Quantitative analysis of "synaptic" ribbon profiles in the pineal complex of male and female Pirbright-White guinea pigs.
1990
Previous studies have pointed in the direction of sex differences as well as regional differences in the pineal gland of guinea pigs. In the present investigation these aspects were studied at the electron-microscopic level by quantitating different types of “synaptic” bodies, intrinsic to pinealocytes. The two major types of “synaptic” organelles, ribbons and spherules, did not exhibit regional or sex differences. “Synaptic” structures intermediate in appearance to ribbons and spherules were significantly larger in number in males in the distal region of the pineal gland, compared to females. As previous studies have shown that ribbon and spherule numbers undergo characteristic changes dep…
Light exposure patterns in schizophrenia
1992
Spontaneous light exposure patterns were studied in 10 chronic schizophrenic patients. Half of our schizophrenic patients exposed themselves to bright light exceeding ordinary indoor illumination. There was a significant positive correlation between the percentage of exposure to bright light and the Brief Psychiatric Rating Scale subscore anergia and a significant negative correlation with depression.
