Malignant melanoma, a disease that is increasing in occurrence and medical concern, is characterized by the excretion of melanogens. Two qualitative tests are recommended for melanogen detection, the Thormählen test and the ferric chloride test. We evaluated the laboratory and clinical performance of these tests by subsequently re-evaluating 201 urine samples that had been submitted for routine...

Repeated intravenous injections of dilute ferric chloride solution in tuberculous rabbits markedly retard the development of the disease as evidenced both by a prolongation in the survival time and by comparison of lesions in control and experimental animals. Partial immunity induced by first infection combined with ferric chloride administration enhances in reinfected animals even more strikin...

Addition of iron and aluminum compounds has become an increasingly popular method to regulate phosphorus eutrophication in lakes and reservoirs. It has been proposed that ferric chloride addition to agricultural runoff entering the northern Everglades could provide a means for enhancing natural mechanisms of phosphorus removal from the wetland. In this study we added ferric chloride to Everglad...

Bonding between laboratory light-cured composite and surface treated Au-Ag-Pd alloy was investigated using newly developed 4-META/MMA-TBB opaque resin. Shear bond strength after 20,000 thermocycles obtained from heated alloy with this method was 25.1 MPa. Ion-coated specimen showed 25.6 MPa after 50,000 thermocycles with decrease in bond strength being small. Ferric chloride treated specimen, h...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...

The clinic treatment of epilepsy with epileptic foci overlapped with eloquent cortex is not satisfactory. In this study we investigated the direct effects of low- and high-frequency electric cortical stimulation (ECS) on ferric chloride-induced seizures in the experimental rats. Results showed that spontaneous seizures were observed in all rats during the EEG recording after the intracortical i...

enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...

Two coagulants, aluminum sulfate and ferric chloride, were tested to reduce natural organic matter (NOM) as a pretreatment prior to polyvinylidene fluoride (PVDF) microfiltration (MF) membranes for potable water treatment. The results showed that the two coagulants exhibited different treatment performance in NOM removal. Molecular weight (MW) distributions of NOM in the tested surface raw wate...

BACKGROUND Controlling parenchymal hemorrhage especially in liver parenchyma, despite all the progress in surgical science, is still one of the challenges surgeons face saving patients' lives and there is a research challenge among researchers in this field to introduce a more effective method. OBJECTIVES This study attempts to determine the haemostatic effect of ferric chloride and compare i...
