One of the most commonly used concepts of Iranian Traditional Medicine (ITM) is movement and stasis of the body fluids, which has not yet been independently studied. In this article, ITM contents have been re-studied on this concept, and according to the dispersion of the content, classification and its therapeutic benefits have been mentioned. In this library research study, the contents related to “movement and stasis of the body fluids” have been collected from ITM textbooks and recent academic papers. In the traditional medicine references, movement and stasis of the body fluids has been discussed in a scattered manner under most of the topics and headlines of ITM. Seasonal changes, foods, medications, and severe physical and mental changes can be mentioned as important factors in movement and stasis of the body fluids. In existing literatures, some signs have been noted, which help to understand the movement or stasis of fluids or specific humor. On the other hands, movement or stasis of the fluids, which the most important of them are the four humors, can lead to physiological or pathological outcomes. The aforementioned issue is one of the most widely used concepts in ITM, which has not been scarcely discussed. Understanding the etiology of body fluids movement and stasis, its sign/symptoms, results, and complications, not only help to identify the causes of a large number of diseases, but also can help to maintain health and prevention of diseases. Moreover, this issue can be effectively and actively used in the treatment and control of treatment side effects.

Low birthweight is one the common problems of infants and one of the main health indicators of a society. Weight is one the major determinants of physical and mental development in infants, particularly preterm infants. The aim of this study is to investigate the effect of multisensory stimulation on weight gain of preterm infants.
In this double-blind clinical trial, 80 preterm infants born at 32-36 weeks gestational age, were randomly divided into two groups (control and multisensory stimulation). The intervention group received multisensory stimulation program consisting of 12-minute daily sessions, 5 times a week until the day of discharge and the control group received only the usual care. Infants were weighed every day until the day of discharge (IRCT registration code: 2016073114454N2).
FINDINGS: No significant difference was observed between the two groups of preterm infants in terms of gestational age, birthweight and sex. The difference between mean weight gain on the first day and the day of discharge was 131.6±10.1 g in the intervention group and 58.9±10.2 g in the control group. The difference between the two groups was significant (p The Results of the study revealed that using multisensory stimulation for weight gain of preterm infants is a cost-effective and effective method.

Silymarin، extracted from the seeds of milk thistle (Silybum marianum (L.) Gaertn) is mostly used for liver disease treatment. Hairy root cultures derived from S. marianum are able to produce silymarin. Elicitation of hairy root cultures is an important strategy for improving the production of secondary metabolites. The elicitors could be changed metabolite biosynthesis pathway and are useful for study of cell signaling pathway. In this study after preparation of S. marianum hairy root cultures، the effects of various levels of Fusarium oxysprum and Phytophtora meloni extract (0، 10 and 20 mg 50 ml-1 culture) in 4 different exposure times (0، 24، 48 and 72 h) have been investigated on flavonolignans production. The flavonolignans were analyzed by High Performance Liquid Chromatography method. Our results showed that hairy root cultures of S. marianum were consisted of a large number of flavonolignans including silychristin، silydianin، silybin، isosilybin and taxifolin. The highest production of silymarin (0. 32 mg g-1 DW) was observed in F. oxysprum elicited root cultures (10 mg/50 ml culture) after 72h (2. 28- fold that of the control). In Ph. meloni treated root cultures (20 mg/50 ml culture)، the maximum silymarin production (0. 13 mg g-1 DW) was obtained after 72 h (1. 9- fold that of the control). In this experiment it has been concluded that hairy root cultures of S. marianum are susceptible to elicitation by fungal elicitors and is useful for efficient large-scale production of silymarin by hairy root cultures of S. marianum.
