The effect of boring sponge infestation on histology and ultra structure of mantle tissue in Perna indica was studied. Transmission Electron Microscopy (TEM) of the mantle tissue infested by boring sponges indicates that they cause irreparable damage to the cell organelles. The variations in the anatomy of the various cell organelles are discussed. Increased cellular autophagy, haemocytosis, hy…
Abstract. Cobalt phthalocyanine tetrasulphonamide was synthesized by reacting cobalt phthalocyanine with chlorosulphonic acid at 130–135 oC followed by addition of thionyl chloride to convert free sulphonic acid to sulphonyl chloride and subsequently amidation with ammonia. It was isolated by acidifying the reaction mixture with hydrochloric acid followed by filtration. It was characteriz…
