“…The main reason for pathological change in theileriosis is progressive anemia and related disorders (3,(7)(8)(9). Increased fragility and oxidative damage in erythrocytes, damage to erythrocytes by parasites in the reticuloendothelial system, autoimmune reactions, and intraerythrocytic piroplasms contribute to the development of anemia (7)(8)(9).…”

Pure poly (ethylene oxide) (PEO) films and PEO-FeCl 3 films of various concentration were prepared and studied for thermal and optical properties. Various analytical techniques like XRD, EDX, SEM, TGA, and UV were used to examine the structural properties of PEO and PEO-FeCl 3 systems. X-ray scans (XRD) revealed the existence of some crystalline part in the PEO matrix. The concentration of FeCl 3 has a great effect on the crystallinity of PEO. Thermogravimetric analysis (TGA) data established that accumulation of FeCl 3 to PEO films enhanced the thermal stability of PEO. The optical properties of these systems were also studied in the UV-Visible region as a function of FeCl 3 concentration at room temperature.The obtained data were analyzed in terms of absorption formula for non-crystalline materials. From the measured absorption data optical energy gaps (E opt) were determined. The optical energy gap was found to decrease with the increase in FeCl 3 concentration, which indicates that FeCl 3 concentration had a significant influence on optical energy band gap. The absorption coefficient increased sharply at concentration of FeCl 3 (5%) wt as compared with the pure PEO.

“…In a previous report , the level of plasma vitamin E showed a minimum value when PCV decreased to its minimum value in anemic cattle infected with T. sergenti [19]. More recently, methemoglobin (MetHB), which is an oxidized form of hemoglobin, increased according to the onset of anemia [14], and also decreased in erythrocyte GSH and G-6-PD after T. sergenti infection (unpublished data). In the present study, the oxidative condition of erythrocyte membrane proteins in T. sergenti infection was investigated in order to elucidate the pathogenesis of this anemia.…”

“…The oxidation of inner surface proteins (skeleton) occurs in T. sergenti infection suggests the increase in oxidizing radical productions, and/or the deficient of antioxidant system occur in erythrocytes. In a previous study, it was shown that an increased MetHB concentration in T. sergenti infection coincided with anemia [14]. Although the reason for the enhancement of erythrocyte oxidation was not clear, the oxidation of membrane cytoskeleton may causes both structural and functional defects [1], and oxidized erythrocytes may be destroyed easily by erythropagocytosis [3].…”

ABSTRACT. As a part of the elucidation of the pathogenesis of anemia in Theileria sergenti infection, oxidized-erythrocyte membrane proteins (OEMPs) collected from T. sergenti-infected calves were examined. The amount of OEMPs were seen to increase with the progress of the anemia and showed a maximum value around the crisis period of the infection. The increase of OEMPs coincided with band N os. 1, 2, 2.1, 3, 4.1, 5, 6, and 7. The majority of them was located at the Triton X-100 un-extractive phase, and was confirmed as cytoskeletal proteins. This evidence indicates the enhancement of erythrocytic oxidation, and suggests that it might be one of the aggravati ng factors of anemia in T. sergenti infection.
