Activity of superoxide dismutase obtained from senile cataract lens - effect of diabetes mellitus.

The activity of Cu,Zn superoxide dismutase in the fluid obtained from eye lens capsules after cataract surgery was investigated in samples obtained from patients with senile cataract and with senile cataract combined with diabetes mellitus. Two parameters were measured and compared: the frequency of occurrence of detected superoxide dismutase activity and the relative activity of the enzyme in samples derived from senile cataract patients versus those from the patients affected additionally by diabetes mellitus. It was confirmed that the decrease of superoxide dismutase activity during cataract was additionally promoted by diabetes mellitus.

[Coexistence of unilateral retinoblastoma and Leber-Coats's disease in contralateral eye-case report].

Purpose: A case report of retinoblastoma and Leber-Coats' disease coexistence--two diseases which are very dangerous to the organ of vision.

[Immunologic tests in patients with idiopathic uveitis--preliminary reports].

Aim: This study aimed to evaluate the immune system function in patients with uveitis of unknown aetiology.

Methods: The clinical material comprised 19 patients with endogenous uveitis. In all cases the following immunological tests were performed: serum immunoglobulins A, G, M, total IgE, circulating immune complexes, complement components C3c and C4-all determined by laser nephelometry; antinuclear antibodies assessed with indirect immunofluorescence method using HEp-2 cell lines; and antineutrophil cytoplasmic antibodies using indirect immunofluorescence test.

[Long-term observations of ocular toxocariasis in children and youth].

Purpose: To evaluate the clinical status and ELISA test changes in a group of children with ocular toxocariasis.

Methods: We enrolled 37 patients in the studies. The follow-up period lasted at least 3 years (3-15 years) after the diagnosis had been established.

[Use of cryopexy in treatment of retinoblastoma].

Unlabelled: The aim of this work is to present our own experience in the treatment of retinoblastoma with cryopexy.

Material And Methods: 24 children were observed, among whom 23 had bilateral and 1 unilateral retinoblastoma. We applied transconjunctival cryopexy to small neoplasmatic foci in retina located anterior to the equator.
