Induced tolerance to the pyrogenic action of group A streptococcus peptidoglycan decreased after one week and was no longer detectable after the second week. However, one or two further doses of peptidoglycan rapidly restored the tolerance. The passive transfer of plasma from rabbits tolerant to streptococcus peptidoglycan to nontolerant animals failed to transfer tolerance. Antiserum to streptococcus peptidoglycan neutralized the pyrogenic effect of not only streptococcus but also staphylococcus and pneumococcus peptidoglycan; it did not influence the febrile response to endotoxin. Histopathologic changes in the rabbit heart produced by the intravenous injection of staphylococcus or pneumococcus peptidoglycans were similar and were characterized by various stages of degeneration and necrosis. The changes were less pronounced than after streptococcus peptidoglycan. Antiserum to streptococcus peptidoglycan had modest or no counteracting effect on the development of heart alterations after staphylococcus or pneumococcus peptidoglycan. 相似文献

During a 7-mo period, mice from a group of 383 being used in a toxicology experiment developed severe progressive necrotic dermatitis, and some animals developed paralysis. The overall mortality rate for the group was 134/383 (35%). Seventeen mice were necropsied for bacteriologic and histopathologic examination. A streptococcus identified as Lancefield group G was isolated from the skin lesions of 15 of the mice, from 8 of 9 throats cultured, from 4 of 8 spleens, and occasionally from other sites. It was thought that the infections were initiated and perpetuated by bites from mice carrying the streptococcus in their mouth and throats. Microscopic examination of affected skin revealed necrotic dermatitis characterized by epithelial ulceration with suppuration. The skin lesions were reproduced in 6 of 15 mice inoculated with the isolated streptococcus. 相似文献

For treating Leishmania major infection in BALB/c mice, we used thalidomide in conjunction with glucantime. Groups of mice were challenged with 510(3) metacyclic promastigotes of L. major subcutaneously. A week after the challenge, drug treatment was started and continued for 12 days. Thalidomide was orally administrated 30 mg/kg/day and glucantime was administrated intraperitoneally (200 mg/kg/day). It was shown that the combined therapy is more effective than single therapies with each one of the drugs since the foot pad swelling in the group of mice received thalidomide and glucantime was significantly decreased (0.9 +/- 0.2 mm) compared to mice treated with either glucantime, thalidomide, or carrier alone (1.2 +/- 0.25, 1.4 +/- 0.3, and 1.7 +/- 0.27 mm, respectively). Cytokine study showed that the effect of thalidomide was not dependent on IL-12; however, it up-regulated IFN-gamma and down-regulated IL-10 production. Conclusively, thalidomide seems promising as a conjunctive therapy with antimony in murine model of visceral leishmaniasis. 相似文献

One hundred children with impetigo were studied with particular emphasis upon the organism causing the infection and associated renal complications. In 50 per cent of cases, Group A beta-hemolytic streptococcus grew on cultures of material from the lesions, and evidence of recent infection with this organism as shown by an elevation of antistreptolysin O titer was present in an additional 17 per cent of cases.Acute glomerulonephritis developed in three of the 66 children with bacteriologic or serologic evidence of streptococcal infection. Four other children in this group and nine children with staphylococcal impetigo had unexplained microscopic hematuria.All children with nephritis already had evidence of the disease when first seen. In most of those with unexplained hematuria, this condition was detected at the first visit. Hematuria developed in others while they were receiving systemic antibiotics. The significance of isolated microscopic hematuria is uncertain, but is seen often in association with cutaneous infection with both staphylococcus and streptococcus. Microscopic hematuria as defined is apparently not prevented by antibiotic therapy.If acute glomerulonephritis that follows streptococcal cutaneous infection is to be prevented, streptococcal impetigo will have to be treated promptly after onset. 相似文献

We sought to explore the relationship between renal lesion features and genetic mutations in tuberous sclerosis complex (TSC) patients. TSC patients with renal lesions were subjected to TSC1/2 gene next-generation sequencing (NGS). TSC1/2 mutation types and imaging examinations were screened for combined analysis of genetic and clinical features. Seventy-three probands among TSC patients with renal lesions were included. Twenty affected relatives were also included. In total, 93 patients were included. Eighty patients (86.0%) had bilateral renal angiomyolipomas (AMLs), and one had epithelioid AML. Two patients had polycystic kidney disease, one had renal cell carcinoma, and one had Wilms tumor. Among the 73 probands, four had TSC1 mutations, 53 had TSC2 mutations, and 16 had no mutations identified (NMI). There was no statistically significant difference between TSC1 mutation, TSC2 mutation and NMI group (P= 0.309), or between familial and sporadic groups (P= 0.775) when considering AML size. There was no statistically significant difference between pathogenic/likely pathogenic and benign/likely benign/NMI groups (P= 0.363) or among patients with different mutation types of TSC2 (P= 0.906). The relationship between the conditions of TSC gene mutations and the severity of renal lesions still needs more analysis. Patients with NMI, particularly those with familial disease, need more attention because the pathogenesis remains unknown. 相似文献

The effect on donor leukocyte migration of serum obtained from the patients with tuberculosis of the lungs, chronic pneumonia and healthy persons was studied after subcutaneous or intradermal injection of the microbial antigen (PPD, streptococcus and staphylococcus antigen). A factor inhibiting donor leukocyte migration appeared in the blood serum of sensitized individuals after the antigen injection. This factor proved to be localized in the serum fraction III obtained after the gel-filtration of sephadex G-200, and is sorbed by leukocytes. 相似文献

There are evidences that some drugs used for the human diseases can modify the biodistribution of radiopharmaceuticals. The N-methyl meglumine antimoniate, commercially known as glucantime (Rhodia, Brazil), is the elected drug for the treatment of all the clinical forms of leishmaniasis. As therapeutic drugs can present important toxic effects, we studied the effects of the glucantime on the kinetic of biodistribution of radiopharmaceuticals. To study the glucantime effect on the biodistribution of technetium-99m-methylenediphosphonic acid (99mTc-MDP), glucantime IM (80 mg/kg/day) was administered into male Wistar rats (3 months old age) in single dose during 7 days. 99mTc-MDP was injected 1 hr after the last dose. The animals (n = 24) were divided into two groups: treated (n = 12) and control (n = 12) and they were rapidly sacrificed, respectively, in 3 periods (5, 30 and 120 min) after administration of the 99mTc-MDP. The organs were isolated (brain, heart, thyroid, lungs, kidneys, testis, stomach, intestines, pancreas, spleen, liver, muscle, bone and bladder) and the percentages of radioactivity (%ATI) in each organ were calculated. The results were analyzed by the Wilcoxon test (p < 0.05). The analysis of the results has shown a significant increase of the %ATI after 5 min administration of the 99mTc-MDP in spleen, kidneys, testis, heart, liver and a reduction of %ATI in bladder. Thirty minutes after administration of the 99mTc-MDP, the analysis ofthe results reveals a significant reduction of the %ATI in femur, kidneys, thin bowel, lungs, heart, liver and an increase in abdominal muscle and stout bowel. One hundred-twenty min after administration of the 99mTc-MDP, the analysis of the results shows a significant reduction of the %ATI in spleen, thyroid, blood, femur, kidneys, liver and an increase in bladder, pancreas and lungs. Biochemical dosages were also performed before (control group, n = 12) and after (treated group, n = 12) treatment with glucantime. There was a significant (p < 0.05) decrease to the biochemical levels after the treatment with glucantime in following dosages: blood urea nitrogen, creatinine, alkaline phosphatase, lactic dehydrogenase, aspartate amino transferase, total creatine kinase, total protein, globulin and albumin. These results were compared with the control group, without glucantime, and statistical analyses were performed (t-student test, p < 0.05). These results could be associated with the biological effects and/or metabolization of the studied drug. 相似文献

A method for the assay of antibodies to the specific antigenic determinant of group A streptococcal polysaccharide (A-polysaccharide) in human sera was developed. The sera were tested in the precipitation test in agar gel with different doses of A-polysaccharide. The presence of a high level of the above-mentioned antibodies is indicative of infection caused by group A streptococcus, but not streptococci of other groups or by the L-forms of streptococci. In 87.5% of patients with primary rheumatism a high level of antibodies to the specific antigenic determinant of A-polysaccharide was detected during the first day of the disease, which confirms most convincingly the etiological role of group A streptococcus in rheumatism. Considerable differences in the level of antibodies to A-polysaccharide in the active and non-active phases of rheumatism have been established, which makes it possible to use the presence of a high level of these antibodies as an indicator of the rheumatic process activity. A considerable percentage of sera with a high level of antibodies to A-polysaccharide was also detected in erysipelas and acute glomerulonephritis patients. 相似文献

The aim was to confirm the influence of HLA Class II antigens on the progression of HCV infection and to assess the relationship between these antigens and histological damage, HCV viral load and HCV genotype. 143 patients were enrolled and divided into three groups. Group A included 34 anti-HCV positive, HCV-RNA negative patients with ALT persistently normal; group B included 39 patients with HCV-RNA positive and abnormal ALT level; group C included 70 normal subjects. Serological HCL typing was performed with lymphocytotoxicity test by Terasaky and McClelland, using lymphobeads HLC class II. The frequency of HLA DR11 (5) was significantly higher in the control group (52.9%) and in group A (64.7%), than in group B (28.2%). Allele HLA DR6 was demonstrated in a similar proportion (26%) among control group and group B, while HLA DR14 (6) was less frequent among controls (18% vs 1.4%). In group A the frequency of HLA DR14 (6) was 3% compared to group B, HLA DR17 (3) was prevalent (15.4%) in group B. Liver damage was associated with the detection of HLA DR14 (6) and HLD DR17 (3) antigens. Significantly lower levels of HCV-RNA were measured in subjects with HLA DR11 (5) than in these with either DR6 or DR17 (3). HLA class II antigens appear crucial for resolution or progression of HCV hepatitis. The punctual identification of these genetic factors may, therefore, prove to be useful in predicting disease evolution, in guiding the appropriate therapy for patients with poor prognosis, and in encouraging the development of now therapeutic strategies. 相似文献

ObjectivesTo assess whether patients’ willingness to add a blood pressure-lowering drug and the importance they attach to specific treatment characteristics differ among age groups in patients with type 2 diabetes.ResultsOf the 161 patients who completed the questionnaire, 151 (72%) could be included in the analyses (mean age 68 years; 42% female). Aged patients were less willing to add a drug than non-aged patients (67% versus 84% respectively; P = 0.017). In both age groups, the effect on blood pressure was most important for choosing a drug, followed by the risk of adverse drug events and the risk of death. The effect on limitations due to stroke was only significant in the non-aged group. The effect on blood pressure was slightly more important in the non-aged than the aged group (P = 0.043).ConclusionsAged patients appear less willing to add a preventive drug than non-aged patients. The importance attached to various treatment characteristics does not seem to differ much among age groups. 相似文献

The study aimed at elaborating the technique of an early diagnosis of cheiroarthropathy. The study involved 170 patients with diabetes mellitus type I aged between 16 and 45 years and disease duration ranging from 1 year to 33 years. Advanced cheiroarthropathy with shining waxy skin was diagnosed in 41 patients (group I). No lesions characteristic for cheiroarthropathy was diagnosed in 122 patients (group II) while in 7 patients (group III) only skin lesions without contractures were noted. Proliferative retinopathy was significantly more frequent (p less than 0.001) in the group with cheiroarthropathy--39% to 8%. Mean age of patients of group I is 31.5 +/- 5.9 years, in group II--31.0 +/- 6.6 years. Duration of diabetes mellitus is 17.8 +/- 6.2 and 9.6 +/- 7.2 years respectively (p less than 0.05). An angle of metacarpophalangeal joint of the V finger extension was measured in all patients with goniometer. A significant difference was noted in both groups: 34.4 +/- 8.08 degrees and 56.5 +/- 7.1 degrees, respectively (p less than 0.01). Mathematic models were designed basing on the value of measured angle and duration of the disease. These models facilitate possible risk of cheiroarthropathy. Systematic measurements of metacarpophalangeal joint extension seems valuable means of early diagnosis of diabetic cheiroarthropathy and follow-up of such patients. 相似文献
