AIM： To analyze the hepatic and intestinal microcirculation in an animal model of liver cirrhosis and inflammatory bowel disease （IBD） and to characterize bhe anti-inflammatory action of antithrombin Ⅲ （ATⅢ） on leukocyte kinetics and liver damage. METHODS： Hepatic and intestinal microcirculation was investigated by intravital videomicroscopy. Standardized models of experimental chronic liver cirrhosis and bowel inflammation were employed. Animals were divided into four groups （n = 6/group）： controls, animals with cirrhosis, animals with cirrhosis and IBD, animals with cirrhosis and IBD treated with ATIII. RESULTS： Cirrhosis facilitated leukocyte rolling and sticking in hepatic sinusoids （1.91±0.28 sticker/μm vs 0.5±0.5 sticker/μm in controls, P〈0.05）. The effect enhanced in animals with cirrhosis and IBD （5.4±1.65 sticker/μm）, but reversed after ATIII application （3.97±1.04 sticker/μm, P〈0.05）. Mucosal blood flow showed no differences in cirrhotic animals and controls （5.3±0.31 nL/min vs5.4±0.25 nL/min） and was attenuated in animals wibh cirrhosis and IBD significantly （3.49±0.6 nL/min）. This effect was normalized in the treatment group （5.13±0.4 nL/min, P〈0.05）. Enzyme values rose during development of cirrhosis and bowel inflammation, and reduced after ATIII application （P〈0.05）. CONCLUSION： Liver cirrhosis in the presence of IBD leads to a significant reduction in mucosal blood flow and an increase in hepatic leukocyte adherence with consecutive liver injury, which can be prevented by administration of ATⅢ.

Curry leaves, scientifically termed Murraya koenigii, are renowned in South Asian cuisine for their flavor enhancement and potential health benefits, including antioxidative, anti-inflammatory, and antidiabetic properties. This study aimed to evaluate the impact of thermal processing methods on curry leaves by analysing Total Phenolic Content (TPC), Total Flavonoid Content (TFC), antioxidant activity, and metabolizing enzyme inhibition. Fresh curry leaves were subjected to thermal treatments: Oven-dried at 60˚C and Air-dried at 25˚C for 2 weeks. Extracts were prepared using Ethanol and water solvents. Results indicated that Air-dried leaves exhibited significantly higher TPC (5132.65 mg GAE/100 g) and TFC (243.13 mg CE/100 g) compared to Fresh and Oven-dried leaves. Antioxidant assays show that oven-dried curry leaves at 60˚C displayed higher results in NORS, FRAP, and TEAC assays compared to Fresh and Air-dried leaves. Ethanol extracts showed better extraction of bioactive compounds than aqueous extracts. Moreover, Lipase inhibition activity was notably high, indicating potential health benefits. This study provides valuable insights into the effects of processing methods on curry leaf extracts, emphasizing the importance of solvent selection for optimal extraction of bioactive compounds.

Background: Workers spend a significant amount of time in the workspace. Involvement of a spouse in a doctor’s workplace can take different forms and come with different intentions. Objectives: The survey aimed to determine the prevalence and extent of spousal involvement in physicians’ workplaces as well as the outcome of such involvement on doctor’ swell-being, productivity, and relationship with colleagues. Methods: This cross-sectional online survey on spousal involvement in the workplace of doctors was conducted among 83 responding doctors from July to August 2023. Results: Among the respondents, 60 (72.3%) had witnessed a doctor’s spouse being involved in the workplace. The most common reason for spousal involvement in the workplace was to protect the spouse from what they perceived as a threat 34 (54.0%). Spouse’s ignorance of boundaries in the workplace (OR: 6.09 (95% CI: 1.70, 21.79) P: 0.003) and exertion of control by the spouse (OR: 11.2 (95% CI: 2.26, 56.41) P: 0.002) were significantly associated with higher odds of inappropriate spousal involvement in the workplace, while expression of love for spouse with acts of kindness was significantly associated with a lowered odd of inappropriate spousal involvement (OR: 0.11 (95% CI: 0.03, 0.36) P: 0.0001). Conclusion: Spousal involvement in the workplace is relatively common. Ignorance of the boundaries of the workplace and exertion of control by the spouse were significant enablers of inappropriate spousal involvement in the workplace of doctors. The establishment of workplace policies that define the limits of spousal involvement in the doctor’s workplace can foster a healthy workspace environment, enhance doctors’ well-being, and improve patient care.

AIM: To analyze hepatic, mesenteric and mucosal microcirculation and leukocyte-endothelium interaction (LEI) in a rat model with liver ***: Hepatic cirrhosis was induced in Wistar rats by gavage with carbon tetrachloride, and intravital videomicroscopy was performed in liver, mesentery and small intestine mucosa. Special emphasis is given on microcirculatory and morphometric changes during cirrhotic portal ***: LEI was influenced significantly in the cirrhotic liver but not in the gut. Blood flow measurement showed significant differences among liver, main mesenteric vessels and the mucosa. The results of our study indicate that liver cirrhosis leads to alterations in hepatic and mesenteric blood flow but not in mucosal blood ***: The enhanced inflammatory response in hepatic microvessels may be caused by a decrease of antithrombin Ⅲ levels and could be responsible for disturbances of organ pathology.
