Effect of lead on Na+, K(+)-ATPase activity in Penaeus indicus postlarvae.

In vivo effect of lead on Na, K(+)-ATPase was studied in plasma membrane/mitochondrial fraction of P. indicus post-larvae (PL), exposed to 30 days to a sublethal concentration (1.44 ppm) of lead.

Prospective study of cortical sinovenous thrombosis value of CT scan and imaging.

Forty two consecutive cases of cortical sino venous thrombosis (CSVT) diagnosed by computerised tomographic scan (CT scan) and or magnetic resonance imaging (MRI) constituted the study material. Clinical features are similar despite of varied aetiology. Stroke like presentation was seen in 20 (48 percent) patients, features of raised intracranial pressure were seen in 14 (33 percent) patients and the remaining presented with diffuse encephalopathic features.
