The toxicity of Salmonella typhosa 0901 W endotoxin for BALB/c mice was potentiated by the administration of 375 mg of cyclophosphamide per kg, 16 mg of daunomycin per kg, 80 mg of methotrexate per kg, 8 mg of pactamycin per kg, 20 mg of polyinosinic-polycytidylic acid per kg, 1,000 mg of procarbazine per kg, and 1 or 4 mg of vincristine per kg. l-Asparaginase (20,000 units per kg) failed to po...

The Subacute Toxicity of l,l-Dimethylhydrazine. CORNISH, HERBERT H., and HARTUNG, ROLF (1969). Toxicol. Appl. Pharmacol. 15, 62-68. Daily injections of 70,50,30, or 10 mg UDMH/kg resulted in the death of 9,6, 5, and 0 rats, respectively, in each group of 10. All deaths occurred within the first 3 days. Animals surviving the first 3 days began to gain weight even though daily dosing was continue...

this study was conducted to investigate the effects of l-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. dietary treatments consisted of: 1) diet with 5% vegetable oil (t1), 2) diet with 5% ve...

A 49-day feeding trial was conducted to examine the effects of dietary glutathione on growth performance, skin antioxidant capacity, immune responses, and gene expression in juvenile taimen (Hucho taimen). The experimental fish had a mean initial weight 5.36 ± 0.13 g were fed diets (approximately crude protein 460 g/kg, gross energy 22 MJ/kg) containing graded amounts (0–control, 100, 200, 400,...

BACKGROUND Pediatric cardiac surgery patients are at high risk for bleeding, and the antifibrinolytic drug tranexamic acid (TA) is often used to reduce blood loss. However, dosing schemes remain empirical as a consequence of the absence of pharmacokinetic study in this population. The authors' objectives were thus to investigate the population pharmacokinetics of TA in pediatric cardiac surgery...

BACKGROUND Honey has been discussed as a therapeutic option in wound healing since ancient time. It might be also an alternative to the commonly used antimicrobials in periodontitis treatment. The in-vitro study was aimed to determine the antimicrobial efficacy against Porphyromonas gingivalis as a major periodontopathogen. METHODS One Manuka and one domestic beekeeper honey have been selecte...

The present study was conducted with the aim of elucidating the possible role of nitric oxide (NO) in the neuroprotective effects of trazodone used to treat chronic fatigue syndrome (CFS) in mice. Male albino mice were forced to swim for a six minute session each day for 7 days and the immobility period was recorded every other day. Trazodone (5 mg/kg and 10 mg/kg) was administered each day 30 ...

background: cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. the aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats.   methods...

A single intraperitoneal injection of endotoxin (40 microg/kg) significantly delayed gastric emptying of a solid nutrient meal. Blockade of nitric oxide synthase (NOS) with 30 mg/kg ip N(G)-nitro-L-arginine methyl ester or 20 mg/kg ip 7-nitroindazole [neuronal NOS (nNOS) inhibitor] significantly delayed gastric emptying in control animals but failed to modify gastric emptying in endotoxin-treat...
