Abstract;Renoprotective effects of Agaricus blazei fruit hot water extract(CJ-01) on the incidence and severity of renal dysfunctions in the deoxycorticosterone acetate(DOCA)-salt treated with the heminephrectomized rats were investigated. CJ-01(10g/600ml) was extracted 80.DEG.C. for 1hr and a dose of 10g/60kg/day was taken, freely. Experimental animals(32 male Wistar rats) were divided into the following five groups; I. sham-operation with 1% NaCl, II. sham-operation with CJ-01(for 90 days) diluted in 1% NaCl, III. hemi-nephrectomy with DOCA(20mg/kg s.c., one day/week for 70 days) and 1% NaCl, IV. hemi-nephrectomy with DOCA and CJ-01(for 90 days) diluted in 1% NaCl, V. hemi-nephrectomy with DOCA and CJ-01(for 49 days during the maximum hypertension was appeared) diluted in 1% NaCl. All animals were freely drinking a 1% NaCl solution through the experimental period. After the left kidney was removed, the marked increased in volume of urine was observed in the DOCA-salt treated groups(III, IV, V). Particularly, these increases were significantly enhanced compared to I and II groups after the maximum hypertension was detected. However, in the CJ-01 treated groups(IV and V), such severe hyperurination was markedly blocked whereas the severe hypertension was not inhibited. At 90 days, the weight and size of the right-side kidney in the III group was about two folds more than those of the I and II groups, although the consecutive treatment of CJ-01 seen in the IV and V groups significantly inhibited the enlargement of right side kidney. Furthermore, the abnormal values (i.e., urine protein, cholesterol, corticosterone, etc.) detected in the urine and serum examinations of the DOCA-NaCl and hemi-nephrectomized group were significantly improved by the treatment of CJ-01. The pathological evidences also elucidated the significant uroprotecive effects of CJ-01 on the severe kidney diseases.... (author abst.)
