An important component of the development of degenerative changes in the spine is damage and disruption of the vital acti­vity of the paravertebral muscles. Objective. Based on the analysis of biochemical parameters of laboratory rats serum we evaluated the suitability of the studied models of dystrophic muscle tissue lesions for further study of the development of degenerative-dystrophic disorders in the spinal motor segments. Methods. Simulated: group I (5 female rats) — alimentary obesity by keeping for 3 months. on a high-calorie diet (hyperlipidemic diet); group II (5) — ischemia by ligation for 45 days of large back rectus muscles the with suture material that is not absorbed. Control — 5 intact animals of the same age and sex, which were kept on a standard diet. Serum levels of glycoproteins, haptoglobin, total chondroitin sulfates (CHS), glucose, cholesterol, low-density lipoproteins, triglycerides, total lipids, activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline and acid phosphatases, creatine phosphokinase were defined, thymol test was determined. Parameters were processed by the Fisher–Student method. Results. In the I group of rats, the content of glycoproteins, total cholesterol and lipids, low-density lipoproteins, triglycerides, glucose, CHS, ALT and AST activity, thymol test va­lues were increased and the level of creatine phosphokinase activi­ty was decreased. In animals of group II, an increase in serum activity of creatine phosphokinase, glycoproteins and CHS was recorded. Conclusions. Changes in the serum biochemical parameters of white rats recorded on a hyperlipidemic diet indicate the development of fatty degeneration, including in muscle tissue. Biochemical signs of degenerative processes in muscle tissue have been identified as a result of simulation of paravertebral muscle ischemia. Key words.

Virgin coconut oil (VCO) is a saturated fat with promising antidiabetic properties but its ameliorative effect on lipid profiles in diabetics is rarely reported. Therefore, in this study, a total of fifteen (15) male rats weighing 200–250 g were divided into 3 experimental groups (n=5). Group I (control) and Group II (diabetic control group) were fed a normal rat chow while Group III (diabetic test group) was fed a 10% VCO diet for 3 weeks. Group II and Group III were made diabetic by intraperitoneal injection of 150 mg/kg of alloxan. After 72 hours of injection, blood glucose was tested to confirm diabetes mellitus. After 3 weeks, the animals were sacrificed to collect blood samples for lipid profile analysis. The results showed a significant increase in concentrations of triglyceride, total cholesterol, low density lipoprotein, and very low density lipoprotein and decrease in concentration of high density lipoprotein in Group II when compared to Group I. Also, the concentrations of triglyceride, total cholesterol, low density lipoprotein, and very low density lipoprotein except high density lipoprotein significantly reduced in Group III when compared to Group II (P<0.01, 0.001). VCO consumption can be claimed to ameliorate lipid levels in diabetes mellitus.

This study aimed to assess potential feeding effect of camel milk curd mass and its mixes to experimental rat’s blood serum biochemical parameters, enzymatic activity and the peptide toxicity. Fifty healthy male Sprague-Dawley rats were divided into five groups (n = 10 each). Each group was fed with camel milk pure curd mass and its mixes for 16 days. At the end of the experiment, rats were sacrificed to collect the samples from the blood serum. Blood serum biochemical parameters total protein, cholesterol, glucose, albumin, triglycerides; the enzymatic activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase were determined on the A25 automatic analyser, and peptide toxicity analysed by the reference method. The statistical data have shown no significant differences in body weight gain in all groups. Total protein decreased in group II, IV, and V; however, it increased in group III compared to the control group. Cholesterol grew up in group II and it slightly increased in group V, dropped in groups III and IV compared to group I result. Glucose increased in groups II, III, IV compared to group I; still, group V results show a slight decrease. Albumin decreased in group IV, yet in group V it increased than the group I result. Simultaneously, groups II and III results were changed with less percentage. Triglyceride grew up in groups II, V, and it dropped significantly in groups III, IV compared to the control group. De Ritis ratio of enzymes in groups II, III, and IV fluctuated between 1.31 and 0.98 IU/L; however, group V demonstrated significant data versus group I. Diets peptide toxicity in all groups was lower than control group data. The experimental results indicated that curd mass from camel milk could be used as a pure or with additives and it did not discover the observed side effects.

Background. Pain syndromes developing as a result of degeneration of the lumbar segments of the spine constitute a significant problem in modern vertebrology. The results of the application of preoperative diagnostic provocative tests are contradictory, and therefore the mixed effectiveness of puncture surgical techniques is recorded.Objective. To develop an algorithm for the clinical and instrumental diagnosis of non-compression lumbar pain syndromes to optimize the use of puncture surgical techniques.Material and Methods. The study included 923 patients who underwent provocative diagnostic techniques on the intervertebral disk (IVD) and the arched joints (AJ) between 2012 and 2017. Taking into account clinical and instrumental data, the following are made: in group I (n=246) – laser IVD nucleoplasty, in group II (n = 287) – laser denervation of FJ, in group III (n = 390) – simultaneous use of laser exposure to IVD and AJ. We analyzed the dynamics of the level of pain in the lumbar spine and lower extremities according to The Visual Analogue Scale and quality of life according to The Short Form-36 (SF-36) questionnaire.Results. When performing provocative diagnostic tests, the minimum number of adverse effects was recorded: 3.2% in group I, 2.4% in group II, and 2.1% in group III. After puncture methods of surgical treatment, a significant persistent decrease in the severity of preoperative pain was observed both in the lumbar spine (p = 0.002, p = 0.005 and p = 0.004, respectively) and in the lower extremities (p = 0.003, p = 0.001 and p = 0.005, respectively) A significant improvement in the physical and psychological components of health was also established in group I (p = 0.02 and p = 0.01, respectively), in group II (p = 0.01 and p = 0.03, respectively) and group III (p = 0.03 and p = 0.02, respectively).Conclusion. In the presence of neuroimaging parameters of IVD according to C. Pfirrmann III–IV and protrusion size 4–6 mm, minimal degenerative changes in the AJ according to A. Fujiwara I–II and D. Weishaupt I–II, as well as a positive disruption test, it is possible to perform laser nucleoplasty. In case of detection of neuroimaging data of IVD according to C. Pfirrmann I–II and protrusion size less than 4 mm, moderately pronounced degenerative changes in the AJ according to A. Fujiwara II–III and D. Weishaupt II–III, as well as positive paraarticular stimulation of AJ, laser denervation of AJ is recommended. When determining, according to neuroimaging data, moderate degenerative changes in IVD according to C. Pfirrmann over III and protrusion size 4–6 mm, as well as degeneration of AJ according to A. Fujiwara more than II and D. Weishaupt more than II, positive of samples and paraarticular stimulation of AJ, it is advisable to perform simultaneous surgical intervention in the volume of laser IVD nucleoplasty and laser denervation of AJ.

Background: The study evaluates the effect of a high supplemental dose of ascorbic acid (AA) on plasma concentrations of total cholesterol (TC), triglycerides (TG), total lipids (TL), and lipoprotein fractions high-density, very-low-density-, and low-density lipoprotein (HDL, VLDL, LDL) in guinea pigs fed with atherogenic diet. Methods: Group I consisted of 5 normally fed guinea pigs plus a low dose of AA (1 mg/100 g/day), group II consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a low dose of AA (1 mg/100 g/day), and group III consisted of 7 guinea pigs fed with food enriched with 2% cholesterol plus a high dose of AA (30 mg/100 g/day). Cholesterolemic factors concentrations were determined after nine weeks. Results: Concentrations of TC, TG, TL, LDL, and VLDL were increased in group II compared to group I (p < 0.01 for all differences). Supplementation with a high dose of AA resulted in decreased concentrations of TC (p < 0.01), TG (p < 0.01), TL (p < 0.01), and LDL (p < 0.01) in group III compared to group II. Additionally, concentration of HDL was increased in group III compared to group II (p < 0.01). Conclusion: High-dose AA supplementation to an atherogenic diet decreases concentrations of TC, TG, TL, and LDL and increases concentration of HDL compared to low-dose AA.

The aim of the work was to study the effect of vanadium citrate on the activity of glucose-6-phosphate dehydrogenase, lactate dehydrogenase, estradiol content and to establish correlations between the activity of the studied enzymes and the estradiol content in pregnant female rats under the effect of vanadium compound. The study was carried out on 25 female Wistar rats, divided into five groups: group I - non-pregnant, group II - pregnant consuming pure water without additives, groups III, IV, V - females which during the mating and pregnancy periods received the solution of vanadium citrate at the concentrations of 3.75, 15.63 and 62.5 μgV/kg of body weight, respectively. Glucose-6-phosphate dehydrogenase, lactate dehydrogenase and estradiol content increase in pregnant females of group II compared to group I of non-pregnant animals. In pregnant females, the effect of vanadium citrate resulted in the decrease in the activity of glucose-6-phosphate dehydrogenase and lactate dehydrogenase in the blood of animals in groups IV and V, and the content of estradiol in the animals of all three experimental groups (III, IV, V), compared to group II of pregnant females. The values of glucose-6-phosphate dehydrogenase activity in the animals of group IV, which received the solution of vanadium citrate at the concentration of 15.63 μgV/kg of body weight, was similar to that of the animals in group I. This may indicate the normalizing effect of vanadium citrate on the activity of glucose-6-phosphate dehydrogenase at the indicated concentration, which is probably due to the ability of the vanadium microelement to inhibit the activity of this enzyme. Vanadium citrate at the concentration of 15.63 μgV/kg of body weight caused the recovery of the enzyme activity to the values of the activity in group І.

Abstract Introduction Aging is a normal physiological process that affects all organs in the body including the cerebellum. Metformin is an anti-diabetic drug that is used in some age-related diseases. Regenerative medicine using adipose tissue derived mesenchymal stem cells (ADMSCs) is an emerging promising strategy. Aim to compare between the role of ADMSCs and metformin on the age-related structural changes of the cerebellum in female albino rats. Materials and methods Fifty-five female rats of different ages (4, 12 and 24 months) were included in this study. They were divided into three groups according to their ages: Group I (Adult rats), Group II (Old rats) and Group III (Senile rats). Group II and Group III were subdivided into three subgroups, Subgroup a: rats were left without treatment, Subgroup b: rats were given a single dose of 1X106 ADMSCs via tail vein. Subgroup c: Rats received300 mg/kg metformin/day orally. Rats were sacrificed after four weeks. The cerebellum was collected and processed for H&E, Toluidine blue and immuno-histochemical reaction using glial fibrillary acidic protein (GFAP). Results Histological examination of the cerebellum of the subgroups IIa and IIIa revealed age-related structural changes in comparison to group I. Purkinje cells appeared distorted with irregular outline. Some Purkinje cells were seen shrunken while others appeared ballooned. Focal loss of Purkinje cells was also noticed. Granular layer contained small widely separated granule cells. GFAP reaction revealed an apparent decrease in number of astrocytes and their processes. The structural changes were more obvious in subgroup IIIa. In ADMSCs treated subgroups (IIbandIIIb); more noticeable improvement of these changes was noticed compared to the corresponding metformin treated subgroups (IIc and IIIc). Conclusion ADMSCs was more effective than metformin in preventing some age-related structural changes of the cerebellum.

Low density lipoproteins (LDL) extracted from hens egg yolk (EY) has been studied over EY based extender for liquid storage of mithun semen with the objective to explore the use of LDL in place of EY. Physio-morphological attributes (PMAs) and mobility and velocity parameters were measured by computer assisted sperm analyser (CASA). Leakage of intracellular enzymes, activity of total antioxidants and lipid peroxidation following liquid storage (5oC) of mithun semen were studied. Fifty ejaculates were collected through transrectal massage method from matured mithun bulls and based on the mass activity and individual motility; the semen samples were splited into good and poor quality and diluted with the tris citrate glycerol (TCG) extender and were splited into three equal aliquots: Group I: Control, EY; Group II and Group III contained 8 and 10% LDL (w/v), respectively. PMAs, intracellular enzymatic leakage and biochemical profiles were evaluated at 5°C following 10hrs incubation. Result revealed a significant (p less than 0.05) improvement in PMAs, CASA parameters and cholesterol content of spermatozoa as well as reduction in leakage of intracellular enzymes, oxidative stress in Group II than control and other treatment group. It was concluded that addition of 8% LDL holds a clear advantage over EY or 10% LDL in liquid preservation of mithun semen.

This study was carried out to investigate smoke-induced structural and biochemical changes and protective effects of co-administered melatonin and vitamin C in the kidney. Twenty-four Wistar adult female rats were used in this study. Animals were divided into four groups. The first group rats were used as control. The second group of rats inhaled cigarette smoke. Smile smoke inhaling third and fourth group rats received melatonin and vitamin C, respectively. At the end of experimental study, kidney tissues and blood samples were taken under ether anesthesia. Tissues were prepared and examined by light microscopy. Malondialdehyde and glutathione levels and catalase activity were determined. By light microscopic observation, a decrease of Bowman space of some renal corpuscles, foamy-like tubules, dilatation and congestion of the peritubuler vessels, and atrophy of the some renal corpuscles were observed in group II. In groups III and IV melatonin and vitamin C relatively protected the kidney tissue against smoke intoxication. Biochemical examination showed that malondialdehyde and glutathione levels and catalase activity in group II were higher than in group I. Melatonin and vitamin C injection to group III and IV caused a decrease in malondialdehyde and glutathione levels. Catalase activity did not change in these groups. We have shown that cigarette smoke inhalation caused structural changes in the kidney. However, melatonin and vitamin C administration produced in some degree protection against smoke-induced damage.

PURPOSE: To evaluate the protective action of alpha-tocopherol in ischemia/reperfusion injuries of pelvic member of rats. METHODS: Thirty adult male rats of the Wistar strain were randomized into three experimental groups of 10: Group I - control group with no ischemia or reperfusion. Groups II and III - four hours of ischemia and of hours of reperfusion by means of clamping of the infrarenal aorta. The animals of Group II were treated with saline and those of Group III were treated with i.v. alpha-tocopherol (50 mg/kg). Parameters studied were biopsies of the soleus muscle, dosing of creatine phosphokinase, lactate dehydrogenase, potassium, calcium and arterial blood gasometry. RESULTS: The results of biopsies of the soleus muscles studied by optical microscopy, were not significant in terms of presence of edema among the three groups studied. Variables inflammation and necrosis were not observed, therefore cannot be statistically analyzed. As to dosing of calcium and lactate dehydrogenase, the pH, pO2 and pCO2 values were not significant for all groups studied. We observed that the levels of potassium (Group II > Group I, Fcalculated = 5.84; Fcritical = 3.33), creatine phosphokinase (Group II > Groups I and III, Hcalculated = 13.92; Hcritical = 5.99) and bicarbonate (Groups I and III > Group II, Hcalculated = 11.98; Hcritical = 5.99) presented significant results among groups. CONCLUSION: From the serum biochemical perspective, the treatment with alpha-tocopherol has attenuated the metabolic injuries in the ischemia/reperfusion syndrome in this experimental model.
