We report a case of polypoid endometriosis and correlate the MRI findings with the pathological findings. The polypoid endometriosis appeared as multiple polypoid masses protruding into the adjacent pelvic organs, including the uterus and rectum. The masses were found to show hyperintensity on T(2) weighted images, which was similar to the signal intensity of the uterine endometrium, reflecting the presence of abundant endometrial-type glands. The masses were also surrounded by hypointense rim-like structures on T(2) weighted images. These structures were confirmed by pathology to correspond with fibrous tissues arising from endometriosis. These features, together with an intense enhancement similar to the adjacent uterus, may be a diagnostic clue to this rare entity.

Ectopic gastric mucosa in the upper esophagus is easily demonstrated at routine examination of the upper GI tract. Diagnosis can be based on location and characteristic radiographic appearance.

An 8-channel Grass Model III electroencephalograph was employed for EEG recording and to provide pre-amplification of signals processed by 2 computers of average transients (CAT). The frequency response of the system, selected for optimal rejection of myogenic potentials, was such that output amplitude was down 40 % and 80% at 50 c/sec and 100 c/sec respectively (see Kooi and Bagchi 1964a).

Bovine heart 67-kd protein (p67) was coisolated with calpactin I complex by cycles of Ca2'-dependent precipitation followed by solubilization with EGTA-containing buffer. Using affinity-purified anti-p67 antibody and anti-p36 (36-kd subunit of calpactin 1) antibody, we examined the localization of the two proteins in secretory atrial myocytes and other endocrine tissues of adult rats. Immunofluorescence microscopy showed that p67 was expressed both in the atrial myocytes in situ and in cultured atrial myocytes in which we failed to detect p36 and that p67 appeared to be closely associated with the cell surface. We also found that p67 was colocalized with p36 in the thyroid follicle epithelium and zona reticularis of the adrenal gland. tor proteins or Ca2'-regulated phospholipid-binding proteins has been identified. Of these proteins, which have been given the generic name annexin,6 calpactin I seems to be a leading candidate for a crucial Ca2'receptor that might promote contact between secretory vesicles and the plasma membrane.7In the present study, calpactin I and a coisolated 67-kd protein (p67) were obtained from bovine lung or heart by cycles of Ca'+-dependent precipitation followed by EGTA resolubilization. Using affinity-purified antibodies to p67 and the 36-kd subunit of calpactin I (p36), we examined the distribution of both antigens in atrial myocytes and other endocrine tissues of adult rats by immunocytochemical techniques. The results showed that both atrial myocytes in situ and cultured atrial myocytes expressed a significant amount of p67 but did not contain a detectable amount of p36. The p67 antigen in the atrial myocytes was found to be closely associated with the sarcolemma of the cells. Although neither p36 nor p67 was a ubiquitous protein in rat endocrine cells, p67 was colocalized with p36 in some types of cells of endocrine tissues that were examined. Amino acid composition, Ca2+-binding property, and molecular shape of the bovine heart p67 were also shown in the present study.
