Abstract
Group A streptococci and their isolated cell walls, normally resistant to egg-white lysozyme and the lysosomal enzymes of human phagocytes, were converted to lysozyme-sensitive forms by partial removal of cell wall carbohydrate, substitution of free amino groups, and by saponification of O-acyl groups. The resultant modified streptococcal cell walls showed rapid degradation when treated with leukocyte granule extract derived from human peripheral blood polymorphonuclear leukocytes and monocytes and when subjected to phagocytosis by living human leukocytes. These results indicate that the factors responsible for lysozyme resistance of the group A cell wall also influence its resistance to human leukocyte granule enzymes and suggest that the chemical composition of the cell wall, in addition to the presence of cell wall carbohydrate, determines this resistance.

Abstract
The present study was directed toward determining the role of the kidney in the metabolism of various classes of serum proteins and to define the urinary protein excretion patterns and the pathogenesis of disorders of protein metabolism in patients with proteinuria. To this end, the metabolic fates of a small protein, lambda-L chain (mol wt 44,000), and a protein of intermediate size, IgG (mol wt 160,000), were studied in controls and patients with renal disease. Controls metabolized 0.28%/hr of circulating IgG and 22.3%/hr of circulating lambda-L chain. All the IgG and 99% of the lambda-L chain was catabolized with the remaining lambda-L chain lost intact into the urine. The kidney was shown to be the major site of catabolism for small serum proteins. Three distinct disorders of protein metabolism were noted in patients with renal tubular disease and tubular proteinuria, glomerular disease (the nephrotic syndrome), and disease involving the entire nephrons (uremia), respectively. Patients with renal tubular disease had a 50-fold increase in the daily urinary excretion of 15-40,000 molecular weight proteins such as lysozyme and lambda-L chains. Serum IgG and lambda-L chain survivals were normal; however, the fraction of the over-all lambda-L chain metabolism accounted for by proteinuria was increased 40-fold whereas endogenous catabolism was correspondingly decreased. Thus, tubular proteinuria results from a failure of proximal tubular uptake and catabolism of small proteins that are normally filtered through the glomerulus. Patients with the nephrotic syndrome had a slight increase in lambda-L chain survival whereas IgG survival was decreased and the fraction of IgG lost in the urine was markedly increased. Here, abnormal glomerular permeability to proteins of intermediate size is the basic abnormality. Patients with uremia had a normal IgG survival but a four to 10-fold prolongation of lambda-L chain survival due to loss of entire nephrons, the major site of metabolism of these proteins. This results in an increase (up to 10-fold) in the serum concentration of lambda-L chain, lysozyme, and other small biologically active proteins, a phenomenon that may be of importance in causing some of the manifestations of the uremic syndrome.

Abstract
Lysozyme turnover studies with (125)I-labeled human lysozyme were carried out on 22 patients, viz. nine control patients, seven nephrological patients with varying degrees of renal insufficiency, including three bilaterally nephrectomized patients, and six hematological patients with disturbed turnover of the neutrophilic granulocytes. It was found that plasma lysozyme has a rapid turnover with a fractional catabolic rate of 76%/hr of the plasma content. Lysozyme catabolism varied with the endogenous creatinine clearance; in addition however, extrarenal sites of catabolism were demonstrated since lysozyme could be broken down in the anephric patients, although only at a rate amounting to about 15% of the rate found in persons with intact kidneys. In the uremic patients the increased plasma lysozyme concentration was due to decreased rates of catabolism; in the hematological patients the increased plasma lysozyme level was due to increased rates of synthesis which supports the hypothesis that plasma lysozyme mainly stems from disintegrating neutrophilic granulocytes. Furthermore, it was shown that in the nonhematological patients examined, the rate of synthesis varied with the endogenous creatinine clearance.

Abstract
The stimulation of DNA synthesis in mouse (C57BL) macrophages explanted in vitro was demonstrated after treatment with conditioned medium or infection with SV40. In the latter case, induction of SV40 T antigen was detected before TdR-(3)H incorporation. Even though all macrophages were infected (T antigen-positive), they exhibited considerable pleomorphism, accompanied by functional differences. Permanent lines of SV40-transformed macrophages were eventually established, and one clone was isolated which replicates indefinitely and has many properties of primary macrophages: high acid phosphatase and phagocytic activity, lysozyme production, and specific antigenic determinants. These cells differ from normal macrophages in that they contain the SV40 genome, can be trypsinized, and do not require conditioned medium for continued replication.

Abstract
The kinetics of blood neutrophils was investigated by means of the in vitro radioactive diisopropyl fluorophosphate method in 35 patients with a chronic, steady-state neutropenia. There were 17 patients in whom the half disappearance time of neutrophils was normal. In 10 of these patients, the production of neutrophils was low and in 7, production was normal. In 18 patients the half disappearance time of neutrophilic granulocytes was shorter than normal. The production of neutrophilic granulocytes was low in five of these patients, normal in eight patients, and increased in five. An attempt was made to correlate other laboratory measurements with the kinetic picture, but no relationship was found; the marrow neutrophil reserve as measured by endotoxin or cortisol injection; marrow cellularity on aspiration or biopsy; in vitro-labeling index with (3)HTdR; or serum lysozyme concentration proved of no value in identifying the various kinetic groups. The only finding that seemed to correlate with the kinetic picture was the presence or absence of splenomegaly. In 12 of the 18 patients with a short half disappearance time, splenomegaly was present whereas in 15 of 17 patients with a normal half disappearance time, there was no splenomegaly. Of 20 patients with greater than 1000 neutrophils per mm(3), 17 were found to have a normal total-blood neutrophil pool. Thus these patients, with many of their cells marginated, agree to have a "shift neutropenia."Myelocyte to blood transit time and myelocyte generation time, as measured in seven patients by in vivo labeling with diisopropy fluorophosphate, proved to be essentially normal. Thus, it appears that in chronic neutropenia, increased or decreased production of neutrophils is accomplished by increasing or decreasing early precursor input into the system.

Abstract
Lysozyme turnover in the rat was studied with (125)I-labeled rat lysozyme. It was found that plasma lysozyme has a rapid disappearance rate with a half-life of 75 min. The rate of synthesis was calculated at 3.4 mug/min per 100 g rat. This rate of synthesis was compared with figures from the literature for the turnover rate of neutrophilic granulocytes, and the data were consistent with the concept that disintegrating neutrophils are the main source of plasma lysozyme. The distribution of enzymatic lysozyme activity and of radioactive lysozyme was studied in several organs. Very high enzymatic activity was found in leukocytes as were considerable activities in lungs, kidneys, bone marrow, spleen, and intestine; little enzymatic activity was found in the urine. High radioactive levels as compared with plasma radioactivity were demonstrated only in the kidneys. This indicates that of the organs studied, the kidney is the predominant site of storage and destruction of plasma lysozyme. Lysozyme was found to disappear only slowly from the kidneys over a period of 4 days. The data obtained seem to indicate that lysozyme or a lysozyme degradation product precipitable by trichloroacetic acid was released in small amounts from the kidneys to plasma throughout this period.

Abstract
The ultraviolet circular dichroism spectra of human lysozyme are presented. Effects of pH and added inhibitor (N-acetyl-D-glucosamine) were examined and the results were compared with similar measurements of hen egg-white lysozyme. The near-ultraviolet CD spectral bands are substantially different in the human and hen egg-white enzymes. In addition to marked dissimilarities in the spectral interval 260-300 nm, an unusual CD band occurs at an anomalous wavelength (313 nm) in human lysozyme. The pH dependence of the latter suggests a possible interaction, absent in hen egg-white lysozyme, between a tryptophan and a tyrosine residue. Analysis of the spectra furthermore suggests lesser net rotational strengths of tryptophan bands in hen egg-white lysozyme than in human lysozyme, although the latter has one less tryptophan residue. The relationship between the CD spectra and the sequence differences of the proteins is discussed, as well as the CD spectra (published by others) of a closely related protein, bovine alpha-lactalbumin. Contributions of cystine residues to the spectra are examined in the light of possible differences in chirality of one of the four disulfide bridges.The far-ultraviolet CD spectra of human and egg-white lysozyme are quite similar, though not identical. In view of the pronounced differences in side-chain optical activity, and of the effect of pH variation on the far-ultraviolet CD spectrum of human lysozyme, it is likely that at least part of the observed difference in spectra is due to nonpeptide optical activity, and that the proteins have a secondary structure in common.
