Arthritis in large breed dogs is as common as in humans. Arthritis is closely associated with obesity. Obese arthritic dogs were treated with selected combinations of three supplements including glycosylated type-II collagen (UC-II), Glucosamine HCl (GLU), and Chondroitin sulfate (CH). Dogs were daily supplemented with either placebo (Gr-I), 10 mg UC-II (Gr-II), 2000 mg GLU + 1600 mg CH (Gr-III), or UC-II + GLU + CH (GrIV) for 120 days, followed by a 30-day withdrawal. Dogs were examined on a monthly basis for overall pain, pain upon limb manipulation, and exercise-associated lameness. Gr-I exhibited no improvement. Gr-II showed significant reductions in pain within 30–60 day of treatment. Maximum pain reductions were noted after 120 day (overall pain, 62%; pain upon limb manipulation, 91%; and exercise-associated lameness, 78%). Gr-III dogs showed some pain alleviation, while Gr-IV exhibited marked reductions (57%, 53%, and 60%, respectively). 30-Day withdrawal led to pain relapse in all dogs. Serum samples were analyzed for markers of liver function (bilirubin and ALT), renal and heart function (BUN, creatinine and CK). Body weight and temperature were measured. Serum chemistry, body weight and temperature remain unchanged. Thus, daily treatment of arthritic dogs with UC-II alone or in combination with GLU + CH significantly ameliorates the signs of arthritis, and supplements used in the present study are safe and well tolerated without any side effects. doi:10.1016/j.toxlet.2006.07.311 P26-19 Drug analyses of necrophagous insects and human tissues Marija Definis-Gojanovic, Davorka Kokan, Bogomir Milosevic

This paper reports the results of drug analyses of the developmental stages of two flies species (Calliphoridae and Sarcophagidae), collected from the body of middleage man who had committed suicide approximately 3 weeks prior his corpse was found. Analyses of multiple samples (human tissues and maggots) were performed using a gas chromatography–mass spectrography, and amphetamine was detected in all samples. While the qualitative relationship of the results was without any doubt, the quantitative results were less clear and further research in this area is suggested. doi:10.1016/j.toxlet.2006.07.312 P26-20 Efficacy of different medical herbal preparations as hepatoprotective agents Mohey M.

One of the most common recipes contain from equal parts (w/w) of decoction of (10% concentration): Peumus boldus (leaves), Cichorium intybus (root) and Nigella sativa (seed) (Recipe 1). Glycyrrhazia rhizome (root) was replaced with Cichorium intybus (Recipe 2) or added (Recipe 3). Three groups of normal albino rat were orally administrated 1.5 ml/100 g of Recipe 1 (group 1), Recipe 2 (group 2) or Recipe 3 (group 3) and the control group (group 4) was given 1.5 ml/100 g distilled water daily for 30 successive days. Results for normal groups revealed that Recipe 1, 2 and 3 were decreased plasma ␥glutamyl transferase (GGT): −6.1%, −26.7%, −31.5%; ALT: −3.8%, −13.2%, 17.6%; AST: −5.9%, −6.8%, −21.5%; triglycerides: 1.8%, 0%, −13%; cholesterol: −2.4%, −1.2%, −1.9% and sleeping time: 0.5%, 1.4%, 0.9%, respectively, versus control values. Second set of experiment, four groups of carbon tetrachloride-hepatic damaged rats were given the three recipes with the same above oral doses before carbon tetrachloride for 2 weeks, then followed by another 2 weeks after induction of the hepatic damage. The results indicated that significant decrease in GGT: −70%, −74.5%, −82.0%; ALT: −30.1%, −36.8%, −49.0%; AST: −9.9%, −33.3%, −43.8%; triglycerides: −11.8%, −10.5%, −17.0%; cholesterol: −17.4%, −16.4%, −24.4% and sleeping time: −24.0%, −25.1%, −37.9%, respectively, versus carbon tetrachloride-hepatic dam-
