Young apple trees that are planted in areas with limited water resources face challenges in their early growth stages. Insufficient intake of moisture often stunts the growth of the young tree and impacts its subsequent growth. In this study, we observed the interaction of semi-vigorous Marubakaido (Ma) (Malus prunifolia
„Ringo‟) and dwarfing Jm7 („Marubakaido‟ × M.9) rootstocks, water treatments (50% and 70% soil water content) and soil treatments (water retention substances) on young „Miyabi Fuji‟ apple trees and how this interaction impacts their growth under dry climactic conditions. The development of shoots, stems and roots was analyzed. The results showed that the interaction of rootstock and water and soil treatments had
a significant impact on total shoot length (p < 0.01), as did the interaction of rootstock and soil treatment on the length of the top three shoots (p< 0.05) and trunk fresh weight (p < 0.05). In addition, it was found that the interaction of water and soil treatments impacted shoot fresh weight (p < 0.05). This study revealed that the growth of young apple trees in areas with limited water resources can be aided by providing a 70% and 50% saturation of water and soil retention treatments for young trees that have been grafted onto semi-vigorous Ma and dwarfing Jm7 rootstocks. Growers in these areas should think about which rootstock to use, what soil water retention treatments that can be introduced into the soil as well the amount of water that should be applied.
The study of the course of non-traumatic intracerebral hematomas, including in the age aspect, is one of the significant areas of modern stroke, since it allows to choose the optimal treatment tactics for each group of patients. We have studied and presented in this article the clinical manifestations and features of the course of hemorrhagic stroke in 98 patients, divided into age groups - young, middle, elderly and senile. The study revealed some differences in the course of pathology in patients of different ages.

Purpose — to determine the values of central corneal thickness (CCT) in children depending on the level of intraocular pressure
(IOP) and the stage of congenital glaucoma (CG).
Material and methods. Clinical studies were carried out in the eye department of the clinic at the Tashkent Pediatric Medical In-
stitute. The study involved 18 patients (36 eyes) aged 9 to 11 years (mean age 9.3±1.6 years) with confirmed diagnosis of CG.
All patients underwent basic ophthalmologic examination prior to surgical and conservative treatment. In addition to basic meth-
ods, axial eye length and CCT were determined using an automatic non-contact tonometer/pachymeter manufactured by NIDEK
(USA).
Results. Analysis of the obtained data showed that in initial, moderate and advanced stages of glaucoma, the CCT values were sig-
nificantly lower than the age norm values. This indicates stretching of the fibrous capsule and thinning of the cornea in glaucoma.
In terminal stage CG, the CCT values practically did not differ from the age norm, but were higher than in initial, moderate and ad-
vanced stages of the disease. The noted thickening of the corneal membrane in terminal stage may be explained by edema of the cor-
neal tissue as a result of elevated IOP.
Conclusion. The age norm values of CCT should be taken into account when characterizing the severity of glaucomatous process
in children. Compared to the age norm, the cornea is significantly thinner in children aged 9 to 11 years with initial, moderate
and advanced stages of CG, and becomes significantly thicker in terminal stage, which is associated with edema caused by ele-
vated IOP.

“Anesthesiology and resuscitation is one of the most complex and difficult specialties, requiring a wide range of intelligence, deep knowledge and dexterity from the doctor at the same time.” Improving the pediatric resuscitation service and improving the quality of care for children in critical condition is one of the main directions of the healthcare organization of the Republic of Uzbekistan. Regardless of the location of the patient, the availability and quality of medical care at the resuscitation stage of treatment often determines the outcome of the underlying disease. Due to significant differences in the nature of anatomical and physiological characteristics and pathological processes, critical situations occur more often in children than in adults. “A child is not a miniature adult; his body has its own anatomical and physiological characteristics and throughout childhood undergoes characteristic age-related changes.” The anatomical and physiological characteristics of the child’s body are one of the main factors that determine the etiology of the process in children, the mechanism of development and the outcome of a critical condition. In pediatrics, a classification is widely used to describe the anatomical and physiological characteristics of the child’s body, where childhood is divided into six periods: 1. Infant period (neonatal period) – up to 4 weeks. 2. Breastfeeding period – from 4 weeks to 1 year. 3. Preschool (kindergarten) period – from 1 to 3 years. 4. Preschool period – from 3 to 6 years. 5. Junior school age (from 7 to 11 years). 6. Senior school age (from 12 to 18 years). Intensive care and resuscitation is one of the most important sections of such scientific and practical areas as anesthesiology and resuscitation. The practical methods of our specialty (respiratory support, transfusion and infusion therapy, tracheal intubation, nutritional support, efferent detoxification methods, etc.) are the same as the organization of services in most healthcare institutions.
On the first day, the PBP circadian rhythm mesors did not differ from the normative indicators in all age groups. During the period of toxemia, changes in the mesor of the circadian rhythm of PBP occurred in a wave-like manner with a period of fluctuations in group 1 – 9,6,5,5,6 days, in group 2 – 8,4 days, in group 3 - 5,4,4,5,6,5 days. Daily changes in the PBP circadian rhythm prevailed at a later date (in group 1 after 14 days, in group 2 - on day 8, in group 3 - after 14 days of toxemia), which suggests that one of the factors leading to hemodynamic disturbances is insufficiently effective anti-inflammatory, correcting hemodynamic function therapy. The most active compensatory hemodynamic reactions were revealed at the age of up to 40 years. The most pronounced tendency to destabilize hemodynamics was found in patients over 61 years of age at a later date (3-4 weeks) of the period of burn disease toxemia.
Time of planting is a normal part of any agricultural operation. It has a particularly importance in water-challenged areas where soil moisture is an issue. During the winter months in these areas, there is usually sufficient precipitation to maintain adequate water content levels in freshly planted trees. However, during the summer and early autumn, there is very little precipitation. This can adversely affect young trees. In this study, measurements were taken to determine root growth and variations in the upper parts of apple trees that were planted in the winter, compared to those planted in the spring when planting usually takes place. To do so, one-year-old 'Miyabi Fuji', grafted onto Marubakaido (Ma) (Malus prunifolia 'Ringo') and M.9 rootstocks, were examined from January through May. The results showed dramatic changes in root growth from March (average root length less than two cm before March) to May (average root length longer than 10 cm)for both rootstocks. Furthermore, trunk moisture content increased over time (51.8% in January and 56.1% in May on M.9). Although root growth in the young apple trees occurred, it is unknown if root water absorption began before or at the same time of the root growth. Root growth developed favorably because of the soil moisture generated by the winter precipitation. We found satisfactory root growth and tree moisture content changes in the trees used in the study, leading us to recommend winter planting in areas where water resources are limited in the non-winter months.
