The ability to identify factors responsible for disease in all species depends on the ability to separate those factors which are environmental from those that are intrinsic. This is particularly important for studies on the development of the adaptive immune response of neonates. Studies on laboratory rodents or primates have been ambiguous because neither the effect of environmental nor mater...
Neurological disorders are among the main clinical problems affecting preterm children and often result in the development of communication and learning disabilities later in life. Several factors are of importance for brain development, however the role of immunoglobulins (passive immunity transfer) has not yet been investigated. Piglets are born agammaglobulinemic, as a result of the lack of ...
The 'endocannabinoid (CB) receptor (ECBR) system', consists of specific receptors and several endogenous ligands. The ECBR system is involved in many physiological functions including immunity, inflammation, neurotoxicity and neurotrauma, epilepsy, depression and stress, appetite, food intake and energy homeostasis, cardiovascular regulation, reproduction, and bone remodeling. The brain and gas...
The importance of colostrum for the growth and health of newborn offspring is well known. In bovine colostrum, the antibody (immunoglobulin) complement system provides a major antimicrobial effect against a wide range of microbes and confers passive immunity until the calf's own immune system has matured. Bovine serum and lacteal secretions contain three major classes of immunoglobulins: IgG, I...
Current evidence suggests that neonatal tolerance to a foreign Ag is the consequence of IL-4-mediated Th2 immunity rather than the thymic deletion of Ag-specific T cells. Here, we addressed the role of IL-4 in neonatal tolerance by testing whether tolerance to a minor histocompatibility Ag can be induced in newborn mice that lack IL-4 (IL-4(-/-)). We found that IL-4 does not play a dominant rol...
garlic and onions as dietary constituents and medicines have been used for many disorders which dates back to the early civilization. it has been shown that different species of allium have immunomodulating effects. in this study, we sought to determine if methanolic and chloroformic extracts of allim fistulosum l. (leek) have any effect on cell-mediated immune response in mice. methanolic and ...
The rate of degradation, organ deposition, and blood clearance of SBSA, SRSA, and IRSA has been measured in the newborn, 6-, and 30-day-old rabbits. When the animals were injected with a weight-graded dose of the 3 proteins, differences in their catabolism in the newborns were demonstrable as compared to the 6-, and 30-day-old animals. The capacity to degrade the azo compounds was shown to be i...
The glucocorticoid (GC) receptor (GR) mediates the effects of physiological and pharmacological GC ligands and has a major role in cutaneous pathophysiology. To dissect the epithelial versus mesenchymal contribution of GR in developing and adult skin, we generated mice with keratinocyte-restricted GR inactivation (GR epidermal knockout or GR(EKO) mice). Developing and early postnatal GR(EKO) mi...
conclusions treatment of neonatal respiratory failure with high rate mechanical ventilation may reduce some complications. results intraventricular hemorrhage (ivh) and air leak (e.g. pneumothorax) were less in hfppv group than conventional group (p = 0.012 and p = 0.038). the mean time needed for mechanical ventilation was lower in hfppv group, but this difference was not statistically signifi...
