Abstract: Aptamers are useful tools in microorganism
researches, diagnoses, and treatment. Aptamers are specific target
molecules formed by oligonucleic acid molecules, and are not
decomposed by alcohol. Aptamers used to detect Mycobacterium
tuberculosis (MTB) have been proved to have specific affinity to the
outer membrane proteins of MTB. This article presents a biosensor
chip set with aptamers for early detection of MTB with high specificity
and sensitivity, even in very low concentration. Meanwhile, we have
already made a modified hydrophobic facial mask module with
internal rendering hydrophobic for effectively collecting M.
tuberculosis.
Abstract: Sputum smear conversion after one month of antituberculosis
therapy in new smear positive pulmonary tuberculosis
patients (PTB+) is a vital indicator towards treatment success. The
objective of this study is to determine the rate of sputum smear
conversion in new PTB+ patients after one month under treatment of
National Institute of Diseases of the Chest and Hospital (NIDCH).
Analysis of sputum smear conversion was done by re-clinical
examination with sputum smear microscopic test after one month.
Socio-demographic and hematological parameters were evaluated to
perceive the correlation with the disease status. Among all enrolled
patients only 33.33% were available for follow up diagnosis and of
them only 42.86% patients turned to smear negative. Probably this
consequence is due to non-coherence to the proper disease
management. 66.67% and 78.78% patients reported low haemoglobin
and packed cell volume level respectively whereas 80% and 93.33%
patients accounted accelerated platelet count and erythrocyte
sedimentation rate correspondingly.
