[Evaluation of Plasmodium falciparum antigen of human origin using indirect immunofluorescence reaction in malaria].

The authors point out the use of P. falciparum antigens from man in the Malaria IFA test. In Malaria areas it is very easy to find them and although they are "coated" by antibodies they are quite valuable in significant titers.

[Immunocyte adherence and leukocyte migration inhibition tests in dogs infested with Leishmania donovani. Importance of lymphocyte conservation in liquid nitrogen].

A method of canine lymphocytes isolation and storage in liquid azote with DMSO is described. It was possible to use these lymphocytes in the immunocytoadherence and leucocytes migration inhibition tests in dogs infected with Leishmania donovani. The sensitisation was made with a soluble antigen from promastigotes of L.

[Bioclinical study of the electro-immunodiffusion technic for the assay of serum alpha fetoprotein].

The author discusses the result that may be expected in clinical medicine from an electro-immunodiffusion method for the detection of alpha-foetoprotein. The samples studied were obtained from pregnant women, patients with liver cell carcinoma or severe digestive diseases, whether malignant or not, and a few amniotic fluids and sera obtained from the umbilical cord. This simple, rapid method is characterized by a sensitivity threshold of about 300 ng/ml and permits one to detect about 75% of cases of liver cell carcinoma.
