Evaluation of ophthalmic materials. | Ophthalmic materials from 11,677 spectacle-prescription orders were evaluated during an 18-mo period in a university optometry clinic. Five percent of the orders received were not acceptable based on criteria stemming from the ANSI-Z80. 1-1972 standards. Almost two-thirds of these rejections were lens related.

Gross morphology of the alimentary canal in 10 teleostean species. | The gross morphology of 10 teleostean alimentary canals was compared. Each short, tubular esophagus was connected either to a stomach or, in the agastric species, to a proximal intestinal swelling. 3 stomach types were differentiated according to their shapes, which appeared to be correlated somewhat with diet.

Neural neurotization. | Controlled experimentation using dogs has demonstrated that free nerve-end insertion into a denervated muscle that has lost its motor nerve at the point of entry into that muscle can sprout axons at its implanted end to unite with neuromuscular endplates, either preexisting or new, and result in a functioning muscle.

Lack of effect of morphine and buprenorphine on hypoxic pulmonary vasoconstriction in the isolated perfused cat lung and the perfused lobe of the dog lung. | In an isolated perfused cat lung preparation and a perfused lobe of dog lung preparation a pressor response of the pulmonary circulation was elicited to alveolar hypoxia (5% oxygen). The magnitude of this reponse was not affected by either of the opioid drugs, morphine or buprenorphine. | 747,691 | [

[Which thyroid nodules need to be operated? (author's transl)]. | Up to 20% of isolated cold thyroid nodules are malignant neoplasms.

In cases of hot nodules the risk of cancer is regarded as almost nil, but such nodules c... | 749,485 | [
