[Analysis of the electrical charge of albumin in idiopathic nephrotic syndrome by isoelectric focusing].

The state of the electrical charge of serum and urinary albumin was investigated in both the nephrotic and remission stage of idiopathic nephrotic syndrome (INS), using isoelectric focusing (IEF). 1) Both a b2 band (a main albumin band appearing at the site of isoelectric point: pI 4.7), and a b3 band (a more anionic albumin band than the b2 band) were detected commonly in all samples of urine and serum of INS patients in nephrotic and remission stages and of healthy volunteer controls even if the applied albumin in urine and serum amounted to 20 micrograms or 100 micrograms. 2) When applied albumin amounted to 20 micrograms, b1 bands (less anionic albumin bands than the b2 band) were detected between pI 4.7 and pI 6.5 in urine and in both serum and purified albumin fractionated from serum of INS patients in the nephrotic stage. However, b1 bands were not detected at all in the urine and serum of either INS patients in remission stage and healthy volunteer controls. 3) When applied albumin amounted to 100 micrograms, b1 bands were detected also in serum of healthy volunteer controls. From these results, it was confirmed that less anionic albumin existed also in the serum of healthy volunteer controls although the amount was extremely small.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term follow-up of a paediatric case of lipoprotein glomerulopathy.

A paediatric case of lipoprotein glomerulopathy, a new kidney disease characterized by glomerular lipoprotein thrombi, is reported. The patient had massive proteinuria from the age of 8 years, when the nephrotic syndrome was first detected. This was resistant to conventional treatment for more than 10 years. During the course of the disease, the hyperlipidaemia characteristic of hyper-pre-beta-lipoproteinaemia and elevation of apoprotein E persisted, and renal function gradually deteriorated. The renal histopathological findings from four biopsies were essentially the same, with storage of beta-lipoprotein in dilated, balloon-like glomerular capillary lumina. However, the number of glomeruli showing global sclerosis increased and tubulo-interstitial changes progressed in parallel with the gradual clinical deterioration. As in other cases reported in Japan some familial involvement has been noted.

[Malignant fibrous histiocytoma of the thoracic region].

A clinicopathological investigation of five malignant fibrous histiocytoma (MFH) in the thoracic region was performed. They were two cases of metastasis to the lung and 1 each of the primary lesion in the lung, chest wall and sternal region. This tumor usually occurs on the extremities, in the abdominal cavity or the retroperitoneal areas, so instances of its arising in the thoracic region, except for metastatic episodes, are considered to be rare. Tumors in 4 cases were excised surgically, while one was inoperable. On light microscopy, the lesions were found to be composed of two types of neoplastic cells, fibroblast-like cells and histiocyte-like cells, showing the characteristic histologic pattern of storiform and pleomorphic. Electron-microscopically, these two types of cells were discriminated according to the quantitative and quantitative differences of the various intracytoplasmic organelles. The histogenesis of malignant fibrous histiocytoma has been commonly considered to be the histiocytic cell derived from the bone marrow. However, more detailed pathological investigations are necessary.
