Abstract: Scylla serrata (Crustacea: Decapoda) is a
potential aqua crop and economically important edible species, widely distributed
in the intertidal mud flat of Sundarbans Biosphere
Reserves of West Bengal, India. S. serrata
is considered as one of the large groups of crab in Sundarbans
mangrove swamp. Crabs occupy diverse habitats and their strategy of survival
is correlated to multidimensional immune responses and crabs including S. serrata inhabiting in biounsafe
environment are under constant threat of physiological stress caused by
diverse xenobiotics including arsenic. A series of
polyclonal antisera were raised in rabbit against
crab hemocytes and murine
lymphocytes. For agglutination response control hemocytes
and hemocyte expressed to 1 ppm expressed almost
similar reactivity against antihemocyte sera.
However exposure to 2 and 3 ppm of sodium arsenite resulted a shift from the control data is indicative of
arsenic induced alteration of hemocyte surface.
Gradual increase of concentration of sodium arsenite
in the medium of the treatment sets resulted a
progressive shift of agglutination response from the control sets of hemocytes reacted with murine antilymphocyte sera.Maximum
equivalence zone of agglutination of murine
lymphocytes and hemocytes indicated a possible
sharing of epitopes between two phylogenetically
distinct species. Shift in agglutination reaction under exposure of sodium arsenite expressed a possible modulation in antisera mediated hemocyte
agglutination reaction of S.serrata.
Situation may lead to a possible alteration of immune status. Chronic arsenic
exposure is indicative to steady decline of S. serrata
in natural habitat of Sundarbans. Key words:

Abstract: The
present investigation was carried out to evaluate the effect of alcoholic
fruit extract of Momordica cochinchinensis on serum protein profile of albino
rat. Alcoholic fruit extract of Momordica
cochinchinensis (200 mg kg-1body
weight) has been given orally to albino rats for the period of 7,15,30,45 and
60 days respectively.Results showed a significant
(p<0.01) increase in serum total protein, albumin and total globulins and
non-significant increase in A/G ratio in rats. Increase in serum protein
after the administration of alcoholic extract of Momordica
cochinchinensis in albino rates was due to
increase in number of m-RNA molecule and their attachment to the ribosome’s
and thus increase protein anabolism. Key words: Momordica cochinchinensis, Serum protein profile |

Abstract: Genetically
pure seeds of Pisum sativum
variety pusa harbhajan
were inoculated under aseptic conditions on revised murashige
and Skoog’s medium supplemented with 1 ppm of 2,4-D
and 1% agar. Four weeks old cultures were exposed to gamma radiations for
three hr in replicates of five. Dose of radiations selected for treatment
were 2000, 2400, 2800 and 3200 R. Cultures of different dose were harvested
after four weeks, dried and subjected to extraction for flavonoids
by well established method. Kaempferol was
identified through TLC, PTLC MP and IR spectral studies whereas quantitative
estimation was carried out using spectrophotometric
method. Maximum amount (0.10 mg g-1) was observed in the sample
treated by 2800 R, followed by sample treated by 2400 R, 3200 R (0.05 mg g-1)
and 2000 R (0.03 mg g-1). However remarkable increase in kaempferol content was observed when compared with

Abstract: The
growth characteristics of Pyricularia grisea (Cook) sacc (teleomorph ,
Magnaporthe grisea
(Hebert) Barr, the blast pathogen of more than 50graminicious hosts,
including rice and small millets,can be easily
studied on artificial medium. For this, oat meal agar medium is widely used
for in vitro culture as well as sporulation
of P. grisea, which however is quite expensive.
Therefore, a study was designed to develop and evaluate cultural
characteristics of P. grisea isolates
obtained from Eleusine coracana (finger millet) on media derived from rice
and finger millets, viz. rice leaf agar, ragi
leaf agar, and ragi flour agar. Growth
characteristics such as vegetative growth, sporulation
and production of perfect stage were recorded and compared with those
obtained on oat meal agar. Results revealed that ragi
flour media recorded better growth and sporulation
of P.grisea at 28oC and pH
7.5 than other three media. Abundant perithecia
were produced on ragi flour media at 20-220C
when compared to other media. The study revealed that ragi
flour media was the cheapest and effective medium, and a good replacement of
the expensive oatmeal agar medium for the growth, sporulation
and production of perithecia of P.grisea
under artificial conditions. Key words: Pyricularia grisea, Magnaporthe

Abstract: In the pot culture experiment different
dilutions of treated tannery effluent (T.E.) i.e. 10, 25, 50, 100 %
were selected to study the toxic effect on radish (Raphanus
sativus L.) plant. For the recovery of plant
damage, protective value of 10 and 25 ppm of certain macro (potassium) and
micro nutrient (Iron and zinc) were also used in the form of zinc sulphate (ZnSO4), potassium sulphate (K2SO4)
and iron sulphate (FeSO4) and added in
50% T.E. in separate pots. Finally the experiment was setup with the various
treatments i.e.Control (distilled water),
10% T.E., 25% T.E., 50% T.E., 100% T.E., 50% T.E.+10 ppm ZnSO4,
50% T.E.+25 ppm ZnSO4, 50% T.E.+10 ppm K2SO4,
50% T.E.+25 ppm K2SO4, 50% T.E.+10 ppm FeSO4 and 50% T.E.+25 ppm FeSO4.
The various growth parameters, pigments, enzymes’ activity, total protein,
total sugar and metals’ accumulation were analyzed in each treatment at the
end of 90th day while pigments, enzymes’
activity, total protein and total sugar contents were also observed at 45th day. The different concentrations of T.E.
showed significant increase in leaf area, fresh and dry weights at lower
concentration (< 25%) while they decreased at 50% concentration of T.E.
The pigments (chlorophyll, pheophytin and carotenoids) were decreased with
increase in concentration of T.E. The lower doses of T.E. (10% at 45 days)
slightly increased chlorophyll b, pheophytin a and
total carotenoid pigments content. The total sugar and protein contents were
also significantly decreased while catalase and peroxidase activity showed
significant increase with rise in concentrations of T.E. The concentration of
chromium was increased with increase in T.E.t
concentration in plant leaf and root, while the other elements i.e.
Zn, K, Fe were decreased with increase in T.E. concentration in both parts.
The zinc, potassium and iron sulphate treatments led to recover the damage
caused by T.E.in all parameters. The concentration of chromium was also found
to be decreased in recovery treatments in comparision
to50% T.E. treatment. Overall, in recovery treatments Zinc showed highest and
significant recovery in most of theparameters. Iron
also showed almost similar effects to the zinc while potassium showed minimum
recovery. Key words: Tannery effluent, chromium (VI), pigments,
amylase, catalase, peroxidase, sugar,
protein, metal accumulation, Raphanus sativus L. |
