چکیده
It is well established that a proportion of patients with tobacco amblyopia have pernicious anaemia or some other demonstrable defect of vitamin B12 metabolism (Leishman, 195I; Heaton, McCormick, and Freeman, I958; Freeman and Heaton, I96I; Foulds, Chisholm, Bronte-Stewart, and Wilson, I968). We have examined 65 cases of tobacco amblyopia diagnosed according to the criteria of Heaton and others (I958) for evidence of defective vitamin B12 metabolism, with particular reference to vitamin B12 absorption.

It is well established that a proportion of patients with tobacco amblyopia have pernicious anaemia or some other demonstrable defect of vitamin B12 metabolism (Leishman, 195I; Heaton, McCormick, and Freeman, I958; Freeman and Heaton, I96I; Foulds, Chisholm, Bronte-Stewart, and Wilson, I968).

متن کاملAbsorption of vitamin B12 in tobacco amblyopia.
In view of the evidence that some abnormality of the metabolism of vitamin B12 is present in tobacco amblyopia (Callender and Denborough, I957; Heaton, McCormick, and Freeman, I958; Chisholm, Bronte-Stewart, and Foulds, I967), it was thought possible that absorption of the vitamin might be reduced in patients with the disease. The patients studied were male pipe smokers with bilateral acquired ...

متن کاملRole of vegetarianism, smoking, and hydroxocobalamin in optic neuritis.
Only 20 patients with optic neuritis of unknown aetiology could be collected in Bombay over a period of two and a half years. Only six of them were smokers and only three (one a non-smoker) had bilateral centrocaecal scotomata similar to those found in tobacco amblyopia. In 11 untreated patients the serum vitamin B(12) and plasma thiocyanate levels were estimated and found to show no significan...
متن کاملThe role of the pancreas in vitamin B 12 absorption: studies of vitamin B 12 absorption in partially pancreatectomized rats.
The effect of partial pancreatectomy (80-90%) on vitamin B(12) absorption was studied in the rat. The absorption of 5 ng of (57)Co-labeled vitamin B(12) was significantly reduced from 70 +/-2.5% (mean +/-SE) in control and sham-operated rats to 32 +/-2.6% in partially pancreatectomized rats. Hog pancreatic extract (0.17 g/kg) improved vitamin B(12) absorption from 30.0 to 61.0% in partially pan...
