هدفت الدراسة الحالية الى معرفة بعض تاثيرات المستخلص المائي لنبات اللهانة ((Brassica oleracea على مستويات هرمونات الغدة الدرقية الثايرونين ثلاثي اليود Triiodothyronine (T3) والثايروكسين (Thyroxine (T4والهرمون المحفز للدرقية Thyroid stimulating hormone (TSH | The aim of the present study was to investigate some effects of the aqueous extract of cabbage (Brassica oleracea L) on the Thyroid hormones concentrations Triiodothyronine T3, Thyroxine T4 and Thyroid stimulating hormone (TSH), Body weight rate, and some physiological and biochemical parameters such as the total count of leukocytes (WBCs), packed cell volume (PCV) and concentrations of Hemoglobin (Hb), Glucose, Total Cholesterol(TC), Triglycerides (TG), High Density Lipoprotein (HDL - C), Low Density Lipoprotein (LDL - C), Very Low Density Lipoprotein (VLDL - C), Phospholipids, Atherogenic indices levels, Uric acid, Total protein, Albumin, Globulin, Serum Creatinine Blood urea, glutathione(GSH), Malondialdehyde(MDA), Peroxynitrite radical(ONOO - ) Ceruloplasmin(Cp), Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) in sera of male rabbits exposed to oxidative stress induced by hydrogen peroxide (0.5%) with drinking water along the period of experiment (30) days, with comparison the effect of the cabbage extract with the effect of carbimazole (anti - thyroid drug) to induce Hypothyroidism.For the purpose of this study, preliminary experiments were carried out to find the most effective dose of the cabbage extract and this dose was (300 mg/kg body weight).Rabbits (8 - 10 months age) and (950 - 1560 gm weight) were determined randomly divided into five groups, each group includes five replicates These groups are : The control group, cabbage aqueous extract group, cabbage aqueous extract and H2O2 group, carbimazole drug group and H2O2 GroupThe results showed the following : 1 - Treatment the animals with cabbage aqueous extract caused significant decrease (P<0.05) in Hb, PCV and concentrations of T3 hormone, T4 hormone, TC, LDL - C, phospholipids, second atherogenic index, blood urea, serum creatinine, albumin, MDA, (ONOO - ) radical and Cp, While it caused significant increase in weights, TSH hormone, TG, VLDL - C, glucose, globulin and GSH compared with the control group. While no significant variations were observed in total (WBCs) and concentrations of AST, ALT, HDL - C, atherogenic index (first and third), uric acid and total protein compared with the control group. 2 - Treatment of rabbits with carbimazole drug showed significant decrease in levels of body weight, Hb, PCV, and concentrations of T3 hormone, HDL - C, blood urea, albumin, glucose, GSH and Cp. This treatment showed as well a significant increase in T4 hormone, TSH hormone, ALT, TG, uric acid, VLDL - C, serum creatinine and atherogenic indices levels, Whereas showed no significant variations in total (WBCs), AST, TC, LDL - C, phospholipids, total protein, globulin, MDA and (ONOO - ) radical compared with the control group. 3 - Compared with the control group the oxidative stress induced by H2O2 caused significant decrease in concentrations of Hb, T3 hormone, HDL - C, albumin, GSH and Cp, While this stress showed a significant increase in total (WBCs), T4 hormone, ALT, TG, VLDL - C, phospho - lipids, atherogenic indices levels, serum creatinine, glucose, MDA and (ONOO - ) radical. However no significant variations were observed in weights, TSH hormone, PCV, AST, TC, LDL - C, uric acid, blood urea, total protein and globulin compared with the control group.4 - The Treatment of rabbits under oxidative stress with cabbage extract showed significant decrease in Hb, PCV, T3 hormone, TC, LDL - C, phospholipids, atherogenic indices levels, blood urea, serum creatinine, albumin, GSH, MDA, (ONOO - ) radical and Cp comparison with the control group. While a significant increase was observed in weights and concentrations of T4 hormone, TG, HDL - C, VLDL - C, uric acid, glucose and globulin, While no significant variations showed in total (WBCs), TSH hormone, ALT, AST and total protein comparison with the control group.The study results revealed that the effect of cabbage aqueous extract was better than carbimazole effect as antithyroid and as antioxidant role by reduction the harmful effects of the free radicals through some improvement was observed in many physiological and biochemical activities in the body and may be used in protection and treatment many of pathological cases specially Hyperthyroidism, cancer and cardiovascular diseases.
