[Lymphocyte transformation in allergy to penicillin]. / Transformación linfocitaria en alergia a la penicilina.

Thirty patients both sexes with ages between 1-52 years old, thinking that they are allergic to penicillin, were studied because they were found to have some clinic symptoms immediately after the administration of penicillin procain I.M. (intramuscle) such as urticaria, angioedema, anaphylactic shock and Stevens-Johnson syndrome. In order to confirm or to discard this asseveration an in-vitro lymphocyte transformation test was realized, with the venous peripherical blood of each patient, using the greater determinative of penicillin: the peniciloil. The results obtained were twelve negatives, twelve on doubt and six positives. These results show that the in-vitro lymphocyte transformation test may be useful to decide, when a patient could be considered allergic or not to penicillin.

[Immunological status of patients with amebic hepatic abscess]. / Estado inmunológico en pacientes con absceso hepático amibiano

The authors studied 10 cases of amoebic hepatic abscess documented by clinical evidence and confirmed by laboratory tests, liver scan and a good response to treatment. The immunological state of the patients was determined by protein electrophoresis, immunoelectrophoresis, counter-immunoelectrophoresis, radial immunodiffusion and roset formation for T and B lymphocytes. It is concluded that the alterations of cellular and humoral immunity is evident in cases of amoebic hepatic abscess; this alterations are more clear in the acute form of the illness and the immunological deficiency is more significant in the celular immunity.
