Abstract
Local ischemic damage resulting from ovarian torsion is a common cause of decreased follicular activity and infertility. It was aimed to evaluate the effect of granulocyte colony-stimulating factor (G-CSF) protection on in vitro fertilization (IVF) results against experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. The study consisted of 35 adult female Sprague-Dawley albino rats (sham, ischemia, I/R, I + G-CSF, and I/R + G-CSF) randomly assigned to 5 groups, each containing 7 rats. While bilateral adnexal torsion was applied to the ischemia groups for 3 h, detorsion was applied to the reperfusion groups. Intraperitoneal 100 IU/kg G-CSF was administered 30 min prior to ischemia (I + G-CSF) or reperfusion (I/R + G-CSF). After ovulation induction (intraperitoneal 150-300 IU/kg PMSG), the oocytes were collected and IVF was applied. Statistically significant differences were observed between the collected oocyte numbers in I and I + G-CSF, I/R, and I/R + G-CSF groups (P values were P = 0.001 for the I-I + G-SCF groups and P = 0.003 for I/R-IR + G-CSF, respectively). An increase in the number of MII oocytes obtained was observed in the I + G-CSF and I/R + G-CSF groups compared to the I and I/R groups. Grade 1 and grade 2 embryo numbers were statically different between the I/R and I/R + G-CSF groups (P values were P = 0.023 for grade 1 embryos and P = 0.045 for grade 2 embryos, respectively). G-CSF treatment was found to be effective in reducing I- and I/R-induced ovarian damage.

Abstract
OBJECTIVE Dysregulation of local nitric oxide (NO) synthetases occurs during ischemia and reperfusion associated with cardiopulmonary bypass, deep hypothermic circulatory arrest (DHCA), and reperfusion. Rapid fluctuations in local NO occurring in neonates and infants probably contribute to inflammation-induced microglial activation and neuronal degeneration after these procedures, eventually impairing neurodevelopment. We evaluated the anti-inflammatory efficacy of inhaled NO (iNO) in a piglet model emulating conditions during pediatric open-heart surgery with DHCA. METHODS Infant Yorkshire piglets underwent DHCA (18°C) for 30 minutes, followed by reperfusion and rewarming either with or without iNO (20 ppm) in the ventilator at the onset of reperfusion for 3 hours (n = 5 per group, DHCA-iNO and DHCA). Through craniotomy, brains were extracted after perfusion fixation for histology. RESULTS Plasma NO metabolites were elevated 2.5 times baseline data before DHCA by iNO. Fluoro-Jade C staining identified significantly lower number of degenerating neurons in the hippocampus of the DHCA-iNO group (P = .02) compared with the DHCA group. Morphologic analyses of ionized calcium-binding adapter molecule-1 stained microglia, evaluating cell body and dendritic process geometry with Imaris imaging software, revealed subjectively less microglial activation in the hippocampus of pigs receiving iNO. CONCLUSIONS Using DHCA for 30 minutes, consistent with clinical exposure, we noted that iNO reduces neuronal degeneration in the hippocampus. In addition, iNO reduces microglial activation in the hippocampus after DHCA. The data suggest that iNO reduces neuronal degeneration by ameliorating inflammation and may be a practical mode of neuroprotection for infants undergoing DHCA.

Abstract
The area of fertility preservation is constantly developing. To date, the only
noninvestigational and unequivocally accepted methods for fertility preservation
are cryopreservation of embryos and unfertilized oocytes. This article is one of
several in a monogram on fertility preservation. The debate, pros and cons, and
equivocal data on the use of GnRH analogues for fertility preservation are
elaborated by 3 other manuscripts, in this monogram. A repeat of the arguments,
pros and cons of this debatable issue, would be a repetition and redundancy of
what is already included in this monogram. The subject of ovarian
cryopreservation for fertility preservation is also elaborated by several other
authors in this monogram. It is possible that, in the not too far future, the
technologies of in vitro maturation of primordial follicles to metaphase 2
oocytes, and the “artificial ovary,” will turn clinically available. These
technologies may bypass the risk of resuming malignancy by autotransplantation
of cryopreserved-thawed ovarian tissue in leukemia and diseases where malignant
cells may persist in the cryopreserved ovarian tissue. We summarize here the
suggested options for future endeavors in fertility preservation.

Abstract
BACKGROUND Bone marrow stromal cells (BMSCs), as a type of mesenchymal stem cells, and the granulocyte colony-stimulating factor (G-CSF), as a type of growth factor, may recover damaged ovaries. The aim of the present study was to investigate the effects of the coadministration of BMSCs and the G-CSF on damaged ovaries after creating a chemotherapy model with cyclophosphamide (CTX) in rats. METHODS The present study was performed in Semnan, Iran, in the late 2016 and the early 2017. BMSCs were cultured and were confirmed using the CD markers of stromal cells. Forty female Wistar rats were randomly divided into 4 groups. The rats were injected intraperitoneally with CTX for 14 days to induce chemotherapy and ovarian destruction. Then, the BMSCs were injected into bilateral ovaries and the G-CSF was injected intraperitoneally, individually and together. Four weeks later, the number of ovarian follicles using H&E staining, the number of apoptotic granulosa cells using the TUNEL assay, the number of produced oocytes from the ovaries, and the levels of serum E2 and FSH using an ELISA reader were assessed. Statistical analysis was done using one-way ANOVA with SPSS, version 16.0. RESULTS The results showed that the effects of the coadministration of 2×106 BMSCs and 70 µg/kg of the G-CSF were significantly more favorable than those in the control group (P<0.001), the BMSC group (P=0.016), and the G-CSF group (P<0.001) on the recovery of damaged ovaries. CONCLUSION The efficacy of the coadministration of BMSCs and the G-CSF in the recovery of ovaries damaged by chemotherapy was high by comparison with the administration of either of them separately.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein commonly used in the field of medicine to treat neutropenia. Granulocyte colony-stimulating factor has also crucial roles in ameliorating the ischemia/reperfusion (I/R) injury in particular tissues. In this study, we aimed to investigate the protective effect of G-CSF on ovarian damage in experimental ovarian I/R injury. Thirty adult female rats were used. Rats were separated randomly into 5 groups; Group 1: sham group (abdominal wall was opened and closed surgically), Group 2: torsion group with 3-hour ischemia using vascular clips. Group 3: torsion + G-CSF group with 3-hour ischemia 30 minutes after the administration intraperitoneal (i.p.) of 100 µg/kg of G-CSF. Group 4: torsion-detorsion group with 3 hour ischemia and 3 hour reperfusion. Group 5: torsion-detorsion + G-CSF group with 3 hour ischemia followed by 100 µg/kg of G-CSF i.p. administration 30 minutes prior to 3 hour of detorsion/reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde (MDA) was measured biochemically. In comparison with the sham group, both the torsion and torsion-detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage, and leukocyte infiltration (P < .05). When compared group torsion-detorsion + G-CSF to group torsion-detorsion, parameters aforementioned significantly decreased in group torsion-detorsion + G-CSF (P < .05). Granulocyte colony-stimulating factor has also decreased MDA levels notably both in the torsion + G-CSF and torsion-detorsion + G-CSF groups (P < .05, P < .01). Our experimental study suggests that G-CSF can be a novel agent for the treatment of ovarian I/R injury.

Abstract
The aim of the present study was to investigate the protective effect of granulocyte colony-stimulating factor (G-CSF) on acute ischemic cerebral injury, and its mechanism through the impact of G-CSF on early growth response-1 (Egr-1) and vascular endothelial growth factor (VEGF) expressions. Male Sprague-Dawley (SD) rats were divided them into three groups, i.e., the sham, model and G-CSF groups to measure the effect of G-CSF on the volume of cerebral infarction and level of lactate dehydrogenase (LDH) in rats. Hematoxylin and eosin (H&E) staining method was performed for histopathological examination. Reverse transcription-polymerase chain reaction (RT-PCR) and western blot analysis were used to detect the mRNA and protein expressions of Egr-1 and VEGF in different groups. Furthermore, Statistical Product and Service Solutions (SPSS) 17.0 software was applied to detect the differences in the expression of Egr-1 and VEGF between the two groups. Compared with the sham group, we found that the volume of cerebral infarction and LDH content in the model group were significantly elevated. By contrast, in the model group, those indicators in the G-CSF group were obviously decreased. H&E staining results also showed that G-CSF could decrease the necrotic area in cerebral infarction and the incidence of inflammation, and sustain the integrity of the molecular structure. Immunofluorescence staining results revealed that the protein expressions of Egr-1 and VEGF in the model group were all significantly decreased, while those in the G-CSF group were remarkably elevated. RT-PCR and western blot analysis revealed that the mRNA and protein expressions of Egr-1 and VEGF in the model group were decreased obviously, but those in the G-CSF group were elevated significantly, and the differences between the two groups showed statistical significance (P<0.05). G-CSF manifests a significant protective effect on the acute ischemic cerebral injury, which may be realized through its effect on the expressions of Egr-1 and VEGF.

Abstract
OBJECTIVES Ischaemic brain injury is a major complication in patients undergoing surgery for congenital heart disease, with the hippocampus being a particularly vulnerable region. We hypothesized that neuronal injury resulting from cardiopulmonary bypass and associated circulatory arrest is ameliorated by pretreatment with granulocyte colony-stimulating factor (G-CSF), a cytokine and an anti-apoptotic neurotrophic factor. METHODS In a model of ischaemic brain injury, 4 male newborn piglets were anaesthetized and subjected to deep hypothermic circulatory arrest (DHCA) (cooled to 18°C, DHCA maintained for 60 min, rewarmed and recovered for 8-9 h), while 4 animals received G-CSF (34 µg/kg, intravenously) 2 h prior to the DHCA procedure. At the end of each experiment, the animals were perfused with a fixative, the hippocampus was extracted, cryoprotected, cut and the brain sections were immunoprocessed for activated caspase 3, a pro-apoptotic factor. Immunopositive neuronal nuclei were counted in multiple counting boxes (440 × 330 µm) centred on the CA1 or CA3 hippocampal regions and their mean numbers compared between the different treatment groups and regions. RESULTS G-CSF pretreatment resulted in significantly lower counts of caspase 3-positive nuclei per counting box in both the CA1 [52.2 ± 9.3 (SD) vs 61.6 ± 8.4, P < 0.001] and CA3 (41.2 ± 6.9 vs 60.4 ± 16.4, P < 0.00002) regions of the hippocampus as compared to DHCA groups. The effects of G-CSF were significant for pyramidal cells of both regions and for interneurons in the CA3 region. CONCLUSIONS In an animal model of ischaemic brain injury, G-CSF reduces neuronal injury in the hippocampus, thus potentially having beneficial effect on neurologic outcomes.

Abstract
Mounting evidence suggests that neurological injury occurs after deep hypothermic circulatory arrest (DHCA), a protocol widely used in surgery for congenital heart diseases and aortic repair. Neuregulin 1 (NRG1), a neurotrophic factor highly expressed in the central nervous system, is crucial for neuronal survival. However, whether NRG1 is protective against apoptosis induced by DHCA is still unclear, as are the putative mechanisms involved. In this study, exogenous human NRG1 pretreatment (2.5 and 3.75 ng/kg, intracarotid injection) significantly inhibited neuronal apoptosis in DHCA-treated male rats, and notably, endogenous NRG1 expression was also increased. Bcl-2, as well as phosphorylated phosphatidylinositol-3-kinase, Akt, and cAMP-response element binding protein, were all increased, resulting in phosphorylation and subsequent activation of the ErbB4 receptor. Finally, expression of the apoptosis-related protein cleaved-caspase-3 was decreased, resulting in the inhibition of neuronal apoptosis induced by DHCA. Thus, our data indicate that NRG1 treatment inhibited DHCA-induced neuronal apoptosis by activating ErbB4 signaling, providing a potential therapeutic pathway for the prevention of neurological injury induced by DHCA.

Abstract
Objective Infants are more vulnerable to kidney injuries induced by inflammatory response syndrome and ischemia-reperfusion injury following cardiopulmonary bypass especially with prolonged hypothermic low-flow (HLF). This study aims to evaluate the protective role of ulinastatin, an anti-inflammatory agent, against acute kidney injuries in infant piglets model undergoing surgery on HLF cardiopulmonary bypass. Methods Eighteen general-type infant piglets were randomly separated into the ulinastatin group (Group U, n = 6), the control group (Group C, n = 6), and the sham operation group (Group S, n = 6), and anaesthetized. The groups U and C received following experimental procedure: median thoracotomy, routine CPB and HLF, and finally weaned from CPB. The group S only underwent sham median thoracotomy. Ulinastatin at a dose of 5,000 units/kg body weight and a certain volume of saline were administrated to animals of the groups U and C at the beginning of CPB and at aortic declamping, respectively. Venous blood samples were collected at 3 different time points: after anesthesia induction in all experimental groups, 5 minutes, and 120 minutes after CPB in the Groups U and C. Markers for inflammation and acute kidney injury were tested in the collected plasma. N-acetyl-β-D-glucosaminidase (NAG) from urine, markers of oxidative stress injury and TUNEL-positive cells in kidney tissues were also detected. Results The expressions of plasma inflammatory markers and acute kidney injury markers increased both in Group U and Group C at 5 min and 120 min after CPB. Also, numbers of TUNEL-positive cells and oxidative stress markers in kidney rose in both groups. At the time point of 120-min after CPB, compared with the Group C, some plasma inflammatory and acute kidney injury markers as well as TUNEL-positive cells and oxidative stress markers in kidney were significantly reduced in the Group U. Histologic analyses showed that HLF promoted acute tubular necrosis and dilatation. Conclusions HLF cardiopulmonary bypass surgery could intensify systemic inflammatory responses and oxidative stress on infant piglets, thus causing acute kidney injury. Ulinastatin might reduce such inflammatory response and oxidative stress and the extent of kidney injury.

Abstract
BACKGROUND AND AIMS The objective of this study was to elucidate whether a Western diet was associated with nonalcoholic steatohepatitis (NASH), and the relationship between NASH, autophagy and endoplasmic reticulum (ER) stress. METHODS Four-month-old Lee-Sung minipigs were randomly assigned to two groups: control diet (C) and Western diet (W), for a 5-month experimental period. RESULTS Feeding a Western diet produced a body composition with more fat, less lean and a greater liver weight. Compared with C pigs, W pigs also exhibited an elevated level of plasma insulin and free fatty acid. The W pigs displayed glucose intolerance, lower circulation antioxidant capacity and greater hepatic oxidative stress. Furthermore, pig fed the W diets had increased collagen accumulation in the liver and elevated systemic inflammation [tumor necrosis factor α and interleukin (IL)-6]. Compared with C pigs, W pigs had higher hepatic ER stress-related protein expression of GRP94, CHOP and caspase-12. The W pigs also had greater hepatic autophagy-related protein expression of p62 and LC3II. In an obesity antibody array analysis, W pigs had higher type 2 diabetes mellitus- (insulin-like growth factor 1, osteoprotegerin and resistin), atherosclerosis- (vascular endothelial growth factor, platelet-derived growth factor-AA and plasminogen activator inhibitor-I) and inflammation- [IL-1, macrophage-stimulating protein alpha, X-linked ectodermal dysplasia receptor and serum amyloid A (SAA)] related protein expressions. In addition, W pigs had greater plasma SAA concentration than C pigs and plasma SAA level was highly associated with IL-6. CONCLUSIONS We successfully established a NASH pig model, and our findings suggested an association of NASH with ER stress and autophagy. The SAA has potential as a novel plasma biomarker for nonalcoholic fatty liver disease pigs.

Abstract
Cardiac abnormalities are the most common birth defects. Derangement of circulatory flow affects many vital organs; without proper supply of oxygenated blood, the brain is particularly vulnerable. Although surgical interventions have greatly reduced mortality rates, patients often suffer an array of neurological deficits throughout life. Neuroimaging provides a macroscopic assessment of brain injury and has shown that white matter (WM) is at risk. Oligodendrocytes and myelinated axons have been identified as major targets of WM injury, but still little is known about how congenital heart anomalies affect the brain at the cellular level. Further integration of animal model studies and clinical research will define novel therapeutic targets and new standards of care to prevent developmental delay associated with cardiac abnormalities.

Granulocyte colony stimulating factor reduces brain injury in a cardiopulmonary bypass-circulatory arrest model of ischemia in a newborn piglet. Neurochem Res 2014; 39:2085-92. [PMID: 25082120 PMCID: PMC4265391 DOI: 10.1007/s11064-014-1399-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2014] [Revised: 06/09/2014] [Accepted: 07/23/2014] [Indexed: 11/30/2022]
Abstract
Ischemic brain injury continues to be of major concern in patients undergoing cardiopulmonary bypass (CPB) surgery for congenital heart disease. Striatum and hippocampus are particularly vulnerable to injury during these processes. Our hypothesis is that the neuronal injury resulting from CPB and the associated circulatory arrest can be at least partly ameliorated by pre-treatment with granulocyte colony stimulating factor (G-CSF). Fourteen male newborn piglets were assigned to three groups: deep hypothermic circulatory arrest (DHCA), DHCA with G-CSF, and sham-operated. The first two groups were placed on CPB, cooled to 18 °C, subjected to 60 min of DHCA, re-warmed and recovered for 8-9 h. At the end of experiment, the brains were perfused, fixed and cut into 10 µm transverse sections. Apoptotic cells were visualized by in situ DNA fragmentation assay (TUNEL), with the density of injured cells expressed as a mean number ± SD per mm(2). The number of injured cells in the striatum and CA1 and CA3 regions of the hippocampus increased significantly following DHCA. In the striatum, the increase was from 0.46 ± 0.37 to 3.67 ± 1.57 (p = 0.002); in the CA1, from 0.11 ± 0.19 to 5.16 ± 1.57 (p = 0.001), and in the CA3, from 0.28 ± 0.25 to 2.98 ± 1.82 (p = 0.040). Injection of G-CSF prior to bypass significantly reduced the number of injured cells in the striatum and CA1 region, by 51 and 37 %, respectively. In the CA3 region, injured cell density did not differ between the G-CSF and control group. In a model of hypoxic brain insult associated with CPB, G-CSF significantly reduces neuronal injury in brain regions important for cognitive functions, suggesting it can significantly improve neurological outcomes from procedures requiring DHCA.

Granulocyte-colony stimulating factor decreases the extent of ovarian damage caused by cisplatin in an experimental rat model. J Gynecol Oncol 2014; 25:328-33.

Abstract
Objective To investigate whether granulocyte-colony stimulating factor (G-CSF) can decrease the extent of ovarian follicle loss caused by cisplatin treatment. Methods Twenty-one adult female Sprague-Dawley rats were used. Fourteen rats were administered 2 mg/kg/day cisplatin by intraperitoneal injection twice per week for five weeks (total of 20 mg/kg). Half of the rats (n=7) were treated with 1 mL/kg/day physiological saline, and the other half (n=7) were treated with 100 µg/kg/day G-CSF. The remaining rats (n=7, control group) received no therapy. The animals were then euthanized, and both ovaries were obtained from all animals, fixed in 10% formalin, and stored at 4℃ for paraffin sectioning. Blood samples were collected by cardiac puncture and stored at -30℃ for hormone assays. Results All follicle counts (primordial, primary, secondary, and tertiary) and serum anti-Müllerian hormone levels were significantly increased in the cisplatin+G-CSF group compared to the cisplatin+physiological saline group. Conclusion G-CSF was beneficial in decreasing the severity of follicle loss in an experimental rat model of cisplatin chemotherapy.
