Abstract

The long-term functional and morphologic responses of the hypertrophied monkey kidney after unilateral nephrectomy to fractionated irradiation were assessed. The right kidney of 13 adult female rhesus monkeys was removed. Twelve weeks after unilateral nephrectomy (UN) the remaining kidney received fractionated doses of {gamma}-rays ranging from 35.2 Gy/16 fractions (F) up to 44 Gy/20 F. Glomerular filtration rate, effective renal plasma flow, blood urea nitrogen, serum creatinine, and hematocrit values were measured up to 107 weeks postirradiation (PI). The monkeys were killed and the remaining kidneys were removed 107 weeks PI or earlier when end-stage renal failure was exhibited. Glomeruli were scored for the presence/absence of several pathologic features including increased intercapillary eosinophilic material (ICE), ecstatic capillaries, and thrombi. The relative proportion of renal cortex occupied by glomeruli, interstitium, normal tubules or abnormal tubules was determined using a Chalkley point grid. These quantal dose response data were analyzed using a logistic regression model. Irradiation of the remaining kidney in UN monkeys resulted in a dose-dependent reduction in renal function and anemia. Glomerular dysfunction preceded tubular dysfunction. Animals receiving 44 Gy all manifested progressive clinical renal failure. Conversely, those receiving {le} 39.6 Gy showed stable, albeit impaired, renal function for themore »« less

Radiation-induced changes in the kinetics of glomerular and tubular cells in the pig kidney

Journal Article Robbins, M; Bywaters, T; Rezvani, M; ... - Radiation Research

Both kidneys of 13 mature female Large White pigs were irradiated with a single dose of 9.8 Gy {sup 60}Co {gamma} rays. The pigs were killed serially between 2 to 24 weeks after irradiation. One hour prior to sacrifice bromodeoxyuridine (BrdU) (500 mg/pig) was injected intravenously. At postmortem the kidneys were removed and tissue was taken to prepare cell suspensions. The labeling index (LI) of these suspensions was determined using flow cytometry. In vivo BrdU incorporation in tubular and glomerular cells was determined immunohistochemically. The kinetics of glomerular and tubular cells was evaluated by counting the number of labeled cells/glomerulesmore »« less

Protection from radiation nephropathy by WR-2721

Journal Article Donaldson, S; Moskowitz, P; Evans, J; ... - Radiat. Res.; (United States)

The efficacy of WR-2721 pretreatment against radiation injury to the growing kidney was evaluated in the weanling mouse. Immediately following unilateral nephrectomy, animals received intraperitoneal injections of saline or WR-2721 (220 mg/kg). Thirty minutes later both nonprotected (saline-treated) control animals and protected (WR-2721-treated) animals received 1000-rad single-fraction radiation to the remaining kidney. Other animals received WR-2721 immediately following unilateral nephrectomy but no radiation. Animals were sacrificed at 3 and 24 weeks. Nonirradiated animals treated with WR-2721 only showed normal compensatory renal growth, body growth, and renal function at 24 weeks. The nonprotected, irradiated animals exhibited renal growth inhibition without bodymore »« less

Unilateral nephrectomy 24 hours after bilateral kidney irradiation reduces damage to the function and structure of the remaining kidney

Journal Article Liao, Z; Travis, E - Radiation Research

The effect of unilateral nephrectomy 24 h after irradiation on renal function and death with renal insufficiency as well as histopathological changes in the kidney was assessed. Single doses totaling 8-18 Gy were given bilaterally to unanesthetized female and male C3Hf/Kam mice. Renal function damage was assayed by blood urea nitrogen (BUN) and hematocrit (Hct). Histological damage was quantified by two parameters: kidney area and number of surviving tubule cells along the renal capsule. The number of glomeruli was scored as an indication of the number of nephrons. Changes in the two functional parameters did not appear sooner after irradiationmore »« less

RADIATION NEPHRITIS: A CLINICOPATHOLOGIC STUDY

Journal Article Rubenstone, A; Fitch, L - American Journal of Medicine (U.S.)

Clinical and pathologic findings are correlated in five cases of radiation nephritis in an attempt to establish a new approach to the pathologic criteria for diagnosis, relating not only to clinical course but also to prognosis by use of the percutaneous renal biopsy technic. The investigation showed that in some cases certain elements of the kidney may be affected more severely than others, and that the main clinical findings depend upon which one of these elements is principally affected, i.e., glomerulus, the tubule, or interstitial tissue. The results showed that Luxton's classification of clinical and morphologic criteria of radiation nephritismore »« less

Combination radiation-adriamycin therapy: renoprival growth, functional and structural effects in the immature mouse

Conference Donaldson, S; Moskowitz, P; Canty, E; ... - Int. J. Radiat. Oncol., Biol. Phys.; (United States)

The normal tissue effects of radiation-adriamycin combination therapy were studied in the renoprival weanling mouse in an attempt to determine whether compensatory renal growth inhibition from radiation and chemotherapy could be associated with structural or functional abnormalities. Weanling BLc/sub Fl/ mice underwent unilateral nephrectomy, then single fraction renal irradiation, LD 1/21 doses of adriamycin in 5 daily doses, or combination therapy with radiation and adriamycin. Animals were sacrificed at 3, 12, and 24 weeks. Compensatory renal growth, body growth, serum blood urea nitrogen (BUN), and renal morphology by light microscopy were evaluated. Significant compensatory renal growth inhibition from radiation-adriamycin therapymore »« less
