Right: lateral view oflumbar spine showing narrowing ofdisc spaces ofT12 andL I and kyphos between L2 and L4, pseudo-Schmorl's nodes at upper and lower surfaces of T12, and bridging anterio-lateral osteophytes between L2 and L4. Only vestiges ofposte...

Our purpose was to determine the specificity of l-arginine (l-Arg)-induced conducted signals for intra- vs. extracellular actions ofl-Arg. Diameter and red blood cell velocities were measured for arterioles [18 ± 1.6 (SE) μm] in the cremaster muscle of pentobarbital sodium-anesthetized (Nembutal, 70 mg/kg) hamsters ( n = 53). Remote (conducted) responses were viewed ∼1,000 μm upstream from the ...

INTRODUCTION. IN a recent review of worlcl tuberculosis mortality, MIcDougall (1950) demiioinstrated that niortalitv has declined in most of the countries which publish reasonablv reliable statistics. Of twentv-nine countries considered, only in Portugal andl Scotland were the crude death rates less in 1937-:39 than in 1947-49. '1'he average aninual rates quoted for Northern Ireland, 91.2 and 6...

Opening of mitochondrial ATP-sensitive (mitoKATP) channel with diazoxide induces an early phase (EP) of cardioprotection. It is unknown whether diazoxide also induces a delayed phase (DP) of cardioprotection. Because nitric oxide (NO) modulates ATP sensitivity of the KATP channel, we hypothesized that NO may play a role in diazoxide-induced cardioprotection. Diazoxide (1 mg/kg) was administered...

Gibberellic acid (GA) enhances the synthesis otf a-amylase andl ribonutclease in isolated aleurone layers andl this process is inhibited by abscisiin. Removal of gibberellic acid in mid-course of a-amylase productioni results in a slowing down of a-amylase synthesis, suggesting a continued requirement of GA for eiizyme synthesis. This is paralleled by a continuous requirement for RNA synthesis....
