Retz and Justicia adhatoda Linn. respectively on germination and growth of wheat ( Triticum aestivum Linn.) and pea ( Pisum sativum Linn.). Effect was assessed by recording their effects on germination and percentage growth of root and hypocotyle of test plants. However, the extent of inhibitory and stimulatory effect of extracts varied with the plant species. The extract reduced the germination of the test seeds. However, root and hypocotyle elongations of wheat and pea seedlings were significantly inhibited by the extract of studied plant parts, with the percentage of inhibition increased as the concentration of the extract increased. The observed allelopathic activity of the extract of both medicinal plants on the seed germination and seedling growth of wheat and pea was attributed to the presence of the allelopathic phytochemicals in medicinal plants. The results showed that Justicia adhatoda Linn. had strong inhibitory effect on germination as well as root and hypocotyls growth of test seeds. Phytochemical screening of both medicinal plants was also carried out by using standard methods. The extract contained alkaloid, terpenoids, flavonoids, tannins and saponins in different proportions; with more of alkaloids, flavonoids and terpenoids. J. Nat. Hist. Mus.

Congenital anomalies are associated with genetic factors (transgenes, chromosomes), environmental agents (infection, toxins, teratogens, fertilization techniques, management) or a combination of factors (Keeler et al., 1981; Newman et al., 1999). In supernumerary ectopic limb (SEC) anomaly, accessory limbs are attached to the various body regions (Fourie, 1990; Hiraga et al., 1989). These accessory limbs are usually smaller than the normal limbs and have stiff joints and sparse muscles with innervations (Pohlmeyer, 1974). Polymelia is reported from human, cattle, deer, dolphin, frog, cat, dog and poultry but is extremely rare in swine (Hiraga & Demis, 1993; Ramdan et al., 1998; Talamillo et al., 2005). Polymelia in birds is very rare. Only a few cases of polymelia in chicken are recorded from different parts of the world. A Nera black chicken ( Gallus domesticus ) with polymelia and rudimentary wing was reported from Nigeria in 2008 (Odunayo et al., 2013). A chicken with polymelia was reported from Kitam village, Sikkim, India in 2012(10 News WTSP Tampa Bay). In Egypt amputation of polymelia in a layer chicken was done in 2014 (Abu-Seida, 2014). For the first time polymelia in shakini breed chicken ( Gallus domesticus ) is recorded in Nepal. There is no previous report on such deformity in domesticated fowl in Nepal. The chicken with polymelia is ten days old and is detected in the author’s neighborhood in Pokhara valley, midwestern region of Nepal during the month of December, 2014. Physical examination of the chicken revealed well developed extra limbs consisting of the femur, tibiofibula and the phalanges which are attached to the upper region of the coccygeal area of the chicken. The limbs are smaller than the normal limbs with equal digits but are non-functional. The chicken looks normal and seems to have no problem with the supernumery limbs so far. J. Nat. Hist. Mus.

Water footprint is defined as the total volume of both indirect and the direct freshwater used for producing goods and services consumed by individuals or inhabitants of community. There are many studies regarding the direct water use but studies incorporating both direct and indirect water use is deficient. This study tries to estimate total volume of water based on the consumption pattern of different commodities by individuals of Kathmandu Metropolitan city using extended water footprint calculator. The average water footprint of individuals appears to be 1145.52 m 3 /yr. The indirect and direct water footprint appears to be 1070.82 Mm 3 /yr and 46.59 Mm 3 /yr respectively which cumulatively give the total water footprint of Kathmandu Metropolitan City of 1117.40 Mm 3 /yr. This volume is equal to 2.27 times the annual flow the River Bagmati. The indirect water footprint includes food water footprint of 1055.60 Mm 3 /yr or 2.14 times the annual flow and industrial water use of 15.22 Mm 3 /yr or 0.03 times the annual flow while the direct water footprint includes domestic water use of 46.59 Mm3/yr or 0.09 times the annual flow. In food water footprint, cereals consumption shared the highest contribution of 34.82% followed by meat consumption with share of 32.62% in total water footprint. Per capita per day water use of inhabitants appears to be 3138 liters which includes water use in food items of 2965 liters, industrial water use of 43 liters and domestic water use of 131 liters. The per capita per day domestic water use is 90 liters more than supplement of 41 liters by the water operator of Kathmandu Valley. Per capita per day domestic water use is already 5 liters more than expected improvement in water supplement of 126 liters per capita per day in 2025 after accomplishment of Melamchi water project. And, it is expected to increase further observing the rapid urbanization of Kathmandu Metropolitan City. The study showed water footprint of individuals is directly related to food consumption behavior, life style and services used therefore it is necessary to initiate water offsetting measures at individual level and water operator to find environmentally sustainable alternatives along with ongoing water project to fulfill demand.

Application of this technology opens an alternative route for mass scale production, efficient delivery of cloned plantlets and fulfils the increasing demand of local growers. An attempt was made to produce artificial seeds and their subsequent regeneration of a highly valuable medicinal orchid of Nepal i.e. Cymbidium aloifolium. Artificial seeds were obtained through encapsulation of protocorms in calcium alginate beads. Protocorms were encapsulated by using 3% sodium alginate and 0.2 M calcium chloride solution. Murashige and Skoog (MS) medium (1962) was used as the basal medium for in vitro germination and seedling development of artificial seed. In Cymbidium aloifolium , 20-25 days old in vitro grown protocorms were used for production of artificial seeds. Artificial seeds were inoculated on two different culture conditions of MS medium i.e. MS solid & MS liquid with four different treatments i.e. strength of 1.0, ½, ¼ and MS media supplemented with plant growth regulators viz. BAP (0.5 mg/l) and NAA (0.5 mg/l). Highest percentage of germination (100%) and plantlet conversion was found on hormone free full strength (1.0 MS) of MS liquid medium after 13-14 weeks of culture. Plantlets regenerated from artificial seeds with well developed shoot and root systems were successfully acclimatized in potting mixture of cocopeat, litter and sphagnum moss in a ratio 2:1:1. J.

Out of 495 children, 137 (27.68%) were found positive for one or more intestinal helminthic parasites. Ascaris lumbricoides (22.63%) showed highest prevalence rate followed by Trichuris trichiura (6.06%), Strongyloides stercoralis (1.82%), Hookworm (1.62%), Taenia sp. (1.01%), Hymenolepis nana (0.81%) and Enterobius vermicularis (0.40%). The helminthic infection was found to be almost equal in male and female children and statistically no signifi cant difference was found (χ2 = 8.31×10-6, p>0.05). Higher percentages of students were infected with single parasites than double and multiple infections. All 137 positive cases were treated with single oral dose of 400 mg albendazole. Post-treatment stool samples were collected four weeks after treatment to determine the cure rate. Stool samples were again collected 24 weeks post-treatment to study the rate of reinfection. The Cure Rates (CR) for A. lumbricoides was 61.82%, S. stercoralis was 66.67%, Taenia sp., Hookworm and E. vermicularis were 100%, T. trichiura was 44.83% and H. nana was 0.00%. The post treatment examination after 24 weeks showed that re-infection was present in A. lumbricoides (20.29%) and T. trichiura (7.69%) only. New infection was recorded for A. lumbricoides (21.74%), T. trichiura (4.72%), S. stercoralis (1.60%) and E. vermicularis (0.76%). The study showed albendazole was comparatively less effective against S. stercoralis, A. lumbricoides and T. trichiura which may be due to development of drug resistance at certain level which needs to be explored.
