BACKGROUND Perinatal viral infections of fetus are among the leading causes of congenital cataract and identifying the viral etiology is important. OBJECTIVES To detect the presence of Rubella virus (RV), herpes simplex virus (HSV) and cytomegalovirus (CMV) in lens aspirate specimens obtained from patients with congenital cataract and relate the results with serology. SETTING AND DESIGN Pro...

an enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. immunoglobulin fractions were purified and coated on wells of microtiter plates. a chain heterology was introduced in neopterin derivative and conjugated to penicillinase. the assay is...

Apoptosis and the genes regulating this process have recently become a focus of interest in the study of cancer development and progression. Both Bcl-2 and Bax are transcriptional targets for the tumor supressor protein, p53, which induces cell cycle arrest or apoptosis in response to DNA damage. The coordinate performance of these molecules is crucial for controlling life or death of a cell. C...

OBJECTIVES To determine and identify, unequivocally, if plasma kallikrein (PK) is present in the synovial fluid of patients with rheumatoid (RA), psoriatic (PA) and osteo (OA) arthritis, and to consider its functional importance in the inflamed joint. METHODS Therapeutically aspirated synovial fluids (pooled and individual samples, n = 66) were obtained from patients with arthritis. In additi...

OBJECTIVE Lyme borreliosis is characterized by strong inflammatory reactions probably due to the presence of Borrelia burgdorferi in the joint. It has been suggested that Borrelia induces the immunological mechanisms that either can amplify the inflammatory response or can suppress it. To reveal the underlying mechanisms of chemoattraction and activation of responding leukocytes, we investigate...

BACKGROUND Although many experimental studies provide convincing evidence that type II immunity is protective against helminths, recent data in mice demonstrate that Th1 is also important in some cestodes like Hymenolepis nana. OBJECTIVES To identify the role of Th1 and Th2 lymphocytes in immunity against H. nana, the levels of IL-12, IFNgamma, IL-5, and IL-13 were determined in serum of huma...

The objective of this study was to determine seroprevalence of small ruminant lentivirus (SRLV), Brucella abortus and Brucella melitensis infections among dairy goats in South Backa and Srem region in Vojvodina Province. The other aim was to determine the risk factors associated with SRLV infection in investigated herds. A total of 971 serum samples were collected from 8 comercial dairy goat he...
