Background—Nitric oxide is a major neurotransmitter in non-adrenergic, noncholinergic (NANC) pathways. NANC inhibitory innervation has been shown in human gall bladder muscle in vitro; the role of nitric oxide in human gall bladder emptying however is undefined. Aims—To study the eVect of glyceryl trinitrate, a nitric oxide donor, on gall bladder emptying in healthy subjects using a randomised,...

Potentiometric titration followed by e.p.r. measurements were used to determine the midpoint reduction potentials of the redox centres of a molybdenum-containing ironsulphur protein previously isolated from Desulfovibrio gigas, a sulphate-reducing bacterium [Moura, Xavier, Bruschi, Le Gall, Hall & Cammack (1976) Biochem. Biophys. Res. Commun. 72, 782-789; Moura, Xavier, Bruschi, Le Gall & Cabra...

Galls are highly specialized plant tissues whose development is induced by another organism. The most complex and diverse galls are those induced on oak trees by gallwasps (Hymenoptera: Cynipidae: Cynipini), each species inducing a characteristic gall structure. Debate continues over the possible adaptive signi¢cance of gall structural traits; some protect the gall inducer from attack by natura...

BACKGROUND AND AIM An impaired contractility has been suggested as a contributor to the increased incidence of gallstones in liver cirrhosis, but the few studies on gall bladder emptying in cirrhotics offered contradictory results. Ingestion of a meal triggers the physiological pathway of gall bladder emptying; therefore, it was decided to analyse postprandial kinetics by investigating simultan...

Gall stone is responsible for about 1% of total small bowel obstruction, 1.2 and recurrent gall stone ileus is even more unusual. 3 Gall stone ileus is caused by the impaction of the stone in bowel lumen. It was first described in a patient examined at autopsy by Bartholin in 1654. This paper based on unusual recurrent intestinal obstructions by a gall stone. The patient presented with large bo...

Gall-bladder duplication is a rare anatomical variation, which can affect safe performance of cholecystectomy and be a cause of persistent symptoms and a need for reoperation in case of accessory gall-bladder omission. A case of successfully performed elective laparoscopic cholecystectomy in a patient with duplicated gall-bladder accidentally intraoperatively disclosed is presented. The identif...

BACKGROUND Octreotide treatment may be associated with gall stone development in up to 50% of patients with acromegaly. Two new sustained-release formulations of somatostatin analogue have been recently developed: lanreotide SR (Somatuline) and octreotide LAR (Sandostatin LAR). The incidence of gall-stone development in patients receiving these drugs has been shown to be less than 20%, but the ...

OBJECTIVE To assess the safety of confining histological examination to gall bladders with radiological and macroscopic features suggestive of cancer. DESIGN Retrospective study. Setting Department of Histopathology, National Hospital of Sri Lanka. METHOD Analysis of all cholecystectomies performed at a tertiary care hospital during a one year period. Computerised histopathological reports ...

Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...

This study discusses the percentage of Hartmann’s pouch of gall bladder and whether the Hartmann’s Pouch is an anatomical variation or pathological presentation in North Coastal Andhra Pradesh. India. Knowledge of relevant anatomy is important for the safe execution of any operative procedure,specifically in laparoscopic cholecystectomy. It has been recognized since long that misinterpretation ...
