[ effect of aquae extract of Aloe vera on synaptophysin expression after spinal cord compression in adult rats]

Spinal cord compression is one of causes for disability. Nowadays to minimize these complication is a goal. The effect of aquae extract of Aloe vera on motoneuron death and chemical neurotransmitter for cell signaling in paralysed rats. We used 32 female rats from Razi institute. They were randomized divided to 4 groups: 1- control 2- treated with Aloe vera 3- treated with Aloe vera + spinal cord compression by clips aneurysm 4- control +spinal cord compression by clips aneurysm. Perituneal injection continued for 4 weeks [every day]. We used 2.5 mg/kg aquae extract of Aloe vera. Compression has caused, motoneuron in ventral horn decreases with cavitation. In second group these changes are less [p

Electromyographic analysis of shoulder impingement syndrome versus normal subjects

Altered muscle activity in the scapulothoracic and glenohumeral muscles is commonly believed to be a factor contributing to shoulder impingement syndrome [SIS], then, the aim of the study was to determine and compare the activity pattern of the shoulder muscles in subjects with and without SIS. In this case-control study, 9 female subjects with shoulder impingement syndrome and 13 matched healthy female subjects were participated voluntarily by simple random sampling. Surface electromyography of serratus anterior, pectoralis major, upper trapezium, lower trapezium, posterior deltoid, anterior deltoid muscles of dominant side were recorded during Diext and Diflex movement. Muscle activities were processed and compared in subjects with and without SIS. Non parametric test [Mann-Whitney Test]] was used for data analysis. In both movement patterns, all muscles of the patient showed a greater normalized RMS than healthy group but this increase was statistically significant in anterior deltoid [p=0/003, p=0/04], pectoralis major [p=0/01, p=0/02], serratus anterior [p=0/01] and posterior deltoid [p=0/01] during Diext and in lower trapezium [p=0/005,p=0=006] and pectoralis major [p=0/01] during Diflex. The results of this study indicate that patients with impingement symptoms show abnormal muscle activity. The findings support the theory that shoulders impingement may be related to altered muscle activity in the scapulothoracic and glenohumeral muscles
