[Abstract]:The effect of Lanthanum on immune function of rats with 1 lanthanum
Objective to investigate the effects of lanthanum nitrate on lymphocyte transformation rate (LTR), red cell C_ (3b) receptor rosette rate, RC_ (3b) RR) and macrophage activity (PPM). Methods 64 40 day old SD male rats were randomly divided into experimental group I, experimental group II, experimental group III and control group, 16 rats in each group. The experimental group was fed with nitrate. The dose of lanthanum acid was 0.1,2,20mg/kg weight, each 2ml, 1 times per day. The control group was fed with physiological saline, 2ml/ only, 1 times / day.10 days were killed in half (a total of 32) for short-term study. 30 days later, the remaining half of the study was done. After ten days (short-term effect) and thirty days (long-term effect), the lymphocyte turns in each group. Rate, red cell C_ (3b) receptor rosette rate and macrophage activity, and the difference between the significant test. Results short term effect: the phagocytic activity of peritoneal macrophages in the medium dose (2mg/kg) group (experimental group II) increased significantly (P < 0.05), and the lymphatic cell transformation rate, the red cell C_ (3b) receptor rosette rate increased, but not reached. To a significant level (P > 0.05). Long term effect: the rate of red blood cell C_ (3b) receptor rosette in the low dose (0.1mg/kg) group of lanthanum nitrate (experimental group I) was higher than that of the control group (P < 0.05), but the lymphocyte transformation rate and the phagocytic activity of peritoneal macrophages were all rising, but not reached the significant level (P > 0.05), and the medium dose (2mg/kg) lanthanum nitrate group (Experiment II) Lymphocyte transformation rate, erythrocyte C_ (3b) receptor rosette rate and phagocytic activity of peritoneal macrophage were significantly higher than that of control group (P < 0.05). The lymphocyte transformation rate and phagocytic activity of peritoneal macrophages in the high dose (20mg/kg body weight) group of lanthanum nitrate group (experimental group III) were lower than those of the control group, but did not reach the significant level (P > 0.05). Conclusion the rats fed with lanthanum nitrate can improve their immune ability in a certain time and a certain dose range, and the low dose of lanthanum nitrate can promote the immunity of rats, and there is a trend of inhibition in high dose.
The effect of Lanthanum on the endocrine function of rats with 2 lanthanum
Objective to investigate the effect of lanthanum nitrate on the endocrine function of rats. Methods 64 SD male rats aged 40 days old were randomly divided into experimental group I, experimental group II, experimental group III and control group, 16 rats in each group. The experimental group was fed with lanthanum nitrate solution in order of 0.1,2,20mg/kg weight, each 2ml, 1 times. The control group was fed with physiological saline, 2ml/ only, 1 times / day.10 Half of each group died (32) for short term study. 30 days later, half of the rest were executed for long-term study. After ten days (short-term impact) and thirty days (long term effect), the serum levels of thyroid hormone (T_3, T_4) and insulin (Ins) were compared and the difference was observed. Results the short-term effect: rats fed with lanthanum nitrate, The insulin level in the low dose group (0.1mg/kg), the middle dose group (2mg/kg) and the high dose group (20mg/kg) were significantly higher than the control group (P < 0.05). The changes of thyroid hormone (T_3, T_4) showed the level of T_3 secreting in the low dose group (P < 0.05) (P < 0.05). The long-term effect: rats fed with lanthanum nitrate and insulin level The changes in the low dose group (0.1mg/kg), the middle dose group (2mg/kg) and the high dose group (20mg/kg) were significantly higher than those in the control group (P < 0.05): thyroid hormone (T_3, T_4) had no significant changes (P > 0.05). Conclusion lanthanum nitrate had no significant effect on the secretion of thyroid hormone (T_3, T_4) in rats, and significantly increased the islet of rats. The secretion of a hormone.
The effect of 3 trace element fluorine on the endocrine function of mice
Objective to investigate the effect of trace element fluorine and high fluorine supplementation on the endocrine function of the thyroid and islets of mice. Methods 80 Kunming mice (19-22g) were randomly divided into 8 groups, the short-term and the long-term four groups, the four groups were the control group, experimental group I (low fluorine group), experimental group II (Gao Fuzu), experimental group III (high fluoride + Se group).10 only / The mice in the three experimental groups were injected intraperitoneally with 20mg/L fluorine sodium solution, 200mg/L fluorine sodium solution and 200mg/L fluorine sodium and 100mg/L selenite. The control mice were injected intraperitoneally with saline. Each mouse was injected once a day, each time was 1ml, the short-term experiment was 10 days, and the long-term experiment was 30 days. The comparison was compared to ten days (short-term effect) and three. After ten days (long term influence), the changes of T_3, T_4 and Ins levels in the serum of mice were compared, and the significant difference between the levels of T_3, T_4 and Ins in the low fluorine group was not significant (P > 0.05), and the level of T_4 and Ins in the high fluorine group was higher than that in the control group (P < 0.05), but the T_3 level had a rising trend, but the level of T_3 was higher than that of the control group, but the level of T_3 was higher than that in the control group. There was no significant difference (P > 0.05). The level of T_3, T_4 and Ins in the high fluoride and selenium group had a downward trend compared with the high fluorine group. The long-term effect: the level of T_3, T_4 and Ins in the low fluorine group was no significant difference compared with the control group (P > 0.05), and the level of T_4 and Ins in the high fluorine group was lower than that of the control group (P < 0.05), and the T_3 level declined, but there was no significant difference (0. > > > > > > > > > > > > 0.. 05): the level of T_3 and T_4 in the high fluoride and selenium group had a rising trend compared with the high fluorine group. The level of Ins and the high fluorine group had a downward trend. Conclusion the high fluorine state could affect the secretory function of the thyroid gland and the pancreatic islets. The thyroid gland was excited and the secretory function was enhanced in the short term, and the secretion function of the thyroid gland was weakened for a long time. Fluorine has a stimulating effect on the secretory function of islets, which can enhance its function, increase the secretion of insulin, change the function of endocrine glands such as thyroid and islet, and have a certain relationship with the intake of fluorine and the length of the intake time.
