RESUMO
Twenty four female rats divided into two groups [each group consists of twelve rats] were used in this study in a real exposure experiment in the point of maximum field of the cellular base station radiation field. Five epidural electrodes were implanted in the skull of the first group of rats, two in the frontal region [right and left hemispheres], two in the occipital region [right and left hemispheres], and one in a reference point in the nose. The first group was exposed to microwave radiation and EEG was recorded weekly [monoplolar and bipolar] on the same day and at same time of week for eight weeks. The rats of the second group were exposed at the same place of the maximum field intensity as the first group, and the neurotransmitter serotonin was assayed weekly
RESUMO
Among 20,124 primary school children examined in the various primary schools in the Eastern district of Mansoura. We found 202 cases of Manifest Concomitant squint [2%]. The highest frequency of squint was at the age of six years [40.1%] and the incidence decreases during the school life to [7.9%] at the age of 12 years. The commonest type of deviation was the convergent type representing 84.1 of all cases. There is no significant difference between girls and boys in this work, as we found that the boys 102 [50.5%] and girls 100 [49.5%]. Most of the case with convergent squint were hypermetropic of moderate degree ranging from + 2.5 D. to 4.0 D. whereas in divergent squint 12 cases were hypermetropic and 20 cases were myopic
