| the arabs and the science of population distribution. | before the establishment of demography as a scientific discipline, arab writers had developed and utilized demographic principles in their scientific writings about geography. early arab advances in demographic thought, especially in regard to population distribution, were discussed. (all dates were given as anno hegira (ah), i,e., the dates accord with the muslim calendar in which the 1st year coincides with mohammed's flight from mecca in 622). as early as the 2nd century hegira, a number of ... | 1982 | 12266315 |
| a training tool in group dynamics. the camel-trading incident. | the objective of this training tool in group dynamics is to have the participants' experience and identify barriers to the accomplishment of group tasks and to give the trainer an opportunity to observe interaction within a particular group of participants. this exercise works best for groups which have been together long enough to establish mutual trust. there can be 10 to 20 participants and one should allow 1 1/2 to 2 hours. the materials required are pieces of paper to represent currency, ... | 1982 | 12312111 |
| corticotropin and beta-endorphin-like materials are native to unicellular organisms. | multiple molecular forms of immunoreactive corticotropin (acth) and beta-endorphin were present in extracts of a unicellular eukaryote (tetrahymena pyriformis). one form of immunoreactive acth reacted similarly with two different acth antisera (one specific for the 11-24 sequence and the other with determinants within sequences 1-14 and 17-39) and migrated with synthetic hacth-(1-39) in a gel filtration system. this form also exhibited acth bioactivity in a dispersed rat adrenal cell bioassay sy ... | 1982 | 16593172 |
| a simple classification of different types of trypanosomiasis occurring in four camel herds in selected areas of kenya. | camels from herds in four different areas of kenya were sampled at regular intervals over periods of 9-15 months and examined for the presence of trypanosomiasis. five hundred and eight camels divided into three age categories were studied. trypanosomiasis caused by t. evansi, t. brucei and t. congolense was shown to be present in varying degrees in all the herds. camels were divided into 5 types according to mortality, the presence or absence of circulating trypanosomes and antibody, and the pr ... | 1983 | 6141655 |
| the prenatal development of hair follicles and hair in the one-humped camel (camelus dromedarius). | the development of the hair follicles started in the prescapular region of crl 15 cm-fetuses as follicular plugs. at crl 31 cm, they became cylindrical cell cords. in the crl 45 cm-fetus two types of growing follicles, primary and secondary ones, could be differentiated, while the tertiary follicles were still follicular plugs. the follicles formed groups, and the primary follicles attained their complete structure at crl 79 cm, while the secondary follicles at crl 83 cm. the tertiary follicles ... | 1983 | 6201017 |
| camelpox and its risk to the human population. | camelpox is mainly of economic importance due to its relatively high mortality, loss of condition and fall in milk production and weight of affected camels. clinically, two distinct types can be distinguished: the severe, generalized form, which appeared more frequently among young animals and the milder, localized form encountered more often in older camels. a higher incidence of illness and a twice higher case fatality rate were observed among male camels. deaths occurred in 30% of the observe ... | 1983 | 6304186 |
| the effect of naloxone on vasopressin release from rat neurohypophysis incubated in vitro. | rat posterior pituitaries were superfused in vitro and stimulated electrically. the concentrations of vasopressin in the superfusion medium were determined by radioimmunoassay. when the pulses were applied in 10 sec trains with 10 sec intervals, vasopressin release per pulse increased progressively over the frequency range of 3-12 pulses/sec applied within the trains. the release was blocked by addition of tetrodotoxin or by removal of calcium ions from the superfusion medium. the opiate antagon ... | 1983 | 6620188 |
| camel production in kenya and its constraints. i. productivity. | initial results from an ongoing study of the productivity in three herds of camels are presented. the effects of different management systems, traditional nomadic vs. commercial ranching, on growth, fertility and early mortality are described as well as the differences in the genetic potential of two types of indigenous camels. | 1983 | 6623648 |
| camel production in kenya and its constraints. ii. tick infestation. | the tick loads and tick species infesting an experimental herd, a rendille pastoralists' herd and two ranch herds of camels, in four different areas of kenya are described. the tick species most commonly observed were hyalomma rufipes, hyalomma dromedarii and rhipicephalus pulchellus. | 1983 | 6623649 |
| investigation by photochemically-induced dynamic nuclear polarization and nuclear overhauser enhancement 1h-nmr of the interaction between beta-endorphin and phospholipid micelles. | the photochemically-induced dynamic nuclear polarization technique has been used to investigate the access of a photoexcited flavin dye to tyrosyl and histidyl residues in [met]enkephalin and human and camel beta-endorphins, both alone and in the presence of n-dodecylphosphorylcholine micelles. the results indicate that the mode of binding of tyr-1, but not of residue 27, is similar in the two endorphins and differs from that of tyr-1 in [met]enkephalin. in human beta-endorphin, accessibility an ... | 1983 | 6307694 |
| studies on the sero-epidemiology of endemic diseases in libya. i. echinococcosis in libya. | in libya traditional animal husbandry and the practice of domestic slaughter of food animals contribute to the maintenance of the echinococcus cycle. the cost of echinococcosis is high and may significantly affect the national economy. this study, employing the elisa test, has indicated an approximately 10% infection rate in children and young adults from the environs of benghazi, no difference being apparent between rural and urban dwellers. the prevalence of the infection should be determined ... | 1983 | 6639185 |
| the pathogenesis of experimental haemonchus longistipes infection in goats. | goats are highly susceptible to haemonchus longistipes and could therefore serve as an inexpensive model to study camel haemonchosis. the course of the disease in goats is similar to that in camels and to h. contortus infection in sheep and goats. unlike the age-dependency of camel haemonchosis, however, the severity of h. longistipes infection in goats is dose-dependent and varies from mild to hyperacute. | 1983 | 6643762 |
| the foetal thyroid of the dromedary: its relation to body weight and dimensions and to the weight of the dam's thyroid. | growth and iodine content of the thyroid glands in relation to body weight, length [total (bcvrt), crown-rump (cr), and curved crown-rump (cvr)], chest circumference (cc), and age were investigated in 83 camel foetuses from 70 to 355 days of gestation (mean gestation length 390 days). weight and iodine content of the dam's thyroid were also studied. highly significant (p less than 0.01) correlations of 0.883, 0.797, 0.798, 0.792, and 0.813 were obtained between foetal thyroid weights on the one ... | 1983 | 6649409 |
| the prenatal development of the skin in the one-humped camel (camelus dromedarius). | the epidermis of the camel started its development as a single layer of cuboical cells. the second layer occurred at the fetal stage of c rl 5 cm and the intermediate cell layer at the c rl 10 cm-stage. in the c rl 83 cm - fetus the epidermis is differentiated into the stratum basale, stratum spinosum, stratum granulosum and stratum corneum. in the dermis the collagenic and reticular fibres were observed in the 2 cm - fetus, and the elastic ones at the c rl 20 cm - stage. | 1983 | 6649775 |
| phenotypic variations in blood and milk of the somali camel. | 132 blood samples and 54 milk samples obtained from somali camel were analysed for red blood cell antigens with the cattle reagents and for hb, ca, x proteins, tf, alb, am, sod, alpha-la, beta-lg and casein systems respectively. positive lytic reactions were obtained with the anti-b, -q, -q', -w, -f1 and -j reagents. no biochemical polymorphism was observed except for hb, x protein and beta-lg systems. | 1983 | 6660598 |
| electroacupuncture analgesia blocked by microinjection of anti-beta-endorphin antiserum into periaqueductal gray of the rabbit. | the possible role of beta-endorphin (beta-ep) in mediating the analgesic effect elicited by electroacupuncture (ea) was assessed by injecting antiserum against beta-ep into the periaqueductal gray (pag) of the rabbit. two antisera (ho and ua) were raised in rabbits against human beta-ep, each of which recognized human, porcine, bovine, ovine, camel and rat beta-ep, the only difference being that ho recognized rabbit beta-ep while ua did not. the effect of ea analgesia was found to be seriously a ... | 1983 | 6305863 |
| isoelectrofocusing on flat bed for determining and separating beta-endorphin. | camel synthetic beta-endorphin focused in three bands by isoelectrofocusing on 1 mm polyacrylamide thin gel. all the bands have opioid activity, measured on guinea pig ileum, and radioimmunologically react with beta-endorphin antiserum. since beta-endorphin from rat pituitary gland, particularly from the neurointermediate lobe, also focused in several bands, we hypothesized that the camel peptide occurs in different conformations. a quick, simple technique based on histoelectrofocusing is propos ... | 1983 | 6319851 |

| the development of the sweat and sebaceous glands in the skin of the one-humped camel (camelus dromedarius). | the sweat gland primordium appeared as a solid bud from the ental side of the epithelial cords of the growing hair follicles in the crl 36 cm-fetus from the primary hair follicles and in the crl 64 cm-fetus from the secondary ones. in the crl 68 cm-fetus the glands were tubular with a slight curving of their lower third, which became convoluted at the crl 83 cm-stage. at the latter age, clear myoepithelial cells were observed in the secretory portion as also in the duct. the buds of the sebaceou ... | 1983 | 6201018 |
| studies on the histogenesis of the tunica mucosa of the small and large intestines of the camel (camelus dromedarius). ii. histogenesis of the colonic mucosa. | the colon is at first a simple tube, and its mucosa has a smooth luminal surface, surrounding a previous lumen. at the 150 mm stage the mucosa is thrown into a number of stout projections, each has a vascularized mesenchymal core and an epithelial cloth. these projections are in turn split into finger-like villi by transverse furrows. the villi reach their maximal length at the 260 mm stage and then gradually degenerate and slough into the lumen. the villi were completely disappeared at the 730 ... | 1983 | 6670344 |
| homozygous beta-thalassaemia in a part-aboriginal australian. | we describe here the first case of classical homozygous beta-thalassaemia in a part-aboriginal child. the child came from bourke, new south wales, and is the product of a consanguineous mating. his great-great-grandfather was a camel driver from sri lanka who settled in western new south wales. from the family studies, we have found that there are now 17 carriers of beta-thalassaemia in the aboriginal community in northwestern new south wales, and it is anticipated that more part-aboriginal chil ... | 1983 | 6877146 |
| the camel (camelus dromedarius) as an intermediate host for hammondia heydorni. | dogs fed raw camel meat containing two types of cysts shed unsporulated hammondia heydorni oocysts and later sporulated sarcocystis sporocysts in their feces, but were resistant to reinfection with the hammondia cysts. sporulated h. heydorni occysts did not induce an enteroepithelial cycle in dogs, but resulted in the formation of muscle cysts. | 1983 | 6672172 |
| [comparative anatomy of the mandible. functional aspects]. | the structural morphology of the mandibula is presented and correlated to various types of mastication in several mammalian species. the latter include: carnivores (dog, cat, cheetah, lion); omnivores (man, chimpanzee, hog); herbivores (horse, ox, goat, camel, rabbit). while the mandibula is studied as a composite unit, a more analytical, segmental approach has been included, and both are illustrated by x-rays. the aspects presented underline the distribution as well as the local modifications o ... | 1983 | 6679450 |
| studies on the histogenesis of the tunica mucosa of the small and large intestines of the camel (camelus dromedarius). i. histogenesis of the small intestinal mucosa. | the histogenesis of the small intestinal mucosa passes through a previllous stage, comprising development until the formation of villi (at a c rl of about 15 cm), and a villous stage, comprising the further development. in the previllous stage, the mucosa consists of a lamina epithelialis made up of undifferentiated cells with stratified nuclei and a lamina propria/submucosa made up of homogeneous mesenchyme. the villi appear as luminal epithelial outgrowths associated with vascularized mesenchy ... | 1983 | 6670352 |

| studies on the poll glands of the one-humped camel in relation to reproductive activity. i. seasonal morphological and histochemical changes. | the poll glands of the camel have been studied histologically and histochemically. an active gland, as observed between september and march, with a peak period in november and december, consists of sharply demarcated lobules separated by thin strands of connective tissue. alveoli and proximal parts of excretory ducts are either lined with flat/simple cuboidal epithelium or with tall cells possessing distal protruding tips almost occluding the lumina; both segments, i.e. alveolus and proximal par ... | 1984 | 6232249 |
| evidence for the neurotrophic regulation of collagen-tailed acetylcholinesterase in immature skeletal muscle by beta-endorphin. | acetylcholinesterase (ache) was extracted in a high-saline medium from gastrocnemius muscles of rat embryos and young rats aged 14 days' gestation to 40 days post partum. the molecular forms of the enzyme were separated by low-salt precipitation, followed by velocity sedimentation. during gestation, all molecular forms increased in activity, particularly the 16 s (a12) form. during the first 2 weeks of life, there was a large increase in the activity of soluble ache (g forms), whilst the activit ... | 1984 | 6327907 |
| beta-endorphin: demonstration of binding sites in three human neuroblastoma cell lines specific for the cooh-terminal segment of the human hormone. | this communication reports for the first time specific binding sites in human neuroblastoma cells for human beta-endorphin (beta h-ep). three cell lines (imr-32, nmb and kelly) were investigated and found to bind tritiated beta h-ep with an apparent dissociation constant of 2.2-4.2 nm. further characterization with camel beta-ep and synthetic analogs indicated that the binding is most likely mediated by the cooh-terminal segments. beta h-ep-(6-31) had significant potency (15-75%) and beta h-ep-( ... | 1984 | 6329187 |
| efficacy of ivermectin against gastrointestinal nematodes in dromedary camels. | the anthelmintic activity of ivermectin when administered orally and subcutaneously at a dosage of 0.2 mg/kg of body weight was evaluated in 4 trials involving 20 dromedary camels (camelus dromedarius). fecal egg counts were made on the day of treatment and at 2, 4, and 10 weeks after treatment. trichostrongylid egg counts were reduced by a maximum of 100% when ivermectin was administered orally and by greater than 88% when given subcutaneously. egg counts of trichuris spp were reduced by greate ... | 1984 | 6548996 |
| [the coronary arteries of the dromedary]. | the arteries of 30 camel hearts were studied after injecting rhodopas ax 85-15 and latex into the heart vessels, maceration with hcl vapour and careful dissection. the arteries of the dromedary heart are described in detail, the similarities and differences between the perissodactyls and arteriodactyls being taken into account. | 1984 | 6486473 |
| studies on the poll glands of the one-humped camel in relation to reproductive activity. ii. ultrastructural observations. | an alveolus of an active poll gland is lined with cells in various stages of secretory activity. the cells are generally tall and characterised by the presence of a spherical nucleus, a massive golgi complex, numerous mitochondria, granular endoplasmic reticulum, many ribosomes and secretory granules; these are features which constitute evidence of high metabolic and secretory activities. an alveolus of a resting gland, on the other hand, is lined with low inactive cells possessing an infolded n ... | 1984 | 6490529 |
| haemodynamics, blood gas and metabolic changes after anaesthesia with chloral hydrate and magnesium sulphate in camels (camelus dromedarius). | the effects of chloral hydrate and magnesium sulphate (1:1, 10 per cent solution) were evaluated in six healthy adult camels. a dose of 1 ml kg-1 was used. these agents produced satisfactory anaesthesia with good muscle relaxation. the changes in the electroencephalogram showed that the anaesthetic effect lasted for 45 to 60 minutes. tachycardia and hypotension were moderate and within safe limits. electrocardiogram studies showed st segment elevation and primary t wave changes. the acid-base st ... | 1984 | 6424194 |

| estradiol concentration in the serum of the one-humped camel (camelus dromedarius) during the various reproductive stages. | during the estrous cycle of the camel the concentration of estradiol (e2) varies between 9 and 110 pg/ml. in early estrus, the peak level of e2 (74.7 +/- 6.61 pg/ml, n = 11) is maintained for 2.9 +/- 1.83 days. the length of an estrous cycle is 17.2 days. in the 10th month of pregnancy the level of e2 rises abruptly to 338.3 +/- 162.42 pg/ml and continues to rise until the 12th month, peaking at 606 +/- 120.27 pg/ml. the hormone concentration then drops until the day of parturition (mean 113.4 + ... | 1984 | 6510688 |
| tritiated water metabolism during dehydration and rehydration in the camel. | the metabolism of tritiated water in the camel was compared in two 10-day periods, one when water was readily available and the second during dehydration. there was a radically depressed metabolism after 2 days of dehydration. two other experiments examined the absorption rate of drinking water. in one experiment drinking water was labeled with tritium, and in the second experiment dilution of tritium-labeled blood was examined. in both experiments there was a rapid uptake and dilution of the bl ... | 1984 | 6693323 |
| the prevalence and pathogenesis of naturally-occurring haemonchus longistipes infection in sudanese camels. | camel haemonchosis is prevalent in the sudan, especially during the rainy season, with a decrease in prevalence in the dry season possibly due to delayed maturation of the worms. the naturally occurring disease in sudanese camels is characterized by emaciation, anaemia, oedema of the lower parts of the limbs, eosinophilia, hypoproteinaemia, hypoalbuminaemia, hyperglobulinaemia and eosinophilia, as well as elevated blood urea concentrations. | 1984 | 6736305 |
| leydig cell differentiation during the reproductive cycle of the seasonal breeder camelus dromedarius: an ultrastructural analysis. | spermatogenesis and leydig cell development in the dromedary were analyzed at the ultrastructural level and correlated with fluctuations of testosterone synthesis during the mating and nonmating seasons. it was found that (1) spermatogenesis and diameter of the seminiferous tubules are dissociated from seasonal fluctuations of testosterone synthesis as they remain similar throughout the year; (2) the volume of the interstitial tissue and the rate of testosterone synthesis are correlated since bo ... | 1984 | 6745626 |
| carcinogenic activity of condensate from coloquint seeds (citrullus colocynthis) after chronic epicutaneous administration to mice. | in the sahelian countries coloquint seed tar is used in traditional medicine. a condensate from the seed of citrullus colocynthis was obtained in a camel nomad settlement. it contained a large number of polycyclic aromatic hydrocarbons, including known carcinogens [e.g., benzo(a)pyrene, benz(a)anthracene, benzo(b)fluoranthene, benzo(j)fluoranthene]. the dose-related carcinogenic activity of this condensate was established after chronic epicutaneous application to mouse skin. we conclude that the ... | 1984 | 6746706 |
| onchocerciasis in camels (camelus dromedarius) in saudi arabia. | during a survey in 1980-81, 125 of 478 (26.2%) camels in saudi arabia were found infected with onchocerciasis. the prevalence rates in local and imported camels were 93/272 (34.2%) and 32/206 (15.5%), respectively. the disease was characterized by hard nodules in the connective tissue around the nuchal ligaments and in the subcutis. the nodules consisted of cavities containing live, degenerate or dead onchocerca fasciata, inflammatory cells, fibrosis and calcification. the microfilariae were con ... | 1984 | 6520373 |
| morphology of the testis of the one-humped camel in relation to reproductive activity. | histological and morphometric studies on the camel testis have been carried out systematically at regular monthly intervals during a period of one year. the testicular weight was minimal during summer, while the maximum weight was attained during the coldest months from november until march. diameters of the seminiferous tubules were multiphasic with a tendency to be wider during summer. the ratio of the area occupied by seminiferous tubules to that occupied by interstitial tissue revealed that ... | 1984 | 6469852 |
| peripheral blood levels of progesterone in female camels during various reproductive stages. | determination of serum progesterone concentrations over a period of 2 years in female camels during various reproductive stages (estrus, pregnant, nonpregnant, and lactating) suggests that the progesterone levels exceeding 1 ng/ml are reached only if mating is fertile. a cycling camel does not have a luteal phase and mating is probably indispensable for ovulation to occur. | 1984 | 6698390 |
| structural requirements and species specificity of the inhibition by beta-endorphin of heavy acetylcholinesterase from vertebrate skeletal muscle. | the molecular forms of acetylcholinesterase in extracts of gastrocnemius muscle from four vertebrate species and in electric eel (electrophorus) electric organ were separated and identified by low-salt precipitation and velocity sedimentation. the activity of the heavy insoluble (a12) form of human muscle acetylcholinesterase was inhibited by synthetic human beta-endorphin (500 mm). the homologous form in rat muscle extracts was poorly inhibited by human beta-endorphin at the same concentration, ... | 1984 | 6087117 |
