Benign and malignant struma ovarii.

Three cases of struma ovarii are reported, two of which were benign, and one which was malignant. Immunoperoxidase studies confirmed that the tumors secreted triiodothyronine and thyroxine, but no carcinoembryonic antigen nor alpha-fetoprotein. In the case of the malignant struma ovarii, the patient's thyroid was histologically normal, and thus the possibility of a metastasis to the ovary from a primary thyroid carcinoma was excluded.

Anatomy of the retina of the mink (Mustela vison).

The retina of the normal pigmented mink has been studied by light and electron microscopy. This retina resembles the typical vertebrate retinia in its patterns of lamination and synaptic interconnectivity. Rod and cone outer segments and receptor spherule and pedicle endings are found. At least two different types of horizontal cell processes are seen with the electron microscope, suggestive of rabbit A and B types. Ribbon and conventional synapses are found in both plexiform layers; conventional synapses are also present in the inner nuclear layer. Quantitative studies of the inner plexiform layer revealed amacrine:bipolar synapse ratios (3.3:1) similar to those of the cat and monkey. Other quantitative parameters also resembled those previously reported for species with retinas that predominantly contain concentric-type receptive fields.

Stress management for patients with heart disease: a pilot study.

OBJECTIVE: To conduct a feasibility study on stress management for patients with heart disease; more specifically, to test the availability of patients, determine dropout rates, and investigate the sensitivity to change of a large number of psychologic and biologic stress indexes. DESIGN: Random assignment, two-group clinical trial. SETTING: Pacific Northwest university-affiliated teaching hospital. PATIENTS: Forty-five patients with heart disease (mean age 56 years), who either had a myocardial infarction or coronary bypass surgery. OUTCOME MEASURES: Hostility, subjective distress, resting electrocardiogram, resting blood pressure and blood pressure reactivity to a psychologic stressor, and blood lipid, cortisol, and catecholamine levels. INTERVENTION: Patients were randomly assigned to either (1) exercise rehabilitation (ER) and an 8-week stress management (SM) program (ER + SM) or (2) ER only. Although the recruitment rate was satisfactory, 67% of patients assigned to the control condition and 40% of the SM subjects were not available for posttesting. RESULTS: Computed effect sizes indicated that blood pressure reactivity to a psychologic challenge was reduced after treatment in the ER + SM group but not in ER group. The ER + SM group showed improvement in perceived health status and had clinically meaningful reductions in triglyceride levels, whereas the ER group did not. The ER group had a reduction in high-density lipoproteins, whereas the high-density lipoprotein levels of the ER + SM group did not change. CONCLUSIONS: Patients randomly assigned to a control condition may be less willing to participate in time-consuming and invasive posttests than treated patients. Reducing the invasiveness of measurement may increase cost-effectiveness and reduce the dropout rate under controlled conditions. Blood pressure reactivity to a psychologic stress test and changes in serum lipid levels may be sensitive and cost-effective measures to include in future studies of cardiac rehabilitation.
