An improved protocol for generation of viable cormlets from tissue culture derived shoots of saffron has been developed. Multiple shoots were generated from apical buds, small corms and in vitro developed single shoots. Bunches of two to three shoots when cultured on half strength Murashige and Skoog (MS) medium containing 3 mg dm -3 benzyladenine (BA) and 80 g dm -3 sucrose developed 1.89 cormlets per shoot bunch with an average fresh mass of 1.18 g. It took nine months from culture of apical buds to the harvest of cormlets but under field conditions 22 months. Sucrose appeared to be essential for cormlet induction as no cormlets were developed in the medium devoid of sucrose and only 0.29 per shoot in medium containing mannitol. In vitro derived cormlets sprouted from apical and axillary buds on MS medium containing 12 mg dm -3 BA, 3 mg dm -3 indolebutyric acid and 30 g dm -3 sucrose. Daughter cormlet formation from in vitro derived cormlets was also observed.
Human brucellosis is a multisystem disease that commonly presents as a febrile illness along with variable spectrum of clinical manifestations. Neurological complications include encephalitis, meningoencephalitis, radiculitis, myelitis, peripheral and cranial neuropathies, subarachnoid hemorrhage, and psychiatric manifestations. We report a case diagnosed as neurobrucellosis who presented with fever and bilateral upper motor neuron symptoms and signs along with bilateral sensorineural deafness. Diagnosis was confirmed by Rose Bengal Test (RBT) and standard tube agglutination test (SAT).
AIMTo investigated clinical, endoscopic and histopathological parameters of the patients presenting with ileocecal ulcers on colonoscopy.METHODSConsecutive symptomatic patients undergoing colonoscopy, and diagnosed to have ulcerations in the ileocecal (I/C) region, were enrolled. Biopsy was obtained and their clinical presentation and outcome were recorded.RESULTSOut of 1632 colonoscopies, 104 patients had ulcerations in the I/C region and were included in the study. Their median age was 44.5 years and 59% were males. The predominant presentation was lower GI bleed (55, 53%), pain abdomen ± diarrhea (36, 35%), fever (32, 31%), and diarrhea alone (9, 9%). On colonoscopy, terminal ileum was entered in 96 (92%) cases. The distribution of ulcers was as follows: Ileum alone 40% (38/96), cecum alone 33% (32/96), and both ileum plus cecum 27% (26/96). The ulcers were multiple in 98% and in 34% there were additional ulcers elsewhere in colon. Based on clinical presentation and investigations, the etiology of ulcers was classified into infective causes (43%) and non-infective causes (57%). Fourteen patients (13%) were diagnosed to have Crohn’s disease (CD).CONCLUSIONNon-specific ileocecal ulcers are most common ulcers seen in ileo-cecal region. And if all infections are clubbed together then infection is the most common (> 40%) cause of ulcerations of the I/C region. Cecal involvement and fever are important clues to infective cause. On the contrary CD account for only 13% cases as a cause of ileo-cecalulcers. So all symptomatic patients with I/C ulcers on colonoscopy are not Crohn’s.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
