Study design: Amniotic fluid drawn during amniocentesis between 16 to 23 weeks of gestation was used for the study.100 μl and 400 μl of amniotic fluid, were dripped onto two panty liners, respectively. After 5 minutes the indicator strip was removed from the AL-SENSE, dried and examined. The color was recorded at time 0 and 5 minutes, and then every 10 minutes for the first 30 minutes, then at 1, 2, 6 and 12 hours. Results: 50 women were enrolled and 49 completed the study. 100% of both volume samples changed color from yellow to blue during the first 5 minutes and remained stable after twelve hours of follow-up. In the 100 μl subgroup, seven of the 49 samples (14.3%) had a delayed color change and in the 400 μl subgroup one of 49 (2.04%) had a delay in change of color. Conclusion: Amniotic fluid drawn during amniocentesis at weeks 16 - 23 of gestation have a positive, stable staining effect on the AL-SENSE panty liner. Hence, AL-SENSE may be reliable for detection of amniotic fluid leakage during the second trimester.展开更多

Genera of ticks on animals were Amblyomma,Dermacentor,Haemaphysalis and Ixodes.Ixodes granulatus was the only species of licks identified from the animals.Examination of ticks under vegetation revealed 54%adults leading to identification of 3 species of ticks.A total of 7 species of mesostigmatid mites were found.6 species were on rodent,Maxomys mrifer and another one species,Laelaps nuttalli was found only on Leopoldamys sabanus.Laelaps sanguisugus was the only mesostigmatid found infesting tree-shrews.Seven genera of chiggers were identified.From this,5 genera were on rodents,4 genera on tree-shrews and 1 genus on a bat.Conclusions:A total of 16 genera,2 sub-genus and 14 species of acarine ectoparasites were found in this area. Findings of the survey demonstrate the presence of three spesies of acarine ectoparasites which have potential health risk i.e.Ixodes granulalus,Laelaps nuttalli and Leptotrombidium deliense.展开更多
