Abstract : The study was carried out to investigate the antioxidant activity of fungi isolated from soil of different areas of Punjab, India and compare their efficiency with a known antioxidant, ascorbic acid.The antioxidant potential of fungal extracts was quantified by DPPH and reducing power assay. Total phenolic contents were estimated using Folins-Ciocalteau (FC) reagent. Out of 113 fungal isolates selected, 51 were having antioxidant potential and these were further assayed quantitatively. All of these showed good activity against DPPH radical while 32 of these isolates demonstrated reducing potential also. In addition, some were equally good as ascorbic acid. The present study demonstrated potential of soil fungi to have antioxidant activity similar to plants and mushrooms. High phenolic content of fungi further highlight their significance as new sources of natural antioxidants. These fungi may provide easier set up for production and purification of natural antioxidants as compared to higher plants.

Abstract : The present study deals with the determination of extended spectrum of β -lactamase (ESBL) producing Proteus in raw milk of DoonValley. ESBL producing isolates were screened by double disc approximation test using commercially available β -lactam (Piperacillin) and β -lactam/ β -lactamase inhibitor combination (Piperacillin/Tazobactam). All isolates of Proteus sp. were reported to resistant against Methicillin and were sensitive to Piperacillin, Cephotaxime, Ceftazidime, and Cefoperazone. This indicates that all the isolates were able to produce β -lactamase in low and higher amount. This amount of β -lactamase is inactivated by Tazobactam ( β -lactamase inhibitor) and the zone of inhibition with Piperacillin/Tazobactam combination was greater as compared to Piperacillin alone. There was a significant difference (>4 mm) in zone of inhibition was reported with Piperacillin and in combination of Piperacillin and Tazobactam. Hence, the overall emergence of β -lactamase producing Proteus sp. in raw milk of Dehradun City was 100%, which is an alarming situation for public health and needs serious concern.

Abstract : In the present investigation, total four isolates of Lactobacillus speciesi.e. L. casei, L. helveticus, L. brevis and L. fermentum were examined for the cell surface hydrophobicity by bacterial adherence to hydrocarbons assay in LAPTg broth and hydrophobicity was calculated as percentage decrease in Optical Density at 600 nm. The general range of hydrophobicity in Lactobacilli was found in between 6-73%. Remarkably, L. helveticus and L. fermentum showed 73% hydrophobicity in xylene. Higher value of hydrophobicity could point toward a better ability of lactobacilli to adhere to epithelial cells. The outcome of present study concludes that L. helveticus and L. fermentum have good adhesive properties which may help them to adhere to surface epithelium of host cell and further screening with other probiotic attributes could be designated as probiotics.

Abstract : Zooplanktonic analysis of Surinsar lake, Jammu, during the year 2002-2004, has shown the presence of fifty one species of protozoans belonging to three classes viz. Sarcodina (32 spp), Ciliata (16 spp.) and Mastigophora (3 spp.). Quantitatively, during the year 2002-03, there was dominance of Sarcodina followed by Ciliata and Mastigophra. In the subsequent year viz. 2003-04, the order of quantitative dominance has been observed as Ciliata> Sarcodina and> Mastigophora. Coefficient of correlation(r) of protozoans with various physico-chemical parameters has generally shown insignificant results. The calculated value of ANOVA of various protozoan classes was significant and the means of various classes differed significantly among themselves indicating their significant contribution to total protozoan population.Keywords : Lake, Zooplankton, Protozoa, Correlation, Diversity Index

Abstract : The present paper deals with the monthly variations of physico-chemical characteristics of western Yamuna canal water, Yamunanagar which is polluted with industrial effluents and domestic sewage. Three sampling points i.e. station-1: Upstream of the river; station-2: Point of influx of industrial effluents and domestic sewage; Station-3: About 6 kms downstream from station 2 were selected for the investigation. Studies revealed high values of turbidity, conductivity, free CO2 , alkalinity, calcium, hardness, magnesium, chloride, orthophosphate, phosphate, sulphate and ammonia and low values of DO at station-2. The differences in various parameters were statistically significant (P<0.05) when compared from upstream and downstream stretches of the river particularly in summer. DO and BOD were found to be two important parameters which showed strong correlation with other parameters and hence can serve as good indices of river water quality. Water Quality index designated station-1 as highly polluted and station-2 and 3 as severely polluted. Thus the hydro biological conditions were not congenial/ optimum for the survival/ production of sensitive fish fauna, therefore, proper and efficient treatment of the effluents and sewage should be carried out before discharging these into the canal.

Abstract : The present study is based on the process development for colouring of silk yarns with Dhavdi flowers using selected mordants to study its effects on colour fastness properties and optimization of different extraction conditions, duration and concentration for better dye and its shades. The results revealed that aqueous medium was suitable for extraction of dye from pink petals of Dhavdi flowers for one hour. The shades of midbuff, sand stone ,coffee and olive green brown were obtained by taking 4 g dried powder of dhavdi dye for dyeing 1 gram of silk material for 45 minutes. All the four mordants were found suitable for application on silk, 10 % of alum, 3 % of chrome, 2 % of copper sulphate and 3% ferrous sulphate were found to produce best shades on silk material. Post mordanting had resulted in darker shades in all the mordant. Simultaneous mordanting method was found best in case of chrome mordant. Excellent to outstanding fastness to sunlight was found in all mordanted samples. There was absolutely no staining in washed samples. Colour change was not found in the samples subjected to crocking in both dry and wet conditions except in case of ferrous mordanted samples,. The colour was stable as shown by their higher resistance towards acidic and alkaline perspiration. Hence, the dye obtained from Dhavdi flowers proved to be extremely good and can be recommended for dyeing silk fabric.

Abstract : Quantitative and qualitative variations in microscopic plant organic matter assemblages and its preservation state in deltaic channel deposits of Mahanadi River was correlated with the depositional environment in the ecosystem in order to prepare a modern analogue for use in palaeo environment studies. For this, palynological and palynofacies study was carried out in 57 surface sediment samples from Birupa river System, Kathjodi-Debi River system and Kuakhai River System constituting Upper, Middle and Lower Deltaic part of Mahanadi river. The apex of the delta shows dominance of Spirogyra algae indicating high nutrient, low energy shallow ecosystem during most of the year and recharged only during monsoons. The depositional environment is anoxic to dysoxic in the central and south-eastern part of the Middle Deltaic Plain (MDP) and Lower Deltaic Plain (LDP) indicated by high percentage of nearby palynomorphs, Particulate Organic Matter (POM) and algal or fungal spores. The northern part of the delta show high POM preservation only in the estuarine area in LDP but high Amorphous Organic Matter (MOA) in MDP. The sediment here is deposited under dysoxic to oxic fluvial conditions. Thus, the monsoon intensity, direction of fluvial discharge, and the landward extent of sea water incursion through river mouths inducing bottom water salinity play an important role in defining the magnitude of POM and its preservation in the shallow Mahanadi deltaic ecosystem.

Abstract : During present investigation, among the six wheat genotypes tested against six isolates of Bipolaris sorokiniana, the genotype BOW‘S’ showed resistance response against three isolates, namely, BS-D-1, BS-DWR-K-2 and BS-K-4, whereas moderately resistance response against remaining 3 isolates i.e. BS-F-3, BS-P-5 and BS-V-6.The genotype A-9-30-1 showed almost highly susceptible response against each isolate except BS-D-1 which exhibited susceptible reaction on this genotype. Thus, it is clear that genotype BOW ‘S’ has broad genetic base for resistance, whereas genotype A-9-30-1 has no gene for resistance against these six isolates tested. Remaining five genotypes showed varying response, ranging from highly susceptible, susceptible, moderately susceptible, moderately resistant and resistant against various isolates of B. Sorokiniana tested.

Abstract : The cephalo-thoracic musculature of the fifth instar larva of Bombyx mori comprises distinct groups of segmental muscle bands arranged in a stereotyped pattern. It includes dorsal, ventral, tergopleural, tergocoxal, lateral intersegmental, pleurosternal, sternocoxal, pleurocoxal and spiracular muscles. The cephalothoracic segments are innervated by the nerves of brain, suboesophageal ganglion (SG) and three thoracic ganglia (TG1, TG2, TG3).The brain gives nerves for compound eyes, antennae, labrum, frontal ganglion and the integument in the head. The SG, TG1,TG2,and TG3 give out a pair of lateral segmental nerves each, called the dorsal (DN) and ventral (VN) nerves. The DN of SG innervates muscles in the cephalic region, while its VN innervates muscles in the prothorax. The DN of thoracic ganglia innervates muscles in the dorsal, lateral and ventral regions of the hemi-segment while the VN innervates muscles in the ventral region. The innervation pattern indicates the presence of mixed nerves and multiple innervations that facilitate coordinated body movements and locomotion.

Abstract : The gross organisation of abdominal musculature and its innervation by segmental ganglionic nerves were studied in the fifth instar larva of Bombyx mori. The musculature comprises dorsal, ventral and lateral groups of muscles, represented as external and internal layers. The dorsal group includes musculi dorsales interni mediales (DIM), musculi dorsales externi mediales (DEM), musculi dorsales interni laterals (DIL) and musculi dorsales externi laterales (DEL). The ventral group includes musculi ventrales interni mediales (VIM), musculi ventrales externi mediales (VEM), musculi ventrales interni laterales (VIL) and musculi ventrales externi laterales (VEL). The lateral group is represented by musculi laterales interni (LI) and musculi laterales externi (LE). The abdominal muscles are innervated by the dorsal (DN) and ventral (VN) nerves of abdominal ganglia. The DN innervates ventral internal, lateral internal and both dorsal external and internal muscles, while the VN innervates ventral external and lateral muscles. The sensory branches of DN and VN innervate the body wall in the dorsal and ventral regions respectively with a sort of overlapping in the lateral region. The neuromuscular integration and intersegmental coordination in the abdominal region is discussed with reference to locomotion in the silkworm larva.

Abstract : A total of 1,020 poultry birds belonging to twelve different localities of Jaunpur district were surveyed during May 2006 to April 2007 to record the prevalence rate of Eomenacanthus stramineus. Prevalence of E. stramineus was noted more or less similar in both the sexes (Male – 38% and Female – 39%). Maximum birds bore very low infestation (32%) while only 7% birds exhibited very heavily infestation. Host sex, feather colour and locality had negligible effect on prevalence rate. However, prevalence rate remained slightly higher on birds with poor plumage/health. Significant positive correlation existed between mean monthly prevalence rate and mean monthly temperature as well as photoperiod. Mean monthly incidence rate were recorded higher during summer (May and June) as compared to winter months.

Abstract : Periodic fortnightly visits from June, 2007 to May, 2008 in Beer-Sonty reserve forest and surrounding agricultural fields indicated incidences of damage to various crops and many herbs, shrubs and trees by Nilgai. The opinion survey of the 208 inhabitants including 166 farmers/farm labourers and 42 forest officials/forest labourers in and around Beer-Sonty reserve forest also revealed that 74.52% of the contacted persons reported significant damage by Nilgai to agricultural crops and herbs. As far as the distribution of Nilgai is concerned, 94.72% interviewees reported random distribution while 5.28% interviewees reported non-random distribution. One year fortnightly survey revealed minimum of one to a maximum of four Nilgai sightings/visit with a minimum of one individual to a maximum of 11 individuals per sighting. Most of the times, males were sighted singly or in mixed herds, whereas, herds comprising 2-11 individuals in different sightings included female(s) with calves or mixed herds. Opinion survey has also indicated herds comprising 1-10, 10-20 and more than 20 individuals by 60.10%, 30.77% and 9.13% interviewees. During regular periodic visits of the study area and surrounding fields, farmers were found using various means such as fencing, fire, night-light, sound efforts and effigy models to check the activity of Nilgai in their agricultural fields.

Abstract : The use of language is one of the most vital traits that distinguish human from other species. The gene FOXP2 (fork head box P2) is relevant to the human ability to develop language. FOXP2 is situated on human chromosome 7q31, and its major splice form encodes a protein of 715 amino acids. It contains a glutamine rich region consisting of two adjacent polyglutamine tracts, encoded by mixtures of CAG and CAA repeats. Two functional copy of FOXP2 seem to be required for acquisition of normal language in human. The chimpanzee, gorilla and the rhesus macaque FOXP2 proteins are all identical to each other and carry only one difference from the mouse and two differences from the human protein, whereas the orangutan two differences from the mouse and three from humans. This gene is also important on particular aspects of cognition awareness or grammatical processing.

Abstract : Histochemical examination of fingerlings and adults of freshwater teleost Oreochromis mossambicus (Trewavas) exposed to sublethal concentration of HgCl2 (0.15 mg/l) for 30 days revealed considerable uptake of mercury by their respective intestines. Simultaneous co-administration of essential phospholipids (EPL) along with food to the fishes, significantly suppressed mercury uptake by the intestinal tissues, except the goblet cells which were still loaded with Hg in both stages. Due to accumulated mercury visible histopathological damage was seen in muscle layers, lamina propria and basement membrane of columnar cells. No noticeable damage in intestine was seen, when EPL was simultaneously fed to fishes along with HgCl2 exposure. Results suggest that EPL plays prophylactic role against metal uptake and structural damage in fish intestine exposed to inorganic mercury.

Abstract : The present paper deals with the RAPD-PCR based genomic characterization of Culex quinquefasciatus Say which is a major vector of filariasis in several parts of the Indian subcontinent. One population of the test organism used in the study was procured from Goa (pop.A) while the other (pop.B) was collected from a village Nadasahib (20 kms from Chandigarh). The RAPD-PCR amplification of whole body homogenate of freshly hatched individual specimens was carried out by using three random primers: primer I- 5’- GTCCCGACGA – 3’; primer II- 5’ – TGATCCCTGG – 3’ and primer III- 5’- GTGACGTAGG – 3’. Primer I produced 5 distinct bands from the DNA of pop. A, whose base composition ranged from 200-1000 bp. Likewise, 7 bands ranging from 130-750 bp and 4 bands ranging from 270-950 bp were generated with primers II and III respectively. In case of pop.B, a total of 8 bands ranging from 200-1000 bp were generated with primer I. Similarly, a total of 6 bands ranging from 250-900 bp with primer II and 4 bands ranging from 180-950 bp with primer III were produced. Based on the band sharing coefficient and the application of Nearest Neighbour Joining (NJ) analysis it was found that primer I was more suitable for detecting genomic differences at the species and generic levels while primer II was ideal for detecting variations in the number of bp in RAPD generated bands among different populations of Cx. Quinquefasciatus.

Abstract : The present study aims to identify the groundwater contamination problem in villages located in the close vicinity of Gajraula industrial area at Gajraula (U.P.), India. Ground water samples were collected from different villages at the depth of 40 and 120 feet from earth’s surface layer. Analytical techniques as described in the standard methods for examination of water and waste water were adopted for physico-chemical analysis of ground water samples and the results compared with the standards given by WHO and BIS guidelines for drinking water. Water quality index was calculated for quality standard of groundwater for drinking purposes. The present investigation revealed that the water quality is moderately degraded due to high range of seven water quality parameters such as Temperature (18.33-32.360C), conductivity (925.45-1399.59 µmho/cm), TDS (610.80-923.73 mgL-1), Alkalinity (260.17-339.83 mgL-1), Ca-Hardness (129.68-181.17 mgL-1), Mg-Hardness (94.07-113.50 mgL-1) and COD (13.99-25.62 mgL-1). The water quality index (WQI) also indicated the all the water quality rating comes under the standard marginal values (45-64) i.e. water quality is frequently threatened or impaired and conditions usually depart from natural or desirable levels.

Biochemical and spectroscopic changes in phycobiliproteins of the protein-rich Cyanobacterium, Spirulina fusiformis induced by UV-B radiation
Department f Botany, Thakur Ram Multiple Campus, Birgunj, Tribhuvan University, Nepal
Abstract : The present study indicated that the Increase in UV-B exposure (312.67 nm, 2.5 Wm-2) to Spirulina fusiformis, a highly protein-rich (60-71%) helically coiled, unicellular, polymorphous cyanobacterium not only bleached phycocyanin (PC) but also decreased its content Absorption spectra of UV-B treated culture showed significant decline in the absorbance at the peak 620 nm indicating the presence of PC. The absorbance decreased by increasing UV-B exposure. One hour simultaneous UV-B+PAR (Photosynthetic Active Radiation) exposure protected 33 percent damage of phycocyanin.

Abstract : Herbal drugs have been used as remedies for the treatment of large number of humans, ailments since ancient times as the traditional medicine system; India has a glorious past, having first documented record of fully developed medical science known as Ayurveda written by several ancient Rishi’s. Major groups of indigenous system of medicine are based on herbal drugs. A survey made by WHO indicated that about 80% of the world population relies on herbal drugs. Herbal drugs are becoming more popularized and important even in the developed nations with hope of their non-toxicity and may play a role of substitute to overcome the problems of multi-drug resistant pathogens. Cultivation of drug plants has been started in large scale without considering the land quality and in certain cases irrigation with waste water. Application of different fungicides, pesticides in that specific field or in neighboring fields may be directly deposited superficially or may be absorbed by the plant system. Therefore in the present situation possibilities of the Asian herbal drugs, contaminated with large number of toxic components cannot be ignored which may severely hurt human life in place of healing or curing.These contaminants may be either alone or in combination and may be originated intrinsically, extrinsically and deliberately. Certain contaminants may be highly toxic and may cause severe adverse effect in the human system. Some of the important contaminants are the heavy metals like lead, arsenic, cadmium, mercury, copper and pesticides. Adulteration of modern drugs to enhance drug potency and heterogenous microbial population including human pathogens may contaminate both raw and powdered herbal drugs. Among these contaminants, microbial contamination seems more severe and may be due to their dual action on the drug i.e. utilization of medicinally important chemical components as nutrients and in certain cases by producing certain mycotoxins, which may be even carcinogenic under certain conditions. Critical evaluation of both raw and powdered herbal drugs for contaminants is the urgent need of the time in order to provide safety measures in herbal healthcare medicine.
