    Notes: Abstract Analysis of single-stranded conformation polymorphisms in polymerase chain reaction (PCR) products (PCR-SSCP) is a sensitive method for detecting point mutations in genomic DNA. To investigate its utility in examining the androgen receptor gene, we analyzed data on a patient with the testicular feminization syndrome (TFS) with a known point mutation in exon C. We detected mobility shifts of fragments of the corresponding region. Since examination of the subject's brother (legally sister), who also has TFS, revealed an identical shift pattern, we sequenced the exon C of the sibling and detected a mutation identical to that in the former. We conclude that PCR-SSCP is available for screening mutations of the androgen receptor gene.

    Notes: Abstract Histopathological findings in renal allograft with stable function remain unclear. We therefore performed non-episode biopsy in the long-surviving renal allograft to investigate the histopathological changes. Our data show that, although arteriolopathy is characteristic of drug-induced nephropathy, it is unrelated to dosage and concentration of cyclosporine or tacrolimus in non-episode biopsy. We evaluated therefore the clinicopathological findings of arteriolopathy in this study. Non-episode biopsy was defined as follows: as serum creatinine level lower than, 2.0 mg/dl and a urinary protein level lower than 500 mg/day. A total of 65 biopsy specimens were enrolled in this study as non-episode biopsy. Twenty-nine specimens revealed arteriolopathy. There were no statistically significant differences between arteriolopathy and dosage or concentration of cyclosporine or tacrolimus. Arteriolopathy in non-episode biopsy was related to time of biopsy, kidney age, hypertension, and hyperlipidemia, suggesting that it is important for graft survival to strictly control blood pressure and blood lipid level.

    Notes: Abstract Nine renal transplant recipients in stable systemic condition on FK506 capsules were converted to FK506 granules in order to investigate the safety, efficacy, and pharmacokinetics of the granular formulation of FK506. The study period for the administration of FK506 granules was 4 weeks, and in principle, the oral dose was the same as that of the FK506 capsules. Renal graft function remained stable and no rejection signs were noticed while the patients were taking the granules. The area under the blood concentration-time curve (AUC), the maximum blood level (Cmax), and the time to reach Cmax (Tmax) after FK506 capsules and FK506 granules were, respectively, 93.1 ± 66.4 and 97.0 ± 89.1 ng · h/ml (P = 0.81), 12.7 ± 7.1 and 15.2 ± 11.7 ng/ml (P = 0.39), and 2.0 ± 1.7 and 1.3 ± 0.6 h (P = 0.29). The mean trough blood level during FK506 medication was 4.25 ± 3.42 and 4.02 ± 3.83 ng/ml, respectively, for the capsules and the granules. FK506 granules, a new formulation, showed an efficacy comparable to that of the FK506 capsular formulation.
