Method and apparatus for determining the hematocrit of a blood sample utilizing the intrinsic pigmentation of hemoglobin contained within the red blood cells

A method for determining the hematocrit of a blood sample is provided that includes the steps of: 1) depositing the sample into an analysis chamber operable to quiescently hold the sample for analysis, the chamber defined by the interior surfaces of first and second panels and a height extending there between, wherein both panels are transparent, and the height is such that at least some of the red blood cells within the sample contact both interior surfaces of the panels and one or more lacunae within the quiescent sample extend between the interior surfaces; 2) imaging at least a portion of the quiescent sample, which sample portion contains the red blood cells and one or more lacunae to determine an optical density of the imaged portion of the sample on a per image unit basis; 3) selecting and averaging the optical density values of the image units aligned with the red blood cells contacting the interior surfaces, and assigning an upper boundary value of 100% to the average optical density value of those image units; 4) selecting the optical density values of the image units aligned with the one or more lacunae, and assigning a lower boundary value of 0% to the optical density values of those image units; and 5) determining the hematocrit of the sample by assigning relative values to the optical density value of each image of the imaged sample portion as a function of the upper and lower boundary values, and averaging the relative values.

Camellia oil preparation method for cosmetics

The invention relates to a preparation method of cosmetics camellia oil. High-quality camellia seeds are selected to be used as the raw material; the camellia seeds are roasted under the negative pressure and at the lower temperature, and are husked after natural cooling and are squeezed at the room temperature to obtain high-quality crude oil with low acid value and pale yellow color; impurities are removed through filtration under the heating condition, alkali refining and ethanolic extracting two-stage process is utilized for acid stripping and de-coating; then the mixture composed of active carbon and floridin is used as de-coloring agent for de-pigmentation; peroxide and unclean flavor are removed through deodorization; then the drying winterization is acted; finally, the cosmetics camellia oil is obtained, wherein, the acid value is less than 0.1 mgKOH / g, the peroxide value is less than 0.5 mmol / kg, the appearance is colourless approximately as well as clear and translucent, and no unclean flavor exists. The cosmetics camellia oil reaches or exceeds the requirement of the national standard GB11765-2003 on first level expressed tea-seed oil, and can be directly used for manufacturing the cosmetic such as skin care oil for babies; in addition, an edible camellia oil fabrication plant can be improved for production, thereby lowering the investment cost greatly.

Method and Apparatus to Compensate for Melanin and Hemoglobin Variation in Determination of a Measure of a Glycation End-Product or Disease State Using Tissue Fluorescence

A method of determining a measure of a tissue state (e.g., glycation end-product or disease state) in an individual is disclosed. A portion of the skin of the individual is illuminated with excitation light, then light emitted by the tissue due to fluorescence of a chemical with the tissue responsive to the excitation light is detected. The detected light can be combined with a model relating fluorescence with a measure of tissue state to determine a tissue state. The invention can illuminate the skin and detect responsive light over a time that spans a plurality of cardiac cycles of the individual, which can, as an example, help mitigate the effects of time-varying signals such as those due to hemoglobin. The invention can also determine the amount of light to be directed to the skin, for example by controlling the time that a light source is energized. The amount of illumination light can be determined from a skin reflectance characteristic such as pigmentation or melanin in the skin. Controlling the amount of light directed to the tissue can reduce the dynamic range required of a corresponding optical system, for example by allowing a single system to accurately measure individuals with very light skin and individuals with very dark skin.

Chinese medicinal preparation for treating facial chloasma and preparation method thereof

The invention relates to a Chinese medicinal preparation for treating facial chloasma, which is the medicinal preparation prepared from 77 raw material medicaments such as peach seed, safflower, danshen root, red paeony root and hawthorn fruit. The medicinal preparation is powder, tablets, pills, capsules, electuary or oral liquid. A preparation method of the Chinese medicinal preparation comprises the following steps of: (1) sieving and crushing the raw material medicaments; (2) sieving, and taking screening; (3) disinfecting and sterilizing to obtain medicinal raw powder; and (4) preparing the medicinal raw powder into tablets, granules, pills or capsules. The preparation method also can comprise the following steps of: (1) preparing the raw material medicaments into medicinal water extracting solution; (2) preparing the medicinal water extracting solution into the oral liquid; (3) drying, crushing and sieving the medicinal water extracting solution, taking screening, disinfecting and sterilizing to obtain medicinal extracting powder; and (4) preparing the medicinal extracting powder into tablets, granules, electuary or capsules. The Chinese medicinal preparation has a formula based on Chinese medicinal theory, and makes five internal organs healthy, and Yin and Yang balanced. The Chinese medicinal preparation mainly treats facial chloasma, freckles and facial pigmentation, treats hair loss caused by vitality stagnation and blood stasis, and has good curative effect on irregular cycles and infertility. The Chinese medicinal preparation is prepared from pure Chinese medicaments and has the advantages of diversiform formulations, convenient use, safety, reliability, no toxic or side effects, and suitability for long term usage.
