Potential modulation pancreas gland activity in hyperprolactimic male Rats ( Rattus norvegicus) by vitamin D3 treatment
Hyperprolactinemia status is commonly known as abnormal levels of prolactin hormone in
the blood due to endocrine disorder. So far, there is no evidence explaining whether
hyperprolactinemia affected Pancreas gland and vitamin D level in male. Therefore, this study aimed
to eliminate hyperprolactinemia affecting the Pancreas gland by treating it with vitamin D
supplements. Eighteen male rats were equally divide into three groups: The first group (6 rats):
received normal saline for 42 days. The second group (6 rats): rats were given 5 mg/kg
metoclopramide by intraperitoneal injection for hyperprolactinemia induction for 14 days. The third
group (6 rats): hyperprolactinemic rats received 2.5 mg/kg vitamin D3 for 28 days.
After the end of experimental) 42days(,hormonal parameters (prolactin, insulin, and vitamin D3)
were measure, and the Pancreas gland was remove for routine paraffin-embedded section staining
with hematoxylin and eosin staining. The result of the study revealed a significant decrease (P≤0. 01)
in prolactin hormone concentration and a significant increase (P≤0. 01) in D3 concentration and
insulin hormone Group 3compared with Group2. Histological examination of parts of the pancreas
gland treated with vitamin D showed a remarkable recovery in the size and number of cells, and the
cells became abundant in the cytoplasm. It was also noted that the nuclei returned to a size close to
normal and took on a regular, spherical shape and central location compared to the
hyperprolactinemia group. The study concluded that vitamin D had a protective effect on Pancreas
gland by stabilizing insulin hormone level and restoration histological architectures throughout
