Composed wall with site laying reinforcing rib is composed of reinforced concrete rib, girtstrip and filling brickwork. This kind of wall is energy-saving, environmental-friendly and of good earthquake resistant performance. It is suitable to village building structure. In this paper, the load carrying capability and failure mode of this kind of composed wall under the effect of vertical load, the maximum bearing capacity of the wall and its influencing factors are mainly introduced.

Introduction: Campylobacter rectus and Provetella intermedia bacteria as the main etiology causes of periodontal disease. One of the locally synthesized antimicrobials that is widely used for the treatment of periodontitis is Chlorhexidine, however this drug has side effects when used continuously. To overcome this, an alternative periodontitis therapy with medicinal plants is needed. This study aims to determine the effectiveness of hydrogel Aloe vera antibacterial concentrations of 2.5%, 5%, 10% and 20% in the bacteria Campylobacter rectus and Provetella intermedia. Methods: This study was a laboratory experimental study with posttest only control group design in vitro. The samples were Campylobacter rectus and Provetella intermedia. The number of groups in this study was six. The sample size was determined by Federer's formula and obtained four replications for each group. Data collection by measuring the inhibition diameter using a slide caliper. Data were analyzed using oneway ANOVA and posthoc LSD. Results: The results showed that there was a difference in the diameter of the hydrogel Aloe vera inhibition with a concentration of 2.5%, 5%, 10%, 20% and a positive control for Campylobacter rectus and Provetella intermedia bacteria. Conclusion: This study concluded that there is an antibacterial effectiveness of hydrogel Aloe vera in concentrations of 2.5%, 5%, 10% and 20% on Campylobacter rectus and Provetella intermedia bacteria.

Background: Anti-inflammatory role of Aloe vera gel is well established. Diclofenac is extensively used for acute and chronic inflammation. The present study was conducted to compare dried Aloe vera gel and diclofenac effects on sodium and potassium balance in hypertensive rats. Material and Methods: This experimental study was conducted at Sargodha Medical College from May to November 2016. Twenty-four healthy male Sprague Dawley rats 7-8 weeks of age were included in study. Any unhealthy-looking rat was excluded from the study. Rats were equally and randomly divided into four groups Normal control (group A), Model control (group B), Aloe vera (group C) & Diclofenac (group D). Hypertension was induced by a 20 % sucrose diet in all groups except group A in 8 weeks’ time. Group B, C & D received distilled water and Aloe vera dried gel 400 mg/kg & diclofenac powder 12 mg/kg body weight respectively orally between 8 to 10 weeks. Serum and urine analysis was performed for hematocrit, sodium, and potassium concentrations at zero, eight and ten weeks. Twenty-four-hour urinary sodium excretion was calculated. Data was analyzed using Graph Pad Prism version 6. Result: After 2-week administration of aloe vera and diclofenac powder, serum potassium significantly decreased in Group C (p <0.001) while increased in Group B and D (p <0.001) as compared to group A. Urinary sodium concentration and excretion increased significantly in Group C (p <0.01) as compared to Group A whereas result of Group D was insignificant. No significant change in serum sodium and hematocrit of any group was observed. Conclusion: Aloe vera causes less sodium retention than diclofenac but decreases serum potassium contrary to the effect of diclofenac in hypertensive rats.
