[Small scale efficient reproduction of El mice (author's transl)].

Epilepic anormaly strain of mice "El" derived from National Institute of Health, Japan were bred by sister-brother mating during the first 3 months and maintained thereafter by random mating at this laboratory. About 20% (21/101) of virgin females and 4% (2/49) of males were infertile and rate of delivering was relatively poor; mean delivery rate was 70.6%. Delivery rate were drawn after fourth litter. The mean litter size and weaning rate were 7.54 and 97.9%, respectively. Male El mice died following convulsion. Autopsy revealed the obstruction of urether, bleeding in the bladder and seminal vesicules. The time of 50% death was 166 days of age.

[99mTc-pertechnetate neck uptake in the evaluation of thyroid function--simple method with gamma camera and pinhole collimator (author's transl)].

The neck uptake ratio of 99mTcO4- was measured using a gamma camera and pinhole collimator. The patient was sit 2 m apart from the collimator surface and radioactivity was counted 20 minutes after injection. The whole body count with lead shield (Cc) and without shield (Cd), and natural background count (CBG) were measured. As the shield was utilized the B filter for conventional thyroidal 131I uptake test (lead plate of 1.3 cmx10 cmx10 cm) and it was placed over the anterior neck to cover the thyroid gland at the measurement of (Cc). Then 99mTcO4- neck uptake ratio was calculated as following: (formula: see text) The mean values were 5.3%, 4.5%, 3.1%, 11.2% and 20.7% in the group of euthyroid, hypothyroid, subacute thyroiditis, hyperthyroid state with chronic thyroiditis and Graves' disease, respectively. This method is very convenient and simple to perform following scintigraphy of the thyroid gland with pinhole collimator.

Mesangial IgA glomerulonephritis. Clinicopathological study of 85 cases.

A clinicopathological study was made on 85 cases of mesangial IgA glomerulonephritis and of 49 controls. Predominant incidence of male over female was noted in IgA glomerulonephritis. The disease developed insidiously in a considerable number, and occupied 68% of chance proteinuria and/or hematuria. Macrohematuria was often experienced, but in a statistical comparison with controls, no specific features were observed clinically except that hypertensive cases were rarely encountered in this disease, which may reflect the better prognosis. Serum IgA levels were not different significantly in two groups. Histological changes were those of various natures and intensities, and no specific type of lesions were observed. The negative staining of C1q and C3PA in glomeruli of IgA glomerulonephritis offered no possibility to elucidate either of the complement pathways as active.
