Abstract
This study was conducted to elucidate the effects of age and sex on the
histometrical values of blood pressure related organs including heart, kidneys
and adrenal glands in teddy goats. The hearts, kidneys and the adrenal glands of
36 teddy goats, divided in three age-groups; kids (6-12 months), adults (13-21
months) and adults (22-24 months), were processed for histometrical studies.
Mean diameters, volumes and Intramural connective tissue contents of right
atrium, left atrium, right ventricle and left ventricle were recorded from
cardiac specimens.
Age affected none of the parameters of the heart significantly. Mean diameters
and volumes of subcapsular and juxtamedullary glomeruli were recorded from
kidney specimens. All parameters of the kidney invariably showed a consistent
rise with advancing age. Thicknesses of
the zona glomerulosa, zona
fasciculata and zona reticularis
of the right adrenal gland were measured. Thickness of different zones of
the adrenal cortex showed significant (P<0.05) changes with age.
It is conceivable from these findings that the
development of heart, kidneys and adrenal showed an increase parallel to the
advancing age to adjust with the increasing blood pressure due to physiological
development process. Sex, however, played a secondary role.
