Regulation and coordination of different body organs is important in multicellular organisms. Hormones and the nervous system participate in this synchronization. Hormones are the compounds and chemical messengers produced by cells, glands, or special tissues called the endocrine system and released into the bloodstream. In addition to the hormones, blood is consist of proteins, sugars, lipids, vitamins, etc. Blood sugar is glucose which produces energy in the body. Regular blood glucose levels vary at different ages and exceed 120-170 mg / dl. It is harmful and even fatal to increase or decrease it from the normal level, so the concentration of glucose dissolved in plasma was subject to tight regulation and various regulatory mechanisms were developed thereon. Hormones cortisol, glucagon, adrenaline, and glucocorticoids are the major regulators. These substances are tracked regularly to prevent blood glucose from rising and dropping. Insulin consists of hyperglycemia, as well as other hormones. The mechanism by which it affects the metabolism of the food (carbohydrates, lipids, proteins) prevents hypoglycemia in several respects.

Weaning is a critical period for the growth and development of mammals, in which various physiological and biochemical indicators of the body have undergone great changes. The development, differentiation, and maturation of the nervous system are regulated by many proteins. Changes in related proteins affect the physiological functions of the nervous system. However, the regulation of selfrenewal and differentiation of the nervous system at this stage is still poorly understood. The mechanism of differentiation and regulation of the major proteins in the nervous system during this special period of weaning remains to be investigated. Therefore, this paper aims to summarize the alteration of the nervous system during weaning and provide the basis for subsequent research.

An important direction in the improvement of veterinary and prophylactic measures is the development and introduction into production of new preparations having bioactive properties and regulatory influence on the growth and development of birds, the intensity of metabolic processes, the ability to enhance the functional activity of organs and systems of the body, increase the level of natural resistance of the organism animals. The purpose of research was to study the effect of nanomicroelement feed additive «Microstimulin» and means Bioglobin on the resistance and metabolism of chicken broilers at experimental pseudomonosis. The investigated means «Microstimulin» and Bioglobin were given to chickens aged 14 days (cross Cobb 500) per os 1 time per day in a dose of 1 ml/l and 1 ml/kg with drinking water for 14 days. At day 12 of the experiment, we infected chickens with culture P. aeruginosa intraperitoneally at a dose of 300,000 CFU/ml to modeled pseudomonas infection groups. Slaughter of chickens was carried out in accordance with the principles of humanity by decapitation method on the 15th day of the experiment in 29 day old chicks. The determination of action of the «Microstimulin» and Bioglobin on biochemical processes in the organism of conditionally healthy poultry and at experimental pseudomonas infection was carried out in a complex manner, based on the indicators of congenital immunity, protein metabolism and activity of hepatospecific enzymes AST and ALT. The «Microstimulin» and Bioglobin has a pronounced influence on metabolic processes, in particular protein metabolism, and on the state of the system of congenital immunity of poultry. In the organism of intact bird, investigated means causes similar changes in the level of such mediators of the immune response, as CIC average molecular weight and seromucoids. The use of «Microstimulin» induces pronounced changes in the level of the protein through increased globulin fractions, and increased lysozyme activity. The action of Bioglobin is accompanied by a redistribution of protein fractions towards a slight increase in the synthesis of albumin and γ-globulin, the accumulation of the protein metabolism fractions in the serum, and an increase of lysozyme activity. The investigated means also helps to reduce the manifestations of pathogenetic effects of P. aeruginosa on the bird organism.

The plant of castor is widely spread in the Iraqi land, and characterized with containing ricin toxin, which has a very serious effects, and because the seeds of this plant scattered in the agricultural soil and rivers water, which increases the exposure of humans and animals to these beans. Objective: This experiment was designed to study the effect of high concentration of castor bean powder in some physiological and biochemical parameters and changes in some tissues of the body, as well as trying to use doxycycline to reduce the effects of ingestion of these seeds. Materials and Methods: In the experiment, 24 local rabbits were raised and fed in the Animal House of the Faculty of Medicine / Al-Muthanna University, then divided into four groups and treated for three weeks (21 days), Control group: treated with normal saline solution (0.9) orally throughout the experiment, G1: was treated orally with a concentration of 25 mg / kg of castor bean powder daily during the experiment, G2 : orally treated 25 mg / kg of castor bean and 25 mg / kg of doxycycline, G3: orally treated 25 mg / kg of castor powder with 50 mg / kg of doxycycline daily throughout the trial period. Results: The results of the experiment showed significant changes (P less than 0.05) in all physiological and biochemical blood tests when compared with control group. There was a significant decrease in PCV, Hb, RBC, T.protein and body weights, while demonstrated a significant increase in WBC, Urea, Creatinine, ALT, AST and ALP, with distortions in liver and kidney of animals that treated with Castor beans. In contrast, the treatment with doxycycline and caster beans showed significant improvement reflected by a normal proportion in physiological tests and biochemical tests with improvement in the tissues when compared to control group. Conclusions: It can be concluded from this study that castor bean has high toxic and pathogenic effects that may be dangerous to the life of the organism. Therefore, it is advisable to be cautious of these pills and avoid exposure to them, also recommended to take high concentrations of doxycycline treatment when infected with castor bean poisoning.
