I-123-omega-heptadecanoic acid (HDA) was evaluated for myocardial scanning in 59 healthy volunteers and 133 patients, using a 7-pinhole collimator. Early (uptake) and late (retention) images were compared visually. Regional HDA elimination was also followed semiquantitatively based on the calculation of a retention-over-uptake ratio, R(phi), derived from(More)
1. In a previous study in rats, an increased PAH clearance was found following chronic phenobarbitone administration. These results formed the basis for the present study in which fifteen healthy male volunteers were investigated and the parameters of liver microsomal enzyme activity and renal function were measured. 2. As parameters of liver microsomal(More)
During 1977, 246 hyperthyroid patients were seen in our departments, 140 (57%) with nonimmunogenic hyperthyroidism (NIH)--101 with a toxic adenoma (TA) and 39 with multifocal functional autonomy (MFA). All patients but one could be followed over 9 yr, 101 after 131I treatment (RIT), another 29 after surgery (S). Ten patients were left untreated. Thirty-four(More)
We report a case of a man presenting with a cervical malignant teratoma and a chondrosarcomatous rib metastasis. He was alive and free of recurrence five years and 10 months (= 70 months) after resection of the primary mass, followed by chemotherapy and subsequent resection of the rib tumor. This is the 35th patient reported in the literature and the first(More)
Four patients with Parkinson's disease (PD) achieved excellent improvement of their unilateral tremor by chronic deep brain stimulation (DBS) of the contralateral ventral intermediate (Vim) nucleus of the thalamus. Repeated measurements of cerebral blood flow were obtained 14 days apart off and on stimulation using 99mTc-ECD SPECT. Subjects were scanned at(More)
SUMMARY On the basis of a comparison of the shunt diagnoses in 73 radiocardioangiographic examinations with those from cardiac catheterization supplemented by operation and/or autopsy findings, it is shown that an intravenous injection of 99mtechnetium pertechnetate with subsequent evaluation using a scintillation camera and computerized regional(More)
We examined acute effects of intravenous diacetylmorphine (heroin) administration - which induces a characteristic biphasic response: A short rush-sensation associated with intense pleasurable feelings followed by a subjectively different period of euphoria on cerebral blood flow. This was assessed in nine male heroin dependent patients participating in a(More)
Hyperthyroidism was diagnosed in 53 of 273 thyroid carcinoma patients at the time of their first examination (between 1971 and 1983). This corresponds to 19.5% of these mainly well-differentiated thyroid cancers. In 24 (45%) patients the hyperthyroidism and the thyroid carcinoma were two separate distinct illnesses: of 4 patients with Graves' disease (1.5%(More)
BACKGROUND In previous studies, tropisetron has been shown to accelerate gastric emptying of a solid meal. However, it is uncertain whether other specific 5-hydroxytryptamine-3 receptor antagonists, such as ondansetron, also have a gastroprokinetic effect in humans. AIM To evaluate the effect of ondansetron on gastric half-emptying time (T1/2) of a solid(More)
