Introduction The involvement of mucin, lectin, and apoptosis in colitis is still unclear. This study aimed to investigate changes in MUC2 expression, inflammation, and changes in lectin expression in colitis patients. Methods A total of 17 patients were divided into two groups including 11 hemorrhoid patients as a control group and 6 colitis patients. MUC2 mutation analysis was carried out using immunofluorescent and FISH techniques. Assessment of caspase-3, Ki-67, NF-kB, and lectin expressions was also carried out by immunofluorescent technique then analyzed by confocal laser scanning microscope. Results The MUC2, caspase-3, and lectin expressions were significantly lower in the colitis group than in the control group (p < 0.05). Conclusions It was concluded that in colitis there was a change in MUC2 expression due to changes in lectins accompanied by apoptotic defects.conclusion

Background: Mangosteen (Garcinia mangostana Linn.) is tropical fruit that known to contain bioactive compounds which has particular function as antioxidant, anti-inflammatory and antibacterial. Mangosteen rind extract is known to have high contents of xanthone compounds which have antioxidant and free radical scavenging activities. This study was done to determine the contents of xanthone derivatives using Liquid Chromatography Mass Spectrometry (LC-MS/MS) and antioxidant activity of six different maturity levels of mangosteen rind extract using Electron spin resonance (ESR). Method: Mangosteen was classified based on the maturity level by its visual characteristic and divided into six criteria of maturity. The mangosteen rinds were extracted through maceration and freeze drying method. Qualitative analysis of xanthone was obtained using LC-MS/MS. Antioxidant activity was determined using ESR spectrometer. To evaluate antioxidant activity, using 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used as free radical scavenger method. Results: The LC-MS/MS analysis showed that the highest concentrations are filled by mangosteen rind with maturity level 6. Moreover, each maturity levels of mangosteen rind extract has different g value compared to DPPH free radical. Different g value indicated the different type of free radical and decreasing g value indicated the declining intensity of free radical. The higher decreasing of g value was mangosteen rind with maturity level 4, 5 and 6. Conclusion: Mangosteen rind extract contains xanthone and its derivatives and ESR analysis showed that different maturity levels on mangosteen rind has different antioxidant activity as indicated by declining free radical intensity.

Background: Laparoscopy induces adhesion due to ischemia-reperfusion injury. However, the detail pathomechanism is poorly understood. This study aimed to investigate the impact of laparoscopy on mast cell and mesothelium morphological changes in the rat. Methods: Forty-nine males of Sprague-Dawley Rattus norvegicus were divided into four groups: a) control and b) intervention groups P1, P2, and P3 that underwent 60 min laparoscopic using carbon dioxide (CO 2) insufflation at 8, 10, and 12 mmHg groups, respectively. Serum hydrogen peroxide (H 2 O 2), catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), and oxidative stress index (OSI) levels were determined 24 h after laparoscopy. Histopathological analyses of mast cell infiltration and degranulation and mesothelium thickness in the liver, greater omentum, mesenterium, small intestine, and peritoneum were performed 7 days after the procedure. Results: H 2 O 2 , MDA, and OSI levels were significantly increased in the intervention groups compared with the control (p<0.05), while the SOD and CAT levels were decreased in the intervention groups compared with the control (p<0.05). Mast cell infiltration and degranulation were higher in the intervention groups than in control (p< 0.05), while the mesothelium thickness was significantly lower in the laparoscopic groups than in control (p<0.05). Interestingly, the decrease in mesothelium thickness was strongly associated with the increase in mast cell infiltration and degranulation (p<0.01). Conclusions: Our study shows that laparoscopy in rats increases mast cell infiltration and degranulation, which also results in and correlates with a decrease in mesothelial thickness.

Mangosteen has several important elements for biological activities such as antioxidant, anti-inflammatory, anti-bacterial and anti-cancer. There are γ-mangostin, αmangostin, flavonoids, saponins, and tannins which could stimulate the collagen deposition and accelerate wound healing process. Burn injury cause deep wound in the skin and often cause cicatrix and keloid scar on the skin. However, there is limited information about role of mangosteen in skin wound healing after burn injury. Fifty 10 week-old male rats, were subjected to burn injury using automatic temperature control. Burn injury was created by direct contact of hot plate (170°C) for 15 seconds on rats' inter scapula region. We elaborated the role of extract mangosteen in skin wound healing by applying daily gel contain with active compound derived from mangosteen. There was no significant weight change during treatment period. We observed that there was significant increase of Epidermal Growth Factors (EGF) expression in 14 as shown in immunohistochemistry and confirmed by western blot protein results. Taken together, mangosteen peel extractmediated changes in the expression of growth factors in burned rat skins. Mangosteen peel extract might have a role in the acceleration of skin wound healing.
