    Notes: Summary Glomerular changes were morphometrically studied in renal biopsies of 27 cases of nephrosclerosis showing clinically benign or malignant hypertension and of 15 cases of mild mesangioproliferative glomerulonephritis with hypertension. In nephrosclerosis, there was a mild increase in mesangial matrix without cell proliferation. The degree of the mesangial changes varied little despite a large variation in blood pressure and showed no significant difference between benign and malignant hypertension. In mild mesangioproliferative nephritis with hypertension, mesangial matrix, as well as the number of mesangial cells, showed an increase of varying degree. A quantitative assessment of the mesangium was proved effective in differentiating the glomerular changes in nephrosclerosis from those in mesangioproliferative nephritis with hypertension.

    Notes: Summary The term “caloric irregularity” was coined to refer to a gross irregularity in the amplitude and/or frequency of a caloric-induced nystagmus, having a variable slow-phase velocity and prolonged duration. Twelve of 46 guinea pigs with experimentally induced perilymphatic fistula had irregular responses to the ice-water caloric test 1 week after creation of a fistula. The long-term vestibular consequences in animals with caloric irregularities were either resolution and return to normal function (i.e. caloric return) or continuing deterioration to canal paresis. Morphological examination of ears with caloric irregularity revealed that there had been partial collapse of the membranous labyrinth and the creation of a floating labyrinth.
