中井 義 尚 ・高折 修二 The effects of central depressants on the evoked potential and ensued rhythmic after-discharges in the auditory cortex by a series of single click stimuli in cats were previously reported (1). In contrast to a progressive depression of the evoked potential by urethane and ethyl alcohol, the intravenous infusion of pentobarbital sodium, chlo ralose and chlorpromazine produced consi...

The role of sympathetic and other pressor systems in the development of fulminant hypertension induced by baroreceptor deafferentation is still unclear. We studied the effects of acute hypertension produced by bilateral dorsomedullary knife cuts lateral to the nucleus tractus solitarii (DMK-cut) on plasma norepinephrine (NE), epinephrine (E), and vasopressin (VP) in conscious, tail-artery-cannu...

(approximately 600--1000 μmol m s) and O2 uptake in darkness were measured in needles of control, irrigated and irrigated-fertilized trees of Norway spruce (Picea abies (L.) Karst.). Measurements were made at 20 °C and at high CO2 concentrations. The results suggest that, at given times of the year, a major part of the variation in gross photosynthesis of current-year and one-year-old needles a...

Human neutrophils preloaded with chlortetracycline, commonly used as a probe of membrane-bound calcium, demonstrate a prompt decrease in fluorescence when exposed to surface stimuli such as the chemotactic peptide fMet-Leu-Phe. The fluorescence response was highly sensitive to preincubation with prostaglandin Ex. This effect was apparently not due to elevated levels of CAMP sink exogenous dibut...
