Pernicious anaemia among Arabs in Kuwait.

Addisonian pernicious anaemia is believed to be very rare in Arabs. Three cases are reported. Two were Jordanians of Palestinian origin and one an Egyptian. All had the typical peripheral macrocytosis, a frankly megaloblastic bone marrow, and a Schilling test result in the range of pernicious anaemia. All three improved remarkably on vitamin B(12) therapy and have maintained a normal haemoglobin level. There was no evidence of gastric carcinoma in any of these cases.

Haemoglobin H disease in Arabs in Kuwait.

Three cases of haemoglobin H disease are described in Arabs, two of Syrian and one of Kuwaiti origin. Two were investigated on account of moderate anaemia, the third for splenomegaly not associated with anaemia.

Topical anesthesia with 50 mg of lidocaine spray facilitates upper gastrointestinal endoscopy.

To investigate the value of 50 mg of topical lidocaine spray in upper gastrointestinal endoscopy, a randomized double-blind placebo-controlled study was undertaken with 50 mg of lidocaine spray as the active treatment. All patients were sedated with diazepam after administration of the spray. Included in the study were 158 consecutive patients aged 18 years or older being treated at the endoscopy unit of Scunthorpe district general hospital. Tolerance to upper gastrointestinal endoscopy as assessed by endoscopists and patients was evaluated. Of the 158 patients, 85 received the placebo spray and 73 the lidocaine spray. Patient acceptability for upper gastrointestinal endoscopy was significantly greater in the lidocaine group than in the placebo group (p = 0.001), and tolerance to the procedure as assessed by the endoscopist was also significantly greater in the lidocaine group than in the placebo group (p = 0.008). We conclude that topical anesthesia with 50 mg of lidocaine spray facilitates upper gastrointestinal endoscopy for the endoscopist and increases patient tolerance for the procedure.

Influence of polymer structure on protein partitioning in two-phase aqueous systems.

Copolymers of acrylamide and styrene with two distinct structures were synthesized to study the effect of polymer structure on protein partitioning in two-phase aqueous systems. Micellar copolymerization was used to prepare a multiblock copolymer, while homogeneous copolymerization was used to prepare a random copolymer, both with the same composition and molecular weight. Phase behavior studies of the copolymers with poly(ethylene glycol) in water showed little difference in the phase boundaries. However, the partitioning of bovine serum albumin between the two aqueous phases was sensitive to the polymer structure. A molecular picture is proposed for the interactions between the protein and block copolymers. The effect of pH on the protein partition is analyzed in terms of the hydrophobic interactions, and the polymer and protein partitioning was correlated using a model based on the Flory-Huggins theory.

Bacterial infertility in camels (Camelus dromedarius): isolation of Campylobacter fetus.

This study constitutes the first reported isolation of C. fetus subsp. venerealis from cervical swabs in breeding camels. 9 of 30 camels which were barren for a long period were found to be positive for C. fetus. The methods of isolation are described. Additionally, cervical flora of 30 camels were examined. 9 different bacterial species were isolated of which Staphylococcus aureus was most frequently found. All samples were negative for Trichomonas sp. and Streptococcus zooepidemicus.
