[Evaluation of endobronchial foreign bodies by 99mTc-MAA pulmonary perfusion scintigraphy].

We evaluated the lung perfusion scintigraphic findings of endobronchial foreign bodies in four children. We could detect the bronchial stenosis due to foreign bodies by lung perfusion scintigraphy more easily than plain chest radiograph and predict the location at lobar bronchi level according to the hypoperfusion area. We guessed that the scintigraphic abnormal finding after plain chest radiographic normalization reflect bronchial inflammatory change after foreign body removal and so it is very important to perform the follow up scintigraphic examination.

Serum alpha fetoprotein in gynaecologic related malignancies.

Serum alpha-fetoprotein (AFP) was examined by radioimmunoassay in 125 Japanese with various gynecological malignancies. Elevated serum AFP levels were frequently noted in patients with yolk sac tumor and solid teratoma, while normal AFP levels (less than or equal to 20 ng/ml) were seen in those with vulvar carcinoma, cervical carcinoma, endometrial carcinoma or ovarian carcinoma. Serum AFP levels were also within normal range in patients with uterine choriocarcinoma or ovarian dysgerminoma. The present findings indicate that serum AFP is an effective marker substance for the diagnosis of both yolk sac tumor and solid teratoma.

Study on the partial differential REM deprivation (PDRD).

With an aim to make observations on the rebound elevation of REM sleep, we have devised the partial differential REM deprivation (PDRD) method whereby the subjects are awakened forciby at a fixed time early in the morning. By this method, REM sleep is deprivated by about a half and stage 2 sleep by about one third of the baseline value; but stage SWS is not deprivated. When the test set of PDRD is performed repeatedly on an identical subject, the REM sleep time during PDRD night and recovery night is almost always constant. Our PDRD, we believe, is an excellent method that relieves the disconfort of the subject and the physical burden of research workers and yet is capable of measuring almost accurately the magnitude of rebound elevation of REM sleep in each subject.
