PDF-EFFECT OF PYRIDOXINE ON THE TRANSPORT OF IRON ACROSS MICRO FILTER SUPPORTED BILAYER LIPID

Model membranes can be readily prepared by directly immersing microfilter nylon into lipid solution The potential and conductance of model membrane prepared was measured using potentiometer and conductivity meter respectively In this paper the effect of pyridoxine drug on iron transport across microfilter supported bilayer lipid membrane prepared from lipid called Phosphatidylcholine was studied and the data of its conductance and potential were analyzed with the presence and absence of this drug.

Sumeet Prakash Mirgh, Jehangir Soli Sorabjee. Isoniazid (INH) is a crucial drug in the prevention and treatment of tuberculosis. INH is commonly known to cause derangements in liver function tests and peripheral neuropathy due to pyridoxine deficiency in slow acetylators. However, in toxic doses it is known to cause severe neurologic manifestations and acute metabolic acidosis. INH toxicity is characterized by the clinical triad of repetitive seizures unresponsive to the usual anticonvulsants, metabolic acidosis with a high anion gap and coma. Hence, the diagnosis of INH overdose should be considered in any patient who presents to Emergency medical services (EMS) with the triad. Though accidental overdose of anti-tuberculosis drugs have been reported in children and adults, acute toxicity is rare. When recognized, intravenous pyridoxine and correction of acidosis with sodium bicarbonate and supportive treatment is effective. The condition is easily treated with intravenous pyridoxine but if not treated in time could prove fatal. Unlike other poisonings, serum INH levels do not co-relate with either symptomatology or liver injury..
