RESUMO

Objective To study the therapeutic effect of bitter gourd saponins on salt-sensitive kidney injury induced by high salt diet and its possible mechanism.Methods 50 Sprague Dawley (SD) rats were randomly divided into normal group,model group and low-dose,middle-dose and high-dose treatment group after 10 days of adaptive feeding.Each group had 10 rats.Except the normal group,the other four groups were given high salt diet (4.0% high salt diet) to induce salt-sensitive kidney damage in rats.The normal group and the model group were given 1.0 m/(kg · d) normal saline,and the three dosage groups of total saponins of balsam pear were given 10 mg/(kg · d),20 mg/(kg · d) and 40 mg/(kg · d) respectively.After 8 weeks of treatment,rats were sacrificed and collect the 24-hour proteinuria,creatinine.Serum creatinine,serum aldosterone,serum sodium and serum potassium were measured,and renal histopathology and the expression of podocin and nephrin were detected.Results Pathological examination of model group showed obvious glomerular sclerosis and renal interstitial fibrosis,and glomerular sclerosis in the treatment group was obviously improved by bitter gourd saponins;The systolic pressure in the model group was 170 mmHg,significantly higher than that of the normal and treatment groups,the systolic blood pressure of the treatment groups were obvious decreased when treated by bitter gourd saponins (P < 0.05);Compared with normal group,serum creatinine and 24 h proteinuria / urine creatinine in model group were significantly increased (P < 0.05),while creatinine clearance rate and aldosterone were significantly decreased (P < 0.05),and the above indexes in bitter gourd saponins treatment group were significantly improved;Compared with the model group,the protein and mRNA expression of podocin and nephrin were significantly decreased (P < 0.05),while the two indexes can be revered by bitter gourd saponins in treatment group (P < 0.05).Conclusions The bitter gourd saponins can significantly improve the symptoms of salt-induced hypertensive nephropathy in rats,which may be related with the expression of podocin and nephrin in renal tissue,thereby inhibiting glomerulosclerosis and improving renal interstitial fibrosis.

RESUMO

Objective To research Henoch-Schonlein purpura purpura (HSP) and renal pathology in children.Methods 31 hospitalized HSP children that with normal urine routine and accepted renal biopsy in our hospital.Results There were different levels of kidney pathological damage in this group of 31 cases,the results of light microscope were from grade Ⅱ to grade Ⅵ The proportion was grade Ⅱ(35.48%,11 of 31),grade Ⅲ (54.83%,17 of 31),and grade Ⅳ,Ⅴ and Ⅵ (each 1 case of 31,3.23% ).lmmunofluorescence pathology results were showed as following:merely IgA depositional (48.38%,15 of 31 ),IgA + IgG depositional ( 19.36%,6 of 31 ),IgA + IgM depositional ( 19.36%,6of 31 ),IgA + igG + IgM depositional ( 12.90%,4 of 31 ).Microalbuminuria had been founded in 14 cases,and the microalbuminuria level of 10 cases were higher than normal value( 10 of 14,71.43% ).Conclusions HSP children had renal pathologic dysfunction,even the urine routine were normal,and the detection of urine microalbumin was a significant marker in the early stage.

RESUMO

This paper is to report the pathological changes in canine renal tissues after severe steam inhalation injuries. The specimens from 84 male mongrel dogs are studied with a light microscope, and 30 tissue samples of the 84 with an electron microscope. The morphological changes of glomeruli are characterized by, hypertrophy and/or hyperplasia of the glomerular cells, the former manifested as cell enlargement, increased amount of cytoplasm and rich in organelles; retrogressive changes of the glomerular cells in varying degrees as evidenced by intra-cellular edema. The renal tubules show varying degrees of degeneration, necrosis, and casts formation. Tubular necrosis affects more frequently the proximal convoluted tubules. The etiological factors of it are briefly discussed.
