Background. Although Aristolochia manshuriensis (AM), which was incriminated in the Japanese variety of Chinese herbs nephropathy, has been recently shown to be nephrotoxic in rats, less is known about whether this toxicity is attributable to its aristolochic acids (AA). We compared the renal effect of AM with that of Akebia quinata (AQ), which has similar components to AM but is free of AA
we also compared this effect of AM with that of pure AA, and studied its possible mechanism. Methods. In study 1, rats were divided into four groups. Each group was orally given either 0.4 g of AM, 4 g of AM, or 4 g of AQ per day, or vehicle, for 5 days. In study 2, rats were given 4 g of AM (which contained 4 mg of AA), or 4 mg of pure AA per day, or vehicle, for 5 days. Renal function, and renal histology were evaluated on day 5 in study 1 and on days 1, 3, 5, and 14 in study 2. In study 2, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL) and proliferating cell nuclear antigen (PCNA) staining were also performed. In study 3, rats were treated in the same way as in study 2, but were all killed on day 5. Concentrations of AA (I + II) were measured in serum and urine in study 2, and in the kidney, lung, heart, liver, and spleen in study 3. Results. In study 1, only the rats that received 4 g/day of AM developed tubular necrosis, azotemia, proteinuria, and glucosuria. In study 2, both AM- and AA-treated rats showed progressive tubular damage, decreased renal function, and increased urinary protein excretion. The degree of these alterations was comparable in the AM and AA groups. Moreover, the concentrations of AA (I + II), in serum, urine, and kidney were also comparable in the AM- and AA-treated rats. High levels of AA were detected in the lung and kidney. Apoptotic tubular cells increased on day 5 and had decreased by day 14 after the withdrawal of AM or AA. Meanwhile, proliferating tubular cells progressively increased from day 3 to day 14. Conclusions. Our study indicates that the renal toxicity of AM can be attributed to its AA component. Tubular cell apoptosis might be one of the mechanisms involved in this renal injury.

CD59, the sole membrane regulator of the membrane attack complex of complement, is broadly and abundantly expressed in man and other mammals. In mouse, CD59 is encoded by two homologous genes. The expression patterns and functional roles of the proteins encoded by these genes, mCD59a and mCD59b, have not been well characterized. Here we describe the generation of monoclonal and polyclonal antibodies detecting specifically mCD59a and mCD59b. These reagents have been used to study function and to ascertain the cell and tissue distributions of mCD59a and mCD59b. mCD59a was broadly distributed on endothelia, erythrocytes, platelets, and on numerous other cell types in organs, a distribution pattern resembling that of CD59 in other species. In marked contrast, expression of mCD59b was restricted to germ cell elements in the testis and mature spermatozoa. Both mCD59a and CD59b inhibited human and rodent complement with similar efficiency. These findings demonstrate that the broadly distributed mCD59a is the key regulator of the terminal complement pathway in mice whereas CD59b, expressed only in testis and on sperm, probably plays other roles in vivo.
