Disclosed herein is a photochemical preparation method of an autologous plasma inactivated vaccine for the treatment of acquired immune deficiency syndrome (AIDS), including the following steps: drawing autologous blood from an AIDS patient to form blood to be treated; separating the blood to obtain plasma to be treated; adding a photosensitizer into the plasma to be treated to form plasma to be inactivated; and subjecting the plasma to be inactivated to photochemical inactivation to obtain the autologous plasma inactivated vaccine.

The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

The present invention relates to a device and a method for treatment or disinfection of a volume comprising bacteria in the vicinity of cells, such as a laser device and the use of the laser device for the treatment of wounds. In particular, it relates to the treatment of chronic wounds.

Methods and apparatus provide therapeutic electromagnetic radiation (EMR) for inactivating infectious agents in, on or around a catheter residing in a patient's body cavity and/or for enhancing healthy cell growth. Transmitting non-ultraviolet therapeutic EMR substantially axially along an optical element in a lumen of the catheter body and/or the catheter body. Through delivery of the therapeutic EMR to particular infected areas and/or areas requiring tissue healing. The inactivation of the major sources of infection in, on, and around catheters and/or enhance healthy cell growth around catheters is accomplished by utilizing controlled relative intensity and/or treatment region specific dosing of the therapeutic EMR emitted radially from the optical element. Specific embodiments of urinary catheters and peritoneal dialysis catheters are also disclosed.

An object of the present invention is to provide a sterilization method for a medical rubber product in which non-eluting characteristics are maintained even after sterilization with gamma ray and with which less troubles occur in a medical product manufacturing process. The medical rubber product according to the present invention is a medical rubber product formed from an elastic material and sterilized by being irradiated with gamma ray or electron ray (beta ray), wherein, when measurement is performed on a surface portion of the elastic material through ATR by using an FT-IR, if an area of an infrared absorption peak at around a wave number of 1650 cm.sup.?1 in an infrared absorption spectrum obtained through the measurement is defined as As and an area of an infrared absorption peak at around a wave number of 1470 cm.sup.?1 in the infrared absorption spectrum is defined as Bs, Ss=(As/Bs)?100?6 is satisfied.

A solution for controlling mildew in a cultivated area is described. The solution can include a set of ultraviolet sources that are configured to emit ultraviolet and/or blue-ultraviolet radiation to harm mildew present on a plant or ground surface. A set of sensors can be utilized to acquire plant data for at least one plant surface of a plant, which can be processed to determine a presence of mildew on the at least one plant surface. Additional features can be included to further affect the growth environment for the plant. A feedback process can be implemented to improve one or more aspects of the growth environment.

Portable multifunctional device designed for sanitizing of inner and outer surfaces of shoes, sanitizing of air, water, household items and surfaces, treatment of skin and wound infection, nails fungus, cosmetic use, and detection of counterfeit currency. The device is able to perform all the above sanitizing, therapeutic and cosmetic functions that would otherwise be carried out by various different devices. The enhance functionality has been accomplished without alteration of any parts of the device. Apparatus utilizes light radiation in three diapasons: 100-280, 405-495, and 700-1064 nm and provides distant sanitizing. Apparatus comprises at least one module with a dual DC-AC power supply. Each module has a germicidal unit, retractable flexible shaft, shade, and housing. The flexible shaft allows positioning the germicidal units under different angle for uniform distant illumination.
