AIM：To investigate the antiangiogenic effects and safety of topically administered low-molecular-weight heparintaurocholate 7（LHT7） on corneal neovascularization（CoNV）.METHODS：Twenty-four Sprague-Dawley rats were randomly distributed into four groups of six rats *** central corneas were cauterized using a silver/potassium nitrate *** 2d after cauterization,12.5 mg/mL（low LHT7 group） or 25 mg/mL（high LHT7group） LHT7 was topically administered three times daily;12.5 mg/mL bevacizumab was topically administered as positive control（bevacizumab） group,with normal saline（NS） administered as negative control（NS group）.The corneas were digitally photographed to calculate the CoNV percentage from the neovascularized corneal area at 1 and ***：The 4 study groups did not have different CoNV percentages at 1wk after injury（P〉0.05）.However,the low LHT,high LHT,and bevacizumab groups had significantly lower CoNV percentages than the NS group at 2wk（all P〈0.05）.No significant differences in CoNV percentage were found among the low LHT,high LHT,and bevacizumab groups（all P〉0.05）.All groups except the NS group had lower CoNV percentages at 2wk postinjury than the levels observed at 1wk（all P〈0.05）.CONCLUSION：Topically-administered LHT7 inhibited CoNV without complication after chemical cauterization in the rat.

Objective To evaluate the effect of 3-month kale （Brassica oleracea acephala） juice supplementation on coronary artery disease risk factors among hypercholesterolemic men. Methods Thirty-two men with hypercholesterolemia （〉 200 mg/dL） were recruited after annual health examinations among the faculty and staff at university. The subjects consumed 150 mL of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed and blood samples were collected to evaluate biochemical profiles before and after supplementation. Results Serum concentrations of HDL-cholesterol, and HDL- to LDL-cholesterol ratio were significantly increased by 27% （P〈0.0001） and 52% （P〈0.0001）, respectively. The LDL-cholesterol concentration and the atherogenic index were significantly reduced by 10% （P=0.0007） and 24.2% （P〈0.0001）, respectively without affecting body mass index, waist and hip circumferences, or nutrient intakes after three months of supplementation. While there was no difference in the concentration of malondialdehyde, significant increase in glutathione peroxidase activity （P=0.0005） were accompanied by a significant increase in the serum selenium level （P=0.0132）. It was also found that the responses of these risk factors to kale juice administration were dependent on smoking status. Conclusion Regular meals supplementation with kale juice can favorably influence serum lipid profiles and antioxidant systems, and hence contribute to reduce the risks of coronary artery disease in male subjects with hyperlipidemia.
