Hypothalamic amenorrhea and energy restriction during puberty affect peak bone mass accrual. One hypothesis suggests energy restriction alters hypothalamic function resulting in suppressed estradiol levels leading to bone loss. However, both positive and negative results have been reported regarding energy restriction and bone strength. Therefore, the purpose of this study was to investigate energy restriction and hypothalamic suppression during pubertal onset on bone mechanical strength and the osteogenic capacity of bone marrow-derived cells in two models: female rats treated with gonadotropin releasing hormone antagonists (GnRH-a) or 30% energy restriction. At 23 days of age, female Sprague Dawley rats were assigned to three groups: control group (C, n = 10), GnRH-a group (n = 10), and Energy Restriction (ER, n = 12) group. GnRH-a animals received daily injections for 27 days. The animals in the ER group received 70% of the control animals' intake. After sacrifice (50 days of age), body weight, uterine and muscle weights were measured. Bone marrow-derived stromal cells were cultured and assayed for proliferation and differentiation into osteoblasts. Outcome measures included bone strength, bone histomorphometry and architecture, serum IGF-1 and osteocalcin. GnRH-a suppressed uterine weight, decreased osteoblast proliferation, bone strength, trabecular bone volume and architecture compared to control. Elevated serum IGF-1 and osteocalcin levels and body weight were found. The ER model had an increase in osteoblast proliferation compared to the GnRH-a group, similar bone strength relative to body weight and increased trabecular bone volume in the lumbar spine compared to control. The ER animals were smaller but had developed bone strength sufficient for their size. In contrast, suppressed estradiol via hypothalamic suppression resulted in bone strength deficits and trabecular bone volume loss. In summary, our results support the hypothesis that during periods of nutritional stress the increased vertebral bone volume may be an adaptive mechanism to store mineral which differs from suppressed estradiol resulting from hypothalamic suppression.  相似文献

Background  Increased intra-abdominal pressure (IAP) (pneumoperitoneum) during laparoscopic surgery may result in adverse effects on kidney function. The mechanisms underlying this phenomenon have not been fully determined. Objective  The present study was designed to: (1) investigate the effects of incremental increases in IAP on renal function in normal rats and (2) evaluate whether the nitric oxide (NO) system is involved in renal dysfunction characterizing pneumoperitoneum. Methods  Male rats were organized into two groups. The first group was subjected to IAP of 0 (baseline), 7 or 14 mmHg, over 1 h for each pressure, followed by a deflation period of 60 min (recovery). Two additional groups were pretreated with: (1) non-depressor dose of nitroglycerine (NTG) and (2) nitro-L-arginine-methylester (L-NAME), an NO synthase inhibitor, before applying 14 mmHg for 1 h. Urine flow rate (V), Na+ excretion (UNaV), glomerular filtration rate (GFR), renal plasma flow (RPF), and blood pressure were determined throughout the experiments. Results  There were no significant changes in V, UNaV, GFR, and RPF during 7 mmHg insufflation. However, significant reductions in these parameters were observed during 14 mmHg: V from 8.49 ± 0.92 to 6.12 ± 0.54 μl/min, UNaV from 1.29 ± 0.28 to 0.39 ± 0.09 μEq/min, and FENa from 0.37 ± 0.11 to 0.27 ± 0.04%. These alterations in excretory functions were associated with a considerable decline in GFR from 1.85 ± 0.09 to 0.88 ± 0.09 ml/min, p < 0.05, (−46.3 ± 5.2% from baseline) and RPF from 8.66 ± 0.62 to 4.33 ± 0.49 ml/min, p < 0.05, (−51.93 ± 5.24% from baseline), without a significant change in mean arterial blood pressure (MAP). When the animals were pretreated with NTG, the adverse effects of pneumoperitoneum on V, UNaV, GFR, and RPF were substantially improved, suggesting that NO system plays a beneficial counter-regulatory role during laparoscopy. In line with this notion, pretreatment with L-NAME remarkably aggravated pneumoperitoneum-induced renal hypoperfusion and dysfunction. Conclusion  Decreased renal perfusion and function are induced by IAP pressure of 14 mmHg. These adverse effects are probably related to interference with the NO system, and could be partially ameliorated by pretreatment with NTG. Bishara Bishara and Tony Karram contributed equally.  相似文献

Background

Caloric restriction (CR) increases both average and maximum lifespan, retards physiological signs of ageing, and delays the onset of several diseases and may mediate neuropathic pain. Neuropathic pain seriously affects the quality of life of patients. In this study, we investigated whether CR exerts anti-nociceptive effects on neuropathic pain, and probed its potential mechanisms.

Methods

Adult rats were divided into two dietary groups: an ad libitum (AL)-fed group and a CR group, which was provided with 60% of the food intake of AL rats for 6 weeks. The effects of 6-week CR on pain behaviour and neuro-inflammation induced by chronic constriction injury of the sciatic nerve were evaluated.

Results

Rats subjected to a CR diet had reduced hypersensitivity to mechanical and thermal stimuli after nerve-constriction injury. CR increased the silent information regulator 1 (SIRT1) expression, and suppressed the nerve-constriction-induced production of mitochondrial-derived reactive oxygen species and activation of nuclear factor kappa B accompanied by suppression of mature interleukin-1β production in the ipsilateral spinal cord dorsal horn. The inhibition of SIRT1 reversed the effects of caloric restriction on pain behaviours. Moreover, CR decreased the phosphorylation of N-methyl-d-aspartate receptor subunits and the mitogen-activated protein kinase family, decreased the sensory neurone excitability, and inhibited the nerve-constriction-induced glial-cell activation.

Conclusions

These results suggest that the effects of CR on pain behaviours in a rat model of nerve injury are via inhibition of excessive neuro-inflammation induced by the injury. CR may be of benefit in patients with neuropathic pain.  相似文献

The present review summarizes recent studies describing the role of renal sympathetic innervation in the regulation of renal function during development. The afferent renal innervation appears early during fetal life and probably precedes the development of efferent renal nerves. There is suggestive evidence that renal nerves are required for the proper development of the kidney and that neurotrophic growth factors play an important role in renal embryogenesis and in renal tubular differentiation. Renal sympathetic innervation modulates renal hemodynamics early during development. Renal nerve stimulation during -adrenoceptor blockade produces renal vasodilation in fetal and newborn animals but not in adults. Unlike the effect of renal nerves on fetal renal hemodynamics which is observed in the young fetus, the role of renal sympathetic nerves in modulating fluid and electrolyte homeostasis seems to develop during late gestation. Recent studies have also shown that renal nerves play an important role in regulating renin secretion during the transition from fetal to newborn life. For example, renal denervation during fetal life suppressed the physiological rise in plasma renin activity associated with delivery and decreased renal renin mRNA levels after birth. Taken together, these studies suggest that renal nerves influence fetal renal development and that the influence of renal sympathetic innervation on renal hemodynamics and function changes with maturation.  相似文献

BackgroundObesity is associated with albuminuria and impaired renal function. We previously reported on 38 nondiabetics with improved albuminuria after Roux-en-Y gastric bypass (RYGB).MethodsOur objectives were to evaluate changes in renal function, urinary albumin-to-creatinine ratio (UACR), and glomerular filtration rate (GFR) in a larger cohort of patients with normal or mildly impaired renal function, undergoing RYGB or sleeve gastrectomy at 1 year postop. This was a retrospective study. Inclusions: patients with preoperative and 1 year postoperative serum and urine albumin and creatinine and weight (kg). Exclusions: preop chronic kidney disease (CKD)≥Stage 3 or macroalbuminuria (UACR≥300 mg/g). Primary outcomes: changes in UACR and estimated GFR (eGFR) at 1 year. The setting was in a public hospital in New York City, 2004–2011.Results158 patients met inclusion criteria; 91.8% female; mean age 40.8 years; 84.2% white Hispanic, 14.6 % black. Hypertension was present in 43.0%, diabetes mellitus in 28.5%. UACR was 21.5±3.2 mg/g, decreasing to 10.2±1.2 mg/g at 1 year (P<.0001). Microalbuminuria was present in 22/158 patients (14%) preop, resolving in 82% at 1 year; pre- versus 1 year postop eGFR, 97.5±2.2 versus 87.1±2.0 mL/min (P<.0001). Hyperfiltration was present in 8.2% preop, decreasing to 4.4% 1 year postop.ConclusionIn this mainly female minority population, UACR decreased within the normal range, while eGFR decreased from normal to the range for Stage 2 CKD at 1 year postop. Microalbuminuria resolved in most affected and hyperfiltration resolved in nearly half of those affected. This study is limited by its retrospective nature. Prospective studies should be performed.  相似文献

In the last few years, renal artery stenting has gradually evolved into one of the most important therapeutic modalities in the management of atherosclerotic renovascular disease. Stenting is nowadays preferred by a steadily increasing number of physicians, not only because of its significant contribution to blood pressure control, but also because of its documented ability to maintain, and even improve, renal function. At the same time, procedure-related morbidity and mortality rates are extremely low, while recurrent stenosis rates have been repeatedly reported to be␣minimal. Percutaneous transluminal renal angioplasty (PTRA) and stenting are nowadays considered by many physicians to be the treatment of choice for atherosclerotic renovascular disease.  相似文献

The safety of cysteamine after renal transplantation and during pregnancy is an important issue, since girls with cystinosis are in better health on cysteamine therapy and thus more likely to become pregnant. In the first study, cysteamine was given to pregnant rats on days 6.5–18.5 post conception in oral doses of 0, 37.5, 75, 100, and 150 mg/kg per day. The dams were sacrificed on day 20.5, the fetal kidneys removed and prepared for histological examination. In the second study, cysteamine was given to dams on days 6.5–19.5 post conception in oral doses of 0, 37.5, 50, and 75 mg/kg per day. Dams were allowed to give birth naturally and pups were given cysteamine on days 4–21 to yield the same oral doses of cysteamine given to the dam. Renal function was evaluated on day 35. Histological examination of fetal kidneys revealed no changes even in kidneys from fetuses with growth retardation and malformations. Furthermore, there were no alterations in renal function in offspring on day 35. These findings demonstrate that cysteamine therapy does not affect renal development in the rat. Further investigations will be required to prove whether cysteamine therapy has the potential to affect renal development in the human.

Understanding renal maturation and growth is essential before adequate interpretation of radionuclide renal studies can be done. The expectation that an immature kidney draining into a dilated renal pelvis will show good washout on a diuretic renogram within 20 or 40 min is unreasonable. A physiological explanation for this is given.  相似文献

Background The suppressive effect of dietary protein restriction on the progression of diabetic nephropathy remains controversial. We investigated the effects of protein and energy restrictions on both albuminuria and morphology using diabetic-prone Otsuka Long-Evans Tokushima fatty (OLETF) rats. Methods In this study, male OLETF rats were divided into two groups according to their energy intake. They were then further divided into three subgroups based on their amount of dietary protein, which ranged between 10% and 30% of their total intake. Urinary albumin excretion (UAE) was used as a marker of renal impairment, and body weight fasting (F) and postchallenge (P), blood glucose (BG) levels, and systolic blood pressure (SBP) were all measured during various experimental periods up to 28 weeks of age. Results The OLETF rats fed with the high-calorie diet started to gain weight at 12 weeks, and their FBG and PBG were elevated at 22 weeks, while SBP did not differ between the two groups. In addition, UAE increased significantly in the rats fed with the high-calorie diet. However, the increasing rates of UAE with age were higher in the rats with a higher protein diet within the same energy groups. UAE correlated well with the amounts of dietary energy and protein at 16 and 28 weeks of age, while it correlated with both the FBG and PBG at only 28 weeks of age. A linear regression analysis, using the data obtained at 28 weeks, showed that the amount of protein intake and FBG explained 63.4% and 23.9% of the variation in UAE, respectively. Histological studies revealed that protein and energy restriction markedly reduced the sclerotic changes of the glomeruli. Conclusion Dietary protein restriction starting very early in the life of OLETF rats, in combination with energy restriction, clearly suppressed UAE and the typical morphological changes that otherwise occurred at around 16 weeks of age. This method also seemed to be more effective than energy restriction alone in slowing down any increase in UAE. The influence of BG levels on UAE was lower at an early age, while it became an increasingly important factor at later ages in the experimental rat model.  相似文献

Non-allogeneic factors such as increased nephron “workload” may contribute to chronic renal allograft rejection. Reducing dietary protein from 20 % to 8 % was tested in a model of chronic rejection: Dark Agouti kidney to Albino Surgery recipient, “tolerised” by previous donor blood transfusions. Survival, weight gain, serum creatinine concentration and creatinine clearance were similar for both groups at all times. Urinary protein was significantly (P < 0.05) lower in the low-protein (LP) group 1 month after transplantation. After 3 and 6 months, both groups demonstrated mild chronic rejection. After 6 months, tubular atrophy was significantly (P < 0.05) less in the LP group and interstitial fibrosis was marginally reduced. Glomerular hypertrophy, glomerular sclerosis, tubular dilatation, leucocyte infiltration, adhesion molecule expression and TGF-β 1 mRNA expression were similarly increased in both groups. Thus, reducing dietary protein to 8 % lowered urinary protein, but did not significantly affect the development of chronic rejection in renal allografts beyond affording a degree of protection from tubulointerstitial damage.

Purpose. The use of continuous epidural anesthesia in patients with chronic renal failure is rare and controversial. In this study, we compared the effects of epidural versus general anesthesia on early postoperative renal function in patients who underwent renal transplantation surgery. Methods. Sixty-eight adult patients were prospectively randomized to two groups. Group 1 (n-37) received epidural anesthesia with bupivacaine and fentanyl, and group 2 (n-31) received general anesthesia with nitrous oxide and isoflurane. The patients' renal function was compared both with qualitative scintigraphic analysis (kidney perfusion, concentration, and excretion capabilities) and biochemically [serum sodium, potassium, creatinine, and blood urea nitrogen) (BUN)] within the first postoperative week. Results. Patient demographics were similar in the two groups, and the scintigraphic and biochemical evaluations were also comparable. The time of the first appearance of Tc-99m diethylene triamine pentaacetic acid (DTPA) was within normal limits in 75.7% of patients in group 1 and 61.3% of those in group 2. The number of patients with normal peak/background activity and 20 min/peak activity were 15 (40.5%) and 19 (51.4%), respectively, in group 1, and 12 (38.7%) and 15 (48.4%) in group 2 (P > 0.05 for both). The levels of serum creatinine and urea in both groups decreased within days postsurgery compared with preoperative levels (P < 0.05), but the changes were similar in the two groups (P > 0.05). A similar number of patients in both groups were treated for acute rejection (P > 0.05). Conclusion. Our results demonstrate the safe use of both anesthetic techniques in renal transplantation surgery. Received: December 25, 2000 / Accepted: November 5, 2001  相似文献
