The neural mechanism of rectal motility response induced by the epicardial application of lactic acid.
The epicardial application of lactic acid induced a biphasic rectal motility response in lightly anaesthetised, open-chested and artificially ventilated cats. This rectal biphasic response is reflexogenic in nature as epicardial lignocaine abolished such response. This rectal biphasic response is abolished by cardiac sympathectomy and reprecipitated by left inferior cardiac afferent nerve stimulation. Such response is also abolished by sacral ventral rhizotomy and reproduced by stimulation of the peripheral cut end of split sacral ventral roots. This indicates that the afferent and efferent pathways for such reflex are lying in the cardiac sympathetic and sacral pelvic nerves, respectively. The higher centers involved for such reflex are lying above the mid-collicular level of the brain as decerebration at the mid-collicular level completely abolished such type of rectal response. Furthermore, the relaxation phase and contraction phase of such rectal response are mediated through nitric oxide release and cholinergic neurones, respectively, as NG-nitro-L-arginine and atropine abolished relaxation and contraction phase of the rectal response, respectively.

A computational study of convoluted back projection algorithm.
Image reconstruction by computerized tomography is a complex mathematical process. This paper describes the practical implementation of a tomographic reconstruction algorithm on different types of computers (micro to mainframe) and in different programming languages (BASIC to OCCAM) and performance studies were made.

Fine needle aspiration cytology of the spleen in visceral leishmaniasis.
We describe the fine needle aspiration cytologic study of 210 splenic aspirates from patients clinically diagnosed as having visceral leishmaniasis. Of these, 147 aspirates were found to be positive for Leishmania donovani bodies. We highlighted the cytomorphology of these positive smears. A majority of the cases showed an increase in the number and size of reticuloendothelial cells, with altered shapes, variations in the cytoplasm and decreased white pulp elements. In some of these cases (10%), immature erythroid cells were also found.
