South Omo Administrative Zone in Ethiopia is home to 18 indigenous ethnic groups whose livelihood is vulnerable due to recurrent drought and degradation. Despite the preliminary observation showing the rich dry-forest resource base that, if sustainably managed could enhance livelihoods and biodiversity conservation, there is lack of empirical data on its current status. We conducted a study aiming at quantifying the population status of gum- and resin-bearing species in two randomly selected districts, Hamer and Bena-Tsemay. Seventy-five quadrats （35 at Hamer and 40 at Bena-Tsemay） each measuring 400 m2 were established along line transects to assess species diversity and equitability, density, frequency, dominance, importance value and population structure. We recorded a total of 27 woody species of 12 families and 14 genera. Fifteen species （9 at Hamer and 14 at Bena-Tsemay） of the genera Acacia, Boswellia, Commiphora and Sterculia, were identified as either major sources of commercial gums and resins or their adulterants. Gum- and resin-bearing species comprised 56% and 57% of species richness, 48% and 50% of total density per ha, 95% and 98% of basal area, and 64% and 56% of importance values at Hamer and Bena-Tsemay, respectively. Diversity of the entire woody species assemblage and of the gum- and resin-bearing species was slightly higher at Bena-Tsemay （H= 2.61, 1.4） than at Hamer （H＇= 2.48, 1.28）, respectively. The diversity and abundance of the resource base suggest potential for development of value-added commercialization of gum and resins to enhance livelihoods and encourage sustainable management of the forest at these study areas. We recorded, however, declining natural regeneration of most gum- and resin-bearing species, and this calls for integrated and participatory species management and landscape rehabilitation.

Glucagon-like peptide-2 exhibits protective effect on hepatic ischemia-reperfusion injury in rats

Frontiers of Medicine 2015年第3期9卷 368-373页

Glucagon-like peptide-2 （GLP-2） has potent anti-inflammatory effects and protects against experimental ischemia/reperfusion （I/R） injury in pulmonary, intestinal, and myocardial tissue. However, its protective abilities against I/R injury in the liver are unknown. We investigated the potential role of GLP-2 pretreatment on hepatic I/R injury in rats. A total of 24 rats were randomly divided into three groups （n = 8）. The first group was the control group; the second group was the vehicle-treated hepatic ischemia/reperfusion （HIR, vehicle saline-treated） group; and the third group was the GLP-2 pretreated I/R （GLP2-IR） group. Each rat in the third group was intraperitoneally administered 5 ~tg GLP-2 for 5 d before the procedure. A portal triad was created to induce ischemia with a vascular atraumatic clamp. After 40 min, the clamp was released to initiate hepatic reperfusion for 6 h. Blood samples and tissue specimens from the fiver were obtained. Alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels significantly increased in the saline- treated HIR group （P 〈 0.001）, whereas GLP-2 pretreatment significantly decreased their levels （P 〈 0.01）. Our data suggested that GLP-2 pretreatment may have a protective effect on liver I/R injury. However, dose-response studies are necessary to determine the most effective dose.

Endoscopic retrograde cholangiopancreatography during pregnancy without radiation

World Journal of Gastroenterology 2009年第29期15卷 3649-3652页

AIM： To present our experience with pregnant patients who underwent endoscopic retrograde cholangiopancreatography （ERCP） without using radiation, and to evaluate the acceptability of this alternative therapeutic pathway for ERCP during pregnancy. METHODS： Between 2000 and 2008, six pregnant women underwent seven ERCP procedures. ERCP was performed under mild sedoanalgesia induced with pethidine HCI and midazolam. The bile duct was cannulated with a guidewire through the papilla. A catheter was slid over the guidewire and bile aspiration and/or visualization of the bile oozing around the guidewire was used to confirm correct cannulation. Following sphincterotomy, the bile duct was cleared by balloon sweeping. When indicated, stents were placed. Confirmation of successful biliary cannulation and stone extraction was made by laboratory, radiological and clinical improvement. Neither fluoroscopy nor spot radiography was used during the procedure. RESULTS： The mean age of the patients was 28 years （range, 21-33 years）. The mean gestational age for the fetus was 23 wk （range, 14-34 wk）. Five patients underwent ERCP because of choledocholithiasis and/or choledocholithiasis-induced acute cholangitis. In one case, a stone was extracted after precut papillotomy with a needle-knife, since the stone was impacted. One patient had ERCP because of persistent biliary fistula after hepatic hydatid disease surgery. Following sphincterotomy, scoleces were removed from the common bile duct. Two weeks later, because of the absence of fistula closure, repeat ERCP was performed and a stent was placed. The fistula was closed after stent placement. Neither post-ERCP complications nor premature birth or abortion was seen. CONCLUSION： Non-radiation ERCP in experienced hands can be performed during pregnancy. Stent placement should be considered in cases for which complete common bile duct clearance is dubious because of a lack of visualization of the biliary tree.

Review of methods for predicting in situ volume change movement of expansive soil over time

引用

Journal of Rock Mechanics and Geotechnical Engineering 2015年第1期7卷 73-86页

作者： Hana H.adem Sai K.Vanapalli Department of Civil Engineering University of Ottawa

The soil movement information over time is required for the design of foundations placed in expansive soils. This information is also helpful for the assessment of pre-wetting and controlled wetting mitigation alternatives for expansive soils. Several researchers during the past fifteen years have proposed different methods for the prediction of the soil movements over time. The available methods can be categorized into(i) consolidation theory-based methods,(ii) water content-based methods, and(iii) suction-based methods. In this paper, a state-of-the-art of the prediction methods is succinctly summarized. The methods are critically reviewed in terms of their predictive capacity along with their strengths and limitations. The review highlights the need for prediction methods that are conceptually simple yet efficient for use in conventional engineering practice for different types of expansive soils.

AIM: Intrabiliary rupture (IBR) is a common and serious compli-cation of hepatic hydatid cyst. The incidence varies from 1% to 25%. The treatment of IBR is still controversial. We aimed to design an algorithm for the treatment of hepatic hydatidosis with IBR by reviewing our ***: Eight cases of IBR were analyzed *** were evaluated according to age, sex, clinical findings, cyst number and stage, abdominal ultrasonography and CT-scan, surgical methods, complica-tions, results and coincidental ***: Female/male ratio was 1/7. Mean age was 52.12±18.26 years (range 24-69 years). Right upper quadrant pain, flatulence, palpable hepatic mass were symptoms common in all patients. Cholestatic jaundice was found in four cases. In all patients, cyst evacuation and omento-plasty were performed, followed by either choledochod-uodenostomy, T-tube drainage, intracavitary suturing of the orifice, two cases in each. Whereas in two patients diagnosed post-operatively percutaneous drainage of biliary collection or ERCP and sphincteroplasty were added. Morbidity and hospital stay were higher in these ***: When the diagnosis of IBR can be done pre-or intra-operatively, morbidity decreases. If a biliary fistula is seen post-operatively, endoscopic procedures such as ERCP, sphincteroplasty or nasobiliary drainage can be applied.
