the complete amino acid sequence of actins from bovine aorta, bovine heart, bovine fast skeletal muscle, and rabbit slow skeletal muscle. a protein-chemical analysis of muscle actin differentiation.complete amino acid sequences for four mammalian muscle actins are reported: bovine skeletal muscle actin, bovine cardiac actin, the major component of bovine aorta actin, and rabbit slow skeletal muscle actin. the number of different actins in a higher mammal for which full amino acid sequences are now available is therefore increased from two to five. screening of different smooth muscle tissues revealed in addition to the aorta type actin a second smooth muscle actin, which appears very simil ...1979499690
wheat germ agglutinin blockage of chlamydial attachment sites: antagonism by n-acetyl-d-glucosamine.addition of 2 to 10 micrograms of wheat germ agglutinin (wga), a lectin from triticum vulgaris specific for n-acetyl-d-glucosamine, per ml to suspensions of mouse fibroblasts (l cells) blocked the attachment of 14c-labeled chlamydia psittaci 6bc to the l-cell surface. wga and strain 6bc competed for similar sites on l cells, but once bound, one was not replaced by the other. n-acetyl-d-glucosamine, but not other monosaccharides of related structure, antagonized the blocking action of wga. lectin ...1979500195

major elements in milk of the west african dwarf goats as affected by stage of lactation.tweove adult west african dwarf (fouta djallon) does, about 2 years old and weighing from 25 to 28 kg were kept for lactation studies lasting two 19-week periods. during these periods the does were hand-milked twice daily and the daily samples were bulked for each animal for subsequent analysis. the results showed that the colostrum was much richer in its content (g/kg) of na 1.44 +/- 0.17, k 3.38 +/- 0.22 and cl 4.83 +/- 0.29 than the mature milk which contained (g/kg) na 0.65 +/- 0.09, k 1.57 ...1979500883
high level of human growth hormone (hgh) in cerebrospinal fluid patients with pituitary tumors.six patients with suprasellar extension of pituitary hgh-secreting tumors showed the cerebrospinal fluid (csf) content in human growth hormone (hgh) to be very high, i.e. 164.3 +/- muu/ml (mean +/- sem) (range 8.4--413.8 muu/ml) as compared to ten patients with uncomplicated acromegaly whose values were 50-fold lower, i.e. 3.4 +/- 0.5 muu/ml (range 0.6--7.0 muu/ml), and nine patients with suprasellar extension of other pituitary tumors, showing also low levels of hgh in the csf, i.e. 2.9 +/- 0.8 ...1979504962

cold acclimation in the secretory responses of the isolated exocrine pancreas of the rat.1. the secretory function of the isolated and perfused exocrine pancreas has been studied in the course of cold acclimation in rats that were fed at an ambient temperature of 1 degrees c in an artificial climatic room.2. a series of experiments was carried out in early autumn (autumn series). the sums of the outputs of protein, amylase, zymogen protease, lipase, and juice flow in samples collected for a total of 30 min during and after 5 min stimulation with different concentrations of cholecyst ...1979501617
vaginal oxytetracycline concentrations.although tetracycline preparations are widely used in departments of genitourinary medicine, or sexually transmitted diseases clinics, little is known of the concentrations of these preparations in genital secretions. for this reason a microbiological method was used for estimating oxytetracycline concentrations in vaginal secretions. these concentrations varied from 0.6 to 6.5 microgram/ml in 19 women who had had sexual contact with a man with non-specific urethritis and who were taking oxytetr ...1979509190

juxtapapillary choroiditis in association with rising antichlamydial antibody.we present the case of a 21-year-old girl with a uniocular juxtapapillary choroiditis. during the course of her illness the titre of antichlamydial igg increased from 1/32 to 1/4096 against chlamydia trachomatis tric serotypes j and c, and antichlamydial igm appeared in her blood. toxoplasma dye test was positive at a level of 1/128 but no increase in the titre of antibody was detected during the course of her infection. the relevance of these findings to her ocular lesion is discussed.1979508692
