| electrical coupling between horizontal cell bodies in the tiger salamander retina. | we studied lateral interactions between horizontal cells in the tiger salamander retina in order to determine the underlying mode of synaptic transmission. pairs of cells, visually identified by inspection of the in vitro retinal slices, were impaled with two separate electrodes and the transmission between them was examined by injecting current into one cell while recording the resulting voltage response from the other soma. it was found that coupling between horizontal cells remained intact an ... | 1984 | 6087557 |
| the projection from the olfactory epithelium to the olfactory bulb in the salamander, ambystoma tigrinum. | odor quality may be represented as a "topographic" code of responses of receptor cells throughout the olfactory epithelium, with this code conveyed to the central nervous system by a topographic projection from the olfactory epithelium to the olfactory bulb. there is good evidence for topographic differences in odor-induced receptor cell activity in the tiger salamander but there is no evidence for a topographic epithelium-to-bulb projection in this species. in the present study 3h-leucine autor ... | 1984 | 6089611 |
| mechanisms of underwater hearing in larval and adult tiger salamanders ambystoma tigrinum. | 1. a standing wave tube apparatus was used to determine the biophysical basis of underwater hearing in ambystoma tigrinum. 2. a. tigrinum responds to the pressure component of underwater sound, and the mouth cavity appears responsible for transduction of sound pressure. 3. near-field displacements produced by pulsations of the air-filled mouth cavity apparently stimulate the inner ear. 4. salamander head preparations with no air-filled mouth cavity respond to the particle motion component of und ... | 1983 | 6132703 |
| distribution of monoamine oxidase activity in tissues of the urodeles ambystoma tigrinum (tiger salamander) and necturus maculosus (mudpuppy). | 1. monoamine oxidase (mao) activity was determined fluorometrically in tissues of adult mudpuppies, and pre- (young) and post- (adult) metamorphic tiger salamanders. 2. from responses to specific inhibitors it was determined that 95% activity was mao type a in all tissues. 3. in young salamanders mao activity was greater in brain and intestine of males than of females, and was considerably higher in kidney of both sexes and in intestine of males compared to adults. 4. mao activity was distribute ... | 1983 | 6132771 |
| localization of cholinesterase activity in the outer plexiform layer of the larval tiger salamander retina. | acetylcholinesterase activity, which may be indicative of cholinergic synapses, has been ultrastructurally localized in the outer plexiform layer of the larval tiger salamander retina using the cholinesterase staining method of karnovsky and roots. in the presence of the butyrylcholinesterase inhibitor, ethopropazine, precipitate is localized to discrete 'stain laminae' about 300 nm in their largest dimension and bounded by a 10 nm wide electron-lucent gap. stain laminae are predominantly found ... | 1984 | 6140990 |

| a sign-reversing pathway from rods to double and single cones in the retina of the tiger salamander. | signal transmission between rods and cones was studied by passing current into a rod and recording the voltage response in a nearby double or single cone and vice versa. two types of rod-cone interaction were found. between immediately adjacent rods and cones, passage of current into either receptor elicited in the other receptor a sustained voltage response of the same sign as the injected current. these signals were still seen in the presence of co2+, and are probably mediated by the electrica ... | 1983 | 6308225 |
| evidence for orthogonal arrays of particles in the plasma membranes of olfactory and vomeronasal sensory neurons of vertebrates. | plasma membranes of sensory neurons from the olfactory and vomeronasal neuroepithelia of the male rat and olfactory neuroepithelium of the tiger salamander (ambystoma tigrinum) have been examined, using the freeze-fracture technique, for the presence and morphology of orthogonal arrays of particles (oap). numerous oap were scattered on the p-face of plasma membranes of the dendrites and cell bodies from rat vomeronasal sensory neurons. the oap were 720 +/- 200 nm2 in area and they consisted of 4 ... | 1983 | 6311991 |
| a tiger mouse and relatives. variants caused by an activated transposable element? | in a laboratory-bred population of wild peruvian house mice, one male had an excessive rate of non-pairing of the x and y chromosomes. after crossing him with laboratory stock mice, a mouse of very unusual phenotype appeared from a yellow (aya) mother. he was yellow with black dorsal stripes; hence tiger. he was mated to many females, and inbred f2 and f3 generations were raised. there were no more tiger phenotypes, but his f1 contained an excess of black-and-tans over yellows, showing him to be ... | 1984 | 6323571 |
| effect of changes in intra- and extracellular sodium on the inward (anomalous) rectification in salamander photoreceptors. | solitary rod inner segments were obtained by enzymic dissociation of the tiger salamander retina. ih, an inward current activated by membrane hyperpolarization, was studied using the single-pipette voltage-clamp technique with patch pipettes. in order to investigate ih in isolation from voltage-dependent potassium and calcium currents, it was necessary to superfuse with a solution containing tea and cobalt. when the solution in the patch pipette contained 45 mm-kcl and 50 mm-nacl, the characteri ... | 1984 | 6323702 |
| a comparative study of potassium-induced relaxation in vascular smooth muscle of tiger salamanders and rats. | this study compares potassium-induced relaxation in vascular tissue of an amphibian (ambystoma tigrinum) and a mammal (rat). aortas (salamanders) and tail arteries (rats) were cut into helical strips for isometric force recording. after norepinephrine-induced contraction in potassium-free solution, arteries relaxed in response to added potassium (1-20 mmol/l). potassium-induced relaxation was greater in rat tail arteries than in salamander aortas. half-maximal relaxation occurred at a potassium ... | 1984 | 6331206 |
| pressure injection of 3',5'-cyclic gmp into solitary rod photoreceptors of the tiger salamander. | the outer segments of solitary rods of large neotenic ambystoma tigrinum were impaled with double-barrel micropipettes. one barrel was used to record membrane voltage and the other barrel was used both to pass voltage-clamp current and to pressure-inject cyclic gmp. injections of cyclic gmp induced inward currents in normal cells that were bathed in ringer's solution and studied at the dark, resting voltage. these cyclic gmp-induced currents reversed sign for voltages 25-40 mv more positive than ... | 1984 | 6331582 |
| temperature sensitivity of the renin-angiotensin system in ambystoma tigrinum. | the presence of a renin-angiotensin system was demonstrated in the poikilotherm ambystoma tigrinum, commonly called the tiger salamander. standard radioimmunoassay techniques were employed to measure the intrarenal renin activity (ira) and the plasma renin activity (pra) of a. tigrinum kept at either 5 or 20 degrees c. basal ira and pra values were not affected by the temperature at which the animals were maintained. intraperitoneal injection of the beta-adrenergic agonist isoproterenol, however ... | 1984 | 6372514 |

| location and function of voltage-sensitive conductances in retinal rods of the salamander, ambystoma tigrinum. | the functional role and spatial location of voltage-sensitive conductances that modify the light-evoked electrical signals were studied in retinal rods of the tiger salamander. an isolated rod was drawn into a suction electrode for recording membrane current and impaled with an intracellular electrode for recording membrane potential and passing current. a bright flash gave a rapid initial hyperpolarization that relaxed to a smaller plateau. simultaneously the dark current of the outer segment w ... | 1984 | 6481634 |
| clinical features therapy and epidemiology of tiger snake bite in dogs and cats. | snake bite was diagnosed in 125 dogs and 115 cats over 10 years. young sporting dogs and young cats were mainly affected. more dogs (48%) were seen in contact with tiger snakes than cats (7%). one hundred and four (84%) dogs and 89 (76%) cats were bitten in the warmer months of the year (october to march). as the incidence rose in september/october, dogs were bitten on days when the temperature was near 20 degrees c or over. the commonest presenting signs were dilated pupils and absences of pupi ... | 1984 | 6497804 |
| serum imipramine concentrations lower than plasma values. | in 10 patients, a comparison of serum and plasma concentrations of imipramine and desipramine, using b-d tiger-top and green-top tubes, respectively, showed the serum levels to be significantly lower. since such differences can influence evaluations of patients' dose schedules, it is important to ascertain the type of sample being used by the laboratory. | 1984 | 6501238 |

| regional differences in cell density and cell genesis in the olfactory epithelium of the salamander, ambystoma tigrinum. | the olfactory epithelium undergoes continuous regeneration. the present quantitative study uses tritiated thymidine autoradiography to investigate regional differences in the rate of olfactory epithelial cell genesis in the tiger salamander. there was a significant gradient in the incorporation of thymidine from the posterior to the anterior in the nasal cavity: the posterior epithelium underwent cell genesis much faster than the anterior. additionally, the posterior epithelium was thinner and c ... | 1984 | 6519235 |
| absorptance and spectral sensitivity measurements of rod photoreceptors of the tiger salamander, ambystoma tigrinum. | the spectral sensitivity of the extracellularly-recorded photoresponse of isolated rods of the tiger salamander, ambystoma tigrinum, was compared to the absorptance spectrum. both measurements were made with the same optical system on the same portion of each cell to avoid errors that could occur when the two kinds of measurement were made under different conditions. the relative spectral sensitivity and absorptance spectrum were found to be in excellent agreement between 450 and 700 nm. | 1984 | 6533990 |
| paragonimus heterotremus and other paragonimus spp. in thailand: pathogenesis, clinic and treatment. | six species of paragonimus have been reported in thailand: p. siamensis in cat, bandicoot and rat; p. bangkokensis in mongoose; p. harinasutai in cat and dog (experiment); p. macrochis in bandicoot and rat; p. westermani in tiger and p. heterotremus in cat, dog and man. it is interesting to note that in 1965 two immature p. heterotremus worms were recovered for the first time in man, namely in subcutaneous swellings in a boy; in 1981 nine mature p. heterotremus worms were expectorated after praz ... | 1984 | 6542391 |

| chronic encephalomyelitis caused by canine distemper virus in a bengal tiger. | a chronic progressive neurologic disease was observed and monitored for 18 months in a young, tamed bengal tiger. clinical, serologic, and neuropathologic evidence of canine distemper virus infection was seen. clinical signs included convulsions, myoclonus, and slowly progressive ataxia. marked increases in neutralizing antibodies against canine distemper virus were seen in the serum and cerebrospinal fluid. neuropathologic findings were nonsuppurative meningoencephalomyelitis, with perivascular ... | 1983 | 6685717 |
| involution of the auditory neuro-epithelium in a tiger (panthera tigris) and a jaguar (panthera onca). | numerical atrophy of the hair cells of the organ of corti of the inner ear in a 14-year-old tiger and a 17-year-old jaguar is described. the decrease in number of sensory hair cells is considered to represent physiological atrophy caused by the process of ageing. the findings are compared with previous observations on man, guinea-pigs, shrews, and bats. the development of the physiological involution of the hearing neuro-epithelium is discussed. | 1984 | 6699224 |
| topographic coding of odorant quality is maintained at different concentrations in the salamander olfactory epithelium. | in a recent study in the tiger salamander, ambystoma tigrinum, were demonstrated topographic patterns of responsivity across the olfactory epithelium which were characteristic for each odorant. the present study was initiated to investigate whether these patterns remain constant when odorant concentration is varied. odorant-induced electro- olfactograms were recorded from at least 12 sites on each epithelium. the odorants used were pinene, amyl acetate and propanol. each epithelium was tested wi ... | 1984 | 6722540 |
| comparison of the spatial and temporal expression of supernatant malate dehydrogenase in barbus hybrids (cypriniformes, teleostei). | the tissue specificity and ontogeny of supernatant malate dehydrogenase (s-mdh) are reported for the tiger barb, cherry barb, and their reciprocal hybrids. the tissue distribution of s-mdh isozymes in barbus is consistent with the patterns reported in other teleosts. the expression of the mdh-b locus is correlated with the initial muscle contractions of the developing embryos. it is suggested that the state of muscle cell differentiation may be the stimulus necessary for the expression of this l ... | 1984 | 6744821 |
| the mass of venom injected by two elapidae: the taipan (oxyuranus scutellatus) and the australian tiger snake (notechis scutatus). | using an enzyme immunoassay technique, a new method for measuring, in vivo, the mass of venom injected during snake bite, is presented. the venom injected into mice (as prey) and the venom left on the skin surface during bites by the two australian elapidae, the taipan (oxyuranus scutellatus) and the tiger snake (notechus scutatus) has been measured. venom delivery patterns vary significantly between these two species. in the case of the tiger snake (a total of 45 bites studied) the mean mass of ... | 1982 | 6753241 |
| sarcocystis and related organisms in australian wildlife: iii. sarcocystis murinotechis sp.n. life cycle in rats (rattus, pseudomys and mastocomys spp.) and tiger snakes (notechis ater). | sporocysts from tiger snakes (notechis ater) produced thick-walled sarcocysts in laboratory rats (rattus norvegicus). ultrastructurally these organisms were identical with sarcocysts found in native rats, but were different from sarcocystis singaporensis. sarocystis murinotechis sp.n. is proposed for this parasite of rodents and tiger snakes. when naturally-infected rats were fed to kittens (felis domestica), quolls (dasyurus viverrinus) and a masked owl (tyto novaehollandiae) no sporocysts were ... | 1980 | 6768904 |
| gonadotropin regimen for inducing ovarian activity in captive wild felids. | five species of felids (cheetah, north chinese leopard, tiger, lion, and puma) were serially injected with a source of follicle-stimulating hormone (fsh) to evaluate its effect on ovarian activity. animals were subjected to laparoscopy before and after gonadotropin treatment, and the number and appearance of mature ovarian follicles (mf), corpora hemorrhagica (ch), and corpora lutea (cl) were recorded and photographed. ovarian morphologic features, including mf, ch, and cl anatomy, were similar ... | 1982 | 6816775 |
| intracellular ph regulation in the renal proximal tubule of the salamander. na-h exchange. | using ph-sensitive microelectrodes to measure intracellular ph (phi) in isolated, perfused proximal tubules of the tiger salamander ambystoma tigrinum, we have found that when cells are acid-loaded by pretreatment with nh+4 in a nominally hco3--free ringer, phi spontaneously recovers with an exponential time course. this phi recovery, which is indicative of active (i.e., uphill) transport, is blocked by removal of na+ from both the luminal and basolateral (i.e., bath) solutions. re-addition of n ... | 1983 | 6833996 |
| intracellular ph regulation in the renal proximal tubule of the salamander. basolateral hco3- transport. | we have used ph-, na-, and cl-sensitive microelectrodes to study basolateral hco3- transport in isolated, perfused proximal tubules of the tiger salamander ambystoma tigrinum. in one series of experiments, we lowered basolateral ph (phb) from 7.5 to 6.8 by reducing [hco3-]b from 10 to 2 mm at a constant pco2. this reduction of phb and [hco3-]b causes a large (approximately 0.35), rapid fall in phi as well as a transient depolarization of the basolateral membrane. returning phb and [hco3-]b to no ... | 1983 | 6833997 |

| the peter pan and wendy syndrome: a marital dynamic. | a marital system is described which features an unfaithful and narcissistic husband, peter pan, and a long suffering and depressed wife, wendy. the dynamics of their individual adjustments are examined as well as the symbiotic nature of the dyadic relationship. other characters take their parts--tinker bell, tiger lily, and little lost boys. peter's infidelities belie a firm attachment to his wendy/mother whilst she depends upon him for protection from forbidden impulses. | 1982 | 6957178 |
| complete amino-acid sequence of a non-neurotoxic, non-enzymatic phospholipase a2 homolog from the venom of the australian tiger snake notechis scutatus scutatus. | the complete amino acid sequence of notechis ii-1, a non-neurotoxic, non-enzymatic phospholipase a2 homolog from the venom of the australian tiger snake notechis s. scutatus has been determined. the protein consists of a single chain of 119 amino acids. the main fragmentation of the reduced and s-carboxymethylated derivative was accomplished by cleavage with staphylococcus aureus v8 protease. tryptic peptides were used to align and complete the sequence, which was determined mainly by automated ... | 1980 | 7007039 |
| allozyme heterozygosity and growth in the tiger salamander, ambystoma tigrinum. | statistically significant, positive correlations were found between individual heterozygosity at seven protein polymorphisms and size in five natural populations of tiger salamanders. when these same populations were sampled later in the same year, the positive associations between heterozygosity and size were no longer evident. a pair mating was conducted in the laboratory, and offspring were distributed randomly to four replicate populations maintained in the laboratory. in two to these four r ... | 2006 | 7108182 |
| spatial pattern of sensory cell terminals in the olfactory sac of the tiger salamander. i. a scanning electron microscope study. | the olfactory sac of adult tiger salamanders (ambystoma tigrinum) was assessed by scanning electron microscopy and the hitherto unknown variety of the olfactory sac cells has been documented. regional differences in respect to the composition of the apical epithelial surface border in the olfactory sac have been recorded. transitions between the olfactory epithelium proper and epithelia with different surface structures have been described. it has been shown that both the roof and the floor of t ... | 1982 | 7130039 |
| the properties of single cones isolated from the tiger salamander retina. | 1. the properties of isolated single cones were studied using the voltage-clamp technique, with two micro-electrodes inserted under visual control.2. single cones had input resistances, when impaled with two electrodes, of up to 270 momega. this is probably lower than the true membrane resistance, because of damage by the impaling electrodes. the cone capacitance was about 85 pf.3. the cone membrane contains a time-dependent current, i(b), controlled by voltage, and a separate photosensitive cur ... | 1982 | 7131315 |
| envenomation by a king island tiger snake (notechis ater humphreysi). | a venomous king island tiger snake (notechis ater humphreysi)bit a herpetologist on the hand on the forty-eight floor of a sydney city building. prompt first-aid treatment, comprising the application of a wide constrictive bandage the length of the limb, combined with immobilisation, delayed central movement of the venom until resuscitative care and antivenom were available. the patient had received tiger-snake antivenom 16 years previously, and also suffered from atopic eczema. administration o ... | 1982 | 7132866 |
| heterogeneity in the distal nephron of the salamander (ambystoma tigrinum): a correlated structure function study of isolated tubule segments. | studies on isolated perfused tubules of the tiger salamander (ambystoma tigrinum) have shown that the distal nephron is heterogeneous with respect to function (stoner, 1977). in this study, the initial portion of the distal tubule (diluting segment) exhibited a voltage, positive in the lumen, and a net absorption of chloride. since the chloride was transported against an electro-chemical gradient, its transport was active. more distad, the junctional segment exhibited a lumen-negative voltage an ... | 1982 | 7149280 |
| voltage-activated and calcium-activated currents studied in solitary rod inner segments from the salamander retina. | 1. solitary rod inner segments were obtained by enzymatic dissociation of the tiger salamander (ambystoma tigrinum) retina. their membrane currents were studied with the single-pipette voltage-clamp technique. individual currents were isolated with the aid of pharmacological agents.2. extracellular caesium blocked a current activated by hyperpolarization from -30 mv. changing external sodium and potassium concentrations altered the value of the reversal potential in a manner consistent with the ... | 1982 | 7153904 |
| inflammatory myopathy in a captive bengal tiger. | a 9-year-old female bengal tiger (panthera tigris tigris) was presented with a history of progressive hindlimb weakness and muscle atrophy. serum muscle enzyme activities were high, and electrophysiologic examination suggested an underlying myopathic process. muscle biopsy revealed an inflammatory myopathy, with multifocal collections of inflammatory cells. there was severe muscle fiber necrosis with some evidence of regeneration. the cellular infiltrate consisted predominantly of macrophages, w ... | 1982 | 7174435 |

| a study of the major australian snake venoms in the monkey (macaca fascicularis). ii. myolytic and haematological effects of venoms. | rhesus monkeys were kept in a restraining apparatus and while conscious injected with the venoms of a range of australian snakes. although the action of restraining itself caused an elevation of the animals' plasma creatine kinase (c.k.), the rise was up to 5 times greater in envenomed monkeys. the venoms of the tiger snake, mulga, beaked sea snake, rough-scaled, copperhead and red-bellied snakes were all powerfully myolytic, and those of the taipan and small-eyed snake less so. no myolytic acti ... | 1981 | 7335377 |
| rod and cone signals in the horizontal cells of the tiger salamander retina. | 1. intracellular recordings of horizontal cell responses to monochromatic lights of various wave-lengths and intensities were made in the retina of the larval tiger salamander in order to determine the contributions of rod and cone activities to horizontal cell responses. 2. under conditions of extensive dark adaptation, and with dim light stimulation, the horizontal cell responses reflected mainly rod activity. in the light-adapted state or at high light intensities the cone contribution was do ... | 1980 | 7359420 |

| trypsin fails as australian snake bite cure. | trypsin has been claimed a new and effective treatment for venomous snake bite. we found that significant inactivation of snake venom lethal potency occurred in vitro when trypsin was incubated with venom and subsequently injected into mice. premixing of tiger snake venom (tsv) and trypsin just before injection did not significantly increase the survival rate of mice over that of controls injected with tsv alone. trypsin injected 10 to 30 minutes after tsv injection did not increase the survival ... | 1980 | 7453612 |
| the multi-ion nature of the cgmp-gated channel from vertebrate rods. | 1. native cgmp-gated channels were studied in rod outer segments of the larval tiger salamander, ambystoma tigrinum. the alpha-subunit of the cgmp-gated channel, here referred to as the wild type (wt), and mutant channels were heterologously expressed in xenopus laevis oocytes. these channels were studied in excised membrane patches in the inside-out configuration and were activated by the addition of 100 or 500 microm cgmp. the current carried by monovalent cations was measured under voltage-cl ... | 1995 | 7473247 |

| a tiger behind many doors: multiple genetic pathways to malignant glioma. | malignant gliomas are the most common primary human brain tumours, but their classification remains controversial and effective therapies remain elusive. as a result, malignant gliomas have come under intense scientific scrutiny, in the hope of elucidating the molecular basis of glial tumourigenesis. these studies have yielded insights into the genetic events that underlie glioma formation and progression, and have shown multiple distinct genetic pathways that lead to the common malignant endpoi ... | 1995 | 7482768 |
| [precocious parkinson's disease associated with "eye-of-the-tiger" type pallidal lesions]. | we report the case of a 56-years-old woman patient, born to unrelated parents, who since 26-years-old gradually developed bradykinesia, rigidity, tremor of both hands, and speech and gait difficulties. her past history was unremarkable. there was no family history of neurologic disease. she was admitted to our hospital at age 39 and at that time she presented a full parkinsonian syndrome. the following tests were normal or negative: routine blood studies, serum copper, ceruloplasmin and cerebros ... | 1995 | 7487542 |

| separating population structure from population history: a cladistic analysis of the geographical distribution of mitochondrial dna haplotypes in the tiger salamander, ambystoma tigrinum. | nonrandom associations of alleles or haplotypes with geographical location can arise from restricted gene flow, historical events (fragmentation, range expansion, colonization), or any mixture of these factors. in this paper, we show how a nested cladistic analysis of geographical distances can be used to test the null hypothesis of no geographical association of haplotypes, test the hypothesis that significant associations are due to restricted gene flow, and identify patterns of significant as ... | 1995 | 7498753 |
| toxic effects of linear alkylbenzene sulfonate on the tiger prawn, penaeus monodon. | the toxic effects of linear alkybenzene sulfonate (las) on the larvae and juveniles of tiger prawn penaeus monodon were tested. the 24-hr lc50 values of las were 0.06, 0.10, and 3.11 ppm for the zoea 2nd substage, mysis 2nd substage (m2), and postlarva 12th substage (pl12) of the tiger prawn, respectively. the 48-hr lc50 values of las were 0.07, 1.03, and 4.36 ppm for m2, pl12, and postlarva 15th substage of the tiger prawn, respectively. the hepatopancreatic glutathione (gsh) in juvenile tiger ... | 1993 | 7507819 |
| localization of substance p and gaba in retinotectal ganglion cells of the larval tiger salamander. | the present study was performed as part of a systematic examination of the transmitter specificity of neuronal populations in the larval tiger salamander retina. backfill-labeling of ganglion cells from the optic tectum was combined with double-label immunofluorescence histochemistry to determine if substance p and gaba are localized to ganglion cell populations in the tiger salamander retina. the triple-label analysis revealed the presence of substance p- and gaba-ganglion cells in both central ... | 2013 | 7516178 |
| gating, selectivity and blockage of single channels activated by cyclic gmp in retinal rods of the tiger salamander. | 1. patches in the inside-out configuration were excised from the membrane of outer and inner segments of the larval tiger salamander, ambystoma tigrinum. the current flowing through single channels opened by cyclic gmp was studied with the voltage clamp technique. 2. amplitude histograms of current recordings from patches containing only one flickering channel, excised from the inner segment and in the presence of 100 microm cyclic gmp, could be fitted by a theoretical scheme in which the single ... | 1994 | 7516427 |
| meniscal ossification. ii. the normal pattern in the tiger knee. | examination of knee menisci of bengal tigers revealed ossicles within the cartilaginous anterior horn of each medial meniscus. this ossification was not evident in the neonatal animal, but was present in animals aged 20 months or older. the ossicle appeared prior to the completion of skeletal maturation at the knee, and was composed of normal remodeling trabecular bone. while most animals had a single, variably sized ossicle, multiple ossicles also occurred. the meniscal cartilage apposed to the ... | 1994 | 7517071 |
| modulation of ion channels in rod photoreceptors by nitric oxide. | subcellular compartments in the outer retina of the larval tiger salamander were identified as likely sites of production of nitric oxide (no), a recently recognized intercellular messenger. nadph diaphorase histochemistry and no synthase immunocytochemistry labeled photoreceptor ellipsoids and the distal regions of bipolar and glial cells apposing photoreceptor inner segments, suggesting a role for no in visual processing in the outer retina. we investigated the actions of no on several rod pho ... | 1994 | 7520253 |
| nbqx suppresses inhibitory glycine currents in retinal ganglion cells. | the quinoxaline nbqx (2,3-dihydroxy-6-nitro-7-sulfamoylbenzo (f) quinoxaline) is a potent non-nmda receptor antagonist, which appears to be relatively free of antagonistic action at the glycine binding site of the nmda receptor. however, we report here that at 50 microm, nbqx significantly attenuated the inhibitory currents induced by the exogenous application of 100 microm glycine as observed using whole-cell recordings from ganglion cells in a slice preparation of the tiger salamander retina. ... | 1994 | 7529589 |
