[The placenta in herpes].

Forty placentas from patients affected with herpes simplex viruses of type I and II were studied by means of light and immunofluorescent microscopy, morphometry and serological investigation of fetal (infant) and mother's blood. Various morphological alterations in placenta were established. Some of them were specific and resulted from the effect of herpes virus on the cells (amniocytes, syncytiotrophoblast, decidual cells, vascular endothelium). The affected cells increased in size, herpes antigen was detected in their hyperchronic nuclei. Apart from this, in all placentas as well as in their vessels, moderate inflammatory response was observed. When antenatal death occurred, poor vascularization of villi was observed and specific alterations were most pronounced. When death occurred antenatally, alterations produced by herpes were rather moderate and acute alterations of placenta circulation predominated. In children born in a good condition, both specific and nonspecific alterations were insignificant and villi vascularization was good.

[Pathological anatomy of a herpes infection caused by herpes simplex type 2 virus in infants].

Materials of autopsies of 52 children suffering from severe herpetic infection, intrauterine as a rule, were analysed. The etiology of the process was proved by immunofluorescent and serological examinations. The disease was markedly generalized, however, with predominant involvement of the liver, lungs, and central nervous system of the type of pneumonia, hepatitis and encephalomyelitis. Early in the disease, changes of alveolocytes, hepatocytes, and other epitheliocytes were observed, consisting primarily in a peculiar alteration of their nuclei. Simultaneously, moderate signs of inflammation were observed, but in most severe cases it was alterative.

[A method for diagnosing allergy by studying eosinophil morphology].

A total of 107 children with various clinical manifestations of food allergy were examined to investigate the morphological changes of eosinophils under the effect of food allergens. Eosinophil "injury" caused by cow milk allergen was detected in 71.4%, that caused by hen egg white in 82.4%, and that under the effect of fish in 77.8% of the examinees, these data being useful as a laboratory test for the diagnosis of food sensitization. Correlation between the index of eosinophil injury and late reactions to cow milk, as well as increased reactivity to nonspecific stimuli were traced.
