ABSTRACT
We analyzed civilian gunshot wounds of maxillofacial area in 87 patients living in the Arkhangelsk region. It is noted that gunshot injuries most often occur as a result of the attempted suicide (45 cases (51,7%)), firearm associated crimes (33 cases (37,9%)) and careless handling with the weapon (9 cases (10,4%)). The most common wound canal features are described. In the majority of cases tangential gunshot wounds were seen (55 cases (63,2%)), penetrating wounds (19 cases (21,8%)) and perforating wounds (13 cases (15)). During the last years increased the number of gunshot injures by traumatic weapons (11 (12.6%)). It is recommended to take into consideration the direction and topography of the wound canals during the debridement.

The authors discuss 25 patients with gallstone ileus, which is a quite frequently encountered complication of cholelithiasis and is recorded in 0.64% of patient who underwent operation for calculous cholecystitis. The diagnosis and treatment of this complication have some specific features whose knowledge is extremely important in rendering emergency surgical care. Better results can be achieved by a timely and adequate diagnosis, individual choice of the operative method, and subsequent follow-up of the patients who were operated on. Regular medical examination and planned preventive treatment of patients with cholelithiasis are the main trends in the prophylaxis of this disease. Postoperative mortality was 24%.

UV-irradiation (lambda = 254 nm) of liquid aqueous solutions of deoxyguanosine in the presence of oxygen at pH less than 7 causes an intensive degradation of nucleoside. The quantum yield estimated from A254 decrease for the reaction mixture was found to be 1.5X10(-4) at doses to 150 E/mole. The rate of A254 decrease was found to grow with increasing doses. The structures of the products isolated from the reaction mixture after irradiation suggest that one of the ways of deoxyguanosine degradation is a breakdown of a purine cycle without splitting of N-glycoside bond. Simultaneously another type of photoinduced modification of guanine nucleus takes place, which is followed by appearance of free 2-deoxyribose. Deoxyguanosine degradation in both directions is kinetically one-step process proceeding with comparable quantum yields of approximately 1X10(-4).
