suppressor cells in the spleen of tumor-allosensitized mice.c57bl/6 mice were sensitized i.p. with 20 x 10(6) p-815 mastocytoma cells. spleen and lymph node cells from these tumor-allosensitized mice become hyporesponsive in mixed-lymphocyte culture. the hyporesponsiveness appears to be due to the presence of suppressor cells. these suppressor cells can be demonstrated by their ability to inhibit the mixed-lymphocyte culture reactivity of normal mouse spleen cells. suppressor activity in the spleen of tumor-allosensitized mice remains long after cytotoxi ...1977141979
fluorescence of human liver alanine aminopeptidase.fluorescence of human liver alanine aminopeptidase has been attributed to tryptophan fluorescence. the fluorescence maximum is at 330 nm, 20 nm lower than that for free tryptophan, suggesting that most of the enzyme tryptophans are in a nonpolar environment and are shielded from solvent. quenching of enzyme fluorescence by iodide, pyridine, and n-methyl nicotinamide also demonstrates that enzyme tryptophan residues are largely buried and inaccessible to solvent. those accessible are in negativel ...1977143669

studies on the occurrence of peptococcus indolicus and corynebacterium pyogenes in abscesses in swine, and on the occurrence of pc. indolicus in apparently normal skin and mucous membranes of piglets.pc. indolicus was isolated from 42.7% and cb. pyogenes from 48.7% of 150 pus-samples from abscesses in pigs (slaughter-house material, table i). in 41 specimens the two organisms were found together. further, pc. indolicus was demonstrated in 22.4% of 290 swabs from apparently normal skin and mucous membranes of piglets (autopsy material, table ii). by gel diffusion analysis the strains of pc. indolicus were referred to the serotypes b, c, d, e, or f. the type distribution (table iii) possibly r ...197898755
production and chemical studies of protease from bacillus subtilis (sh-6) egyptian strain.bacillus subtilis (sh-6) egyptian strain, isolated from hides, gave the highest protease activity. luxurious growth and protease production were obtained by the use of a medium containing 8% of potato starch, 0,1 m of ammonium phosphate as carbon and nitrogen sources. results indicate that borate buffer exerted a deleterious effect on the protease production. comparing citrate and phosphate buffers, it was found that citrate gave lower protease activity than phosphate. there is a positive respon ...197898932
biological variation of immunoglobulin concentrations in normal human tears related to age and sex.single radial immunodiffusion method was used to measure the concentration of igg, iga, igm and igd in tears of 220 healthy individuals aged from 2 to 86 years. relation of the values to age and sex has been evaluated statistically by regression analysis method. mean iga level was 30.7 mg/100 ml. igg could be detected in 200 samples and the level was less than 1 mg/100 ml. igm was detected in only 7 samples and the value was less than 1 mg/100 ml. igd could not be detected in any of the sample. ...197898956

ineffectiveness of prophylactic intrathecal methylprednisolone in myelography with aqueous media.the effectiveness of prophylactic intrathecal methylprednisone (mp) in preventing arachnoiditis from iocarmate myelography was studied. monkeys were injected intrathecally with locarmate, mp, or a combination of the two. twelve weeks later the severity of arachnoiditis was determined in each animal. there was no significant prophylactic effect of intrathecal mp on arachnoiditis from locarmate. some arachnoiditis was found in control animals treated with mp alone.197899764
effect of cortisone on aspartate and alanine aminotransferases in a desert lizard.1. liver and serum aspartate aminotransferase (got) and alanine aminotransferase (gpt) activities were measured in a hibernating desert lizard, uromastix hardwickii. the levels of both enzymes were found to be lower in hibernation than during the active period, particularly in the liver. 2. after intramuscular injection of 2 mg of cortisone acetate there was a rapid rise in the levels of these enzymes with a peak of 18 hours (got) and 12 hours (gpt). 3. the response of both enzymes to cortisone ...1978149452
a study of endotoxemia in ulcerative colitis and crohn's disease. i. clinical study.endotoxin (lipopolysaccharide, lps) and lps antibody in the blood were studied in 61 cases of ulcerative colitis (u.c.) by radioimmunoassay. lysozyme (lzm) concentration was also studied by the turbidimetric method. as a result, it was found that the blood lps value as well as serum lzm concentration reflects the clinical observations. the case of endotoxemia in the active phase group showed a positive correlation between the lps value and lzm concentration. lps antibody which could not be detec ...1978150200
