Immunoreactive endorphin peptides (ir EP) and prolactin (PRL) were measured by radioimmunoassay in venous blood from the umbilical cords of 86 neonates, 23 postpartum mothers, and 40 randomly selected blood bank donor control subjects. We also assaye

A large amount of data suggests that a wide variety of cells and tissues contain cell-specific endogenous inhibitors of mitosis which are not species-specific. Increasingly, it appears that these chalone inhibitors are actually relatively small polyp

The cell-specific inhibition of PHA-stimulated lymphocyte transformation by splenic ultrafiltrates (50000-30000 D) differed in its kinetics from either cyclohexamide or cytosine arabinoside inhibition. Parallel inhibition of acid-soluble precursor [

Aqueous extracts of various lymphoid tissues, but not of non-lymphoid tissues, contain a species-non-specific but cell-specific inhibitor of the transformation and DNA synthesis of PHA-stimulated human lymphocytes which is apparently not cytotoxic an

Ultrafiltered splenic extracts (30,000–50,000 daltons) were specifically cytotoxic in crowded cultures of murine leukemic lymphoblasts but were only inhibitory toward normal lymphocytes or sparse cultures of leukemic cells. This expression of cytot

A solution of ribonucleic acid when mixed at 37 ° with a solution containing serum albumin and gelatin gives a turbidity which may be measured at 400 mμ. The decrease in this turbidity with enzyme action permits the quantitative estimation of 1–5

The dermal chemistry of the response of the -connective tissue to local inflammation has been shown previously to involve three major changes with injury: 1) a marked loss of acid polysaccharides; 2) a profound loss of insoluble collagen; and 3) the

pH variation of the Michaelis constant and maximum velocity for the RNAase (polyribonucleotide 2-oligonucleotidotransferase (cycling), EC 2.7.7.16) depolymerization of RNA was studied at 35° in 0.1 M sodium chloride. A change in slope of both pH−p

Fibroblasts, both mouse and human, can induce collagenolytic enzyme, probably via the depression of an operon. This depression can be produced by cortisol, oxyphenylbutazone or indomethacin. The induced collagenase is released easily from within the
