Production of safe food through organic farming while maintaining soil sustainability is the crucial challenge of recent time. As such a pot experiment was conducted using animal manure (TAM), neem-cake (TNC), vermicompost (TVC), biochar (TBC) and urea (TU) with control (TC) to assess their capacity to stimulate Spinacia oleracea growth under field condition and their impact on soil fertility. Six treatments: TC, TAM, TNC, TVC, TBC, TU with three replications were used in completely randomized design (CRD). All the plant growth parameters were measured at regular interval up to maturity. Complete chemical analysis of plant tissue, amendments and soil was carried out. Nitrogen use efficiency (NUE) under different treatments was calculated at 45 and 60 days. All the treatments showed statistically significant (P ha) were found at TNC which increased respectively 132%, 258%, 450% over control and 125%, 431%, 448% over urea. TVC was the second best treatment followed by TBC for plant growth. NUE was significantly (P han any other treatments and was higher at maturity than vegetative state. TNC had lower NUE than TVC and TBC but the inherent N content was higher in TNC than TVC and TBC. Uptake of certain macro nutrients showed significant (P i.e., plant height with P (R = 0.887);leaf area with N (R = 0.957) and P (R = 0.985);dry weight with N (R = 0.996), P (R = 0.994) and K (R = 0.860). Significant (P harvest soil C and CEC content was found with all the treatments. The highest availability of N, P and S was observed under treatment TNC. For short duration crop like spinach, TNC is the best option followed by TVC as they release nutrient quickly than TBC and TAM.

A study was conducted to investigate the land-use pattern change over a period of 18 years （1988-2006） by using remote sens- ing and Geographical Information System （GIS） technologies, in the West Bhanugach Reserved Forest, a hill forest, in Sylhet Forest Divi- sion of Bangladesh, The images were processed using ERDAS Imagine software. Both supervised and unsupervised approaches were ap- plied and ground control points were collected using a GPS. Maps were prepared using GIS software. Results showed that vegetation cover drastically decreased from the year 1988 to 1996 （l 826 ha to l 714.85 ha）, but increased gradually from the year 1996 to 2006 （l 714.85 ha to l 847.83 ha） due to the initiation of co-management practice involving local communities. Change in bare land was inversely proportionate to the amount of vegetation cover changes unless any other land-uses were converted into bare land. The area of water bodies increased from the year 1988 to 1996 （307.67 ha to 379.53 ha）, but decreased from the year 1996 to 1997, then remained invariabile from the year 1997 to 2006. Some recommendations were also made for applying the RS and GIS techniques to study the land-use pattern change in the Bhanugach Reserved Forest and to create a GIS data base for the study area.

A net-house experiment was conducted to assess the impacts of different sources of biochar on growth and development of plant. Three different types of biomasses viz., cow dung, poultry manure and sewage sludge produced were used for the study. An upland leafy vegetable commonly known as kalmi (Ipomoea aquatic) was used for pot culture experiment. The biomass or biochar was applied to the soil at a rate of 5 t/ha and the pots were arranged following completely randomized design. A number of physical, chemical and physico-chemical properties of the soil, biochar, biomass and plant samples were analyzed in the laboratory. Biochar treated soils showed higher CEC than the corresponding biomass treated ones. Organic carbon in biochar treated soils was also higher. Total nitrogen contents of biomass treatments were higher than biochar treatments. Phosphorus, potassium and sulphur concentrations of the treated soils increased after harvesting. The paper discusses plant growth and agricultural crop production vis-à-vis biochar application, indicating that the materials might not exert similar positive effects as their biomass sources and thereby likely to jeopardize crop production and soil health.

Objective： To observe the efficacy and safety of cetuximab combined with chemotherapy in advanced non-small-cell lung cancer （NSCLC）, and to investigate the association of status of K-RAS gene mutation and epidermal growth factor receptor （EGFR） genotype with clinical outcome. Methods： Between Jan. 2006 and Sep. 2009, nineteen patients with advanced NSCLC received cetuximab （〉4 weeks） combined with chemotherapy in Department of Thoracic Oncology at Beijing Cancer Hospital. Response, survival and toxicity were retrospectively assessed, epidermal growth factor receptor （EGFR） protein expression was evaluated by ELISA Kit. The status of K-RAS gene mutation was tested by PCR-RFLP and EGFR gene amplification was measured by EGFR fluorescence in situ hybridization （FISH）. Results： Partial response（PR） was observed in 26.3%（5/19） of the patients and stable disease（SD） in 52.6%（10/19）. Median progression free survival（PFS） was 6 months （95% CI： 3.6-8.4）. Median overall survival （mst） and 1-year survival rate（SR） were 10.6 months （95% CI： 6.6-14.6） and 47.6%, respectively. Mild or moderate skin rash was the most common toxicity related with cetuximab. K-RAS gene mutation, EGFR protein level and amplification have little correlation with prognosis. Conclusion： Cetuximab combined with chemotherapy was tolerable and the skin rash related with cetuximab was mild to moderate. Cetuximab may prolong survival of the patients who failed to previous chemotherapy.

Paracetamol (PCM) is enlisted in the WHO model list as an essential medicine for pain and palliative care, but at overdose, it causes hepatic damage. This study was designed to assess the analgesic efficacy and hepatoprotective property of a solid dispersion (SD) loaded with PCM. A number of PCM loaded formulations (PSDs) were fabricated using silica alone or in combination with polyethylene glycol and/or na-citrate followed by in-vitro dissolution profiling. Selected PSDs with improved dissolution profile were subjected to solid-state characterization (DSC, PXRD, FTIR, and SEM), stability study along with investigation of in-vivo analgesic efficacy and effect on hepatocytes. Among these, PSD10 showed a rapid and significantly higher in-vitro drug release than pure PCM. This improvement was distinct to other PSDs also. Solid-state characterization of PSD10 authenticated the conversion of crystalline PCM to amorphous form upon formulation. Subsequent oral administration of PSD10 in Swiss albino mice showed 1.44-fold greater analgesic efficacy than pure PCM at dose 30 mg/kg. Besides, at acute toxic dose, liver histology of PSD10 mice was comparable with NC mice indicating hepatic protection upon formulation, whereas the PCM mice showed extensive hepatic necrosis which was also endorsed by significantly higher values of SGPT, SGOT, and ALP than PSD10 mice. Finally, an accelerated stability study of PSD10 performed according to the guideline of ICH noticed no remarkable deviation in its dissolution performance as well as crystalline nature. Thus, this newly developed PSD10 may be a safe and promising alternative for pain management and palliative care.

Medium-term changes in the labile nutrient pool of microbial biomass carbon (MBC) and nitrogen (MBN) resulting from organic manure application in rice (Oryza sativa L.)-based triple cropping systems have been poorly studied. Therefore, the effects of organic materials on the soil physico-chemical properties and microbial biomass in rice fields were investigated at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh, from April 2010 to December 2012. Five treatments (control, cow dung, poultry manure, rice straw, and chemical fertilizer) were laid out in a randomized complete block design with four replications. The organic residues (2 t C ha-1) were applied 7 days before transplanting and were combined with inorganic fertilizers, following integrated plant nutrition systems. This paper presents the results from the last of the five consecutive rice growing seasons. All of the organic residues increased the pH, and organic C, N, P, and K contents of the soil. However, poultry manure was more efficient in increasing soil fertility than cow dung and rice straw, resulting in a significant increase in P from 22 mg·kg-1 to 63 mg·kg-1 at crop harvest. All of the organic residues also increased the soil water holding capacity and decreased bulk density. Furthermore, poultry manure resulted in significantly higher microbial biomass C (432 mg·kg-1;P harvest, followed by cow dung and rice straw. These findings indicate that the regular application of organic residues and manures will help to enhance soil fertility and production sustainability.
