| a comparative study of complement activation. | antisera to sheep erythrocytes (e) were raised in cattle, rabbits, mice, hamsters, guinea-pigs, ferrets, badgers, hedgehogs and fowls. cross activation of total haemolytic complement (thca) examined all combinations of sensitized sheep e and normal sera (including human); kinetic assays examined the lysis of e sensitized with rabbit antibodies. from the same species, all combinations of normal serum and xenogeneic e were used to measure total alternative pathway activity (tapa); tapa was also ac ... | 1985 | 4024450 |
| recent h1n1 viruses (a/ussr/90/77, a/fiji/15899/83, a/firenze/13/83) replicate poorly in ferret bronchial epithelium. brief report. | three recent wild-type h1n1 influenza virus isolates (a/ussr/90/77, a/fiji/15899/83 and a/firenze/13/83) replicated poorly in organ cultures of ferret bronchial tissue compared with the replication of an h3n2 wild-type virus (a/england/939/69). all four viruses replicated well in nasal turbinate tissue. examination of one h1n1 virus (a/ussr/90/77) in vivo showed heavy infection in the upper respiratory tract of ferrets but little in the lower respiratory tract. these results raise the possibilit ... | 1985 | 4026584 |
| a demonstration of two distinct geniculocortical projection patterns in albino ferrets. | the geniculocortical pathways of albino ferrets have been studied by injecting lectin bound horseradish peroxidase into the visual cortex and then studying the geniculate distribution of retrogradely labelled cells in the dorsal lateral geniculate nucleus. it has been shown that in ferrets, as in siamese cats, there are two quite distinct patterns of geniculocortical projection. one of the patterns seen in ferrets is comparable to the 'midwestern' pattern previously described in siamese cats, wh ... | 1985 | 4027667 |
| the organization of the lateral geniculate nucleus and of the geniculocortical pathway that develops without retinal afferents. | the fine structure and cortical connections of the dorsal lateral geniculate nucleus have been studied in postnatal (3.5-14-month-old) ferrets in which all retinal afferents had been removed prenatally at the time these fibers are first starting to invade the nucleus. the synaptic profiles in the mature nucleus show the cytological characteristics and arrangements that would remain if the retinal afferents were removed, with no significant compensatory ingrowth of foreign specific afferents. the ... | 1985 | 4027668 |
| brugia malayi: intravenous injection of microfilariae in ferrets as an experimental method for occult filariasis. | microfilaremia, immune responses, and pathology were compared in ferrets infected with 100 third-stage larvae of brugia malayi (subperiodic strain) or injected intravenously with 10(6) microfilariae. ferrets (mustela putorius furo) inoculated with third-stage larvae typically became patent during the third month after infection, with a mean patency of 123 +/- 25 (se) days. ferrets injected intravenously with microfilariae exhibited a relatively constant microfilaremia for 3-4 weeks and usually c ... | 1985 | 4029349 |
| patterns of muscarinic cholinergic binding in the striatum and their relation to dopamine islands and striosomes. | the distribution of muscarinic cholinergic binding sites in the striatum was studied in relation to the locations of other neurochemical markers in the developing rat, cat, ferret, and human. in addition, patterns of striatal muscarinic binding were studied in the adult cat. receptor binding autoradiography was carried out with tritiated propylbenzilylcholine mustard [( 3h]-prbcm), an irreversible muscarinic antagonist, and subsequent serial section analyses involved comparisons among patterns o ... | 1985 | 4031121 |
| the relationship between intracellular calcium and contraction in calcium-overloaded ferret papillary muscles. | the photoprotein aequorin was microinjected into cells on the surface of ferret papillary muscles. tension and aequorin light, a function of intracellular ca concentration ([ca2+]i), were monitored. the preparations were exposed to increased concentrations of extracellular ca ([ca2+]o). small increases in [ca2+]o led to the usual increase in both the systolic light signal and the developed tension. however, high [ca2+]o led to a fall in developed tension known as ca overload. this fall of tensio ... | 1985 | 4032294 |
| nervous control of mucin secretion into human bronchi. | pieces of ferret trachea and human bronchi were mounted in ussing chambers and given [35s]sulphate as a radiolabelled precursor of mucous glycoproteins (mucins). the output of 35s bound to macromolecules was studied as an index of mucin secretion. in the ferret trachea, electrical field stimulation increased the rate of mucin secretion. tetrodotoxin (10(-7) m or 10(-6) m) abolished this effect. pilocarpine (25 microm) stimulated the output of mucins from human bronchus. atropine (10(-5) m) aboli ... | 1985 | 4032317 |
| measurement and stoichiometry of bumetanide-sensitive (2na:1k:3cl) cotransport in ferret red cells. | the bumetanide-sensitive uptake of na+, k+(rb+) and cl- has been measured at 21 degrees c in ferret red cells treated with (sits + dids) to minimize anion flux via capnophorin (band 3). during the time course of the influx experiments tracer uptake was a first-order rate process. at normal levels of external na+ (150 mm) the bumetanide-sensitive uptake of k+ was dependent on cl- and represented almost all of the k+ uptake, the residual flux demonstrating linear concentration dependence. the upta ... | 1985 | 4032458 |
| identification by specific radioimmunoassay of two novel peptides derived from the c-terminus of porcine preprogastrin. | a radioimmunoassay has been developed using antibodies to a synthetic analogue of the c-terminal hexapeptide sequence of the porcine gastrin precursor. boiling water extracts of porcine antral mucosa contained immunoreactive material that diluted in parallel with standard peptide. concentrations of immunoreactivity were 5.5 +/- 0.8 nmol x g-1 (mean +/- s.e.m.) in antral mucosa and were closely similar to those of c-terminal heptadecapeptide gastrin immunoreactivity (5.0 +/- 0.6 nmol x g-1). appr ... | 1985 | 4035006 |

| coital stimuli controlling luteinizing hormone secretion and ovulation in the female ferret. | a series of experiments focused on the masculine coital behaviors controlling pituitary luteinizing hormone (lh) secretion and reflex ovulation in the estrous female ferret. an initial experiment investigated which coital stimuli from the male are required to induce ovulation. it was found that corpus luteum formation, which served as an index of ovulation, occurred in estrous female ferrets only if the male achieved a penile intromission. neck gripping, mounting, and pelvic thrusting behavior w ... | 1985 | 4039954 |
| effects of neonatal castration and testosterone treatment on sexual partner preference in the ferret. | groups of male and female ferrets were tested in a t maze to determine whether they preferred to approach and interact with a sexually active male or an estrous female. control male and female ferrets gonadectomized (gx) on postnatal day 35 and tested in adulthood while receiving no hormone or testosterone (t) displayed no significant preference. when given estradiol benzoate (eb), however, control males preferred stimulus females whereas control females preferred stimulus males. when tested in ... | 1985 | 4040251 |
| congenital malformations and variations in reproductive performance in the ferret: effects of maternal age, color and parity. | demographic data of ferrets from a commercial breeding colony were analyzed for the effects of maternal age, parity and strain on reproductive performance and the frequency of gross congenital abnormalities observed at parturition. litter size (mean +/- sem) was found to be greatest for young, primiparous females (10.3 +/- 0.2) and decreased with advancing maternal age and parity to a cohort mean of 8.1 +/- 0.1 for third parity females 16 months of age. age, parity or strain had no effect on 24- ... | 1985 | 4040588 |
| wheel-running during anoestrus and oestrus in the ferret. | wheel-running activity was studied in female ferrets (mustela putorius furo), during periods of anoestrus and oestrus, as well as after gonadectomy. during anoestrus wheel-running was restricted to the hours of illumination, but during oestrus extended into the dark period and was increased overall, with the number of wheel revolutions being doubled or trebled. in spayed females wheel-running was mostly limited to the light periods. | 1985 | 4041057 |

| role of extrinsic and intrinsic nerves in the relationship between intestinal motility and transmural potential difference in the anesthetized ferret. | in the anesthetized ferret jejunum, the role of extrinsic and intrinsic nerves in the relationship between intestinal motor activity and transmural potential difference (pd) was studied. in the vagally intact ferret and after sympathetic blockade, spontaneous bursts of jejunal motor activity were associated with fluctuations in transmural pd. both responses were abolished by vagotomy, atropine, and tetrodotoxin. prolonged electrical stimulation of the cervical vagus nerve induced a cyclical moti ... | 1985 | 4054520 |
| recurrent adenocarcinoma in a ferret. | a 4.5-year-old, neutered male ferret with a history of recurrent adenocarcinoma in the preputial region was given 2 radiation treatment courses designed to control the rapidly growing neoplasm. the tumor regressed completely after the first 3.5-week course of therapy. the ferret remained clinically disease-free for 4 months, at which time small masses were noticed in the inguinal area and the original tumor site. a second course of therapy was administered, which again resulted in complete clini ... | 1985 | 4055507 |
| attenuation of wild-type human influenza a virus by acquisition of the pa polymerase and matrix protein genes of influenza a/ann arbor/6/60 cold-adapted donor virus. | wild-type influenza a viruses can be attenuated for humans by the acquisition of genes from the a/ann arbor/6/60 cold-adapted (ca) donor virus. six-gene reassortants, that is, viruses containing the hemagglutinin and neuraminidase surface glycoprotein genes of the wild-type virus and the six remaining rna segments of the ca donor virus, are consistently attenuated for humans. during the production of a six-gene reassortant virus containing the surface glycoproteins of the a/washington/897/80 (h3 ... | 1985 | 4056002 |
| morphology, central projections, and dendritic field orientation of retinal ganglion cells in the ferret. | retinal ganglion cells were studied in pigmented ferrets that received small electrophoretic injections of horseradish peroxidase (hrp) into the dorsal lateral geniculate nucleus (lgnd) or optic tract. ferret retina contains a number of types of retinal ganglion cells of which the relative cell body sizes, dendritic field structures, and central projections correspond closely to those of retinal ganglion cell types in the cat. ferret retina contains about the same proportion of alphalike cells, ... | 1985 | 4056111 |
| gastric tone modifies the responses to extrinsic neural stimuli in the anaesthetized ferret. | to determine the relation between resting intragastric pressure and neuronally evoked motility responses, the stomach of the anaesthetized ferret was inflated with two volumes within the physiological range. vagal evoked contractions decreased as the resting pressure was increased. the decrease affected responses to high, but not low, intensity stimulation of the vagus. vagal evoked relaxation of the stomach increased as a linear function of resting pressure. atropine lowered the resting pressur ... | 1985 | 4057085 |

| effects of ryanodine on intracellular ca2+ transients in mammalian cardiac muscle. | we observed the effects of ryanodine on the aequorin luminescence, membrane potential, and contraction of canine cardiac purkinje fibers and ferret ventricular muscle. in canine purkinje fibers, ryanodine (10 nm to 1 microm) abolished the spontaneous spatiotemporal fluctuations in [ca2+] that occur as a result of ca2+-induced ca2+ release from the sarcoplasmic reticulum (sr) during exposure to low-na+ solutions. ryanodine strongly reduced the twitch and both components of the intracellular aequo ... | 1985 | 4065357 |
| brainstem connections of vagal afferent nerves in the ferret: an autoradiographic study. | using an autoradiographic technique the central connections of vagal afferent fibres in the ferret were studied. the results show that the principal site of termination is the ipsilateral nucleus of the tractus solitarius with smaller projections to the contralateral tractus nucleus, the dorsal motor nucleus of the vagus and the area postrema and subpostrema. the fibres cross the midline via the commissural nucleus of cajal. no evidence of vagal afferent fibres was found in the reticular formati ... | 1985 | 4066482 |
| the projection of the visual field onto the lateral geniculate nucleus of the ferret. | the projection of the visual field onto the dorsal lateral geniculate nucleus (lgn) of the ferret was mapped electrophysiologically. the nucleus contains a single orderly map of the contralateral visual hemifield. the upper visual field is represented dorsally and rostrally in the nucleus; central fields are found in the medial and caudal sections of the lgn; and peripheral fields are represented most laterally. the ipsilateral eye is represented in laminae a1 and c1 up to eccentricities of 20-3 ... | 1985 | 4067015 |
| anatomical organization of primary visual cortex (area 17) in the ferret. | the present report describes the intrinsic and extrinsic cortical connectivity of striate cortex (area 17) in the ferret. injections of horseradish peroxidase demonstrate periodic intrinsic connections over an extent of 2.5-3.0 mm, mainly in the supragranular layers but also occurring secondarily in layer 5. these connections have a stripelike configuration, with a center-to-center spacing of 0.5-0.7 mm. their laminar distribution and stripelike configuration resemble the pattern in the cat (gil ... | 1985 | 4067016 |
| distribution of ganglion cells in the retina of adult pigmented ferret. | the retinal ganglion cell distribution in adult pigmented ferret was mapped in nissl-stained retinas and in retinas back-filled with hrp after large bilateral injections of the enzyme into the brain. in common with other carnivores the ferret has an area of peak cell density equivalent to the area centralis and a prominent visual streak of high cell density extending horizontally across the retina. the maximum ganglion cell densities for the retinas were estimated to be 3500-5200 cells/mm2 in ni ... | 1985 | 4075115 |
| effect of exposure to 500 ppm sulfur dioxide on the lungs of the ferret. | male ferrets (mustela putorius furo) were exposed 3 h/day, 3 days/week for 12 weeks to 500 ppm so2. determinations were made of airway responsiveness by producing histamine dose-effect curves. lung tissues were fixed and studied by light and electron microscopy. epithelial cells of the trachea and bronchus were most affected. lesions observed included changes in ciliated cells, edema and cell infiltration. the most responsive animals to histamine were 2 from the exposed group. nasal discharge an ... | 1985 | 4081352 |
| vagal control of fluid transport, transmural potential difference, and motility in the ferret jejunum. | the role of the vagus nerve in the control of intestinal transport was investigated in the ferret jejunum in vivo. fluid transport was measured in an isolated 10-cm segment of jejunum by means of a single-pass perfusion technique with radioactive markers introduced into the perfusion fluid and the bloodstream of the animal. transmural potential difference (pd) and intraluminal pressure in the perfused jejunal loop were also monitored. vagal stimulation (20 hz, 20 v, and 0.5 ms for 1 min) resulte ... | 1985 | 4083347 |
