Skin Damages

In spite of several decades of research, no effective treatment to skin injuries following exposure to sulfur mustard (HD) has yet been found. In the present study, the mouse ear vesicant model was applied to awake mice in order to evaluate the efficiency of potential anti-inflammatory treatments in preventing HD-induced skin damages. Clinical follow-up and histological evaluation were used to characterize the injuries to the skin and to evaluate the efficiency of the drugs that were applied. Thus, the extent of mouse ear oedema and the histopathological changes following a single application of 0.2 or 1 L of neat HD for 10 min (representing moderate and severe lesions, respectively), were monitored. Typical HD skin lesions were observed including epithelial and dermal damage. The development of the injury in mouse ears was found to be very similar to that reported in human skin. Screening of post-exposure topical steroids and non-steroidal anti inflammatory drugs (NSAIDs) proved that HD-induced inflammation could be diminished significantly as long as the treatment was applied during the early stages following exposure. A combined application of these drugs approved to be particularly effective in reducing inflammation.

 With the interaction of drugs belonging to different pharmacotherapeutic groups – nonsteroidal anti-inflammatory and antihypertensive – against the background of comorbid arterial hypertension with rheumatoid arthritis, the activity and safety of drugs may change with their combined use. Changes in the analgesic activity of nonsteroidal anti-inflammatory drugs, different in their selectivity to the types of cyclooxygenase (diclofenac, nimesulide and celecoxib), under the conditions of their long-term combined use with amlodipine in different periods of inflammation against the background of hypertension should be studied. Using the model of adjuvant arthritis comorbid with hypertension, in experiments on nonlinear mature white rats, the threshold of pain sensitivity has been determined by means of the “tail flick” test. Hypertension was caused by salt load with 1% sodium chloride solution for drinking with free access to it. Adjuvant arthritis was induced by the introduction of complete Freund’s adjuvant into the plantar aponeurosis of the hind limb of each animal with the established arterial hypertension. Against the background of arterial hypertension and comorbid pathology, there was an increase in the threshold of pain sensitivity observed in rats, which indicated the development of hypoalgesia. When combined, amlodipine enhanced the analgesic activity of diclofenac during 60 days of observation, slightly heightened the analgesic effect of nimesulide – up to 42 days, the effect of Celecoxib – in the acute period and the period of manifestation of adjuvant arthritis against the background of hypertension. The antinociceptive effect of diclofenac with amlodipine and celecoxib with amlodipine exceeded the analgesic effect of the combined nimesulide with amlodipine use against the background of comorbid pathology. The results obtained can be taken into account under the conditions of prescribing drugs belonging to the studied pharmacotherapeutic groups. It is likely that the use of diclofenac for analgesia against the background of comorbid conditions is only appropriate in the acute period of rheumatoid arthritis. The use of nimesulide to achieve an analgesic effect in the recurrence of rheumatoid arthritis against the background of hypertension is appropriate in the acute period and in the period of the inflammatory process attenuation. A highly selective coxib group cyclooxygenase-2 inhibitor, celecoxib, can reduce pain during the acute period of arthritis and during the manifestation of an inflammatory reaction that has developed against the background of arterial hypertension.

Relevance. Cryopreserved placenta extract (CPE) increase the resistance of the mucous membrane of the gastrointestinal tract to the damaging effects of nonsteroidal anti-inflammatory drugs. Preventive administration of CPE can reduce the ulcerogenic effect of meloxicam, ibuprofen, diclofenac sodium (DS) and others. There is evidence of CPE's own anti-inflammatory activity, which can be successfully combined with the pharmacological properties of nonsteroidal anti-inflammatory drugs, while improving their safety profile. Objective: to characterize the therapeutic activity of the combined use of CPE and DS according to hematological parameters in the model of experimental rheumatoid arthritis (RA). Materials and methods. Studies were performed on 28 nonlinear laboratory rats. The rats were divided into 4 groups: I (n = 7) – intact rats; II (n = 7) – rats with experimental RA; ІІІ (n = 7) – rats with experimental RA, treated with DN; IV (n = 7) – rats with experimental RA, treated with DN and CPE. Adjuvant arthritis was modeled by subplantar administration of complete Freund's adjuvant. Treatment was performed from 14 to 28 days. CPE was administered on days 14, 17, 20, 23 and 26, and DS – daily. Blood tests were performed on day 28 of the experiment. Results. The combined use of CPE and DS is accompanied by a more pronounced leveling of inflammatory signs by hematological parameters – erythrocyte clotting rate decreased by 72.2% (p<0.001), and the number of leukocytes decreased by 54.81% (p<0.001) relative to rats with adjuvant arthritis without treatment. There was a leveling of signs of anemia of chronic inflammation – the level of hemoglobin and erythrocytes increased (p<0,001) by 17.6% and 36.8%, respectively, relative to rats with adjuvant arthritis without treatment. Conclusions. The combined use of CPE and DS is superior in therapeutic activity to monotherapy with this nonsteroidal anti-inflammatory drug of experimental rheumatoid arthritis.
