Fenofibrate is a drug that has been suggested to inhibit weight gain by increasing the catabolism of fatty acid in the hepatic mitochondria. We hypothesized that fenofibrate induces an increase in energy expenditure in the hepatic mitochondria, which results in the reduction of adipose tissue. In this study we measured hepatic uncoupling protein (UCP)-2, -3, core temperatures and abdominal fat composition with MRI in Otsuka Long-Evans Tokushima Fatty rats. The fenofibrate group (n=7) was fed fenofibrate (320 mg/kg) mixed chow. The control group (n=7) was fed chow only. The body weight (531.6+/-7.6 g) of the fenofibrate group was significantly lower than that (744.3+/-14.9 g) of the control group (p<0.005). The areas of visceral and subcutaneous fat in the fenofibrate group (11.0+/-0.9 cm2, 4.2+/-0.3 cm2) were significantly less than those in the control group (21.0+/-0.7 cm2, 7.4+/-0.4 cm2) (p=0.046, respectively). The esophageal and rectal temperatures of the fenofibrate group (37.7+/-0.1 degrees C, 33.1+/-0.2 degrees C) were significantly higher than those of the control group (37.3+/-0.1 degrees C, 32.2+/-0.1 degrees C) (p=0.025, p=0.005). There was de novo expression of UCP-3 in the liver of the fenofibrate group. These data suggest that increased energy dissipation, via hepatic UCP-3 by fenofibrate, contribute to decreased weight gain in obese rats.

To construct a sensory neuropathy model, excess pyridoxine (150 mg/kg s.i.d.) was injected subcutaneously in dogs over a period of 7 days. During the administrations period, the dogs experienced body weight reduction and proprioceptive loss involving the hindquarters. After pyridoxine administration was completed, electrophysiological recordings showed that the M wave remained at a normal state, but the H-reflex of the treated dogs disappeared at 7 days. The dorsal funiculus of L4 was disrupted irregularly in the axons and myelin with vacuolation. The dorsal root ganglia of L4, and sciatic and tibial nerves showed degenerative changes and vacuolation. However, the lateral and ventral funiculi of L4 showed a normal histopathologic pattern. Although this subcutaneous administration method did not cause systemic toxicity and effectively induced sensory neuropathy, this study confirmed the possibility of producing a pyridoxine-induced sensory neuropathy model in dogs with short-term administration.

AIMTo investigate effects of quercetin on weight and histology of testis and accessory sex organs and on sperm quality in adult male rats.
METHODSMale Sprague-Dawley rats were injected s.c. with quercetin at the dose of 0, 30, 90, or 270 mg/kg body weight/day (hereafter abbreviated Q0, Q30, Q90 and Q270, respectively), and each dose was administered for treatment durations of 3, 7 and 14 days.
RESULTSFrom our study, it was found that the effects of quercetin on reproductive organs and sperm quality depended on the dose and duration of treatment. After Q270 treatment for 14 days, the weights of testes, epididymis and vas deferens were significantly increased, whereas the weights of seminal vesicle and prostate gland were significantly decreased, compared with those of Q0. The histological alteration of those organs was observed after Q270 treatment for 7 days as well as 14 days. The sperm motility, viability and concentration were significantly increased after Q90 and Q270 injections after both of 7 and 14 days. Changes in sperm quality were earlier and greater than those in sex organ histology and weight, respectively.
CONCLUSIONOverall results indicate that quercetin might indirectly affect sperm quality through the stimulation of the sex organs, both at the cellular and organ levels, depending on the dose and the duration of treatment. Therefore, the use of quercetin as an alternative drug for treatment of male infertility should be considered.

Although enhanced appetite and weight gain are potential side effects of treatment with antipsychotic agents, particularly olanzapine and clozapine, the mechanisms underlying these side effects are poorly understood. Leptin and ghrelin were recently identified as hormones that play crucial roles in the regulation of energy balance and glucose metabolism. To elucidate relationships between weight change and plasma levels of ghrelin and leptin, we investigated the circulating ghrelin and leptin levels and body weight during olanzapine treatment. Twenty-four patients with schizophrenia were examined during 6-month administration of olanzapine. Ghrelin, leptin, weight and body mass index (BMI) were measured before and after 2, 4, 8, 12, 16, and 24 weeks of olanzapine treatment. The concentration of glucose and various lipid metabolic parameters were measured at baseline and at 24 weeks. Significant increases in weight, BMI and leptin were observed at week 24. On the other hand, the serum levels of ghrelin decreased significantly after olanzapine treatment. In addition, the level of ghrelin was negatively correlated with the leptin level, BMI and weight. The leptin level was positively correlated with both BMI and weight. Ghrelin is associated with metabolic changes, in combination with leptin, during olanzapine treatment. However, further large-scale and longitudinal studies are warranted to elucidate the metabolic changes involving ghrelin, leptin and insulin during treatment with antipsychotics.

OBJECTIVE:
To screen the active components from Fuzheng Huayu Recipe (FZHY) and redesign a new recipe composed of the active components, and validate the effect of active components formulation from FZHY against liver fibrosis.
METHODS:
Thirty-two components from FZHY were evaluated for their activities against liver fibrosis respectively, with 6 kinds of cell models in vitro, including oxidative stressed hepatocyte in L-02, hypoxia injured/proliferative hepatic sinusoidal endothelial cells in SK-HEP-1 and human hepatic sinusoidal endothelial cells (HHSEC), and activated hepatic stellate cell in LX-2. The comprehensive activity of each component against liver fibrosis was scored according to the role of original herbs in FZHY and cell functions in fibrogenesis. Totally 7 active components were selected and combined with equal proportion to form a novel active components formulation (ACF). The efficacy of ACF on liver fibrosis were evaluated on activation of LX-2 and proliferation of HHSEC in vitro and in liver fibrosis model mice induced by dimethylnitrosamine (DMN). Totally 72 mice were divided into 6 groups using a random number table, including normal, high-dose ACF control (20 µ mol/L × 7 components/kg body weight), model, low-, medium-, high-dose ACF groups (5, 10, 20 µ mol/L × 7 components/kg body weight, respectively). Hematoxylin eosin and Sirius red stainings were used to observe inflammation and fibrosis change of liver tissue; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were utilized to observe the effect of ACF on ultrastructure of hepatic sinusoids.
RESULTS:
Fifteen components from FZHY showed higher scores for their activity on against liver fibrosis. Among them, 7 components including tanshinone II A, salvianolic acid B, cordycepin, amygdalin, quercetin, protopanaxatriol, and schizandrin B were recombined with equal proportions to form ACF. ACF at 1,2, 4 µ mol/L showed strong inhibitory effects on activation of LX-2 and proliferation of HHSEC in vitro (all P<0.01). Compared with the model group, ACF attenuated liver collagen deposition, improved sinusoidal capillarization in a dose-dependent manner (all P<0.05).
CONCLUSION
ACF exerts a satisfactory effect against experimental liver fibrosis and attenuates sinusoidal capillarization, which warrant a further research and development for herbal components formulation on liver fibrosis.

OBJECTIVETo compare differences in the intelligence and physical developmental levels of children with congenital hypothyroidism (CH) who received initial treatment at different times.
METHODSForty-nine children with CH diagnosed by neonatal screening between September 2008 and September 2011 were enrolled in this study. According to the timing of initial treatment with thyroid hormone, they were classified into two groups: <1 month and 1 to 3 months of life. At 6 months old, 1 year and 2 years old, their intelligence levels were evaluated by Gessell test. Their physical developmental levels were also measured. Their thyroid functions were examined with fluorescence immunoassay.
RESULTSWith treatment, there were no significant differences in thyroid hormones (FT3, FT4 and TSH) between the two groups (P>0.05) at 6 months old, 1 year and 2 years old. However, heights and weights in the <1 month treatment group were significantly higher than in the 1 to 3 months treatment group at all time points (P<0.05). At 6 months old, intelligence developmental levels in the <1 month treatment group were better than the 1 to 3 months treatment group (P<0.05) but significant differences were not noted at 1 and 2 years old (P>0.05).
CONCLUSIONSThe timing of initial treatment with thyroid hormone appears to be associated with the intelligence and physical development in children with CH. Treatment starting at less than 1 month of life contributes to improved physical and intelligence development compared with treatment starting at 1 to 3 months of life.

OBJECTIVELong-term inhaled corticosteroids are the preferred treatment for asthma, but their safety still controversial. The aim of the present study was to explore the effects of inhaled corticosteroids on bone age and growth in children with asthma.
METHODSSeventy-three children with asthma received inhaled fluticasone treatment at a starting dosage of 250 μg/d for 3 months, when the dosage was reduced by a third. Three months later, the patients were treated with fluticasone at a dosage of 125 μg/d for 6 months. Bone age, heights and weights were measured before and one year of treatment.
RESULTSThe increase in the heights, weights and RUS (radius, ulna and short finger bones) bone age of the children with asthma after one year of treatment was not significantly different from healthy children. There were no significant differences in body mass index (BMI) before and after one year of treatment, however the level of carpal bone age [-0.2(-0.6,0.8) years] was delayed after therapy compared to before treatment [-0.5(-1.0,0.6) years] (P<0.05).
CONCLUSIONSTreatment with inhaled corticosteroids for 1 year may suppress the level of carpal bone age, but the level of RUS bone age, heights, weights and BMI are not affected. It is necessary to monitor the growth of children with asthma who receive long-term inhaled corticosteroid treatment.

BACKGROUNDThe neurogenesis in retina of adult mammals is generally abolished, and this renders the retina lack of regenerative capacity. Despite this, there is a small population of nestin-positive cells in the ciliary epithelium which retains neurogenic potential. The present study aimed at investigating the effect of two drugs, corticosterone and paroxetine, on the cell proliferation of the ciliary body.
METHODSAdult Sprague-Dawley rats were given vehicle, corticosterone, paroxetine, or both corticosterone and paroxetine treatment for 14 days. Cell proliferation in the ciliary body was quantified using 5-bromo-2-deoxyuridine (BrdU) immunohistochemistry. Co-labelling of BrdU and stem cell marker was used to phenotype the BrdU immunoreactive cells.
RESULTSCorticosterone treatment suppressed while paroxetine treatment increased the cell proliferation of the ciliary body. Co-labelling with cell markers revealed that the BrdU positive cells also showed nestin expression but not glial fibrillary acidic protein (GFAP).
CONCLUSIONSThe results illustrate that proliferation of retinal progenitor cells situated in ciliary body are subjected to regulation by selective serotonin reuptake inhibitors (SSRI) and corticosteroid, which is similar to our previous findings in neurogenic regions in central nervous system (CNS). Paroxetine treatment could reverse the suppressive effect of corticosterone on ciliary body cell proliferation. This provides information for future investigation of retinal stem cell biology and potential treatment of retinal degenerative diseases.

OBJECTIVETo investigate the potential developmental toxicity of Radix Ophiopogonis decoction in SD rats.
METHODTimed-pregnant SD rats were given Radix Ophiopogonis decoction (26.9 g x kg(-1)) or vehicle (distilled water) by gavage on gestation days 6-17. Maternal clinical sign, abortions, premature deliveries, and body weight were monitored throughout gestation. At termination (gestation days 20) pregnant females were evaluated for clinical status and gestational outcome; live fetuses were examined for gender, external, visceral and skeletal malformation and variations.
RESULTNo deaths, premature deliveries or dose-related clinical signs were attributed to Radix Ophiopogonis decoction. Maternal body weight and body weight gain were not affected. There were no effects on fetus weight and viability, incidences of fetal malformation and variation.
CONCLUSIONThese results demonstrated that Radix Ophiopogonis decoction had no detectable adverse effects in either the treated F0 female rats or the fetuses.
