The aim of this study was to determine the effects of supplemental
drinking boron on morphology of ostrich chicks’ cerebrum. Twenty four hatched
ostrich chicks were divided into six group (I-VI) and supplemented by the water
with 0, 40, 80, 160, 320 and 640 mg L-1 boron, respectively for 45
days. Cerebrums were obtained and weighed after dissection then measured the
transverse diameter, longitudinal diameter and height of cerebral hemisphere
immediately. Paraffin embedded sections of cerebral tissues (4 μm thick)
were stained with HE, Nissl’s and argentaffin and then micro photographed.
It showed significant increase (p<0.05 or p<0.01) in each anatomy index
of group IV in comparison with the other groups while group VI showed significant
decrease. Histology study showed that neurons of the cerebrum of group I and
II were alike, nerve fibers passed horizontally within the cortex. Neurons of
group III were varied in size and shape and with abundance of nerve fibers passed
horizontally within the cortex tighter. Whereas neurons of group IV had more
types than the rest of groups and were well arranged from the edge to inside
by size, the nerve fibers were rich and interweaved. In contrast, neurons of
group V and VI were monomorphic with less neurite and nerve fibers were tenuous
and sparse. Findings showed that 80-160 mg L-1 supplemental drinking
boron promotes cerebrum development, neurons differentiation, neurite formation
and nerve fibers elongation of the cerebrum of 0-45 days old ostrich chicks. |
