The first examples of complexes between a 4-membered amidinato-Group 13 metal(III) heterocycle and a transition metal fragment are formed in salt elimination reactions between Na[CpFe(CO)2] and [MX2(amid)], M=Al, Ga or In; X=Cl or Br; amid-=[(RN)2CBut]-; R=Pri or cyclohexyl (Cy). The formed complexes, [CpFe(CO)2M(X)(amid)] (4 examples) have been crystallographically characterised and subject to...

YSOZYME IN BLOOD, especially in white cells, has beemi demonstrated by several investigators. In the rabbit amid cat, Barnes’ found very little activity in lymphocytes obtained by thoracic duct cannulatiomi amid a large amount of activity in polymorphonuclear and mononuclear cells from peritoneal exudates. Sammons’ observed that lysozyme activity in exudates varied with the number of pus cells....

P REVIOUS STUDIES insdicate that L-cyst-eiise or related compounds may be importamst ins the metabolism of leukocytes. Thus L-cysteine, and to a lesser extent homocyst-eimse and glutathione, modify the leukopenia induced by nitrogen mustard.’ . 2 This protective effect appears to be specific in that mamsy highly reactive compoutsds w-ith structures closely related to L-cysteimse fail to prevent...
