BACKGROUND: It is of great importance in improving the clinical effect of human islet allograft to study and design models of such large animals as pigs or primates preclinically.OBJECTIVE: To evaluate the effect of different doses of streptozotocin (STZ) on inducing diabetes type Ⅰ models of nonhuman primates.DESIGN, TIME AND SETTING: A contrast observational animal experiment was performed in the Cell Transplantation and Gene Therapy Center, the Third Xiangya Hospital of Central South University from October 2007 to December 2008. MATERIALS: A total of 21 adult male rhesus monkeys were divided into a 125 mg/kg STZ group (n =5), a 75 mg/kg STZ group (n=5) and a 50 mg/kg STZ group (n=11).METHODS: STZ weighed with regard to body mass of animals was prepared into 25 g/L STZ solution with buffer that was prepared in advance. After being filtered and degermed, the new-prepared STZ of 125 mg/kg, 75 mg/kg and 50 mg/kg were administered by intravenous injection into the experimental monkeys respectively, which took 1-5 minutes.MAIN OUTCOME MEASURES: Liver and renal function, glucose metabolism and histomorphological changes of animals during 1-16 weeks following administration.RESULTS: In 125 mg/kg STZ group, two rhesus monkeys died, in 8 hours following STZ administration, of serious hypoglycemia caused by severely damaged pancreas β cells; All rhesus monkeys in this group had got significantly increased liver transaminase, serum creatinine and urea nitrogen at week 1 following STZ administration, which reached a peak during 2-4 weeks; One rhesus monkey in this group showed severe shortage of endogenous trypsin and hyperglycemia irreversible by exogenous insulin following STZ administration, and finally died at day 13 following STZ administration due to the glucose metabolic disorder, ketoacidosis, liver and renal failure; The other two survivors in this group kept high level of liver transaminase,urea nitrogen and serum creatinine throughout the observation period. In 75 mg/kg STZ group, rhesus monkeys presented significantly increased liver transaminase, serum creatinine and urea nitrogen at week 1-2 following STZ administration; After 4 weeks following administration, their liver and renal function presented with abnormality of different degrees; One rhesus monkey in this group had got injured renal function, decreased power of resistance, eyelid edema, general dropsy and irreversible infected rump after injection of STZ, and finally died at the end of week 5 following administration; Another rhesus in this group presented with irreversible continuous hyperglycemia, inappetence and significantly decreased weight, and finally died ofsystemic failure at week 9 following administration. In the 50 mg/kg STZ group, renal function of monkeys were slightly affected, with a transient mild rise which return to the normal level by the end of week 4 following administration; Only 3 animals in this group appeared eyelid edema during 1-4 weeks following administration which disappeared afterwards.CONCLUSION: STZ of 50 mg/kg is possibly the optimal dose for inducing diabetes models in most rhesus monkeys.

AIM: To explore the skills and characteristics of corneal neovascular model in rat induced by micropocket assay. ·METHODS: Nine eyes of nine Sprague-Dawley rats were studied. Pellets made of vascular endothelial growth factor (VEGF), poly-2-hydroxylethylmethacrylate and sucralfate were implanted into the corneal stroma nocloser than 1mm from the limbus. Biomicroscopic features of corneal neovascular were observed on 1,3, 5, 7th day after the implantation. ·RESULTS: On day 1 after operation, the limbal vessels were dilated, with no angiogenesis appeared. On day 3, angiogenesis began to invade peri-cornea with a brush shape, the area of CNV was (2.23±0.59) mm2. On day 5, new vessels reached the lower margin of pellet densely, the area of CNVwas (6.81±1.35)mm2. On day 7, new vessels continued to elongate, parts of them extended as loops toward the pellet, the area of CNV was (8.92± 1.79)mm2. Neither hyphema or other complications occurred.·CONCLUSION: Corneal neovascular induced by micropocket assay in rat grows steadily, with no complication, and is suitable for quantitative researches.

Background Microvessels are composed of two interacting cell types: endothelial cells and pericytes. Over the past decades, studies of corneal angiogenesis have concentrated mainly on endothelial cells, while interest in pericytes has lagged behind. Objective The present study aimed to investigate the recruitment of vascular endothelial cells and pericytes in rat corneas after alkali burn. Methods Corneal alkali burn models were established in the right eyes of 36 adult SPF SD rats by putting 4 mm medicators containing a 1% 1 mol/L NaOH solution at the central corneas for 30 seconds, and 3 matched normal rats were used as controls. Corneas were excised 1,2,3,5,7 and 10 days after surgery. Frozen sections that parallel with the corneoscleral limbus were constructed. Double immunofluorescence staining was used to observe the dynamic expression of CD31 and α-smooth muscle actin (α-SMA) in corneal tissue for the evaluation of the number of endothelial cells and pericytes. The pericyte coverage index (PCI) was calculated to quantify the recruitment of pericytes to neovascular sites. The use of experimental animals followed the Statement of Association for Research in Vision and Ophthalmology. Results CD31 was expressed in the superficial stromal layer of the cornea on the 1 st day, showing the presence of red fluoresence. The positive cell number for CD31 was gradually increased with the passage of time and proceeded into the deep stromal layer from days 2 through 5 but decreased after that. However,α-SMA was positively expressed on the 2nd day in the cornea after alkali burn with the presence of green fluorescence. The positive cell number for α-SMA was less than those of CD31 throughout the experimental period. The PCI was 0, 16.07%, 11.95%, 43.84%, 73.97% and 86. 21% , respectively, 1,2,3,5,7 and 10 days after surgery. Conclusion Pericytes recruitment to corneal new vessels may play a key role in the stabilization and maturation of angiogeneis.

Objective Toinvestigate the metabolic characteristics of triglyceride (TG) in the plasma of rabbitswith steroid?induced osteonecrosis of the femoral head and the therapeutic effect of Gushiling Capsule. Methods Rabbit model of femoral head necrosis induced by hormone was established. The level of plasma TG was detected by HPLC/MS and the relationship between the changes of plasma TG level and local histomorphology of femoral head was analyzed. Results Compared with the normal control group, significant changes of plasma TG levels were observed in the model group, the traditional Chinese medicine group and the western medicine group at each time point (P<0.01). However, no significant difference was found between the traditional Chinese medicine group and the western medicine group. Compared with the model group, only a small amount of high signal joint imaging and central signal of the femoral head were found by the MRI examination in the traditional Chinese medicine group and the western medicine group. Pathology assay results showed the degree of femoral head osteonecrosis in the Chinese medicine group was milder than that in the Western medicine group. Conclusion Gushiling Capsule and western medicine Simvastatin have the similar effect of reducing plasma TG, which may be one of the mechanisms underlying Gushiling Capsule preventing steroid?induced femoral head necrosis.

AIM: To study the effect of Ginkgo biloba extract (GbE) on the expression of connective tissue growth factor (CTGF) in the initiating stage of pulmonary fibrosis of rats after administration of bleomycin (BLM).METHODS: The expression of CTGF in lungs was detected by Western blotting. The content of hydroxyproline was assayed by the method of chloramines T. The content of malondialdehyde (MDA) in plasma was investigated by colorimetry.RESULTS: On day 14 after administration of BLM, the contents of CTGF in lungs and MDA in plasma in BLM+NS group were higher than those in NS group, respectively (P

In order to investigate the mechanism, the correlation between the odor change in Crataegi Fructus stir-fried process and 5-HMF were studied. Required samples were retrieved from Crataegi Fructus stir-fried process. Statistical quality control (SQC) was used to analyze the response values acquired by the electronic nose. At the same time, the content of 5-HMF was detected by high performance liquid chromatography (HPLC). Correlation analysis was used to analyze the relationship between the above two. Experimental results showed that SQC model established by response values of all samples could show the change law of odor in Crataegi Fructus stir-fried process and changes of 5-HMF content was dropped after the first increase. Correlation analysis showed that the odor change in Crataegi Fructus stir-fried process and 5-HMF were significantly correlated (P < 0.05). Sugar degradation reaction and the Maillard reaction may be one of the mechanisms of the odor change in Crataegi Fructus stir-fried process.
