Abstract: Gomti river receives industrial as well as domestic wastes from various drains of Lucknow city. In this process the water of river Gomti gets contaminated with heavy metals and other pollutants. In the present study impact of above wastes on the Gomti river water have been investigated from January 2009 to June 2009. For this, six sampling sites were selected and the samples of water were collected and analyzed month wise. The results indicate that the pH of Gomti water is under acceptable limit of water quality. Chemical oxygen demand at one site is higher than WHO permissible limit. Therefore water should be treated before use of various purposes’. All the other parameters like chloride, sulphate, alkalinity, chromium and lead are under permissible limits..

Key words: Gomti river water, Fluoride, Alkalinity, Dissolved oxygen and Metals

Abstract: Biomedical waste is generated in hospitals, research institutions, health care teaching institutes, clinics, laboratories, blood banks, animal houses and veterinary institutes. These wastes have potential to spread dangerous diseases if disposed indiscriminately. The study reveals the existing scenario of different types of clinical wastes alongside the domestic wastes and primary results on the physico - chemical properties of the hospital waste water before their discharge in the municipal sewerage system and their effects on the environment. It was observed that the major producer of bio-medical waste is KGMC i.e. on an average 2195 quintal/year where as the minimum producer of bio-medical waste is Sanjivani Medical Center and Javitri Nursing Home i.e. 33.50 quintal respectively. As per the estimation and survey the total biomedical waste generation in Lucknow is more than 2.0 MT/day. The effluents present an important concentration and high BOD, COD and Suspended solids values showed that water is highly contaminated.

Abstract: Syzygium cumini Skeels (Jamun), known for its nutraceutical and antidiabetic properties, exhibits appreciable variability in their natural population.The genetic variability among the jamun accessions were assessed using dominant (randomly amplified polymorphic DNA - RAPD) and co-dominant (direct amplification of minisatellite DNA - DAMD, simple sequence repeats -SSRs) marker systems. A total of 117 fragments were generated across the eleven accessions with 92 being polymorphic. The number of bands produced by each primer varied from 6 (OPB-12 and OPG-13) to 17 (OPG 3) with an average of 10.63 per primer. The cluster analysis through UPGMA method produced a dendogram depicting genetic relatedness among the jamun accessions based on molecular diversity in which the accessions were grouped into three clusters. The distance matrix generated by Jaccard’s genetic distance coefficient ranged between 0.488 (CISH J-42 and PKM) to 0.788 (J -34, J-37 and PKM). Among four minisatellite primers tested, 33.6 primer displaying 85.71 % polymorphism. Out of ten SSR primers pairs the two primer viz., mPgCIR 15 and mPgCIR 16 exhibited cross species amplification, however, multi-allelic banding was exhibited limiting its use in characterization. Transferability of guava SSR markers was confirmed validating highly conserved regions among jamun accessions.

Abstract: The free living copepods are considered as zooplanktons and consume as food by fishes. In the present study diurnal fluctuations in population density of copepods in relation to temperature, dissolved oxygen, pH, acidity and alkalinity were studied in Yassbolagh Dam which is situated in North West to Arak city. The study covered four diel periods in three months of summer, 2008. The Copepods are a sub-class of the class Maxiliopoda, sub phylum Crustacean and phylum Arthropoda, and in this study they were represented by 8 genus, 11 species and three orders (Cyclopoida, Calanoida and Harpacticoida) respectively. Maximum population density observed in D. lintoni . The high population density of copepoda in 12 and 18 possibly is due to their diurnal habitat, more water temperature, and relatively moderate oxygen concentration.

Abstract: The present study revels about the vast diversity of herbal plants used by tribes as well as poor villagers of Bahraich district. The potential of ethnobotanical research and need for documentation of traditional knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind is carried out because most of the villages of Bahraich district are not having sufficient medical facilities. But all the villages have the traditional medicines and treatments to cure all the ailments. The rural population has to depend on the local ethnic doctor called as viaday or hakim. They prepare medicines from the medicinal plants available in their locality. They follow all the traditional and ethnic method of preparing the medicine. Bahraich has well blessed phytodiversity which is a rich source of medicinal plants as well as ethnic communities. The remote locality, poverty illiteracy and lack of touch with modern civilization make them confined to hold on traditional faith hence they are wholly dependent on indigenous plants for the treatment of various ailments. The investigation was performed by collection of local medicinal plants in consultation with the local tribes as well as poor villagers. The common medicinal plants used by rural tribes were studied and about seventy six plant species belonging to sixty nine genera representing thirty six families were found to be utilized in the treatment of various twenty five ailments viz. antidote for snake and scorpion bite, arthritis, burn, cough, cold, coryza, constipation, conjunctivitis, diabetes, ear pain, fever, gastrointestinal troubles, headache, insomnia, jaundice, leucorrhoea, mouth ulcer, respiratory troubles, skin problems and skeletal problems etc. Various medicinal plant parts viz. leaves, flowers, bark, latex, seeds, rhizome, root, sometimes whole plant were used as ethnomedicine. For each plant species, details on scientific name, authors name, vernacular name, family name, as well as use were provided along with parts harvested for treatment and the mode of administration.

Abstract: Blight implies a sudden and extensive damage of leaves. In many leaf diseases the area of necrosis is limited which gives the appearance of spot. Pumpkin is major vegetable crop in District Sultanpur. The disease is sporadic in Sultanpur and nearby districts. The fungus occurs naturally in most soils and can infect pumpkin at most stages of growth when there is excess soil moisture and warm, wet weather. The fungus overwinters in soil as thick-walled oospores. It has been described as the ‘most destructive disease of cucurbits’ because ‘nothing causes greater loss’. Total crop loss may occur in some fields. The present study is made to find out disease cycle occurrence and mode of prevention of pumpkin blight disease.

Key words: Blight, Pumpkin, fungus, sporadic
