| radioiodide uptake in brain, csf, thyroid, and salivary glands of audiogenic seizure mice. | dba/2j (dba) mice are susceptible to audiogenic seizures (ass) in an age-dependent manner. anion transport as measured by radioiodide uptake was determined in thyroid gland, salivary gland, skeletal muscle, cerebral cortex, cerebellum, brainstem, and csf from these mice at various ages. anion transport was also determined in c57bl/6j(c57) mice, an as-resistant strain. in thyroid, dba mice had an enhanced ability to concentrate iodide at 21 days of age when they have maximal as susceptibility, as ... | 1984 | 6745222 |
| argininosuccinic acid synthetase deficiency in a hamster cell line and its complementation of argininosuccinic aciduria human fibroblasts. | unlike normal human cells, cultured fibroblasts from patients with argininosuccinic aciduria cannot synthesize arginine from citrulline because they have a deficiency of argininosuccinic acid lyase (asl). we have found that v79, a chinese hamster cell line, cannot grow on citrulline. although these cells show a normal uptake of citrulline and have levels of asl comparable to a human cell line (hela) which can grow in citrulline-containing medium, v79 cells have less than 5% of the argininosuccin ... | 1980 | 6777600 |
| intestinal microflora and aging: age-related change of enzymes in the liver and the small intestine of germ-free and conventional rats. | the activities of various enzymes involved in detoxication and carbohydrate metabolism in the liver and the gastrointestinal tract of germfree (gf) and conventional (cv) rats, 8 and 40 weeks' old, were measured in relationship to intestinal microflora and aging. in 8-week-old rats, the activities of nitroreductase (nr) and aniline hydroxylase (ah) in the liver, and of alkaline phosphatase (alp), maltase and lactase in the duodenum were higher in gf than in cv rats, but the activities of arginosu ... | 1981 | 6796785 |
| comparison of argininosuccinate synthetase from young and old rat livers. | properties of argininosuccinate synthetases (ass), including immunological properties and heat stability, from young and old rats were quite similar. however the degradation rates of ass from young and old rats were found to be different as shown in the experiment using the double labeling technique. three forms of this enzyme from young and old rat livers were separated by deae-sephadex a-50 column chromatography, and they were called ass 1, 2 and 3 in order of elution. the degradation rate of ... | 1981 | 6798716 |
| [final host specificity of sarcocystis species transmitted by dogs (authors's transl)]. | dogs and raccoons were fed muscle of various intermediate hosts that had been infected either naturally or artificially wit sarcocystis species transmitted from dogs. the muscle samples used for the experiments contained cysts of the following species: s. sp. of the donkey, s. bovicanis of cattle, s. ovicanis and s. sp. of sheep, s. suicanis of pigs, or s. capracanis and s. sp. of goats. in all trails, the dogs shed sporocysts of the sarcocystis species concerned after a typical prepatency. in t ... | 1981 | 6798774 |
| monoclonal antibodies specific for cell culture mycoplasmas. | mycoplasma infection of cell cultures is still a major problem in some laboratories. although several methods can be used for their detection, identification is normally by serological procedures. as no commercial source for the necessary antibodies is available we have prepared monoclonal antibodies to the five mycoplasma species that account for the majority of cell culture infections. these antibodies have been characterized by the growth inhibition test (git), immunofluorescence, and enzyme ... | 1982 | 6811415 |
| properties of an aldose reductase from pig lens. comparative studies of an aldehyde reductase from pig lens. | two monomeric nadph enzymes from pig lens, an aldehyde reductase and an aldose reductase, have been characterized. the aldose reductase is obtained in a pure form. the aldehyde reductase, usually called hexonate dehydrogenase, is the same protein as that was recently isolated from pig liver [branlant, g. and biellmann, j.f. (1980) eur. j. biochem. 105, 611-621]. the aldose reductase is shown to have a number of properties in common with the aldehyde reductase, namely its physico-chemical propert ... | 1982 | 6819141 |
| pituitary and chorionic gonadotrophic control of ovarian function during early pregnancy in equids. | concentrations of fsh, lh, chorionic gonadotrophin (cg) and progesterone were measured during early pregnancy in mares and donkeys carrying normal intraspecies and transferred extraspecies conceptuses. a secondary rise in progesterone concentrations occurred in normal intraspecies horse and donkey pregnancy soon after the appearance of cg but fsh concentrations continued to fluctuate and were not influenced by cg production. in donkeys carrying transferred horse conceptuses fsh concentrations fe ... | 1982 | 6820064 |
| differentiation of meat according to species by the electrophoretic separation of muscle lactate dehydrogenase and esterase isoenzymes and isoelectric focusing of soluble muscle proteins. | species identification of fresh meat can be readily achieved by serological techniques with the limitation that closely related species, such as sheep/goat, cattle/buffalo and horse/donkey, cannot be differentiated. we have examined electrophoretic techniques with particular reference to the identification of meat from closely related species. the results showed that beef and buffalo meat and meat from red and grey kangaroos could be clearly distinguished by isoelectric focusing on polyacrylamid ... | 1983 | 6838437 |
| a biochemical comparison of the in vitro replication of a virulent and an avirulent strain of venezuelan encephalitis virus. | the virulent venezuelan equine encephalitis (vee) virus strain, trinidad donkey (trd) and its vaccine derivative strain tc-83, demonstrated biological and biochemical differences in their replication. these two viruses had similarly shaped growth curves; however, trd virus-infected cells produced significantly more infectious virus than did the tc-83 virus-infected cells during the very early period of the replication cycle. trd virus inhibited host cell protein synthesis in vero cells earlier t ... | 1983 | 6842187 |
| molecular cytogenetics of the equidae. ii. purification and cytological localization of a (g + c)-rich satellite dna from equus hemionus onager and cross-species hybridization to e. asinus chromosomes. | a (g + c)-rich satellite dna component (p = 1.716 g/ml) has been fractionated from the total dna of the iranian subspecies of the asiatic wild ass, equus hemionus onager, by successive dactinomycin-cscl and netropsin sulfate-cscl isopycnic gradients. complementary 3h-rna (crna) transcribed from the satellite dna hybridized predominantly to the centromeric and telomeric constitutive heterochromatic regions of onager chromosomes. these studies have suggested that satellite dna's with similar seque ... | 1983 | 6851669 |
| observations on fasciola hepatica in donkeys from morocco. | regular monthly examination of a total of 422 donkey livers revealed fasciola hepatica infection throughout most of the year, with an annual prevalence of 5.9% (range 0-20%). the monthly mean number of worms per animal varied from 0 to 6.4 (annual average 1.6). of the infected animals 40% had less than ten worms, 28% between ten and 40, 24% between 41 and 70, and 8% over 71. the maximum number of flukes recovered from a single animal was 87. there were two peaks of infection, one in july (from t ... | 1983 | 6882064 |

| maternal anti-fetal cytotoxic antibody responses of equids during pregnancy. | the maternal immunological response to the developing equine fetus was investigated in 69 pregnancies of various genotypes. in normal intraspecies horse pregnancy (n = 16), 94% of mares produced strong cytotoxic antibody responses to paternal histocompatibility antigens which were first detectable between 44 and 70 days after ovulation. in all other types of pregnancy examined (intraspecies donkey, n = 19; interspecies mule, n = 6; interspecies hinny, n = 2; extraspecies horse-in-donkey, n = 3; ... | 1982 | 6962872 |
| identification of salmonella typhi in faecal specimens by an antiserum-agar method. | an antiserum-agar technique was evaluated as a method for detecting salmonella typhi in faeces. thirty-one laboratory strains of s. typhi produced immunoprecipitate haloes during overnight growth on ss agar and blood-agar-base infusion agar (bab) containing donkey antiserum to a vaccine strain of s. typhi. other salmonella species sharing o serogroup antigens with s. typhi also produced haloes when streaked in pure culture on ss-antiserum agar but not on bab-antiserum agar. one hundred and forty ... | 1980 | 6991704 |
| comparative morphometry of the upper bronchial tree in six mammalian species. | the length, diameter, and angle of branching of all airways through the sixth level of branching below the trachea were measured on corrosion casts prepared from the lungs of two animals whose bronchial geometry has not previously been studied, namely the donkey and the rabbit. these measurements and morphometric data for the rat, hamster, dog, and human obtained from other sources were analyzed and compared. the case prepared from human lungs exhibited an airway geometry that was clearly distin ... | 1981 | 7013567 |
| studies of glucose metabolism in rhesus monkeys after venezuelan equine encephalitis virus infection. | previous studies have demonstrated a diabetogenic effect of venezuelan equine encephalitis (vee) virus in hamsters. a preliminary study was conducted in which five 2- to 3-year-old rhesus monkeys were infected with the virulent trinidad donkey strain of vee virus and their carbohydrate metabolism was studied over 10 months. all animals developed mild clinical illness (rhinorrhea, cough, fever), were viremic, and developed antibodies. as compared with the results of preinoculation intravenous glu ... | 1980 | 7014785 |
| clarification of the database concept. | our concern is that nursing databases be structured to improve the efficiency of decision-making in nursing. the selection of database management systems that are compatible with the computer resources in a majority of settings is important to methodology. to facilitate methodological development, we encourage the inclusion of information in the nursing literature that details the investments in personnel, equipment, and facilities required to develop computerized databases. in the current state ... | 1981 | 7015291 |
| a critical efficacy test of cambendazole in equids: the use of the geometric means to assess efficacy. | the anthelmintic efficacy of a 44.5% paste formulation of cambendazole was evaluated in a critical trial performed on 5 horses and a donkey. a dosage of 20 mg/kg showed reduction of mean parasite burdens as follows: strongylinae greater than 99%; cyathostominae 94%; immature and adult oxyuris equi 89 and greater than 99%; probstmayria vivipara greater than 99% and habronema muscae 97%. parascaris equorum and anoplocephala perfoliata were present in small numbers in individual animals only, and w ... | 1980 | 7017145 |
| characterization of antibodies to canine renal renin. studies of interspecies homology of renin using antibodies as probe. | antibodies raised to pure canine renal renin were used to probe homology of renin from other species. goat, rabbit, and mouse antibodies exhibited similar properties and were specific for renin as confirmed by immunodiffusion, immunoelectrophoresis, and selective inhibition of renin enzymatic activity. goat antibody also inhibited the enzymatic activities of rat, hog, and bovine renin. immunologic cross reactivity was further confirmed by direct binding and competition assays. goat anti-(canine ... | 1982 | 7040231 |
| comparison of two recently published algorithms for assessing the probability of adverse drug reactions. | 1 a simple valid and reliable method for estimating the probability of adverse drug reactions (adverse drug reactions probability scale, aps) has been recently described (naranjo et al., 1981a). 2 the results using aps were compared to those obtained with another more detailed algorithm (adverse reactions scoring system, ass) described by kramer et al. (1979). 3 sixty-three randomly selected adverse drug reactions (adrs) were rated by two observers, using aps and ass one year apart. the cases we ... | 1982 | 7059419 |
| a simple reverse-phase high pressure liquid chromatographic determination of conjugated bile acids in serum and bile using a novel radial compression separation system. | a new hplc method for analyzing conjugated bile acids in bile and especially in serum is presented. for separation of novel radial compression system with a 10-cm flexible-walled reverse phase column (rcm-100 module, waters ass.) packed with micro-bondapak c18 was used. without any laborious hydrolysis and derivatization steps, 10 conjugated bile acids are separated easily with a mobile phase of methanol/0.01 mol/1 kh2po4 (150:50, v/v; ph 6.0) in about 30 min, determined with a variable uv detec ... | 1982 | 7060274 |
| [the sequence of hemoglobins from an asiatic wild ass and a mountain zebra]. | the hemoglobins from an asiatic wild ass (equus hemionus kulan) and a mountain zebra (equus zebra) were analysed and the complete primary structure of the alpha and beta chains are described. the wild ass globin was separated in two alpha chains (alpha i and alpha ii) and one beta-chain by means of chromatography on cm-cellulose in 8m urea buffer at ph 6.5. the wild ass globin shows polymorphism in the alpha-chain like the horse hemoglobin. under the same chromatographic conditions only one alph ... | 1982 | 7061044 |
| fluorimetric determination of unsubstituted and 9(8)-o-acetylated sialic acids in erythrocyte membranes. | a method is described for all quantitative determination of free or glycosidically bound sialic acids with special reference to erythrocyte membranes. sialic acids, unsubstituted in their side chains, quantitatively yield formaldehyde after mild periodate oxidation (1 mm naio4, 15 min, 4 degrees c, in the dark). the formaldehyde is determined by the reaction with acetylacetone and ammonium acetate which leads to a sensitive fluorogen (f 410/510 nm). sialic acids o-acetylated at c-9 or c-8 are no ... | 1982 | 7076126 |
| [experimental model with the additional source of endogenous serotonin]. | the only experimental approach to the increase in the body serotonin level is a pharmacological one that has a number of shortcomings. the authors suggest an experimental model with additional source of endogenous serotonin (ass-model) which occurs after embryonal gastrointestinal tract transplantation beneath the skin of adult syngeneic mice. the developing transplants showed significant amounts of serotonin and serotonin-producing enterochromaffin cells. the ass-model provides long-term and se ... | 1982 | 7093493 |

| administration of antisomatotropin serum in diabetes mellitus. | the effect of antisomatotropin serum (ass), raised in horse against human growth hormone, on the carbohydrate metabolism of diabetics has been investigated. among the eight diabetic patients treated so far two had gh secreting pituitary adenoma, two insulin-dependent, and four others adult onset diabetes mellitus. the glucose tolerance curve improved in all but one patient. the effect lasted for two--four weeks. because of this short time of efficiency, the place of ass in the definite treatmen ... | 1981 | 7227326 |
| immunochemical determination of ldh-1. | an evaluation of a new immunochemical method for the heart isoenzyme of lactic dehydrogenase (ldh-1) is described. in this assay, a goat antibody against the m subunit of ldh is added to a patient's serum. donkey antigoat gamma globulin is then added, which precipitates the m-anti-m complex. ldh activity in the supernatant is thus a measure of the heart isoenzyme, since this isoenzyme is not precipitable by the anti-m antibody. assays for total ck, ck-mb, and total ldh, and ldh electrophoresis w ... | 1981 | 7234756 |
| anthelmintic efficiency of fenbendazole in equines. | a single oral dose of fenbendazole (fbz) at 10mg/kg body mass was given to 5 donkeys. a further 5 donkeys were dosed with a medicated lick (1 mg fbz/g lick) until the oral consumption was 10mg/kg body mass. in both trials fbz was highly effective against adults of the following genera: cyathostomum, cylicocyelus, cylicostephanus, cylicodontophorus, poteriostomum, cabellonema, craterostomum and triodontophorus; similarly high efficiency was obtained against the following species: habronema majus, ... | 1980 | 7241490 |
| sickled erythrocytes accelerate clotting in vitro: an effect of abnormal membrane lipid asymmetry. | a membrane lipid abnormality induced by sickling and found as a permanent alteration in the irreversibly sickled cell (isc) is the rearrangement of phosphatidyl ethanolamine (pe) and phosphatidyl serine (ps) from the inner to the exterior side of the lipid bilayer. since ps can provide a catalytic surface for the binding of blood coagulation factors and thus can exhibit procoagulant activity, we investigated the influence of oxy and deoxy reversibly sickled cells (rsc) ass well as isc on clottin ... | 1981 | 7248527 |
| dietary and hormonal regulation of urea cycle enzymes in rat liver. | when 6-week-old rats fed normal diet (22% protein) were transferred to 10 and 75% protein diet, the levels of urea cycle enzymes showed decreases and increases respectively. the activities expressed as units per gram wet weight of liver had not stabilized after 7 days on the new diet; the corresponding specific activities were closer to leveling off. four daily injections of cortisol raised cps, ass, and arginase. the percentage increases were greater on a 10 than on a 75% protein diet. adrenale ... | 1981 | 7250092 |
| [acetylsalicylic acid and food additive intolerance in urticaria, bronchial asthma and rhinopathy]. | adverse reactions (urticaria, angio-edema, bronchoconstriction, purpura) to aspirin (ass) and food-and-drug additives such as the yellow dye tartrazine and the preservative benzoate are observed all over the world. since the exact pathogenetic mechanisms of this condition is unknown, it is described as intolerance or pseudo-allergy and has been related to an imbalance of prostaglandin synthesis. among 620 patients with urticaria, bronchial asthma or chronic rhinitis, oral provocation tests with ... | 1981 | 7291963 |
| a survey of schoolchildren from a severe endemic goitre area in spain. | all the boys and girls between six and fourteen years old regularly attending school in three villages from an area in spain known ass las hurdes were studied with respect to thyroid size, body weight and height. casual urine samples were obtained for the determination of iodine and creatine concentrations. capillary blood was spotted on filter paper and used for the determination of thyroxine and thyrotropin by radioimmunoassay. the same survey was carried out in 354 school children from madrid ... | 1981 | 7302120 |
| vestibulo-thalamic projection to the anterior suprasylvian cortex of the cat. | suggestive evidence as to the site of a major thalamic relay of the vestibular projection to the anterior suprasylvian (ass) cortex in the cat has been obtained using the retrograde axonal transport of horseradish peroxidase. the thalamo-cortical neurons are located in several patches surrounding the posterior margins of the ventro-basal complex (vb). this area also was found to receive vestibulo-thalamic projections. it comprises different nuclear groups known to carry somatic, acoustic, visual ... | 1981 | 7308362 |
