COMPARATIVE PHARMACOGNOSTICAL STUDY OF THE GENUINE AND MARKET SAMPLES OF THE STEM BARK OF CIRABILWA (HOLPTELEA INTEGRIFOLIA PLANCH.)

Context: The stem bark of Cirabilwa (Holoptelea integrifolia Planch.) is used for treating various disease conditions including Dyspepsia, Flatulence, Colic, Helminthiasis, Vomiting, Skin diseases, Diabetes Mellitus, Haemorrhoids and Rheumatism in traditional system of medicine since ancient times. As a part of a proposed clinical study, sufficient quantity of the plant drug was required to evaluate the antidyslipidemic effects, which was procured from market. Aim: This study was designed to identify and compare the pharmacognostical features of the genuine hand collected samples and market samples of the stem bark of this medicinal plant, so as to prove the genuinity of the market samples before using it for clinical study. Materials and Methods: Macroscopic and microscopic methods were applied to determine the diagnostic features of the shade dried samples of the intact stem bark of both samples of the drug and was compared with the available data. Results: The shape, color, thickness, odour, consistency, fracture and surface characteristics were determined. Compound microscope images showed the presence of ray cells, stone cells, starch grains, rhomboidal crystals in both the samples. Conclusion: The study confirmed the identity of both genuine and market samples. Comparable results were obtained which proved the genuinity of the market samples of the stem bark of Cirabilwa (Holoptelea integrifolia Planch)

A Review on Transport Modeling Of VOCs In Subsoil

ABSTRACT: Volatile Organic Compounds (VOCs) are the most common subsurface environment contaminants usually in the form of Non-Aqueous Phase Liquids (NAPL) through Leaking Underground Storage Tanks (LUSTs) and pipelines, accidental spills, land disposal sites, and industrial waste impoundments. VOCs are toxic, mutagenic and carcinogenic. Hence, VOCs in subsoil pose a serious threat of groundwater contamination. Organic compounds, owing to their persistence and volatility, present unique environmental problems in the vadose zone of soils. The uncertainty in transport mechanisms and subsoil environment pose a serious challenge in developing transport model for VOC compounds. Apart from advection and dispersion, VOC also undergo several complex chemical reactions such as adsorption, degradation, volatilization and ionic exchange. The transport mechanisms and transport modeling studies for VOCs are largely based on extensive field studies and relevant laboratory experiments. The focus here is to review the role of transport mechanisms and modeling aspects of organic compounds in petroleum fuels and other such liquids and liquid wastes that have the potential to migrate through subsoil to groundwater and also to atmosphere by vapor diffusion

An unusual bumber catch of white prawn, Penaeus indicus from Kovalam bay near Madras

In the history of the fishing village, namely, Kovalam (lat. 12°47'N long. 80°15'E), formerly known as Covelong, situated 35 km south of Madras City, heavy landings of the Indian white prawn, Penaeus indicus caught with gill net have occurred for the firsi time during 16th-20th December, 1984. Recent mark-recapture experiments on P. indicus have also established the fact that a longer migration of tagged white prawns took place from Cochin, (place of release) to Ovari - Manappad fishing villages on the southeast coast (Tinnaveli coast), covering a distance of 330-380 km in 68 to 103 days at a rate of 3.5 to 5.5 km/day. The southward migration of white prawns during the present study was in conjunction with the prevailing southerly current along the coast

Assessment of (210)Po and (210)Pb in marine biota of the Mallipattinam ecosystem of Tamil Nadu, India.

To provide baseline data on background radiation levels for the future assessment of the impact of nuclear and thermal power stations, a systematic study was carried out in the Mallipattinam ecosystem of Tamil Nadu, India. Mallipattinam is located between the Kudankulam and Kalpakkam nuclear power plants and near to Tuticorin thermal power plant. Water, sediments, seaweeds, crustaceans, molluscs, and fish were collected to measure the concentrations of (210)Po and (210)Pb. The concentrations of (210)Po and (210)Pb in most samples are comparable to values reported worldwide. In fish, the concentrations of (210)Po and (210)Pb are in the range 16-190 Bq kg(-1) and 8-153 Bq kg(-1), respectively. The concentration factors of (210)Po and (210)Pb for the biotic components ranges from 10(3) to 10(6)
