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

The detection of somatic mutations in tumours is essential for the understanding of cancer development and targeting therapy. The screening for BRAF V600E mutation is employed in clinical practice in Libya for its prognostic and potentially predictive role in patients with metastatic colorectal carcinoma (mCRC). Using of BRAF mutant DNA and wild type DNA targets, we found that the sensitivity of allelic discrimination-Real Time PCR was applicable. The Real Time PCR assay displayed increased analytical sensitivity in detecting the BRAF V600E mutation. The association of BRAF mutations with clinical and pathological features was assessed using Real Time PCR assay. Qiagen Real Time PCR Platform was utilised using a set of primers. forward 5-GAC. CTC. ACA. GTA. AAA. ATA. GGT. G 3, reverse 5-TCC. AGA. CAA. CTG. TTC. AAA. CTG. A. 3. Our study indicates that Real Time PCR-based assays is convenient to detect the BRAF V600E mutation in CRC and that BRAF mutations screening should not be restricted to selected patients on the basis of the clinicalpathological characteristics. arabic 9 English 63

Exposures to a wide variety of environmental substances are negatively associated with many biological cell systems both in humans and rodents. Trichloroethane (TCE), a ubiquitous environmental toxicant, is used in large quantities as a dissolvent, metal degreaser, chemical intermediate, and component of consumer products. This increases the likelihood of human exposure to these compounds through dermal, inhalation and oral routes. The present in vivo study was aimed to investigate the possible cellular and molecular etiology of liver abnormality induced by early exposure to TCE using a murine model. The results showed a significant increase in liver weight. Histopathological examination revealed a TCE-induced hepatotoxicity which appeared as heavily congested central vein and blood sinusoids as well as leukocytic infiltration. Mitotic figures and apoptotic changes such as chromatin condensation and nuclear fragments were also identified. Cell death analysis demonstrates hepatocellular apoptosis was evident in the treated mice compared to control. TCE was also found to induce oxidative stress as indicated by an increase in the levels of lipid peroxidation, an oxidative stress marker. There was also a significant decrease in the DNA content of the hepatocytes of the treated groups compared to control. Agarose gel electrophoresis also provided further biochemical evidence of apoptosis by showing internucleosomal DNA fragmentation in the liver cells, indicating oxidative stress as the cause of DNA damage. These results suggest the need for a complete risk assessment of any new chemical prior to its arrival into the consumer market.
