Objective:To investigate the effects of safflor yellow ( SY) on body fat, fatty liver and insulin resistance in diet-in-duced obese mice. Methods:Male C57BL/6 mice at the age of 4 weeks were fed with high fat diet ( HF) for 8 weeks to make the obese model. The mice were intraperitoneally injected SY (100 mg·kg-1 ·d-1 ) for 6 weeks. At the end of experiment, the introper-itoneal glucose tolerance test ( IPGTT) and insulin tolerance test ( ITT) were performed, and the body fat, blood lipid profile and the other metabolic parameters were detected. Meanwhile, the epididymis fat and liver tissue were withdrawn for HE staining, the adipo-cyte area was quantified and the morphology of liver was observed. Results:SY significantly reduced the body weight, body fat mass, adipocyte area, liver weight and blood lipid levels of the obese mice (P<0. 05), and fatty liver was obviously alleviated after the ad-ministration of SY. Meanwhile, IPITT and ITT tests showed that SY significantly improved the glucose intolerance and insulin resist-ance of the obese mice(P<0. 05). Conclusion:SY has significant weight-loss effects and it can alleviate fatty liver, and improve glu-cose intolerance and insulin resistance in diet-induced obese mice.

The X-ray radiograph, CT scan and MRI appearance of 5 patients with pathologically proven fibrous dysplasia in thoracic and lumbar spine vertebrae were retrospectively analyzed. Plain radiographs, CT scans and MR images showed the presentation of eccentric lesion with intact cortex bone and marginal sclerosis in vertebral bodies without involvement of vertebral appendix and extraosseous soft tissue. The lesion masses were round (one being oval-shaped) and radiolucent in plain radiographs and CT scans. Homogeneous long signal was observed on T1 weighted image and strongly enhanced when gadolinium was administered. On T2 weighted MRI, short signal was found in the anterior part of the mass, long signal in the posterior part, and short and slight long signal in the middle part, without partitioning and laminating change. There was a good correlation between radiological features and surgical findings. These findings may be useful to diagnose fibrous dysplasia in spine.

Objective To construct a model for persistent genital tract infection with Chlamydia trachomatis in mice with low serum iron. Methods Iron deficiency was induced in female BALB/c mice by lowiron diet. Mice with or without iron-deficency were inoculated intravaginally with direct instillation of 50 μl of bacterial suspension containing 3.4344 × 107 IFU/ml of C. trachomatis serovar E elementary body 1 week after intramuscular injection of progesterone. Moxifloxacin and ferrous sulfate, alone or in combination were given to inoculated mice with iron deficiency daily for 1 week. Subsequently, vaginal discharge was obtained from mice and observed under an immunofluorescence microscope, and tissue specimens were resected from the uterus,uterine tube and ovary of mice and subjected to pathological examination at various time points. Results Compared with normal-iron mice, iron-deficient mice were infected with C. trachomatis for a longer duration (more than 18 weeks). After 18-week infection with C. trachomatis, there was an obvious chronic inflammation and lymphocytic infiltration in tissues specimens from the uterus,uterine tube and ovary of mice. Immunofluorescent examination of vaginal discharge for C. trachomatis turned negative in 60% of iron-deficient mice treated with both moxifloxacin and ferrous sulfate, but not in any of those receiving moxifloxacin or ferrous sulfate alone. Conclusion As animal models show, low serum iron may contribute to the persistent genital tract infection with C. trachomatis.
