RESUMO
Diagnosis of the human cyclosporiasis is reported in São Paulo, SP, Brasil. Cyclospora cayetanensis has been identified in the feces of a patient by a modified Kinyoun staining method, with later sporulation in a solution of 2.5% potassium dichromate. The probability that this parasite is the eventual cause of gastrointestinal disturbances in the country was stimulated by this finding, which was arrived at by a simple technique. It had been kept in mind that the disease was expressing itself mainly among immunocompromised patients, whose number is increasing; especially in those with acquired immunodeficiency syndrome (AIDS), which is caused by the human immunodeficiency virus (HIV).

Quantative histochemical analysis of nerve degeneration in rats from zero to 192 hours was studied utilizing both Schiff reagent and PAS reaction. In addition, amylase digestion prior to PAS staining and aniline blockade of Schiff reactivity were employed. The staining intensity of all the reaction was measured histophotometrically and the mean optical density (OD) was determined for the following time intervals: 0, 24, 48, 96, and 192 hours.
