| Summary: | Twenty healthy adult Carp fish were collected from Dijlah river in Iraq in
Summer and winter times of the year (Ten for each ). The fish were sacrificed and
fixed in 10% neutral buffered formalin solution. Routine histological preparations
were carried out. Hematoxylin - Eosin stain was used. The finding of the current study
showed that clear connective tissue capsule was not observed. Instead, wide loose
connective tissue was surrounded the follicles. The thyroid follicles were distributed
individually or in groups in the kidney and sub pharyngeal region( around the ventral
aorta). The thyroid tissue was represented by thyroid follicles of different sizes and
shapes. In Carp fish, the building up and organization of the follicular cells of thyroid
follicles were simple and poorly organized. There was a close relationship between
the morphological state of thyroid follicles and the season( temperature). The results
of the present study also demonstrated that the spread of thyroid follicles in summer
was more than in winter where the follicles appeared as aggregated at the periphery
of renal tissue and also the results of this study showed that large and small follicles
were combined. The study also registered that, during winter, the large follicles were
mostly formed by the aggregation of smaller ones and that according to the
physiological status of the thyroid tissue. The study concluded firstly that these
follicles had the ability to wandered within the renal tissue. Moreover, the study
concluded that the thyroid follicle was dynamic structure, and their sizes depending
on the amount of colloid present within . |
