Aquaporin-1 (AQP1) water channels are expressed widely in epithelia and capillary endothelia involved in fluid transport. To test whether AQP1 facilitates water movement from capillaries into the peritoneal cavity, osmotically induced water transport rates were compared in AQP1 knockout [(-/-)], heterozygous [(+/-)], and wild-type [(+/+)] mice. In (+/+) mice, RT-PCR showed detectable transcript...

It has been well known that inert foreign materials, introduced into the peritoneal cavity, are easily and rapidly absorbed by the lymphatic vessel on the surface of the diaphragm as cited briefly in Lymphatics, Lymph and Lymphoid Tissue by Y o f f e y and C o u r t i c e (1956) or in Physiologie und Pathologie des Lymphkreislaufes by R u s z u y a k, F o l d i and S z a b ô (1957). The pinocyt...

Hydatid disease, caused by Echinococcus granulosus, is a common parasitic infection of the liver. Disseminated intra-abdominal hydatid disease may occur following rupture of the hydatid cyst into the peritoneal cavity, producing secondary echinococcosis. Rarely cyst may develop de-novo in the peritoneal cavity without involvement of any other intra-abdominal organs. We present a unique case of ...

Almost all cases of abdominal pregnancy follow early rupture or abortion of a tubal pregnancy into the peritoneal cavity. In very rare cases of uterine rupture the fetus may be extruded into the peritoneal cavity while the placenta remains functional within the uterus and the gestation continues as a uteroabdominal pregnancy [1]. We present a rare case of, uteroabdominal pregnancy following ute...

background: peritoneal inclusion cyst (pic) is defined as a fluid-filled mesothelial-lined cyst of the pelvis and it is most frequently encountered in women of reproductive age and rarely, they may occur in males. case presentation: a 12 year old boy was referred with a two-day history of abdominal pain. abdominal examination revealed lower abdominal tenderness. laboratory tests were normal. ab...

In our initial studies we found that naïve CCR6-deficient (CCR6(-/-)) C57BL/6 mice possessed significantly lower number of both F4/80(+) macrophages and dendritic cells (DC), but higher number of B cells in the peritoneal cavity, as compared to naïve wild type (WT) controls. Furthermore, peritoneal macrophages isolated from CCR6(-/-) mice expressed significantly lower levels of inflammatory cyt...

BACKGROUND The role of the immune system in the pathogenesis of endometriosis remains elusive. It has been shown that patients have an altered peritoneal environment with increased levels of inflammatory cytokines, activated macrophages and reduced clearance of retrogradely transported endometrial fragments. However, it is not known if this unique inflammatory situation is cause or consequence ...
