Osteosarcoma (OS), a rare malignant bone tumour arising from primitive bone forming mesenchyme, most often arises in the metaphyses of long bones of the extremities. Bone or osteoid formation within the tumour is characteristic of an osteosarcoma. Craniofacial osteosarcoma (CFOS), most often located in the mandible or maxilla, accounts for only 5-13% of all(More)
A small epidemic of Leishmania tropica infection was detected in Rajasthan, India. Most cases were in the 21-25 years age group and were possibly related to outdoor activity. Nearly one third of the patients had more than five lesions, the maximum number of lesions being confined to the face, neck and extremities. As determined by ELISA, 90% cases had(More)
Data on 41 kala-azar patients were collected and the series of serological tests employed to diagnose the disease were compared depending upon their sensitivity and specificity indices. The indirect fluorescent antibody test (IFAT) was found to be 100% sensitive and specific. The direct agglutination test (DAT) involving detection of agglutinating(More)
Twenty-one monoclonal antibodies were produced against promastigote antigens of Leishmania donovani. Five monoclonal antibodies (Hyb.17, 6, 5, 4 and 2) identifying molecules associated with various L. donovani antigenic determinants ranging from 42-116 kDa were selected as 'capture antibodies' and compared with specific anti-leishmania antisera for(More)
The hypothalamo-limbic system has been implicated in recognizing the affective significance of pain and elicitation of related emotional responses. Several evidences from different studies support a role of these areas in endogenous analgesic mechanisms for pain modulation as elucidated by different pain tests in more than one animal model. In the above(More)
PURPOSE The aim of this study was to clinically evaluate the application of pedicled buccal fat pad (BFP) in the surgical management of stage III and IV oral submucous fibrosis (OSMF). MATERIALS AND METHODS Twenty-eight cases of clinically and histologically diagnosed cases of OSMF were divided into 2 groups: group I (n = 15) and group II (n = 13),(More)
