Aloe vera (AV) is popular and has been commercialized as a beauty product, laxative, herbal medicine, the antimicrobial activity of AV is proven. The antiviral activity of AV however, has not been well documented except for a handful reports. Till date extraction of AV compounds is popularized using …

The present study was undertaken to evaluate the protective effect of aqueous leaf extract of Aloe vera (ALEAV) in animal model (wistar albino rats) through macroscopic and histopathological study of the colon after inducing ulcerative colitis by usage of acetic acid. 30 healthy albino rats of either sex 150-200g body wt. and 2-4 months age groups were divided into five groups (six in each). Group 1 was normal control group receiving vehicle 1ml of normal saline transrectally (negative control). Group 2 was ulcerative colitis control which was treated with normal saline. Group 3 & 4 were administered aqueous leaf extract of Aloe vera suspension(test drug) 150,300mg/kg bodyweight dose orally for 10 days respectively. Ulcerative colitis was induced on 10 th day. Group 5 was administered prednisolone(1mg/kg) orally for 3 days. On the 3 rd day ulcerative colitis was induced by transrectal administration of 1 ml of 4% acetic acid solution. In all the groups, animals were observed for decrease in bodyweight, stool consistency and rectal bleeding i.e Disease Activity Index for 48 hours after inducing ulcerative colitis. After 48 hours the rats were sacrificed by high dose of ether anaesthesia and a piece of colonic segment(10cm in length) were resected out and subjected to macroscopical study(colon mucosal index) and microscopic evaluation. ALEAV at 150 mg/kg produced significant improvement in macroscopic score in comparison to disease control (group 2) which is comparable to that of normal control (group 1) in ulcerative colitis model. Histopathological studies showed significant dose dependent decrease in lymphoid hyperplasia, neutrophilic infiltration, crypt damage and submucosal inflammation in ALEAV treated group (150 and 300 mg/kg b.w) in comparison to disease control.

Our previous study has suggested that the crude polysaccharide obtained from Laminaria japonica by acid assisted extraction (LP-A) have significant bile acid-binding capacity, which probably ascribed to its specific structure characterization. The relationship between structure characterization and bile acid-binding capacity of the purified LP-A fractions are still unknown. This paper conducted a comparison study on the structure characterization and bile acid-binding capacity of three LP-A fractions (LP-A4, LP-A6, and LP-A8). The results indicated that LP-A4, LP-A6, and LP-A8, characterized as mannoglucan, fucomannoglucan, and fucogalactan, had significantly different structure characterization. Furthermore, the bile acid-binding capacity of LP-A8 was obviously higher than the other fractions, which may be attributed to its highly branched structure, abundant sulfate, fucose, and galactose in chemical composition and denser interconnected macromolecule network in molecular morphology. This study provides scientific evidence for the potential utilization of LP-A8 as an attractive functional food supplement candidate for the hyperlipidemia population.

Fucoidan, a natural sulfated polysaccharide, displays various biological activities including antioxidant properties. We examined the neuroprotective effect of fucoidan against transient global cerebral ischemia (tGCI) in high-fat diet (HFD)-induced obese gerbils and its related mechanisms. Gerbils received HFD for 12 weeks and fucoidan (50 mg/kg) daily for the last 5 days during HFD exposure, and they were subjected to 5-min tGCI. Pyramidal cell death was observed only in the CA 1 area (CA1) of the hippocampus in non-obese gerbils 5 days after tGCI. However, in obese gerbils, pyramidal cell death in the CA1 and CA2/3 occurred at 2 days and 5 days, respectively, after tGCI. In the obese gerbils, oxidative stress indicators (dihydroethidium, 8-hydroxyguanine and 4-hydroxy-2-nonenal) were significantly enhanced and antioxidant enzymes (SOD1 and SOD2) were significantly reduced in pre- and post-ischemic phases compared to the non-obese gerbils. Fucoidan treatment attenuated acceleration and exacerbation of tGCI-induced neuronal death in the CA1–3, showing that oxidative stress was significantly reduced, and antioxidant enzymes were significantly increased in pre- and post-ischemic phases. These findings indicate that pretreated fucoidan can relieve the acceleration and exacerbation of ischemic brain injury in an obese state via the attenuation of obesity-induced severe oxidative damage.
