چکیده فورفورال، ترکیب شیمیایی سمی است که دارای منابع تولید و مصرف فراوانی است. مهم ترین صنایع مصرف کننده ی آن نفت و پتروشیمی و پالایشگاه های نفت، لاستیک و پلاستیک سازی، و کاعذسازی می باشد. بنابراین فورفورال در پساب حاصل از این صنایع می تواند وجود داشته باشد. در این مطالعه، حذف فورفورال از فاضلاب با استفاده از روش های شیمیایی و بیولوژیکی مورد بررسی قرار گرفت. از فرآیند اُزن زنی کاتالیزوری (cop...
OBJECTIVE To assess the views and prescribing practices of doctors regarding hormone replacement therapy (HRT). METHODS In April 1999, 103 doctors from a teaching hospital participated in a survey. Using a self-administered questionnaire, subjects were contacted at the departments of Internal Medicine, Family Medicine, Obstetrics and Gynaecology, and Orthopaedics. RESULTS Seventy-two percen...
OBJECTIVE Estrogen seems to contribute to glucose homeostasis in women. The objective of this study was to examine the effects of hormone replacement therapy (HRT) on HbA(1c) levels in Japanese postmenopausal women and to determine whether the effects varied with age. RESEARCH DESIGN AND METHODS We studied 99 postmenopausal women taking HRT (mean +/- SD age 56.5 +/- 6.9 years, BMI 21.5 +/- 2....
Case-control study of increased mammographic breast density response to hormone replacement therapy.
Previous studies have demonstrated an association between current hormone replacement therapy (HRT) use and increased mammographic breast density. Many of these studies have also shown that only 20-35% of women initiating HRT respond in this manner. This subgroup of HRT responders may be at an increased risk of breast cancer. We performed a case-control study to investigate how women who experi...
This study was conducted to assess the histopathological features of breast cancers in women diagnosed with breast cancer at 50-64 years of age who have and have not used hormone replacement therapy (HRT). A case-case analysis of the tumors from women aged 50-64 years who participated in a multicenter population-based case-control study of invasive breast cancer was conducted. In-person intervi...
CONTEXT Prolonged postmenopausal hormone replacement therapy (HRT) is associated with increased incidence of breast cancer and, paradoxically, reduced breast cancer mortality. The biological rationale for this discrepancy has not been explored. OBJECTIVE To compare the prognostic characteristics of cancers arising in women who have used HRT with those in women who never have used HRT. DESIG...
AIM Findings from clinical studies in postmenopausal women with late initiation of hormone replacement therapy (HRT) that test whether HRT protects cognitive functions in women are inconsistent. The aim of this study was to investigate the effects of HRT on brain metabolite ratios when initiated in the early postmenopausal period (critical window). MATERIALS AND METHODS Proton magnetic resona...
INTRODUCTION Hormone replacement therapy (HRT) and walking were investigated independently and in combination, to determine which treatment provided most effect on bone turnover in postmenopausal women. METHODS Using a randomised double-blind pilot study, 10 subjects received HRT (transdermal estradiol, 50 μg/day and oral MPA 5 mg/day) and 12 received placebo for 20 weeks. Following a baselin...
This study evaluated the additive effects of hormone replacement therapy (HRT) and a 1-year site-specific resistance-training (RT) program involving two free weight exercises (i.e., squat and deadlift) 2 days/week as a strategy to reverse or attenuate bone loss at the lumbar spine in early postmenopausal women. Participants from a group of self-selected HRT or non-HRT (N=141) users were randoml...
The independent and combined effects of exercise training and hormone replacement therapy (HRT) on body composition, fat distribution, glucose tolerance, and insulin action were studied in postmenopausal women, aged 68 +/- 5 yr, assigned to control (n = 19), exercise (n = 18), HRT (n = 15), and exercise + HRT (n = 16) groups. The exercise consisted of 2 mo of flexibility exercises followed by 9...
