Miscellaneous Hartman, Carl 0.: Regeneration of the Monkey Uterus After Surgical Removal of the Endometrium and Accidental Endometriosis, West. $1. Snrg. 52: 87, 1944. At the Carnegie Institute, the technique for the recovery of early ova in the monkey consisted of enucleation of the cnt,irr endometrium as an intact SW. Following laparotomy, the uterus was incised longitudinally down to the endomrtrium and the endometriunl was then dissectctl out with ~alpel and scissors. In some experiments the exposrtl myometrium wnz then wiped clean with a cotton sponge so that no vestige of the muPosa was visible to the naked eye. These operations were followed by studies of the regenerated c~ndnmetrium, and it was discovered that complete regeneration often oc(‘urs as hoon as the ristecnth postoperative day. In some monkeys, castrxt,ion was perfnrrtle
the regener:ltion rapid latcl.

In the prnvess of removing the entlomeirium, it, is inevitable that hi Iti IJf tissue Endomctriosis and formation of chocolate are droppet into the peritoneal cavity. cysts were common. However, this does not prove or dipprovo the Sampson theory (1) The necrotic, desquamatnl tissue of menstruation is less likely for 2 reasons: to transplant than the normal endometriurn which was rpille~l in these experiments. In the experiments of Markee, it wah found quite M&ult to transplant menstruating endometrium to the anterior chamber of tlax eyr while the other transplanteil easily. (2) The uterotubal junction is of such a clmracter as to make it difficult to force any liquid from t,lie uterus to the tubes, especially during menstruation. ~~IILIAiil
