[Urinary tests for inflammation in glomerulonephritis]. / Mochevye testy vospaleniia pri glomerulonefrite.

Boyden camera tests, chemiluminescence of urinary supernatant, passive hemagglutination tests were used in measuring chemotactic properties of the urine, intensity of free-radical processes, fibronectin urine concentrations, respectively, in 31 glomerulonephritis (GN) patients. The above parameters were closely related to nephritis activity. These were much lower in patients with nephritis remission, than in subjects with nephrotic syndrome or exacerbation of latent nephritis. Chemotactic activity and intensity of free-radical processes were unrelated to protein urea which, however, correlated with fibronectin concentrations (r = 0.35, p < 0.05). The authors discuss the role of the mediators' values in evaluation of local renal inflammation and feasibility of their use as criteria of nephritis activity and prognosis.

[R proteins as a reflection of disorders in the cellular reception mechanisms in kidney diseases]. / R-belki kak otrazhenie narushenii mekhanizmov kletochnoi retseptsii pri zabolevaniiakh pochek.

As many as 47 patients with amyloidosis and 31 with chronic glomerulonephritis (CGN) were examined for the blood serum content of R proteins, chemotactic activity of blood leukocytes and the degree of the inhibitory influence of the autologous serum on chemotaxis. Amyloidosis and CGN were marked by an increase of the level of receptor proteins. A reverse correlation was established between the rise of the content of R proteins and the chemotactic properties of leukocytes. In CGN, the rate of demonstration of the high titers of R proteins and the magnitude of the chemotaxis decline depended on the disease phase (the degree of activity) whereas in amyloidosis, these reactions differed insignificantly in patients with various clinical patterns and stages of renal amyloidosis.

[Chemotactic function of skin fibroblasts in patients with amyloidosis]. / Khemotaksicheskaia funktsiia fibroblastov kozhi u bol'nykh amiloidozom.

Chemotaxis of cultivated fibroblasts, obtained from patients with amyloidosis, chronic glomerulonephritis and healthy volunteers, was investigated. Fibroblast migration toward donor serum and serum from patients with amyloidosis was measured using Boyden chamber's technique. As "zero" chemoattractant Hank's solution was used. It was shown, that chemotactic index (CI) was independent from cell density. Significant CI depression of fibroblasts from patients with amyloidosis toward donor serum in contrast to fibroblasts from patients with chronic glomerulonephritis and healthy volunteers was shown. The depression of chemotactic function was the same with fibroblasts from patients with different variants of amyloidosis and different stages of amyloid nephropathy and was stable in several cell generations. The results obtained suggest the existence of primary hereditary variant (variants) of chemotactic function, which may lead to the development of amyloidosis in certain conditions.

[The chemotactic characteristics of the leukocytes and fibroblasts in amyloidosis]. / Osobennosti khemotaksisa leikotsitov i fibroblastov pri amiloidoze.

Altogether 44 patients with amyloidosis (7 with primary, 24 with secondary and 13 with hereditary associated with periodic disease) and different stages of renal impairment and 32 patients with chronic glomerulonephritis (CGN) (14 with the latent and 18 with the nephrotic form) were examined for chemotactic properties of peripheral blood leukocytes and skin fibroblasts in Boyden's chambers. Chemotaxis of leukocytes from patients with different clinical forms of amyloidosis was found to be decreased. That decrease manifested itself even at the proteinuric stage of renal impairment. Addition of autologous serum brought about another decrease of the chemotactic response of leukocytes. There was a lowering of chemotaxis of cultivated skin fibroblasts from amyloidosis patients, which remained unchanged on repeated cell passages. Chemotactic activity of cultivated fibroblasts from CGN patients did not differ from that of healthy persons' fibroblasts and embryonal fibroblast strain. Possible causes of the alterations revealed are discussed.
