Ulcerative colitis (UC) is a common refractory and life-long disease (Sedghi, 2016 Murakami et al., 2018). Tude gastroenteritis, fever, diarrhea, rectal bleeding, mucus in stools, sense of urgency for bowel movements, and abdominal pain (Xu et al., 2016). The occasional eude arthritis, iridocyclitis, episcleritis, erythema nodosum, liver dysfunction, and skin lesions. The etiology of UC remains unknown. Modern researchers believe that the etiology involves genetic factors, environmental factors, microbial infections, and other factors (Dulai and Jairath, 2018). Some researchers consider UC to be an autoimmune disease (Wiese et al., 2016 Kim et al., 2017). Currently, UC cannot be completely cured and life-long treatment is needed in most cases (Nowarski et al., 2015). Further, 20–30% of patients with severe UC require surgery as a part of their treatment (Lanzoni et al., 2008). Anti-inflammatory treatment with drug...

Pentabarbital (CAS number), alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO), triglyceride (TG), cyclic guanosine monophosphate (cGMP), cyclic adenosine monophosphate (cAMP), sodium-potassium adenos... Preparation of Drug Suspension Solution Baicalin, baicalein, and sulfasalazine were diluted in CMC-Na and the following suspension solutions were constructed: baicalin (100 mg kg-1), baicalein (100 mg kg-1), young Scutellaria baicalensis with a 4:1 ratio of baicalin to baicalein (YSR 100 mg kg-1), withered Scutellaria baicalensis with a 1:1 ratio of baicalin to baicalein (WSR 100 mg kg-1), and sulfasalazine (100 mg kg-1). Solutions were stored in the dark at 4 °C and were used within 5 days of preparation. The proportional relati... Experimental Animals and Grouping Fifty-six Sprague-Dawley (SD) rats (180–220 g) were housed in an SPF-level laboratory. The room temperature was regulated at 18–25°C with 50 ± 5% humidity. A 12 h light/dark cycle was implemented and the rats were fed a standard diet and given free access to water. Animal welfare was ensured and experimental procedures were performed in accordance with the Guide for the Care and Use of Laboratory Animals (Ministry of Science and Technology of China, 2010). This study was approved by the Anima... See full list on Changes in Clinical Symptoms and Signs Before the experiment, all rats were active and their fur was smooth, white, and clean. Their diets, stools, and urine were all normal. At the beginning of the experiment, the rats in the NC group exhibited no obvious abnormalease in their weights (Yi et al., 2010). In all other groups, during the initial 10 days of feeding a high-sugar and higheased water intake and urination. The urine was yellowish on the fasting days, whi... Temperature Changes in the 48 H After Drug Administration As shown in Figure 3B, within 48 h of the first drug dose, the average body temperature of the NC group fluctuated around 36.6°C. Compared with the NC group, the body temperature of the eased (P < 0.05). The model group reached a maximum temperature of 38.9°C before stabilization of temperature at 38.3°C. Compared with the model group, the average body temperatures of the drug groups were significantly reduced to different degrees (P < 0.01). The results indi... Organ Indices As shown in Table 1, the tissues and organs of the NC group were observed to be normal. The livers, spleens, lungs, and kidneys of the model group and the self-healing group had different degrees of congestion, edema, degeneration, necrosis, and inflammation. The organ indices for each organ in the model group was significantly higher than in the NC group (P < 0.05). The organ indices of the treatment groups were significantly lower than those of the UC group. The rats in the UC group exhibit... See full list on We examined the therapeutic effects and mechanisms of action of baicalin and baicalein in the treatment of UC model rats. We found that the two drugs have significant therapeutic differeneased body temperature, weight loss, inflammation, lipids, and liver disturbances. Further, the findings indicate that there are different mechanisms underlying the effects of each drug on inflammatory cytokines in UC. Our study shows that the basic treatment of intestinal diseases such as UC is through anti-inflammatory pathways. The mechanism of action is likely through regulation of the Th17/Treg balance and control of intestinal bacteria. Baicalin, more than baicalein, inhibits inflammatory factors IL-1β and IL-6 and activates the MAKP and NF-κB signaling pathways to induce IL-17 production. The antibacterial and antiviral effects of baicalin and baicalein underlie the treatment effects of these drugs in UC. In this experiment, YSR treatment was found to be supe... See full list on Scutellaria baicalensis is a herbal medicine traditionally used for the treatment of UC. The main components of Scutellaria baicalensis are baicalin and baicalein. In this study, we tested each component separately and in combination for the treatment of UC. Baicalin, baicalein, and a combination of the two drugs, had significantly different effects on UC. We found that baicalin and baicalein have different advantages in treating UC, and a combination of the two drugs provides more comprehensive treatment specifically, YSR was the most effective treatment. The proportion of baicalin in YSR is higher than the proportion of baicalein, consistent with the natural proportion of baicalin and baicalein in young Scutellaria baicalensis. This study compared the mechanisms of action of baicalin and baicalein based on pharmacodynamic indicators and evaluation of chemical composition using metabolomics techniques, UPLC-MS/MS, and traditional pharmacological indicators. It was found that compa...
