The present invention belongs to the technical field of biomedicine, and relates to use of linoleic acid in the preparation of a drug for improving the sensitivity of Gram-positive bacteria to an antibiotic. It has been discovered for the first time that the combined use of linoleic acid and an antibiotic can significantly improve the sensitivity of Gram-positive bacteria to the antibiotic. In vivo study data have shown that the combination of linoleic acid and the antibiotic can not only improve the survival rate of mice infected with Gram-positive bacteria, but also enhance the ability of the mice to clear Gram-positive bacteria. Furthermore, formulating linoleic acid and the antibiotic into an anti-infection composition can, in one aspect, achieve a significant clinical anti-infection effect, and in another aspect, prolong the post-antibiotic effect. Moreover, linoleic acid is an essential fatty acid in human and animal nutrition, with high nutritional value, and it has been widely used in food and pharmaceutical products, demonstrating high safety.

The present application relates to the field of pet feed, and discloses a maintenance ration formula for improving the smoothness of dog hair. The formula comprises base ration particles and lipid microcapsules attached to the surface of the base ration particles; the lipid microcapsules encapsulate a core material composed of essential fatty acids and ceramides, have a double-layer wall material structure, and the outer layer is acid-resistant plant gum and the inner layer is lipase-sensitive phospholipid; the microcapsules are attached to the surface of the puffed base ration by low-temperature vacuum spraying. The present application makes the microcapsules resistant to gastric acid and releases the core material under the action of duodenal lipase, targets and enriches in sebaceous glands through the lymphatic system, solves the problems of low lipid delivery conversion rate and insufficient substrate of sebaceous glands, improves the proportion of sebaceous gland ceramides, and reduces the hair friction coefficient.

This invention relates to ketogenic nutritional powder containing medium- and long-chain fatty acid triglycerides, its preparation method, and its application. It belongs to the field of food science and engineering technology. It uses enzymatically synthesized medium- and long-chain fatty acid triglyceride structured lipids as the sole fat source, which is different from the traditional physical mixture of long-chain triglycerides and medium- and long-chain oils. Medium-chain fatty acids and long-chain fatty acids are simultaneously bound to the same glycerol molecule. Fatty acid digestion and absorption are synchronized and metabolized, which can give full play to the synergistic nutritional advantages. It retains the characteristics of medium-chain fatty acids that provide rapid energy and are not easy to accumulate in body fat, while also supplementing essential fatty acids such as linoleic acid and α-linolenic acid. At the same time, it overcomes the disadvantages of pure medium-chain fatty acid oils that cause great gastrointestinal irritation and have a low smoke point.

This patent relates to a novel phytotherapeutic compound for topical use, specially formulated for the treatment of burns. The innovation lies in the use of a formulation that combines passion fruit leaves (Passiflora sp.) and refined pork fat, providing a natural and effective approach to the management of skin burns. Passion fruit leaves are processed by infusion to extract flavonoids, known for their anti-inflammatory and antioxidant properties, which reduce inflammation and oxidative stress in damaged tissue, facilitating healing. Refined pork fat, chosen for its rich composition of essential fatty acids and its emollient properties, serves as the base for the ointment, helping to absorb the active ingredients and to form a protective barrier that minimises transepidermal water loss and protects against infections. The method of obtaining the compound involves frying the fat to extract lipids, followed by filtration for purification. Subsequently, passion fruit leaf extracts are combined with the purified fat and the mixture is evaporated until it reaches the appropriate consistency for an ointment. This composition not only accelerates the healing of burns, but also significantly alleviates the pain and discomfort associated with such injuries. The compound offers an effective and safe alternative to conventional burn treatments, standing out due to its simplicity, efficacy, and use of natural ingredients, making it particularly valuable in regions with limited access to medical resources.
