| Abstract|| |
It has been reported that the Japanese have higher rate of life expectancy and that Japan is rapidly becoming a super aging society. Almost 5 per cent of the aged, who develop diseases such as cerebrovascular related disorders, mental problems, fractures, cancer and infections also end up suffering from bedsores. It has been found that patients often opt for treatment, when the bedsores become very severe and adding more complications in their treatment. It may be presumed that prevention and early detection are vital for the treatment of bed sores. In our present study, we have tested herbal formulations having Aloe vera gel powder for its efficacy and activity on bed sores. Aloe vera gel powder with high molecular weight (AHM) was prepared from the gel part, by washing with running water using the patented freeze-drying under micro wave and far infra red irradiations in which barbaloin content was less than 10 ppm in powder form. The treatment was given by applying the macromolecule aloe ointment for bedsores from I degree to Il degree ulcer patients. The results have shown that AHM in the ointment form indicated a high possibility to cure bedsores. Being very difficult to cure, due to the patient's peculiar conditions such as old age, inability of the patient to turn by himself/herself and also due to complications caused by other symptoms. We were able to confirm the effectiveness of the macromolecule aloe ointment in four cases of bedsores with two cases of positive control, using the Design Score and by checking the side effects. In this study, our report is based on the preclinical trials for bedsores by the external use of the macromolecule aloe ointment.

| Introduction|| |
The topical application of Aloe vera gel is perhaps effective in the treatment of psoriasis , , genital herpes , and decubitus , . However, there is confusion about Aloe preparations which were applied in clinical studies  . Chemical and physical evidences are needed for healing effects of Aloe preparations. Utilising the change in mode of preparation method and material as a natural product is required. Recently, upon application of Aloe vera gel in genuine form to preclinical studies, we developed a new technology for preparing Aloe vera gel powder with high molecular weight. This was done by using a patented hybrid-dry system, which has been applied to make dry substance without tissue and cellular damages in the field of natural sources rich in water content, such as fish, seaweeds and Aloe vera gel etc. Topical application of some Aloe vera gel preparations causes contact dermatitis in rare cases and aloin could be an irritant to the skin  . The International Aloe Science Council (IASC) has authorized that the content of 'loin in Aloe vera gel preparation is less than 50 ppm. Topical application of Aloe vera is not an effective preservative for radiation-induced injuries, and whether it promotes wound healing is unclear  . There are few reports on the effectiveness of Aloe vera gel therapies on chronic wounds  . A recent study of Aloe vera gel for burn healing concluded that the group that was being given Aloe vera recorded a healing time that was 8.79 days shorter than those in the control group (p=0.006)  . Present case reports of AHM in the ointment preparation were carried out to determine the efficacy of bedsores after preliminary humidity test of the aloe ointment.
| Material and Methods|| |
Four patients identified as I degree, n degree or in degree with ulcers and who had been hospitalized at Taihei Hospital in Japan.
Eight months during September, 2005 and October, 2008.
Consent of Patient
We obtained the consent of the patients for this treatment by document or word of mouth by free will after explaining the contents to them before proceeding with the treatment. All procedures used in the protocol were in accordance with the Helsinki Declaration. In addition, we obtained the consent from the patient's family; when the patient was unable to judge through Hospital Committee equivalent to the Institutional Review Board.
Aloe vera L. plant, syn. A.barbadensis Miller, cultivated in Okinawa, Japan, was compared and determined to be Aloe vera L. (Herbarium number 54-3 in Medicinal garden, Fukuyama University by Prof A.Yagi). The macromolecule aloe ointment is a mixture of the hydrophilic ointment and AHM at 0.1% by weight. AHM were prepared from the gel part washed with running water by the patented freeze-drying under microwave and far infra red irradiations in which barbaloin content was less than 10 ppm in powder form. AHM MW: 1,119,500 D by HPLC analysis: colony formulation unit, less than 300/g, Na+ approx. 430 mg/ 100g, Ca 2+ approx. 2100 mg/ 100g, Chemical shifts of AHM on 1 H- and 13 C-NMR were determined in D2O with a JOEL JNM alpha-400 at 400 and 100 MHz for proton and carbon, respectively. The infra red spectra were obtained with a FTIR-8600PC, Shirnadzu, Japan.
1 H NMR ( ppm, 10 mg/ml in D2O at 34.3°C: TMS as an internal standard): 2.12 (s, CH 3 COO), 2.58 (br. s, - C(OH)-CH 2 000H, citric acid), 2.74, 2.78 (d.-CH 2CH(OH)COOH, malic acid), 3.4-4.0 polysaccharides,- CH(OH)CH(OH)-), 3.97(m,-CH 2 CH(OH)000H,matic acid), 4.18 (m,-CH 2 -CH(OH)COOH, malic acid), 5.19, 5.20 (br. s. anomeric proton of the non-reducing carbon atom), assigned by comparison with 1 H NMR data base of IASC.
13 C NMR (ppm, 10 mg/mt in D2O at 34.3 °C: TMS as an internal standard): 62.1(C6), 70.9, 75.4, 77.0, 77.1, 97.1 (Cl), 175.9 (CH 3 COO). IR (KBr) vmax: 3381(OH), 2922 (COON,-NH-), 1735 (CH 3 000), 1597(-NHCO-), 1245 (-CHOH), 1033(-CHOH). Carbohydrate and protein content in AHM was determined according to phenolsulphuric acid  and Lowry method  , to 90% and 7%, respectively. A glycoprotein fraction, verectin, composed of carbohydrate and protein in a ratio of 10.7% and 82.0%, respectively with MW of 29KD  , was contained in a ratio of 20% in AHM by immunochemical assay  . Humidity test of cuticle was carried out by using ASA-M2/SS, ASAHI BIOMED, Yokohama, Japan. The physical conversion in less than 2 hours was applied with the nutritional control side by side.
Pre-treatment: In case the skin ulcer therapeutic drug had been used on a patient, then an isotonic sodium chloride solution was applied for washing it out and a gauze dressing was put for 7 days. As a positive control, gentamicin ointment was applied.
After the skin ulcer therapeutic drug had been washed out, AHM ointment was applied to the diseased part once or twice a day after washing it with an isotonic sodium chloride solution.
Through the trial term, all medications, such as steroids, blood stream accelerants and others which influence efficacy of the aloe ointment were completely avoided.
According to Design Score, all the diseased part was periodically evaluated every month.
Monthly medical examination through interview and an ocular check up on the side effects was done. In case, side effects were found, the tracing survey was conducted till they disappeared. Simultaneously, the analysis of these side effects on sort, degree, day of appearance, progress, treatment, day of disappearance and causality with the macromolecule aloe ointment was also conducted.

The ulcer square
It was done by measuring the dimension covering longer diameter (cm) x shorter diameter (cm). In each item, point 0 indicated cured or unrecognized, and if the point is more which indicated the condition has worsened.
For e.g. Case 1: (126.96.36.199.1.0.1.) = (D=1. E=2. S=3. 1=2. G=1. N=O. P=1) = point 10
Case 2: (188.8.131.52.0.0.0.) = point 3: Seven points were reduced.
At the time of Case 2, the diseased part was Extremely Improved than at the time of Case 1. The judgment was done according to 1) above. The treatment was recorded at the beginning using the Design Score. Thereafter, every check was recorded, and compared with that of the starting treatment, and judged.
Availability judgment of the macromolecule aloe ointment:
The availability was judged according to the reduced points in Design Score and the occurrence (or none) of side effects.

| Results|| |
Average value of humidity (admittance, micro S, n=6) at each measurement point of stratum corneum epidermidis (cuticle) on arm after 15, 60 and 90 min are shown in [Table 1]. Also, as shown in [Table 1], the aloe ointment exhibited a tendency to conserve humidity on cuticle during 90 min at least.
In the preliminary test, the patient responders, concentration of dose and test time to the powder solution after patch test and informed consent were determined. Negative reaction of the patients to patch test was obtained. Case reports of four patients comparing with that of two positive controls, showed improvement by use of aloe ointment in DESIGN SCORE without any side effects.
| Discussion|| |
In an earlier in-vitro experiment, verectin, a glycoprotein fraction isolated from Aloe vera gel, showed a proliferation-promoting activity on human dermal (NB1RGB) and hamster cells  . Verectin also inhibited the generation of 02- by xanthine-xanthine oxidase and cyclooxygenase (Cox)-2 and thromboxane (Tx) A 2 synthase. Inhibition of Cox-2 and Tx A 2 synthase level is closely linked to prostaglandins levels in tissue injury, and verectin fraction plays an important rote in the anti-inflammatory activity of Aloe vera leaf get  . Furthermore, ELIS4 using polyclonal rabbit antiverectin anti-serum indicated the localization and identification of verectin in Aloe vera leaf gel and commercial Aloe vera gel products  ,Verectin content in AHMwas shown at 20% concentration.
As a preliminary study, we performed humidity test of the aloe ointment to patient responders. [Table 1] shows possible conservation of humidity on cuticle by AHM in the ointment preparation. AHM having acetyl groups in macromolecular mannan , may be easily dispersed to form the hydrophilic ointment as 0.1% by weight and used as the material for this bedsore clinical trials. The ointment contains macromolecular polysaccharides and glycoprotein as the crucial ingredients of fresh Aloe vera gel. The results of this trial showed that AHM in the ointment preparation has a high possibility to cure bedsores. It has often been stated that bedsores are one of the most difficult problems to cure because of the patient's peculiar conditions such as old age, inability to turn by himself I herself and complications caused by other symptoms. The success of aloe vera gel in the treatment of bedsores may be attributed to its wound-healing and anti-inflammatory activities, with no side effects, has high competence of epithelialisation followed by tissue and texture restoration. Further, it has potential for quick remedy, which will greatly help the aged patient's QOL - Quality of Life and have high efficacy compared to gentamicin ointment.
The results showed that AHM contains rich and good macromolecular polysaccharides with acetyl groups and glycoprotein fraction, verectin, to cure bedsores. The combined action of these ingredients which showed anti-oxidation and prostaglandin 2-inhibition in vitro may be effective in curing bedsores. AHM ointment was shown to penetrate tissue, relieve pain, reduce inflammation and increase blood supply to the damaged area. Our hypothesis is that macromolecular polysaccharides as an adjuvant, can physically absorb and hold the exudates through the osmotic pressure differences, so that the desirable moisture condition to cure wounds is maintained. It also provides a rich nutrition, playing a part in the regeneration of tissue, texture and epidermis that need to be restored. In addition glycoprotein fraction such as verectin has attributed for its anti-inflammatory activity and wound-healing property , . The remarkable point of AHM preserved by new technology is that it do not lose the high molecular structure with acetyl groups and glycoprotein, and verectin moiety for the first time. Therapeutic trials not only for bedsores but for general wound-healing using AHM ointment are fully expected.
