Abstract Background Skeletal muscle injuries are one of the most common injuries occurring in sport medicine varies from 10% to 55% of all injuries. Phases of muscle injuries includes a series of complex stages including inflammation, regeneration and remodeling. Treatment of the injuries is based on conservative measures as rest, elevation, physical therapy and non steroidal anti-inflammatory medications. Many injection protocols have been proposed for the treatment of muscle lesions as corticosteroid injection. Recently prolotherapy appears to have a safety profile comparable with other injection procedures. Aim of the work The aim of the present work is to determine the efficacy of dextrose prolotherapy in treatment of skeletal muscle injury in adult male albino rats. Material and methods Sixty six adult male albino rats were used in the study. They were divided into control (group I) and experimental groups. Control group: rats were left without any intervention. The experimental group was group II that was divided into sham operated group in which skin incision was done in the left hindlimb without injury to gastrocnemius (group II`) and muscle injury group in which transverse cut injury across the midbelly of the gastrocnemius muscle of right hindlimb was done (group II``) and group III that was divided into lidocaine injected group in which skin incision in lefthindlimb was done without injury to gastrocnemius followed by injection of 0.3 ml 1% lidocaine was injected across the muscle (group III`) and muscle injury treated with dextrose prolotherapy group in which a transverse cut injury across the midbelly of gastrocnemius of right hindlimb was done followed by injection of 0.1 ml of dextrose prolotherapy of mixture of 0.1ml of 12.5% dextrose and 0.3 ml of 1% lidocaine (group III``). The animals were received 6 injections of lidocaine and dextrose prolotherapy at 5 days interval (starting from day 0 to day 25). In group II and III, muscle specimens were taken at 5,12 and 28 days and processed for light microscope Results Examination of Group II``A (5 days untreated group) showed intense infiltration of mononucleated inflammatory cells intermingling with dispersed myoblasts and macrophages. Group II`` B (12 days untreated group) showed regenerating myotubes intermingling with mononuclear inflammatory infiltrate and macrophages. Group II``C (28 days untreated group) showed some muscle fibers with peripherally elongated nuclei while others showed centrally vesicular ones. Examination of group III``A (5 day treated group with prolotherapy) showed longitudinal regenerating myofibers with multiple rows of internal vesiculated nuclei. Group III``B (12 days treated group) showed newly formed myofibers with incomplete striations together with well developed newly formed striated longitudinal muscle bundles with peripheral flattened nuclei, group III``C (28 days treated group) showed cross striated muscle fibers with the appearance of elongated vesicular nuclei. Conclusions dextrose prolotherapy was effective in soft tissue healing as it accelerated myoblast proliferation and differentiation

Olanzapine is an antipsychotic drug effective in the treatment of stress-associated psychiatric illnesses, but its effect on the spleen remains unclear. Vitamin C is essential for the optimum function of the immune system. We aim to investigate the effect of Olanzapine on spleen structures and to assess the protective effect of vitamin C. Forty adult male albino rats were divided into four groups: group (I), a control; group (II), rats were given vitamin C at 40 mg/kg body weight; group (III), rats were given Olanzapine at 2 mg/kg body weight; and group (IV), rats were given vitamin C and Olanzapine at the same dose of group (II) and group (III) for one month. The hematoxylin and eosin (H&E) of the olanzapine treated group showed focal areas of cellular depletion and a decrease in the size of the white pulp. The red pulp was expanded and showed marked congestion and dilatation of blood sinusoids. Cluster of differentiation 3 (CD3) was significantly reduced, however both tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF) were significantly higher. The administration of vitamin C repaired structural and immunohistochemical changes via increased CD3 and decreased TNF-α and VEGF. Therefore, the oxidative and the inflammatory pathways may be the possible mechanisms underlying olanzapine immunotoxicity. Vitamin C exerted immune modulator and antioxidant effects against olanzapine.

Abstract Background Skeletal muscle injuries are frequently encountered in athletes and military personnel. Incomplete functional recovery of these injuries usually occurs due to fibrosis of the skeletal muscle. Recently, oral administration of losartan antihypertensive drug was claimed to have a role in improving skeletal muscle healing, but still to be furtherly investigated. Aim of the work This work aimed to assess the healing effect of losartan on the histological structure of induced lacerated skeletal muscle fibers of adult male albino rats. Material and Methods Forty male albino rats were used in this study. They were divided into three groups: Group I: served as a control group and included 15 adult rats. Group II (muscle laceration group): consisted of 15 rats that were subjected to muscle laceration injury. They were subdivided into subgroup IIa: consisted of five rats that were sacrificed one day after injury, subgroup IIb: it included 10 rats that were left for spontaneous recovery for two weeks after injury. Group III (losartan-treated group): it consisted of 10 rats that were subjected to muscle laceration injury then they received oral losartan from day three till end of experiment. All rats, except rats of subgroup IIa, were sacrificed two weeks after injury. Right gastrocnemius muscle specimens were taken and processed for light microscopic examination by H & E and Masson's trichome stains as well as morphometric and statistical analysis. Results In group II, there was almost complete affection of myofibers at site of injury after 1 day of induced laceration in the form of myofibers fragmentation, disorganization and distortion with apparent mononuclear cellular infiltration mainly neutrophils and macrophages. After 2 weeks some myofibers were seen distorted and ended abruptly into connective tissue, others were branched with unclear striations. Mononuclear cellular infiltration between myofibers and apparent dilated blood vessels at laceration site were also noticed. A significant increase in collagen fibers deposition between regenerating muscle fibers (p<0.05) was also demonstrated. Treatment of the muscle laceration by losartan in group III showed apparent partial improvement in the form of significant decrease in collagen fibers deposition (p<0.05) and apparent decrease in mononuclear cellular infiltration as compared to that of group II. Also, some of the regenerated myotubes were noticed with chains of central nuclei. Conclusion Excess collagen fibers deposition between myofibers hinders regular arrangement of generating myotubes. Losartan might enhance muscle regeneration through decreasing collagen fibers deposition. However, it needs longer duration to assure complete muscle healing.

BACKGROUND: Sofosbuvir (SOF) was published in 2013 as a part of first-line treatments for hepatitis C virus (HCV); it has activity against all genotypes with extrahepatic adverse effects have recently arisen. AIM: Investigating sofosbuvir-induced alterations in the rat submandibular salivary gland (SMSG). METHODS: A group of 80 adult albino rats weighing about ± 150 gm were used in the experiment. The rats were divided into 3 groups: Group I (control group) received distilled water, Group II (experimental group) divided into 2 subgroups and received SOF 40 mg/kg/day dissolved in distilled water for 1 and 3 months and Group III (recovery group) allowed for 1 month of recovery after SOF withdrawal. All animals were sacrificed; the SMSG was dissected, and specimens were examined histologically and ultra-structurally. RESULTS: Compared to Group I, Group II subgroup (1) showed acinar and ductal vacuolisation, discontinuity of the epithelial lining associated with retained secretion and congested blood vessels. These changes were found to be exaggerated in the subgroup (2) accompanied by acinar and ductal shrinkage, interstitial oedema, haemorrhage, chronic inflammatory cells infiltration and loss of gland compactness. Amelioration of the histological changes was detected in Group III after SOF withdrawal. The ultrastructural examination confirmed the histological results. CONCLUSION: SOF had induced apparent alterations in the structure and ultrastructure of SMSG. The SOF-induced alterations were time-dependent, attributed mainly to mitochondrial toxicity and partially ameliorated by its withdrawal.

The present study aimed to investigate the ameliorative effects of fenugreek seeds and curcumin on hematotoxicity induced by nicotine in male albino rats. 30 male F-344/NHsd Fischer rats, weighing from 180 to 200g were used in the present study. The animals were divided into five groups (6 rats for each); Group I (control group), Group II (nicotine treated group), Group III (nicotine/fenugreek seeds co-administered), Group IV (nicotine/curcumin co-administered), and Group V (nicotine/curcumin& fenugreek seeds co-administered). At the end of the experimentation and 24 hours after the last dose, all animals were anaesthetized with ether and blood samples were collected by heart puncture. The samples were collected in clean dry tubes containing the anticoagulant substance EDTA and used for the hematological studies. The results showed that the animals treated with nicotine for 4 weeks showed a significant decrease in RBCs count, hemoglobin concentration, hematocrit value, MCH, MCHC, and platelets count, and increased MCV and WBCs count as compared to the control group. Co-administration of nicotine with fenugreek and/or curcumin caused improvement in all hematological parameters when compared with nicotine group. It can be concluded that nicotine had a strong effect on the hematological parameters. The ingestion of fenugreek and/or curcumin prevent the hematoxicity induced by nicotine. The current study suggests that fenugreek and curcumin may be useful in combating free radical-induced hematotoxicity induced by nicotine.

Abstract Introduction Achilles tendon tears cause severe impairment in patient mobility and productivity, causing significant reduction in the quality of life. Many complications are associated with the tendon healing process such as peritendinous adhesions and excessive fibrotic scars. Unsatisfactory results appeared with the existing medical and surgical treatments to regain full tendon structure and function. Amniotic membrane is avascular, and characterized by low immunogenicity, anti-inflammatory, antiscarring properties. These criteria render it as a natural biological substitute and a novel therapeutic alternative for tendon tears. Aim: The aim of the work was to study the effect of human amniotic membrane graft application on the repair of induced Achilles tendon tear. Material and methods Fresh human amniotic membrane (AM) grafts were prepared from harvested human full-term caesarian sections-delivered placentas. Thirty adult male albino rats were divided into 3 equal groups (n = 10); group I (control group), group II (tendon tear group) and group III (AM treated group). After anesthesia, a full thickness transverse incision was induced in the rat right Achilles tendons of group II and III. Human derived amniotic membrane graft measuring 1 cm2 was applied circumferentially on the tendon tear in group III. Rats were sacrificed after 28 days. Results After the tendon tear, the untreated group (II) showed gradual accumulation of fat cells replacing the collagen bundles in focal areas. Areas of mononuclear cellular infiltration were demonstrated. The AM-treated group showed many thick parallel regularly arranged collagen fibers with a significant increase in the collagen fibers area percentage. It also showed apparent increase in tenoblasts with regular organization and apparent decrease of mononuclear inflammatory cells. Conclusion This study demonstrated the potential therapeutic role of the application of human amniotic membrane grafts in the repair of Achilles tendon tears, suggesting a future alternative therapy for patients suffering from Achilles tendon tears.

This study was performed to investigate the hypoglycemic properties of Propolis and their possible role on pancreatic's tissue. Diabetes mellitus was induced in 45 adult male albino rats and the animals were divided into three groups; Negative control group received standard diet; Positive group diabetic untreated group; Propolis treated group supplemented with (0.3 g/Kg/day) for 2 weeks after the induction of diabetes by streptozotocin. At the end of the experiment, blood was collected from the abdominal aorta. A heparinized tube was used for collection of plasma for measurement of lipid peroxidation products, insulin, glucagon and fasting blood glucose. Pancreas were isolated and stained with hematoxylin and eosin (HE), histoimmunological and morphometric factors were studied. The results of this study showed that Propolis was able to reduce blood glucose significantly compared with the diabetic untreated group. Hypercellularity and density of B cells increased in pancreatic tissue, islets size and percent of B cells increased significantly in Propolis treated group which may signify regeneration of islets or B cells in Propolis treated rats. In the current study, we have demonstrated that, both structural and functional improvements of pancreas. Further researches are highly needed to clarify the specific molecular and cellular targets of various constituents of Propolis.

Aims: This study was done to clarify the effects of hyperbaric oxygen therapy on the harmful changes of liver and pancreas of adult male albino rats after dexamethasone induced diabetes. Place of Study: Faculty of medicine, Tanta University, Egypt. Methodology: Thirty two adult male albino rats were divided into; group I (control), group II (Hyperbaric oxygen treated), Group III (induced diabetes - non treated group) and Group IV (induced diabetes + Hyperbaric oxygen treated group). Induction of diabetes was done by dexamethasone injection for ten days. Hyperbaric oxygen was given once per day for 5 sessions in group II and IV. The rats of all groups were sacrificed after the 20th day. Specimens of liver and pancreas were subjected to microscopic examination. Results: Rats from group III showed a highly significant increase of blood glucose compared to the controls. Treated rats in group IV showed highly significant decrease in blood glucose compared to group III. Hepatic steatosis and histopathological changes of pancreatic acini and islets of Langerhans were noticed in untreated diabetic rats. Group IV after Hyperbaric oxygen therapy revealed partial improvement of histological and ultrastructural effects of diabetes on the liver and pancreas. Conclusions: HBOT is partially effective in reducing blood glucose level and improving the hazardous effect of untreated diabetes on the histological and ultrastructural architecture of the liver and pancreas of male albino rats.

Background: Limited research studies are reported regarding the toxicological effect of different herbal medicine already used in different countries. Objective: This research study was planned to examine the changes in liver (biochemical and histological) associated with oral administration of somina (acute and sub-acute) in rats. Methodology: Group– I served as control (saline), while other groups (II, III) were daily treated with somina at different doses of 0.285g/kg (group – II), 10g/kg/day (group – III), for 14 (set I), 21 (set II), and 30 (set III) consecutive days.  Each group contains 12 rats. During the study period, signs and behavioral changes, mortality, were observed. At the end of study period, blood sample was drawn directly from heart, for the estimation of liver enzymes: Bilirubin (BIL), alkaline phosphatase (ALP), serum glutamic pyruvic transferase (SGPT), aspartate aminotransferase (SGOT), Albumin (ALB) and total protein (TP). The liver was carefully dichotomized, weighed, and further processed for histopathological analysis. Results: Herbal drug somina was claimed to be practically non-toxic as in rats no mortality was recorded after the oral administration of somina (14, 21 and 30 consecutive days). Liver profile showed non-significant changes in treated group- II and III (P > 0.05), as compared to the control (group- I). The histopathological examination did not reveal any deteriorative effect. Conclusion: It was concluded that oral administration of somina did not produce any significant detrimental effects on rat liver (biochemical and histopathological parameters), even at doses of 10g/kg/day indicating its safe use.

<p>The aim of this study was to evaluate diuretic activity of aqueous methanolic extract of <em>Euphorbia granulate</em> in rats. Albino rats were divided into five groups. Group I served as reference, Group II as standard and Group III, IV and V served as test. The three doses of extract (30, 50 and 100 mg/kg) were given to rats (i.p) in acute diuretic model. Furosemide (10 mg/kg i.p) was used as standard drug. The extract induced diuretic effects and induced electrolytes excretion in a dose-dependent manner when compared with control. The extract (100 and 50 mg/kg) significantly (p&lt;0.01) increased the volume of urine in comparison to control group. Similarly, the excretion of potassium and sodium were also significantly (p&lt;0.05) increased following extract administration. However, there was no significant change in the pH of urine samples of the extract-treated group compared with control. The result of this study thus offers support to the traditional folker use of this plant as a diuretic agent.</p><p> </p>
