Evaluation of jute leaf as substitute of fish meal in the diet of mrigal (Cirrhinus cirrhosus) fingerlings

The study was conducted to identify jute leaf powder as an alternate to fish meal in diets of juvenile mrigal (Cirrhinus cirrhosus) for 60 days. Tossa jute (Corchorus olitorius) leaf was selected to utilize this unexplored nutritious resource rather leaving under water for potential pollution. Three isonitrogenous test diets were prepared and applied as treatments (T) in triplicates (R). In control (T0) dietary inclusion rate of fish meal was 30%, of which 10% was substituted with jute leaf powder in T10 and in T20 replacement was 20%. Mrigal fingerlings (9.38±0.13 cm and 7.94 ±0.26 g) were stocked in nine plastic half drums (0.26 m2 each) at 10 fish per drum and fed test diets. Although, growth parameters among the treatments were statistically similar, the highest mean length gain, weight gain, SGR and production were 1.51 (±0.18) cm, 2.96 (±0.13) g, 0.53 (±0.03) %/day and 4084.00 (±50.67) kg ha-1, respectively in T10. However, significantly higher (P<0.05) survival was found in T10 (93.33%) and T20 (90.00%) compared to T0 (83.33%). Juveniles in T10 and T20 showed better tolerance to low pH stress than T0. Water quality parameters were within acceptable range in all the treatments. Moreover, carcass composition of fish was statistically similar among the treatments. Importantly, feed formulation cost was reduced by 3.7% and 20.4% in T10 and T20, respectively compared to T0. Therefore, the results signify that jute leaf powder could be a promising substitute of fishmeal in mrigal diet without hampering growth along with improved survival and low feed cost. Int. J. Agril.

Aged leaves effect on essential components in green and oolong tea

Tea leaf encompasses essential components like caffeine, polyphenol, lipid etc. The study was conducted to find out the essential constituents in green and oolong tea from aged tea leaves during the year of 2012. Tea leaves with different plucked aged were collected from Lackatoorah Tea Estate at sylhet district in Bangladesh. Collected leaves were processesed to make desirable samples for biochemical analysis in the laboratory of Department of Food Enginnering and Tea Technology, SUST. Results revealed that the essential constituents like moisture, caffeine, polyphenol, lipid, protein, ash, ascorbic acid, acidity and pH value in green tea made from different aged leaves were found slightly higher than oolong tea, ranged from 6.38±1.06 to 3.49±0.59%; 4.91±0.82 to 1.49±0.24%; 30.88±5.15 to 18.23±3.04%; 7.50±1.25 to 9.58±1.59%; 13.15±2.19 to 17.33±2.88%; 3.87±1.65 to 7.86±1.31%; 48.4±8.05 to 21.3±3.55(mg); 2.13±0.68 to 1.18±0.19% and 5.52±0.11 to 5.97±0.18%, respectively. Similarly, the moisture, caffeine, polyphenol, lipid, protein, ash, ascorbic acid, acidity and pH value from different aged leaves were found in oolong tea from 6.19±1.04 to 2.98±0.49%; 4.68±0.78 to 1.11±0.19%; 20.89±3.48 to 8.23±1.37%; 6.40±1.07 to 9.13±1.52%; 13.03±2.17 to 17.19±2.86%; 3.44±0.58 to 7.57±1.27% 6.44±1.08 to 0.98±0.17 (mg); 2.02±0.34to 1.02±0.17% and 5.53±0.11 to 5.97±0.20%, respectively. Therefore, young tea leaves (i.e. 5 to 8 days tea leaves) should be plucked for considering useful constituents in processed green tea and oolong tea.

An institutional review of transarterial embolization in haemorrhagic urological emergencies

OBJECTIVE: To review the effectiveness of therapeutic transarterial embolization in controlling phagic urological emergencies irrespective of the cause of emergencies. METHODS: Thirty-seven vascular angiographies were performed in 32 patients (19 males and 13 females, age range 19-70 years) who were referred with haemorrhagic urological emergencies to Aga Khan University Hospital\u27s angiography suite from July 2005 to June 2010. Embolization was performed with coils, polyvinyl alcohol particles, N-Butyl cyanoacrylate glue and gel foam according to the clinical indication. Data on clinical indication, technique, site and type of bleeding lesions were obtained from a retrospective review of medical records. Success rate, clinical outcome and complications of the procedure were analysed. RESULTS: Indications of procedure included iatrogenic injury (16), Renal mass on clinical examination and imaging (4), haematuria with pseudoaneurysm on examination (3), haematuria with no known cause (3), post traumatic renovascular injury (2) Renal arteriovenous fistulas (2), Carcinoma of prostate (1) and pelvic arteriovenous (AV) fistula (1). Twenty four patients underwent successful endovascular control of bleeding. Eight examinations were negative for active extravasation, two of whom showed haemorrhage in second session and were embolized. Two sessions were needed in two patients at different time intervals. Complication as dislodgement of coil in distal profunda femoris artery was seen in one patient with no significant obstruction to flow. CONCLUSION: Transarterial renal angioembolisation is a safe and effective therapeutic tool for managing haematuria or haemorrhage in urological emergencies. Wherever and whenever indicated it should be the first preferred treatment modality

Treatment of intracranial aneurysms using detachable coils; initial results at a university hospital in Pakistan

OBJECTIVE: To evaluate the technical success, safety and outcome of endovascular coiling procedure in intracranial aneurysms. METHODS: From April 2003 to April 2009, 43 patients (23 males and 20 females), age range 11 to 70 years, mean age 46.67 +/- 11.57 years were treated for intracranial aneurysms by detachable coil deployment at Radiology Department of Aga Khan University Hospital. Aneurysm rupture with subarachnoid haemorrhage was the cause of presentation in 39 patients while 4 patients were diagnosed with un-ruptured aneurysms. At time of presentation, grading of subarachnoid haemorrhage was done according to Hunt and Hess grading system. Eleven patients presented with Grade I haemorrhage, other 11 presented with grade II haemorrhage, 8 patients had grade III haemorrhage and 9 patients had grade IV haemorrhage. Preliminary diagnostic workup was performed by cross sectional imaging, CT angiography or digital substraction angiography. Coiling procedures were performed under general anaesthesia through femoral artery approach. Detachable platinum coils were densely packed in all aneurysms by endovascular technique. Patient files and radiology reports were retrospectively reviewed. Technical success and safety of the procedure were analyzed. Modified Rankin Score was used to determine clinical outcome. Score 0-2 represented good outcome, score 3-5: dependency (Can not attend own bodily needs and carry out daily activities without assistance) and score 6: death. RESULTS: Aneurysm size ranged from 3mm - 22mm (mean size 8 mm +/- 4). 74.4% aneurysms had narrow necks while 25.6% aneurysms were wide necked. Most common aneurysm site was anterior communicating artery. Technical success rate for endovascular intracranial aneurysm coiling was 95.3% (n = 41). Major complication rate was 11.6 % (n = 5). Mortality rate was 2.3% (n = 1). 78% patients showed good clinical outcome after coiling including 4 patients with un ruptured aneurysms (n = 32). CONCLUSION: Results of endovascular aneurysm coiling at our center showed high technical success rate (95.3%) and good short term clinical outcome in 78% patients

Airflow in Urban Environment: an Approach to Improve Egyptian Buildings Regulations

Rapid urbanization among many factors contribute to elevate air temperature inside city’s urban fabric that causes urban human discomfort. Natural ventilation in urban canyons is one of the measures that can limit that effect and minimize the air temperature of urban areas. Benefits range from pedestrian comfort in the urban environment, to efficiency of natural ventilation systems in urban streets. Studies have covered different urban forms and their impact on pedestrian comfort, others have investigated the role of built-up density on pollutants dispersion, some have studied the role of urban configurations on natural ventilation in buildings, while some studied different physical characteristics which also affect the urban heat island. What is yet to be defined is the effect of those physical characteristics on shaping the building regulations, especially in Egypt, and their efficiency regarding natural ventilation systems in urban canyons to eliminate the raised temperature. Spreading green architecture in Egypt requires reshaping current legislation and codes, starting by revising the existing local building laws and regulations. The aim of this work is to assess and analyse the main building code in Egypt by studying and analysing theories on natural ventilation and its physical characteristics

Endovascular approach as primary treatment for traumatic carotid cavernous fistula: Local experience from Pakistan

Objective: To evaluate the technical success, complications and outcome of endovascular management of post traumatic carotid cavernous fistula (CCF) in patients presenting at a tertiary care hospital in Karahci.Methods: Descriptive case series of 26 patients of post traumatic CCF treated by endovascular techniques was carried out at Radiology and Neurosurgery departments of Aga Khan University hospital between January 2010 to March 2010. Medical records and radiology reports were retrospectively reviewed from November 2000 to December 2009. The diagnosis was primarily clinical and was confirmed in all cases by CT or MRI. Endovascular procedures were performed under general anaesthesia through femoral artery or femoral vein approach. Detachable balloons pushable coils and/or glue was used for fistula closure. Follow up was done via medical records and on phone. Technical success and safety of the procedure were analyzed and outcome in terms of symptomatic improvement was recorded wherever available.Results: Out of a total of 26 patients; 20 were male and 6 were female, with age range of 14 to 62 years, mean age 31.4 +/- 12.6 years. Technical success rate of endovascular embolization was 92.3% (24 out of 26 patients). Procedure could not be performed in 2 patients. In 20 out of 24 patients (83.3%) single session of embolization was performed while 4 patients required 2 sessions due to recurrence. In one of these patients the detachable balloon deflated after 2 hours of deployment and another session of embolization was immediately carried out by deploying a larger sized balloon. Complication rate was 15.3% (n = 4) one patient had infarction which recovered completely in 6 months. There was no procedure related mortality. Five patients were lost to follow up. In rest of the 19 patients follow up ranged from 1 to 14 months (Mean 11.0 +/- 11.8 months) 8 out of 19 (42.1%) patients showed complete resolution of symptoms and 9 (47.3%) reported improvement.Conclusion: Endovascular approach is a safe and useful option for treatment of traumatic carotid cavernous fistula

Transjugular intrahepatic portosystemic shunt (TIPS); review of initial experience at Aga Khan University Hospital

OBJECTIVE: To retrospectively assess the therapeutic effectiveness and safety of transjugular intrahepafic portosystemic shunt (TIPS) in patients with portal hypertension related complications. METHODS: Over a period of 7.5 years 19 patients (10 males and 9 females, age range 25-69 years) were referred for TIPS at our radiology department. Thirteen patients suffered from liver cirrhosis while 6 had Budd Chiari syndrome. All patients were evaluated with colour doppler ultrasonography and cross sectional imaging. Shunt procedures were performed under sedation or general anaesthesia through internal jugular approach. Metallic self expandable uncovered stents were placed in 15 patients and covered stent in 1 patient. Follow up of patency was evaluated with ultrasound in majority and by venography in some patients. Safety of the procedure and clinical outcome were analyzed. RESULTS: Indications of procedure included variceal bleeding (n=8), ascites (n=4), ascites and bleeding (n=1) and Budd-Chiari syndrome (n=6). Technical success rate was 84.21%. Complication rate was 10.53%. Three days mortality was 15.79%. Mean primary shunt patency was 306.62 +/- 533 days. During follow-up stent occlusion occurred in 5 patients (31.25%). Four of these patients underwent successful reintervention. Recurrence of symptoms occurred in 68.75% patients. CONCLUSION: TIPS is useful for management of complications of portal hypertension that are refractory to pharmacological and endoscopic treatment, however shunt stenosis or occlusion may cause recurrence of symptoms. Repeated interventions are often required to maintain shunt patency
