After glaucoma filtering surgery subconjunctival injection of human recombinant tissue plasminogen activator may promote the function of glaucoma filter bleb and increase outflow facility. It can also increase postoperative complications, such as corneal damage. The aim of our research was to determine corneal endothelial permeability (Pac) in subjects with glaucoma filter bleb protected by a plasminogen activator (Actilyse, Boehringer) when haemorrhagic clots obstructing a glaucoma filtering site had occurred. Two weeks, three months and six months after goniotrephining with scleral cover, in groups with and without subconjunctival injection of 25 mg human tissue plasminogen activator, Pac was calculated. In both groups, no significant differences in the level of Pac measured by fluorophotometry were found.

The purpose of this study was to test if replacement of trans fatty acids by palmitic acid in an experimental margarine results in unfavourable effects on serum lipids and haemostatic factors. We have compared the effects of three different margarines, one based on palm oil (PALM-margarine), one based on partially hydrogenated soybean oil (TRANS- margarine) and one with a high content of polyunsaturated fatty acids (PUFA-margarine), on serum lipids in 27 young women. In nine of the participants fasting levels and diurnal postprandial levels of haemostatic variables on the 3 diets were compared. The sum of 12:0, 14:0, 16:0 provided 11% of energy (E%) in the PALM diet, the same as the sum of 12:0, 14:0, 16:0 and trans fatty acids in the TRANS-diet. Oleic acid provided 10-11E% in all three diets, while PUFA provided 5.7, 5.5 and 10.2 E%, respectively. Total fat provided 30-31% and the test margarines 26% of total energy in all three diets. Each of the diets was consumed for 17 days in a crossover design. There were no significant differences in total cholesterol, LDL-cholesterol and apoB between the TRANS- and the PALM-diet. HDL-cholesterol and apoA-I were significantly higher on the PALM-diet compared to the TRANS-diet while the ratio of LDL- to HDL-cholesterol was lower, although not significantly (P = 0.077) on the PALM-diet. Total cholesterol, LDL-cholesterol and apoB were significantly lower on the PUFA-diet compared to the two other diets. HDL-cholesterol was not different on the PALM- and the PUFA-diet while it was significantly lower on the TRANS-diet compared to the PUFA-diet. Triglycerides and Lp(a) were not different among the three diets. The diurnal postprandial state level of tissue plasminogen activator (t-PA) activity was significantly decreased on the TRANS-diet compared to the PALM-diet. t-PA activity was also decreased on the PUFA-diet compared to PALM-diet although not significantly (P=0.07). There were no significant differences in neither fasting levels or in circadian variation of t-PA antigen, PAI-1 activity, PAI-1 antigen, factor VII coagulant activity or fibrinogen between the three diets. Our results suggest that dietary palm oil may have a more favourable effect on the fibrinolytic system compared to partially hydrogenated soybean oil. We conclude that from a nutritional point of view, palmitic acid from palm oil may be a reasonable alternative to trans fatty acids from partially hydrogenated soybean oil in margarine if the aim is to avoid trans fatty acids. A palm oil based margarine is, however, less favourable than one based on a more polyunsaturated vegetable oil.

The aim of this study was to explore the mechanism of 3-methoxy puerarin on decreasing the cerebral ischemia-reperfusion injury in rats. Before the model of cerebral ischemia-reperfusion injury was made, the rats in one group (3-methoxy puerarin group, 3-MP group) were pretreated with 3-methoxy puerarin (100 mg/kg) by gavageing two times per day for seven days. At an hour before operation, the rats in the 3-MP group were additionally given 3-methoxy puerarin by gavageing once. The level of prostacyclin (PGI2) and the expression of endothelin-1 (ET-1) mRNA in cerebral tissue, the activity of plasma tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI) were measured. Cerebral tissue pathologic changes were also observed. The levels of PGI2 in cerebral tissue and the activity of plasma t-PA in 3-MP group were significantly higher than those in the group of cerebral ischemia-reperfusion injury (CIRI group) (p<0.01). The activity of plasma PAI and the expression of ET-1 mRNA in cerebral tissue in 3-MP group were significantly lower than those in CIRI group (p<0.01). The cerebral tissue pathologic changes were significant in CIRI group, which were significantly ameliorated in the 3-MP group. The study showed, in the rat model of cerebral ischemia-reperfusion injury, 3-methoxy puerarin can not only increase the level of PGI2 in cerebral tissue and the activity of plasma t-PA, but also inhibit the activity of plasma PAI and the expression of ET-1 mRNA in cerebral tissue. Those findings might be the mechanisms behind the protecting effects of 3-methoxy puerarin on the cerebral ischemia-reperfusion injury.
