| photoperiodic stimulation of pubertal development in male deer mice: involvement of the circadian system. | pubertal development in prairie deer mice (peromyscus maniculatus bairdii) is accelerated by exposure of juveniles to a long-day photoperiod, and, conversely, retarded by exposure to short days. the purpose of the present study was to evaluate the possible involvement of the circadian system in the photoperiodic regulation of puberty. weanling males, previously housed on a short-day light cycle of 6l:18d, were subjected to a "resonance" protocol in which they received one of the following light ... | 1983 | 6850042 |
| isolation, purification, and characterization of deer mouse (peromyscus maniculatus bairdii) prolactin. | prolactin (prl) secreted by peromyscus maniculatus bairdii anterior pituitaries was purified by gel filtration on sephadex g-100 and ion-exchange chromatography on deae-cellulose. peromyscus prl (pmprl) eluted from sephadex g-100 with an elution-to-void volume ratio of 1.9 and at a salt concentration of 100 mm nacl on deae-cellulose. electrophoretic homogeneity of the hormone was demonstrated in several gel systems. on 7 1/2% alkaline polyacrylamide gels, pmprl migrated with an rf of 0.65. the m ... | 1983 | 6847207 |
| transmission studies with sarcocystis idahoensis of deer mice (peromyscus maniculatus) and gopher snakes (pituophis melanoleucus). | transmission studies with sarcocystis idahoensis of deer mice (peromyscus maniculatus) and gopher snakes (pituophis melanoleucus) were conducted to determine host specificity of various stages of the parasite. sporocysts were not passed by four dogs or four cats fed infected skeletal muscle from deer mice. seven white mice (mus musculus) and 34 white-footed mice (peromyscus leucopus) were negative for sarcocysts and liver meronts following oral inoculation with s. idahoensis sporocysts; however, ... | 1980 | 6776292 |

| immunological factors in peromyscus speciation. | reciprocal interspecific f1 hybrids of deermice (peromyscus maniculatus) and oldfield mice (p. polionotus) differ significantly and substantially in fetal and placental, as well as adult, size and weight. hybrid fetal mortality is associated with large conceptus size. skin grafts were exchanged between and within the two species to ascertain whether any relationship exists between mean graft retention time and body size of fetuses and adults. p. maniculatus skin grafted to p. polionotus rejected ... | 1982 | 6757375 |
| hepatic aldehyde dehydrogenase activity in peromyscus genetically deficient in alcohol dehydrogenase. | 1. hepatic aldehyde dehydrogenase (aldh) activity was measured in two strains of deer-mouse, peromyscus maniculatus. 2. there is no difference in the subcellular distribution of aldh activity in the two strains. animals of adhn/adhn genotype, lacking liver alcohol dehydrogenase (adh), had 90% of total aldh activity in the mitochondrial fraction compared to 94% for the adhf/adhf animals with normal adh activity. almost all of the remaining aldh activity was in the hepatic cytosol with less than 1 ... | 1982 | 6751681 |
| maximum oxygen consumption during exercise and cold exposure in deer mice, peromyscus maniculatus. | convenient methods were developed for measuring maximum oxygen consumption (vo2 max) in untrained small mammals during treadmill exercise and cold exposure. deer mice (peromyscus maniculatus) were run once, for 6-min periods at velocities exceeding maximal aerobic running speed, while instantaneous oxygen consumption was measured. the vo2 max during cold exposure was determined using high wind speeds to increase heat loss rates. during running, the kinetics of gas exchange were rapid and similar ... | 1984 | 6739991 |
| pathogenesis of trypanosoma brucei infection in deer mice (peromyscus maniculatus). light and electron microscopic study of testicular lesions. | the results of light and electron microscopic studies demonstrated that trypanosoma brucei infection produced marked testicular degeneration in deer mice (peromyscus maniculatus) with highly significant (p less than 0.001) decreases in testicular weight, seminiferous tubular diameter, and epithelial thickness. lesions in seminiferous tubules consisted of necrosis of spermatids, spermatocytes, and sometimes the spermatogonia. sertoli's cells had marked vacuolation and accumulation of phagocytic m ... | 1984 | 6730207 |
| pathogenesis of trypanosoma brucei infection in deer mice (peromyscus maniculatus). ultrastructural pathology of the spleen, liver, heart, and kidney. | trypanosoma brucei eatro 110 infection of the deer mice (peromyscus maniculatus) produced moderate to marked lesions in the spleen, liver, heart, and kidney seven to ten weeks after infection. splenic lesions consisted of marked splenomegaly, with infected spleens weighing 25.9 times control spleens. transmission electron microscopy of the sinuses and billroth's cords of the splenic red pulp demonstrated an increased cellularity with greater contact between cells due partly to proliferation of m ... | 1984 | 6730206 |
| effects of ingestion of chlorocholine chloride and cyclophosphamide on venezuelan equine encephalitis virus infections in deer mice (peromyscus maniculatus). | we investigated the effects of chlorocholine chloride (ccc), a plant growth regulator, and cyclophosphamide (cp), a known immunosuppressant, on the ability of deer mice (peromyscus maniculatus) to resist challenge with a sublethal dose of venezuelan equine encephalitis virus ( veev ). the toxicants were continuously delivered in low doses in the feed; cp at 20 mg/kg body wt/day and ccc at 1, 10, 20 or 40 mg/kg body wt/day. mice were inoculated with 3 x 10(4) plaque forming units (pfu) of veev af ... | 1984 | 6729837 |
| naloxone inhibition of stress-induced daily torpor. | peromyscus maniculatus, deermice , were induced into daily torpor by restricting food to one-half daily ration. intraperitoneal injection of naloxone (20 mg/kg) into mice habituated to daily ip injections of saline inhibited or modified the expression of daily torpor. in those individuals demonstrating long duration/deep bouts (greater than 300 min/body temperature 20 degrees c or below) naloxone administration resulted in 1) a significant decrease in the duration of torpor, 2) a significant ele ... | 1984 | 6727554 |
| influence of feeding chlorocholine chloride and glyphosine on selected immune parameters in deer mice, peromyscus maniculatus. | exposure to the plant growth regulators, chlorocholine chloride (ccc) and glyphosine (gps), resulted in significant immunomodulatory effects after feeding to deer mice (peromyscus maniculatus) for 28 days. cyclophosphamide (cp) and saline controls were included. both ccc and gps feeding levels were equivalent to 1, 10, 20, 40 and 80 mg/kg mouse/day. the parameters assessed were: spleen plaque forming cell (pfc) assays, hemolysin titers, white blood cell counts, bone marrow cellularity, hematocri ... | 1984 | 6710535 |
| latitude of origin influences photoperiodic control of reproduction of deer mice (peromyscus maniculatus). | three subspecies of peromyscus maniculatus originating from different latitudes were maintained from birth in light dark cycles that provided between 10 and 18 h of light per day. at 50 days of age, chihuahua, mexico mice (latitude of origin 27 degrees n) and south dakota, u.s.a. mice (44 degrees n) kept in the 10l:14d photoperiod had reduced gonadal and seminal vesicle weights and a lower spermatogenic index than corresponding mice kept in a 14l:10d photoperiod. some chihuahua and south dakota ... | 1983 | 6681991 |
| development and characterization of a homologous radioimmunoassay for deer mouse (peromyscus maniculatus bairdii) prolactin. | a highly specific and sensitive homologous radioimmunoassay has been developed for the secreted form of prolactin from the deer mouse peromyscus maniculatus bairdii. peromyscus serum and pituitary homogenates displayed parallel dilution response curves, and no cross reaction was seen with either mouse prolactin, mouse growth hormone or rat prolactin. the assay was sensitive to 25 picograms per tube and the intra- and inter-assay coefficients of variation were 5 and 3.6%, respectively. in additio ... | 1983 | 6645802 |
| pathogenesis of trypanosoma brucei infection in deer mice (peromyscus maniculatus). v. macrophage ultrastructure and function. | macrophage numbers increased in the spleen, liver, testes, heart, and kidney of deer mice infected for seven to ten weeks with trypanosoma brucei eatro 110. the macrophages were activated as indicated by their increased size and significant increases in numbers of cell organelles including profiles of rough endoplasmic reticulum (which also increased in length), mitochondria, primary and secondary lysosomes, bundles of golgi's apparatus, and free lysosomes compared to macrophages from control mi ... | 1983 | 6636469 |
| rhythms of barbiturate-induced sleep time in deermice entrained to non-twenty-four hour photocycles. | the present experiment examined whether entrainment to twenty-four hour days is advantageous for physiological and behavioral adaptations to a pharmacological challenge. adult, male deermice (peromyscus maniculatus) were injected with sodium pentobarbital at 8.5, 14.5, 20.5, 2.5 and again at 8.5 hr after light onset while entrained to a 24 hr day (light/dark (ld) 14:10). time to recover from anesthesia was recorded. subsequently, the dark phase of the ld cycle was reduced 15-20 min every 10 days ... | 1983 | 6635008 |
| hypothyroidism in reproductively inhibited prairie deer mice (peromyscus maniculatus bairdi) from laboratory populations. | several thyroid function parameters were compared between reproductively inhibited prairie deer mice of both sexes taken from laboratory populations and corresponding reproductively capable controls. the results of these experiments indicated the following: 1) prairie deer mice females had a statistically significant daily variation in mean serum thyroxine concentration and males displayed a similar trend; 2) total serum thyroxine and triiodothyronine were significantly lower in both male and fe ... | 1984 | 6518231 |
| influence of melatonin on pubertal development in male deer mice (peromyscus maniculatus). | the role of melatonin in pubertal development was assessed in male deer mice (peromyscus maniculatus bairdii) exposed to photoperiodic and social stimuli. exogenous melatonin retarded puberty in males reared in a long photoperiod, but was without effect in males reared in short days. melatonin did not retard pubertal development induced by exposure of short-day males to an adult female. these results suggest that pineal melatonin mediates photoperiodic, but not social, control of pubertal develo ... | 1984 | 6512757 |
| effect of transitional photoperiods on testicular development and puberty in male deer mice (peromyscus maniculatus). | in a series of five experiments, young male deer mice (peromyscus maniculatus bairdii) were exposed to photoperiods ranging in length from 3 to 19 h per 24-h period, as well as to constant light and constant darkness. reproductive organ growth as measured at 6 weeks of age was inhibited by less than or equal to 11.5 h of light. in males receiving 11.5-19 h of light, there was a quantitative increase in reproductive organ size as a function of photoperiod. rather than a 'critical' photoperiod par ... | 1984 | 6512756 |
| photosensitive stages in pubertal development of male deer mice (peromyscus maniculatus). | male deer mice (peromyscus maniculatus bairdii) were exposed to a long (15l:9d) or short (6l:18d) photoperiod during four stages of development. at 6 weeks of postnatal age degree of pubertal development was determined by measurement of testis and seminal vesicle weights and area of the androgen-dependent sebaceous gland. continuous exposure to a short photoperiod beginning before conception (i.e. mother kept in short days), at conception, or at birth markedly retarded pubertal development. init ... | 1984 | 6512755 |
| industrial lead contamination of an illinois wildlife refuge and indigenous small mammals. | deer mice (peromyscus maniculatus) were trapped from a sand prairie at various distances from an adjacent battery lead reclamation plant. analysis of liver, kidney, and bone for lead concentrations showed an increase of tissue lead concentrations over controls to a distance of approximately 400 m. soil and plant lead concentrations roughly correlated with the findings in deer mouse tissues. at higher tissue lead concentrations, acid-fast staining intranuclear inclusions within renal tubular epit ... | 1984 | 6511573 |
| atropine esterase status of laboratory mice. | fifty eight inbred strains of laboratory mice and two species of wild mice [mus castaneus (inbred) and peromyscus maniculatus bairdii (closed colony)] were tested for the presence of atropine esterase by the microhematocrit tube test of tucker and beattie. the results show clearly that laboratory mice do not have significant levels of atropine esterase as determined either by the microhematocrit tube test or by the agar plate test, and therefore that under these conditions atropine esterase is n ... | 1984 | 6482377 |
| kinetics of cytoplasmic aspartate aminotransferase from three genotypes of the deer mouse (peromyscus maniculatus). | three genotypic forms of the cytoplasmic enzyme, aspartate aminotransferase from the deer mouse (peromyscus maniculatus) were each analyzed kinetically after partial purification. kmapp and vmax for aspartate decreased in value as temperature changed from 37.9 to 15 degrees c for all three forms. for the aa genotype, the binding enthalpies were highest at 37.9 degrees c and lowest at 25 degrees c, while for the a'a' form, they were lowest at 37.9 degrees and highest at 25 degrees c. results for ... | 1984 | 6478801 |
| involvement of the circadian system in photoperiodic control of pubertal development in female deer mice, peromyscus maniculatus. | pubertal development in female deer mice, peromyscus maniculatus, was stimulated by exposure to light cycles of ld 16:8, ld 6:30 or ld 6:54, but not by exposure to cycles of ld 6:18 or ld 6:42. these results support the hypothesis that female deer mice use a circadian rhythm of responsiveness to light to measure photoperiodic time. | 1984 | 6468610 |
| evidence for heterosynaptic pairing of the inverted segment in pericentric inversion heterozygotes of the deer mouse (peromyscus maniculatus). | silver-stained pachytene cells of male deer mice, peromyscus maniculatus, which were heterozygous for a naturally occurring pericentric inversion of chromosome 6, were analyzed by light microscopy. the presence of the terminally positioned inversion, involving approximately 30% of the length of chromosome 6, was detected by g-banding. within the inversion, c-band-positive heterochromatin was restricted to the centromeric region. silver-staining of spermatocytes revealed the synaptonemal complexe ... | 1984 | 6467983 |
| effect of indomethacin on reproduction under laboratory and field conditions in deermice (peromyscus maniculatus). | the purpose of this investigation was to determine the long-term effect of enterically administered indomethacin (a prostaglandin synthetase inhibitor) on reproduction in peromyscus maniculatus (deermice) under both laboratory and field conditions. indomethacin-coated wheat (1 mg/kg wheat) was provided to the experimental animals in the laboratory and under field conditions ad libitum. rat chow was also provided to the animals in the laboratory. the laboratory data indicate that the number and s ... | 1983 | 6403066 |
| reservoirs of giardia spp. in southwestern alberta. | a survey of potential hosts of giardia spp. was carried out during 1982 and 1983 in the kananaskis valley and banff national park, alberta, canada. diagnosis was based mainly on fecal analysis but a few animals were examined at necropsy and scrapings from the small intestine analyzed. a total of 304 specimens was examined from humans (homo sapiens l.) and a variety of animal species. cysts and/or trophozoites of giardia were found in 10.5% of the specimens examined. positive samples were found f ... | 1984 | 6397598 |
| non-alcohol dehydrogenase-mediated metabolism of methylazoxymethanol in the deer mouse, peromyscus maniculatus. | the concept that alcohol dehydrogenase (adh) is involved in the metabolism of methylazoxymethanol (mam) was examined in a model consisting of two strains of the deer mouse, peromyscus maniculatus, one of which has a normal complement of the enzyme [adh(+)], and the other, which completely lacks it [adh(-)]. both the adh(+) and the adh(-) strains rapidly metabolized [14c]mam, administered in the form of the acetic acid ester, [14c] mamoac , to 14co2, and the rates and extents of metabolism were v ... | 1984 | 6372998 |
| normal testicular structure and reproductive function in deermice lacking retinol and alcohol dehydrogenase activity. | it was found that a strain of deermice (peromyscus maniculatus), which genetically lacks liver alcohol dehydrogenase activity also displays no such activity in the testis and is devoid of the enzyme activity that converts retinol to retinal, both in liver and in the testis; nevertheless, these animals exhibit normal reproduction and testicular histology. therefore, one must reconsider the theory that the testicular atrophy and aspermatogenesis commonly found in alcoholics is due, at least in par ... | 1984 | 6365975 |
| medroxyprogesterone, immunosuppression, and conceptus size in peromyscus. | effects of exogenous medroxyprogesterone acetate (mpa) on skin transplant retention and conceptus size were studied in the deer mouse, peromyscus maniculatus, and the oldfield mouse peromyscus polionotus. daily injections of 2 mg mpa significantly prolonged survival of allografts in p. maniculatus and transspecific grafts between p. maniculatus and p. polionotus. allografts were retained significantly longer than transspecific grafts (17.2 vs 12.4 days) on mpa-treated p. maniculatus. near-term f ... | 1983 | 6345716 |
| effects of experimental infection of the deer mouse (peromyscus maniculatus) with mouse hepatitis virus. | three deer mice (peromyscus maniculatus) given 10(4) tcid50 of mouse hepatitis virus -s intranasally all had significant serum neutralization titers to mouse hepatitis virus -s 3 weeks later. ten other deer mice were given 10(3) tcid50 of mouse hepatitis virus -3 intranasally and placed with sentinel laboratory mice (cf1, c3h/rv, and nu/nu) and uninoculated deer mice. one inoculated deer mouse died, but mouse hepatitis virus was not isolated. no other inoculated or uninoculated animals exhibited ... | 1982 | 6285078 |
| the ecology of colorado tick fever in rocky mountain national park in 1974. ii. infection in small mammals. | field studies of colorado tick fever (ctf) in small mammals in rocky mountain national park (rmnp) in 1974 established that eutamias minimus and spermophilus lateralis were the most important hosts for ctf virus and were the source of virus for immature stages of the tick vector, dermacentor andersoni. other species (peromyscus maniculatus, spermophilus richardsonii, eutamias umbrinus) are secondary hosts. the intensity of viral activity in rodents varied greatly from locality to locality. highe ... | 1981 | 6263122 |
| experimental colorado tick fever virus infection in colorado mammals. | one hundred and twenty-four small mammals of six species were inoculated with three strains of colorado tick fever (ctf) virus to define viremia and neutralizing (n) antibody responses. adult eutamias minimus and eutamias embrinus, and juvenile peromyscus maniculatus and spermophilus lateralis, were highly susceptible to development of viremic infection. adult s. lateralis and p. maniculatus were moderately susceptible (greater than or equal to 50% viremic). five sylvilagus nuttalli did not beco ... | 1981 | 6259958 |
| linkage relationships among eleven biochemical loci in peromyscus. | interspecific f1 hybrids of peromyscus maniculatus (deermice) and p. polionotus (oldfield mice) were backcrossed to p. maniculatus. backcross progeny were electrophoretically typed for 11 variant protein markers: albumin, transferrin, leucine aminopeptidase, amylase, 6-phosphogluconate dehydrogenase, nucleoside phosphorylase, dipeptidase, tripeptidase, glutamate oxaloacetate transaminase, alcohol dehydrogenase, and sorbitol dehydrogenase. genetic variation for each protein was attributed to a si ... | 1983 | 6200103 |
| serum acth and adrenal histology in reproductively inhibited male prairie deermice (peromyscus maniculatus bairdi). | exogenous acth will cause adrenal hypertrophy and gonad dysfunction in reproductively capable male deermice. the ultrastructure of the zona fasciculata of inhibited animals is substantially different from acth stimulated animals which suggests that acth alone does not produce the inhibition. although acth concentrations were variable, there was no clear demonstration that any differences existed between reproductively capable vs inhibited animals at the time when corticosterone is known to be el ... | 1984 | 6146448 |
| a possible role for the thyroid in reproductive inhibition in laboratory populations of the prairie deermouse (peromyscus maniculatus). | serum thyroxine concentrations were determined and found to be reduced in reproductively inhibited deermice selected from controlled growth laboratory populations. daily injections of 1 microgram thyroxine in reproductively inhibited male deermice were shown to significantly increase testis weight and the number of spermatids with acrosome formation. daily feeding of thyroxine to a controlled growth population promoted an increase in the mean weights of the reproductive organs of both sexes that ... | 1984 | 6142798 |

| chromosome variation in peromyscus: a new mechanism. | differences in total chromosome lengths between two karyotypically divergent groups of peromyscus maniculatus are taken as evidence for an deletion mechanism of chromosomal variation in the species. the differences may be due in part to variation in the amount of constitutive heterochromatin in the two karyotypes. | 2014 | 4113739 |
| effects of laryngeal denervation on ultrasound production and male sexual behavior in rodents. | adult male house mice (mus musculus) and deer mice (peromyscus maniculatus bairdi) were used to investigate the effects of partial denervation of the larynx on ultrasound production. in addition the masculine sexual behavior of vocalizing and muted males was assessed on tests with receptive females. for both species, unilateral transections of the inferior laryngeal nerve (iln) significantly reduced the proportion of males that emitted ultrasonic vocalizations. however, the inability to vocalize ... | 1985 | 4059379 |
| eimeria species (apicomplexa: eimeriidae) infecting peromyscus rodents in the southwestern united states and northern mexico with description of a new species. | of 198 deermice (peromyscus spp) collected from various localities in the southwestern united states and northern mexico, 106 (54%) had eimerian oocysts in their feces when examined. these included 50 of 106 (47%) peromyscus truei, 34 of 54 (63%) peromyscus maniculatus, 4 of 17 (24%) peromyscus leucopus, and 18 of 21 (86%) peromyscus eremicus. the following eimeria were identified from infected mice: eimeria arizonensis and eimeria langebarteli from p. truei; e. arizonensis, eimeria peromysci, a ... | 1985 | 4057004 |
| reproductive development in male deer mice exposed to aggressive behavior. | male deer mice (peromyscus maniculatus bairdii) were reared in a long photoperiod and housed individually from 3 weeks of age until they were killed 2, 4, or 6 weeks later. males that were exposed to aggressive females for 2 min, three times per week, were of normal body weight and healthy, but had smaller reproductive organs than did males exposed to a control treatment. reproductive development in male deer mice is responsive to at least two classes of social stimuli: pheromones and aggressive ... | 1985 | 4039275 |
| studies of pericopulatory pregnancy blockage and the gestation period in deer mice (peromyscus maniculatus). | it has previously been shown that female deer mice in cycling estrus that copulate with or are exposed to more than one male at the time of mating have a lower probability of delivering a litter than when mating with and being exposed to just one male. in the present research the effect of post-mating exposure to the bedding of a strange versus a familiar male was studied in females in postpartum estrus. in four experiments females in postpartum estrus were protected from pericopulatory pregnanc ... | 1985 | 4007797 |
| photoperiodic time measurement in the male deer mouse, peromyscus maniculatus. | weanling male deer mice, peromyscus maniculatus, were exposed for three weeks either to light-dark (ld) cycles with periods (t=l+d) ranging from t=23 (1l:22d) to t=25.16 (1l:24.16d) or to 24-h ld cycles with photoperiods ranging from 1 (1l:23d) to 19 (19l:5d) h. both the circadian locomotor activity rhythms and the response of the reproductive system to these ld cycles were assessed. the results demonstrate that the photoperiodic effectiveness of light depends on the phase of the light relative ... | 1985 | 4005352 |
| the mechanism of autosomal synapsis and the substaging of zygonema and pachynema from deer mouse spermatocytes. | surface-spread and silver-stained spermatocytes of peromyscus maniculatus and p. sitkensis were analyzed in order to develop criteria for the recognition of meiotic substages from early zygonema through early diplonema. the continuous sequence of changes in the morphology of the autosomal axes (lateral elements) of the synaptonemal complexes (sc), sex chromosome axes, and nucleoli enabled the recognition of three substages of zygonema and five of pachynema. the proposed system of subdivision is ... | 1986 | 3948599 |
| effects of intrahypothalamically administered norepinephrine, serotonin and bombesin on thermoregulation in the deermouse (peromyscus maniculatus). | norepinephrine, serotonin, and bombesin administered intrahypothalamically affected thermoregulation in the deermouse, peromyscus maniculatus. at a ta of 22 degrees c, doses of 3 micrograms and 6 micrograms of ne resulted in transient hypothermia (maximum drop of 1.6 +/- 1.0 degrees c and 4.3 +/- 2.3 degrees c, respectively). a 1.5 microgram dose of 5-ht induced a persistent hyperthermia (maximum increase of 1.8 +/- 0.8 degrees c) which persisted for more than 2 h. a 6 microgram dose of 5-ht did ... | 1986 | 3947967 |
| photic cues induce multiple neuroendocrine adjustments in testicular function. | neuroendocrine responses were evaluated in an outbred population of deer mice (peromyscus maniculatus nebrascensis) after exposure to an inhibitory photoperiod (8:16 light-dark) for 10 wk. deer mice were chosen as an animal model for this study because they are typical of naturally selected species that rely on environmental factors to signal the onset or cessation of annual reproductive effort. short photoperiods induced multiple neuroendocrine adjustments as judged by three types of spermatoge ... | 1986 | 3946637 |
| low p50 in deer mice native to high altitude. | whereas it is widely believed that animals native to high altitude show lower o2 partial pressures at 50% hemoglobin saturation (p50) than do related animals native to low altitude, that "fact" has not been well documented. consequently, p50 at ph 7.4, pco2(7.4), the co2 bohr effect, and the buffer slope (delta log pco2/delta ph) were determined via the mixing technique in peromyscus maniculatus native to a range of altitudes but acclimated to 340 or 3,800 m. pco2(7.4) and buffer slope were subs ... | 1985 | 3917990 |
| failure of 2-deoxy-d-glucose to stimulate feeding in deermice. | deermice (peromyscus maniculatus) did not increase their food intake above baseline following treatment with 2-deoxy-d-glucose (2dg, 500 or 1000 mg/kg). they did eat more following food deprivation or treatment with insulin at a high dose (100 u/kg). house mice (mus musculus) showed hyperphagia to 2dg, low dose of insulin (5 u/kg) and deprivation. | 1985 | 3898162 |
| chronic and acute trypanosomiasis in mice: a study by in vitro cloning of lymphohaematopoietic progenitors. | a semi-solid culture system was used to study the effects of trypanosome infection in two species of mice on the propagation of progenitor cells from the bone marrow and spleen. the deer mouse (peromyscus maniculatus) survived infection with trypanosoma (t.) equiperdum for more than 15 days. during the first 10 days there was inhibition of development of granulocyte-monocyte colonies from progenitor cells in the bone marrow. b-lymphocyte progenitors in the spleen showed increased activity, produ ... | 1985 | 3873680 |
