BRIEF DESCRIPTION OF THE BACKGROUND ART

Skin is made up of two primary layers that differ in function, thickness, and strength. From outside to inside, they are the epidermis and its sublayers, and the dermis, after which is found subcutaneous tissue, or the hypodermis.

The epidermis, the outermost layer of skin, is thin but complex. Melanin, which is responsible for skin pigmentation, is found throughout the epidermis. The epidermis also keratinizes to produce nails, hair, sweat, and to regenerate.

Keratinization, the maturation and migration of skin cells, begins in the innermost layer of the epidermis, the stratum germinativum [see item E in FIG. 1]. These cells, called keratinocytes, accumulate and move outward toward the next epidermis layer, the stratum spinosum [see item D in FIG. 1], where they become dense. The next layer, known as the stratum granulosum [see item C in FIG. 1] layer, contains 1 to 3 rows of flattened cells whose cytoplasm contain small granules. The granules contain proteins being transformed into the waterproofing protein keratin. It is in this layer that one finds glycolipids and a thickening of the membrane. A protein called filigrin is made in this layer and is put in the granules. In this layer, cells lose their nuclei. In the cytoplasm, there are keratohyalin granules as well as membrane-coating granules which expel their lipid contents into the intercellular spaces. Lipids assist in the formation of water barriers among the cells of the skin, which, in turn, help to ensure body moisturization. At this point, the cell also becomes flattened, or horny, and the nucleus disappears; what remains is keratin. In the next layer, the stratum lucidum [see item B in FIG. 1], the cell is prepared to move into its final sublayer with the addition of melanin granules. Then, sudden changes in enzyme function cause cell death. The products of this ongoing process form the stratum corneum [see item A in FIG. 1], which is the outermost epidural layer consisting of neatly packed dead horny cells.

Keratinization disorders in the stratum granulosum layer in the epidermis can often lead to clinically significant skin manifestations. One common disorder includes thinning of the stratum granulosum layer due to malfunctioning of the keratinization process leading to reduction in the moisture barrier properties of the stratum granulosum layer. In addition, for example, over activated keratinocytes actively producing and secreting pro-angiogenic factors in the form of growth factors or cytokines can result in increased blood vessel formation in the papillary dermis which may sometime extend into the epidermis. Epidermal microvascular proliferation ultimately leads to epidermal keratinocyte hyperproliferation, thickening of the epidermis with parakeratosis of the stratum corneum and inflammatory infiltrate around the blood vessels in the papillary dermis [see FIG. 1]. The microvascular changes are also characterized by increased tortuosity of dermal capillary loops which precedes the development of epidermal hyperplasia. Mitotic activity in the basal and suprabasal cells are greatly increased [Dr. George Jacob, Seminar on Psoriasis, Dubai, Jan 2001]. Cellular invasion takes place, particularly in the suprapapillary region to form the Munro ‘micro abscess’ which are extruded in the horny layer or they may collect in disintegrated malphigian cells, the cytoplasm of which had been lysed to form the multilocular or Stratum Granulosum of Kogoj [see FIG. 2]. Stratum Granulosums of Kagoj are multilocular pustules in the upper stratum malpighii within a sponge-like network made up of flattened keratinocytes [M. S. Stone and T. L. Ray, DermPath Tutor, Department of Dermatology, Iowa College of Medicine, September 1995]. They are seen in psoriasis, Reiter's disease, geographic tongue and rarely in candidiasis. Histological studies, including immunocytochemistry, routine histology and electron microscopy have clearly established that alterations in the blood vessel formation of the skin discussed above are a prominent feature of psoriasis and there is a marked increase in cutaneous blood active edge of the psoriatic plaque [Braverman I M, Yen A. Ultrastructure of the capillary loops in the dermal papillae of psoriasis. J Invest Dermatol 1977: 68: 53-60].

Numerous therapies in the field of allopathy medicine [Treatment of psoriasis-Part 1-Topical Therapy and Phototherapy, Mark Lebwohl, M D, et al, American Academy of Dermatology-October 2001-Vol 45-November-4; Treatment of psoriasis-part 2-systemic Therapies, Mark Lebwohl, M D, et al-American Academy of Dermatology-November 2001-Vol 45-Number 5; The immunological basis for the treatment of psoriasis with new biological agents. James. G. krueger, M.D, American Academy of Dermatology-June 2002-Vol 46, Number 1, Pages 1-26; New psoriasis Treatments based upon a deeper understanding of the pathogenesis of psoriasis vulgaris and psoriatic arthritis-Jeffrey. P. callen et al American Academy of dermatology, August 2003-Vol 49, Number 5, Pages 351-356] have been researched and developed to reduce the Stratum Granulosum disorder especially related to Psoriasis. However, most of these therapies provide only temporary symptomatic relief and are either unsatisfactory or very expensive [National Psoriasis Conference, Boston Plaza Hotel, Aug. 5-8, 2005, Boston, Mass., USA.] and are associated with either short term or long term undesired side effect profiles.

Herbal formulations are well known to minimize risk of undesired side effect profiles and hence provide a viable alternative therapy to manage this disease condition. Research efforts to develop Herbal formulations to treat this disease condition have been on the rise [Chopra, R. N., Nayar, S. C., and Chopra I. C., Glossary of Indian Medicinal Plants, C.S.I.R., P.259, 1956; Murugesa Mudaliar, K. S., Gunapadam (Material Medica) Vegetable Section, Govt. of TamilNadu, P. 527 (1969); Venkatarajan, S., Sarabendra Vaithiya Muraigal, P. 160, 161 & 167 (1965); Wealth of India, Raw Materials, Vol. X, P. 588-590, CSIR., New Delhi (1976); Yugimuni Vaidya Chintamani (800) Stanza 494-518, B.

B., Geetha, A., and Ramiah, N., Effect of Nimbidin in Psoriasis, Indian Medical Journal, October 1978] and there is a continuing need to develop Herbal formulations to treat this disease condition with minimal or no side effects. This patent provides Herbal formulations from Wrightia Tinctoria and Cocos Nucifera developed by a dermatologist and clinically proven to be safe and efficacious to reduce Stratum Granulosum disorder.

EXAMPLE

Twenty patients were enrolled in a clinical study and were divided into two groups of 10 patients each. Group I was treated with the Herbal formulation (see Table 1 for details) once daily and Group II was treated with Allopathy control formulation (see Table 2 for details) once daily. All patients recruited were screened to be suffering from Stratum Granulosum problems (Psoriasis patients).

Randomization was done as per standard statistical methods to minimize bias in the study. Patients were enrolled into the study on a first come first served basis and assigned a subject number sequentially. The assignment of each patient to the treatment group was determined by the randomization list provided by the statistician.

Each patient enrolled in the study voluntarily and received the treatment for 8 weeks. Skin Biopsies at the treatment site was taken from all patients at the beginning (T0) and end of the study (T8w) for Histopathological evaluation. In addition, at the beginning (T0), end of treatment (T8w) Haemogram analysis, Liver Function Testing and Renal Function Testing were done to document the safety profile of the treatments administered.

Histopathology of the skin biopsy was done by an expert pathologist and the Stratum Granulosum parameter was measured at visits T₀ and T_8W. The results of the Stratum Granulosum measurements were scored as follows: (3)=representing Absence of Granular Layer; (2)=Thinning of Granular Layer; and (1)=representing Normal Thickness Granular Layer. Stratum Granulosum parameter represents the thickness and integrity of the stratum granulosum layer. More active the disease thinner is the stratum granulosum layer and lower is the lipid content.

FIG. 3 presents photos of micrographs observed before and after treatment with patients treated for 8 weeks with the Herbal formulation presented in this invention. It is clear from the photographs that the treatment with The Herbal formulation is very effective in increasing the integrity and thickness of the Stratum Granulosum layer as compared to prior to the start of treatment.

Results of the statistical analysis of the Stratum Granulosum measurement data for the 2 different groups of treatment are presented below in

To examine the treatment effects, t-test was done with data between the two groups at the beginning and end of treatment. No statistical significance was observed (p>0.05) for treatment effects on the Stratum Granulosum measurements at the beginning (p=0.388) and the end of treatment (no difference in values between treatments).

To examine the time effects within each group, paired t-test was done with data at the beginning and end of treatment within each group. With the Herbal Group, there was a statistically significant time effect (p-values equal to 0.015) on the Stratum Granulosum measurements and it was found that the Stratum Granulosum values decreased with time suggesting positive response to Herbal treatment with time.

However, with the Allopathy Control (Group II), it was found that there was no statistically significant time effect for the Allopathy control formulation (p-value equal to 0.081).

The statistical data analysis clearly indicates that the Herbal treatment for regression of Stratum Granulosum in keratinization disorders is very Effective and is superior to the allopathy control formulation.

The safety of the use of the Herbal Formulation of the present invention for regression of Stratum Granulosum in keratinization disorders over the treatment period was evaluated by measuring Vital signs, Haemogram measurements, Liver function Test (LFT) measurements, and Renal Function Test (RFT) measurements and analyzing the data as a function of time. Vital signs were measured 6 times during treatment (T0, T1w, T2w, T4w, T6w, and T8w); Haemogram, LFT and RFT measurements were made only at the beginning and end of the treatment (T0, T8w).

Results of the Statistical analysis of the Vital Sign measurements (Systolic and Diastolic BP, pulse rate and respiratory measurements) are presented in Table 4. BP was measured using a manual mercury sphygmomometer and the unit of measurement is mm of Hg. Pulse rate was measured (beats per minute) in the radial artery by palpating the artery with the middle, index and ring finger. Respiratory rate was measured by watching the expansion of abdomen with each respiration and counting them for one minute.
