The liver is one of the most important organs in the body and plays an essential role in the metabolism of drugs and toxins. Therefore, any damage to the liver can disrupt its function and cause various diseases. On the other hand, due to the increasing use of the medicinal herbs, in this study, the effects of hepatic protection of aqueous extracts of Humulus lupulus on liver damage induced by carbon tetrachloride in rats were investigated.

In this experimental study, 36 male Wistar rats were divided into 6 groups (n=6). Group 1 (normal control) and Group 2 (control CCl4): administered with distilled water orally for 14 days. Groups 3, 4, and 5 received 50, 100, and 200 mg/kg of Humulus lupulus extract for 14 days respectively. Group 6: administered with silymarin (as standard drug) 100 mg/kg orally for 14 days. All of the groups except group 1 received 1 ml CCl4 (1:1 v/v dissolved in olive oil) on 14th day. All animals were sacrificed and blood samples were collected to determine the biochemical parameters.

Pretreatment with a Humulus lupulus extract significantly reduced the serum levels of ALT, AST, ALP, TG, and increased the serum HDL levels, but did not have a significant effect on GGT and LDL levels.

The results of this study showed that the Humulus lupulus extract can protect the liver from damage caused by carbon tetrachloride and have beneficial effects on lipid profile.

This research investigates application of social platforms for customer engagement, and by using of gamification, presents a framework for value proposition in a platform based customer club. Audience engagement has been addressed as a wicked problem, and for this reason, Stanford approach to design research used as research method. The means for data collection has been deep interviews with two groups of managers and customers. Researchers extracted windows of values for customers and windows of income for the company. Then by proposing a gamified system for motivating customers to operate in the platform, a mechanism of keeping them as loyal customers has been developed. This research contributes theoretically by expansion of media corporate entrepreneurship and also by use of new media engaging properties to lock-in customers.

Customer engagement platforms such as gamification, co-creation and open innovation platforms have found popularity in recent decade and several industrial and service organizations are adapted to use them for marketing purposes. However, the results have been faced with challenges, that are partly raised because of lack of specific measures to evaluate performance of these platforms. The current research aims to fill the gap by identifying specific measures for evaluation of performance of these platforms in Iranian automobile industry. For this purpose, after conduct of a literature review in marketing measures, a primary set of measures have been extracted. In the second phase, a panel of experts have been used to refine the measures and to adapt them with the automobile industry. After content analysis, 82 measure identified and classified into six groups of measures, including 1) Social media measures, 2) Application-related measures, 3) Findability measures, 4) Strategy measures, 5) Public relations measures, 6) Gamification measures identified. Findings of this research can be used by strategic management, marketing and other departments of Irankhodro company that are related to performance evaluation of customer engagement platforms. the limitation of this study is that it is context-based, and generalization of the results might be considered carefully.
