Achatina fulica’s secretion has been recently related to antibacterial, antifungal, and cicatricial properties, and it is influenced by the kind of food offered. Therefore, this study investigated the healing potential of dressing films based on mucous secretion of Achatina fulica. Thus, surgical wounds performed in black wistar rats were dressed with films based on collagen, and on mucous secr...
Algae are composed of a diverse group of various aquatic organisms. Secondary or primary metabolites from these organisms may be potential bioactive compounds of interest for use in the development of new pharmaceutical agents. In this research, four species of marine algae, Ulva lactuca, Padina pavonica, Colpomenia sinuosa and Cystoseira myrica, isolated from Persian Gulf coasts were evaluated...
background anxiety is a physiological state characterized by cognitive, somatic, emotional, and behavioral components. there is some evidence in traditional medicine for the effectiveness of lettuce (lactuca sativa) in the treatment of anxiety in humans. objectives the present study investigated the effects of a hydro-alcoholic extract of lettuce on rat behavior in the elevated plus-maze (epm) ...
Nowadays, organic fertilizers play an important role in agriculture. They are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. They provide high yield, better quality products and a shorter period of harvesting crops. In this study, the mineral elements: primary macronutrient (N, PO3- and K+), secondary macronutrient: (Ca2+, Mg...
Renewed interest in the identification of alternative sources of natural rubber to Hevea brasiliensis has focused on the Compositae family. In our search for Compositae models for rubber synthesis, we extracted latex from stems of two lettuce species: Lactuca serriola, prickly lettuce, and Lactuca sativa cv. Salinas, crisphead lettuce. Both species contained cis-1,4-polyisoprene rubber in the d...
In an earlier paper, Thompson, Whitaker, and Kosar ^ reported on some genetic relationships between certain species of the 9-chromosome and of the IT-chromosome group of the genus Lactuca. Whitaker and Thompson^ presented data on some cytological aspects of these same species. In the first of these papers mention was made of 2 of the 8-chromosome species, but no compatibility relationships were...
From the root tubers of Lactuca tuberosa, a wild edible plant species, nine phenolic compounds were isolated, including two new furofuran lignan glucosides, named lactuberin A and lactuberin B. Their structures were elucidated by spectroscopic methods, especially HRESIMS and 2D NMR techniques. This is the first time that compounds belonging to the epi series of 2,6-diaryl-3,7-dioxabicyclo[3.3.0...
ترکیبات مغذی جلبک قرمز gracilaria salicornia و سبز ulva lactuca به صورت تازه و فرآورده های آن (نمک سود ، خشک و تیمار دمایی) مورد ارزیابی قرار گرفت. به طور کلی، نتایج نشان داد که جلبک های مورد مطالعه دارای محتوای پایین چربی بوده و در عین حال منبعی غنی از خاکستر، به خصوص در g. salicornia هستند. محتوای پروتئین خام نیز بین% 9/5810/69- متغییر بود. مقادیر اسیدهای آمینه کل در g. salicornia 890 ± 53/2 ...
