The glomerular mesangium: kinetics using radiolabeled ferritin and the effects of aggregated IgG.

A quantitative method for studying glomerular mesangial kinetics using radiolabeled native ferritin (125I-NF) is described. Groups of Sprague-Dawley rats were given injections of monomeric 125I-NF in a dose of 10 mg/100 g and sacrificed at 4, 16, and 36 hr. Radioactivity was measured in preparations of isolated glomeruli, spleen, and liver, and in blood. After initial uptake, a progressive decrease in the concentration of 125I-NF was observed in the mesangium and other organs. To examine the effect of one macromolecule on the mesangial kinetics of NF a separate group of animals was given aggregated human IgG (AHIgG) (40 mg/100 g) 4 hr prior to administration of 125I-NF. The administration of AHIgG did not alter the kinetics of 125I-NF in the mesangium, plasma, or spleen but the disappearance of 125I-NF from the liver was accelerated. Although the cellular mechanisms for uptake of NF and AHIgG are different, the presence of one macromolecule (AHIgG) within the mesangium did not affect the uptake and disappearance of another (NF). Thus, the glomerular mesangium has a relatively high capacity under normal circumstances.

Quantitative bacteriology of the vaginal flora.

Quantitative bacteriology was performed on vaginal secretions from healthy adult women. The analysis included a single sample from 17 college students and 35 samples from five volunteers collected at intervals of three to five days throughout the menstrual cycle. Mean concentrations in all 52 specimens were 10(8.1) aerobic bacteria/g and 10(9.1) anaerobic bacteria/g. The rank of predominant organisms, according to rates of recovery in concentrations of greater than 10(5) colony-forming units/g, was anaerobic and facultative Lacrobacillus species, Peptococcus species, Bacteroides species, Staphylococcus epidermidis, Corynebacterium species, Peotostreptococcus species, and Eubacterium species. Sequential samples collected throughout the menstrual cycle showed relatively consistent mean levels of anaerobes and a significant decrease in concentrations of aerobes in premenstrual specimens compared with those in the specimens collected in the week following onset of menses. Analysis of sequential specimens from each of the five individuals showed considerable variation in species recovered. These data indicate that the vaginal flora in healthy adult women is a dynamic ecosystem in which anaerobes are usually the numerically dominant bacteria.

[A clinical constelation in disuse: vitiligo, mastocytosis of the bone marrow, circulating heparinoid, chronic leg ulcer, hypoalbuminemia, ulcerative colitis and hepatic fibrosis].

We report an unusual case. Our patient had vitiligo, ulcerative colitis, hepatic fibrosis, hypoalbuminemia, bone marrow mastocytosis, a circulating heparinoid and chronic leg ulcers. The relationship between some of the components of this constellation seems logical. This is the case with bone marrow mastocytosis and circulating heparinoid. Also, between hypoalbuminemia and colitis and liver disfunction. On the other hand, the relationship between other features does not seem clear in the light of current knowledge.
