The experiment was carried out on rats fed with synthetic diet containing torula yeasts with different levels of selenium, we collected their urine of 24 hours before the test on the 30th day and the 40th day of the test respectively. The level of acid glycosaminolycan in urine was determined by precipitate carbazole sulfate with zirconium oxychloride (ZrOCl_2) to measure glucuronate. The results by F test showed no significant difference in each group. The following two points have been reached. (a) The glucuronate level general rises in each group on the 30th day and declines on 40th day, especially in the low selenium group.(b) The more selenium the diet contains, the more glucuronate is excreted. The level of glucuronate in urine is correlated with that of blood selenium, with no significant difference.

In this paper, We present the method of using glucuronate as a parameter to determine the growth of cartilage cell in the culture media. Using this method, we observed the metabolic condition of cartilage cell and knew the effect of the serum with the various types and different concentration to the growth of cartilage cell. The. experimental method was used for the first passage chondrocyte of rabbit. We put the cartilage cell in the culture media containing different concentration of serum from calf and human; then, observed the growth of cartilage cell under the microscope, collected the medium in given time; and determined the amount of glucuronate in the medium. Our results indicated that the first passage chondrocyte of rabbit can grow in the medium containing serum of calf and human in 5%～15% Also, the study shows that it is possible to determine the amount of glucuronate in the medium as a parameter to respond the growth of the cartilage cells.

BACKGROUND: Deficit of nivalenol (NIV) and selenium (Se) is related with kashin-beck disease (KBD) to certain extent. Hyaluronic acid (HA) metabolism affects directly the polymerization of proteoglycans (PG) and normal structure and function of cartilage. The integration with HA receptor on surface of cartilage tissue is the key link in HA metabolism. Being the main receptor of HA on chondrocytic membrane, CD44 expression impacts directly HA metabolism, further affects cartilage matrix metabolism, which is extremely important to maintaining the structure and function of cartilage matrix.OBJECTIVE: To probe into the injury and protection of related etiology of KBD to target tissue cells and the mechanism on degenerative necrosis of chondrocytes.DESIGN: Randomized controlled observation was designed.SETTING: Department of Genetics and Molecular-Biology of Medical College of Xi' an Jiaotong University.MATERIALS: The experiment was performed in Key Laboratory Room on Ministry of Education associated with Environment and Disease of Xian Jiaotong University from October 2002 to July 2004. One New Zealand pedigree young rabbit aged 30 days was employed and its humerus, femurs and tibia were cut out in surgery.METHODS: With cell culture, the model of bone tissue was reconstructed in vitro, in which, NIV of various concentrations, KBD suspicious infectious agent and Se, the protective factor were added. HA receptor CD44 on chondrocytic membrane and soluble CD44 in cell culture solution were determined.MAIN OUTCOME MEASURES: ① Microscopic observation of adhesion molecule CD44 on chondrocytic surface. ② Soluble CD44 in chongrocytic culture solution.RESULTS: ① Microscopic observation of adhesion molecule CD44 on chondrocytic surface: CD expression in chondrocytic membrane was decreased with increasing of NIV concentration and it was in tendency of increasing with Se added. ② Soluble CD44 in chongrocytic culture solution:The concentration of soluble CD44 in cell culture solution was decreased gradually following the increased concentration of NIV, but it was increased in high concentration group and such tendency did not alter when Se added. Except blank control and Se control, significant difference was presented among groups (P ＜ 0.05).CONCLUSION: NIV disturbs adhesion molecule CD44 expression on chondrocytic surface and further induces metabolic disturbance of cartilage extracellular matrix. Se supplementation can resist the injury of NIV to chondrocytes, but its action is limited.

Objectives To investigate the effect of proliferation and invasiveness by turmeri cvolatile oil on human neuroblastoma cell line SH-SY5Y. Methods Cells were incubated with different concentrations of TVO in vitro. Then cell survival rate was measured by MTT assay. The effect of 160 mg/L TVO on cell migration was assessed by cell scuffing test. Invasive ability of cell was detected by Transwell test. Apoptosis of cells was detected observed by flow cytometry assay. Results Survival rate of SH-SY5Y cells decreased and apoptisis rate was abated with elevated TVO concentration and prolonged cultivation time. Level of cell migration was lower than that in control group after being cultured with 160 mg/L TVO solution for 12 , 24 and 48h. With the in-crease of TVO concentration , the invasion ability of cells gradually decreased , and the invasive force and cis-platin had no obvious difference when the concentration of drug reached 160 mg/L. Conclusion The prolifera-tion of cells can be inhibited by inhibiting the proliferation and invasiveness ability with TVO.

Objective To investigate the expressions of matrix metalloproteinases(MMPs) in Kashin-Beck disease(KBD) cartilage as well as in a KBD rat model of T-2 toxin poisoning under selenium deficient conditions, and to investigate the effect of T-2 toxin on MMP-13 expression in human chondrocytes in vitro in order to determine a possible mechanism underlying KBD. Methods Samples of articular cartilage were divided into 2 groups:controls(samples from 5 normal children, traffic accident or operation), and KBD(samples from 5 children with KBD, auctopsy). Thirty-two Sprague-Dawley rats were divided into two groups by body weight using random number table: normal diet group(n = 16) and selenium-deficient diet group(n=16). The selenium level in normal diet was 101.500μg/kg, and in selenium-deficient diet was 1.118μg/kg. Rats were fed for 4 weeks with selenium-deficient or normal diet, respectively. After successful build up of the low selenium rat model, normal diet group was then subdivided into 2 sub-groups: normal group(n = 8) and normal diet plus low T-2 toxin group(n = 8);and selenium-deficient diet group was also subdivided into 2 sub-groups: selenium-deficient group ( n = 8 ) and selenium-deficient diet plus T-2 toxin group ( n = 8 ) . T-2 toxin of 100 μg·kg-1·d-1 was administered by intragastric administration for 30 days. Then the rats were sacrificed, and their knee joints were processed for histopathological evaluation. MMP-1 and MMP-13 locations in cartilages were performed by inmmunohistochemistry. Human chondrocytes C28/I2 were cultured in vitro. The experiment was divided into 4 groups: empty vector plasmid group, MMP-13 promoter plasmid group, MMP-13 promoter plasmid plus 20 μg/L T-2 toxin group and MMP-13 promoter plasmid plus 40 μg/L T-2 toxin group. MMP-13-luciferase reporter plasmid and vector plasmid were transiently transfected into C28/I2 cells for 24 hours, and then treated with 20 - 40 μg/L T-2 toxin for 24 hours. Transactivation of human MMP-13 promoter was analyzed using luciferase reporter constructs containing sequences spanning-1602 to+20 bp in C28/I2 chondrocytes. Results The percentages of chondrocytes staining for MMP-1 in the superficial and middle zones of KBD samples [(29.73 ± 10.12)%, (28.27 ± 0.91)%] were significantly higher than those of controls[(2.47 ± 0.11)%, (0.00 ± 0.00)%, all P < 0.05]. The percentages of chondrocytes staining for MMP-13 in the superficial and middle zones of KBD samples [(13.21 ± 4.32)%, (41.85 ± 6.32)%] were significantly higher than those of controls[(5.72 ± 0.31)%, (0.00 ± 0.00)%, all P<0.05]. The percentages of chondrocytes staining for MMP-13 in the superficial and middle zones of rats fed with selenium-deficient diet plus T-2 toxin group[(13.21 ± 4.32)%, (61.85 ± 8.68)%] were significantly higher than those of the normal and selenium-deficient groups[(2.43 ± 0.22)%, (5.89 ± 0.69)%, (3.03 ± 0.29)%, (25.99 ± 0.57)%, all P < 0.05]. Moreover, T-2 toxin activated the MMP-13 promoter detected with luciferase reporter assays in C28/I2 cells. The luciferase activities in MMP-13 promoter plasmid plus 20 μg/L T-2 toxin group and MMP-13 promoter plasmid plus 40μg/L T-2 toxin group(0.082 78 ± 0.008 40, 0.103 35 ± 0.013 19) were significantly higher than those in empty vector plasmid group and MMP-13 promoter plasmid group(0.024 19 ± 0.000 96, 0.040 32 ± 0.003 56, all P < 0.05). Conclusions These data suggest that T-2 toxin induces cartilage matrix degradation through up-regulation of MMP-13 promoter expression. Increased MMPs staining intensity in KBD cartilage and the rat KBD model of T-2 toxin poisoning under selenium deficient conditions suggest that matrix degradation appear to be driven by MMPs activity.
