A 4-year evaluation of the chronic toxicity of megestrol acetate in dogs is reported. .01, .1 or .25 mg of megestrol acetate/kg/day or .25 mg of chlormadinone acetate/kg/day was administered orally for 4 years t o female beagle dogs. The hormone-treated dogs tended to gain more weig ht than did the controls (controls vs. .25 mg megestrol acetate every month after the 3rd p less than .01). All treated dogs revealed decreased evidence of estrus. Mucoid vaginal discharges were more prevalent among the middle and high dose groups. Mean hemoglobin, packed cell volume and total erythrocyte values were slightly decreased while mean total leucocyte count and erythrocyte sedimentation rates were slightly increased in the middle and high dose groups. Clotting me chanism did not reveal any disturbances. Evidence of diabetes consistin g of bilateral cataracts, elevated serum glucose concentrations and glycosuria after 4 years in 2 of 16 high-dose megestrol acetate and in 6 of 15 chlormadinone acetate-treated dogs was revealed. It is concluded that the effects of megestrol acetate were similar but less severe than those of chlormadinone acetate.

The regional density of perfused cerebral capillaries (rDPC) and regional cerebral blood flow (rCBF) were measured in 12 selected brain regions in rats after 3 and 20 weeks of streptozotocin-induced diabetes and in control groups. After 3 weeks of diabetes, both rCBF and rDPC were unchanged in the diabetic group compared to the control group. A diabetes duration of 20 weeks causing bilateral cataracts induced a significant (p less than 0.05) reduction in rCBF in two structures in the visual system compared to the control group (visual cortex: 105 versus 129 ml 100 g-1 min-1; lateral geniculate body: 106 versus 128 ml 100 g-1 min-1) and in the pontine reticular nucleus (82 versus 128 ml 100 g min-1), whereas rDPC remained unchanged. A highly significant correlation between rCBF and rDPC was found in both control groups (r = 0.8, p less than 0.005) whereas the correlation was more scattered in the diabetic groups (r = 0.6, p less than 0.05). The present results show that during chronic diabetes, a reduction of rCBF does not affect the number of perfused capillaries.

We describe a 35 year old woman with shortness of stature, skin and muscle atrophy of the face and lower limbs, peripheric arthropathies, feet deformity, plantar hiperqueratosis, alopecia, canities, bilateral cataracts and bitonal voice. At the age of 21, the patient started having plantar hiperqueratosis, deformity and stiffness of the feet joints. At the time of the examination the patient had neither diabetes mellitus, nor peripheric arteriopathies or neoplasms. There wasn't a family history and the parents weren't consanguinous.

A 41-year-old woman was diagnosed as having Werner's syndrome associated with bladder cancer. The patient noticed sudden, total gross hematuria in September, 1985. Cystoscopy revealed a papillary tumor with a stalk that was accompanied by a daughter tumor and concealed the left ureteral orifice. The tumors were 25 X 20 X 10 mm and 15 X 10 X 5 mm. Double contrast cystograms, computed tomography and transurethral echo showed no invasion of muscle layer. Intravesical instillation of mitomycin (10 mg), cylocide (300 mg) and adriacin (30 mg) was carried out 3 times per week for 4 weeks. Tumor size was reduced, and then TUR was performed. High power section of the removed bladder tumor showed pathologically PNT, TCC, grade II, INF alpha, pTla, lyo and v(-). The patient had such clinical manifestations as short stature with low body weight, thin limbs and stocky trunk, senile face, early graying hair, highpitched voice, bilateral cataracts, osteoporosis, sclerodermia-like signs, flat feet, tendency toward diabetes mellitus and parental consanguinity. Hyaluronic acid was not detected in the urine. To the best of our knowledge, this seems to be the 30th report describing the association of malignancy with Werner's syndrome in Japan; besides, only one other case of bladder cancer in Werner's syndrome has been reported to date in the world.

A 21-yr-old Caucasian man developed accelerated irreversible dense bilateral cataracts 4 wk after control of his newly diagnosed insulin-dependent diabetes mellitus (IDDM) and 12 wk after the onset of his symptoms. Although transitory cataracts have been identified in patients with newly diagnosed IDDM, there is no mention in the literature of irreversible cataract formation this soon after diagnosis (see ref. 1).

Of 85 Indian patients with non-insulin-dependent diabetes in the young, 16 (19%) were found to have vascular disease. Of these 16 patients 14 had diabetic retinopathy and 6 nephropathy. Five of the patients with nephropathy also had retinopathy, and the 6th had bilateral cataracts. Three patients had ischaemic heart disease associated with nephropathy and/or retinopathy. No patient had peripheral or cerebrovascular disease, and 15 (18%) were found to have hypertension; 5 (31%) of the patients with vascular disease had hypertension.

Increased hemoglobin A1 (HbA1) occurs in diabetes mellitus as a direct consequence of hyperglycemia, which causes postsynthetic modification of hemoglobin proportional to blood glucose concentration. Glycosylation of hemoglobin is demonstrable also in vitro, not only by glucose, but with other reducing sugars such as galactose. The purpose of this study was to show that increased HbA1 could be induced by feeding rats a diet enriched either by galactose or sucrose. A third experimental group consisted of rats made diabetic by injection of streptozotocin. Exposure to a diet of 40% galactose resulted in a diabetes-like state with polyuria, weight loss, muscle atrophy, fat depletion, bilateral cataracts, peripheral neuropathy and significantly elevated HbA1. Blood glucose levels were not elevated and after four months of galactose feeding there was hypoglycemia. Total HbA1 was determined by a microcolumn chromatographic procedure, recently made available for clinical use. Increased HbA1 was also found in rats which received a diet of 68% sucrose for several months. The highest values of HbA1 were determined in streptozotocin diabetic rats and there was significant correlation with plasma glucose concentration. Development of experimental models for increased HbA1 by dietary exposure makes it possible to relate increases in HbA1 to measured amounts of sugar included in the diet. Increased HbA1 in galactosemic and diabetic rats provides a biochemical marker which may be correlated with the evolving morphologic changes such as basement membrane thickening occurring in certain tissues in diabetes mellitus.

Sorbitol dehydrogenase (SORD) was quantitatively assayed in a family in which four out of five brothers and their father had bilateral cataracts. Three sibs (two of them with cataracts) and both their father and paternal grandfather had SORD activity of about 25% of the reference values; of the other two affected sibs one had about 50% and the other had 75%; the mother and two paternal uncles had about 75%. These results do not define a clear cataract-SORD deficiency etiopathogenic relationship, nevertheless, they strongly suggest activity polymorphism in human red cell SORD, which would be highly relevant not only to the study of cataracts but of other major complications in diabetes.

Since 1984, five patients in the cystic fibrosis (CF) clinic at Cork Regional Hospital have developed diabetes mellitus (DM) and were treated with Insulin. None had received systemic corticosteroids but two had high calorie naso-gastric feeding regimes. Two died from lung disease. A fifteen year old boy developed bilateral cataracts. In nine other paediatric CF clinics in the Republic of Ireland (total: 420 patients), three patients have DM, two receiving Insulin. Abnormal glucose tolerance is becoming more common in CF as patients survive longer. The possible role of corticosteroid treatment and intensive carbohydrate feeding regimes in development of glucose intolerance must be considered. DM in CF differs from the usual childhood DM. Regular screening and early Insulin supplementation may be beneficial.

The reference ranges of the trace elements Al, As, Be, B, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Li, Rb, Se, Sr, and Zn were determined by inductively coupled plasma-mass spectrometry (ICP-MS) in sera of a group of free-ranging plains viscachas of the pampa grasslands of Argentina. The values were compared with those of a small group of captive plains viscachas of the Zurich Zoo with diabetes and bilateral cataracts. In addition, a method for digestion of whole-blood samples is described for the trace element determination. Significant differences in the concentration of trace elements in the two groups of animals are discussed. No correlation was found between the levels of selenium and of other trace elements compared to the formation of cataracts.
