Psychiatric examination has been made in all eight adult males with the karyotype 46,XX diagnosed in Denmark til 1976. Apart from emotional immaturity in most probands, no psychopathological traits were found, except in one who had neurotic symptoms. They were all of normal intelligence and socially well adjusted. All had male psychosexual orientation, but weak sexual libido and potency were found in the oldest probands. In several respects males with 46,XX differ from Klinefelter males with the karyotype 47,XXY, and the reasons for this are discussed.

Five coronal levels of the arcuate nuclei in newborn male and female rats were examined with the transmission electron microscope. The nuclei from male and female neonates appear similar in all respects. All levels exhibit a significant population of round to oval cell profiles with large centrally located nuclei and scant cytoplasm which contains predominantly ribosomes, sparse mitochondria, and a few short cisternae of rough endoplasmic reticulum. These organelle-poor cell profiles resemble neuroblasts in other parts of the developing CNS. The arcuate nuclei of neonates also exhibit some cell profiles with the variety and quantity of organelles characteristic of mature neurons in the arcuate nuclei of adult rats. In addition, the neonatal arcuate nuclei show a paucity of synapses with apparent immaturity of those present, and numerous structures identified as growth cones. Definitive macroglia are not present in the arcuate nuclei of newborn rats.

We report 22 cases of hepatic necrosis following catheterization of the umbilical vein. The morphology of the necrotic lesions, which were confined to the left lobe in 21 patients, was that of an anemic infarct. Their causes are multiple and include intimal damage during the insertion of the catheter with consecutive thrombosis of portal vein branches, the postpartum immaturity of the arterial hepatic oxygen supply, postpartum hypoxia due to respiratory failure of cerebral or pulmonary origin, obstruction of portal venous flow through the catheter as such, the postpartum involution of the left hepatic lobe, and prolonged periods of catheterization. Toxic damage of the hepatic parenchyma due to an infusion of Tris buffer through the catheter into the portal venous system is a potential additional factor.

Comparison of cytohormonal patterns in full-term and pre-term babies of both sexes showed significant differences. At birth, irrespective of gestational age, both groups had high oestrogen levels, reflecting the maternal hormonal environment, but whereas the mature neonates were capable of metabolising and excreting the excess hormone within the first week of life, the pre-term infants took much longer to do so. It is thought that immaturity or impairment of liver function is at least partially responsible for this finding.

A previously described method for the determination of phospholipid concentration in amniotic fluid without digestion has been modified to make it more suitable for use in a routine laboratory. Results compare well with those by the original procedure. Results from nearly 70 amniotic fluids, collected at delivery, were compared with lecithin/sphingomyelin (L/S) ratios determined on the same fluids. Statistical analysis of these data showed that for the prediction of lung immaturity, determination of total phospholipid concentration was at least as good as the L/S ratio.

Although numerous references are made to the stressful, deleterious effects of chronic or terminal illnesses and handicaps on the siblings of pediatric patients, very few studies have been conducted using comparison groups. The present study compared the adjustment of 3- to 13-year-old siblings of pediatric hematology (N = 62), cardiology (N = 57), and plastic surgery patients (N = 37) with healthy siblings (N = 46). The adjustment measure was an objective, paper-and-pencil measure of children's emotional and behavioral problems, the Louisville Behavior Checklist. On analyses of covariance, the patient groups were more likely to show symptoms of irritability and social withdrawal, and the differences between illness groups approached significance on measures of fear and inhibition. Among the younger children, ages 3 to 6, there were significant group differences, with the siblings of patients undergoing plastic surgery showing the highest level of general psychopathology. Among children ages 7 to 13, male siblings of patients with blood disorders were more likely to show signs of emotional disturbance than female siblings. No group differences were noted on measures of aggression or learning problems. Significant interactions between sex and age relationship to the child were noted on scales of social withdrawal, inhibition, immaturity, and irritability.

The physiological protien and glycoprotein excretions in the urine samples of a larger group of newborn infants were separated according to the molecular weights by SDS polyacrylamide gel electrophoresis and compared with the protein excretions of older children. We found higher proportions of albumin, of high molecular weight (MW = molecular weight greater than or equal to 150 000 dt) and of lower molecular weight (MW less than albumin 6800 dt) proteins in the first 24-h urine samples after birth. One week after birth the low molecular weight proteins predominated because there was a substantial decrease in the excretion of albumin and of high molecular weight proteins (MW greater than or equal to 150 000 dt). We compared the patterns of protein excretion of the newborn infants with those of children aged from 2 1/2 to 15 years. These urines samples showed a typical pattern of protein excretion not correlated to the age. These findings express a transitory immaturity of the glomerular filter and of the tubular protein reabsorbing system of the newborn kidney. Apparently, the tubular protein handling normalizes later than the glomerular filtration of proteins.

Cytoplasm of Paramecium caudatum syngen 3 in the period of sexual immaturity was effective in inducing immaturity when injected into mating-reactive cells of other syngens of P. caudatum. When immature cytoplasm of P. caudatum was injected into mature cells of P. multimicronucleatum, immaturity was also induced in the latter cells. When cytoplasm of P. bursaria in the immaturity period was injected into mature cells of the same species, the latter became immature. But immature cytoplasm of P. caudatum was ineffective when injected into mature cells of P. bursaria. When immature cytoplasm of P. busaria was injected into mature cells of P. caudatum, no difference from the control was observed. These results suggest that a difference in specificity of the immaturity substances exists bewteen paramecia of the 'aurelia' group and those of the 'bursaria' group.

1. Female guinea pigs made tolerant before pregnancy do not transfer tolerance to their offspring. This result favours the concept of cellular mechanism of tolerance. 2. Guinea pig fetuses become tolerant when exposed to the tolerogen in the last two weeks of pregnancy. This is due to active tolerization by the tolerogen passing the placental barrier. 3. Fetuses exposed to the antigen earlier did not develop tolerance. This is due to immunological immaturity rather than to insufficiently developed vascularization. No functional active depot of tolerogen is formed. 4. Guinea pigs become immunologically mature between the 54th and 61st day of fetal live.

After investigating as much literature as I could on the Oedipus Complex or whatever name is interspersed, such as sex-role differentiation, identification, etc. the following conclusions were significant. Possible disturbance in sex-role identification, child develops avoidance systems and rejects parents, homosexuality, emotional maladjustment, shyness, resentfulness, dependency, harder to train, not "manly enough", apprehension, immaturity, compensatory masculinity, anti-social behaviour such as truancy, damaging or destroying private or public property, having premarital and extra matital sex relations and theft of property. Father's presence then, is of the utmost importance in the rearing of their children, particularly sons. They are necessary in the sharing with mothers of all phases of child.
