چکیده

The radiant energy incident on the retina of a human viewing: the noon-day sun is calculated as 4.25 cal./cm.'-'-sec. with an image diameter of 0.16 mm., assuming an atmospheric transmission of 85'/( and a pupil diameter of 2.6 mm. The retinal irradiance under the limiting conditions of 100% atmospheric transmission and 6 mm. pupil diameter is shown to be only 29 cal./cm.-'-sec. This retinal irradiance is compared to experimentally determined retinal burn thresholds in rabbits. It is concluded that eclipse burns, which are known to occur, would not be predicted on the basis of extrapolated animal data, and that care must be exercised in using existing animal threshold data in predicting chorioretinal damage in humans.

اثرات تجویز هورمون رشد بر دانسیته استخوانی در خرگوش بالغ سالم

Background: The effects of growth hormone (GH) on bone density in healthy adults is controversial. This study was performed to evaluate the effects of GH administration on bone density under controlled conditions in healthy adult rabbits. Methods: Twenty healthy adult New Zealand white rabbits of both sexes were included in the study. The rabbits were divided into two groups. The experiment gr...

Determination of hair loss (alopecia) cause and effective treatment in laboratory rabbits

In number (16 of 22) of infants in the Dutch laboratory rabbit breeding colony, in aged 45-65 days old, hair loss (alopecia) seen at the top of the head and around a week after the hair fall, was created in a state of complete alopecia. For determination of the cause of hair loss, after the observation and palpation the alopecic area, there have not been any swelling, abscesses, tumors. In skin...

Protective Effects of α-Tocopherol on ABR Threshold Shift in Rabbits Exposed to Noise and Carbon Monoxide

Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...
