studied in 5 subjects before and during an experimentally induced infection with a chloroquine-resistant strain of plasmodium falciparum and in 2 individuals before and during artificially induced fever. plasma quinine levels were determined by both a benzene extraction method (qb), which measures principally unmetabolized quinine, and a metaphosphoric acid precipitation method (qmpa), which measures quinine and quinine metabolites. the ratio qb/qmpa in plasma was used to ...	1976	773582
chloroquine-resistant falciparum malaria from irian jaya (indonesian new guinea).	a strain of plasmodium falciparum, transmitted in irian jaya (indonesian new guinea) was isolated in 1974 and sent to the university of maryland for characterization in nonimmune volunteers. at maryland the indonesia (whit.) strain, as it has been designated, was transmitted to colonized anopheles stephensi. prophylactically, it was not suppressed by proguanil hydrochloride 100 mg. daily. curatively, parasitaemia was not cleared by treatment with 1-5 g.

preliminary studies on the response of plasmodium falciparum to chloroquine in the philippines, with the in vitro technique.	previous investigations had shown that resistance to standard regimens of chloroquine occurred in some cases of falciparum infection in the philippines. more extensive investigations into this phenomenon were planned by the malaria eradication service, by means of the in vitro technique developed by rieckmann, in order to determine both the distribution of resistant strains throughout the country and their local incidence. before these studies were undertaken, a series of observations were made ...	1976	791531

clinical and laboratory presentation of malaria: an analysis of one thousand subjects with malaria parasitaemia.	in the context of this study the ethnic origin of the patients revealed no noteworthy difference in the clinical reaction to the parasite; neither did age or sex of the patients. any minor differences whcih appeared in length of history before seeking treatment and frequency of repeat attacks were more a reflection of the cultural pattern of response to illness (i.e. resort to traditional medicines) and the distance between the patient's home and the doctor rather than any altered response on th ...	1976	794512
jaundice and hepatomegaly in primary malaria.	the hepatic manifestations were studied in 65 patients having uncomplicated primary attacks of vivax and falciparum malaria. hepatomegaly due to a "non-specific reactive hepatitis" occurred in 57% of cases. jaundice occurred in 15% of patients and was invariably associated with hepatomegaly. the clinical syndromes of jaundice and hepatomegaly in uncomplicated primary attacks of malaria have to be distinguished from those related to disorders like viral hepatitis, hepatic amoebiasis, typhoid hepa ...	1976	794514

infectivity of falciparum malaria patients for anopheline mosquitoes before and after chloroquine treatment.	the infectivity of 25 falciparum malaria patients for anopheles balabacensis and anopheles minimus, before and after chloroquine therapy, was studied in central thailand. the proportion of patients infective for these mosquitoes was not affected by the administration of chloroquine, however, an elevation was observed in the median values for the numbers of oocysts on the guts of the a. balabacensis, but not the a. minimus, fed on infective patients after initiation of treatment.	1976	795104
precipitating antibody response to malarial s-antigens.	the gel diffusion test has been used to detect antibodies to malarial s-antigens. sera were obtained from entire gambian village communities, from young children with acute p. falciparum malaria, from children convalescent from such infections and from immune adults. in community studies, small selections of s-antigens detected antibody frequently in sera from older persons but rarely in sera from young children. larger panels of antigens detected antibodies in sera from half of 50 malarious chi ...	1976	795105

malarial antibodies measured by the indirect hemagglutination test in west african children.	the indirect hemagglutination test with plasmodium falciparum antigen was used to measure malarial antibodies in filter paper blood specimens from 527 west african children. a slight decline in antibodies was noted in 6- to 8-month-old children wh o had no malaria parasites in their blood smears. children older than 10 months had similar antibody levels regardless of the presence or absence of demonstrated parasites in blood smears.	1976	769576

malaria in the republic of the philippines. a review.	malaria in the republic of the philippines is caused principally by p. falciparum and p. vivax, with the former as predominant species. p. malariae is occasionally reported, while p. ovale is very rare and has been reported only in the island of palawan. malaria is widespread in distribution with prevalence varying from one area to the other. in 1970, the malaria morbidity rate was reported to be 77.6 per 100,000 while the mortality rate was 1.8 per 100,000. case detection activities revealed th ...	1977	21558
in vitro cultivation of the sporogonic stages of plasmodium: a review.	complete and continuous in vitro development of the sporogonic stages of the malarial parasite has not yet been accomplished, although success with erythrocytic stages (falciparum malaria) and exoerythrocytic stages (avian malaria) has been achieved. this lag in progress appears to be due to several inherent differences between sporogony and these other sequences of development. the trager-jensen system for in vitro development of erythrocytic stages of plasmodium falciparum results in the forma ...	1977	22406
