Introduction: Many new objective tests to assess the function of specific structures of the vestibular organ are currently adopted in vestibular clinics. One of the objective assessments include the video head impulse test (vHIT) where gain & velocity responses of eye relative to the head movements are recorded using an infrared camera. Methods: Thirty normal hearing subjects age between 18 to 25 years old participated in this study. At least ten Lateral, Left Anterior Right Posterior (LARP), and Right Anterior Left Posterior (RALP) responses were recorded for each participant by making small and rapid unpredictable head movements. Results: The average velocity gain for Lateral responses at 40 ms, 60 ms and 80 ms were 1.05 ± 0.003, 1.03 ± 0.002 and 1.01 ± 0.003 respectively. The LARP average velocity regression were 1.01 ± 0.24 for Left Anterior and 1.05 ± 0.25 for Right Posterior, with an average gain asymmetry of 5.13%. The RALP average velocity regression were 1.08 ± 0.31 for Right Anterior and 1.12 ± 0.30 for Left Posterior, with an average gain asymmetry of 5.87%. One sample T-test were conducted to compare Lateral responses to a previous study by Mossman et al. (2015) where significant differences in velocity gain at 60 ms and 80 ms between studies were found where, t (59) = 5.56, p <0.01 and t (59) = 2.86, p < 0.01 respectively. Conclusion: This indicates the importance of establishing on-site norms for every clinical settings as techniques used and equipment differences could affect the results.

Aframomum melegueta (Zingiberaceae) seeds are used in West Africa, as a remedy for variety of ailments such as stomach ache, snakebite, diarrhea and anti-inflammatory properties. The hypoglycaemic effects of crude leaf extract of Aframomum melegueta on the treatment of alloxan induced diabetes in male rats and non-diabetic rats (control) were examined in this study. Results obtained from the experiment showed that the elevated blood glucose level caused by oral administration of 250 mg / kg body weight of alloxan was reduced significantly (p < 0.01) by oral administration of Aframomum melegueta leaf extract doses of 50, 100 and 200 mg/kg with the exception of 20 mg/kg when compared to control groups. The non-diabetic groups that received the extract showed reduction in blood sugar level as the dose increases when compared to their control group. There was a final weight gain and organ restoration for both the diabetic and non-diabetic rats after treatment when compared with their controls. This study showed that the extract have hypoglycemic and prophylactic effects.

Objective To investigate the differentiation of mesenchymal stem cells(rMSCs) of young rat into neuron-like cells with Ligustrazin hydrochloride. Methods rMSCs were separated from femurs marrow flushed out with DMEM(low glucose) by using a needle and syringe, then planted in plastic culture flask. Through expanded to 5 passages, rMSCs were induced to differentiate into neuron-like cells with Ligustrazin hydrochloride. Anti-neurofilament(NF-M), nestin, neuron-specific enolase(NSE), MAP-2,GAP-43 and glial fibrillary acidic protein(GFAP) antibodies were detected by immunohistochemistry. Results rMSCs were comprised a single phenotypic population and displayed a fibroblast-like morphology after 5 passage in culture. With 10*!?g/L bFGF pre-induce for 24*!h, then the medium was replaced with induction medium containing Ligustrazin hydrochloride. The induced-rMSCs exhibited neuronal morphological characteristics from the first half an hour to 5*!h. The neuron-like cells expressed NF-M, NSE, MAP-2,GAP-43 and nestin positive, but didn't express glial astrocyte marker GFAP.Conclusion rMSCs can be induced to differentiate into neuron like cells with Ligustrazin hydrochloride in vitro.

Objective To investigate the relationship between the ultrastructural features combined with the expression of connexin ( Cx43 ) protein in uterine junction zone and pathogenesis of adenomyosis.Methods From Nov. 2008 to Nov. 2009, 30 patients with adenomyosis (including 14 cases with proliferative endometrium and 16 cases with secretory endometrium) as study group matched with 30 women with cervical intraepithelial neoplasia (GIN) Ⅲ treated by hysterectomy as control group were enrolled in this study in Affiliated Hospital to Inner Mongolia Medical College. The expression of Cx43 in uterine junction zone of patients with adenomyosis was detected by immunohistochemisty staining. The ultrastucture of eutopic endometrium, uterine junction zone and outer 1/3 myometrium in both groups without history of dilatation and curettage, C-section and uterine surgery were observed by using transmission electron microscopy. Results ( 1 )The expression of Cx43 in proliferative and secretroy uterine junction zone were 0.133 ±0.018 and 0.137 ± 0.021 in study group and 0.154 ±0.016 and 0.141 ±0.018 in control group,which reached statistical difference (P ＜0.05). However, it didn't show significant expression of Cx43 between proliferative and secretory uterine junction zone in study or control group ( P ＞ 0.05 ). The expression of Cx43 in proliferative and secretory of eutopic endometrium of 0.067 ± 0.017 and 0.062 ± 0142 in study group were significantly lower than 0.094 ±0.005 and 0.080 ±0.005 in control group. It didn't show statistical difference of Cx43 expression between proliferative and secretroy eutopic endometrium in both group. The expression Cx43 in outer myometrium of proliferative phase were 0.184 ± 0.022 in study group and 0.188 ± 0.028 in control group, which did not show significant difference (P ＞0.05). It also did not exhibit statistical difference of Cx43 expression in outer myometrium of secretory phase (0.178 ± 0.022,0.191 ± 0.025,P ＞0.05). (2) Morphological changes: the area of uterine smooth muscle cells of the uterine junction zone of (24. 3 ± 1.6) μm2 in study group were significantly increased than (21.8 ±2.0)μm2 in control group (P ＜ 0.01 ). The length of the cell membrane dense plaques of (1.07 ± 0. 17 )μm in study group was significantly increased than (0.71 ±0.07) μm in control group (P ＜0.01 ). The myocytes exhibited cellular hypertrophy and disordered arrangement and fewer caveolae. There was cylindrical and dentate, chromatin margination, more heterochromatin in which muscle cells of nuclear surface of the uterine junction zone. Less cytoplasmic myofilaments and more intermediate filaments. Mitochondria were increased,the volume increased significantly vacuolization. The rough endoplasmic reticulum and Golgi apparatus were more prominent. Otherewise, mast cells and fibroblasts were close and glandular epithelial cells showed desmosome connection which villus thickening and dense. All features were more prominent at the junctional zone. Conclusions The down-regulation of Cx43 expression and ultrastructure changes in the junction zone might play an important role in pathogenesis of adenomyosis.
