[Mechanisms disordering wound healing on the lip after bilateral crossing of the inferior alveolar nerve and experimental validation of correction methods].

The mechanisms of lip wound healing after bilateral crossing of the inferior alveolar nerve (IAN) were studied on Chinchilla rabbits in 3 experimental series, 6 animals per series. In group 1 bilateral crossing of IAN was carried out, in group 2 bilateral crossing of IAN was paralleled by removal of a mucous flap in the middle of the lower lip, and in group 3 the same wound as in group 2 was created, after which the wounds in this group were daily treated with a special ointment and a single injection of lidocaine (1% solution) under the wound. The nerve crossing led to development of ulcer on the lip with degenerative changes in the vascular walls, destruction of nerve fibers, and fragmentation of some axial cylinders.

[An immunoenzyme method for determining IgA antibodies to lipopolysaccharide in secretions in the diagnosis of shigellosis].

IgA antibodies to S. sonnei and S. flexneri lipopolysaccharides (LPS) in secretions, as well as Escherichia coli LPS in coprofiltrates of children with acute diarrhea, were determined with the use of enzyme immunoassay (EIA).

[The clinical picture and treatment of chronic lip fissures].

Fifty-seven patients with chronic recurrent labial fissures were administered multiple-modality conservative therapy including procaine blocking. The therapy was effective in 85 percent of patients: no recurrences were recorded over 5 years. The described method for therapy of chronic recurring labial fissures is recommended as a method of choice.
