ABSTRACT
Objective To investigate the effects of L-thyroxine(LT4) on serum lipid and bone metabolism in aged patients with subclinical hypothyroidism (SH). Methods Seventy-eight patients with diagnosed SH were randomly assigned to receive LT4 (therapy group) or placebo(control group) for one year. Mean dose for LT4 replacement was (80.1?37.2) ?g/d. The changes of clinical symptoms, body mass index (BMI) and serum levels of total cholesterol(TC), triglycerides(TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol(LDL-C), apolipoprotein A 1(ApoA 1), apolipoprotein B 100 (ApoB 100 ), calcium ion(Ca 2+ ), phosphorus ion (P 3+ ) and alkaline phosphatase (AKP) and bone mineral density (BMD) were measured before and after therapy. Results After LT4 therapy, clinical symptoms were ameliorated. BMI and serum TC, TG, LDL-C and ApoB 100 levels were significantly reduced 〔(24.6?3.1 vs 23.3?2.2),(5.65?1.42 vs 4.43?0.81),(1.81?0.66 vs 1.43?0.40),(3.64?0.84 vs 2.68?0.63)mmol/L,(0.98?0.22 vs 0.83?0.21)g/L,P
ABSTRACT
AIM: To study the alteration of expression of iNOS mRNA and ecNOS mRNA in peripheral leukocytes of Wistar rats fed with fructose. METHODS: Wistar rats were randomly divided into the control group ( n =10) and the fructose feeding group( n =10). The fructose feeding group drank 12% fructose water for 6 months. The blood glucose, blood insulin, and the expression of iNOS mRNA and ecNOS mRNA in peripheral leukocytes of rats were determined. RESULTS: The levels of blood insulin ( P
