[Postoperative pulmonary complications following surgery for carcinoma of the esophagus].

Pulmonary complications frequently occur during the postoperative period following surgery for neoplasms of the oesophagus. The aetiology varies according to the time of their onset but the clinical signs and treatment are essentially the same. The problems encountered and related either to anaesthesia, to the surgical approach to the position of the patient. It is after the third day that complication develop related at one and the same to the past history, classical in such patients, (tobacco, chronic bronchitis, alcoholism) and the ectopic position of an abdominal viscus.

Calbindin D-28K immunoreactivity of human cone cells varies with retinal position.

Calbindin D-28K is a calcium-binding protein found in the cone but not rod photoreceptor cells in the retinas of a variety of species. Recent studies of the monkey retina indicated that calbindin D-28K may be expressed preferentially in non-foveal regions of the retina. In the current studies of human retinas, immunohistochemical experiments demonstrated that calbindin D-28K is reduced or absent in the fovea and parafovea, but prevalent in the perifovea and periphery. These findings were supported by the quantification of calbindin D-28K in 1-mm trephine punches obtained from different regions of the human retina. The specificity of the anti-calbindin D-28K antibodies used in these studies was confirmed by Western blot analysis using purified calbindin D-28K. The protein was purified from retinal tissue and its identity confirmed by partial amino-acid sequence analysis. The expression of calbindin D-28K did not correlate with the spectral properties of the cones, rather to their position in the retina. The study of spatially expressed genes, like the one encoding calbindin D-28K, may help explain the patterns of retinal degeneration seen in some human cone-rod dystrophies.
