Dietary protein intake and nutritional status in patients with renal transplant.

Background: Uremic patients on regular dialysis treatment (RDT) obtain and maintain with difficulty an adequate nutritional status. Successful kidney transplantation allows remarkable rehabilitation of patients with end-stage renal disease previously on RDT. However, information concerning the role of dietary protein restriction in the treatment of patients with chronic transplant rejection is scarce.

Posterior chamber intraocular lens use in children.

Purpose: The authors report on the efficacy of intraocular lens implantation during pediatric cataract surgery and the results of a consecutive series of intraocular lens implantation in children.

Methods: Twenty-one children underwent implantation of intraocular lenses in 23 eyes. Twenty-one surgeries were primary implantation immediately following anterior lensectomy.

Prostaglandins E1, E2, and D2 induce dark-adaptive retinomotor movements in teleost retinal cones and RPE.

In teleosts, retinomotor movements of photoreceptors and retinal pigment epithelium are regulated both by light and by an endogenous circadian rhythm. Light induces cones to contract, rods to elongate and RPE cells to disperse their pigment granules into their long apical projections; darkness induces opposite movements. When fish are maintained in prolonged constant darkness, appropriate movements nonetheless occur at subjective dusk and dawn.

Positive inotropic effect of K-canrenoate: an investigation in anaesthetized dogs, untreated or treated with digitalis.

Potassium canrenoate (KCR) is widely used in cardiac patients as an aldosterone antagonist, antiarrhythmic and diuretic drug. According to experimental and clinical studies it can also elicit an inotropic action. It is not clear, however, whether this inotropic activity occurs in the absence of any treatment or after the myocardial contractility has already been improved with digitalis.
