“…Our previous studies have indicated the importance of the postnatal period in the development of the central nervous system [12][13][14][15]. In the postnatal periods in the rat CP as BCSFB continues to grow to reach its maturity [16], but the period of this maturation differs considerably among mammalian species [17].…”

Morphometric parameters of the lateral ventricle choroid plexus epithelial cells (average area, perimeter, bounding rectangle area, average nuclear area, nuclear perimeter, nuclear circularity and average nucleocytoplasmic ratio) were studied in postnatal and juvenile (10 th , 16 th and 38 th postnatal days) 15 male and 15 female rats. The results were statistically analyzed by factorial ANOVA.Mean values of epithelial cells area, bounding rectangle area and perimeter were signifi cantly higher in 16 days old, than in 10 and 38 days old rats. Opposite to this, the nucleocytoplasmic ratio was lower in the 16 days old, than in 10 and 38 days old rats. Average nuclear area and perimeter showed similar trends, while nuclear circularity increased from the 10 th to the 38 th day. Signifi cant sex differences were in the epithelial cells area, bounding rectangle area and perimeter, being higher in males than in females in both 16 and 38 days groups. Nucleocytoplasmic ratio was higher in 10 days old male rats, but lower in 16 and 38 days old male rats. Generally, choroid epithelial cells size increased on the 16 th and then decreased on the 38 th day, but still remained higher compared to the 10 th day. Nuclear size after increasing on day 16, also decreased on day 38, but to values lower than on day 10. The general decrease of nucleocytoplasmic ratio which accompanied these changes indirectly suggests a functional decrease. In the investigated period the male rat choroid epithelial cells were larger, but their nucleocytoplasmic ratio, which suggests the functional status, was lower than in females, indicating sex differences in the growth dynamics of the rat choroid plexus.

Background & Objective: Amygdal is a subcortical nucleus of limbic system that has a pivotal role in behavioral, vegetative and endocrine activities. Sexual dimporphism in some amygdale nuclei have been investigated. The aim of this study was to answer this query: does the total volume of amygdale nucleus differ in two sex morphometrically? Material & Methods: This study was conducted on Adult wistar rats (male and female N=10 per group, 8weeks old, weight 240-260 gr). Brains were removed and fixed in formalin 10% and in 10 µm sections were prepared by microtome. After staining with cresyl violet 1% the boundary of amygdal was defined and its volume calculated with cavalieri method Results: The volume of amygdala nucleus was estimated 2.07 ± 0.12mm3 in male rats and 1.57± 0.11 mm3 in female rats (P<0.05). Conclusion: Based on our finding the total volume of amygdala nucleus in male rats is larger than those of female rats that suggest the sexual dimorphism of amygdala nucleus between tow genders .These findings may have implications for developmental studies dimorphisms in human amygdala.
