Item Involuntary jerking of lower half of the body (spinal myoclonus).(2005-02-26) Ray, B K; Guha, G; Misra, A K; Das, S KA 55 years old, hypertensive, diabetic lady presented with sudden onset jerky movement of lower trunk and legs. It was present both in awake and sleep and got aggravated by mental stress as well as sensory stimulation. Examination revealed rhythmic jerks affecting muscles of lower abdomen and legs. The lower limbs had normal muscle bulk and power, increased tone, exaggerated deep tendon reflexes, bilateral flexor plantar response with normal sensory autonomic and cerebellar function. Investigations including CSF study, MRI of dorsal spine and NCV were normal. A combination therapy with tizanidine, baclofen and clonazepam induced gradual improvement within 6 weeks.Item Levels of some nucleic acid hydrolases during growth inhibition and subsequent regression of mouse fibrosarcoma by treatment with rotenone.(1975-12-01) Sinha, S N; Ray, B K; Goswami, B B; Bhattacharrya, P; Dube, D KItem Regeneration of encapsulated protocorms of Phaius tankervilliae stored at low temperature.(1996-08-01) Malemnganba, H; Ray, B K; Bhattacharyya, S; Deka, P CEmbryos (80 days old) developed after selfing P. tankervilliae were cultured on Nitsch medium for protocorm development. Protocorms (70 days old) thus developed were encapsulated with alginate matrix. Ninety six per cent of freshly prepared encapsulated protocorms differentiated into shoots and roots when cultured on Nitsch medium. Storage of encapsulated protocorms in sealed petri plates or by embedding in liquid paraffin at 4 degrees C showed no reduction in their regeneration frequency up to 120 days when cultured on Nitsch medium. However, 90% of encapsulated protocorms stored at room temperature in empty petri plates differentiated within 35-40 days. Regeneration frequency of encapsulated protocorms was drastically reduced when stored in liquid paraffin at room temperature.Item Selective serotonin reuptake inhibitors-- few pitfalls.(2003-06-23) Ray, B K; Gunha, G; Sarkar, N; Mishra, A; Senapati, A; Das, S K
