Opinion Cough in kids less than 6yrs old whether being with sputum i.e. wet or without i.e. dry and parental asking about any medicine stopping this symptom certainly if being dry i.e. irritating and disturbing sleep. So most studies being done on this subject proved the following: a) It is not wise to suppress cough because it is natural defense mechanism to expel infected mucus i.e. sputum out of the body and clearing the airways to improve oxygenation so never to prescribe antitussive i.e. cough suppressant. b) sputum mucolytic agents and there are many agents their purpose to liquify it and get it watery to be easy expectorated again studies proved that the best muculytic agent is Good Hydration so no need to use except where there is a mucus retention in the lungs like case of brocheictasis. c) WHO recommendation made about 6 yrs back was never to prescribe any cough medicine whether antitussive or mucolytic to kids less than 6 yrs old. Myself and since about 10 years I had not prescribed any cough suppressant to children despite of age but if kids older than 6 years old I do prescribe mucolytic agent made certainly for kids like amydramine syrup which contains antihistamine diphenhydramine and without restrictions. In kids less than 6yrs old again I do prescribe mucolytic made for kids like soolan or Amydramine pediatric syrup in trial to hit 2 birds which are sedating and antihistamine effects and satisfying anxious parents and it does work almost in all cases arabic 6 English 32

Asthma has been considered the most common chronic respiratory disease affecting children and is involved in .different diagnoses of acute bronchiolitis in first year of life Therefore, this research has been conducted to explore the relationship between asthma and bronchiolitis on known asthmatics aging from 6months old to 16 years old frequenting the asthma clinic Tripoli Children Hospital for .)regular follow ups for 3 months (January, February, and march of 2004 The aim of this study: To ascertain the percent (prevalence)of bronchiolitis patients who will develop]e asthma .symptoms later on Conclusively there has been a strong relationship between asthma and bronchiolitis in a way that bronchiolitis pre- .disposes to asthma in 53.5% of patients especially in whom had a family history of allergy

Efficient extraction of genomic DNA (gDNA) from biological materials found in harsh environments is the first step for successful forensic DNA profiling. This study aimed to evaluate two methods for DNA recovery from animal tissues (livers, muscles), focusing on the best storage temperature for DNA yield in term of quality, quantity, and integrity for use in several downstream molecular techniques. Six male Swiss albino mice were sacrificed, liver and muscle tissues (n=32) were then harvested and stored for one week in different temperatures, -20C, 4C, 25C and 40C. The conditioned animal tissues were used for DNA extraction by Chelex-100 method or NucleoSpin Blood and Tissue kit. The extracted gDNA was visualized on 1.5% agarose gel electrophoresis to determine the quality of gDNA and analysed spectrophotometrically to determine the DNA concentration and the purity. Both methods, Chelex-100 and NucleoSpin Blood and Tissue kit found to be appropriate for yielding high quantity of gDNA, with the Chelex100 method yielding a greater quantity (P < 0.045) than the kit. At -20C, 4C, and 25C temperatures, the concentration of DNA yield was numerically lower than at 40C. The NucleoSpin Blood and Tissue kit produced a higher (P=0.031) purity product than the Chelex-100 method, particularly for muscle tissues. The Chelex-100 method is cheap, fast, effective, and is a crucial tool for yielding DNA from animal tissues (livers, muscles) exposed to harsh environment with little limitations.
