Intraperitoneal Circulation and Drainage in the Dog

The patterns of dispersion and drainage of a low viscosity, oil-based contrast medium within the peritoneal cavity were examined in 12 normal dogs. Intraperitoneal injection of contrast medium was cranial or caudal and drainage was by the sump-Penrose or open peritoneal method. Radiographs were made over a 96 hour period, before and after peritoneal drainage was established. Each dog was euthanatized and necropsied. The contrast medium was dispersed throughout the peritoneal cavity 15 to 30 minutes after cranial injection and 1 to 2 hours after caudal injection. Most of the contrast medium drained within 6 hours after open peritoneal drainage and within 24 to 48 hours after sump-Penrose drainage. At necropsy, there was complete encasement of all sump-Penrose drains and partial occlusion of all open peritoneal incisions by omentum adhered to the abdominal wound edges. Peritonitis was not grossly evident, but all dogs showed histologic evidence of an acute inflammatory reaction associated with the drain or wound edge.     

Challenges in developing and implementing a decision support systems (ETÇAP) in forest management planning: a case study in Honaz and Ibradı, Turkey

Decision support systems (DSSs) are indispensable tools in preparing a forest management plan for a better combination of multiple forest values. This study attempted to develop and explain a stand-based forest management DSS (Ecosystem-based multiple-use forest planning [ETÇAP]) comprising a traditional simulation, linear programming (LP), metaheuristics and geographic information system. The model consists of five submodels; traditional management approach to handle inventory data, an empirical growth and yield model, a simulation to conceptualize management actions, a LP technique to optimize resource allocation and a simulated annealing approach to directly create a spatially feasible harvest schedule. The ETÇAP model has been implemented in a comparative two case study areas; Denizli–Honaz and Akseki–Ibrad?. Both simulation and optimization models outperformed to the traditional management plan. The periodical change of growing stock, allowable cuts, carbon sequestration and water production are used as performance indicators. The results showed that more amount of wood could be harvested over time compared to traditional level of harvesting. It could be concluded that various management strategies allowed managers to stimulate more decision options for better outputs through intertemporal trade-offs of management interventions as the model provided tools to quantify forest dynamics over time and space. Challenges exist to establish the functional relationships between forest structure and values for better quantification and integration into the management plans.     

湿地红线的确定与管理

湿地红线是国家湿地保护法律法规的另一种体现形式，是湿地管理的手段和工具，也是进行湿地评价的尺度和标准。湿地红线的制定已到了关键时期，条件已经成熟，利用目前最新的湿地调查成果，从生态系统安全、社会文化和经济三个方面进行理论指导，科学地确定湿地的数值与空间红线；同时，为了让生态红线真正发挥作用，还需要制定相配套的法律法规，建立相应的考核机制、出台相关经济政策等作为保障。     

20份欧洲型黄瓜种质资源的半致死温度与耐热性研究

为探讨不同欧洲型黄瓜种质资源对高温的适应性差异,为耐热种质资源筛选及耐热机理的深入研究提供理论和实践依据,以20份欧洲型黄瓜的叶片为材料,设置6个高温处理,以室温为对照,测定浸提液电导率值并计算相对电导率,通过拟合Logistic方程,计算半致死温度(LT50)。试验结果表明,随着温度升高,相对电导率呈"S"型曲线,且相对电导率与处理温度存在显著的直线相关关系,通过计算"S"型曲线拐点求得20份欧洲型黄瓜的半致死温度在45~51℃,其中33-2的半致死温度最高,达到50.09℃,37-1的半致死温度最低,为45.82℃。20份欧洲型黄瓜的耐高温能力由强到弱依次为33-275-232-233-111-231-209-236-276-136-137-210-135-276-211-143-235-175-132-137-1。因此,半致死温度可作为评价欧洲型黄瓜耐热性的一个可靠指标。

Investigation of biochemical and haematological side-effects of cefquinome in healthy dogs

In the present study, the effects of cefquinome, a 4th generation cephalosporin, on clinical, biochemical, haematological, and blood gas variables were investigated. Five healthy dogs were injected with cefquinome (1 mg/kg body weight, IM, daily) for 14 days. Negative effects of cefquinome on clinical, biochemical, and haematological variables were not observed, but it did change some blood gas variables.
