41. The effect of mepartricin on the reabsorption of estrogens was evaluated in studies in vitro and in vivo. 42. It is thought to function in salt reabsorption in the kidney and potassium recycling in the inner ear. 43. This complex process of reabsorption is usually one of the first renal functions to be affected by disease. 44. Therefore, nutrient reabsorption during senescence presents an opportunity for a plant s future net primary production use. 45. Hyponatremia can also promote lithium retention by increasing reabsorption in the distal nephron, thus increasing lithium levels. 46. SGLT-2 is responsible for 90 % of the reabsorption but SGLT-1 for 10 %. 47. PTH acts to decrease phosphate reabsorption from the renal filtrate and therefore promote its excretion into the urine. 48. Prozac and some other antidepressants slow the reabsorption of the neurotransmitter serotonin after it is released from nerve cells. 49. The drugs block the reabsorption of serotonin, thus boosting available levels of the mood-altering brain chemical. 50. With limited urobilinogen available for reabsorption and excretion, the amount of urobilin found in the urine is low.
