Membrane recovery

Signs and Symptoms Fever, anorexia, depression, and discharge from the eyes and nose. Pinpoint necrotic lesions appear on the inside of the mouth that rapidly form a cheesy plaque. Further symptoms include severe abdominal pain, thirst, difficulty breathing (dyspnea), and watery diarrhea containing blood, mucus, and mucous membranes. Recovery is prolonged and may be complicated by concurrent infections due to immunosuppression.

The use of skin permeation enhancers in combination for synergistic effects has been studied in the transdermal literature (70). Such synergistic methods can be grouped in three categories (i) combination of two physical methods, e.g., ultrasound and iontophoresis (71-75) (ii) combination of a physical method with a chemical enhancer, e.g., use of ultrasound with sodium lauryl sulfate or isopropyl myristate (76-80) and (iii) combination of two chemicals, e.g., terpenes and propylene glycol (46,81-88). Numerous studies have been published on using combination of two physical methods or use of a physical method in conjunction with a chemical enhancer. Use of a physical method, by itself or in combination with another physical method, increases application cost for delivery purposes as mentioned before. In addition, there are unexplored safety and membrane recovery issues associated with these methods. A few reports have also been published on the use of a mixture of chemical enhancers for enhancing transdermal delivery. Typically, such studies use...
