Intermittent Transient Motor Aphasia Associated with Acute Lithium Toxicity: A Case Report and Brief Review.

Background: Lithium is known to cause certain neurological deficits. However, reports of aphasia secondary to lithium toxicity are scant. We report the case of a 70 year old African American woman with a history of schizoaffective disorder and mild dementia who developed transient intermittent aphasia secondary to lithium toxicity.

CFTR mediated chloride secretion in the avian renal proximal tubule.

In primary cell cultures of the avian (Gallus gallus) renal proximal tubule parathyroid hormone and cAMP activation generate a Cl(-)-dependent short circuit current (I(SC)) response, consistent with net transepithelial Cl(-) secretion. In this study we investigated the expression and physiological function of the Na-K-2Cl (NKCC) transporter and CFTR chloride channel, both associated with Cl(-) secretion in a variety of tissues, in these proximal tubule cells. Using both RT-PCR and immunoblotting approaches, we showed that NKCC and CFTR are expressed, both in proximal tubule primary cultures and in a proximal tubule fraction of non-cultured (native tissue) fragments.
