TL;DR: In this paper, the authors found that onion and garlic caused an increase in the level of plasma triglyceride which could be due to insulin like activity of dietary alliums and other factors that promote lipogenesisi in growing stages.
Abstract: Dietary onion and garlic caused an increase in the level of plasma triglyceride which could be due to insulin like activity of dietary alliums and other factors that promote lipogenesisi in growing stages. Changes in the plasma triglyceride level in the control group due to change in age and sex were also noted. The triglyceride level was more in female birds when compared to males of similar age group. The plasma trigelyceride level increased with age in both sex except for the level being similar in the 6 and 9-week old females and 3 and 6-week old male birds. The results suggest that the effects of alliums in growing and adult stages may be different which needs further study.

TL;DR: It is concluded that the quail ovary possesses a NO/NOS system, and that NO may be considered as a mediator involved in various ovarian processes, including atresia.
Abstract: In the present study, nitric oxide (NO)-related substances, namely NO synthase (NOS), L-citrulline, cGMP and nitrotyrosine, have been localized in the quail ovary, using NADPH-diaphorase staining and immunohistochemical methods. The results indicate the presence of the NOS isoforms, showing distinct cell-specific distribution patterns in the quail ovary. Inducible NOS is primarily present in leukocytes, endothelial NOS in granulosa cells, and neuronal NOS in nerve cells, oocytes, interstitial cells and granulosa cells of pre-hierarchal follicles and of the germinal disc region of pre-ovulatory follicles. NOS activity, indicated by the presence of L-citrulline, is observed in oocytes, nerve cells, interstitial cells and a few granulosa cells of pre-hierarchal follicles. Detection of accumulated cGMP indicates that granulosa cells of pre-hierarchal and of pre- and post-ovulatory follicles, the theca interna of pre-ovulatory follicles, and oocytes are main targets of NO. Nitrotyrosine, a marker of peroxynitrite activity, is mainly localized in atretic follicles and in post-ovulatory follicles. It is concluded that the quail ovary possesses a NO/NOS system, and that NO may be considered as a mediator involved in various ovarian processes, including atresia.

TL;DR: The usefulness of Japanese quail in avian genetic and physiological studies has been demonstrated and single male mating pens consisting of several females should be used to obtain useful records from genetic studies.

TL;DR: The results showed that this isolate is pathogenic for quails above 3 weeks of age, and similar to those of adenovirus-induced inclusion body hepatitis.
Abstract: Quail (Coturnix coturnix japonica) and broiler (Gallus domesticus) chicks were inoculated experimentally with IBH virus (avian adenovirus-1) derived from quails to determine its pathogenicity. Quail chicks were inoculated by the intraperitoneal route at 3, 4, 5, 6 or 7 weeks of age. Lesions were encountered most frequently in the liver, kidneys and lungs. These included pale, swollen and mottled liver, swollen nephrotic kidneys, and congested and pneumonic lungs. The lesions were severe in birds inoculated at 5 weeks of age. Large basophilic intranuclear inclusion bodies were seen in hepatocytes and occasionally in the renal epithelium. The results showed that this isolate is pathogenic for quails above 3 weeks of age. Broiler chicks were inoculated at 4 weeks of age by the intraperitoneal route. The lesions produced in these chicks were similar to those of adenovirus-induced inclusion body hepatitis. Viral antigen was also demonstrated by dot-ELISA in suspension of liver tissue from both quail and broiler chicks.

TL;DR: The distribution of IL-1RI suggests that a role forIL-1 in sickness behavior is conserved in birds, but that roles in other putative mammalian functions (e.g. hypothalamic-pituitary-adrenal and gonadal axes regulation, transport through barrier-related tissues, arousal) may differ.
Abstract: Interleukin 1 isoforms (IL-1) are major regulators of vertebrate immune responses. In the mammalian CNS, this function is reflected in physiological and anatomical evidence implicating IL-1 in a suite of behaviors associated with sickness. Although birds show sickness behavior, a parallel role of IL-1 in birds has not been investigated. As proinflammatory effects of IL-1 are mediated via the IL-1 type I receptor (IL-1RI), we investigated the distribution of IL-1RI protein and mRNA after lipopolysaccharide challenge in brains of two avian species, the chicken and Japanese quail. In some respects, the neuroanatomic distribution of IL-1R mRNA and protein in chicken and Japanese quail resembled that reported in mammals and was consistent with its putative role in the physiology and behavior of sickness. For example, we found IL-1RI mRNA or IL-1RI immunoreactivity in lemnothalamic visual projection areas of the pallium, surrounding blood vessels in pallial areas, in the dorsomedial nucleus of the hypothalamus, in the nucleus taenia, in cerebeller Purkinje cells and the motor components of the trigeminal and vagus nuclei. However, in contrast to mammals, we did not find evidence of IL1-RI receptors in medial or lateral pallial structures, paraventricular nucleus, areas homologous to the arcuate nucleus, the choroid plexus, organum vasculosum of the lamina terminalis or the reticular activating system. The distribution of IL-1RI suggests that a role for IL-1 in sickness behavior is conserved in birds, but that roles in other putative mammalian functions (e.g. hypothalamic-pituitary-adrenal and gonadal axes regulation, transport through barrier-related tissues, arousal) may differ.
