Pyrazinoic Acid

A progressive reduction of renal blood flow and glomerular filtration rate induced by the stepwise clamping of a Goldblatt clamp increases the urate over creatinine clearance ratio from 1.2 to 1.9 in normal urate-secreting Dalmatian dogs. These clearance data support the existence of a predominant postreabsorptive secretory flux of urate in the normal Dalmatian dog. In contrast, in Dalmatians loaded with pyrazinoic acid which suppresses urate secretion, net reabsorption of urate is unmasked and the urate over creatinine clearance ratio decreases with the progressive reduction in glomerular filtration rate (down to 0.44). It is concluded that the net reabsorption of urate measured by conventional clearance techniques after pharmacologic depression of the urate secretory flux probably reflects true urate reabsorption in the nephron of this species.

Sine Wave Gratings

The effect of change in spatial frequency on the alternation rate of two crossed gratings was measured. The rate was found to decrease with increase in spatial frequency, but to change only little with contrast. Low alternation rate was observed for crossed square-wave gratings compared to crossed sine-wave gratings; here the rate of rivalry is largely dependent upon the presence or absence of the first three harmonic components rather than the higher harmonics which contribute to the sharp edges of the square wave. The results are compared with those for some ambiguous figures.

Late Selection

Four studies are reported that demonstrate effects of attention on early perceptual processes. These studies show that directing attention to stimulus location influences perceived brightness, perceived length, and the overall organisation of the Müller-Lyer figure and ambiguous figures. Since in all four studies the dependent measure was dissociated from the attentional instructions, the results are not open to traditional criticism of late-selection advocates, and therefore provide strong support for early-selection views of attention.
