This study evaluated the relative occurrences of BK virus (BKV) and JC virus (JCV) infections in patients with chronic kidney disease (CKD). Urine samples were analysed from CKD patients and from 99 patients without CKD as a control. A total of 100 urine samples were analysed from the experimental (CKD patients) group and 99 from the control group. Following DNA extraction, polymerase chain reaction (PCR) was used to amplify a 173 bp region of the gene encoding the T antigen of the BKV and JCV. JCV and BKV infections were differentiated based on the enzymatic digestion of the amplified products using BamHI endonuclease. The results indicated that none of the patients in either group was infected with the BKV, whereas 11.1% (11/99) of the control group subjects and 4% (4/100) of the kidney patients were infected with the JCV. High levels of urea in the excreted urine, low urinary cellularity, reduced bladder washout and a delay in analysing the samples may have contributed to the low prevalence of infection. The results indicate that there is a need to increase the sensitivity of assays used to detect viruses in patients with CDK, especially given that polyomavirus infections, especially BKV, can lead to a loss of kidney function following transplantation.

Este estudo avaliou a resposta inflamatória aguda induzida por injeções de 0,5 mL de solução salina (controle), 500 µg de carragenina e 0,5 mL de tioglicolato a 3% na bexiga natatória de juvenis do híbrido tambacu. Os peixes foram distribuídos em três tratamentos, três repetições e aclimatados durante 10 dias antes do ensaio. A caracterização das células do exsudato inflamatório foi feita após coloração com Giemsa e PAS. Peixes injetados com carragenina apresentaram maior número de células no exsudato inflamatório do que com salina e tioglicolato. A porcentagem de trombócitos no exsudato foi maior nos injetados com carragenina quando comparada com a dos injetados com tioglicolato. Por outro lado, o percentual de granulócitos foi maior em animais injetados com tioglicolato do que em animais injetados com carragenina. A carragenina provocou maior migração de macrófagos para o foco inflamatório. O método de PAS confirmou a presença de três tipos de granulócitos: célula granular eosinofílica (CGE) tipo 1 com as características da célula granulocítica especial encontrada no sangue, CGE tipo 2, menor do que esta última, e de neutrófilos. Este estudo contribui para o melhor entendimento da resposta inflamatória e dos processos infecciosos em peixes nativos.

The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.
