ABSTRACT Thyroiditis was induced in Sprague-Dawley rats by repeated immunization with thyroid extract and Freund's adjuvant. Immunized and control animals were killed at intervals up to 6 hours after intravenous administration of 131I as iodide at 5, 8 and 10 weeks after the first injection. Radioiodinated compounds in the thyroid glands were identified chromatographically. Evidence of moderate thyroiditis was present (histologic appearance, gland weight, and protein-bound iodine-butanol-extractable iodine difference) but the rate of incorporation of radioiodide into thyroxine, the percentage of radioactivity in the gland as iodide, and the MIT/DIT ratio were not significantly different in immunized and control animals. The MIT/DIT ratio was found to vary with time after 131I administration in both immunized and control animals. These studies did not uncover a defect in organification of iodide in experimental thyroiditis similar to that described by others in humans with Hashimoto's thyroiditis.

Abstract Background Plant extracts are effectively acting as the natural medicinal cocktail, non-side effective, efficacious, and freely available. The present study aimed to unveil the pharmacological and medicinal effects of Terminalia chebula plant extract in 7,12-dimethylbenzanthracene (DMBA)-induced mammary carcinoma in Sprague Dawley rats. The plant extract obtained was subjected to in vivo antioxidant and anticancer studies in various concentrations after an analytical technique such as FTIR, GCMS, and HPLC-based chemo-profiling in Sprague Dawley rats. Results Apart from the antiproliferative effect on breast cancer cell line (MCF-7) and normal breast epithelial cells (MCF-10a), we have measured the changes in body weight, along with other tumor parameters such as tumor volume, tumor incidence, tumor weight, tumor burden, serum biochemical parameters, and histopathological findings of breast tissue. As the oxidative stress further enhances the development of cancer, the antioxidant property of the plant extract demonstrates its use against cancer treatment. One hundred fifty milligrams per milliliter (IC50 250 μg/mL) concentration of the ethanolic extract was vital for the proliferation of MCF-7 cell lines (Fig. 7a). Meanwhile, 300 μg/mL (IC50 150 μg/mL) was an effective dose to attain a maximum HDAC inhibition of 78%. Also, the normal liver and kidney functioning revealed the non-toxicity nature of the plant. Conclusion Terminalia chebula could be one of the effective naturally obtained anti-breast cancer medications. Isolation and characterization of individual bioactive compounds of T. chebula would be the future perspective.

A herbal preparation, Shemamruthaa (SM), was formulated to investigate the molecular mechanism by which it exhibits anticancer effects in mammary carcinoma bearing rats. Female Sprague-Dawley rats were used for the study, and mammary carcinoma was induced by administration of 7,12-dimethylbenz( a)anthracene, intragastrically. After 3 months of induction period, the rats were treated with SM (400 mg/kg body weight) for 14 days. Our study shows that SM-treated mammary carcinoma rats showed regression in tumor volume with concomitant increase in p53, Bax, caspase-3, and caspase-9 mRNA and protein levels compared with mammary carcinoma–induced rats. Proliferating cell nuclear antigen and anti-apoptotic Bcl-2 were markedly increased in mammary carcinoma–induced rats, whereas the SM treatment significantly decreased the expression of these proteins. The expression pattern of apoptotic signaling molecules analyzed in the present study signifies the therapeutic efficacy of SM against breast cancer.
