Abstract
11525 Background: Glioblastoma multiforme constitutes 40% of primary brain tumors. Multicentric Glioblastoma multiforme is rare about 3%.No definite guidelines is available in literature for management of these tumors. Methods: All Multicentric Glioblastoma multiforme were analyzed retrospectively from Jan 2003 to July 2005 for clinical behavior and response to chemoradiotharpy. Either Temozolamide or Carboplatin or Paclitaxel is used concurrently with radiation. Radiation dose 60 Gy/30 fractions over 6 weeks by bilateral parallel opposed fields was delivered using Cobalt-60 machine. Results: 27 cases were found, Male: Female 24:3, KPS 60 [40–70], Majority of them are symptomatic for 4 months, main symptoms were seizures, headache, vomiting, neurological deficite. 89% of them underwent one form of other surgical intervention. 11% were diagnosed on basis of radiological findings. 85% were supratentorial, 15% were both supra and infratentorial, one of which had spinal cord lesion. 6 [22%] patients did not receive any treatment. Among 21 patients 4 were treated only with radiotherapy, 17 with concurrent Chemoradiotherapy [Paclitaxel-8, Temozolamide-7 and Carboplatin-2]. 5 patients did not complete treatment. Among 16 patients only 6 came for first follow up, 5 of were concurrent Chemoradiotherapy [Temozolamide-4, Paclitaxel-l and RT alone 1]. At the end of 3 months only 2 patients with Temozolamide were alive. Conclusions: Multicentric Glioblastoma multiforme is an aggressive disease. Concurrent Chemoradiotherapy with Temozolamide has better role. No significant financial relationships to disclose.

Abstract
BACKGROUND Lung cancer is the most common cancer in the world accounting for 17.6% cancers worldwide. The AAR i n I ndian population varies f r om 0.98-15.55. The aim of t he present study was to analyze areduction in neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and III B) using Wobe Mugos E and its evaluation using micronuclei as a cytogenetic marker. Micronuclei, which are cytoplasmic fragments of DNA, have been used as a biological dosimeter to assess DNA damage. MATERIAL AND METHODS Fourty patients of locally advanced NSCLC were randomized into two study groups between 2001-2003. One group received neoadjuvant chemotherapy using Cisplatin and Etoposide. The other group received neoadjuvant chemotherapy using Cisplatin and Etoposide along with Wobe Mugos E which is a proteolytic enzyme preparation. A study of micronuclei frequency was done pre and post chemotherapy in both groups. RESULTS Thirty eight patients were available for final evaluation. Anemia was the most common hematological toxicity observed. Nausea and vomiting were the most common non -hematological toxicity seen. Wobe Mugos E was found to reduce the incidence of leucopenia (p = 0.005), nausea (p=0.004), vomiting (p= 0.003), sensory neuropathy (p = 0.032) and treatment related depression (p= 0.005). A reduction in micronuclei was seen in patients in patients on Wobe Mugos E. (p =0.01). CONCLUSION Neo-adjuvant chemotherapy related acute toxicity is a major problem in patients with advanced lung cancer. A reduction in micronuclei frequency shows Wobe Mugos E to be effective in reducing chemotherapy related acute toxicity.

Abstract
Functionally, the innate immune system of immature chickens is inefficient during the first week posthatch. This immunological inefficiency enables pathogens such as Salmonella enterica serovar Enteritidis (SE) to invade and colonize the visceral organs of immature chickens. The objective of this study was to evaluate the effect of purified beta-glucan as an immunomodulator of the innate immune response. beta-glucan, as a feed additive, significantly provided protection against SE organ invasion in young chickens (P<0.05). The functional efficiency of heterophils isolated from neonatal chickens fed a beta-glucan ration was significantly (P<0.05) up-regulated when compared to heterophils isolated from chickens fed a control ration as determined with an array of functional assays. Phagocytosis, bactericidal killing, and oxidative burst were significantly increased in heterophils isolated from chickens fed the purified beta-glucan ration (P<0.05). To our knowledge, this is the first report of a purified beta-glucan feed additive significantly decreasing the incidence of SE organ invasion in immature chickens and up-regulating the functional abilities of heterophils isolated from immature chickens against an invading pathogen, SE.

Abstract
The use of Bayesian Network methods to recover transcriptional regulatory networks from static microarray data is an active area of bioinformatics research. However, early work in this area lacked realistic analysis of the effects of data set size on learning performance and ignored the potentially immense benefits of using prior biological knowledge. More recent work which has utilized such information has tended to focus on qualitative descriptions of the results. In this paper, we construct a detailed, realistic model for glucose homeostasis and use this model to generate static, synthetic gene expression data. We then use a Bayesian Network method to reconstruct this genetic network from the synthetic microarray data utilizing various amounts and types of prior knowledge. By quantitatively analyzing the effects of data set size and the incorporation of different types of prior biological knowledge on our ability to reconstruct the original network, we show that characteristic portions of genetic networks can be reconstructed from microarray data. Incorporating prior knowledge into the learning scheme greatly reduces the data required, allowing these reverse engineering techniques to be used to learn regulatory interactions from microarray data sets of realistic size.

Abstract
PlasmoDB (http://PlasmoDB.org) is the official database of the Plasmodium falciparum genome sequencing consortium. This resource incorporates the recently completed P. falciparum genome sequence and annotation, as well as draft sequence and annotation emerging from other Plasmodium sequencing projects. PlasmoDB currently houses information from five parasite species and provides tools for intra- and inter-species comparisons. Sequence information is integrated with other genomic-scale data emerging from the Plasmodium research community, including gene expression analysis from EST, SAGE and microarray projects and proteomics studies. The relational schema used to build PlasmoDB, GUS (Genomics Unified Schema) employs a highly structured format to accommodate the diverse data types generated by sequence and expression projects. A variety of tools allow researchers to formulate complex, biologically-based, queries of the database. A stand-alone version of the database is also available on CD-ROM (P. falciparum GenePlot), facilitating access to the data in situations where internet access is difficult (e.g. by malaria researchers working in the field). The goal of PlasmoDB is to facilitate utilization of the vast quantities of genomic-scale data produced by the global malaria research community. The software used to develop PlasmoDB has been used to create a second Apicomplexan parasite genome database, ToxoDB (http://ToxoDB.org).

Abstract
Kala azar continues to be a medical problem in India and with the increase in incidence of HIV Infection it is likely that kala azar will be encountered more frequently and in its atypical forms. To aid diagnosis, several immunological tests are now available and they are more sensitive and specific than the aldehyde test. Like many other diseases today, the treatment of kala azar is hampered by drug resistance. Newer drugs are available and so are new delivery systems. Kala azar develops frequently in the HIV infected person before development of AIDS. The presentation is atypical and leishmanial species other than L. donovani may also be the infecting agents. A combination of sandfly control, detection and treatment of patients and prevention of drug resistance continues to the ideal approach for the control of the disease.

Abstract
Six-week-old tobacco plants (Nicotiana tabacum L., cv. SR-1) were fumigated with different, but defined and realistic combinations of NO(2), automobile exhaust and ozone for two days. To determine the effect of an additional environmental stress during exposure, plants were either wounded mechanically or treated with salicylic acid to simulate pathogen attack. The steady-state mRNA levels of genes encoding the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcS), chlorophyll a/b-binding protein (cab) and a 10 kDa protein of the water-evolving complex of photosystem II (ST-LS1) were probed in Northern analysis. Our results clearly show a decline of the mRNA levels for all three photosynthesis genes under automobile exhaust and/or ozone fumigation. Wounding and also elicitor treatment enhance this effect. In contrast, exposure to NO(2) either increased the transcription level of all three genes, or counteracted the negative effect of automobile exhaust and ozone on their expression. At this time no major changes in the concentrations of the corresponding proteins could be detected by Western blot analyses. These results are discussed in the present paper.

Abstract
The expression of defence genes was monitored by RNA blot analyses in tobacco plants (Nicotiana tabacum cv. SR-1) treated with various air pollutants at realistic concentrations that prevail in urban areas. Six-week-old plants responded with an increase in the steady-state mRNA levels of phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), chitinase and beta-1,3-glucanase, when exposed to defined and subnecrotic concentrations of automobile exhaust and/or ozone over a period of 48 h. An enhanced expression of genes encoding mitochondrial and cytosolic superoxide dismutases suggested that air pollutants induced considerable oxidative stress. Moreover, wounding or elicitor treatment of plants already exposed to automobile exhaust and/or ozone additionally increased the expression of the above defence genes, but not so in NO(2). Since the main difference between NO(2) and exhaust gas is the absence of the hydrocarbon compounds in the former, we regard hydrocarbons as favourite candidates for the toxic effect of exhaust gas, and they possibly act by generating an enhanced oxidative stress.
