Repairing Effect

To explore the repairing effect of platelet-rich plasma (PRP) on tendon (AT) healing, and provide evidence for PRP therapy to treat tendon-related diseases, 32 New Zealand white rabbits were selected to construct tendinopathy animal model. Leukocyte-rich Platelet-Rich Fibrin (Lr-PRP) and Leukocyte-poor Platelet-Rich Fibrin (Lp-PRP) were prepared, whose biological effects on tendon stem cells (TSCs) were explored. Rabbits were divided into control group, low, medium, and high dose groups regrading concentration of Lp-PRP. The number of fibroblasts, collagen fiber content, tubuloglomerular feedback-β1 (TGF-β1) expression, and biomechanical properties were compared at 15 and 30 days after operation. The results showed that Collagen-III (CoI-III) protein expression levels, interleukin-β (IL-β), and interleukin-6 (IL-6) levels in the Lp-PRP group were significantly higher than Lr-PRP group (P < 0.05). Fibroblasts and collagen fibers in group II and III were significantly higher versus group C 15 and 30 days after operation (P < 0.05). Fibroblasts and of collagen fibers in group III were significantly higher versus group II (P < 0.05). Expression of TGF-β1 in groups II and III was significantly higher than that in group C 15 days after operation (P < 0.05). Tensile load of AT repair site in group III was significantly higher than group C 30 days after operation (P < 0.05). Platelet plasma concentration had a certain repair effect on tendon injury and can effectively improve the quality of healing. In addition, Lp-PRP was better than Lr-PRP in tissue healing. When the concentration of Lp-PRP was 100%, the repair effect was the best.

Background: Nevertheless, several studies of LMWH in acute ischemic stroke have been neutral with regard to their primary outcomes, and it remains unclear whether these drugs should be used routinely or not. Our present trial endeavors to study the efficacy of LMWH (low and high dose dalteparin) in patients with progressive ischemic stroke in terms of morbidity and mortality as compared to control group and to compare it with AS+CLOP, with respect to these event rates, at the end of treatment.Methods: Our study was performed on 38 patients of acute ischemic stroke admitted to LLR and associated Hospitals, G. S. V. M. Medical College, Kanpur and who were assigned randomly to any of the four treatment groups (0.4ml dalteparin, 0.8ml of dalteparin, O ml of placebo and aspirin +clopidogrel 150+75 mg). The standard error of proportion method and Chi square test was applied.Results: 70% of patients in group I, 62.5% in Group II and 60% Group III presented with stroke in evolution at presentation as compared to only 30% in the placebo group. 75% of patients in group I, 66.66% in group II, 50% in Group III and 33.34% in group IV had a complete recovery. 25% of patients in Group-I, 33.34% in Group-II, 50% in Group III and 66.66% in Group-IV had an incomplete recovery.Conclusions: There is no significant reduction in the mortality and morbidity amongst LMWH groups at the end of treatment and end of trial as compared to the AS+CLOP, or placebo group or even amongst the low and high dose LMWH groups.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Introduction: Anemia of prematurity (AOP) is a common problem of very low birth weight babies. Blood transfusion is a necessity when it occurs in moderate to severe form putting the child in to the risk of transfusion related complications. Erythropoietin, a potent stimulator of hemopoesis is available in breast milk in good amount and absorbed intact under physiologic condition. In this background oral recombinant human erythropoietin (rhEPO) can be a useful alternative to its subcutaneous administration in prevention of AOP.Objective: To evaluate the efficacy of oral rhEPO in the prevention of AOP in very low birth weight (VLBW) neonates.Methods: This randomized controlled study conducted in the NICU of BSMMU over one year. Total 60 preterm (<34 weeks)VLBW (<1500g) infants were enrolled and randomly divided into Control (group-I), Oral (group-II) and Subcutaneous (group III). Experimental groups (group-II & group-III) received rhEPO 400 IU/Kg, 3 times weekly in oral and subcutaneous (S/C) route respectively and continued for 2 weeks (Total 6 doses). Therapy was initiated 14 days after birth when the baby achieved oral feeding of at least 50 ml/kg/day of breast milk. All infants received oral iron and folic acid supplementation up to 12 weeks of postnatal age. Transfusion data were recorded. Anthropometric and hematological assessments were done at 2, 4, 6 and 12 weeks of age.Results: Baseline clinical characteristics and hematological values were almost similar in all groups. Mean hemoglobin were 11.34±0.68gm/dl, 11.88±0.54gm/dl& 12.12±1.32 gm/dl, the mean hematocrit were 34.11±2.03%, 35.66±1.65% & 36.38±3.97% and the mean reticulocyte were 7.56±2.48%, 9.85±1.50% & 9.22±3.11% in the control, oral and subcutaneous group respectively and the differences are statistically significant (p<0.05).Weight gain was higher in the intervention group at 6 and 12 weeks follow up than the control group(p<0.05).Only 2 (5.25%) infants, one in each of the intervention groups required blood transfusion, compared to 6 (31.5%) infants in control group (p<0.01).Conclusion: Oral EPO is as good as subcutaneous use of EPO in stimulating erythropoesis, maintaining HCT and Hb at high level and is safe in preterm baby.Bangladesh J Child Health 2017; VOL 41 (2) :101-109

It has been shown that guineapigs can be effectively protected against re-infection by the subcutaneous inoculation of embryonated Ascaris eggs (Soulsby, 1957). The purpose of this communication is to report a successful attempt to immunize guineapigs against a lethal oral challenge dose of eggs by the intravenous inoculation of third stage larvae of A. suum.Three groups, each containing nine guineapigs, were infected with Ascaris as follows: Group I was given 10,000 eggs by mouth. Group II Was inoculated intravenously with 2,000 third stage Ascaris larvae which had been obtained from the lungs of other guineapigs on the sixth day of infection. Both groups were challenged at the same time with 250,000 eggs by mouth, along with a control group (Group III) which had no previous infection. The guineapigs in Group I were re-infected after 18 days and those in Group II after 12 days.

Background: Nephrotoxicity is characterized by raised serum urea and creatinine levels and kidneys being one of the primary organs of drug concentration and excretion are vulnerable to many widely used marketed drugs, including anti-cancer drugs, antibiotics, immunosuppressants, and radio contrast agents, are nephrotoxic. Aim: To determine the nephroprotective effect of ethanolic extract of Carica papaya seeds in Aminoglycoside induced acute nephrotoxicity. Study design: Quasi Experimental study. Methodology: Thirty Sprague Dawley rats were sub divided into 3 groups i.e., I, II and III with 10 rats in each group. Group II and III were administered Aminoglycoside drug; Gentamycin in 80 mg/kg) via intraperitoneal route once daily for 5 consecutive days to induce acute nephrotoxicity. At day 6, nephrotoxicity was confirmed by measuring serum urea and creatinine. Ethanolic extract of Carica papaya seeds (1000 mg/kg) was started once daily through oral route in group III for 5 consecutive days to see the nephroprotective effects of seed extract after causing acute kidney injury. All animals were given standard diet pellets manufactured at NIH. Results: Mean serum urea and creatinine for Group I (Control Group) at day 0 were 24.90 mg/dL ± 1.633 and .750 mg/dL ± .0619 respectively. Mean serum urea and creatinine for Group II (Disease Control Group) was 81.00 mg/dL ± 1.247 and 1.980mg/dL ± .0467 at day 6th. This suggested induction of nephrotoxicity by Gentamycin. Mean serum urea and creatinine for Group III (Ethanolic Extract Treated Group) at 11 day was 72.40mg/dL± .991 and 1.680 mg/dL± .0467 after 5 days treatment with ethanolic extract of Carica papaya seeds. Conclusion: We concluded that ethanolic extract of Carica papaya seeds has significant nephroprotective effects on Aminoglycoside induced acute nephrotoxicity in rats.

Abstract Background The duration of birth is an important factor influencing the survival of piglets and the health of sows. A prolonged parturition is usually treated with oxytocin, even though several undesirable side effects are described. Therefore, the aim of this study was to evaluate the safety and efficacy of Prostaglandin E2 (PGE2) of different concentrations as an intravaginal applied gel in sows. MethodsTwelve sows were randomly allocated to one of four treatment groups: Group I (control group) application of placebo gel; Group II application of 2.0 mg PGE2; Group III application of 1.0 mg PGE2; Group IV application of 0.5 mg PGE2. The gel was administered intravaginal after the birth of the fourth piglet. Total duration of birth (time between first piglet and last placenta), piglet interval and placenta expulsion duration (time between first and last placenta) were recorded, and each piglet was scored for meconium staining and vitality. Furthermore, stillborn piglets were categorized into ante-partum and intra-partum deaths. Results Although no significant differences between the groups were detected, a beneficial tendency in several parameters was observed in group III. The duration of birth was 284 min (average of 14.3 piglets per litter), whereas in all other groups it was more than 400 min (average of 18.0 piglets per litter). The piglet interval was 10.1 min in group II compared to 10.2 min in group III, 16 min in group IV and 21.4 min in group I. In group III the placenta expulsion duration was 119 min in contrast to the other groups with more than 266 min. Severe meconium staining in more than 10% of piglets was observed in group II and IV. Moreover, piglets of group II showed oedematous and haemorrhagic umbilical cords, lethargy and anoxia, and intra-partum deaths were recorded. Conclusion Although the sample size is limited in this study, it is assumed that an application of 1mg PGE2 intra-partum instead of lower or higher dosages has the most beneficial effects on the birth process in sows and on the vitality of piglets. Further investigation is necessary to confirm the positive effect of PGE2 in daily practise.

Abstract Background Tumours in mammary glands represent the most common neoplasia in bitches, as in humans. This high incidence results in part from the stimulation of sex hormones on these glands. Among mammary tumours, inflammatory carcinoma is the most aggressive, presenting a poor prognosis to surgical treatment and chemotherapy. One of the most widely used chemotherapy drugs for breast cancer treatment is doxorubicin (DOXO). Alternative therapies have been introduced in order to assist in these treatments; studies on treatments using stem cells have emerged, since they have anti-inflammatory and immunomodulatory properties. The aim of this study was to evaluate the effects of DOXO and canine amniotic membrane stem cells (AMCs) on the triple-negative canine inflammatory mammary carcinoma cell line IPC-366. Methods Four experimental groups were analysed: a control group without treatment; Group I with DOXO, Group II with AMC and Group III with an association of DOXO and AMCs. We performed the MTT assay with DOXO in order to select the best concentration for the experiments. The growth curve was performed with all groups (I-III) in order to verify the potential of treatments to reduce the growth of IPC-366. For the cell cycle, all groups (I-III) were tested using propidium iodide. While in the flow cytometry, antibodies to progesterone receptor (PR), estrogen receptor (ER), PCNA, VEGF, IL-10 and TGF-β1 were used. For steroidogenic pathway hormones, an ELISA assay was performed. Results The results showed that cells treated with 10 µg/mL DOXO showed a 71.64% reduction in cellular growth after 72 h of treatment. Reductions in the expression of VEGF and PCNA-3 were observed by flow cytometry in all treatments when compared to the control. The intracellular levels of ERs were also significantly increased in Group III (4.67% vs. 27.1%). Regarding to the levels of steroid hormones, significant increases in the levels of estradiol (E2) and estrone sulphate (S04E1) were observed in Groups I and III. On the other hand, Group II did not show differences in steroid hormone levels in relation to the control. We conclude that the association of DOXO with AMCs (Group III) promoted a reduction in cell growth and in the expression of proteins related to proliferation and angiogenesis in IPC-366 triple-negative cells. Conclusions This treatment promoted ER positive expression, suggesting that the accumulated oestrogen conducted these cells to a synergistic state, rendering these tumour cells responsive to ERs and susceptible to new hormonal cancer therapies.

Objective: The purpose of this study was to compare the effect of famotidine versus omeprazole on the efficacy of calcium carbonate as a phosphate binder in the hemodialysis patient.Methods: From February 2014 to June 2014 a total number of 64 patients of both sexes were recruited from the department of renal dialysis, Tanta University Hospital, Egypt. Patients categorized into 3 groups. Group I (control group) consisted of 20 Patients (10) females and (10) males take calcium carbonate (caco3) (2.5–4 g/d) only, Group II consisted of 21 Patients (13) females and (8) males take the same dose of caco3 with famotidine 10 mg/d and Group III consisted of 23 Patients (8) females and (15) male take the same dose caco3 with omeprazole 20 mg/d.Results: All data are expressed as the mean±SD. Group II showed a significant increase (p<0.05) in serum phosphorus at 3rd mo with significant decreased (p<0.05) in serum calcium comparing with pre-treatment. Group III showed no significant change (p>0.05) in serum calcium, phosphorus and parathyroid hormone (PTH) comparing with pre-treatment. Both groups (II and III) showed a significant decrease in alkaline phosphatase (ALP) (p<0.05).Conclusion: Co-administration of famotidine with calcium carbonate aggravates hyperphosphatemia and this may increase the incidence of complications. The efficacy of calcium carbonate as a phosphate binder was not affected by co-administration of omeprazole.
