Title: Anti-inflammatory, analgesic and antioxidant potential of the stem bark of Amra (Spondias mangifera Willd.) Authors: Sachan, Nikhil K; Arif, Muhammad; Zaman, M K; Kumar, Yatindra Abstract: The anti-inflammatory and analgesic activities of ethyl acetate (EAFSM) and n-butanol (NBFSM) fractions of alcoholic extract of S. mangifera bark were evaluated by using carrageenan induced rat paw edema and by tail-flick method in rats. The radical scavenging activity of ethanolic extract, aqueous extract and fractions was determined by using DPPH radical scavenging capacity assay. Two fractions of the alcoholic extract, EAFSM and NBFSM at the dose of 75, 150 & 300 mg/kg b.w. orally after overnight fasting, showed significant reduction in paw volume when compared with respective control group of carrageenan challenge. Different doses of extract fractions also showed significant prolongation of tail-flick latency of rat (P<0.01). Different concentrations of alcoholic, aqueous extracts and fractions of alcoholic extract showed significant free radical scavenging capacity against DPPH generated free radicals. Page(s): 211-218

Title: Participation of women in forestry and livestock activities in the arid region of India Authors: Bohra, N K; Kumar, Pramod; Mishra, D K; Limba, N.K.; Mutha, Sarita Abstract: A study on the participation on the women in forestry and livestock activities in the arid region of India was undertaken with special reference to nine villages of Jaisalmer district in Western Rajasthan. Households were selected on random sampling method. The survey was carried out with an objective to study women participation in agricultural, forestry, livestock, economic activities and household activities. Study reveals that women participation in livestock activities is between 60 and 80% whereas, in household activities contribution is almost 100 per cent. It was found that financial matters (i.e marketing and procurement of seeds / animals etc) are solely managed by the male members of the society. The research paper deals with the contribution of women in agricultural, forestry and household activities. Page(s): 207-210

Title: Study of effect of photoperiod on the movement of food through the gut of Bombyx mori Linn. Bivoltine Larvae. Authors: Mishra, A B Abstract: The effect of photoperiod on the passage of food through different regions of gut in silkworm (Bombyx mori Linn.) Bivoltine larvae has been studied in detail. Variation in the photoperiod influences the rate of movement of food passing through the gut. Food passage fasten during dark phase in comparison to the light condition in different regions of the gut. Similarly the rate of egestion of excretory pellet is also influenced by light in all larval stages (III^rd, IV^th & V^th ). Page(s): 203-206

Role of brassinosteroids in crop productivity

Title: Role of brassinosteroids in crop productivity Authors: Nagar, P K Abstract: Brassinosteroids (BRs) are a new group of plant hormones which play an important role in various phases of plant growth and development. This group of compounds regulate various processes in plants like seed germination, rhizogenesis, flower and fruit development, senescence and abscission. This group of plant steroids includes about 70 compounds having structural similarities with animals, insects and human steroid hormones. In recent years through the use of molecular genetics and genetic studies its role has clearly been established in plant growth and development. About 40 years back the first BR was isolated from pollens of Brassica rapa and since then several practical applications of BR in agriculture uses have been reported. But due to high cost of production its commercial application was hampered. However, in recent years, due to increasing availability of many of its formulations in countries like Russia, China, Cuba and India has opened a new door in its agricultural applications. Besides, BRs also protect the plants from various biotic and abiotic stresses. The present article discusses the importance of BRs in enhancing crop productivity. Page(s): 197-202
