Further investigations of glucose-6-phosphate dehydrogenase variants in Flores Island, eastern Indonesia.

We conducted field surveys for malaria and glucose-6-phosphate dehydrogenase (G6PD) deficiency in the eastern part of Flores Island, East Nusa Tenggara Province, Indonesia. A total of 1,108 volunteers (642 males and 466 females) belonging to three ethnic groups (Sikka, Ende and Bajo) were examined, and 55 G6PD-deficient individuals (38 males and 17 females) were detected. Among them, 50 samples were analyzed molecularly, in addition to three deficient cases in a Bajo family.

Five different glucose-6-phophate [correction phosphate]dehydrogenase (G6PD) variants found among 11 G6PD-deficient persons in Flores Island, Indonesia.

We conducted a survey for malaria diagnosis and treatment in four primary schools in Flores Island, one of the Indonesian Islands with an area of 17000 km(2) and a population of 1.8 million. Of those examined, 24.

Synergistic enhancement of a copper chelator, bathocuproine disulphonate, and cysteine on in vitro growth of Plasmodium falciparum in glucose-6-phosphate dehydrogenase-deficient erythrocytes.

In vitro growth of Plasmodium falciparum is restricted in glucose-6-phosphate dehydrogenase (G6PD)-deficient erythrocytes (RBC), as a result of oxidative stress. Bathocuproine disulphonate (BCS), a copper chelator, as well as cysteine have been shown to synergistically stimulate the in vitro growth of various mammalian cells and Trypanosoma under oxygenated conditions. We examined the effects of these two chemicals on the in vitro growth of P.
