he external skin layer, called epidermis, is a dynamic system of continuously proliferating and differentiating activity. It mainly consists of keratinocytes, melanocytes and immunocompetent cells (Langerhans cells). Structure and metabolism of the epidermis have two essential functions: to protect the skin from external influences and to maintain the hydration and the osmotic balance of the in...

Two oleogum resin essential oils (from two different seasons: fall and summer), of Boswellia spp. (collected from Somalia), were obtained by hydrodistillation and analyzed by GC-MS. Out of 147 peaks, components were identified among the two essential oils accounting for 100%, and 99.7% of the oils, respectively. The two essential oils were dominated by the 1-methoxy alkane [octyl methyl ether (...

Mutagenic properties of terpenes (both synthesis and plant derived) have been tested, up to now, as a single molecule. A terpenes containing hydro-alcoholic solution deriving from frankincense and myrrh resins and hyssop essential oil was assayed for mutagenicity by means of ames test. Extraction technique conducted with electromagnetic fields at room temperature enabled to obtain a solution of...

BACKGROUND On St. Kitts, a high number of cats are found to be infected with Trichuris. Necropsies have shown pathologic changes related to the infections. In order to determine if these changes were related to a particular Trichuris species, a review of the original identifications of Trichuris campanula and Trichuris serrata was conducted. FINDINGS Based on the review of published descripti...

The yield of hydrodistillation of a botanically certified Oleogum Resin of Boswellia sacra essential oil (5.5%); and its chemical constituents were determined. The GC/MS technique was used for the analysis of the oil. Several oil components were identified based upon comparison of their mass spectral data with those of reference compounds published in literature or stored in a computer library....

BACKGROUND Boswellia serrata and Melissa officinalis is traditionally used for its memory enhancing effects. OBJECTIVES In this study, we evaluated the protective effects of combined form of these extracts on memory improvement of scopolamine treated rats by the Morris water maze method. MATERIALS AND METHODS Two groups (group 1 and 2) of animals were pretreated with combined extracts of B....

Boswellic acids have long been considered the main bioactive components of frankincense, and many studies in vitro and in animals as well as several clinical studies have confirmed their various bioactivities. In particular, a large number of mechanistic studies have confirmed their anti-inflammatory and antitumor activities. However, not every boswellic acid exhibits a satisfactory pharmacolog...
