Objective: To compare the effects of collagen fiber staining between Van-Gieson staining and Masson trichrome staining of hepatic specimens in mice with Schistosoma japonicum infection.
Methods: A model of hepatic granuloma and fibrosis was established by infecting mice with S. japonicum cercariae, then the hepatic specimens were taken and Van-Gieson staining and Masson trichrome staining were performed. Eventually, the area of granuloma and fibrosis were measured by imaging analysis software.
Results: When the time of staining was 3-7 min, there was no significant difference of the fibrosis areas between the two methods (P > 0.05); when the time of staining was more than 10 min, the staining area showed by Masson's staining was significantly larger than that showed by Van-Gieson staining, and the difference was statistically significant (P < 0.05).
Conclusion: The operation procedures of Van-Gieson staining are simpler and easier to master than those of Masson trichrome staining, therefore Van-Gieson staining is a better method to display collagen.

Background: Given the lack of models for carotid artery dissections (CAD), we aim to investigate effects of beta-aminopropionitrile (BAPN) combined with physical damage on the arterial walls of rats, and to establish a high-incidence and low-mortality CAD model.
Methods: Sixteen SPF SD rats (3-week-old) were divided into two groups. Group B was given 0.

The importance of collagen and elastin remains incompletely understood concerning tumor immunity in cancer tissues. This study explored the clinical significance of collagen and elastin deposition on tumor immunity in advanced colorectal cancer patients. The collagen and elastin contents were assessed simultaneously using elastic van Gieson (EVG) histochemical staining.

Marfan syndrome (MFS) is a systemic connective tissue disorder stemming from mutations in the gene encoding Fibrillin-1 (Fbn1), a key extracellular matrix glycoprotein. This condition manifests with various clinical features, the most critical of which is the formation of aortic root aneurysms. Reduced nitric oxide (NO) production due to diminished endothelial nitric oxide synthase (eNOS) activity has been linked to MFS aortic aneurysm pathology.

An abdominal aortic aneurysm (AAA) is described as a gradual and localized permanent expansion of the aorta resulting from the weakening of the vascular wall. The key aspects of AAA's progression are high proteolysis of the structural elements of the vascular wall, the depletion of vascular smooth muscle cells (VSMCs), and a chronic immunoinflammatory response. The pathological mechanisms underpinning the development of an AAA are complex and still unknown.

Aim: To investigate the influence of type 2 diabetes (T2D) and hyperglycaemia on blood vessels and angiogenic markers in the dental pulp.
Methodology: Extracted non-carious permanent molar teeth were collected from patients with well-controlled T2D (n = 10) and non-T2D (controls) (n = 10). The pulp was examined qualitatively using haematoxylin and eosin and Van Gieson stains.
