Gender is a set of common norms that pertains to the behavior of the human group, ie man and woman / girl and boy. Gender and gender are two separate concepts that are biologically and socially different. The analysis of the process of development of research and study on women is based on the continuity and reflection of the discourse of gender and relationships, based on historiographical sources, relying on the ideas and opinions of theorists and the views of many experts. The issue of gender has a field of radical studies whose historical course of development has an impact on other aspects of human life. This scientific research has been compiled with an interpretive perspective on the issue of gender and relationships. Benefiting from the opinions and thoughts of the greats in this field is not a reason to approve or reject that view from the researcher's point of view.

The rule of the most important and the important is one of the rules that has been used in Imami jurisprudence, and has not been seriously opposed by any jurist, and Imami and non-Imami jurists agree on it. Because it is not possible for everyone to correctly identify the most important criterion in determining expediency, and due to the existence of many exceptions; it is subject to a great deal of criticism, however this rule has a rational origin beyond race, language and culture and is considered efficient and necessary in all human societies. It is considered as one of the most important issues in consolidation and strategic goals of the family. The jurists and sages, while discussing privacy, information and physicality issues, pay attention to the individuals' rights in relation to privacy resulting from this rule. Cases of conflict in family law are explained according to this rule. Qualitative research has been conducted using a library method and valid scientific sources.

Dramatic increase in antibiotic-resistant bacteria highlights the need for new compounds with more effective antibacterial properties and biotechnology could be useful in producing these metabolites. The present study aimed at investigating the effects of rhamnolipid microbial surfactants in a cream-based formulation on growth inhibition of Staphylococcus aureus using in vitro and animal models.

The inhibitory effects of rhamnolipids produced by Pseudomonas aeruginosa MR01 on the growth of S. aureus were investigated by disk diffusion method. Then, the effects of dirhamnolipid compounds on the survival and morphology of bacteria were studied using estimation of colony forming units (CFUs) and scanning electron microscopy (SEM). The di-rhamnolipid-containing cream was prepared and its effects on inhibition of the bacterial growth was evaluated in in vitro and animal subjects.

Disk diffusion tests showed a minimum inhibitory value of 30mg/disk for aqueous solutions of mono- and di-rhamnolipids, and 20mg/disk and 10mg/disk for mono- and di-rhamnolipid solutions in Dimethyl sulfoxide (DMSO), respectively. The aqueous solution of di-rhamnolipids at 20mg/ml resulted in lack of viable cells of S. aureus. SEM images showed changes in spherical shape of S. aureus during rhamnolipid treatments. Di-rhamnolipid-containing cream led to inhibition of bacterial growth in vitro on agar medium. Moreover, findings in rats indicated inhibition of bacterial growth in wound areas after 20 days of treatment with the cream.

In current study, Di-rhamnolipids demonstrated inhibitory effects on the growth of S. aureus. These compounds in cream formulation could also have antibacterial effects.
