    Notes: Abstract Background. The oral adsorbent, AST-120 Kureha Chemical, has been shown to attenuate the progression of chronic renal failure in rats and humans. Spontaneous hypercholesterolemic male rats, (SHC rats; SHCRs) have been introduced for experimentation because they develop progressive hyperlipidemia and glomerulosclerosis on a cholesterol-free standard diet by their 30th week of life. Methods. The effects of AST-120 were studied in SHCRs. Twenty 10-week-old SHCRs were divided into two groups: a control group (n = 10), and an AST-120 group (n = 10). The experiment was begun at the 12th week and completed at the 34th week of life. Results. At the end of the experiment, we found that the serum levels of total cholesterol were 40% lower in the AST-120 rats than in the control rats (P 〈 0.01). The creatinine clearance in the AST group was 40% higher than that in the controls (P 〈 0.05). At the age of 20 weeks, postheparin lipoprotein lipase in the AST-120 SHCRs and in Sprague-Dawley rats with normal serum lipid levels was comparable, but was clearly lower in the control SHCRs. Finally, in a pathological investigation that determined a sclerosis index for all kidneys, this was significantly lower in the AST group than in the control animals (P 〈 0.01). Conclusions. The reduction of serum lipid levels following the administration of the AST-120 oral adsorbent is associated with amelioration of renal functional and structural changes in SHCRs.

    Notes: Abstract Endothelial barrier antigen (EBA) can be used to detect the blood-brain barrier in the central nervous system of rats. This study investigated the temporal profile of antigen expression in cerebral vessels after infarction and assessed the relationship between re-establishment of this antigen in newly formed vessels and astrocytes around these vessels. Rats were subjected to cerebral ischemia for 2 h by the intraluminal thread method, then killed after 1, 3, 7, 14 and 28 days. Perfusion-fixed paraffin-embedded brains were immunostained for detection of EBA and glial fibrillary acidic protein (GFAP) by the streptavidin-biotin-peroxidase complex method. EBA immunostaining in vessels in the infarcted lesion was reduced at day 1 and had almost disappeared by day 3. Newly formed vessels were found from day 3, but were not stained at day 7. However, these new vessels were weakly stained at day 14 and definitely stained at day 28. GFAP immunostaining was completely negative around these proliferating vessels. The temporal profile of disappearance and re-expression of EBA in cerebral infarcted lesion may be associated with aggravation and improvement of brain edema, although barrier permeability was not explored in this study. The expression of this antigen has no relationship to the formation of astrocyte/endothelial contacts.
