The increased prevalence of gall stones in Crohn's disease is thought to be related to depletion of the bile salt pool due either to terminal ileal disease or after ileal resection. This study was designed to examine whether this hypothesis is correct and explore alternative explanations. Two hundred and fifty one randomly selected patients (156 females, 95 males, mean age 45 years) were interv...

Gall bladder motor function is impaired in some patients with diabetes. It has been suggested that the abnormalities of gall bladder motility are confined to those patients with autonomic neuropathy. Erythromycin, a motilin receptor agonist, causes gall bladder contraction in both normal subjects and patients with gall stones with impaired gall bladder emptying. The effect of erythromycin on ga...

Gall bladder is more likely to perforate in cases of obstruction leading to raised intra luminal tension. Non obstructive cholecystitis is unlikely to result in perforation. Perforation complicating acute acalculus cholecystitis is often seen in association with acute infections like pneumonia, viral influenza, and in particular with typhoid where the causative organism Salmonella typhii multip...

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,...

Purpose: Objective of the study was to find out if there is any relation of number, size and type of gall stones and patient’s lipid profile with the occurrence of gall bladder carcinoma (GBC) as presence of gall stones is considered to be the most important risk factor for gall bladder cancer. Methods: 200 specimens of post-cholecystectomy gallbladder were studied. The number, size and type of...

Root-knot nematode-susceptible melons (Cantaloupe) were grown in pots with varying levels of Meloidogyne incognita and were compared to susceptible melons that were grafted onto Cucumis metuliferus or Cucurbita moschata rootstocks. In addition, the effect of using melons as transplants in nematode-infested soil was compared to direct seeding of melons in nematode-infested soil. There were no di...

A severe root rot of tomato caused by Meloidogyne incognita and Rhizoctonia solani was associated with nutrient mobilization into gall tissue and root exudation. Root decay did not develop when root exudates were continuously removed by leaching. When leachates were collected from M. incognita-infected and control roots and applied to roots of tomatoes inoculated with R. solani alone, roots rec...

The actual activity of ionised calcium (Ca2+) in gall bladder bile determined with an ion-selective electrode was significantly higher in patients with gall stone disease (n = 15) than in patients without gall stones (n = 10) (0.43 mmol/kg v 0.31 mmol/kg; p < 0.05). No change in the Ca2+ activity in any of the gall bladder bile samples was observed during equilibration with CO2. During titratio...

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...

herbivory is observed in different forms, one of these forms leading to gall production. among gall–inducing insects, oak gall wasps (hymenoptera: cynipidae) are found on the oak trees producing galls on certain parts of the host. in this survey, oak gall wasps were collected from oak forests in west azerbaijan in spring (2010). the occurred galls on oak trees (in spring) were collected from su...
