ABSTRACT
Introduction: Adenomatoid odontogenic tumor (AOT) is a rare epithelial odontogenic tumor of jaws. It is a benign, painless, non-invasive, slow-growing lesion, with a frequency of 2.2-7.1%. Upon clinical examination it can be misdiagnosed as an odon- togenic cyst. AOT affects young individuals with a female predominance, occurs mainly in the second decade, more common in anterior maxilla and usually surrounds the crown of unerupted tooth mostly impacted canine. AOT has three clinical subtypes named as follicular, extrafollicular, and peripheral. Clinical presentation: This case report represents a 20 years old female patient with the chief complaint of swelling on the right upper anterior region for 8 months. Management and prognosis: After surgical excision and histopathological evaluation it is diagnosed as a rare case of extrafol- licular variant of intraosseous AOT.
ABSTRACT
A field experiment was carried out at Agriculture Farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, India during kharif season of 2015 to compare rice cultivation in conventional transplanting (CT) and system of rice intensification (SRI) in terms of energy use, energy input output relationship and green house gas emission. Results showed that regardless of cultivars, conventional transplanting consumed 62.39% higher energy over SRI. Maximum energy input was associated with non renewable and indirect sources. Higher dose of nitrogenous fertilizer had contributed to 32.35% and 26.26% to the total input energy in CT and SRI respectively. Energy use efficiency (13.22), energy productivity (6.94 kg MJ-1), energy profitability (12.22) and energy intensity (4.60 MJ Rs-1) of hybrid rice varieties were noted higher in SRI. Maximum green house gas emission from rice field was also attributed to fertilizer nitrogen followed by diesel in both the system. Total green house gas emission in CT was estimated to 834.85 (kg CO2ha-1) i.e. 1.8 times of SRI. Engirdling different energy indices, total input energy and green house gas emission, the system of rice intensification was emerged as the most energy efficient and sustainable rice production system in resource stricken areas (Red Lateritic Zone).
ABSTRACT
Axillary bud explants were induced to form shoots on Murashige and Skoog's (MS)' basal medium. Best yield (9 shoots per explant) was obtained when the medium was supplemented with adenine sulphate (40 mg/L) and 6-benzylaminopurine (2.25 mg/L). The shoots were rooted on half strength MS basal medium supplemented with indole butyric acid (0.5 mg/L) and having thiamin-HCl (800 mg/L). Regenerated plantlets were successfully acclimatized. This is the first report of micropropagation in the genus Mussaenda without callus intervention.

BACKGROUND: Topical glyceryl trinitrate (GTN) may produce healing of anal fissure by decreasing the high resting anal sphincter pressure in these patients. The present study assessed the efficacy of GTN in chronic anal fissure in a double-blind placebo-controlled trial. METHOD: Patients with chronic anal fissure (for more than 8 weeks) underwent measurement of maximum anal resting pressure (MARP) before and 12 minutes after application of either 0.2% GTN or placebo ointment in a randomized manner. They then received twice-daily local application of their respective ointment for 6 weeks. Symptoms and healing of fissure were assessed; patients were evaluated at 3 months for evidence of relapse. RESULTS: 19 adult patients (12 men) were studied; 10 received GTN and 9 placebo. Mean (SD) MARP decreased from 131.0 (32.3) cm H2O to 93.5 (28.4) cm H2O (p<0.05) with GTN and from 150.5 (36.9) cm H2O to 142.8 (35.0) cm H2O (p=ns) with placebo. Fissure healed in 7 of 10 patients treated with GTN and 2 of 9 patients treated with placebo (p<0.05). There was no relapse of fissure in either group. CONCLUSION: Local application of GTN was effective in healing chronic anal fissure.
