Skin discoloration caused by iron salts.
Monsel’s solution (ferric subsulphate) is an iron salt first described in the literature in 1856 by Leon Monsel (1). Since then it has been widely used by dermatologists as a haemostatic agent in minor surgical procedures, such as tangential excision and punch biopsy (2). Ferric chloride is also a source of ferric ions, which is used in dermatological procedures and is considered more convenien...
متن کاملKinetic Study of the Discoloration of Rhodamine B with Persulfate, Iron Activation
The discoloration of the fluorescent dye, Rhodamine B (Rhd B) by persulphate (KSP), was investigated by spectrophotometric methods. The discoloration reaction of Rhd B by KSP is slow. It’s first order with respect to Rhd B and KSP. It’s effective at any pH and was found to increase linearly for pH< 4, temperature, and after addition of Fe(II) and Ag(I). The rate of discoloration remained the sa...
متن کاملTesting the suitability of metallic iron for environmental remediation: Discoloration of methylene blue in column studies
A new method to correlate intrinsic reactivity and treatability efficiency of metallic iron (Fe) was evaluated. A 2.0 mg L methylene blue (MB) solution was used in gravity fed column experiments. The intrinsic reactivity of nine Fe materials (ten samples) was characterized using the EDTA test. Three commercial Fe materials ZVI1 (0.40 0.80 mm), ZVI9 (0.50 mm) and ZVI10 (0.45 0.55 mm) were tested...
متن کاملThe chemical composition of the egg shells of the potato cyst-nematode, Heterodera rostochiensis Woll.
1. Eggs of the potato cyst-nematode (Heterodera rostochiensis Woll.) were isolated by sieving a suspension of crushed cysts. Eggs were broken open by ultrasonic vibration and the egg shells separated from the released larvae by centrifuging in a potassium tartrate density gradient. About 1 mg. of dried egg shells was obtained from 1000 cysts. 2. The major constituent of the egg shells was prote...
متن کاملPopulation Characteristics and the Nature of Egg Shells of two Phthirapteran Species Parasitizing Indian Cattle Egrets
The prevalence, intensities of infestation, range of infestation and population composition of two phthirapteran species, Ardeicola expallidus Blagoveshtchensky (Phthiraptera: Philopteridae) and Ciconiphilus decimfasciatus Boisduval and Lacordaire (Menoponidae) on seventy cattle egrets were recorded during August 2004 to March 2005, in India. The frequency distribution patterns of both the spec...
