[Identifing relationships among acute phase proteins [Hp and Fb], albumin and clinical findings in dairy calf pneumonia]

Enzootic calf bronchopneumonia is a multyfactorial disease that occurs in association whit the in telaction of various infectious agenes, and colf susceptibility. The economic losses is associated with death loss and treatment costs, reduction of live weight gain and reduced of productive life span, whith mey be considevable. The aim of this study was to examine the acute phase response in calves with enzootic pneumonia. We measured acute phase proteins [App] and identified some potential markers useful for evaluation of calve's health status. Sixty Holstein calves within two weeks to six months old were divided into two groups. Clinical findings of individual were recorded after the physical examination. Blood samples were taken from the calves and were used for Complete blood count [CBC] and serum biochemical evaluation. Clinical findings including body temperature, pulsation, and respiratory rate were significant between two groups. Hematological parameters showed no significant differences between two groups as well as some biochemical profiles [albumin and globulin]. The results of this study indicated a significant increase in Haptoglobin [Hp] and Fibrinogen [p<0.05]. Our results showed the application of Haptoglobin and fibrinogen measurements as indicators of health in calf herds, thereby facilitating treatment decisions

[Effects of eucalyptus globules labill essential oil on some immunological variables of common carp [cyprinus carpio]]

Influence of both dietary and bath administration of Eucalyptus globules labill was evaluated on some immunological variables of common carp [Cyprinus carpio] under temperature less than optimum in order to determine stimulatory effect of the essential oils. Fish weighing 30-35 g were bathed or fed with different doses of 30, 60 and 120 micro/L or mg/kg feed for a period of 8 days. Serum lysozyme activity, bactericidal activity, total white blood cells, total protein, globulin and albumin were measured on days 1, 2, 8, 15 and 23 after the essential oils administration. On day 23 post administration the remaining fish from each group were intraperitonealy injected with killed Aeromonas hydrophila [6x10[8] cells/ml] and antibody titer was measured 3 weeks later. The obtained results showed that Eucalyptus globules had a limited immunostimulatory effect on these immunological variables although antibody titers and total white blood cells in some test groups were significantly [p<0.05] higher than the control one. The reduction of the immunological factors is probably related to the lower water temperature, inappropriate administrating dose and duration of essential oils administration
