Abstract
Twenty male Wistar rats, weighing 150 g, were placed in metabolic cages on a 30% sucrose diet for 7 days, before allocation to two groups: a control group (n = 5) and a lactose group (n = 15). They received respectively a 30% sucrose diet or a 30% lactose diet for 8 weeks, each containing 0.67% calcium and 0.38% phosphorus. After 4 (T1) and 8 (T2) weeks, the serum calcium (Ca) and citrate levels were significantly (P < 0.01) higher in rats fed the lactose diet. Serum alkaline phosphatase activity was increased in the lactose group (P < 0.01) at T1 and T2. The lactose-rich diet induced an increase in urinary Ca excretion at T1 and T2; citrate excretion was only enhanced at T2 (P < 0.001). No difference between the two groups was observed in urinary oxalate (Ox) excretion or creatinine clearance. Crystalluria analysis revealed a marked number (>300/mm3 at T1 and T2) of calcium oxalate dihydrate crystals (COD) in rats fed the lactose-rich diet, whereas no COD crystals were observed in sucrose-fed control rats at any time point. The formation of COD crystals in lactose-fed rats was related to an increase in calcium oxalate (CaOx) product (pCaOx), which was respectively 12.6 vs 3.9 at T1 and 10.5 vs 1.8 at T2, and an increase in CaOx ratio (Ca/Ox), which was 99.1 vs 7.5 and 67.5 vs 18.5 at T1 and T2, respectively. The high pCaOx and Ca/Ox ratios in the lactose group were due to hypercalciuria, in agreement with the number and the type of crystals. The present experimental model confirms that the ingestion of a 30% lactose diet increases urinary Ca excretion without changing urinary Ox excretion and shows for the first time that it induces a stable and marked crystalluria composed of COD. Such a non-nephrotoxic and stable model is of interest for the study of CaOx crystal formation secondary to hypercalciuria, and thus afterwards eventually for CaOx nephrolithiasis.

Abstract
Numerous studies of calcium oxalate crystal formation have been carried out in the past two decades. In the present study, experiments were carried out to validate a turbidimetric method allowing to assess the calcium oxalate crystallization process. This method is quick and reproducible and can be used to quantify the inhibition of calcium oxalate crystal growth by various compounds. An experimental method of validation has been developed, which consisted in filtering solutions pure or containing modifiers at given crystallization times, photographing the filters used on scanning electron microscopy and analyzing the images using mathematical methodology. The results obtained through image analysis, namely crystal density (mean particle number per unit volume) and mean area, were correlated with the turbidimetric parameters. This finding was consistent with the qualitative examination of the photographs. Moreover, the morphological differences in crystals observed on the photographs were confirmed by the calculated length/width ratio. One can therefore assume that inhibition of calcium oxalate crystal growth is at least, partly explained by surface adsorption phenomena, which may add to complex formation.

Abstract
Ligated ileal loops, 30 cm in length, of 4-month-old male Wistar rats were instilled with 3 ml of a 10 mM CaCl2 solution (added with 0.25 muCi 45Ca) in the absence (control) or presence of 100mM sorbitol, L-xylose, or creatine. Ileal calcium (Ca) transport, measured by plasma 45Ca appearance, was found to be similar 30 minutes after fluid instillation in all four instances. However, thereafter, 45Ca appearance in plasma did not increase further in control animals whereas it increased twice as much during the subsequent 30 minutes in the presence of sorbitol, L-xylose, or creatine. However, when loops of similar length were instilled with only 1.0 ml of such solutions, the sorbitol effect was already observed during the first 30 minutes. The stimulation of ileal Ca absorption induced by the presence of sorbitol appeared to be due to a cellular effect, associated with a decreased flux across the paracellular pathway, as indicated by 3H-mannitol absorption. The presence of sorbitol in instilled ileal solution induced a significant decrease in luminal Na, K, bicarbonate, and Cl concentrations at each time point studied (30, 60, 120, or 240 minutes after instillation). Thirty minutes after instillation, no difference in soluble Ca concentration was observed between control and experimental rats. After 60 minutes, Ca concentration was dramatically decreased in control rats but it remained nearly constant in experimental animals. Thus, the presence of substances enhancing ileal Ca transport favored the maintenance of soluble Ca in ileal solution during longer time periods than their absence. In the ileal enterocyte, these substances induced a twofold increase of ATP content compared with controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The administration of recombinant human erythropoietin (rHuEpo) to anemic chronic renal failure patients may be associated with an increase in blood pressure, possibly by direct effects on peripheral blood vessels. The experiments of the present study were designed to explore the hypothesis that rHuEpo might exert mitogenic effects on vascular smooth muscle cells (VSMCs), and that pre-existing hypertension might be a predisposing condition. Cultured aortic VSMCs from spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rats were studied for DNA synthesis, phospholipase C activity, and cell growth related proto-oncogene expression in the presence of rHuEpo. In cells from both rat strains, rHuEpo dose-dependently increased DNA synthesis and stimulated phospholipase C activity, as indicated by 3H-thymidine incorporation and inositol phosphate formation, respectively. Exposure of VSMCs to rHuEpo for various periods gradually increased the levels of c-myc and JunB mRNAs and transiently induced c-fos mRNA expression as determined by Northern analysis. The hormone-induced DNA synthesis was markedly enhanced in VSMCs from SHR compared to those from WKY. In contrast, rHuEpo-induced phospholipase C activity and proto-oncogene expression did not differ between the two strains. Taken together, these results suggest that rHuEpo may function as a vascular smooth muscle cell growth promoting factor through activation of the phospholipase C cascade and a modulation of proto-oncogene expression. It could thereby contribute to vascular hypertrophy and arterial hypertension.

Abstract
OBJECTIVES AND METHODS The effect of the presence of phosphates or citrate on ileal calcium (Ca) absorption was studied by using rat ileum mounted in a Ussing chamber. RESULTS Mucosa-to-serosa and serosa-to-mucosa undirectional fluxes were not modified by mucosal addition of 2.8 mM Na phosphate or 2.0 mM Na citrate to Krebs-Ringer-bicarbonate buffer containing 1.25 mM CaCl2. However, 50 mM Na citrate induced a significant and similar increase of both unidirectional Ca fluxes, leading to no modification of net Ca flux. This high citrate concentration was associated with a significant increase of tissue conductance and no alteration of zona adherens and tight junction as observed by electron microscopy. CONCLUSIONS Thus in the absence of any Ca gradient along the epithelium, even at high concentration, citrate did not induced modification of ileal Ca absorption.

Abstract
The nucleation and crystal growth of calcium oxalate (CaOx) were studied at pH 5.5 using turbidimetric measurements at 620 nm of suspensions produced by mixing calcium chloride and sodium oxalate (initial conditions: Ca, 3 x 10(-3) M; Ox, 0.5 x 10(-3) M). CaOx crystallization kinetics were defined first by the induction time ti and then by the slope of turbidity as a function of time during the interval corresponding to a correlation coefficient r2 > 0.99. The technique described requires only a small amount of material, is quick, convenient, and can be used to study inhibitors of CaOx crystallization by comparing ti and the rate of crystal growth in the presence and absence of inhibitors. The effects on CaOx crystal growth of several low molecular weight compounds, i.e. di- and tricarboxylic acids, were examined. The majority of these compounds were inhibitors of crystal growth, the greatest effect being seen with citric acid (50% inhibition in the presence of 1.5 x 10(-3) M citric acid), isocitric acid (50% inhibition in the presence of 0.75 x 10(-3) M isocitric acid) and pyrophosphate (30% inhibition in presence of 0.15 x 10(-3) M pyrophosphate). The inhibitors' behaviour regarding the medium was studied without any assumptions about their possible mechanisms of action. Measurements of ionized calcium before and after the reaction, as well as the observation of crystals by scanning electron microscopy, allowed us to formulate the hypothesis that the effect of citric acid and tartaric acid can be attributed mainly to ion pairing, in contrast to that of pyrophosphate and the other carboxylic acids.

Abstract
By the year 2000, the perspectives for hemodialysis performed in adults will be oriented towards facilitation of the practice of hemodialysis as a better control of clinical symptoms observed in end stage renal failure treated by hemodialysis. Blood access is the main problem which remains to be solved. The authors describe the advantages and disadvantages of the methods presently used and give the "state of the art" of "blood access" prosthesis. Almost all symptoms encountered in renal failure patients treated by hemodialysis can be efficiently treated. Hypotensive drugs usually reduce hypertension which resists adequate treatment by hemodialysis. Most of the symptoms of osteodystrophy can be avoided by adequate diet associated with the prescription of vitamin D analogs. Nevertheless, the prolongation of hemodialysis treatment duration over 7 years has led to the apparition of destructive arthropathies which are very painful and handicapping. They are related to amyloid deposit of beta 2-microglobulins. Progress in hemodialysis technics and a better control of uremic symptoms allow application of this treatment at all ages of life. The authors examine specific problems concerning school-aged teenagers and aged persons. They show that results already achieved allow a daily treatment of these patients. This is a first step for the generalisation of this procedure to all patients and its advantages are described. Improvement of hemodialysis technics for the year 2000, as can be expected, mainly depends upon progress in knowledge of biocompatibility parameters between materials used in the artificial kidney and patients tissues, mainly blood vessels.

Abstract
A systematic study of the upper cervical spine was performed using magnetic resonance imaging in 25 patients (15 men and 10 women) who had been undergoing hemodialysis for more than 10 years. Seven pseudotumors of the periodontoid soft tissue were disclosed, which were similar to the pannus recently described in rheumatoid arthritis. Bone cystic radiolucencies were observed in association with these pseudotumors in 5 patients. The radiolucencies were located in the atlas (1 in the lateral mass and 1 in the anterior branch) and in the axis (3 in the odontoid process and 1 in the vertebral body). No horizontal or vertical atlantoaxial subluxation was demonstrated. These features were observed only in patients who had amyloid arthropathy. They could be a frequent, yet thus far little-recognized, feature of beta 2-microglobulin amyloidosis.

Abstract
The production and targeting of a major T cell derived lymphokine, Interleukin 2 (IL-2), were studied in 23 uremic patients undergoing regular hemodialysis treatment and 20 uremic patients prior to the onset of renal replacement therapy. In hemodialyzed patients, abnormally increased proportions of circulating T cells spontaneously expressing high affinity IL-2 receptors (IL-2 Rec) were detected: they bound a monoclonal antibody specifically directed to the IL-2 Rec 55 kDa chain (Tac antigen) (mean +/- SEM: 7.12 +/- 0.81% in patients vs. 2.15 +/- 0.39% in normal controls, P less than 0.0001) and significantly proliferated in presence of human recombinant IL-2 alone (mean +/- SEM: 5438 +/- 729 cpm in patients vs. 1647 +/- 244 cpm in normal controls). Hemodialyzed patients also exhibited significantly increased serum levels of soluble IL-2 receptor (mean +/- SEM: 4036 +/- 947 U/ml in patients vs. 253 +/- 29 U/ml in normal controls. P less than 0.001). Moreover, a significantly decreased IL-2 activity was detected in the supernatants of stimulated T cells from hemodialyzed patients (mean +/- SEM: 0.93 +/- 0.12 U/ml in patients vs. 2.49 +/- 0.22 U/ml in normal controls, P less than 0.0001). In nine hemodialyzed patients who were analyzed before and immediately after the hemodialysis session no acute modifications of the various parameters analyzed were detected. Although less profound, a similar pattern of T cell abnormalities was observed in the uremic non-hemodialyzed patients studied.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In eleven patients with uraemia on intermittent haemodialysis treatment, recombinant human erythropoietin (rHuEpo) was used at a dosage schedule of 100 IU/kg bodyweight thrice weekly. Erythrokinetic studies (blood volume, RBC survival and iron kinetics) were performed in nine cases before and after 6 months of treatment. The remaining two patients had only RBC and plasma volume determinations before and after treatment. Although total blood volume remained unchanged, RBC volume was increased in all cases. Red cell loss was not modified, and quantitative improvement of RBC production was noted in all cases. No qualitative defect of erythroid maturation or release was observed in the treated patients. In conclusion, rHuEpo treatment improves the anaemia of haemodialysis patients by normalising circulating RBC volume only through an increase in red cell production.

Abstract
The beta-2 microglobulin type of amyloidosis was identified in articular and para-articular tissues of 14 patients with non-amyloid nephropathies undergoing long-term hemodialysis. Ten patients had carpal tunnel syndrome, 13 had juxta-articular radiolucent cysts (complicated by spontaneous fractures of the femoral neck in three), and six had destructive arthropathies of the large joints of the limbs. Massive amyloid deposits were found in the synovium, capsule, ligaments, articular cartilage, and/or bone. They were characterized by Congo red-induced green birefringence that was sensitive to potassium permanganate treatment. They reacted with anti-beta-2 microglobulin antiserum, whereas they did not react with antibodies directed against AA protein, prealbumin, or immunoglobulins. These data suggest that the potentially disabling arthropathy of hemodialysis is due to amyloid lesions. The persistently elevated plasma beta-2 microglobulin levels may play a role in the pathogenesis of this recently recognized complication, and if so, this complication should be preventable.

Abstract
Interleukin 2 (IL-2) and B-cell growth factors I and II (BCGF I and BCGF II) are lymphokines produced by T cells that play a major role in T- and B-cell cooperation. Peripheral blood lymphocytes from 12 uremic patients undergoing intermittent hemodialysis were tested for their capacity to produce IL-2 and BCGFs and to respond to these soluble mediators. IL-2 and BCGF activities were determined by means of two biological assays (proliferation of IL-2-dependent cytotoxic T-cell line CTLL-2 and of anti-human IgM (mu chain)-stimulated normal B cells, respectively) in the supernatants of phytohemagglutinin A-stimulated T-cell cultures. IL-2 activity was significantly decreased in patients as compared to normal controls (mean +/- SEM, 0.28 +/- 0.09 unit per ml) in hemodialyzed patients versus 1.02 +/- 0.16 units per ml in normal controls). This profound abnormality contrasted with the normal activity of the BCGFs that was invariably observed in the same supernatants. A similar dissociation was detected when analyzing the sensitivity of uremic B and T cells to exogenous purified lymphokines. Anti-IgM (mu chain)-stimulated uremic B cells exhibited a normal response to recombinant IL-2 and to chromatography-purified BCGF I and BCGF II. Resting B cells did not show any increased reactivity to these lymphokines. In contrast, whereas in normal controls recombinant IL-2 exclusively induced the proliferation of T cells that had been previously activated by a mitogen, resting T cells from uremic patients were highly responsive to exogenous IL-2. This abnormal response was paralleled by significantly increased proportions of peripheral T cells recognized by the anti-Tac monoclonal antibody that specifically binds to the IL-2 receptor. These data clearly show the existence in hemodialyzed patients of abnormally high proportions of T cells presenting phenotypic and functional signs of preactivation. This increased T-cell IL-2 receptor expression may offer an explanation to the deficient IL-2 activity observed in patients' supernatants (by inducing increased absorption of the lymphokine). The potential relevance of these preactivated T cells to the depressed cell-mediated immunity observed in hemodialyzed patients is outlined.

Abstract
To define the role of insulin in lipid disturbances of chronic renal failure, chronically uremic rats (U+) were supplemented by continuous insulin infusion over a 35-day experimental period and compared with control ad libitum-fed rats (C) and uremic rats without insulin (U). Uremic rats were characterized by hypoinsulinemia, an increase in both circulating very low-density lipoprotein (VLDL) and their cholesterol concentration, a normal hepatic triglyceride secretion rate (TGSR) determined with Triton WR 1339, and a low adipose tissue lipoprotein lipase (LPL) activity. Chronic insulin infusion at low rate (0.5 IU/24 h) to U+ rats normalized serum insulin (from 17.0 +/- 0.6 mU/l in U rats to 23.4 +/- 1.7 mU/l in U+ rats), serum VLDL triglycerides (from 804 +/- 65 to 410 +/- 36 mg/l), and serum VLDL cholesterol (from 43 +/- 8 to 16 +/- 3 mg/l). Hepatic TGSR decreased significantly after insulin treatment (from 0.58 +/- 0.03 to 0.44 +/- 0.03 mumol/min). Moreover, adipose tissue LPL was restored to normal by insulin supplementation (from 460 +/- 60 to 860 +/- 150 mU per total epididymal fat in U and U+ rats, respectively). Correction of the disturbed VLDL metabolism was associated with multiple actions of insulin including 1) a decrease of peripheral lipolysis, 2) a decrease of hepatic TGSR, and 3) an increase of adipose tissue LPL activity. Because cholesterol-rich VLDL are potentially atherogenic, their normalization with insulin treatment in this animal model suggests a viable area of investigation for the prevention of accelerated atherogenesis in chronic renal failure.

Abstract
The possible mechanisms of the increase in serum triglycerides (TG) and TG-rich lipoproteins were studied in chronically uremic (U) rats by comparison with either ad-lib fed control (C) rats or diet-restricted (DR), sham-operated pair-fed control rats. A first series of animals was studied in the fed state and a second series after a 16-hr fast. In U animals the concentration of serum TG and TG-rich particles was lower than that of C rats in the fed state but significantly higher than that of C and DR rats after a 16-hr fast. Serum glucose and lactate concentrations in the fed or fasted state were unchanged by uremia. Serum insulin concentration was significantly decreased in U rats as compared to C and DR rats in both series. The fast did not increase the concentration of serum nonesterified fatty acids (NEFA) in U or DR animals to the same extent as in C rats, whereas the serum concentration of beta-hydroxybutyrate (BOB), which was higher than that of C rats in the fed state, was significantly lower after a 16-hr fast. In U animals, as compared to control rats of either series, a significant decrease of epididymal lipoprotein lipase (LPL) activity was observed during both nutritional states when expressing the enzymic activity per number of cells. In conclusion, our data provide evidence against hepatic over-production of TG-rich lipoproteins in rats with chronic renal failure and strongly point to an LPL-mediated defect of their peripheral catabolism, probably related to the insulin deficiency state.

Abstract
Spinal radiologic lesions suggestive of destructive spondylarthropathy were found in 10 patients on long-term hemodialysis. These lesions were characterized by severe narrowing of the intervertebral disc, associated with erosions and geodes of the adjacent vertebral plates without osteophytosis. In 9 of the 10 patients the lesions were located in the cervical spine, and in 1 patient, in the lumbar spine. Microbial spondylitis, degenerative disc disease, and destructive spondylarthropathy of calcium pyrophosphate dihydrate deposition disease were each, in turn, ruled out. The finding of apatite crystals by transmission electron microscopy in 1 disc specimen suggests that these crystals may be associated with destructive vertebral disc lesions in dialysis patients.

Abstract
Ten patients with a uremic polyneuropathy were investigated. Chronic renal failure was associated with a variety of neuropathies, including an acute axonal neuropathy, a progressive axonal neuropathy with secondary segmental demyelination, and a predominantly demyelinative neuropathy. All patterns were associated with distal degeneration of fibers evidenced by axonal sprouting observed on single-fiber preparations. The etiology of such variations in pathology of uremic neuropathy is still not clearly understood.

Abstract
Three cases are reported in which unexpected generalized amyloïdosis was disclosed by biopsies. The authors emphasize the value of precise analysis of the deposits and particularly of Wright's method for studying their staining properties. This method can guide investigations towards one of the two main etiologies of amyloïdosis (immunoglobulinic or AA).

Abstract
Cardiovascular accidents are the commonest cause of death in patients on intermittent haemodialysis. Our study concerns 158 adult patients in terminal renal failure who were treated by periodic dialysis; it was carried out at Necker Hospital between January 1967 and December 1970. Between these dates, 35 patients died, 17 of the deaths being due to unequivocal or probable cardiovascular complications. The diagnosis of cerebrovascular accident was made in 13 cases. The mean age of the patients who died was 38 years. Fatal cerebrovascular accidents occurred especially during the first 12 to 24 months of treatment. The incidence of fatal vascular accidents is greatest in patients who were hypertensive at the beginning of periodic dialysis, and who remained so after six months of dialysis. Our study has therefore shown that hypertension in patients on chronic haemodialysis is a major vascular risk factors; other risk factors, especially metabolic ones, may also play a part.

Abstract
The tolerance to high levels of ultrafiltration that has been observed when using a RP-6 dialyzer with polyacrylonitrile membrane and a closed batch dialysate delivery system has led the authors to put patients on a free sodium and fluid intake. Eight patients were put on such a diet for six months. They have been dialyzed four to five hours, three times per week, on a RP-6-Rhodial 75. The mean intersession weight gain was 4.29+/-0.18 Kg after three days for a mean predialytic body weight of 63.55+/-2.54 Kg. Mean predialytic blood pressure was 1.38+/-4 mmHg for systolic pressure and 82+/-5 mmHg for diastolic pressure. Mean ultrafiltrate volume was 4.86+/-0.36 liters which corresponds to a sodium output of 661.3+/-49.5 mEq. Total plasma protein and hematocrit increased 18.8+/-3.34% and 19.13+/-3.22%, respectively, when the pre and post-dialytic values were compared. No clinical sign of fluid overload (dyspnea, edema, etc.) was noted in these patients. Cardiothoracic index remained in the normal range. This tolerance is due, possibly, to the high sodium concentration (145 mEq/L) in the dialysate. The free sodium and water diet may contribute to a better rehabilitation.

Abstract
Platelet functions and blood coagulation have been regularly investigated in 31 patients undergoing maintenance haemodialysis for 5 months to 6 years. Fifteen of them suffered from at least two arteriovenous fistula thrombosis during the year prior the first examination. Eleven patients, including eight with recurrent thrombosis, received 300-400 mg per day dipyridamole during 1 month to 2 years. Some abnormalities are commonly observed in the whole studied population: lowering of platelet adhesiveness, defective aggregation in the presence of both collagen and ADP 5. 10-5 M; increased level of factor V and mainly factor VIII. Mean platelet factor 3 activity was in the normal range with variations from one case to another. The only unusual feature observed in patients with recurrent thrombosis was an increase of platelet aggregation induced by ADP 0.5. 10-6 M. Neither spontaneous aggregation nor significant abnormality of plasminogen level and plasma antithrombin activity were observed. Under dipyridamole therapy, correction of platelet hyperaggregability was observed in all patients and improvement of platelet adhesiveness in half the studied cases (despite the unchanged anaemia). The treatment significantly decreased the frequency of arteriovnous fistule thrombosis in the six patients observed during two consecutive years, the first one without and the second under treatment: the total number of thrombosis was 18 during the first and 3 in the second period.
