Background
Infectivity of herbivores with Trichostrongylus nematodes is widespread in many countries, having a major economic impact on breeding, survivability, and productivity of domestic livestock. This study was carried out on Trichostrongylus species isolated from domestic livestock in order to develop an easy-to-perform method for species identification.Methods
Trichostrongylus isolates were collected from sheep, goat, cattle, and buffaloes in Khuzestan Province, southwest Iran. Primary species identification was carried out based on morphological characterization of male worms. PCR amplification of ITS2-rDNA region was performed on genomic DNA and the products were sequenced. Phylogenetic analysis of the nucleotide sequence data was conducted employing Bayesian Inference approach. Consequently, a restriction fragment length polymorphism (RFLP) profile was designed to differentiate Trichostrongylus species.Results
A consensus sequence of 238 nucleotides was deposited in the GenBank for Iranian isolates of Trichostrongylus species including T. colubriformis, T. capricola, T. probolurus and T. vitrinus. The designated RFLP using restriction enzyme TasI could readily differentiate among species having different ITS2 sequence. The molecular analysis was in concordance with morphological findings.Conclusion
Phylogenetic analysis indicated a close relationship among the sequences obtained in this study and reference sequence of relevant species. ITS2-RFLP with TasI is recommended for molecular differentiation of common Trichostrongylus species. 相似文献63.

Objective:
We report on the incidence and the gender, age and ethnic distribution of sarcomas diagnosed between 1980 and 2008 in the multi-ethnic Republic of Suriname.Methods:
Total and average yearly number of cases, crude rates, as well as relevant population data were derived from the records of the Pathologic Anatomy Laboratory and the General Bureau of Statistics, respectively, and stratified according to gender, age groups 0–19, 20–49 and 50+ years, and the largest ethnic groups (Hindustani, Creole, Javanese and Maroons).Results:
Between 1980 and 2008, 258 sarcomas were diagnosed in Suriname, ie at a frequency of nine per year and an annual rate of two per 100 000. Overall, there was 0.9 male per female, two to four cases per year in each age group, and one to three patients in each ethnic group. Soft-tissue sarcomas comprised approximately 80% of overall cases, with a male/female ratio that was approximately 0.5; almost 90% of patients were older than 20 years; more than one-third was Creole. Leiomyosarcoma, fibrosarcoma and liposarcoma were most frequently encountered (90 cases), particularly above 20 years of age, while leiomyosarcomas seemed, additionally, more common in women and Creoles or Maroons. The most numerous bone tumours were primitive neuroectodermal tumour/Ewing tumour and osteosarcoma (37 cases). They were more common in males, the youngest age group, and Hindustanis and Creoles.Conclusions:
The incidence of sarcomas in Suriname, and their gender, age and ethnic distribution in general, seemed comparable with international data. The main exception might be leiomyosarcoma which might have a predilection for Afro-Surinamese. 相似文献64.

Red cell tolerance of admixture with heated saline 总被引:1,自引:0,他引:1
Red cell stability in the face of thermal stress has been evaluated only in the setting of prolonged incubation. This study was conducted to determine red cell tolerance of rapid mixture with heated saline, which exposes red cells to heat only until thermal equilibration, which is a matter of seconds. Half-units of 35-day-old red cells stored in CPDA-1 were mixed at 6 to 10 degrees C in the blood container with an equal weight of 60, 70, or 80 degrees C saline. This resulted in mean mixture temperatures of 30.9, 37.5, and 42.6 degrees C, respectively. Controls consisted of the same mixture, but with 6 to 10 degrees C saline. The red cells in the mixtures were assessed for osmotic fragility, and the supernatant was examined for plasma hemoglobin and potassium. Neither osmotic fragility curves nor supernatant hemoglobin or potassium changed significantly with saline temperatures of 60 or 70 degrees C. When 80 degrees C saline was used, osmotic fragility, supernatant hemoglobin, and potassium all increased significantly (p less than 0.01) over control values. Red cells tolerate rapid mixture with 70 degrees C saline without hemolysis or change in osmotic fragility. 相似文献

Background
Assessment of oral condition, oral care, and informing the attending doctor of unusual oral findings for possible consultation or referral to a dentist are the advocated roles of hospital nurses. The objective of the study was thus to assess the roles of Nigerian nurses in the assessment of oral conditions of hospitalized patients.Methods
This questionnaire-based cross-sectional survey of all nurses caring for hospitalized patients in the University of Benin Teaching Hospital was conducted in the first half of 2010.Results
Of the 384 studied participants, 94.3% considered oral care as an important aspect of nursing care and 73.4% had oral health component in their nursing school curriculum. A total of 80.7% reported suspicious and abnormal findings in hospitalized patients to the attending doctor. Amongst the respondents, 38.0% reported ability to conduct good oral tissue examination. Only 28.1% demonstrated good knowledge of common oral diseases. Three-quarters (73.4%) thought that it is compulsory for nurses to assess the oral condition of hospitalized patients. The 67.7% and 21.9% of the respondents did the assessment on admission and discharge respectively. The majority (90.1%) desired training on oral care of hospitalized patients.Conclusion
There is a need to improve the skill and competence of nurses in the assessment of oral condition to make them a substantive partner in the oral care of hospitalized patients. 相似文献69.

Background
In order to verify the infectivity of rodents with endoparasites in Germi (Dashte-Mogan, Ardabil Province) the current study was undertaken.Methods
Using live traps, 177 rodents were trapped during 2005–2007. In field laboratory, all rodents were bled prior to autopsy, frozen at −20°C, and shipped to the School of Public Health, Tehran University of Medical Sciences, Iran. In parasitological laboratory, every rodent was dissected and its different organs were examined for the presence of any parasite. Blood thick and thin smears as well as impression smears of liver and spleen were stained with Geimsa and examined microscopically.Results
Two species of rodents were trapped; Meriones persicus (90.4%) and Microtus socialis (9.6%). The species of parasites found in M. persicus and their prevalences were as follows: Hymenolepis diminuta (38.8%), Hymenolepis nana (2.5%), Trichuris sp.(40.6), Mesocestoides larva (=tetrathyridium) (3.1%), Capillaria hepatica (6.9%), Moniliformis moniliformis (11.3%), Syphacia obvelata (2.5%), Taenia endothoracicus larva (0.6%), Physaloptera sp. (0.6%), Dentostomella translucida (0.6%), Heligmosomum mixtum (0.6%), Strobilocercus fasciolaris (0.6%),and Aspiculuris tetraptera (0.6%). The species of parasites found in M. socialis and their prevalences were as follows: H. diminuta (17.6%), Trichuris sp. (5.9%), Mesocestoides larva (5.9%), S. obvelata (11.8%), S. syphacia (11.8%), H. mixtum (17.6%), and Aspiculuris tetraptera (11.8%). There were no statistical differences between male and female for infectivity with parasites in either M. persicus or M. socialis. No blood or tissue protozoan parasite was found in any of the rodents examined.Conclusion
Among different species identified, some had zoonotic importance. Therefore, the potential health hazard of these species needs to be considered to prevent infectivity of humans. 相似文献70.
