The NA"null" phenotype of a young man is caused by an Fc gammaRIIIB gene deficiency while the products of the neighboring Fc gammaRIIA and Fc gammaRIIIA genes are present.

A 27-year-old man with an allergy to house dust mites was found to lack the Fc gammaRIIIb on his neutrophils. Cell surface marker and PCR techniques were used to investigate possible reasons for this deficiency. Agglutination and immunofluorescence assays using the man's neutrophils together with NA1- and NA2-specific antibodies were negative, and there was no reaction with the Fc gammaRIII-specific mAb 3G8.

Inhibition of monocyte and polymorphonuclear granulocyte immune phagocytosis by monoclonal antibodies specific for Fc gamma RI, II and III.

We tested two Fc gamma receptor I (Fc gamma RI); six Fc gamma RII; and six Fc gamma RIII-specific monoclonal antibodies (mAb) for their capacity to inhibit monocyte and polymorphonuclear granulocyte (PMN) immune phagocytosis which is mediated by Fc gamma R. We used human red blood cells (rbc) coated with hIgG1 or mIgG1 as Fc gamma RI- and Fc gamma RII-specific target cells, respectively. The Fc gamma RI-specific mAbs 22.

[Absolute bioavailability of folic acid after oral administration of a folic acid tablet formulation in healthy volunteers].

5 mg folic acid were administered in two sessions to 9 female and 8 male healthy subjects within a balanced 2-way crossover trial either as one Folsan tablet (CAS 59-30-3, test preparation A) or as 2.5 ml of an injection solution (Folsan 2, reference preparation B). Folic acid was determined in serum and urine collected in fractions over 12 h after administration by means of a radioassay.

Steady state investigation of possible pharmacokinetic interactions of moxonidine and glibenclamide.

The aim of the study presented here was to determine possible pharmacokinetic interactions of moxonidine and glibenclamide at steady state in 18 healthy male volunteers. Multiple oral doses of 0.2 mg of moxonidine b.
