The angiosperms are characterized by vessels in wood, and therefore, vessel elements were selected to study them in climber species. Xylem is the specialized tissue that transports water and nutrients from the plant–soil interface to stem and leaves and provides mechanical support and storage. Water is the primary solvent for plant nutrition and metabolism and is essential for photosynthesis, turgor and for transport of minerals, hormones and other molecules. Studies on vessels showed that the characters of vessels can throw some light on the phylogeny of species. The short vessel members with many perforation plates with a single large perforation are most specialized and those that were long with elongate obliquely placed perforation plates with many perforations separated by bars that together give a scalariform appearance are primitive. The degree of specialization of vessel elements can be measured in terms of vessel length, breadth and the number of bars on the end plate of vessels. Vessels show highly evolved and primitive vessel elements. Mostly elongated vessel elements are present in middle region of the stem. During this study the broadest vessels were found in the middle part of the stem of dicots (Clitoria, Daemia and Aristolochia) and root of the monocots (Gloriosa) and the narrowest vessel elements were found in different parts of the species investigated. The present work is supported with line drawings of prepared stained sections, provides a framework of the vessels. This study will be very useful to a wideseries of community, who work with plants.

Introduction: This prospective study was carried out to evaluate the factors that affect the graft take rate as well as hearing improvement after myringoplasty. Method: In this study 60 patients were divided into several groups based on 4 factors like size of perforation (small, medium and large), site of perforation (anterior central, posterior central and central malleolar), Condition of the middle ear (dry & wet) and surgical approach (post auricular and transcanal). Surgical outcome of myringoplasty was measured on the basis of graft take rate and post operative hearing improvement. Results: Size of the perforation affects the graft take rate and post operative hearing gain. Post operative closure of air-bone gap was 10.45 dB, 19.21 dB and 18.86 dB in small, medium and large perforation respectively. Hearing gain was greater after closure of large perforation than the smaller one. Graft take rate was 100%, 82% and 72.73% in small, medium and large perforation respectively. Graft take rate was greater in small perforation than other. Site of perforation also affects surgical outcome after myringoplasty. Graft take rate in anterior central, posterior central and central malleolar perforation was 66.67%, 82.25% and 83.79% respectively. Graft take rate was higher in central malleolar perforation than anterior central perforation. Post operative air-bone gap closure after myringoplasty was 15.31 dB, 12.38 dB and 20.89 dB in anterior central, posterior central and central malleolar perforation respectively. Post operative improvement of hearing was greater in central malleolar perforation. Condition of middle ear at the time of operation also affects the surgical outcome. Graft take rate was 89.36% in dry perforation and 53.85% in wet perforation. Graft take rate was greater in dry perforation. Closure of air-bone gap was 18.23 dB and 7.8 dB in dry and wet perforation respectively. Hearing improvement was greater in dry perforation. No significant difference was found in post-aural and transcanal approach. Conclusion: From this study we concluded that site and size of tympanic membrane perforation and condition of middle ear effects surgical outcome after myringoplasty. Key words: Myringoplasty; hearing improvement; graft take rate. DOI: http://dx.doi.org/10.3329/bjo.v17i2.8846 BJO 2011; 17(2): 82-87

Large Perforation

Traumatic perforation of the esophagus during esophagoscopy is an ever present danger that can have long lasting or lethal effects. All are agreed on the need for early diagnosis. The question is often asked whether treatment should be nonoperative or operative. The results of management in this series of 21 patients support the opinions of those who advocate early adequate drainage of the mediastinum by means of mediastinotomy or thoracotomy, with support by antibiotic therapy, nothing by mouth and careful observation, if a large perforation is present. In minor perforations conservative treatment alone may suffice but should be accompanied by alert clinical observation.

Background: The mortality of perforation peritonitis is highly dependent on early approach to the hospital, quick diagnosis and prompt surgical treatment as it correlates with the duration and degree of peritoneal contamination, the patient's age, the general health of the patient and the nature of the underlying aetiology. The present study was done to assess the role of various prognostic factors which have a bearing on the final outcome of the patients.Methods: This prospective observational cross-sectional study was conducted in the at a tertiary level hospital in Maharashtra, in which 47 patients who presented a surgical emergency of perforation peritonitis and underwent an exploratory laparotomy were included. We compared different variables between patients who survived and those who died. Results: High mortality was also found in patients who presented after 24 hours of developing symptoms. Ileal perforation was significantly more common among dead patients (50%) as compared to patients who survived (20%), p-value<0.05. There were significantly higher proportion of patients who had shock on day 1 who died (67%) as compared to those who survived (12%), p-value<0.05. Also, the group of patients who died, had significantly higher MPI (p-value<0.01), higher proportion of patients with multiple perforations (p-value<0.05), larger perforations (p-value<0.01) and contamination more than 1000 ml (p-value<0.05).  Conclusions: High mortality was observed in patients who presented late, had ileal perforations, multiple and large perforation and developed shock on day one.

Duodenal Perforations

Laparoscopic repair of perforated duodenal ulcers is safe and effective in centers with experience and increasingly performed by laparoscopic surgeons. However, the role of laparoscopy for the management of large duodenal perforations (>1 cm) is unclear. To date, no experience has been reported with emergency laparoscopic repair of large perforations for gastroduodenal ulcers. The commonest reason for conversion to open surgery is a perforation size of more than 1 cm. This paper reports a case of a large duodenal perforation due to a nasogastric tube in a 26-year-old male who had undergone a tracheostomy, following a cut-throat injury. This large perforation was successfully diagnosed and repaired laparoscopically. This is probably the first paper in the English literature to report duodenal perforation due to a nasogastric tube in an adult and also the first report of a successful laparoscopic repair of a large duodenal perforation.

SummaryA Helica short-stemmed femoral prosthesis that was identified as being loose one year after implantation was revised with a standard long stem cementless BFX femoral pros-thesis. A double pelvic osteotomy was also performed to improve the orientation of the stable acetabular cup. Despite complete resorption of the femoral neck, and a large perforation of the lateral femoral cortex, the revision stem did not subside or rotate. The prosthetic joint did not dislocate. At re-evaluation two years after revision surgery, the prosthetic components were stable. Signs of bone ingrowth into the stem and cup were evident on radiographs. The dog had a seven percent greater thigh muscle girth in the limb implanted with the hip prosthesis compared to the contralateral limb, and was very active with no lameness.
