Objective: sIL-2Rα is used as a marker for different malignancies in human medicine. The aim of this study was to show if sIL-2Rα is detectable and if there is any correlation to different diseases in dogs. Methods: For this purposes sIL-2Rα concentrations in the blood were measured in healthy dogs, in dogs with different non-neoplastic diseases and benign tumors and in dogs with malignant tumors. Serum levels of sIL-2Rα were measured by using a human specific enzyme linked immunosorbent assay (ELISA). Results: Measurement of sIL-2Rα was successful in most of the samples. Dogs with diseases have significantly increased serum levels of sIL-2Rα compared to healthy controls. sIL-2Rα serum levels are higher in patients with non-neoplastic diseases and benign tumors than in those with malignant neoplasia. There is a strong correlation between sIL-2Rα and leukocyte count. Conclusion: Measurements of sIL-2Rα in serum may be helpful in detecting stages and grades of inflammation in the progression of disease. sIL-2Rα could actually not be used as an indicator for malignant diseases in dogs like in humans. The strong correlation between sIL-2Rα and the leukocyte count indicates the inflammatory response to the disease. This could be helpful in giving a prognosis in some cases, because the inflammatory reaction is of prognostic relevance in different diseases including malignant and non-malignant neoplasia. Although the results of our research studies were very promising, further studies should be performed with a canine ELISA.展开更多

Methods: Thesoluble interleukin-2 receptor (sIL-2R) level in serum was analyzed by ELISA and Na^+ -K^+ -exchanging ATPase activi-ty in semen by phosphorus (Pi) assay. Results: The slL-2R level in serum was significantly higher and the Na^+ -K^+ -exchanging ATPase activity in semen significantly lower in AsAb positive infertile men when compared with thecontrols. Conclusion: The AsAb titer varies with the slL-2R level in serum. A decrease in Na^+ -K^+ -exchangingATPase activity in semen may play a role in male infertility caused by AsAb.展开更多

Methods: Forty-four patients with SLE were randomly divided into conventional corticosteroid treated group (control group, n =20) and conventional treatment group with leeching intervention added (leeching group, n =24). Before and after treatment the concentration of plasma endothelin (ET) and soluble interleukin-2 receptor (sIL-2R) were determined. Results: Before treatment the level of plasma ET and sIL-2R in the SLE patients were all higher than those in the normal healthy group, ( P <0.01). But after treatment the level of these in both groups were significantly improved than those of before treatment ( P <0.05), and comparison between these two treated groups showed that the difference between them was significant ( P <0.05). Conclusion: Leeching added to conventional treatment of SLE could be more effective in improving the level of plasma ET and sIL-2R, and ameliorating the impairment of renal tissues.展开更多

The changes of interleukin-2 (IL-2) and soluble interleukin-2 receptor (IL-2R) during heart valve (s) replacement operation and effects of aprotinin on them were observed. Twenty patients undergoing heart valve (s) replacement were randomly divided into two groups: control group (n=10) and apro- tinin group (n=10). In aprotinin group, 1 000 000 KIU aprotinin was given by vein injection and then 2 000 000 KIU was given as a bolus in prime. Blood samples were collected before CPB, right after CPB and on the 1st, 3rd and 7th postoperative day (POD) for serum IL-2 and sIL-2R determination. Results showed that after CPB, IL-2 was reduced and slL-2R increased. Meanwhile, serum IL-2R was lower in aprotinin group than that of control. It is concluded that the immunity depression after CPB is associated with low level of IL-2 and high level of sIL-2R and aprotinin can ameliorate the situation.展开更多

Type 1A diabetes is characterized by the presence of the anti-glutamic acid decarboxylase antibody (anti-GADab). Fulminant type 1 diabetes is classified as type 1B diabetes, and characterized by the absence of anti-GADab, flu-like symptoms, and elevated serum exocrine pancreatic enzymes. We report a type 1 diabetic patient who showed flu-like symptoms, elevated serum exocrine pancreatic enzymes, and an extremely high-titer of anti-GADab, manifesting the characteristics of both type 1A and fulminant type 1 diabetes.展开更多

The results showed that the plasma sIL-2R levels in patients with CAHB and SHB were much higher than those in normal controls (P < 0. 01 ), and the level ofplasma sIL-2R in patients with SHB was greatly higher than that in patients with CAHB. These results suggest that there is close relation between plasma level of sIL-2R, the clinical types of hepatitis B,and the severity of liver damage. In addition, there is no significant difference in plasma levels of sIL-2R between acute severe hepatitis B (ASHB), subacute severe hepatitis B (SASHB), and chronic severe hepatitis B (CSHB). No relation was found between sIL-2R level and hepatitis B virusreplication activity.展开更多

文摘Plasma levels of soluble interleukin-2 receptor (sIL-2R) in patients with chronic active hepatitis B (CAHB) or severe hepatitis B (SHB) were measured quantitatively by 'sandwich' ELISA with monoclonal antibodies in order to explore the change of sIL-2R levels, its clinical significance,and its relation to liver damage. The results showed that the plasma sIL-2R levels in patients with CAHB and SHB were much higher than those in normal controls (P < 0. 01 ), and the level ofplasma sIL-2R in patients with SHB was greatly higher than that in patients with CAHB. These results suggest that there is close relation between plasma level of sIL-2R, the clinical types of hepatitis B,and the severity of liver damage. In addition, there is no significant difference in plasma levels of sIL-2R between acute severe hepatitis B (ASHB), subacute severe hepatitis B (SASHB), and chronic severe hepatitis B (CSHB). No relation was found between sIL-2R level and hepatitis B virusreplication activity.
