In this study, we attempted to identify the polyphenolic compounds of two species of the genus Parietaria (fam. Urticaceae), namely Parietaria lusitanica L., harvested from Toulouse (France) and an indigenous species, Parietaria officinalis L., harvested from the forest Fantanita-Murfatlar (Constanta county, Romania). The work method used for the qualitative and quantitative differentiation of the polyphenolic compounds in the vegetal products of these species was high-performance liquid chromatography (HPLC). The...

Age, obesity, sex and previous injuries are considered to be significant risk factors for osteoarthritis. Mud is a therapeutic agent used since ancient times to treat osteoarthritis. Although extensively used, the mechanisms by which balneal therapy acts are poorly studied, sometimes we can even say that they are "full of surprises". The complexity of its biochemical composition, the rich microbial flora, the inter-relationships between its components, slow down the detection of the physiological and therapeutic e...

The highest quantity of cyanogen compounds in the environment results mainly from human activities (ore extraction, cleaning and hardening metals, galvanization etc). People with metabolic disorders in cyanide conversion to thiocyanide show a higher risk of intoxication with cyanogen substances. Some deficient diets may increase the risk to cyanide exposure. Thiocyanide, the main metabolite of cyanide, cause endemic goiter in humans and animals. In the studies, orally administrated cyanide and thiocyanide to rats,...

It is known that complex polysaccharides (polyuronides) are natural macromolecular compounds located in all the plant organs in special histological formations (cells and canals), as well as in the external seminal tegument. In contact with water, they form colloidal solutions or gels. Under the action of the intestinal flora they are split and form a protective film for mucous membranes as well as create a pH unfavorable for the development of the pathogenic microbial flora involved in the degradation of the inte...

Aging is one of the most amazing biological processes. There are more than 300 theories that try to explain the phenomenon of aging from biological but also social perspective. The most involved in this process are those that secrete hormones from the ovary (estradiol), from the testis (testosterone), from the adrenal (DHEA, cortisol) and from the pituitary gland (GH - growth hormone). This paper focuses on the study of endocrine changes of pituitary-adrenal axis as an indicator of biological aging under the influ...

It is well known that the pathogenic mechanism of algic posttraumatic syndrome is still incompletely understood. Although multiple attempts have been made to reduce chronic regional pain syndrome to a single pathophysiologic mechanism (e.g., sympatho-afferent coupling), it has become increasingly accepted that there are multiple mechanisms involved. Only in the past few years, has it been recognized that chronic regional pain syndrome is not simply a sympathetically mediated peripheral pain condition but rather is...
