Nutritional muscular dystrophy (NMD) in the chick results from a simultaneous deficiency of vitamin E and cystine. Muscle and liver of dystrophic and nondystrophic chicks were assayed for nonprotein sulfhydryl (NP-SH), reduced glutathione (GSH) and glutathione reductase. Red blood cells were assayed for NP-SH and GSH content. Glutathione peroxidase was determined in muscle, plasma and liver. Dystrophic muscle GSH was increased and at times was approximately double that of normal muscle, while liver GSH was lower in dystrophic than in normal chicks. During recovery from NMD, brought about by addition of either vitamin E or cystine to the dystrophogenic diet, muscle GSH declined and liver GSH increased to normal levels. Glutathione peroxidase was equivalent in both dystrophic and nondystrophic plasma and liver, but was significantly increased in dystrophic muscle. The mode of action of dietary cystine in preventing NMD in chicks remains unknown; it is not mediated through the role of amino acid as a component of the GSH needed for the action of glutathione peroxidase.

A public garden is an organization, open to the public, that curates a collection of plants and uses that collection to further its mission. The mission of many public gardens includes the cultivation and display of a wide range of plants-its collection-to address some purpose such as education, conservation, or aesthetic display (Rakow, 2011). Often referred to as living museums, public gardens also curate exhibits and education programs in support of its mission. Cornell Botanic Gardens' mission is to inspire people-through cultivation, conservation, and education-to understand, appreciate, and nurture plants and the cultures they sustain. Advancing this mission works toward the Gardens' vision: a world in which the interdependence of biological and cultural diversity is respected, sustained, and celebrated. This vision and mission was a key reason staff at the Gardens
