Summary: Clinical studies revealed that angiotensin converting enzyme (ACE) inhibitor reduces proteinuria and attenuates progressive decline in renal function in IgA nephropathy. Recent studies by us and others have demonstrated that the homozygote of the D allele (DD) of the ACE insertion/deletion (I/D) polymorphism is a potential risk factor for poor prognosis in IgA nephropathy, and that this deletion polymorphism predicts the therapeutic efficacy of ACE inhibition on proteinuria and, potentially, on progressive deterioration of renal function in patients with the nephropathy. 相似文献

Bestrabucil (KM2210), the benzoate of an estradiol-chlorambucilconjugate, was used experimental cancer chemotherapy against13 human tumor xenografts serially transplanted into nude mice,and its pharmacokinetics was studied. The tumors were one esophageal,two gastric, six colon, one cholecystic and three breast carcinomas.Two tumor tissue fragments approximately 3x3x3 mm were inoculatedinto BALB/cA nude mice, which were then treated with KM2210at doses of 100, 200 and 300 mg/Kg/day orally starting 24 hrafter the transplantation or when the tumor reached a weightof 100300 mg. The concentration of KM2210 and its derivativesin the tumor xenografts, normal muscular tissue and blood wereassayed by high performance liquid chroma-tography. Six out of 13 xenografts were found to be sensitive to KM2210.The concentrations of KM2210 and its derivatives in the tumortissues of the sensitive xenografts were five to 10 times higherthan those in blood and muscular tissue, and the antitumor activitycorrelated well with the area under the curve of active metabolitesof KM2210 in the tumor. 相似文献

The reasons for morphological changes of urinary red blood cells (RBC) in patients with glomerulonephritis are still controversial. In order to evaluate the importance of mechanical damage by the glomerular basement membrane (GBM), we examined urinary RBC taken from the patients with two different diseases which have characteristic GBM changes. Urinary RBC taken from 20 patients with Alport syndrome and nine with thin GBM disease were examined using a scanning electron microscope. Nineteen out of the 20 patients (95.0%) with Alport syndrome showed ‘glomerular type’, while five of the nine patients (55.6%) with thin GBM disease showed ‘glomerular type’. These results suggest that more complicated GBM abnormalities cause more severe RBC distortion. Therefore, we conclude that mechanical damage by the GBM may be the major factor in dysmorphism of urinary RBC. 相似文献
