The present invention relates to a method for detecting substances specifically inhibiting a type III secretion mechanism and functions of the type III secretory proteins, within short time and large amounts thereof, without depending upon animal infectious experiments. Namely it relates to the method for detection of a type III secretory mechanism inhibitor comprising mixing a bacterium having the type III secretory mechanism and an erythrocyte suspension, adding the type III secretory mechanism inhibitor thereto, and detecting changes in the thus formed hemolytic activity. The method for detecting substances can be treated large amount of samples within short time by exhibiting the substances inhibiting the type III secretion mechanism or the functions of the type III secretory proteins as numerical index of the hemolytic activity of erythrocytes. Consequently, the present invention is useful for development of drugs.

Methods and kits for sampling mucous from within a sinus to determine if a single sample includes one or more bacterial types indicating bacterial sinusitis.

Organic compounds showing the ability to inhibit effector toxin secretion or translocation mediated by bacterial type III secretion systems are disclosed. The disclosed type III secretion system inhibitor compounds are useful for combating infections by Gram-negative bacteria such as Salmonella spp., Shigella flexneri, Pseudomonas spp., Yersinia spp., enteropathogenic and enteroinvasive Escherichia coli, and Chlamydia spp. having such type III secretion systems.

The invention provides a coenzyme Q10 fermentation process and a control strategy. Rhodobacter sphaeroides fermentation is adopted to produce coenzyme Q10, a specific operation method of coenzyme Q10 fermentation is provided, a process regulation and control standard is created, through bacterial type change in observation of the fermentation process, the bacterial type transition period is taken as a basis for judging time and amplitude for process parameter adjustment, the fermentation level of the coenzyme Q10 is greatly improved, the production level is stabilized, and the fermentation cost is reduced.

The invention relates to a simple automatic foaming and liquid discharging method for children hand sanitizer. The method comprises the steps of detecting the current emotional state of a child user when the child user is determined to exist in front of a hand sanitizer machine, recognizing whether the child user has the willingness to wash hands or not after the emotional state of the child user is determined, and when the child user is determined to need to wash hands, detecting the bacteria type, the skin type and the pollution degree of the to-be-cleaned palm part of the child user, and enabling the hand sanitizer machine to automatically output the foaming liquid which is matched with the current to-be-cleaned palm skin type of the child user and kills the bacteria type on the palm, so that the hand washing and cleaning requirements of the child user are met. Moreover, the palm skin of the child user is protected, and the damage of non-matched foaming liquid to the palm skin of the child user is avoided.

A device for sampling mucus from the sinuses to determine whether a single sample includes one or more types of bacteria indicative of bacterial sinusitis, the device including an indicator to guide the user at the angle at which the device is inserted relative to the patient .

The invention relates to a milling tool for steam turbine bacterial-type root blades, and solves the problem in the prior art that no special milling tool for processing the steam turbine bacterial-type blade root blades exists. A positioning block is vertically and fixedly connected with the middle part of one end of an upper end surface of a base plate in the width direction; a support screw passes through a first threaded hole and is in threaded connection with a pressing plate; two sides of the base plate, along the axial direction of a positioning threaded hole, are respectively fixedly connected with an ejection rod support and a support screw sequentially; a screw rod passes through the positioning threaded hole of the positioning block and is connected with a positioning thread; the lower ends of the bacterial-type root blades are clamped on the positioning block for positioning; the screw rod is rotated so as to butt against the bacterial-type root blades; each pressing plate is pressed on the upper surfaces of the bacterial-type root blades; adjusting studs are arranged in a manner of penetrating through guide grooves of the pressing plates; a nut is threadedly connected with the upper end of each adjusting stud so as to press the corresponding pressing plate tightly; and the threaded ejection rods are rotated so as to push two sides of the bacterial-type root blades tightly. The milling tool for the steam turbine bacterial-type root blades, provided by the invention, is used for clamping the steam turbine bacterial-type root blades.
