Spontaneously hypertriacylglycerolemic obese and diabetic inbred IIM Beta rats were treated with oleoylestrone for 10 days. Pair-feeding was performed to determine some oleoyl-estrone effects dependent on the caloric restriction it promotes. Twenty-five 200 day-old Beta males receiving a daily gavage of 0.2 ml sunflower oil were divided into the following groups: 1) daily dose of 10 nmol/g oleoyl-estrone; 2) pair-fed; 3) control. The variables measured were: whole body protein, water and lipid; retroperitoneal and epididymal fat depot weights; plasma urea, glucose, insulin, triacylglycerols and cholesterol. Biomass and food intake were assessed daily. Oleoyl-estrone and pair-fed groups expressed similar variations in body composition and significant body weight losses due to reduction in food intake. Oleoyl-estrone and pair-fed treatments significantly reduced retroperitoneal fat depot weights, but not epididymal ones. In oleoyl-estrone and pair-fed groups hyperglycemia decreased and insulinemia lowered significantly. Plasma normal total cholesterolemia and hypertriacylglycerolemia values typical of Beta rats decreased strongly compared to controls, though attaining significantly different values between oleoyl-estrone and pair-fed groups. Plasma total cholesterol appeared as more sensitive to caloric restriction than triacylglycerols through a specific oleoyl-estrone-mediated effect.

The eSMT rat is derived from the crossing of eSS and beta, both lines belonging to the IIM strain, while eSS is a model of type 2 diabetes without overweight and beta develops moderate obesity and late glucose intolerance. Metabolic characteristics and histopathological findings in endocrine pancreas of eSS and eSMT were compared. Young eSMT animals are more robust than eSS and develop more intense fasting hyperglycemia and glucose intolerance at an earlier age. eSMT males of 6 and 9 months show islets with altered shapes and fibrosis, as well as sporadic images of apoptosis. At 12 months of age, islets are reduced in number and size, resembling the histoarchitecture of eSS males during their second year of life; eventually islets undergo disruption and, at the same time, occasional mitoses and nesidioblastosis are seen. These dynamic modifications may be expressing a response to hyperglycemia. eSS females preserve their insular structure for a longer time and have less glycemic alterations. Sexual dimorphism of the diabetic syndrome of eSMT is attenuated when compared with eSS. The construction of a typology of individuals through multivariate analysis separated three clusters, evidencing genetic, age and sex differences.

A 1.5 year old neutered male pet ferret (Mustela putorius furo) was presented with a sudden onset of severe weakness. The ferret was kept with three healthy mates, was vaccinated against distemper regularly and was never ill before presentation. Clinically, the ferret was depressed, had a hyperthermia of 40.3 degrees C, tachypnea and ocular as well as nasal discharge. Blood work revealed a mild neutropenia, blood chemistry a hyperglycemia, hyperbilirubinemia, hypoproteinemia, hypoalbuminemia, hypocalcemia and hyponatremia. Despite intensive therapy including fluid replacement, antibiosis, analgesia and antipyretics, the overall condition of the ferret deteriorated and the animal was euthanized two days later. Necropsy revealed a pyogranulomatous myositis, fasciitis and steatitis of the long hyoid muscles, the esophagus and intestine. Lesions were consistent with the disseminated idiopathic myositis of ferrets. This is the first reported case of this disease in a ferret originated in Germany.
