Further studies on the transmission of Staph. aureus.

of patients died from complications of endocarditis at about the time of completion of a six-weeks course of antibiotics adjudged to be curative, and, although no detailed study was made at necropsy concerning the viability of the bacterial colonies seen, their appearance gave no grounds for hope that, in these cases, several weeks less of treatment would have sufficed. In addition a case has a...

The effect of ketamine on synaptic transmission and synaptic plasticity in CA1 area of rat hippocampal slices

The effect of ketamine (1-100 µM), which has NMDA receptor antagonist properties, on synaptic transmission and long-term potentiation (LTP) in CAl area of rat hippocampus was examined in vitro. Field potentials were recorded in pyramidal cell layer following Schaffer collateral stimulation. Primed-burst stimulation (PEs) was used for induction of LTP. The amplitude of population spiks (PS) was ...

Further studies on polyribophosphate.

In previous reports (2, 3) it has been demonstrated that the type-specific substance of Hernophilus injluenzae, type b, is a polymer of ribose and phosphate, i.e. a polyribophosphate. Similar to ribonucleie acid, PRPI consists of a long chain of ribose units connected by 3,5-phosphate diester linkages. However, instead of a purine or pyrimidine on carbon 1 of ribose, as is the case in ribonucle...
