Objective. To study up the possibilities of improvement of the treatment results in patients, suffering an acute pancreatitis, using the method of delivery of antibiotic to pancreatic gland. Materials and methods. The authors have proposed and conducted the experimental investigation on 20 male rats, consisting of the manners to deliver of ceftriaxone towards pancreatic gland. Results. Taking into account the enhances antibacterial efficacy of pancreatic gland homogenate, than while antibiotic delivery using other methods, there appear that lymphotropic therapy owes a targeted character and must be considered a perspective one. Conclusion. To three groups of laboratory animals ceftriaxone was prescribed intramuscularly, intraperitoneally and in accordance to lymphotropic method. To the control group of laboratory animals, the fourth one, antibiotic, was not applied. The zone growth retardation for E. Coli, while application of lymphotropic method, comparing with intramuscular and intraperitoneal methods of the preparation delivery, was enhanced.

Summary. Introduction. Warming in Ukraine leads to the displacement of warm zones to colder ones, and at the same time, to the removal of colonization zones of many insectivores, which are carriers of rare diseases in Ukraine. Materials and methods. Clinical observation of Dirophilaria immitis of the pleural cavity is given. The patient was treated for «pneumonia» by a family doctor and a district therapist for two months. Only after consultation with a thoracic phthisiosurgeon was diagnosed with chronic pleural empyema and performed pleurectomy. A living string-like body was found in the pleural sac, which turned out to be D. immitis. Results and discussion of observations. The diagnosis of «pneumonia» was established on the basis of the clinical picture without a detailed physical and radiological examination, which is methodologically erroneous. If the patient was observed or consulted by a specialist, surgery could be performed earlier, in the first stage of chronic disease. Conclusions. In the differential diagnosis of pleural diseases, a detailed physical and radiological examination in two projections and anamnesis leads: human bites by mosquitoes in wet places, as they are the final hosts of D. Immitis and D. repens.
