          Abstract

          This prospective study was conducted to evaluate the efficacy of sea buckthorn oil patches in treating traumatic tympanic membrane (TM) perforations. We enrolled 370 patients with traumatic TM perforations of different sizes. These patients were randomly assigned to control group and treatment group. In the treatment group, a sterile cotton patch with sea buckthorn oil was used to cover the TM perforations. In the control group, patients were treated with a sterile cotton patch. The healing rate and time were compared between the two groups. We found that the overall healing rate was significantly higher in the treatment group than in the control group. For middle and large TM perforations, sea buckthorn oil treatment led to a significant increase in the healing rate. At 2 months after injury, the duration of healing was, generally, shorter in the treatment group than in the control group ( P<0.05). In conclusion, sea buckthorn oil patches are effective in treating middle and large TM perforations, which results in increased healing rates and decreased healing time.

          Sea Buckthorn Fruit Oil Extract Alleviates Insulin Resistance through the PI3K/Akt Signaling Pathway in Type 2 Diabetes Mellitus Cells and Rats.

          Sea buckthorn fruit oil is rich in palmitoleic acid (POA), which has been reported to play roles in many metabolic processes. In this study, a sea buckthorn fruit oil (SBFO) extract was evaluated through in vitro experiments (the doses were 50, 100, 200, and 400 μM) and in vivo experiments (the doses were 100, 200, and 300 mg/kg·day) to explore its mechanism of action in the treatment of type 2 diabetes mellitus (T2DM). The results revealed that the SBFO extract effectively increased the glucose uptake from 12.23 ± 1.09 to 14.90 ± 1.48 mmol/L in insulin resistance (IR) HepG2 cells, lowered blood glucose (the reductions rates of blood glucose in groups treated with SBFO extract at 200 and 300 mg/kg·day were 10.47% and 13.79%, respectively) and improved insulin indices from -6.11 ± 0.10 to -5.45 ± 0.31 after 4 weeks treatment with SBFO extract at 300 mg/kg·day in T2DM SD rats. RT-PCR and Western blotting analyses suggested that the SBFO extract could promote the expression of phosphatidylinositol-3-kinase (PI3K) and glycogen synthesis (GS) while inhibiting the expression of glycogen synthesis kinase-3β (GSK-3β). Thus, the SBFO extract played a positive role in alleviating T2DM through the PI3K/Akt signaling pathway in HepG2 cells, and diabetic rats and could be used for the future development of functional food and dietary supplements.

            Sea buckthorn seed oil protects against the oxidative stress produced by thermally oxidized lipids.

             Alam Zeb,  Sana Ullah (2015)
            Thermally oxidized vegetable ghee was fed to the rabbits for 14 days with specific doses of sea buckthorn seed oil (SO). The ghee and SO were characterized for quality parameters and fatty acid composition using GC-MS. Rabbits serum lipid profile, hematology and histology were investigated. Major fatty acids were palmitic acid (44%) and oleic acid (46%) in ghee, while SO contains oleic acid (56.4%) and linoleic acid (18.7%). Results showed that oxidized vegetable ghee increases the serum total cholesterol, LDL-cholesterols, triglycerides and decrease the serum glucose. Oxidized ghee produced toxic effects in the liver and hematological parameters. Sea buckthorn oil supplementation significantly lowered the serum LDL-cholesterols, triglycerides and increased serum glucose and body weight of the animals. Sea buckthorn oil was found to reduce the toxic effects and degenerative changes in the liver and thus provides protection against the thermally oxidized lipids induced oxidative stress.

              Traumatic tympanic membrane perforations: a study of etiology and factors affecting outcome.

              The purposes of this study were to determine the factors involved in the spontaneous healing and to profile the various etiologies of traumatic tympanic membrane (TM) perforation.
