Further studies with a diphtheria–tetanus–poliomyelitis vaccine

Experimental study of a further attenuated live measles vaccine of the Sugiyama strain in Iran

Red cell preservation: further studies with adenine.

I N A PREVIOUS COMMUNICATION’ we have shown that supplementing the acid citrate dextrose ( ACD ) preservative with small amounts of adenine (0.75 :: 0.25 ‘! per ml. ACD-blood) at the beginning of the storage period preserves satisfactory viability ( post-transfusion survival greater than 70 per cent ) of stored human erythrocytes for at least 5 weeks. Larger amounts of adenine were less effecti...

Further studies with xanthine oxidase inhibitors.

The osidase and dehydrogenase activities in the enzymes oxidizing xanthine can be differentiated by the use of certain inhibitors (1). The present study was designed to see if such inhibitors are specific for the reaction with oxygen, or whether these agents also block the transfer of electrons to cytochrome c and nitrate. Both reduced diphosphopyridine nucleotide and hypoxanthine were studied ...

Further studies with a selective medium for cultivating Neisseria gonorrhoeae.

A culture medium that is selective for the gonococcus and the meningococcus has been described recently (Thayer and Martin, 1964). The medium with Polymyxin and Ristocetin added permits isolation of the gonococcus from sites highly contaminated with other bacteria. Overgrowth of gonococcal colonies by the commensal bacterial flora present in rectal, vaginal, and cervical specimens is almost com...

Further Studies upon Anaphylaxis

the following points: A.?The incubation period of anaphylaxis, and its variations according as the injections of serum are made into the brain or otherwise, and according to the quantity of serum injected. B.?The results of treatment thermal and other of the injected serum, upon the production of supersensitiveness, and upon tlie toxicit}' of the serum. C.? The specificity of the anaphylactics....
