This study was conducted to investigate if silymarin can prevent the adverse effect of oxidative stress induced by carbon tetrachloride(CCl4) on some characters male rat reproductive system. Twenty albino rats were divided into 4 groups, 5 for each included, control group, CCl4 group and plus group. Groups with received dose (150mg/kg) (3ml/kg) at end experiment. The period 35 days. induce toxi...

Although studies of various taxa have shown that males can alter the number of sperm in their ejaculates according to the risk of sperm competition, few studies have examined the extent to which the number of sperm transferred by males across multiple matings is repeatable. We assess the within-male and between-male components of variation in sperm number by counting the sperm in multiple ejacu...

OBJECTIVES To evaluate the result of a surgical technique to insert and secure a standard posterior chamber lens through a simple limbal incision in eyes that had no capsular support or whose capsule was inadvertently ruptured during extracapsular cataract extraction. MATERIAL AND METHOD Retrospective review of the medical records of patients who underwent translimbal fixation of posterior ch...

The human polymorphonuclear leukocyte reaction in response to chemotactic or chemokinetic stimulation is often assayed using the Boyden chamber technique. We present a quick and reliable method for evaluating Boyden chamber experiments, which avoids time-consuming cell counting and does not require expensive equipment. This method is based on assaying human neutrophil elastase, a serine proteas...

insulator, and this in turn carries a 1-, in. brass rod, Q, fixed and sealed in position by a screw cap, R, and 0-ring gasket. The tungsten-anode wire, S (0-1 mm. diameter), is sheathed by a copper tube, T (diameter i16in.) to which it is soldered at its upper end. This is held in the rod, Q, by a small grubscrew. By this means the whole anode assembly is easily taken apart for cleaning and cha...

OBJECTIVE To study the potential interactions in patients with endocardial permanent pacemakers and non-thoracotomy implantable cardioverter defibrillator (ICD) systems. DESIGN Case series and cohort study. SETTING Tertiary referral centre. PATIENTS Fifteen consecutive patients with both endocardial pacemakers (12 dual chamber and three single chamber) and non-thoracotomy ICD systems. M...

INTRODUCTION We report the case of a patient with total hyphema, neovascular glaucoma, long-standing retinal detachment and no light perception vision, who regained counting fingers vision with complete regression of neovascularization following anterior chamber washout, intravitreal bevacizumab, pars plana vitrectomy, and silicone oil placement. This represents a rare case in which a patient w...

PURPOSE To describe an outbreak of Pseudomonas aeruginosa endophthalmitis post cataract surgery. Clinical findings, treatment and outcome are discussed. METHODS Clinical charts review of forty-five patients treated for endophthalmitis in a two-day period. The patients underwent primary vitrectomy, anterior chamber irrigation and intravitreous antibiotic injection. Cultures from vitreous and a...

We have developed a microfabricated biochip that enumerates CD4+ T lymphocytes from leukocyte populations obtained from human blood samples using electrical impedance sensing and immunoaffinity chromatography. T cell counts are found by obtaining the difference between the number of leukocytes before and after depleting CD4+ T cells with immobilized antibodies in a capture chamber. This differe...

background: amiodarone is a drug that is used for treatment of cardiac arrhythmia after cardiac ischemia. this drug as b blocker decreases arrhythmia rate but it has many side effects on different tissues. since there are rare reports about changes of lacrimal glands, this research has been carried out to study the morphological and ultrastructural changes of lacrimal gland cells after amiodaro...
