Introduction Peripheral nerve injuries are one of the most common injuries in the population and affect 3% of trauma patients. Unfortunately, full functional regeneration is a relatively rare phenomenon. Attempts to heal and regenerate damaged nerves are a frequent subject of research, especially when animal models are considered, and the results are not always satisfactory Aim of the study The aim of this study was to evaluate functional regeneration after sciatic nerve damage in mice treated with hyperbaric oxygen therapy and locomotor training, and to check the effectiveness of these methods. Materials and Methods The research material consisted of 75 mice with a damaged sciatic nerve. The mice were divided into three groups: H- subjected to hyperbaric therapy, T- subjected to training and K- not subjected to any therapy (control group). A functional gait analysis was performed using the CATWALK XT gait platform based on selected gait parameters. Results In the groups subjected to both hyperbaric therapy and training, the results of the analysis showed faster functional recovery. Statistically significant differences in the print area, print length, swing and SFI parameters were noted in the treated groups as opposed to the control group, while in the hyperbaric group of mice functional recovery turned out to be the most effective and fastest. Conclusion Mice of both groups (H, T) showed a faster recovery of sensory and motor functions in contrast to the control group not subjected to any treatment.

WstępCholestaza, inaczej zastój żółci, pojawia się wówczas, gdy dochodzi do zablokowania przepływu żółci. Obecnie wyróżnia się dwa rodzaje cholestazy: zewnątrzwątrobową i wewnątrzwątrobową. Do czynników wywołujących cholestazę zalicza się m.in.: alkoholowe i niealkoholowe stłuszczenia wątroby, infekcje, choroby dróg żółciowych, nowotwory dróg żółciowych czy choroby trzustki. Celem przeprowadzonych badań była ocena cech cholestazy i zmian w aktywności metaloproteinaz 2 i 9.Materiał i metodyMateriał badawczy stanowiło 36 szczurów samców szczepu Sprague-Dawley o masie ciała 350–420 g. Zwierzęta podzielono na 3 grupy badane i 3 grupy kontrolne, po 6 zwierząt w każdej. W grupach badanych wywołano model cholestazy zewnątrzwątrobowej. Zwierzęta z grup badanych i kontrolnych reoperowano kolejno po upływie 3, 7 i 14 dni. Aktywność wybranych metaloproteinaz określono metodą zymograficzną. Następnie ocenie mikroskopowej poddano preparaty histopatologiczne, oceniając charakterystyczne dla wątroby szczura cechy cholestazy.WynikiWszystkie grupy poddano analizie statystycznej z użyciem testu Kruskala i Wallisa dla wartości nieparametrycznych. Komputerowa analiza densytometryczna wyników zymografii uzyskanych z pobranego materiału wykazała aktywność MMP-2 i MMP-9. Znamienne statystycznie różnice oznaczono w przypadku MMP-2, stwierdzając jej podwyższoną aktywność w grupach I C, III C (*p < 0,05) w porównaniu z grupami kontrolnymi. Zaobserwowano tendencję wzrostową.WnioskiWraz z upływem czasu trwania cholestazy wzrasta aktywność MMP-2. Wyniki analizy histopatologicznej wybranych cech cholestazy wykazały, iż znamiennie wyższe oceny uzyskiwały zwierzęta w doświadczalnym modelu cholestazy.

Pain in the LS segment occurs in both young and old people. Stabilization training is gaining more and more supporters in returning to proper functioning. Central stabilization is the ability to maintain the correct body posture during static and dynamic movements. The DIAM system of dynamic interspinal stabilization of the spine is a minimally invasive procedure which, by inserting a silicone implant between the spinous processes, relieves the intervertebral joints, the intervertebral disc and reduces the pressure on the nerve structures. Continuation after the procedure is systematic physiotherapy. The aim of the study was to assess the impact of the implant and individually adjusted stabilization training of the lumbar-pelvic-hip complex in patients after dynamic interspinal stabilization with the DIAM method. The study was conducted on a group of 56 people who underwent a minimally invasive procedure and qualified from the 10th day after the operation. The stabilization training was selected individually for each patient, including the current state of health. The training was conducted once a week for four weeks. The conducted stabilization training of the lumbar-pelvic-hip complex turned out to be an effective method in recovery. There was a significant decrease in pain in the lower part of the spine among the examined patients. There was an improvement in physical activity and activities of daily living based on the Ronald-Morris scale. A decrease in the number of points was noted in all subjects. Fast, post-surgical rehabilitation therapy after using dynamic stabilization - DIAM, turned out to be a helpful method in faster recovery. It is reasonable to introduce early rehabilitation according to the scheme established by us after the DIAM dynamic stabilization procedure, as the period of return to work is reduced.
