Abstract: The invention comprises a method of controlling fleas which includes continuously administering to the haircoat of a homeothermic animal an ovicidally effective amount of 2-(1-methyl-2-(4-phenoxyphenoxy)ethoxy)pyridine (pyriproxifen) from a sustained release matrix at a rate of 0.1 mcg/kg/day to 100 mcg/kg/day. The method may also include the use of additional ingredients such as insecticides, plasticizers, lubricants and antioxidants in a sustained release matrix.

Abstract: Stabilized pulverulent active agents, compositions containing them and also process for obtaining them; such stabilized active agents enable dry and stable pharmaceutical, dietary, nutritional or cosmetic compositions to be obtained, in which the properties of the said active agents are neither modified nor impaired. Such stabilized active agents are stabilized by coating with a coating composition comprising:-- at least one film-forming agent, in proportions of between 2 and 25% by weight of the final mass, selected from polyvinylpyrrolidones (povidone), polyvinyl alcohols, vinylpyrrolidone/vinyl acetate copolymer, vinylpyrrolidone/polyvinyl alcohol copolymer, cellulose derivatives such as cellulose acetate, cellulose acetate phthalate, cellulose butyrate, ethylcellulose and methylcellulose, acrylic and methacrylic polymers and copolymers and vegetable, animal or synthetic waxes, and-- at least one pore-forming agent, in proportions of between 0 and 5%, by weight preferably of between 0.

Abstract: Hydroquinone amino-acid esters having formula (I), pharmaceutical or cosmetic compositions containing them, particularly dermatological compositions having pigment-removing activity, and the pharmaceutical, cosmetic or aesthetic uses thereof. The preparation of these novel hydroquinone esters from natural amino-acid derivatives is also described.

Abstract: The present invention is a method for controlling ectoparasites. More particularly, the invention relates to a method of treatment in which the warm blooded animal is dosed with an ovicidally effective amount of a heterocyclic nitrogen compound selected from the group represented by the formula: ##STR1## wherein R.sub.1, is either one of the following groups: ##STR2## R.sub.2 and R.sub.3 are the same or different, each a hydrogen atom, a halogen atom or a methyl group; R.sub.4 is a halogen atom or a methyl group; R.sub.5 and R.sub.6 are the same or different, each a hydrogen atom, a halogen atom, a C.sub.1 -C.sub.4 haloalkyl group or a C.sub.1 -C.sub.4 haloalkoxy group; X, Y and Z are the same or different, each an oxygen atom, a sulfur atom or a methylene group, which is transmitted to the ectoparasite by the animal's blood. In a further embodiment, a compound selected from the group consisting of ivermectin, milbemycin, milbemycin oxime, moxidectin and avermectin and avermectin derivatives.

Abstract: A device enabling one or more active principles or substances to be released in a gradual and programmed manner, wherein the device can be obtained by:a) preparing a powder comprising a resin or polymer matrix in which at least one suitable plasticizer is fully absorbed by heating the plasticizer and hot spraying it onto the matrix while it is being maintained in temperature, thereby saturating the resin with plasticizer;b) cooling the powder obtained in a) to a temperature below 30.degree. C;c) cold mixing the powder obtained in b) with at least 5% of at least one carrier of active principle; thend) adding the active principle(s); ande) suitably forming the powder obtained in d) by any appropriate means, which device releases the active principle uniformly and completely.The device further includes a covering made of a polymer which is impermeable to the active principle(s) and which covers a portion of the surface of the device.

Abstract: An ultrasonic probe is adapted to be implanted in a human or animal body in contact with a wall of an organ to allow exploration of the organ by ultrasonics, inter alia by the Doppler effect. It comprises a support for a piezo-electric transmitter/receiver transducer, and a cover which covers the transducer and at least that part of the support which is remote from the organ. The transmitting/receiving surface of the transducer is in contact with a surface of the support, which is interposed between the transducer means and the organ. The probe also has conductors attached to the transducer extending to the outside of the body to carry the information transmitted/received by the probe. The support and the cover have a configuration and shape such as to allow the probe to be removed from the body without a complex surgical operation, particularly by simply pulling from outside on the connecting means.

Abstract: There is disclosed a novel device intended to permit the regular and continuous release of chemical substances, including medicaments, and this, over a very long period of time, the release of the active substances following a predetermined kinetic effect from an insoluble polymeric matrix to a liquid medium which can be, particularly, that of an animal or human organism. The device has a specific density to remain in an animal rumen. There is also disclosed a method for treating animals by means of such devices.
