[The decrease in thyroid hormones in CAPD is not explained either by iodine saturation or by dialysate loss].

Total T4, total T3 and TSH were measured in blood, urine and dialysate of 13 patients on CAPD. Iodine was measured in blood and urine. Free T4 and T3 were measured in blood only. Serum measurements revealed one true hypothyroidism, normal total T4, T3 and TSH for 12 patients, low free T4 and T3 with normal TSH for 9 patients. Iodine was slightly elevated for 3 patients. Urinary T4 and T3 were low. Dialysate T4 and T3 were low (T4 = 13, 6 nmol/24 H). Low free thyroid hormones are not relevant to iodine excess, nor to dialysate losses. Low free thyroid hormones may be considered as an endocrine dysfunction of chronic illnesses.

Prolonged refractoriness to the diabetogenic action of streptozotocin in mice.

A single intraperitoneal injection of 5 mg (250 mg/kg body wt) streptozotocin induced overt diabetes within 48 hr in male, 6-week-old mice of C57BL/6 and C57BL/10 (sensitive) strains. The C3H/HeJ and C3H/eb (resistant) strains exhibited a progressive delayed-onset hyperglycemia which required 6 weeks to reach the level seen within only 48 hr in sensitive strains. Resistance to SZ-induced diabetes was not related to changes in body weights or different pharmacokinetics of the drug. C3H/HeJ (resistant) mice showed a smaller fall in immunoreactive insulin pancreatic content and less severe damage of pancreatic islets on histologic examination, when compared to C57BL/6 (sensitive) mice during the first week post-SZ. These results suggest that strain-related resistance to SZ-induced diabetes may be mediated at the level of the beta cell's responsiveness to the cytotoxic action of the drug. This very simple experimental tool may be of value in monitoring the period before the onset of overt insulin-deficient diabetes and for probing the nature of factors that constitute a genetically resistant pancreas, understanding of which could aid management of diabetes mellitus in humans.

Localized deep microwave hyperthermia in the treatment of poor operative risk patients with benign prostatic hyperplasia.

Non-invasive localized deep microwave hyperthermia was applied as an alternative treatment to surgery in 29 patients with contraindications for prostatectomy. Patients were treated twice weekly, on Mondays and Thursdays, for 1 hour, without sedation on an outpatient basis. All patients tolerated treatment well without secondary effects. The results indicate that localized deep microwave hyperthermia applied by this method is safe and effective in the treatment of benign prostatic hyperplasia.
