Distribution of transient receptor potential vanilloid-1 channels in gastrointestinal tract of patients with morbid obesity

Figure 1 Distribution of transient receptor potential vanilloid-1 channels in the gastroduodenal mucosa were demonstrated by immunohistochemical staining. A: Fundus; B: Antrum; C: Duodenum.

Figure 2 Comparison of immunoreactivity scores of foveolar cells in the fundus and antrum, mucous cells in the duodenum and antrum. A: Foveolar cells in the fundus and antrum; B: Mucous cells in the duodenum and antrum. IRS: Immunoreactivity score.

Figure 3 Duodenal mucous cells had higher immunoreactivity scores in patients with hypertension and diabetes. IRS: Immunoreactivity score; HT (+): Hypertensive; HT (-): Normotensive; DM (+): Diabetic; DM (-): Non-diabetic.
