Abstract

Confiscated wooden artifacts in the form of sculpture, boxes, beds belonging to 14 -19 centuries were studied for their wood type. Based on very small wood chips taken out from the artifacts, the wood identification was carried out. The artifacts were found to be made up of Juniperus species, Madhuca longifolia (Mahua), Tectona grandis (Teak), Pterocarpus marsupium (Bijasal), Ficus species and Acacia species. All these woods except for Ficus are well known woods famous for their durability and strength. The choice of species of these woods for furniture and sculpture is indicative of good knowledge of wood properties during those times.

Abstract

The paper describes the changes in biochemical parameters of freshwater teleost, Cirrhinus mrigala (Ham.) when exposed to sublethal concentrations of leather dye Bismarck brown with three concentrations (0.6 mg/L, 0.7 mg/L, 0.8 mg/L) at different time intervals (24 hrs, 48 hrs, 96 hrs, 1 week). The serum total glucose showed decreasing trend on exposure to Bismarck brown at different time intervals and at all three concentrations. Under sublethal exposure to Bismarck brown the glucose level decreased in serum. The fall in the glucose content indicates its rapid utilization by the fish as a consequent of dye's toxic effect. The aim of the study is to aware the people to protect the fish fauna fromleather dyes and their effect on the biochemical parameters of the fish Cirrhinus mrigala (Ham.).
