Multiplication and spore production of three microsporidia viz., Nosema bombycis, Nosema sp. 1 and Nosema sp. 2 in fifth instar larval tissues of silkworm, Bombyx mori L. in two seasons with distinct temperature regimes were studied. Nosema sp. 2 produced significantly (P < 0.01) higher number of spores in various tissues. Among the tissues, spore production was highest in silk gland, followed by fat body and gut. Spore production was significantly (P < 0.01) higher in season-II (Average temperature $29.4{\pm}1.1^{\circ}C$). Maximum spore production was observed 25 days post inoculation (p. i.) in season-I (Average temperature $18.9{\pm}1.1^{\circ}C$), whereas in season-II, it was 14 days p. i. In season-I, spore production was low up to 21 days p. i., then increased sharply. In season-II, there was a steady increase in spore production. The results indicate that the microsporidian multiplication is tissue specific and extremely sensitive to temperature at which the host is reared. It also reveals that, silk gland, fat body and gut are the most appropriate tissues for microscopic identification of microsporidia in the larval stage.

Impact of microsporidian infection and season on reproductive potential of Bombyx mori L. was investigated in the laboratory. Microsporidian infection significantly (P<0.01) reduced fecundity and hatching and increased sterility and mortality of eggs. Among the microsporidia, Nosema sp. 2 infected silkworm produced eggs with least fecundity and hatching percent as well as highest dead and sterile eggs followed by Nosema sp. 1 and N. bombycis. Microsporidia, in general, significantly reduced fecundity and hatching percent of eggs and increased number of dead and sterile eggs in all the three seasons except N. bombycis in July - August (S3) and Nosema sp. 2 in January February (S1). Since, seed production is the anchor sheet of mulberry sericulture, coefficient of egg lying is considered as an important aspect and the industry quite often facing shortage of disease free layings. The present study indicates that B. mori is more susceptible to microsporidia during S2 followed by S3 and S1 and Nosema sp2. is most virulent followed by Nosema spl. and N. bombycis.
Antisteroidogenic activity of Raphanus sativus seed extract in female albino mice
Haldar, P.K.,Mazumder, U.K.,Bhattacharya, Sanjib,Manikandan, L.,Bhattacharya, Siladitya Kyung Hee Oriental Medicine Research Center 2009 Oriental pharmacy and experimental medicine Vol.9 No.4
The defatted methanol extract of Raphanus sativus Linn. (Cruciferae) seed (MERS) was evaluated for its antisteroidogenic potential in mature female Swiss albino mice. The methanol extract at the doses of 100 and 200 mg/kg body weight significantly elevated the levels of cholesterol and ascorbic acid contents which serve as a precursor for the synthesis of steroid hormones in ovaries. The extract also significantly inhibited glucose-6-phosphate dehydrogenase and ${\Delta}^5-3{\beta}$-hydroxy steroid dehydrogenase, the two key enzymes involved in ovarian steroidogenesis. Hence the extract (MERS) exhibited significant antisteroidogenic activity.
APPLICATION OF DOUBLE DECOMPOSITION TO PULSATILE FLOW
Mamaloukas, C.,Haldar, K.,Mazumdar, H.P. 한국전산응용수학회 2002 Journal of applied mathematics & informatics Vol.10 No.1
The present investigation deals with the pulsatile flow of incompressible viscous fluid through a circular rigid tube provided with constriction. The method applied here is the Decomposition Method, which has been developed by George Adomian [3]. The advantages of this method are the avoidance of simplifications and restrictions, which change the non-linear problem to mathematically tractable one, whose solution is not consistent with physical solution. Theoretically results, such as, wall shear stress and axial velocity component, have been obtained and the graphical solutions of these theoretical results have been shown in the figures.

The plant Indigofera aspalathoides are used by a large number of tribes in India for the treatment of various hepatic disorder. The methanol extract of Indigofera aspalathoides (MEIA) was evaluated for its effect on carbontetrachloride $(CCl_{4})$ induced liver damage. Biochemical parameters such as serum glutamine oxaloacetate trasaminase (SGOT), serum glutamine pyruvate transaminase (SGPT), serum alkaline phosphatase (ALP), total serum protein (TP), thiobarbituric acid reactive substances (TBRS) and glutathione content of the liver were estimated to assess liver function and metabolism. Biochemical observations suggest that methanol extract of Indigofera aspalathoides (MEIA) significantly restored the liver function and metabolism towards normal condition in $CCl_{4}$-induced hepatic damage.

In present study evaluate the analgesic and anti-inflammatory activity of the compound obtained from the petroleum ether (40 - 60$^{\circ}C$) extract of the fruits from Dregea volubilis in Swiss albino mice and in Wister albino rats respectively. Dried and crushed fruits of Dregea volubilis were extracted by petroleum ether (40 - 60$^{\circ}C$), the proper solvent system was developed by TLC and subjected to column chromatography for obtaining the pure compound/s. IR, MASS, NMR (PMR, C13 NMR and DEPT) spectroscopic analysis were done to elucidate the structure of the compound/s. The petroleum ether (40 - 60$^{\circ}C$) extract of the fruits of Dregea volubilis led to isolation of a pentacyclic triterpenoid designated as taraxerone and characterized as D- friedoolean- 14- en, 3 one. Taraxerone had been screened for analgesic activity in Swiss albino mice and anti-inflammatory activity in Wister albino rats at the dose of 5 mg/kg body weight orally and exhibit significant analgesic and anti-inflammatory properties.

Since the time immemorial, medicinal plants and herbal medicines have always presented to us a wide range of curative techniques that has paved our way towards modernised medical resources. The present article reviews on one of such medicinal plants, scientifically recognised to be Dregea volubilis (L. f.) Benth. belonging to the family Asclepiadaceae. Literature survey was carried out by using Google, Scholar Google, Scopus and Pub-Med. The scientific journal articles found on the internet for last two decades were considered and pharmacognostic, phytochemical and pharmacological studies on Dregea volubilis have been compiled. Almost every part of this plant has been phytochemically screened along with profound pharmacological studies especially on its leaves and fruits that have revealed immense scope for this plant to be applied to advanced drug development studies pertaining to a wide range of disorders. The present review article collates the published researches carried out globally exploring the possible therapeutic potentialities of Dregea volubilis. Relevant research in this field could lead to development of a potentially useful therapeutic agent from this plant.
