fuel induced histopathological alterations in the gill and liver tissue of Oreochromis
niloticus Saliu, Joseph Kayode* and Salami,Adekunle Shamusideen University of Lagos,Department of

Abstract: In this study the effect of sub lethal
concentrations of drilling fluid, 6.1062ml, and diesel fluid, 0.2742ml,
(1/100thof the 96hr LC50) on
the gill and liver tissue of Oreochromis niloticus was investigated. The fishes were exposed
to sub lethal concentration of both treatments for twenty eight days. The
toxic effects of the drilling fluid and diesel fuel was time dependent and
significant histological alterations observed were inflammations and deposition
of pigments on the epithelial mucosa of the two tissues. The histological
alterations induced by these 2 fluids in the gill and liver are reliable
biomarkers for the aquatic environment. Key words: Drilling
fluid, diesel fuel, Histological alterations, Inflammation, Pigment
deposition and Oreochromis niloticus. |

Abstract: This paper deals with strategy and practice to
make the buildings Human Resource and sustainable development. First time the
concept of sustainable development was formalized by World Commission on
Environment and Development (WCED) in 1987 and the Brundtland
Report by the World Commission on Development and Environment was published
on sustainable development at the same time. The report mentions that
“Humanity has the ability for sustainable development to ensure the needs of
the present without compromising the ability for future generations to
satisfy their needs”. The definition of sustainable development is based on 2
concepts, i.e. the concept of needs and the idea of confinement of the
environment capacity to respond to current and future needs. The 1992 Rio
Declaration issued 27 principles that guide the actions of various factors in
favor of sustainable development. Some of these principles have been defined
and interpreted in multiple ways and this has led to a series of debates and
controversies. The approach of sustainable development has more than one
interpretation starting from the key moment in 1987. So, sustainable
development was seen as a welfare growth in the long run and at the same time
it was also considered as consumption growth in time and consumption of human
resource. Human resources are central to economic development and can be
increased in value and productivity by investment in human beings e.g. in
their education and health. But human resources should be utilized in such a
manner that their perspective outcomes of utilization leads to sustainable
development. Key words: Human
resource, Sustainable development |

Abstract: The
present investigation was conducted to study intercropping of coleus in
tamarind plantation compared to sole cropping in open area under irrigated
condition. The experiment was laid out in eight years old tamarind plantation
spaced at 6m x 6m (as intercrop) with three replications. Photosynthetically
active radiation (PAR) interception by coleus crop at 150 days after planting
(DAP) as intercrop in tamarind plantation was 36570 lux
comparedto 48345 lux in
open area. Significantly higher number of primary roots (19.46) and dry
weight of roots recorded under intercropping (18.06 g/plant) compared to sole
cropping (10.13 and 18.06 g/plant). Coleus grown as intercroping
in tamarind plantation recorded higher yield (26.33 q/ha) compared to sole
crop in open area (14.55 q/ha). Key words: Coleus,

Abstract: Traditional
systems of medicines are being used since vedic
period. The present work is undertaken for the documentation of
ethno-medicinal knowledge existing among the dwellers of North-Tarai forests of U. P. which is full of green natural
forests and rich biodiversity as well as tribal communities and ethnic
culture. Tribals are the store house of such
traditional knowledge because they have faith & belief on traditional
medicines as well as they are familiar with nature so they use herbal
medication. Surveys were conducted in the region. Questionnaire method was
adopted for the investigation. During the survey more than hundreds of plants
were investigated & collected which are being used for the treatment of
various ailments in which sixty seven plant species belonging to sixty two
genera representing thirty seven families are reported being used for the
treatment of joint & muscle pain. From the collected data of
questionnaire different traditional medicinal plants are being tabulated
alphabetically family wise along with their author name, vernacular name,
method of medicine preparation and mode of administration. The study
indicates that the present work is helpful in production of cheap and effective
medicines as well as in the conservation of natural biodiversity. Key words: Ethno
medicinal plant, north- tarai forests,
biodiversity, traditional knowledge, joint and muscle pain. |

Abstract: Effect
of body weight and sex on the rates of ammonia excretion and metabolism,
gonad weight, gonadosomatic index and the number of
ova production were studied in an ornamental fish, Xiphophorus
helleri. Different body weight of male and
female X. helleri was selected. They are
separately subjected to estimate the rates of ammonia excretion and oxygen
consumption and thereafter the ovaries were dissected out and reproductive
performances were investigated (gonad weight, GSI and number of ova
production). Rate of ammonia excretion and oxygen consumption were inversely
related to the body weight of X. helleri. However,
the gonad weight, gonadosomatic index, number of
ova and embryo productions were positively correlated to the body weight of X.
helleri. Key words: Xiphophorus helleri, body weight, sex, ammonia excretion,
gonad weight, embryo production |

Abstract: The present
research was planned to study the Assessment of Health hazards in dye unit ,In order to assess the health status of dye workers,
a sample of 160 workers was selected from different subunits of selected dye
units. Information was drawn about the working environment and other health
aspects. Mainly physical health hazards were discussed in this study. The
results highlighted the fact that majority of respondents were suffering from
physical ailments related to lungs, eyes, skin etc. Half of the respondents
reported watering of eyes due to the gas evolved during various processes.
Exposure of toxic chemicals caused various skin and respiratory problems. Key words:

mutagenic agents on heat shock proteins of Vigna
radiate (L.) Sanjeev Kumar Singh* Singhania University, Rajasthan, India *e-mail: sksingh66@gmail.com (Received: January 18, 2013; Revised

Abstract: Proper folding of a small proportion of proteins
(e.g. the cytoskeletal proteins actin
and tubulin) requires additional assistance, which
is provided by chaperonins. Eukaryotic chaperonins called TCip lacks a
GroES-type co-chaperonin,
the last step must differ in eukaryotes. Morever,
the size of TCip limits this folding pathway to
polypeptides smaller than 55kd. As evident from results more than 12 protein
bands were detectable in the supernatant fraction of vigna
radiata variety seeds which are germinated
under normal room temperature (30°C) condition. A comparison of protein
profiles of supernatant fraction of the seeds of these varieties subjected to
mutagenic stress shows a increase in number of
protein bands in the seeds obtained after treatment with mutagenic agents
ethyl methane sulphonate (EMS) and sodium azide (NaN3). Key words: Protein
folding, Seeds, Germination, Chaperonins |

Abstract: Field
experiment was conducted to study the effect of sewage water (SW) in
combination with plant growth hormone like Gibberellin
(GA3) on yield and bio chemical parameters of wheat. Sewage water
(SW) was collected from two different channels (nala)
of Bareilly city. Results indicated an increase in yield and biochemical
parameters of wheat irrigated with 100% SW of all the three channels in
combination with GA3 compared to 50% SW+GA3 and control
(Tap water). Application of 20ppm GA3 in combination with 100% SW
showed remarkable higher content of yield and biochemical parameters compared
to 100% SW+10ppm GA3 and control. However, irrigation of wheat
with 50% SW showed decrease in both yield and biochemical parameters as
compared to 100% SW alone and in combination with GA3. Key words: Sewage
water, Gibberellin, Yield, Biochemical parameters |
