Input: Consider Input: Abstract: To determine the effects of age on the myocardium, the functional and structural characteristics of the heart were studied in rats at 3, 10 to 12 and 19 to 21 months of age. Systemic arterial pressure, left ventricular pressure and its first derivative (dP/dt) and heart rate were comparable in the three animal groups. In the interval between 3 and 10 to 12 months, mean myocyte cell volume per nucleus increased 53 and 26% in the left and the right ventricle, respectively. The total number of myocyte nuclei remained constant in either ventricle. In the following period, between 10 to 12 and 19 to 21 months, a 39% further cellular hypertrophy on the left side of the heart was found in association with an 18% loss of cells in the ventricle. Cell loss was accompanied by discrete areas of interstitial and replacement fibrosis in the subendocardium. In contrast, no myocardial damage was observed in the right ventricle, and the measured 35% additional enlargement of myocytes occurred without a change in cell number. Thus, the aging left ventricle is composed of a smaller number of hypertrophied cells. Cellular hypertrophy may explain the unaltered cardiac function of the aged myocardium.

Input: Consider Input: Abstract: A mandatory seatbelt use law, the first such law in the nation, became fully in force in New York State as of 1 January, 1985. We studied seatbelt use among drivers and front seat passengers involved in motor vehicle accidents for a 3-month period pre-legislation (Phase 1), and a 5-month period post-legislation (Phase 2), to determine if this type of compulsory law, providing civil fines of $50 for violators, changes seatbelt use behavior. The reported use rate among drivers rose from 21% pre-legislation to 47% post-legislation (p less than 0.01). The use rate among front seat passengers rose from 21% to 40% (not significantly different due to the small number of occupants recorded in this position). A highway survey (Phase 3) noted the use rate in New York City and surrounding counties to be 63%, a marked increase from the published pre-legislation value of 16%. We conclude that mandatory seatbelt use legislation is effective in significantly increasing seatbelt use and urge physicians to seek similar legislation in every state.

Input: Consider Input: Abstract: We examined the occurrence of crystals and casts in the urine of healthy subjects after administration of triamterene and the site of crystal formation in experimental animals. Twenty out of twenty healthy subjects had abundant triamterene crystals and casts in acid urine after receiving a single 100 mg dose. Casts were present in the urine from 2-11 hours after administration of the diuretic. Cast formation occurred in acidic urine and was prevented by alkalinization of the urine with potassium citrate. Animal studies showed that crystallization and cast formation occurred in the medullary and papillary collecting ducts of the rat kidney. These findings provide a possible explanation for the reported nephrotoxicity of triamterene, particularly when given to patients who are receiving non-steroidal anti-inflammatory agents.
