Twenty-one healthy, caucasian, male volunteers completed this randomized single blind, multiple-dose, crossover bioavailability study during which either phentermine HCl capsules (Minobese Forte, reference product) or phentermine base capsules (Duromine, test product) were ingested once daily for 14 days. A washout period of 14 days was allowed between the two treatment phases. On profile days (day 14 of each treatment phase) subjects remained recumbent for 24 hours after drug administration. Serial venous blood samples were drawn over the 24 hour dosing interval for plasma phentermine assay by gas chromatography. The 90% confidence intervals for the "test/reference" mean ratios of the pharmacokinetic variables Cmax,norm, Cmin,norm, AUCnorm (normalized for difference in the dose of phentermine base), %PTF and T75% Cmax, all fell within the bioequivalence range of 80% to 125%. With the aid of trough plasma phentermine concentrations, it was established that steady-state was reached after 14 days of once daily administration of either product. Adverse events experienced on both treatments included prolonged or recurrent episodes of insomnia, nausea, headache, dry mouth and dizziness. No clinically relevant changes in clinical chemistry or hematology variables occurred during the study.

The internal contamination with depleted uranium (DU) isotopes was detected in British, Canadian, and United States Gulf War veterans as late as nine years after inhalational exposure to radioactive dust in the Persian Gulf War I. DU isotopes were also identified in a Canadian veteran's autopsy samples of lung, liver, kidney, and bone. In soil samples from Kosovo, hundreds of particles, mostly less than 5 microm in size, were found in milligram quantities. Gulf War I in 1991 resulted in 350 metric tons of DU deposited in the environment and 3-6 million grams of DU aerosol released into the atmosphere. Its legacy, Gulf War disease, is a complex, progressive, incapacitating multiorgan system disorder. The symptoms include incapacitating fatigue, musculoskeletel and joint pains, headaches, neuropsychiatric disorders, affect changes, confusion, visual problems, changes of gait, loss of memory, lymphadenopathies, respiratory impairment, impotence, and urinary tract morphological and functional alterations. Current understanding of its etiology seems far from being adequate. After the Afghanistan Operation Anaconda (2002), our team studied the population of Jalalabad, Spin Gar, Tora Bora, and Kabul areas, and identified civilians with the symptoms similar to those of Gulf War syndrome. Twenty-four-hour urine samples from 8 symptomatic subjects were collected by the following criteria: 1) the onset of symptoms relative to the bombing raids; 2) physical presence in the area of the bombing; and 3) clinical manifestations. Control subjects were selected among the sympotom-free residents in non-targeted areas. All samples were analyzed for the concentration and ratio of four uranium isotopes, (234)U, (235)U, (236)U and (238)U, by using a multicollector, inductively coupled plasma ionization mass spectrometry. The first results from the Jalalabad province revealed urinary excretion of total uranium in all subjects significantly exceeding the values in the nonexposed population. The analysis of the isotopic ratios identified non-depleted uranium. Studies of specimens collected in 2002 revealed uranium concentrations up to 200 times higher in the districts of Tora Bora, Yaka Toot, Lal Mal, Makam Khan Farm, Arda Farm, Bibi Mahro, Poli Cherki, and the Kabul airport than in the control population. Uranium levels in the soil samples from the bombsites show values two to three times higher than worldwide concentration levels of 2 to 3 mg/kg and significantly higher concentrations in water than the World Health Organization maximum permissible levels. This growing body of evidence undoubtedly puts the problem of prevention and solution of the DU contamination high on the priority list.
