Antimalarial activity of methanolic extracts from plants used in Kenyan ethnomedicine and their interactions with chloroquine (CQ) against a CQ-tolerant rodent parasite, in mice.
TLDR
Plants, which showed significant antimalarial activity including Vernonia lasiopus, Toddalia asiatica, Ficus sur, Rhamnus prinoides and RhamNus staddo warrant further evaluation in the search for novel antimalaria agents against drug-resistant malaria. Expand
Antiplasmodial triterpenoids from Ekebergia capensis.
TLDR
Ten new triterpenoid compounds isolated from the stem bark of Ekebergia capensis were found to exhibit moderate antiplasmodial activity and were screened in vitro against both chloroquine (CQ)-sensitive and -resistant Plasmodium falciparum isolates. Expand
Mitigation of caffeine-induced teratogenicity in mice by prior chronic caffeine ingestion.
Pregnant A/J female mice, which had drunk tap water or a 0.05% caffeine solution for 8-19 weeks after weaning, were each injected sc with 150 or 250 mg/kg caffeine once on day 13 of gestation. AfterExpand
A brief survey of free-living amebae in Thailand and Hamamatsu District, Japan.
TLDR
This study found that soil samples of Hamamatsu district, Japan have significantly higher levels of Acanthameba and Hartmannella than those of Thailand which each of them caused death in mice, serving as additional evidence for the presence of free-living amebae under natural and the difference in distribution between tropic and subtropic areas.

Characterization of subtypes of gamma-aminobutyric acid receptors in an Ascaris muscle preparation by binding assay and binding of PF1022A, a new anthelmintic, on the receptors
TLDR
It is conclusive that PF1022A bound with GABA receptors, and a direct effect of PF 1022A on GABA receptors can thus be postulated. Expand
Studies on chemotherapy of parasitic helminths (VII). Effects of various cholinergic agents on the motility of Angiostrongylus cantonensis.
TLDR
It is suggested that the excitatory cholinergic mechanism in A. cantonensis is nicotinic, and it is basically similar to that reported in Ascaris suum. Expand
Studies on chemotherapy of parasitic helminths: effects of avermectin B1a on Angiostrongylus cantonensis in rats.
TLDR
No direct vermicidal effect was observed in this treatment of avermectin Bla against Angiostrongylus cantonensis in rats, because there was no significant difference in the recovery rate of worms from that of control rats. Expand
Differential rapid analysis of ascorbic acid and ascorbic acid 2-sulfate by dinitrophenylhydrazine method.
TLDR
The differential oxidation of AA and AAS with 2, 6-dinitrophenolindophenol (2,6-Dye) and KBrO 3 and the determination of the osazone produced with the original method by Roe and Kuether are concerned. Expand
Angiostrongylus cantonensis: paralysis due to avermectin B1a and ivermectin.
TLDR
The results suggest that a gabergic mechanism is involved in the paralyzing action of ivermectin, as well as avermECTin B1a, in A. cantonensis. Expand
