The volatilization of As and its introduction into an inductively coupled plasma ICP ; spectrometer are described. The method is based on the formation of gaseous arsenic trifluoride, generated by the reaction of AsIII with fluoride in sulfuric acid medium. The volatile compound is obtained in a discontinuous or batch mode after injecting 200 ml of As sample and 120 ml of 3% m sodium fluoride solution into 500 ml of concentrated sulfuric acid. The gaseous arsenic trifluoride is fed directly to the ICP torch by a flow 750 ml min-1 ; of Ar carrier gas. When the As emission intensity at 193.696 nm is measured versus concentration a linear calibration graph is obtained between 10 and 500 mg ml-1 of AsIII; the absolute detection limit is 20 ng working with a solution volume of 200 ml. The relative standard deviation for ten measurements of 50 mg ml-1 of AsIII is 5.38%. Interferences due to alkali, alkaline earth, metallic and metalloid elements were studied; anions were also considered. It was observed that interferences from most of the species studied are relatively small. However, the interferences due to alkaline earth elements and Pb are larger than those caused by other species probably owing to sulfate precipitation. Only nitrate produces severe interference. The method was applied to the determination of As in liquid insecticide sample and the results were compared with those obtained using a standard method. Keywords: Arsenic determination; volatile fluoride generation; inductively coupled plasma atomic emission spectrometry; liquid insecticide Sample introduction in inductively coupled plasma atomic emission spectrometry ICP-AES ; has attracted considerable attention.1 Gaseous sample introduction has several advantages over the nebulization of liquids, which is the most common sample introduction technique. Various methods can be used for forming and introducing gases in atomic spectrometric techniques: the formation of volatile compounds and electrothermal vaporization are among the most interesting. Our discussion is focused on the formation of volatile compounds. This possibility has great potential, but few reactions have been adapted to ICP-AES despite the large number of potentially useable inorganic and organic compounds with low boiling temperatures.2 The problem as regards their practical application is their preparation. There are not many reactions that are of analytical use. Typical examples of this technique are the generation of volatile hydrides3 or the cold vapour technique for Hg.4 These compounds have low boiling temperatures and they are readily formed by adding sodium tetrahydroborate to acidified solutions of the elements. Certain inorganic compounds, such as SiF , 5 or organic compounds, such as methyl borate, 6 are 4 volatile at ambient temperature and have been introduced into ICP-AES systems. The preparation of volatile organometallic species based on reactions with alkylboranes, especially sodium tetraethylborate7 and other alkylating agents, has become an important.

Few studies addressed the clinical course of penile fibrosis with intracavernosal injection ICI ; therapy. Such studies are important as they shed some light on what would be prudent to do, and what advice should be given to the patients once a fibrous plaque is noticed during follow-up of patients on long-term ICI therapy. Several factors have been suggested to play a role in the occurrence of penile fibrosis PF ; in patients on ICI therapy. These include the repeated formation and organization of intracavernous hematomas, tunical tears associated with age-related reduction of elastic fibres, ischemic injury to the tunica albuginea, and vasculitis in the subtunical tissues 1, 2 ; . In recent paper by Chew & Stuckey, 2003 3 ; , a 24 month-study of 44 patients with erectile dysfunction ED ; was undertaken to monitor the prognosis of PF, which refers to subcutaneous, tunical or sinusoidal fibrosis occurring during the course of ICI therapy. Out of 245 men receiving therapy with prostaglandin E1 PGE1 ; , 57 patients developed PF with its consequential events of penile pain, curvature, devia and fluphenazine.

INTRODUCTION Although well established in humans, epiduroscopy in canine patients has not been published yet. The purpose of this study was to answer the following questions: Is it possible to perform epidurosopy in dogs? Which is the best approach to the epidural space concerning different heights and weights of the dogs? Which technical equipment is necessary to perform an epiduroscopy? What epidural structures can be seen? What are the potential complications? MATERIALS AND METHODS Anatomical study: Eight fresh canine cadavers of different weight, gender and breed were used to measure the craniocaudal and laterolateral diameter of the lumbosacral foramen in 4 different positions of ventral recumbency. In position A, the hindlegs of the dogs were directed cranially, in position B laterally and in position C caudally. In position D, the hindlegs were hanging off the table. Technical study: Eleven fresh canine cadavers of different weight, gender and breed were used for this part of the study. Preoperative lumbal myelograms indicated no compressive spinal disease. The epiduroscope was a flexible micro-endoscope Medisecur ; with an external diameter of 2.35 mm and a length of 40 cm. All dogs were placed in position A and clipped in the dorsal lumbosacral region. Through a 2 cm median skin incision, the trocar was positioned in an angle of 45 degrees to the vertebral axis of the dogs. In the lumbosacral foramen, the stilett was removed and the angle of the trocar was decreased to between 20 and 25 degrees allowing an easier and straighter access of the epiduroscope into the epidural space. Position of the epiduroscope was evaluated under fluoroscopy guidance. Epiduroscopy was performed under continous lavage with saline 0.9% NaCl Kochsalzlsung ; . Number of attempts of trocar placing, performing of the epiduroscopy, visibility of the epidural structures, iatrogenic damage and complications were recorded. RESULTS Anatomical study: Measurements of the lumbosacral foramen revealed the largest craniocaudal and laterolateral diameter in position A in all 8 dogs. Statistics indicated a significant difference between position A to all other 3 positions and the significant smallest diameter measurements in position C. There was no difference between position B and D. Correlation between body weight and craniocaudal diameter of the lumbosacral foramen was significant in all but position C. All 4 positions were significant between body weight and the laterolateral diameter. Technical study: Placing of the trocar was possible in all patients although number of attempts was strongly correlated p 0.001 ; to the body weight of the dogs. The first attempt was successful in 3 dogs, the second in 4 dogs and third in 2 patients. Dog # 9 had 4, and dog # 7 5 attempts. With the trocar in place, positioning of the epiduroscope was performed without further problems. There was enough room for an additional epidural catheter placed through the working canal of the epiduroscope. Length of the epiduroscope allowed access and visibility of the dorsal epidural space of the lumbal and the thoracolumbal region in medium to big-sized dogs. In small dogs, the midthoracic region could be reached. Visibility of the epidural structures depended on continous flushing during scoping and was better by pulling the scope caudally than by pushing it cranially. Reason for this was the presence of epidural fat that tended to obstruct the optic. Epidural fat was seen within the whole visible epidural space. Its occurence subjectively did not seem to correlate with body weight of the dogs and location within the epidural space. The epidural fat was yellowish to white and appeared glistening. The spinal cord with its dura coverage was the dominant structure in the epiduroscopic picture. It appeared blue-gray or gray-white with small blood vessels on its surface. Spinal nerves could be followed from their origin in the spinal cord towards their exit at the bony surface. Their colour was white tinged with yellow. Many of these spinal nerves were surrounded by easily visible blood vessels. In all patients, these structures could be followed in each segment of the epidural space. Although the epiduroscope was pushed cranially and pulled caudally several times in each patient, macroscopic iatrogenic damage to any of the epidural structures could not be detected in these 11 dogs.

Sometimes, it is necessary to reduce our own direct employment. During the year, out of a total workforce of 40, 300 including China, a total of 2, 359 employees were retrenched in SAB companies around the world, slightly down on last year. Of these, 1, 721 were enforced redundancies, with the balance either taken voluntarily 533 ; or outsourced 105 ; with the jobs preserved. Of the 11 SAB companies reporting reductions in their workforce through retrenchment, nine also reported active programmes to help those affected find alternative employment. Examples include training in new skills and advice on starting up in business. While such retrenchment is always regrettable, it is essential to maintaining business competitiveness and ultimately preserves many more jobs in the company and formoterol.
