The method uses a C18 (5 pm particle size) column at ambient temperature with the mobile phase 14.7 mM potassium dihydrogen phosphate (pH 4.6)-8.15 mM tetraheptylammonium bromide in acetonitrile (50 + 50, v/v) at a flow rate of 1.0 mL/min. Quantitation was achieved with UV detection at 300 nm, based on peak area with a linear calibration curve in the concentration range of 0...

During the last few decades, the survival of preterm infants has increased dramatically. Nevertheless, with the increasing number of very young and extremely low birth weight infants, morbidity is still a major problem. Intraventricular Haemorrhage (IVH) is a major complication of preterm birth, and large haemorrhages or haemorrhages associated with parenchymal brain lesions may yield a high rate of future disability. IVH is a complex, multi-factorial disorder. Prematurity and low birth weight remain as its most important risk factors, affecting vulnerability of the germinal matrix as well as the coagulation system...

BACKGROUND: With discrepancies encountered as early as the verification of enzymatic method for quantification of serum creatinine, our research pointed to a later confirmed interference caused by a compound called ethamsylate present in the commonly used antihemorrhagic drug Dicynone. METHODS: We measured concentrations of creatinine of 10 patients with blood taken before and 15 minutes after the intravenous administration of a 500 mg dose of Dicynone. The creatinine concentration was determined using Jaffe method and enzymatic method that utilize Trinder reaction (Roche) in analyzer Cobas c 501 (Roche AG, Basel, Switzerland)...

Intraventricular hemorrhage (IVH) is a major complication of preterm birth, and large hemorrhages may yield significant future disability. During the last few decades, the survival of preterm infants has increased dramatically. Nevertheless, morbidity is still a major problem especially for very young and extremely low birth weight infants. As both, mortality and incidence of morbidities known to influence outcome, show a weekly decline with increasing gestational age, prematurity and low birth weight have been identified as major risk factors for IVH occurrence...

BACKGROUND: Heavy menstrual bleeding (HMB) is an important cause of ill health in premenopausal women. Although surgery is often used as a treatment, a range of medical therapies are also available. Non-steroidal anti-inflammatory drugs (NSAIDs) reduce prostaglandin levels, which are elevated in women with excessive menstrual bleeding and also may have a beneficial effect on dysmenorrhoea. OBJECTIVES: The primary objective of this review was to investigate the effectiveness of NSAIDs in achieving a reduction in menstrual blood loss in women of reproductive years with HMB...

AIMS: Ischemia-reperfusion injury is an important factor in the development of lower urinary tract symptoms (LUTS) that is partly mediated by the generation of free radicals. We investigate the effect of the phytotherapeutic agent Eviprostat, a treatment for benign prostatic hyperplasia (BPH) that has antioxidant and anti-inflammatory activity, on urinary bladder blood flow (BBF), and function in a rat model of bladder overdistension and emptying (OE). METHODS: For 8 days before surgery, OE rats received daily oral Eviprostat (36 mg/kg/day) or vehicle, while sham-operated animals received vehicle...

PURPOSE: We characterized pharmacological effects of the phytotherapeutic agent Eviprostat® on urodynamic parameters, bladder muscarinic and purinergic receptors, and urinary cytokines in rats with cyclophosphamide induced cystitis. MATERIALS AND METHODS: Urodynamic parameters in cyclophosphamide (150 mg/kg intraperitoneally) treated rats were measured by a cystometric method. Muscarinic and purinergic receptors in the bladder and other tissues were measured by radioreceptor assays using [N-methyl-(3)H]scopolamine methyl chloride and [(3)H]αβ-MeATP, respectively...

PURPOSE: To report the anatomic and functional outcome of intravitreal dobesilate to treat recurrent central serous chorioretinopathy (CSC). METHODS: This is an interventional case report in which dobesilate was intravitreally injected in a case of recurrent CSC. Main measures included fundoscopy, Snellen visual acuity (VA) testing, fluorescein angiography and optical coherence tomography (OCT). RESULTS: We present anatomical and functional evidences, obtained as early as eleven days after the treatment, of the efficacy of intravitreal dobesilate, in the treatment of chronic CSC condition...

OBJECTIVES: To clarify the mechanism by which chronic bladder ischemia causes bladder functional changes, and to investigate the involvement of oxidative stress and pro-inflammatory cytokines, and the effects of the phytotherapeutic drug, Eviprostat, on these biochemical marker levels and bladder function. METHODS: Male Sprague-Dawley rats aged 15 weeks were divided into three groups. Arterial injury was experimentally induced by balloon endothelial injury of the iliac arteries, and a 2% cholesterol diet was given for 8 weeks...

It has long been considered that a severe coagulation deficiency in premature newborns could be a major contributing factor in the occurrence of intraventricular hemorrhage (IVH). High-grade IVH has also been shown to coincide with severe derangement of coagulation in extremely low birth weight infants. This review focuses on the relevance of the physiologically developing immature hemostatic system to IVH, and the potential benefit of agents affecting hemostasis for IVH therapy or prevention in preterm infants...

OBJECTIVES: To examine the effect of the phytotherapeutic agent Eviprostat on the stromal-to-epithelial (S/E) ratio, level of macrophage infiltration, expression of the macrophage inhibitory cytokine-1 (Mic1) gene, and tumor necrosis factor-alpha (TNF-α) and interleukin-8 (IL-8) concentrations in prostate tissues in a rat model of nonbacterial prostatitis (NBP). MATERIALS AND METHODS: Ten-month old Wistar rats were divided into 4 groups of 10: (1) NBP non-mixed feed (prostatitis control group); (2) NBP Eviprostat (0...

Two simple, accurate and highly sensitive spectrofluorometric methods were developed for the determination of ethamsylate (ETM). Method I is based on measuring the native fluorescence of ethamsylate in water at 354 nm after excitation at 302 nm. The calibration plot was rectilinear over the range of 0.05-1 μg/mL for ETM with limits of detection and quantitation of 7.9 and 26 ng/mL, respectively. Method II involved synchronous and first derivative synchronous fluorometric methods for the simultaneous determination of ethamsylate (ETM) and hydroquinone (HQ) which is considered as an impurity and/or acidic degradation product...

BACKGROUND: Chronic inflammation in the prostate has recently been recognized as an important component of the symptom progression of benign prostatic hyperplasia. The objective of this study was to evaluate a range of cytokines/chemokines in prostate tissue and urine to identify markers of prostate inflammation in a prostatitis model and to investigate the effect of a phytotherapeutic agent, Eviprostat®, on these markers. METHODS: Ten-month-old male Wistar rats were divided into four groups...

In this paper, a novel method has been established to determine ethamsylate using potassium ferricyanide as a spectroscopic probe reagent. It has been demonstrated that Fe(III) is reduced to Fe(II) by ethamsylate, and that the formed Fe(II) reacts with potassium ferricyanide to form soluble prussian blue (KFe(III)[Fe(II)(CN)(6)]). Beer's law is obeyed in the range of 0.16 - 24.00 µg mL(-1) with the molar absorption coefficient of 2.1 × 10(4) L mol(-1) cm(-1). The detection limit (3 σ/k) is 0.11 µg mL(-1)...

A sensitive and selective capillary electrophoresis method is developed, for the first time, for effective separation and simultaneous determination of aminomethylbezoic acid (PAMBA), cefminox sodium (CMNX) and etamsylate (ETM). The electrophoresis conditions were investigated and optimized.
