We herein report a very rare case of a patient suffering from simultaneous occurrence of three immune disorders, i.e. Hashimoto's thyroiditis, sarcoidosis and minimal change glomerular disease. A 66-year-old man was admitted to our hospital for evaluation of nephrotic syndrome. Six months before admission, he was pointed out as having positive proteinuria, hypoalbuminemia and associated pretibial pitting edema. Initial laboratory data showed high gammaglobulinemia, high titers of both antimicrosomal and antithyroglobulin antibodies with normal thyroid function. Chest X-ray and CT scan revealed bilateral hilar lymphadenopathy with interstitial shadow. Ga-citrate scan disclosed positive accumulation in the thyroid glands, the mediastinum, the lungs and the kidneys. The diagnosis of minimal change nephritic syndrome and pulmonary sarcoidosis was made, based on the findings of transbronchial lung biopsy and kidney biopsy. After one and a half months of admission, thyroid function had gradually deteriorated. The histological findings of the thyroid were consistent with the features of Hashimoto's thyroiditis. Treatment with prednisolone and cyclophosphamide resulted in a decrease in urinary protein excretion, reduction in the size of mediastinal lymphadenopathy and disappearance of positive findings of Ga-citrate scan in the thyroid glands and the kidneys. Simultaneous occurrence of minimal change-glomerular disease, sarcoidosis and Hashimoto's thyroiditis in our case suggests that similar immunological abnormalities may be involved in the pathogenesis of the diseases.

To confirm our hypothesis that the sex and age of cynomolgus monkeys influences the effect of training, we employed a new training technique designed to increase the animal’s affinity for animal care personnel. During 151 days of training, monkeys aged 2 to 10 years accepted each 3 raisins/3 times/day, and communicated with animal care personnel (5 times/day). Behavior was scored using integers between −1 and 5. Before training, 35 of the 61 monkeys refused raisins offered directly by animal care personnel (Score −1, 0 and 1). After training, 28 of these 35 monkeys (80%) accepted raisins offered directly by animal care personnel (>Score 2). The mean score of monkeys increased from 1.2 ± 0.1 to 4.3 ± 0.2. The minimum training period required for monkeys to reach Score 2 was longer for females than for males. After 151 days, 6 of the 31 females and 1 of the 30 males still refused raisins offered directly by animal care personnel. Beneficial effects of training were obtained in both young and adult monkeys. These results indicate that our new training technique markedly improves the affinity of monkeys for animal care personnel, and that these effects tend to vary by sex but not age. In addition, abnormal behavior and symptoms of monkeys were improved by this training.
