Antipyretic and anti-inflammatory activities of different extracts of Odina woodier leaves were studied by observing decrease in rectal temperature and reduction in paw edema using albino rats of both sexes. Animals were divided into ten groups, each consisting of six animals. Group 1 served as control and Group 2 received the standard drug. Group 3-10 received various extracts of Odina woodier leaves. Group 3 received ethanol extracts of 200mg/kg and Group 4 received 400mg/kg. Group 5 and Group 6 received ethyl acetate extracts of 200mg/kg and 400mg/kg respectively. Similarly Group 7 and Group 8 received chloroform extracts of 200mg/kg and 400mg/kg. Group 9 received 200mg/kg and Group 10 received 400mg/kg petroleum ether extracts of Odina woodier leaves. For the determination of antipyretic activity, pyrexia was induced by 20% yeast suspension and for anti-inflammatory activity, inflammation was induced using 1% carageenan suspension. The results showed that all the extracts were found to have both antipyretic and anti-inflammatory activities. Among these four extracts, ethanol extract of 400 mg/kg have shown same antipyretic activity after four hours of drug administration as that of the standard Paracetamol drug which caused the reduction of temperature of 1.03 and 1.02 for the extracts and Paracetamol drug . 400mg/kg of ethyl acetate extract after two hours have shown higher anti-inflammatory activity (40.43%) with a probability < 0.001 than the chosen standard drug diclofenac sodium(39.75%) available as an anti-inflammatory drug in the market.Keywords

More than 250 resistivity soundings with Wenner array have been conducted in the basaltic terrain of the Adila basin with an area of about 585 sq km around Solapur, Maharashtra. The resistivity sounding curves have been interpreted in two phases first, by curve matching and later by computer-Aided techniques. Some of the sounding points were chosen near the existing boreholes so as to correlate the sounding results with the borehole lithologs. The potential zones for groundwater accumulation in different horizons were identified by preparing the structure contour maps for the first, second and third interfaces and correlating them with geology and water table contour maps. The earth-sections obtained by interpreting the resistivity soundings are shown as three profiles along NE-SW, NW-SE and E-W directions. The numbers of successful borewells in different villages are also shown in these profiles. In all, 100 locations for the purpose of irrigation were recommended for drilling and 85 of them proved successful.Keywords

Bouguer gravity data over a large central part of the Cuddapah basin have been obtained by digitising the 5-mGal contour map. The regional and residual components have been separated by a newly developed finite element scheme, contoured with colour scale and residual anomalies are modelled for the basement structure in several profiles. The data is thereby rendered more attractive and easily visualised. The thickness of the sediments derived by gravity modelling has been compared with that along two deep seismic sounding (DSS) profiles. The thick columns(˜ 9 km) of sedimentary formations in the Proterozoic Cuddapah basin are likely to interest the organizations dealing with hydrocarbon exploration.
An interesting relationship has been brought out among the three mantle-Derived rocks, i.e. the volcanics of the western margin, the kimberlite emplacement and the dyke swarms. These three features seem to share a common gravity field.
Based on the correspondence between the locations of kimberlite pipes and lamproites and the regional gravity anomalies we suggest the kimberlites and the lamproites to occur along two concentric rings with the centre lying approximately in the southwest region of the Cuddapah basin. Further, the occurrences of kimberlite pipes and lamproites at Vijayawada and Ramannapet on northeast, Narayanpet on the west and Kalyandurg on the southwest led to suggest a third ring. In fact, three new kimberlite pipes have been reported at Siddanpalli between Gadwal and Raichur that lie on the third ring. The gravity studies also indicate the Cuddapah Front on the east to form a possible collision boundary.

The Bouguer gravity anomalies of the Perinthatta anorthosite in north Kerala on the west coast of India are reprocessed by a new finite element space-domain technique in order to delineate the sub-surface extent of the anorthosite body. The residual gravity contour map and corresponding colour image brought out the configuration of the anorthosite body very clearly.Keywords

Kimberlite pipes of Wajrakarur-Lattavaram region in Andhra Pradesh follow some definite patterns depending on regional geology, structure and tectonics. The lithotectonic units with contrasting physical properties often find expression in geophysical measurements. Although direct detection of buried kimberlite pipes by geophysical methods is often difficult, judicious integration of geology, tectonics, and geophysics may suggest favourable zones for detailed investigations.
Based on the distribution of 13 kimberlite pipes discovered so far in the Wajrakarur-Lattavaram region, and on the regional and residual Bouguer gravity and residual magnetic maps derived by a finite element approach, we have attempted to recognize patterns of occurrence of kimberlite pipes. A few potential regions are identified mainly at the intersections of the NE-SW trending faults and the contacts of granites and country rocks.

The Cuddapah, Kaladgi and Bhima basins have generated renewed interest in the recent past among the petroleum geologists for possible hydrocarbons in Proterozoic environment. As regards the Kaladgi basin, besides favourable structural settings such as a series of plunging anticlines and synclines, buried domal structures and thick columns of sedimentary formations, optimism for possible success stems from the surface gas seepage and gas shows in drilled wells in coeval Vindhyan Basin in Rewa and recent discovery in Shahdol near Jabalpur in the Narmada basin in India and oil fields in equivalent formations in Amadeus basin of Australia, Sichauan and Bohai bay of China and Lena- Tunguska basin of Siberia.
It is therefore tempting to apply the new finite element technique to compute the regional and residual gravity fields of the Kaladgi-Badami basin, and to model the residual anomalies with two objectives, first to estimate the sediment thickness, and secondly to know the northern extent of basin under the Deccan Traps. In the first step, the gravity effect of the overlying basalt was removed from the Bouguer gravity data and then the regional-Residual separation was carried out. The resulting residual anomaly was interpreted in terms of basement depths. The maximum depth of the basin is of the order of 36 kilometers which is well comparable to the estimates by geological observations.
