The lesser degree of acid-fastness of lepra bacilli as compared with tubercle bacilli appears in a disagreeable manner in the difficulty of demonstrating the organisms of leprosy in paraffinized tissues (1). Faraco (2) showed that by ordinary methods of demonstrating acid-fast organisms the lepra bacilli are often not acid-fast, are not differentiated and may be stained by the counterstain. He ...

A B S T R C TEfforts to substitute synthetic dyes on fabrics for natural are currently increasing. Research and innovation extremely needed support those attempts so that the quality of is more competitive than dyes. This study aims optimize dyeing parameters cotton using dye extracts derived from barks Tegeran (Cudrania javanensis), Merbau (Intsia bijuga), Tingi (Ceriops tagal), Jambal (Peltop...

Tuberculosis and leprosy are two well known mankind diseases that are caused by members of the genus Mycobacterium. When originally named in 1896, this genus contained the leprosy bacillus (Mycobacterium leprae) observed by Armour Hansen in 1874 and the tubercle bacillus (Mycobacterium tuberculosis) observed and cultured by Robert Koch in 1882. As time went by, other bacilli similar to those of...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

Global heat, carcinogenic, and viral diseases created due to industrial pollutants has led people shift toward natural products particularly dyes in all walks of life. In this study, U.S. rays up-to 60 min, were used extract the color aqueous medium employed onto silk fabric at selected conditions. It been observed that good strength found when 30 mL acidic ( pH = 4.0) obtained from 6.0 g Harma...

Abstract Synthetic dyes are by far the most widely applied colourants in industry. However, environmental and sustainability considerations have led to an increasing efforts substitute them with safer more sustainable equivalents. One promising class of alternatives is natural quinones; these cyclic organic compounds characterized a saturated (C6) ring that contains two oxygen atoms bonded carb...
