144 placentas were sampled from all cases of stillbirth weighing 500 g and above seen over a period of thirteen months in the UKM Unit of the Maternity Hospital, Kuala Lumpur. Sampling was limited to 1-3 blocks per placenta for histological study. Placental abnormalities were found in 121 (85%) placentas, 78 of which had definite lesions known to contribute to foetal death while the remainder s...

Kurt Benirschke studied cells, placentas, and endangered species in Germany and the US during the twentieth century. Benirschke was professor at the University of California in San Diego, California, and a director of the research department at the San Diego Zoo in San Diego, California. He also helped form the research department of the San Diego Zoo and its sister organization [3], the Center...

The fetal risk in maternal diabetes mellitus is high [5, 6]. The reasons for fetal macrosomatia are controversially as are those for intrauterine fetal growth retardation and intrauterine fetal death. These mostly happen without prodromes and are feared by all obstetricians. Morphologists have described signs of a so-called chronic placental insufficiency in cases of small for date infants and ...

Placentas from 191 consecutive deliveries were cultured for Neisseria gonorrhoeae and other bacteria before being examined histologically. N gonorrhoeae was seen on direct microscopical examination and cultured from two placentas, one of which had chorioamnionitis and the other had a granulocytic invasion of the membranes. In both patients, rupture of the membranes had occurred two hours or les...

Particles with the morphology of type C virus have been identified from primate placentas by electron microscopy. A reverse transcriptase (RNA-dependent DNA polymerase) was isolated and purified from microsomal pellets of two fresh placentas of rhesus monkeys in the early stages of gestation. This enzyme was biochemically similar yet immunologically distinct from the reverse transcriptases of k...
