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

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. Key words: Biomedical

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. Key words:Syzygium cumini Skeels, RAPD, SSR,

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. Key words: Diurnal

Abstract: Nateglinide is a novel,
highly physiologic, glucose regulator recently approved for the treatment of
type-2 diabetes mellitus. Nateglinide has a rapid
onset and short duration of insulinotropic action
that results in reduction ofglucose level. The
purpose of this study to develop a floating tablet of Nateglinide
to enhance its bioavailability and sustained action. In the present study a
3² full factorial design was employed in which 2 factors were evaluated at 3
levels, experimental trials were performed at all possible 9 combinations.
The independent variables selected for this study were concentration of Ethyl
cellulose (X1) and sodium bicarbonate (X2).% drug release for 30min,1h,
2h,4h,6h, 8h,12h, 16h,24h and floating lag time (FLT) were as dependent
variables. The results of factorial design showed that factor X1 and X2
significantly affect the studied dependent variables. The floating tablet
formulations were evaluated for Bulk density (gm/cm3), Tapped density(gm/cm3), Hausner
ratio(HR), Carr index, Angle of repose, flow property, assay, in-vitro
drug release, hardness, friability,weight
variation. The results of in vitro release studies showed that the
optimized formulation (F8) could sustain drug release (98.33%) for 24h.

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. Key words: Ailments, Ethnobotanical,

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,
