[CHARACTERISTICS OF THE RETINA IN CHRONIC STRESS IN LABORATORY RATS OF DIFFERENT AGE GROUPS].

The retina was studied in albino laboratory male rats of two age groups (12 and 24 months), 10 animals in each subjected to chronic combined stress. The stress was caused in animals by simultaneous exposure to pulsed light, loud sound, swinging and restriction of mobility for 7 days, 30 mm daily. The retina of intact rats of the corresponding age groups (n = 20) served as control.

[Differential diagnosis of thyrotoxicosis in subjects with post-immunization reaction].

An increasingly greater fraction of the general population is getting involved in the immunization program. However, conditions of individual subjects are not always properly evaluated prior to immunization. The clinical case reported below demonstrates the difficulty of diagnostic examination of patients with Graves disease (toxic goiter), endocrine ophthalmopathy, and post-immunization reaction.
