Methods Fifty four Balb/C mice of 7 to 10 weeks old under influence of estrogen were inoculated with 5x10 stationaryphase blastoconidia of C. albicans, intravaginally. The mice were divided in three groups, treated with glucan vaginally (5mg/mL) and intraperitoneally (1mg/mL), and the control group that received saline, intraperitoneally. Vaginal lavage was obtained on days 2, 5, 8 e 10 after i...

We have investigated whether an oxygen/ozone (95%O2/5%O3) mixture would have potential against the formation of experimental postsurgical peritoneal adhesions. In two groups of rats, one control intraperitoneally injected with 3 mL/rat of O2 and one intraperitoneally injected with oxygen/ozone mixture (3 mL/rat equivalent to 300 μg/kg ozone), we induced a midline laparotomy and an enterotomy at...

Methods In the solid tumor model, a lump of 350-mg CC-531 tumor cells was placed intraperitoneally in rats having C02 pneumoperitoneum (n = 8), gasless laparoscopy (n = 8), or conventional laparotomy (n = 8). After 20 minutes, the solid tumor was removed through a laparoscopic port or through the laparotomy. In the cell seeding model, 5 x 105 CC-531 cells were injected intraperitoneally before ...

PURPOSE To evaluate the effects of an intraperitoneal solution of methylene blue (MB), lidocaine and pentoxyphylline (PTX) on intestinal ischemic and reperfusion injury. METHODS Superior mesenteric artery was isolated and clamped in 36 adult male Sprague Dawley rats. After 60 minutes, clamp was removed and a group received intraperitoneally UNITO solution (PTX 25mg/kg + lidocaine 5mg/kg + MB ...

Phytotherapy may be an alternative strategy for controlling gastrointestinal parasites. This study evaluated the anthelmintic efficacy of Eucalyptus citriodora essential oil (EcEO). The in vitro effects of EcEO were determined through testing the inhibition of egg hatching and larval development of Haemonchus contortus. EcEO was subjected to acute toxicity testing on mice, orally and intraperit...

Invasion of the intestinal epithelium is thought to be an important step in the pathogenesis of Salmonella infections. Using an in vitro system, we have isolated a genetic locus, inv, that confers to a noninvasive strain of Salmonella typhimurium the ability to penetrate tissue culture cells. Highly virulent S. typhimurium strains carrying inv mutations were defective for entry into Henle-407 c...

Single-dose treatments (5 to 40 mg/kg of body weight given intraperitoneally) of ferrets with 2'-deoxy-2'-fluoroguanosine or its prodrug, 2,6-diamino-purine-2'-fluororiboside, 1 h after infection with influenza A virus significantly inhibited replication of virus in the upper respiratory tract, resulting in amelioration of fever and nasal inflammation. Replication of virus in the lower respirat...

Random l>red Swiss mice were infected with graded decimal doses of Rauscher murino leukemia virus via the intravenous or intraperitonea] routes. Samples of spleen and plasma were then collected at various times after infection. Hioassay of these samples in recipient mice revealed a definite relationship between the amount of virus used to initiate the infection and the amount of virus recovered...
