PURPOSE To establish a rabbit model for keratoconjunctivitis sicca (KCS) to study autologous submandibular gland transfer for treating severe KCS. METHODS In 2 groups of 10 rabbits, left eyes were operated and right eyes were controls. In the trichloroacetic acid-treated group, the lacrimal and harderian glands and nictitating membrane were removed surgically; the palpebral and bulbar conjunc...

Objective To establish efficacy and safety of medium depth spot peeling with 35% TCA in atrophic and rolled acne scars, in Asian skin (Fitzpatrick skin type III to IV). Patients and methods The study was carried out in the Department of Dermatology Sheikh Zayed Hospital form September 2009 to April 2010. Patients with rolled or atrophic acne scars who presented to skin or plastic surgery outdoo...

Trichloroacetic acid (TCA), in former times used as a herbicide in agriculture, is now ubiquitous and almost evenly distributed in precipitations of the Northern and Southern Hemisphere, despite larger emissions of the possible precursors tetrachloroethene and 1,1,1-trichloroethane in the Northern Hemisphere. The permanent input of a herbicidal compound into most vulnerable ecosystems might lea...

Halogenated hydrocarbons such as Trichloroacetic acid (TCA) are among the most common water supply contaminants in the world. The study was, therefore undertaken to examine the effect of Trichloroacetic acid on the developing testis of Charles foster rat. The rats were randomly placed in the test groups and exposed to various concentrations of TCA i.e. 1000,1200,1400,1600 and 1800 mg/Kg body we...

the total vitamin c content in human plasma is widely accepted as an indicator of the tissue status of vitamin c. a liquid chromatography method with ultraviolet detector (264 nm) for measuring ascorbic acid in human plasma was developed. a c18 reversed-phase column and cetrimide as an ion-pairing agent was employed. ascorbic acid (aa) was measured after reducing l-dehydroascorbic acid to l-asc...

1. The concentrations of total nitrogen, hexosamine and protein-bound hexose and the amounts of these constituents precipitated by trichloroacetic acid were determined in the serum of pigs at various ages from 57 days after copulation to 42 days after birth. The concentrations of the same constituents were also determined in the serum of mature pigs. 2. A rise in the concentrations of total nit...

L-[U-W]Leucine incorporation into the trichloroacetic acid-precipitable fraction of mitochondria after incubation with succinate as energy source was significantly higher with normal rat liver mitochondria than with hypophysectomized rat liver mitochondria. The incorporation was sensitive to inhibition by chloramphenicol, terramycin, dinitrophenol, and NaCN, but not to RNase and cycloheximide. ...

Intracellular ATP concentrations and energy charge were monitored during the growth of Spiroplasma citri and related to the number of colony-forming units, to the pH of the medium and to incorporation of radioactive precursors. Of three different methods used for extracting nucleotides trichloroacetic acid, perchloric acid and boiling Tris/H,SO, buffer the trichloroacetic acid treatment was the...
