T-cell signature cytokines distinguish pulmonary sarcoidosis from pulmonary tuberculosis

Sarcoidosis is a systemic inflammatory disorder characterized by tissue infiltration due to mononuclear phagocytes and lymphocytes and associated noncaseating granuloma formation. Pulmonary sarcoidosis (PS) shares a number of clinical, radiological, and histopathological characteristics with that of pulmonary tuberculosis (PTB). Due to this, clinicians face issues in differentiating between PS and PTB in a substantial number of cases. There is a lack of any specific biomarker that can diagnose PS distinctively from PTB. We compared T-cell-based signature cytokines in patients with PS and PTB. In this study, we proposed a serum biomarker panel consisting of cytokines from cells: T helper (Th) 1 [interferon-gamma (IFN-γ); tumor necrosis factor-alpha (TNF-α)], Th9 [interleukin (IL)-9], Th17 [IL-17], and T regulatory (Treg) [IL-10; transforming growth factor-beta (TGF-β)]. We performed the principal component analysis that demonstrated that our serum cytokine panel has a significant predictive ability to differentiate PS from PTB. Our results could aid clinicians to improve the diagnostic workflow for patients with PS in TB endemic settings where the diagnosis between PS and PTB is often ambiguous.     

Effect of garlic and cabbage on healing of gastric ulcer in experimental rats

The effect of garlic (Allium sativum) and cabbage (Brassica oleracea var. capitata) extracts on the healing of gastric ulcer in experimental rats has been investigated. Thirty-three albino male rats (115 ± 4 g B.Wt. each) were used and divided into 6 groups (n = 6 rats); one was used as a negative control while the others were given aspirin orally (200 mg/kg B.Wt.). One of these groups was employed as a positive control and the others were administrated with 150 or 300 mg/kg B.Wt. doses of garlic and cabbage juice for 7 days. The length of the gastric ulcer, the volume of gastric juice, the total acidity, the pH value, the total bacterial count, and the histopathological changes of the stomach were examined. Results revealed that oral administration with both tested plant extracts reduced the length of gastric ulcer, the total acidity, the volume of gastric juice, the bacterial count, and the histopathological changes caused by aspirin. On the other hand, both aqueous plants extract increased the pH value of gastric juice. It is concluded that, garlic and cabbage extract could be used for healing acute gastric ulcer.
