Background: There are numerus techniques and agents in use for reducing peritoneal adhesion formation. But in this research we believe this is the first research to reveal that contractubex (allium cepae, sodium heparin, and allantoin mixture) is reducing formed peritoneal adhesions. So it may be used to reduce the number of re-laparotomies/re-laparoscopies caused by peritoneal adhesions related complications.
Objective: To evaluate the effects of contractubex (CT) in a rat model of postoperative peritoneal adhesion (PPA).
Methods: Fifty rats were divided into four equal groups. In group 1, 1 g of CT was injected into the peritoneal cavity. In group 2, adhesions were generated. In group 3, adhesions were generated, and 1 g of CT was immediately applied into the peritoneal cavity. In group 4, adhesions were generated, and at postoperative d 7, 1 g of CT was applied into the peritoneal cavity. In group 5, adhesions were generated, and at postoperative d1, 3, 5, and 7, 1 g of CT was applied into the peritoneal cavity. The adhesions were scored both macroscopically and microscopically.
Results: The mean macroscopic adhesion scores in groups 1-5 were 0 ± 0, 2.9 ± 0.21, 2.3 ± 0.54, 0.8 ± 0.63, and 2.2 ± 0.72, respectively (P < 0.0001); the mean microscopic values were 0 ± 0, 2.8 ± 0.42, 2.8 ± 0.42, 0.6 ± 0.52, and 2.3 ± 0.48, respectively (P < 0.0001). The mean macroscopic adhesion score in group 4 was lower than that in group 2 (P = 0.001). The mean macroscopic adhesion scores in groups 3 and 5 were higher than those in group 4 (P = 0.045 and P = 0.038, respectively) but did not significantly differ from those in group 2 (P = 0.171 and P = 0.124, respectively).
Commentary: A single dose of contractubex did not prevent PPA formation but did diminish the amount of formed PPAs.

During cancer peritoneal metastasis (PM), conventional antigen-presenting cells (dendritic cells, macrophages) promote tumorigenesis and immunosuppression in peritoneal cavity. While intraperitoneal immunotherapy (IPIT) has been used in clinical investigations to relieve PM, the limited knowledge of peritoneal immunocytes has hindered the development of therapeutic IPIT. Here, a dendritic cell-independent, next-generation IPIT is described that activates peritoneal cavity B (PerC B) cell subsets for intraperitoneal anti-tumor immunity via exogenous antigen presentation.

Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.

How macrophages in the tissue environment integrate multiple stimuli depends on the genetic background of the host, but this is still poorly understood. We investigate IL-4 activation of male C57BL/6 and BALB/c strain specific in vivo tissue-resident macrophages (TRMs) from the peritoneal cavity. C57BL/6 TRMs are more transcriptionally responsive to IL-4 stimulation, with induced genes associated with more super enhancers, induced enhancers, and topologically associating domains (TAD) boundaries.

Currently, Ovarian Cancer (OC) is the most lethal gynecological malignancy. In most patients, it progresses without clinical signs or symptoms, leading to a late diagnosis when it has already spread in the peritoneal cavity as peritoneal carcinomatosis (PC). To date, OC PC management is based on cytoreductive surgery to remove the macroscopic disease, followed by chemotherapy.

PEPITEM is an immune-modulatory peptide that effectively regulates inflammation and mitigates immune-mediated inflammatory diseases (IMIDs). Here, we identify two independently active tripeptide pharmacophores within PEPITEM and engineered peptidomimetics with enhanced pharmacodynamic properties. These peptidomimetics regulate T-cell trafficking in vitro and reduce T-cell, neutrophil and macrophage numbers in the inflamed peritoneal cavity in vivo.
