OBJECTIVES The oxygen toxicity risk of hyperbaric oxygen (HBO) treatment has long been of interest. However, there are no comprehensive articles describing the relationship between HBO protocols and oxidative parameters used clinically. The purpose of this study was to determine the effects of various HBO pressure modalities on the oxidative values of rat(More)
BACKGROUND Chitotriosidase is an accepted marker of macrophage activation. In this study, we investigated serum chitotriosidase levels in pulmonary tuberculosis (PTB). METHODS Forth-two patients with PTB and 30 healthy subjects were enrolled in the study. The radiological extent of PTB, radiological sequela after treatment, and the degree of smear(More)
Hyperbaric oxygen (HBO) is a widely used treatment modality in many diseases. A known side effect of HBO is the production of reactive oxygen species. Many antioxidants such as vitamins C and E, riboflavin and selenium have been used successfully to scavenge the reactive oxygen species caused by HBO administration. In this study, we aimed to see if(More)
Pulmonary sequestration is a rare, usually a cystic mass which is composed of nonfunctioning pulmonary tissue that does not communicate with the tracheobronchial tree. In computed tomography pulmonary sequestration is seen as usually a discrete mass lesion, with or without cystic changes, associated with local emphysematous areas located in lower lobes. We(More)
OBJECTIVE The liver is thought to be responsible for multiple organ failure during sepsis. Increase in tissue oxygen consumption is a major component of the septic response. Hyperbaric oxygen (HBO) therapy provides more oxygenation in the whole body. This study examined the effect of HBO alone or in combination with cefepime (CEF) on the liver in septic(More)
BACKGROUND Low serum total cholesterol (TC) concentrations in patients with pulmonary tuberculosis (PTB) have been demonstrated. It was shown that a cholesterol-rich diet might accelerate the sterilization rate of sputum cultures in PTB patients. It is known that smear positivity might be related to the radiological extent of disease (RED) in PTB patients.(More)
BACKGROUND Recent studies show that platelets have important roles in the immune system. Little is known about the clinical significance of platelet indices. Changes in platelet indices, including platelet distribution width (PDW), mean platelet volume (MPV) and plateletcrit, in pulmonary tuberculosis were investigated. METHODS Platelet indices were(More)
BACKGROUND The results of sputum culture for Mycobacterium tuberculosis must be awaited in most cases, which delays the start of treatment in patients with sputum smear-negative pulmonary tuberculosis. We investigated whether plasma chitotriosidase activity is a strong marker for early diagnosis of tuberculosis in patients for whom a bacillus smear is(More)
BACKGROUND There are data about the relationship between morphologic findings on high-resolution computed tomography (HRCT) and the number of acid-fast bacilli (AFB) on sputum smears in patients with pulmonary tuberculosis (PTB). It was also shown that existence of cavities and airspace consolidation might be related to smear positivity in PTB patients.(More)
Cyclophosphamide (CP) is an antineoplastic agent used alone or in combination with other chemotherapeutic agents for the treatment of many neoplastic diseases. Hemorrhagic cystitis (HC) is a major potential toxicity and dose limiting side effect of CP. Recently, it has been shown that endogenous inflammatory mediators are involved in cystitis by increasing(More)
