[Analysis of retinal vein motion in glaucoma patients].

Background: Analysis of retinal vein amplitude in eyes of glaucoma patients.

Patients And Methods: Motion of retinal veins was captured by Retinal Vessel Analyzer in duration of 30 seconds. Inferotemporal vein segments of 500 micrometers length in the immediate vicinity of, as well as away from the optic disc were chosen.

Rigidity of retinal vessel in untreated eyes of normal tension primary open-angle glaucoma patients.

Background: To analyze pulse wave propagation in the ocular circulation and vessel stiffness in untreated eyes of normal tension primary open-angle glaucoma (NTG) patients.

Methods: Inferotemporal retinal vessels of 22 NTG eyes and 25 controls were examined with a Retinal Vessel Analyzer. Inferotemporal peripapillary retinal nerve fiber layer thickness was measured by ocular coherence tomography.

Species-specific field testing of Entamoeba spp. in an area of high endemicity.

Entamoeba histolytica has been separated in recent years into 2 morphologically identical species: the apathogenic E. dispar and the pathogenic E. histolytica, only the latter being pathogenic.

Humoral immune responses during a malaria vaccine trial in Tanzanian infants.

The development of a malaria vaccine is a priority for improved and sustained malaria control. Optimal use of a vaccine in Africa will only be achieved if it can be delivered through the Expanded Programme of Immunization (EPI). We have completed a trial of the peptide vaccine SPf66 in Tanzanian infants, given alongside the EPI vaccines.

Analysis of Plasmodium falciparum infections in a village community in Northern Nigeria: determination of msp2 genotypes and parasite-specific IgG responses.

The genetic diversity of P. falciparum and multiplicity of infection has been studied in a village in Northern Nigeria at the end of the rainy season, when transmission is high. We analysed blood samples from 104 individuals aged 5-70 years by polymerase chain reaction (PCR) amplifying the gene for the merozoite surface protein MSP2 followed by genotyping based on restriction fragment length polymorphism (RFLP).

Immune responses to Plasmodium falciparum antigens during a malaria vaccine trial in Tanzanian children.

Among Tanzanian children living in an area of intense and perennial malaria transmission, prevalence of naturally acquired IgG antibodies that recognize SPf66, NANP, p190 and a 19 kDa fragment of the merozoite surface protein-1 (MSP-1) is high and increases with age. This possibly reflects the high level of natural exposure of the children to P. falciparum.

Thiabendazole vs. albendazole in treatment of toxocariasis: a clinical trial.

Between 1986 and 1988, 34 patients (age range six to 83 years) with visceral or ocular larva migrans were randomly assigned to a five-day treatment with thiabendazole 2 x 25 mg kg-1 day-1 (15 patients) or albendazole 2 x 5 mg kg-1 day-1 (19 patients). On the fifth treatment day, six patients (40%) in the thiabendazole group and 11 patients (58%) in the albendazole group showed excellent or good drug tolerability. Efficacy of treatment was assessed after 30 weeks (range six to 56 weeks).
