Intrauterine contraceptive devices (IUCDs) are thought to cause pelvic inflammatory disease by allowing vaginal bacteria to pass into the uterus along the tail of the device. In this study the uterine cavities of 22 women using an IUCD were examined by a multiple biopsy technique. All five uteruses with a tailless IUCD were sterile but 15 out of 17 with a tailed device contained bacteria. The b...

background & aim: homalium letestui pellegr (flacourtiaceae) used traditionally by the ibibios of southern nigeria to treat stomach ulcer, malaria and other inflammatory diseases was evaluated for antiulcer properties.  experimental: the effects of ethanol stem extract of h. letestui (200 – 600 mg/kg) and fractions (aqueous and dichloromethane, 400 mg/kg) on experimentally induced ulcer wer...

BACKGROUND The use of mobile fluoroscopic devices during orthopaedic procedures is associated with substantial concern with regard to the radiation exposure to surgeons and support staff. The perceived increased risks associated with large c-arm devices have been well documented. However, no study to date has documented the relative radiation risk associated with the use of a mini-c-arm device....

We developed a device that delivers fluid through a catheter at a constant rate and can be used in conscious animals to solve a variety of problems. For example, this device can be used for delivering drugs and maintaining intravascular catheter patency. The device provides infusions at low flows (1.0-1.5 ml/day), so that experimental agents may be administered with minimal volume loading of th...

background: intrauterine device (iud) is an effective and long term method of contraception that can be used without continued effort by the user to prevent pregnancy perfectly. pain during iud insertion is one of the obstacles to properly using the device. thus, using different methods of analgesia and anesthesia to alleviate this pain has been studied by many researchers. this review article ...

OBJECTIVES Mechanical ventilation is injurious to the lung. Use of lung-protective strategies may complicate patient management, motivating a search for better lung-replacement approaches. We investigated the ability of a novel extracorporeal venovenous CO2 removal device to reduce minute ventilation while maintaining normocarbia. DESIGN Prospective animal study. SETTING Government laborato...

in the present study, protective effect of teucrium polium l. (labiatae) extract on acetaminophen-induced hepatotoxicity was investigated in mice. animals were divided into six groups, each group consist of 8 mice. group one as the negative control group received normal saline, while group two received only crude extract of t. polium l. (500 mg/kg) for five days and group three as the positive ...
