In various models designed to imitate living cells the surface of the protoplasm is represented by guaiacol which acts in some respects like certain protoplasmic surfaces. The behavior of water in these models presents interesting features and if these occur in vivo, as appears possible, they may help to explain some of the puzzling aspects of water relations in the living organism. When suffic...

The aim of the present work is to purify mucilage polysaccharide extracted from linseed by deproteinization using Trichloroacetic acid (TCA) and Hydochloric (Hcl). 10% w/v TCA deproteinized more than 80% when pH solution was 3. can be considered as an better deproteinizing agent compared hydrochloric evidenced highest efficiency (88.57%)

A method is described for measuring the deoxyribonucleic acid (DNA) content of small samples of adipose tissue or free fat cells. Lipids and acid-soluble nucleotides are first removed by extraction with a cold diethyl ether ethanol mixture containing 10 per cent. ml V of trichloroacetic acid. DNA is then measured by hydrolysing the nucleoprotein residue in a 5 per cent. solution of trichloroace...

We present the case of a 51-year-old moderate hemophiliac with gingival bleeding due to papillary inflammation and adherence in the molar area 47. After dental diagnosis a calculus was removed and 30% trichloroacetic acid was placed by a pressurized applicator for five seconds; the procedure was repeated until the bleeding stopped, then tranexamic acid was placed by a gauze. The patient chewed ...

A convenient synthesis of different types of polyfunctional dihydropyrrol-2-ones via one-pot four component reactions of formaldehyde, dialkyl acetylenedicarboxylates and amines, catalyzed by trichloroacetic acid (Cl3CCO2H) at room temperature has been investigated. The significant advantages of this synthetic method are mild reaction conditions, available and inexpensive material, short reacti...

Trichloroacetic Acid (TCA) was used as an efficient catalyst for the synthesis of highly functionalized piperidines via a one-pot five-component reaction of aromatic amines, aromatic aldehydes and β-keto esters in MeOH at room temperature. The remarkable advantages offered by this method are good yields, simple procedure, short reaction times, no need to column chromatography and an easy wo...

Background: Aphthous ulceration is a common and painful problem. This study was conducted to evaluate the therapeutic effect of local application of trichloroacetic acid and hydrogen peroxide for aphthous ulcers minor. Methodology: This was a double blind controlled study; conducted at Al-Mawanee and Basrah General Hospital. Patients with aphthous ulcers minor were enrolled in this study betwee...
