The aim of this study was to investigation on effects of in ovo administration of ghrelin on leukocytes count and heterophil/ lymphocyte (H/L) ratio in hatched chicks. 250 fertile eggs were divided to 5 groups; control or group 1 (without injection), group 2 (in ovo injected with 50 ng ghrelin at day 5), group 3 (in ovo injected with 100 ng ghrelin at day 5), group 4 (in ovo injected with 50 ng...

The response to intravenous challenge with sheep erythrocytes was determined in Sprague-Dawley rats following autotransplantation of splenic tissue into the subcutaneous tissue, peritoneal cavity, or a surgically created omental pouch. There was a marked rise in heterophil antibody titer following intravenous challenge in ten control animals, and no rise in titer in nine of ten asplenic animals...

Positive troponin test results in peripheral blood can be detected either during myocardial injury or from falsely positive test results. In this report, we present the positive results of a troponin test in a 24-year-old pregnant woman referred to the emergency department with atypical chest pain, and the clinical algorithm that we used to make the correct diagnosis. This patient presented wit...

Adherence of chicken heterophils was evaluated at 37 C using preconstructed columns containing various weights of nylon fiber (75 mg, 100 mg, or 125 mg) and whole blood anticoagulated with sodium heparin or 10% disodium ethylenediamine tetraacetic acid (EDTA). Additionally, 50-mg and 75-mg nylon fiber columns incubated at 41 C were used to evaluate heterophil adherence at an increased temperatu...

this experiment was conducted to compare the effects of multi-strain probiotic inclusion levels on performance, intestinal morphology, gut microflora and hematological changes in salmonella typhimurium (st) infected broiler chickens. a total of 120 day old ross 308 broiler chickens were distributed into 20 floor pens and reared for 10 days under 5 experimental treatments including a corn-soy ba...

The purpose of this study was to analyze the effect of auditory enrichment (by means of classical music) or physical enrichment (by means of hanging colored string bunches and barley grains on the floor) on tonic immobility duration, heterophil to lymphocyte ratio, and fluctuating asymmetry (FA) in chicks of several layer breeds. In experiment 1, 192 chicks from 8 Spanish breeds and 1 White Leg...

The purpose of this study was to analyze the associations among fluctuating asymmetry, duration of tonic immobility, heterophil-to-lymphocyte ratio, and one-legged standing, crooked toes, or footpad dermatitis in chickens. In experiment 1, cocks (n = 96; 36 wk old) from 11 Spanish breeds and a White Leghorn population that showed one-legged or normal standing were used. There were no significan...

Interleukin-2 (IL-2) exercises an array of biological effects on many cells including the functional activation of cells of the innate immune response. Heterophils, the avian equivalent of the neutrophil, function as professional phagocytes to aid in regulation of innate host defenses. The objective of the present studies was to examine the effects of recombinant chicken IL-2 (rChIL-2) on funct...
