Laparoscopic cholecystectomy has not been reported during pregnancy. This is the first reported case of a cholecystectomy by laparoscopic technique in the third trimester of pregnancy. The patient (and her baby) had a rapid, uneventful recovery identical to that of a nonpregnant patient.
This report summarizes our experience with nonsurgical ovum transfer at Harbor-UCLA Medical Center. In 29 attempts, 12 ova have been recovered and transferred. Two ongoing intrauterine recipient pregnancies have resulted from this preliminary research. There were two complications: one ectopic pregnancy in a recipient woman and one retained pregnancy in a donor woman who aborted spontaneously.

Noniodinated subunits of thyroglobulin can aggregate, but iodination of the aggregate is required for its stabilization (maturation). Rat-thyroid slices incorporate amino acids into subunits, but cannot form mature thyroglobulin from the newly synthesized subunits. This defect leads to an accumulation of 16S and 12S proteins, although the preexisting thyroglobulin is 19S. Accumulation of 16S and 12S proteins can be produced in rat thyroids by the administration to the animals of a thiocarbamide derivative, methimazole. Upon withdrawal of methimazole, iodination of the 16S and 12S proteins proceeds, and 19S protein appears.
