| development of the adult pelage in normal and hormone-injected spiny mice (acomys cahirinus). | the dorsal pelage of the adult egyptian spiny mouse (acomys cahirinus) consists primarily of coarse brittle spines which differ from those of the juvenile pelage. the development of the adult pelage in juvenile spiny mice was examined in normal and estradiol- or testosterone-injected animals. females complete the development of their adult pelage significantly faster than males. both estradiol and testosterone injections speed pelage development in males. testosterone causes a significant delay ... | 1981 | 7338723 |
| comparison of insulin secretion by the isolated perfused pancreas and perifused islets of the spiny mouse (acomys cahirinus). | the dynamics of glucose-stimulated insulin release were studied in the perfused pancreas and in isolated perifused islets of spiny mice. the pattern of insulin release induced by an increase of the glucose concentration from 2.8 mm to 16.7 mm was different in the two preparations. in the perfused pancreas there was an early insulin release contrasting with an absence of the early response in isolated islets. the later insulin release response (5 min to 30 min) was present and similar in both pre ... | 1981 | 7020305 |
| delayed or biphasic glucose-induced insulin secretion of pancreatic islets isolated from spiny mice (acomys cahirinus) : relation to age of animals. | the dynamics of insulin release from spiny mouse perifused pancreatic islets was investigated. in agreement with earlier studies we found no initial (0-10 min) insulin secretion in response to glucose in islets prepared from mice up to 35 weeks of age. the islets of animals older than 40 weeks, however, were characterized by greater insulin content, and a restored typical biphasic insulin secretion profile. the results suggest that immediate glucose response is modified by environmental or other ... | 1980 | 6989661 |

| glucose production by the perfused liver of the spiny mouse (acomys cahirinus): sensitivity to glucagon and insulin. | hepatic glucose production and its responses to glucagon and insulin were studied in perfused livers obtained from spiny mice (acomys cahirinus)--rodents characterized by normoglycemia, decreased glucose tolerance and decreased insulin secretion--and from swiss albino mice. the dose-response characteristics of glucagon-induced hepatic glucose output were similar in spiny and albino mice. however, maximally stimulated glucose production were significantly lower in the spiny mouse. furthermore, th ... | 1979 | 468520 |
| helminths of birds and mammals of israel. viii.- skrjabinocapillaria rodentium n. sp. (nematoda capillariidae) from gerbillid and murid rodents. | skrjabinocapillaria rodentium n.sp., found in the stomach of meriones crassus, gerbillus pyramidum, g. gerbillus, g. dasyurus and acomys cahirinus, is described. it differs from the other two species in the genus, s. bakeri and s. eubursata, mainly in being larger, having a larger number of stichocytes and having a cephalic influation in the female and not in the male. | 1979 | 485042 |
| the reproductive tract of the male spiny mouse (acomys cahirinus) and coagulation studies with other species. | the testes of the spiny mice showed asymmetry, the left being significantly heavier than the right (p = 0.025). histological studies indicated that spermatozoa were first present in the testes of animals 35--45 days of age but the maturation of the accessory glands, especially the lateral prostates and coagulating glands, occurred later. the highest fructose concentration in the adult was in the lateral prostates (126.97 +/- 22.23 mg fructose/100 g, n = 5) and coagulating glands (99.38 +/- 17.65 ... | 1979 | 513000 |

| significance of anomalous thermoregulation in the pre-diabetic spiny mouse (acomys cahirinus): oxygen consumption and temperature regulation. | in keeping with studies of other desert rodents, the potentially diabetic spiny mouse has been demonstrated to have a very low basal metabolic rate, disproportionate to its body weight. the maintenance of a lower body temperature in response to high environmental temperatures and a lack of increase in metabolic rate in response to cooling have also been demonstrated. assessments of "mechanical efficiency" have shown that spiny mice carry a potential selective advantage under fasting conditions. ... | 1977 | 603467 |
| significance of anomalous thermoregulation in the pre-diabetic spiny mouse (acomys cahirinus): cold tolerance: blood glucose and food consumption responses to environmental heat. | decreased cold tolerance, reduced food requirement for body weight maintenance and comparative resistance to the hypoglycaemic effect of fasting in high ambient temperatures have been demonstrated in the spiny mouse. these phenomena could be related to anomalous spiny mouse thermoregulation, a phenomenon which is common in desert rodents and is simulated by mutant and artificially diabetic rodent species. the data can be interpreted as showing evidence for a survival advantage of genotypes with ... | 1977 | 603468 |
| dietary-dependent cross-species similarities in maternal chemical cues. | acomys cahirinus pups preferred chemical cues from conspecific lactating females maintained on the maternal diet as compared to such cues from females fed an unfamiliar diet. likewise, chemical cues from maternal diet mus musculus were preferred over those from unfamiliar diet conspecific females. thus, the production of maternal chemical stimuli may be basically similar in acomys and mus, with maternal diet being more critical than genetically programmed species-specific characteristics in dete ... | 1977 | 11803674 |
| breeding and reproduction of fifteen wild rodents maintained as laboratory colonies. | data on reproduction and production were presented for laboratory colonies of microtus pennsylvanicus tananaensis, m oeconomus macfarlani, m o operarius, m mirurus, m abbreviatus, lemmus lemmus, l sibiricus trimucronatus, dicrostonyx stevensoni, clethrionomys rutilus, peromyscus maniculatus borealis, p m bairdii, baiomys taylori, calomys ducilla, c callosus, acomys cahirinus. litter size varied from 2.0 in a cahirinus to 5.5 in c callosus. infant (neonatal) and juvenile losses through the end of ... | 1976 | 775192 |
| proinsulin synthesis in islets of langerhans from spiny mice (acomys cahirinus). comparison with rats and mice. | proinsulin synthesis in response to different concentrations of glucose has been studied in islets of langerhans of acomys, rat and mouse. the response to increased glucose was small in acomys when compared with rat or mouse. the time course of the effect of glucose on proinsulin synthesis was also studied in sequential 15 min periods up to 60 min. with 5.5 mm glucose the rate of 3h-leucine incorporation for acomys islets were greater over the periods 15-30, 30-45 and 45-60 min after the additio ... | 1976 | 789163 |

| breeding and fertility of the egyptian spiny mouse, acomys cahirinus: effect of different environments. | 2 years experience with acomys in one laboratory confirmed the slow breeding rate found by other workers. on moving the animals to another laboratory there was a 2-5 fold increase in breeding rate. the most likely explanation of this change was the presence of copper in the drinking water at the 1st laboratory, due to the use of copper water pipes. the data relating to maintenance and breeding of acomys for 2 years at the 2nd laboratory were analyzed to provide a more representative picture of t ... | 1976 | 1256010 |

| the verification of neurones in the pancreas of spiny mice (acomys cahirinus). | the statement that up to now no neural elements could be identified in the islets of langerhans with the aid of electron microscopy led us to reinvestigate this question of innervation of the pancreas in spiny mice using light microscopy. single nerve cells as well as nerve fibre bundles could be found in the interlobular connective tissue of the pancreas. by constrast, we could observe neither nerve cells nor nerve fibres in the islets of langerhans. extrainsular neuroinsular complexes could no ... | 1976 | 773639 |
| sex-differences in the agonistic behavior of spiny-mice (acomys cahirinus). | observations of 8 groups each containing three adult spiny mice (acomys cahirinus) revealed that instances of chasing and physical displacement were quite common, while fighting and biting were rarely observed. the relationships between the most frequent behavioral categories were presented in a correlation matrix. in a second study, females tested in their home cages were dominant over males. in the males' home cages, however, no differences in the frequency of female vs. male aggression were o ... | 1976 | 944978 |

| [the evidence of biogenic amines with reinecke-salt as a new principle of evidence of substances in the ultrahistochemistry (author's transl)]. | reinecke-salt (ammonium tetracyanato diamine chromate) is known as amine precipitating reagens in applied chemistry. its amine precipitates can be demonstrated in electron micrographes. the amine reineckates are unable to diffuse and difficult to dissolve. depending from that they are localized in the cells. from our findings received in the boundary layer between adrenal cortex and adrenal medulla, we conclude that there are no non-specific precipitations with other cell components caused by re ... | 1975 | 813480 |
| retinal capillary basement membrane thickness in spiny mice (acomys cahirinus) with induced and spontaneous diabetes. | basement membrane thickness was measured in two groups of spiny mice (acomys cahirinus): one with spontaneous diabetes, the other with streptozotocin-induced diabetes. a statistical analysis of the morphometric results of the two groups showed a significant basement membrane thickening in the group with induced diabetes when compared to the spontaneously diabetic group. | 1975 | 124711 |

| an apparent abnormaltiy of the b-cell microtubular system in spiny mice (acomys cahirinus). | the pancreatic b-cell contains microtubules, which are thought to participate in the process of insulin release. in order to disclose a possible abnormaltiy of this b-cell microtubular system in animals with islet dysfunction, isolated islets from normal rats and mice, as well as from diabetic mutant mice (dbm mice) and from spiny mice (acomys cahirinus) were incubated in the presence of vincristine, which causes the precipitation of the microtubular protein into paracrystalline deposits. ultras ... | 1975 | 1095441 |
| defective early phase insulin release in perifused isolated pancreatic islets of spiny mice (acomys cahirinus). | in order to characterize pancreatic beta cell function in geneva bred spiny mice (acomys cahirinus), the dynamics of immunoreactive insulin release were examined during perifusion of pancreatic islets isolated from normoglycemic acomys. the initial insulin response of acomys was slow: no clear-cut early (1 to 10 min) peak of insulin release was observed when glucose in the perifusion medium was abruptly raised from 2.8 mm to concentrations as high as 56 mm. this was true for islets of either you ... | 1975 | 171800 |
| insulin secretion in the spiny mouse (acomys cahirinus). dose and time kinetic studies with glucose in vivo and in vitro. | plasma insulin responses to the intravenous injection of glucose in the doses of 0.5, 1.5, and 3.0 gm./kg. were compared in spiny mice (acomys cahirinus) and weight-matched swiss albino mice. the mean early (two-minute) plasma insulin response was significantly lower in acomys at all doses of glucose injected; whereas, at later times (5, 15, and 30 minutes), differences in plasma insulin concentrations in the two species of mice were smaller or nonexistent. plasma glucose clearance was significa ... | 1975 | 1104397 |
| ultrastructure of the oocytes of the egyptian sping mouse (acomys cahirinus). | the oocytes of types 2, 3, 4 and 5 follicles from the normal spiny mouse were examined withe the electron microsome. multiple juxtanuclear golgi bodies, mitochondria associated with flattened granular endoplasmic reticulum, and large nucleus are the main features of the type 2 follicle oocyte. the numbers of mitochondria and golgi apparati increase significantly at later stages. small mitochondrial aggregates lacking "intermitochondrial cement" are seen in the ooplasm of types 3, 4 and 5 follicl ... | 1975 | 1171638 |
