Abstract: The albino Wistar rats were used to investigate the effect of thyroxine administration on the activity of citric acid, α-Amylase, creatine phosphokinase (CPK), creatinine, cholesterol and triglycerides level in blood serum and citric acid in liver and kidney. Two groups of rats were taken for the experiment. One group was injected subcutaneously with 200 μl of thyroxine/50 g of body weight, the other group served as control. The animals were vivisected with anesthesia after intervals of 24, 48, 72 and 96 hours α-Amylase and CPK levels in blood; citric acid level in liver and kidney of control and thyroxine treated rats. The results showed that the α-Amylase activity remained unaltered (100 g/h/l) throughout the experiment. However, citric acid level found to be 460 mg in the liver and 415 mg in kidney of control rats. The values slightly increased to 480 and 680 mg in respective tissues of thyroxine treated animals for 24 hr. The values decreased in 48 and 72 hours of treatment. Further the values found to be increased after 96 hours of treatment. Although the thyroxine treatment altered citric acid, Creatinine, Cholesterol, Triglycerides and CPK levels in the tissues, the serum α-Amylase was not influenced by the thyroxine. The study suggests that the thyroxine acts as a regulator all the above parameters in the cellular level.

Abstract: The present study reveals the pharmacognostic studies root of Stachytarpheta jamaicensis (L) Vahl. The objectives of the present work comprises of collection, identification, macroscopical, Ph of aqueous solution, soluble ash, alcohol soluble extractive, flouresence analysis of root. The root section was taken and microscopical studies were carried out, the root shows derived from the cork, the periderm tissue is formed, which replaces the epidermis in the outer layer. The next tissue identified inwards was the cortex. Sclerenchyma was seen as a ring in the roots, while as a group, formed from a group of cells, in the mature ones. In the middle, xylem tissue occupies a large area, just below the phloem tissue.
