Abstract
Primary intracranial tumors generally occur as solitary tumors. The association of two primary intracranial tumors of different histogenesis in the same individual is rare, except in cases of phakomatoses or radiation-induced tumors. Meningiomas and vestibular schwannomas (VSs) are one of the commonest tumors occurring intracranially. VS account for 80% of cerebellopontine angle (CPA) tumors, with meningiomas being the second most common tumor of the CPA. The occurrence of both a schwannoma and a meningioma in the CPA is rare. We report a case with coexistent CPA meningioma and VS, which were distinct radiologically on preoperative imaging, however had admixed areas of VS and meningioma on histopathological evaluation.

Abstract
The geographical information system (GIS) has emerged as an efficient tool in delineation of drainage patterns of watershed planning and management. The morphometric parameters of basins can address linear, areal and relief aspects. The study deals with the integrated watershed management of Baliya micro-watersheds, located in the Udaipur district of Rajasthan, India. Morphometric analysis in hydrological investigation is an important aspect and it is inevitable in the development and management of drainage basins. The determination of linear, areal and relief parameters indicate fairly good significance. The low value of the bifurcation ratio of 4.19 revealed that the drainage pattern has not been distorted by structural disturbance. The high value of the elongation ratio (0.68) compared to the circulatory ratio (0.27) indicates an elongated shape of the watershed. The high value of drainage density (5.39 km/km(2)) and stream frequency (12.32) shows that the region has impermeable subsoil material under poor vegetative cover with a low relief factor. The morphometric parameters of relief ratio (0.041) and relative relief (0.99%) show that the watershed can be treated using GIS techniques to determine the morphometric presence of dendritic drainage pattern, with a view to selecting the soil and water conservation measures and water harvesting.

Abstract
Chromium, a widely recognized carcinogenic, mutagenic and redox active metal, is released into aquatic environments by electroplating, tannery and textile industries. Elevated concentrations in sediments and interstitial waters are well documented. Fishes dwelling in chromium waste infested waters are presumed to be affected by its deposits. To evaluate the genotoxic potential of chromium [Cr(VI)] on aquatic bio-system, bottom feeding fishes, Channa punctata, as model fish, were exposed to [Cr(VI)]. The chromosomal aberration test (CAT) was used as biomarker of [Cr(VI)] induced toxicity. The fish were divided into three groups:Group I non-treated controls; group II positive controls, treated with an intra-muscular injection of mitomycin-C at 1 mg/kg body wt; group III exposed to a sublethal concentration (7.689 mg/l) of [Cr(VI)], dissolved in the water. For CAT estimation, short term static bioassays were conducted and samples were collected from the kidneys of fish after 24, 48, 72, 96 and 168 hrs of exposure. The remarkable chromosomal aberrations recorded in the present investigation included chromatid breaks, chromosome breaks, chromatid deletions, fragments, acentric fragments, and ring and di-centric chromosomes, along with chromatid and chromosome gaps. A significant increase in chromosomal aberrations was observed after 72 hrs of [Cr(VI)] exposure. The present study, thus reveals that even for acute exposure, [Cr(VI)] is a genotoxic agent for C. punctata.
