Squamous cell carcinoma of the gallbladder is rare and accounts for about 12.7% of all cases of gallbladder cancer. Pure squamous cell carcinoma is even less common with a reported incidence of 3.3%. We present a case of 72 year-old African-American woman with decreased appetite, fatigue, and weight loss associated with intermittent right upper quadrant pain for two months. Computed tomography of the abdomen revealed a mass in the gallbladder and the hepatic flexure of the colon with involvement of adjacent small bowel. On exploratory laparotomy, a mass at the dome of the gallbladder was found with local invasion of the hepatic flexure, and the proximal transverse colon. There was no obvious involvement of the duodenum, common bile duct, or the extra-hepatic biliary tree. An extended right hemicolectomy, distal small bowel resection, cholecystectomy, a wedge resection of the liver and a feeding jejunostomy, were performed. Pathologic evaluation demonstrated well to moderately differentiated squamous cell carcinoma of gallbladder without evidence of distant metastasis. The patient improved clinically and was discharged home in good condition.

Production of Biochar for Soil Application:A Comparative Study of Three Kiln Models

引用

Pedosphere 2015年第5期25卷 696-702页

Biochar has potentials for soil fertility improvement, climate change mitigation and environmental reclamation, and charred biomass can be deliberately incorporated into soil for long-term carbon stabilization and soil amendment. Many different methods have been used for biochar production ranging from laboratory to industrial scales. However, in countryside of developing countries, biomass is generally used for cooking but not charred. Biochar production techniques at farmer scale have remained poorly developed. We developed and tested biochar production kilns for farmers with a dimension of 50.8 cm × 38.1 cm （height × diameter）, using three different setups for optimizing oxygen （02） limitation and syngas circulation： airtight with no syngas circulation （Model I）, semi-airtight with external syngas circulation （Model II） and semi-airtight with internal syngas circulation （Model III）. A comparative assessment of these biochar production kiln models was made considering biochar pyrolysis time, fuel to biomass ratio, biochar to feedstock ratio and thermogravimetric index （TGI）. Among the models, the best quality biochar （TGI ---- 0.15） was obtained from Model I kiln taking the longest time for pyrolysis （12.5 h） and the highest amount of fuel wood （1.22 kg kg-1 biomass）. Model III kiln produced comparatively good quality biochar （TGI = 0.11）, but with less fuel wood requirement （0.33 kg kg-1 biomass） and shorter pyrolysis time （8.5 h）. We also tested Model III kiln in a three times larger size under two situations （steel kiln and pit kiln）. The biochar to feedstock ratio （0.38） and quality （TGI =0.14） increased slightly for the larger kilns. Quality of biochar was found to be mainly related to pyrolysis time. The costs for the biochar stove and pit kiln were US$ 65-77, while it was US$ 154 for the large size steel kiln. Model III kiln can potentially be used for both cooking and biochar production at farmer scale.

Acute and Chronic Toxicity of Thioacteamide and Alterations in Blood Cell Indices in Rats

引用

Journal of Cancer Therapy 2013年第1期4卷 251-259页

Background: Thioacetamide (TAA) has been used extensively in the development of suitable animal models of acute and chronic liver injury employing various doses, times and routes of its administration, particularly in drinking water due to its resemblance with human liver fibrosis and cirrhosis. The aim of this study was to investigate and compare hematological alteration during the acute and chronic liver inflammation. Methods: Acute Liver inflammation was induced in Wistar rats via intraperitoneal injection of thioacetamide and the animals were sacrificed 12 h after the TAA administration. Induction of chronic liver inflammation was performed by continuous administration of TAA in the drinking water (200 mg/L) during 18 weeks of experiment. After that all animals were sacrificed and Blood samples were collected for further analysis. Results: Single intra peritoneal injection of TAA (300 mg/kg B.W.) induced an acute condition with hematological changes including leukocytosis with marked neutrophilia (P = 0.0429), lymphopenia, thrombocytosis as well as increased hemoglobin concentration (P 0.05) and decline of erythrocytic count (P = 0.0009). Eighteen weeks of uninterrupted supply of TAA (200 mg/L) in drinking water lead to chronic inflammation and the hematological alterations were leucopenia (P = 0.0197) accompanied with neutropenia and thrombocytopenia. Increase in RBCs (P = 0.0073) and Hb contents was also observed with a decline of red cell indices. Conclusion: Taken together these findings we can conclude that the animals respond differently under acute and chronic inflammatory condition with TAA administration. Leukocytosis with marked neutrophilia, thrombocytosis as well as increased hemoglobin concentration and decline of erythrocytic count were observed in acute while leucopenia accompanied with neutropenia and thrombocytopenia and increase in RBCs, Hb and Hct was also observed with a decline of other red cell indices during chronic phase.
