Проведена статистическая обработка сформированной базы данных показателей неспецифической резистентности MS «Excel» с целью изучения динамики иммунитета по параметрам бактерицидной, лизоцимной и фагоцитарной активности у крупного рогатого скота черно-пестрой породы разных возрастов. Было установлено, что средние значения показателей лизоцимной и бактерицидной активности у телят в 6 мес были ниже (47,89% и 49,09%, соответственно), чем у животных в 3—4 года (53,75% и 52,81%). Выведено уравнение регрессии, описывающее взаимосвязь между средними показателями фагоцитарной активности и возрастом при высокой степени достоверности (R2=0,90). Изменения лизоцимной и бактерицидной активности в зависимости от возраста были недостоверными (R2=0,58 и R2=0,49, соответственно). Установлена высокая корреляция между бактерицидной и лизоцимной активностью. Отмечена динамика изменения неспецифического иммунитета у коров различных возрастных групп. Создание баз данных и постоянный мониторинг основных показателей естественной резистентности в зависимости от различных факторов (породы, возраста, стадий лактации, кормления, способов содержания), которые влияют на данные показатели, необходимо для оценки физиологического состояния организма животных и их устойчивости к болезням. Statistical processing of the generated MS "Excel" on indicators of non-specific resistance database was carried out with the aim of studying the dynamics of the development of immunity in terms of bactericidal, lysozyme and phagocytic activity in black-and-white cattle of different ages. It was found that the average values of indicators of lysozyme and bactericidal activity in calves at 6 months were lower (47.89% and 49.09%, respectively) than in animals at the age of 3—4 years (53.75% and 52.81%). The equation of regression was derived, it describes the relationship between the average indicators of phagocytic activity and the age with a high degree of reliability (R2=0.90). The changes in lysozyme and bactericidal activity depending on age were dubious (R2=0.58 and R2=0.49, respectively). The high correlation between bactericidal and lysozyme activity was established. It was noticed that the cows of different age groups experienced the dynamics of changes in nonspecific immunity. The creation of databases and constant monitoring of the main indicators of natural resistance, depending on various factors (breed, age, stages of lactation, feeding, methods of keeping) that affect these indicators, is necessary for assessing the physiological state of the animals’ body of and their resistance to diseases.

The literature reviewed in this article suggests that breastfeeding positively influences cognitive development. Studies comparing the effects of early feeding methods on cognition consistently show mental test score advantages for breastfed infants over bottlefed subjects. Also, breastfeeding may function as a buffer against adverse developmental outcomes from early traumatic events such as low birthweight or neurologic insults. It is recognized that breastmilk contains long-chain polyunsaturated fatty acids that are necessary for the normal development of the retina and cerebrum. Yet, breastfeeding may not always promote optimal development in children. Infants breastfed by mothers using alcohol or marijuana have lower scores on developmental tests. Thus, while breastfeeding has the potential for contributing to the healthy development of infants, it may also be capable of transferring toxic substances known to interfere with normal development.

Feeding difficulties in older patients who are suffering from dementia present problems with balancing conflicting ethical principles. They have been considered by several writers in recent years, and the views of nursing and care staff have been studied in different contexts. The present study used focus groups to explore the way in which nursing and care staff in a National Health Service trust deal with conflict between ethical principles in this area. Three focus groups were convened, one each from the staff of three wards caring for patients with dementia. Case histories were discussed and transcripts analysed. It emerged that staff were aware of making fine judgements of utility concerning the spectrum of feeding methods available. Informants gave some weight to the principle of autonomy, but sought to balance that against their commitment to care. In explaining their perspectives, informants gave more weight to personal attitudes and trust culture than to professional ethics
