Function Olfactory receptors are present in the superior nasal conchae and nasal septum. Anatomy The unmyelinated axons pass through the cribiform plate to synapse in the olfactory bulb. The olfactory bulb is located beneath the surface of the frontal lobe. Axons leave the olfactory bulb as the olfactory tract and connect to prepyriform cortex. The term parosmia describes a qualitative change in smell while total loss of Symptoms smell is known as anosmia. Disorders of smell usually develop slowly and insidiously (except in traumatic brain injury) and are commonly associated with impaired taste. Olfactory hallucinations may accompany seizures or psychosis. Altered smell is difficult to quantitate on examination. Each nostril is tested Signs separately for the patient’s ability to smell coffee, peppermint oil, oil of cloves and/or camphorated oil. Ammonia provokes a painful sensation and can be used to diagnose fictitious anosmia. In acute trauma, nasal bleeding and swelling may impede examina- tion.
The surface of the skin appears phosphorescent purchase 600mg trileptal otc, and in the dermis, one can observe many molecules of ﬂuorescent collagen extending from the superﬁcial dermis till the lipodermic layer. It is interesting to note that the molecules enter precise zones of the skin using the channels—‘‘the watery electropores. Figures 2 and 3 show the large molecule of bovine collagen to be unaltered, as the placebo test shows the validity of the experimentation. This test shows the effect of this methodology in introducing substances such as bovine collagen or elastin into the dermis and lipodermal layer using dermoelectric pora- tion. In another part of the study, the test shows that using only microdermabrasion or only dermoelectroporation does not produce this result, conﬁrming the importance of integrated treatment. Biologically active drugs and macromolecules such as peptide drugs, proteins, oligo- nucleotides, and glycosaminoglicans are characterized by a short biological half-life and scarce bioavailability; such characteristics make it difﬁcult to employ therapeutic strategies ROLE OF DERMOELECTROPORATION & 295 Figure 1 Section of skin of an experimental rat after treatment by Transderm1 (Â150). The skin surface appears uniformly covered by ﬂuorescent. Numerous molecules of ﬂuorescent collagen are observable from the outermost part to the inner part of the dermis. Figure 2 Microscopic extension of many molecules of bovine collagen type 1 ﬂuorescent (0. The surface of the skin appears uniform and ﬂuorescent but, in the dermis, there is no observation of any ﬂuorescent molecules. In this experimental study, the authors have used a new type of dermoelectroporation, which involves the application of pulsed electric ﬁelds with 1 Transderm. Moreover, they have analyzed the transdermal delivery of biologically active molecules in vivo. The advantage of using pulsed electric ﬁelds as opposed to continuous ones is that there is a signiﬁcant reduction in the degradation of the molecules to be trans- ported as a result of the electrolytic phenomena.
