| tick-borne diseases of domestic animals in northern nigeria. ii. research summary, 1966 to 1976. | during the first 10 years of its existence, the department of parasitology and entomology of the faculty of veterinary medicine, ahmadu bello university in zaria, nigeria, confirmed or described for the first time the occurrence of 25 different tick-borne parasites of domestic animals in the northern part of the country. most of these organisms occur as inapparent infections but may serve as complicating factors in any adverse host condition. the transmission of babesia bigemina by boophilus dec ... | 1977 | 339447 |
| a double-blind comparison of 1% hydrocortisone plus 10% urea ('alphaderm') and 0.1% betamethasone 17-valerate in the treatment of non-infective inflammatory dermatoses. | a double-blind controlled trial was carried out over a period of 3 weeks to assess the effectiveness of 1% hydrocortisone, in a specialized carbamide drug delivery system, compared with 0.1% betamethasone 17-valerate cream in the treatment of 21 patients with bilateral, symmetrical, non-infective inflammatory dermatoses. the trial preparations were applied topically twice daily, each to one side only during the trial. although overall patient preference tended to favour betamethasone 17-valerate ... | 2004 | 343995 |

| quantitative estimation of leishmanial antibody titers by enzyme-linked immunosorbent assay. | the response to immunization against leishmania braziliensis in rabbits was followed by measurement of antibody by enzyme-linked immunosorbent assay (elisa), passive hemagglutination, complement fixation, and countercurrent immunoelectrophoresis. passive hemagglutination and complement-fixation titers were interpreted according to standard methods, whereas elisa exact titers were derived by the equation y = a-b log x, which describes the straight line that results when absorbances are plotted ag ... | 1979 | 387886 |
| prescribing procrastination. | in his everyday work the family physician sees many patients whose problems have been diagnosed but for whom postponement of an active treatment plan is indicated. the physician must therefore prescribe procrastination in a carefully planned way. i describe some ideas and practical methods for doing this. | 2004 | 529244 |
| [post-cholecystectomy condition: duodeno-gastric reflux and bile acid concentration in the gastric juice]. | in cholecystectomized patients highly significantly more frequently a duodenogastric reflux was found than in a group of patients with a healthy abdomen and a group of patients with cholelithiasis. the average concentration of bile acid in the gastric juice was after the removal of the gall-bladder manifoldly higher than in the control groups. the number of patients with concentrated reflux was also highly significantly larger than in patients with cholelithiasis not operated on and in patients ... | 2005 | 538988 |

| field experience with heartwater (cowdria ruminantium) in cattle. | observations are reported on 2743 animals immunised against heartwater since 1958. the methods of immunisation and control of reactions are discussed. this procedure is not without risk and 0,83% of the animals died in spite of treatment. bos indicus breeds appear to have a greater resistance to heartwater and are relatively easy to immunise. of the box taurus breeds the south devon, the jersey and the charolais seem to be particularly susceptible. older animals and pregnant cows are considered ... | 1979 | 553971 |
| investigations on the natural and acquired resistance of cattle to artificial infection with cowdria ruminantium. | sixty cattle, artificially immunized against c. ruminantium, were challenged 3, 6, 12 and 24 months later. levels of conglutinin were determined in pre-immunization serum samples. there appeared to be a relationship between the pre-infection levels of conglutinin and the susceptibility of the animals to heartwater: at the time of immunization 31 out of 60 cattle (51,6%) with levels in the low-titre range (1:100-1:160) showed a typical febrile response, whereas 29 (48,4%) with conglutinin levels ... | 1979 | 553974 |
| heartwater in nigeria. ii. the isolation of cowdria ruminantium from live and dead animals and the importance of routes of inoculation. | a study was carried out to determine which materials from animals dying or dead of heartwater could initiate the disease in susceptible goats, using the intravenous and subcutaneous routes. c. ruminantium was consistently isolated by intravenous injection of the whole blood or of lung macrophages and by subcutaneous injection of brain homogenate. in animals dead of heartwater, it appeared that isolation of the organism was achieved only when extensive post-mortem autolysis had not supervened. ex ... | 1978 | 625798 |
