The author of this paper, in order to diagnose the imbalance of connective tissue metabolism, has analyzed the results of laboratory tests of blood and urine according to biochemical parameters of the patients with closed craniocerebral injury (CCI) with diff erent severity and has established their clinical and diagnostic value. 100 children who had closed craniocerebral trauma were examined. There were 79 boys (79 %) and 21 girls (21 %), aged from 3 to 17 years among them. Distribution of children into groups was conducted according to the clinical forms of craniocerebral trauma: Group I — closed craniocerebral trauma, cerebral concussion — 50 children (50 %), average age (14,6 ± 2,5) years; Group II — closed craniocerebral trauma with cerebral contusion of moderate severity — 20 children (20 %), average age (13.5 ± 4.5 years); Group III —closed craniocerebral trauma with severe cerebral contusion — 30 children (30 %), average age (14.5 ± 3.5 years). Chondroitin sulfates were determined in the blood serum of patients — according to the М. Németh-Csóka method in the modifi cation of L. I. Slutskyi, fraction of glycosaminoglycans (GAG). The content of oxyproline was determined in the urine — by the reaction with chloramine-B, uronic acids — by the reaction with carbazole. In case of mild CCI (cerebral concussion), the indicators of biochemical studies of the blood and urine remained within the normal range, while with the increase in the severity of the injury, we observed an increase in chondroitin sulfate, and a decrease in the level of general GAG, its II and III fractions, and an increase in oxyproline in the urine, indicating the dysgenesia of the connective tissue metabolism and which may be the basis for the unfavorable course of closed craniocerebral injury of children during the rehabilitation period. Detection of changes in the connective tissue metabolism allows additionally predict the course of the disease in the period of rehabilitation and the possibility of recovery of children after CCI. Key words: children, craniocerebral injury, connective tissue dysgenesia, mucopolysaccharides, oxyproline.

Introduction: There are many methods for diagnosis and treatment of knee joints osteoarthritis in modern orthopedics. The infrared radiation is one of the most popular and effective methods though it needs experimental substantiation on rats. The aim: Experimental definition of the effectiveness of the proposed method of conservative treatment of knee joints osteoarthritis using sodium diclofenac, glucosamine hydrochloride and infrared laser radiation, on the basis of biochemical markers of connective tissue metabolism in rats. Materials and methods: Experimental studies were performed on 40 white male rats. A part of rats received infrared laser radiation in addition to diclofenac sodium and glucosamine hydrochloride. Results: Using a complex of infrared laser radiation and glucosamine hydrochloride and diclofenac sodium in conservative treatment of rats with experimentally induced knee joints osteoarthritis rats after 24 days of treatment. Treatment with the above-mentioned scheme resulted in a significant reduction in the content of glycoproteins (28.5%), chondroitin sulfates (26.1%), alkaline phosphatase activity (32.3%), and I and II fractions of glycosaminoglycans, namely chondroitin-6- (28.7%) and chondroitin-4-sulfate (40.3%). Moreover, these indicators of the studied markers approached the level of intact animals. Conclusions: Changes in biochemical markers of connective tissue in rats during experimental knee joints osteoarthritis indicated a higher efficiency of the treatment regimen with the use of low-intensity infrared laser radiation compared with exclusively drug therapy.

Abstract Pelvic organ prolapse (POP) in lysyl oxidase like-1 knockout (Loxl1 KO) mice occurs primarily in parous mice and is rare in nulliparous mice. We determined the effect of Loxl1 deficiency on postpartum regulation of connective tissue metabolism genes and degradative enzyme activity in the vagina at 20 days gestation or 4 h, 48 h, 7 days, 15 days, 25 days, 7 weeks, or 12 weeks postpartum. Nulliparous Loxl1 KO and wildtype (WT) mice aged 11, 18, or 23 weeks were controls. Gene expression and enzyme activity were assessed using real-time quantitative reverse transcription PCR and fluorescein conjugated gelatin zymography, respectively. Parity, but not aging, had a significant influence on gene expression both with time postpartum and between KO and WT mice. Mmp2, Timp1, Timp2, Timp3, Timp4, Col1a1, Col3a1, Acta2, and Bmp1 were differentially expressed between KO and WT mice. Correlational analysis of gene-gene pairs revealed 10 significant differences between parous KO and WT groups, 5 of which were due to lack of co-expression of Bmp1 in KO mice. The overall enzyme activity that could be attributed to MMPs was significantly higher in WT compared to KO mice both 25 days and 12 weeks postpartum, and MMP activity was significantly lower 15 days and 25 days postpartum compared to KO nulliparous controls, but not WT. These findings suggest that Loxl1 deficiency combined with parity has a significant impact on postpartum regulation of connective tissue metabolism, particularly as it relates to co-expression of Bmp1 and altered proteolytic activity.
