A comparison of Ca2+-, Mg2+-ATPase and alkaline phosphatase activities of rat incisor pulp
A plasma membrane preparation derived from incisor pulps of 250-g rats was used as the source of alkaline phosphatase and an ATPase activated by either Ca2+ or Mg2+. Properties of the two enzymes were then compar...

Acute toxicity of rhomotoxin in animals
The LD50 of rhomotoxin in mice was 0.522 mg/kg i.p. In dogs, its effective antihypertensive dose was 3.5µg/kg i.v. By 6 times the above dose, arrhythmias and changes of T wave occurred in most dogs, however, all ...

Applying the generalized step-function to solve the bending problems of nonuniform beams with variable cross section
The bending problems of nonuniform beams with variable cross-section can be approximated by that of a step beam under sectionally uniform load (including both concentrated forces and couples). In this paper, t...
