BACKGROUND The induction of the pneumoperitoneum increases intraabdominal pressure (IAP), causing splanchnic ischemia, whereas its deflation normalizes IAP and splanchnic blood flow. We investigated the oxidant-antioxidant status of dogs who underwent low pressure (7 mm Hg), standard pressure (12 mm Hg), and high pressure (15 mm Hg) pneumoperitoneum. RESULTS Twenty-four beagle dogs (12 males ...

OBJECTIVES To study the effect of passive cigarette smoking on plasma oxidative and antioxidative status in passive smoking preschool children and to compare them with controls. METHODS Thirty-four passive smoking (five to 50 cigarettes per day) preschool children (study group) and 32 controls who had never been exposed to cigarette smoke were randomly chosen from children aged from 4 to 6 ye...

BACKGROUND Chronic hepatitis B (CHB) is a global health problem that can result in serious complications associated with collagen degradation. Prolidase is a specific imidodipeptidase that plays an important role in the breakdown of collagen. The aim of this study was to investigate prolidase activity and oxidant-antioxidant status in children with CHB. METHODS This prospective case control s...

To investigate the effect of carvacrol (CAR) on methotrexate (MTX)-induced testis damage in rats. Twenty-four male rats were equally divided into three groups: group I control treatment; group II MTX-treated; group III MTX + CAR-treated. A single dose of CAR was administered intraperitoneally to group III on the first day of the experiment and a single dose of MTX was administered intraperitone...

BACKGROUND This study was designed to evaluate the effects of carvacrol (CRV) and pomegranate extract (PE) on methotrexate (MTX)-induced lung injury in rats. MATERIAL AND METHODS A total of 32 male rats were subdivided into 4 groups: control (group I), MTX treated (group II), MTX+CRV treated (group III), and MTX+PE treated (group IV). A single dose of 73 mg/kg CRV was administered intraperito...

OBJECTIVE The aim of this study was to evaluate the association of tenascin-C (TnC) and total oxidant-antioxidant status to rheumatic or congenital heart valve diseases (HVD) in pediatric patients. METHODS Fifty pediatric patients (25 rheumatic HVD patients and 25 congenital HVD patients) and 20 healthy age-matched control subjects, aged 3-17 years, were enrolled in this observational and cro...

Background. To evaluate the optical quality and related factors in patients with ocular hypertension (OHT). Methods. This was a prospective case-control study. A total of 12 eyes with OHT and 20 control eyes underwent testing with Optical Quality Analysis System II (OQAS II) to evaluate the modulation transfer function cut off frequency (MTF cutoff), the Strehl 2D ratio (SR), objective scatter ...

OBJECTIVES The questionnaire of occupational stress index (OSI) has been popular in the workplace, and it has been tailored for bus drivers in Taiwan. Nevertheless, its outcomes for participants are based on self-evaluations, thus validation by their physiological stress biomarker is warranted and this is the main goal of this study. METHODS A cross-sectional study of sixty-three city bus dri...

INTRODUCTION The aim of this study was to evaluate the serum paraoxonase (PON), arylesterase activities, lipid hydroperoxide (LOOH), sulfhydryl (-SH), and ceruloplasmin (Cp) levels, total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) in adults with obstructive sleep apnea syndrome (OSAS) and to determine whether these oxidant and antioxidant levels can b...

PURPOSE The purpose of this study was to investigate the effect of carvacrol (CAR) on methotrexate (MTX)-induced renal damage in rats. METHODS Twenty-four male rats were equally divided into three groups: group I, control treatment; group II, MTX-treated; and group III, MTX+CAR-treated. A single dose of CAR (73 mg/kg) was administered intraperitoneally to group III on the first day of the exp...
