According to the present invention, there are provided methods for treating age related macular degeneration in a mammal; for preventing impairment of the vision or for improving impaired vision of a mammal whose eye has drusen; for preventing formation or growth of drusen in the eye of a mammal; and for reducing the number or the size of drusen or for fading drusen without resultant areas of retinal atrophy, without resultant impairment of vision, or without a combination of the foregoing in the eye of a mammal. Beta-carotene in appropriate amounts is administered to the mammal.

Treatment of age related macular degeneration with beta-carotene

A nutritional or dietary supplement composition that strengthens and promotes retinal health through the prevention, stabilization, reversal and/or treatment of visual acuity loss by reducing the risk of developing late stage or advanced age-related macular degeneration in persons with early age-related macular degeneration. The nutritional or dietary supplement composition may likewise reduce the risk of vision loss associated with the development of cataracts. The essential ingredients of the nutritional or dietary supplement composition are vitamin C, vitamin E, beta-carotene, zinc and copper. The essential ingredients are preferably provided in a tablet form suitable for oral ingestion. Preferably the composition is taken in the form of one or two tablets taken twice daily.

Nutritional supplement to treat macular degeneration

A spectroscopic method, preferably Raman scattering, is used to rapidly determine the general health or stress status of living plants and plant products, including agricultural crops, forests, and harvested fruits and vegetables. In the preferred embodiments, carotenoid levels are used to provide an indication of oxidative deterioration. Based upon the results of the analysis, further action may or may not be taken, for example, in terms of choosing, picking, harvesting or sorting the agricultural product in accordance with the carotenoid level. Concentration levels of an analyte substance can be determined relative to an external standard, to each other, or relative to another substance in the item being analyzed. Carotenoids such as lycopene, beta-carotene, lutein, violaxanthin, neoxanthin, antheraxanthin, and zeaxanthin are determined according to the invention, through other plant components may be analyzed such as other terpenes, polyenes, chlorophyll, proteins, starches, sugars, overall nitrogen levels, flavonoids, and vitamins. The hardware associated with the invention may be field portable or mounted on a piece of equipment such as a harvester or sorter.

Optical method and apparatus for determining status of agricultural products

A pharmacologically effective or cosmetic substance for external application to treat e.g. acne, pimples, ulcers, cold sores. The substance includes an extract from plants of the grass family of plants particularly cereals, the extract including juice from green components of the plants at the unjointed stage. The extract is carried in a pharmaceutically acceptable aqueous carrier or excipient, the carrier preserving the extract against deterioration and being capable of at least partial absorption by tissues so as to carry the extract to sub-surface tissues. An anti-microbial agent is included. The substance may comprise ascorbic acid and beta-carotene, both present in the range 0.1 to 10 mg per gram of the substance. Biotin, trypsin and chlorophyll are also present.
