Abstract
A prospective investigation was undertaken to assess the incidence of thrombosis after central venous cannulation. There were 63 patients. The incidence of thrombus formation in the last 20 of our patients was 90%. In 13% of the 63 patients there were serious sequelae to thrombosis--pulmonary embolism, major vein occlusion and septicaemia. Factors responsible are discussed. Some are preventable whilst others need further research.

Abstract
Arteriovenous fistulas constructed from preserved (frozen) allograft veins provided vascular access for maintenance hemodialysis in 14 patients with inadequate vasculature for conventional autogenous fistulas. Electromagnetic flows ranged from 200 to 250 cc/min. Dialysis flow of 200 cc/min were accomplished consistently. The allografts were useable for dialysis much earlier than autogenous A-V fistulas. Arteriography demonstrated a wide vasculature channel very suitable for dialysis needles. Allografts seemed superior to bovine heterografts in both patency and susceptibility to infection. Scanning electron microscopy revealed smoother initimal surfaces if the donor received small amounts of heparin systemically while the veins were being removed. Allograft veins appear to be a useful alternative means of vascular access for hemodialysis.

Abstract
An attachment for a standard intravenous infusion set is described. It allows delivery of carbohydrate and amino-acid solutions in a manner that favours maximum utilization and reduces the risks of metabolic complications. It also permits, with ease, repeated alterations of infusion regimes when this is considered necessary.

Abstract
H. pylori infection occurs worldwide. Approximately 50% of the world population is infected with this organism. A cross-sectional study was conducted on 81 dyspeptic patients attending at Dhaka Medical College Hospital, for diagnostic endoscopy. H. pylori infection was measured by three invasive methods: culture, rapid urease test & histopathology. Among study patients maximum (34.57%) H. pylori infected were in 21-30 years age group, bearing male female ratio 1: 92.86. Forty four (54.32%) out of 81 were culture positive, 61 (75.31%) were rapid urease test positive and 62 (76.54%) were histopathology positive. By using 'gold standard' definition, 64 (79.02%) were H. pylori infected, 17 were un-infected. Finally comparing among three invasive methods, all are highly sensitive and specific to diagnose H. pylori infection. DOI: 10.3329/fmcj.v5i1.6809Faridpur Med. Coll. J. 2010;5(1):21-24

Abstract
1. The iodide space in rabbit brain varies greatly depending on the conditions under which it is determined.2. When (131)I(-) only is used the iodide space 4 hr after administration of the marker is of the order of 2%. The iodide content of the cerebrospinal fluid (c.s.f.) is about 1% of that of the serum.3. Depression of the active iodide transport by perchlorate increases the space to 8.2% and the iodide content of the c.s.f. to 26% of that of the serum.4. The active iodide transport can also be depressed by saturation with unlabelled iodide. Up to a serum iodide concentration of 5 mM the space determined after 5 hr remained constant at 2.7%. The iodide space grew when the serum iodide content was enhanced from 5 to 20 mM, to become constant at a value of 10.6% on further increase of the serum iodide (up to 50 mM). The iodide content of the c.s.f. increased in a similar manner as the space with the iodide concentration of the serum to about 1/3 of the serum concentration. The iodide space of the muscle was independent of the plasma iodide content.5. From 4 to 8 hr after administration of (131)I(-) alone or with unlabelled iodide (to a serum concentration of 15 mM) the iodide space remained relatively constant.6. When (131)I(-) was administered in the fluid with which the ventricles were perfused an iodide space of about 7% was attained after about 5 hr.7. In experiments in which (131)I(-) was administered intravenously and the sink action of the c.s.f. was eliminated by perfusion of the ventricles with a perfusate containing as much (131)I(-) as the plasma, the iodide space was 10.2%. When in addition active iodide transport was depressed by perchlorate the space increased to 16.8%.8. Intravenous administration of labelled and unlabelled iodide (to a serum concentration of 20-40 mM) and ventricle perfusion with the same concentration of (131)I(-) and unlabelled iodide as in the plasma yielded an iodide space of 20.8%. In similar experiments the iodide concentration of the perfusate was so adjusted that after 5 hr perfusion its iodide content hardly changed during the passage through the ventricles. Under these conditions the iodide concentration of the extracellular and perfusion fluids can be considered to be near equal. The iodide space computed on the basis of the iodide content of the outflowing fluid was 22.5%.9. The large iodide space could be equated with the extracellular space if the iodide remained extracellular. This seems to be the case in the muscle where the iodide space is similar to the inulin space.10. The large effects on the iodide space of perchlorate and saturation with unlabelled iodide in experiments in which the marker was administered intravenously and in the perfusate (7 and 8) suggests the presence of an active iodide transport from the brain extracellular fluid into the blood over the blood-brain barrier.

Abstract
1. Progesterone treatment (50 mg/kg) in ovariectomized rats antagonizes the effects of stilboestrol 100 mug/kg on the vaginal mucosa and uterine weight; but the sensitivity to acetylcholine, oxytocin and 5-hydroxytryptamine is increased by factors 4, 11 and 3, respectively.2. In intact animals a similar progesterone treatment (50 mg/kg) antagonizes the effects of stilboestrol 100 mug/kg on vaginal smears, uterine weight and uterine sensitivity. The uterine sensitivity to acetylcholine, oxytocin and 5-hydroxytryptamine is, however, decreased by a factor of 2, 1.4 and 17.7, respectively.3. These experiments show that the ovary is essential for the desensitizing effects of progesterone. The suggestion is put forward that another substance is released from the ovary by progesterone.
