Depression in children has an unfavourable influence on the psychosocial development of the individual, therefore it requires suitable therapeutic and prophylactic approach. The dependencies between school-age immaturity and the prevalence of depression in children were evaluated in the prospective study. The school maturity, and one year later the prevalence of depression were studied in a representative sample of 502 "0"-grade children from the large urban population. The school immaturity was found in 10.56% of probands. More common symptoms were: withdrawal and antisocial behaviour. Depression was found in 32.79% of first-grade students, more frequent children with adaptation difficulties, especially among school-immature boys. The premature biological development, the symptoms of organic brain damage, and low I.Q. do not explain sufficiently neither the school-immaturity nor the prevalence of depression in children. It was found that emotional and social immaturity to the school duties facilitates the onset of depression among I grade students, while the role of the family and school in the genesis of both phenomena studied requires further investigations.

In a group of 23 patients with chronic lymphocytic leukaemia in 1-4 clinical stages of the disease according to Rai et al (34) classification, mostly untreated (only 5 treated) considerable heterogeneity was found as evidenced by: variability of the morphological patterns of bone marrow, differences of immunological phenotypes of peripheral blood lymphocytes between individual cases, --coexistence of the features of maturity and immaturity in the populations of peripheral blood lymphocytes in the same case.

Examinations were made with the use of same materials as in Part I and according to the same methodology. The great capability of the calves kidneys to economise water was observed. The kidneys are able already in the second week of calves life to reduce and increase urine concentration within limits from 65.70 to 955.54 mmol/kg H2O, keeping at the same time molality of the body fluids on relatively the same level. It may prove high efficiency of the hypothalamic pituitary antidiuretic system. It seems, that because of the probable immaturity of tubules it was difficult to create the high osmotic gradient in the renal medulla what is confirmed by the changing clearances of the free water and the resorption water. It also seems, that the rate with which urine is passing through the renal tubules is of great importance in the process of thickening the urine in this period.

Clearance experiments concerning the influence of hypophysin + (0.1 vol. unit/kg) and desoxycorticosterone-21-acetate (0.1 mg/kg) on sodium, potassium, calcium, magnesium and inorganic phosphorus excretion in urine have been carried out on 12 bulls at the age of 2-5 weeks of life. After hypophysin injection kidney purification of sodium, potassium and chloride ions has been noticed and hypophysin effect on tubular absorption processes turned out to be clearly late in relation to its influence on glomerular filtration decrease. After desoxycorticosterone-21-acetate injection, lowering of clearances of both sodium and potassium has been noticed and it may prove that kidney mechanisms responsible for potassium ion regulation show functional immaturity. Hypophysin and desoxycorticosterone-21-acetate in calves at the age 2-5 weeks have not affected kidney processes of calcium, magnesium and inorganic phosphorus excretion in urine.

EEG tracings were analysed in 100 children of 58 fathers with epilepsy. A group of children aged up to 18 years was isolated and in 40 of them serial EEG investigations were carried out during 4-5 years. In this group abnormal tracings were found in 51% of cases, with seizure activity in 31%. In five children (5%) epilepsy was diagnosed. Seizure activity was significantly more frequent in girls than in boys (42.8% vs 19.6%). Seizure activity occurred with similar frequency in children born before or after manifestation of the disease in the father (30.1% and 31.9%). The observation of evolution of seizure activity during 4-5 years suggests that the greatest penetration is at the age of 4-7 years (52.6%) and then it decreases gradually. Non-seizure pathological activity with features of bioelectric immaturity was observed most frequently in the youngest children aged 1-3 years, especially in boys. The evolution of these changes was bidirectional: in most cases the tracings became normal within 4-5 years, in a lower number of cases seizure activity appeared.

In a 7-year prospective follow-up of 104 children with enuresis in 32 cases (19 boys and 13 girls) coexistence of common migraine was found. Twenty-two children had various other seizure-like disorders, particularly tics, febrile convulsions, pavor nocturnus and fainting, and three had absence attacks. In 20 cases vasomotor disturbances and in 17 abnormal Schellong's test were found. The IQ was normal or high in all cases. Emotional disorders were observed in nearly half the cases. The water-salt test of Decourt was done in 9 cases and it was abnormal in 8 cases. At least two abnormal EEG records were obtained in 26 cases, and in 24 of them seizure activity was demonstrated in the EEG. In the period of follow-up disappearance or very marked improvement of enuresis occurred in all cases and migrainous attacks became less frequent and intense in 27 cases, while in 5 the severity of migraine increased. The author discusses the pathological mechanism of these disturbances calling attention to less good efficiency of the regulatory functions of the centrencephalic activating system and hypothalamus connected with biochemical and bioelectric immaturity.

EEG curves were evaluated in 40 children with spinal muscular atrophy. The compared group comprised 81 boys with Duchenne's dystrophy in the same age group. In the children with muscular spinal atrophy the EEG was considered abnormal for age in 42% of cases. The type of EEG changes might suggest bioelectric immaturity. In Duchenne's dystrophy the proportion of children with abnormal EEG records was 70%, and the changes were mostly focal.

The feces of 52 children without diarrhea, aged from 5 days to 22 months, treated in the Department for various causes was investigated for the presence of that might be the cause of infectious diarrhea. Samples were taken at the beginning and the end of hospitalization. The results were analyzed with reference to 5 age subgroups (1 month, 2-3 months, 4-6 months, 7-12 months, 12-22 months) and duration of hospitalization (3-42 days). The presence of potentially pathogenic bacteria in the feces was found in 87% of children without diarrhea, especially at the beginning of hospitalization, which suggests the possible existence of a "transient carrier state". Because of the immaturity of a number of intra-organism mechanisms, the presence of pathogenic bacteria in the alimentary tract in the youngest children, may be a potential danger of developing serious, even generalized disease processes and may constitute an important source of nosocomial infections.

Neuropathological examination of six brains of newborns and infants who died in the course of congenital cyanotic cardiac anomalies showed focal brain lesions. The material included five cases from two weeks to two months of age, and one two-year-old infant. In two of them, the periventricular ischemic infarcts were found, in one multifocal encephalomalacia due to multiple vascular occlusions, and in three the necrotic foci corresponded to the supply of large cerebral arteries. The character and topography of severe brain lesions, particularly within the hemispheric white matter, were clearly influenced by the immaturity of the cerebral structures.

A group of 91 neonates born in different states of the perinatal risk was analysed. During the ultrasonography testing of the brain the intracranial bleeding was stated. The dominant risk factors of the occurring of bleeding were EPH gestosis, preterm rupture of the membranes, operative delivery and the immaturity of the immaturity of the child.
