In 11 uremic patients serum zinc, copper and magnesium were determined prior to and 3—6 months after starting intermittent peritoneal dialysis (IPD). The trace elements were measured by atomic absorption spectrophotometry. The concentrations of serum zinc and copper were raised significantly from the initial mean values of 9.36±2.498 μmol/L and 15.875±4.223 μmol/L prior to IPD to 12.102±2.514 μmol/L and 22.127 ±3.530 μmol/L respectively after IPD. While in normal controls serum zinc was 13.571±1.665 μmol/L and copper 15.830±4.113 μmol/L. Serum magnesium dropped from 2.127±0. 712 mmol/L to 1.921±0.378 mmol/L、but the change was not significant statistically; the value in normal controls was 1.300±0.128 mmol/L. When IPD had been well established and there was no sign of peritonitis, serum zinc, copper and magnesium were tested before and after the procedure of IPD in a single day at random, and at the same time the concentrations of these elements in the drained dialysate were also determined. The result showed that serum levels of zine, copper and magnesium remained unchanged before and after dialysis in a single day, however, those in the drained dialysate were raised from the initial values of 1.301±0.522 μmol/L, 0.9635±0.335 μmol/L and 1.168±0.411 mmol/L to 8.478±5.324 μmol/L, 5.715±1.868 μmol/L and 1.098±0.494 mmol/L. 相似文献

16例尿毒症血透患者分成三组。第一组6例常规维持血透,自由进食;第二组5例低蛋白饮食,蛋白量为0.6g·kg~(-1)/a,第三组5例极低蛋白饮食,蛋白量为0.3~0.4g·kg~(-1)/d,供给必需氨基酸或酮酸。二、三组每周血透1次,所有患者均观察6个月。结果示三组患者营养状态相似,氮平衡、总体氮流量、蛋白合成速度均有改善,二和三组患者血磷明显降低,血钙明显升高,其Ccr下降率明显慢于一组,提示血透联合低蛋白饮食或(和)加必需氨基酸可以减少血透次数,能保护残存肾单位功能。 相似文献

EFFECT OF LOW PROTEIN DIE'T ON WHOLE BODY
NITROGEN METABOLISM IN PATIENTS WITH CHRONIC
RENAL FAILURE

isN-glycine was administered orally as a tracer
t0 3 patients with chronic renal failure (CRF) in the
study of total body protein metabolism during the
course of diet therapy. Five healthy subjects with
matched age and sex served as controls. Patients on
a diet providing l.2 g protein/kg/day had significantly
low total nitrogen flux (Q), rates of total body pro-
tein synthesis (S), catabolism (C) and S/Q, as com'
pared with the controls. A reduction in daily protein
intake t0 0.6 g/kg/day resulted in marked increase
in all these parameters, approaching those of the con-
trols. In normal subjects, low protein intake did not
affect the total body protein turnover signfiicantly.
The results suggest that the adaptive response to res-
triction of protein intake is an efficient utilization of
nitrogen entering the metabolic pool for anabolic
purposes. This response becomes manifest and essen-
tialin patients with CRF and forms the basis for low
protein diet therapy. 相似文献

骨髓瘤肾病是多发性骨髓瘤的严重并发症之一,其死亡率仅次于感染。多发性骨髓瘤中肾病发生率约66%,男略多于女,年龄多在50岁以上。骨髓瘤肾病可在确诊骨髓瘤前一段时间发生,因而易误诊为原发性肾病,应引起注意。一、骨髓瘤肾病的发生与下列因素有关:1.轻链的肾毒作用:骨髓瘤细胞可产生大量免疫球蛋白,其中轻链分子量小,能经肾小球滤过,进入肾小管内形成管型,阻塞管腔,从而降低GFR。此外轻链可直接损害肾脏,高等电点轻链易引起肾脏损害;轻链糖化作用和聚合作用也可损害肾脏;轻链还可促进Tamm-Horsfall 蛋白(THP)沉淀形成管型,且THP 外渗至肾间质与钙及其他蛋白形成钙蛋白复合物,直接损害肾实质。2.骨髓瘤细胞直接损害肾实质。3.骨髓瘤引起电解质代谢紊乱: 相似文献

急性胰腺炎患者(主要是水肿型)经内科保守治疗后大多能获痊愈;但部分病例,尤其是病因不明或病因未能及时解除者,往往反复发作,最后导致胰腺组织破坏,纤维组织增生,钙化和萎缩,表现为胰腺内外分泌功能不全,严重影响患者的健康。目前对胰腺内外分泌功能的检查尚缺乏实用和简便的方法。本组应用口服葡萄糖-胰岛素释放试验和口服N-苯甲酰-L、-酪氨酰对氨基苯甲酰酸(N-benzoyl-L-tyrosyl-p-aminobenzoic acid,BT-PABA)胰腺功能试验(OPFT),分别测定33例复发性胰腺炎患者的内外分泌功能,结果报道如下。 相似文献

对本组肾病综合征患者,在活动期、缓解期和停药后所测IgG的平均值均明显低于正常对照组(P<0.01);而IgM较正常对照均明显增高(P<0.01)。与正常对照组比较,活动期和停药后,Tt百分率和绝对数在活动期无差异,停药后显著增加(分别为P<0.01、P<0.05);Tγ百分率和绝对数除活动期Tγ绝对数无差异外,其余均有非常显著增高(P<0.01);而Tμ百分率和绝对数,除停药后Tμ绝对数无差异外,余均明显降低;Tμ/Tγ活动期和停药后均有非常显著降低(P<0.01)。慢性肾炎肾病型患者低IgG血症可能由于Tμ细胞数量不足或其功能低下有关。 相似文献
