[Manifestations of visceral and ocular symptoms of toxocariasis in a 6-year-old boy].

In the past 10 years we have examined 137 cases of toxocariasis, predominantly in children. Three cases were with unilateral ocular involvement. The article reviews a 6-year-old boy with left side strabismus and granulomatous chorioretinitis. Laboratory examinations revealed blood eosinophylia 24% and IgG against Toxocara canis larvae in titer 1:320 by indirect immunofluorescent assay. In epidemiologic anamnesis we concluded that about 4, 5-year-long geophagia was the source of infection.

Apoptosis and free radicals.

Free radicals that appear during physiological processes may lead to apoptosis in some pathological conditions when antioxidant capacity of the tissue is surpassed. Additionally, free radicals are involved in the control of apoptosis; antioxidant agents suppress apoptosis induced by a variety of stimuli. The possibility that apoptosis is regulated by modulation of the levels of free radicals is discussed.

Apoptosis II: Apoptosis in the pathogenesis and treatment of diseases.

This review presents the implications of abnormal regulation of apoptosis in the pathogenesis of a variety of diseases, some of them characterized by a failure of cells to undergo apoptosis, and the others characterized by cell loss. The new perspectives in the therapy of such diseases by developing therapeutic agents that increase or decrease the susceptibility of particular cells to apoptosis are also reviewed.
