Relative proportions and numbers of helper [OKT4(+)] and suppressor [OKT8(+)] peripheral blood lymphocytes were examined in 32 young patients during the acute phase of rheumatic fever. No significant decrease in percentage T cells during acute rheumatic fever was noted in comparison to normal children controls from the same population. A decrease in absolute numbers of OKT4(+) T cells was also noted in acute rheumatic subjects not receiving corticosteroids (P less than 0.05). In addition, a significant decrease was documented in both proportions and total numbers of OKT8(+) putative suppressor cells during acute rheumatic attacks. C-reactive protein binding to T-lymphocyte subsets showed no preferential reactivity in vivo for suppressor or helper T cells. Antigen-reactive T lymphocytes identified with the T29 mouse hybridoma reagent showed similar proportions and numbers in rheumatic children as were noted in controls. The present data indicate profound alterations in both helper- and suppressor-cell types in the peripheral blood profile of children with acute rheumatic fever.

Molecular cloning and chromosomal mapping of a human locus related to the transforming gene of Moloney murine sarcoma virus.

Human DNA was analyzed for the presence of sequences homologous to the transforming gene (v-mos) of Moloney murine sarcoma virus. A single 2.5-kilobase pair (kbp) EcoRI-generated fragment of human DNA was identified by using cloned v-mos as probe. This DNA was molecularly cloned in a bacteriophage vector. By heteroduplex and restriction enzyme analyses, this human DNA fragment, designated c-mos (human), contained a 0.65-kbp region of continuous homology with v-mos and was present as a single copy in human DNA. By testing for the presence of c-mos (human) in somatic cell hybrids possessing various numbers of human chromosomes, as well as in subclones of such hybrids, it was possible to assign c-mos (human) to human chromosome 8.

A planned prospective evaluation of the anti-infective property of varying quantities of expressed human milk.

This paper comprises 261 low birth weight infants who were divided into four groups with different feeding schedules. Group I--expressed human milk for all the feeds; Group II--human milk for half the feeds and the nursery formula for the rest; Group III--colostrum, 20 ml three times a day along with the nursery formula; and Group IV--control--only the nursery formula. The groups were matched by means of a randomized block design for identifiable factors which could predispose to the occurrence of infection. Infections were found to be significantly less in the groups which received human milk (p less than 0.001).

Studies on the intestinal disaccharidases of the pigeon. II. Subcellular localization and solubilization.

In the pigeon, 70-80% of the activities of maltase (alpha-D-glucoside glucohydrolase EC 3.2.1.20), sucrase (alpha-glucohydrolase, EC 3.2.1.48), isomaltase (dextran 6-alpha-D-glucan hydrolase, EC 3.2.1.10) and glucoamylase (1,4-alpha-D-glucan glucohydrolase, EC 3.2.1.3) were found to be localized in the brush-border membrane of intestinal epithelial cells. Of the total glycosidase activities in the mucosal homogenate, nearly 60 to 70% were recovered in the microsomal (105 000 X g) fraction, about 30% in the mitochondrial (22 000 X g) fraction and less than 5% from the cytosol (105 000 X g supernatant) fraction. The hydrolases were solubilized by digestion with papain but not with trypsin, and the phosphate ion had a protective effect in the solubilization. Amongst detergents, Triton X-100 but not sodium deoxycholate, was found to truly solubilize these enzymes.
