Glimepiride, a third generation sulfonylurea, is an antihyperglycemic agent widely used to treat type 2 diabetes mellitus. In this study, an untargeted urinary metabolomic analysis was performed to identify endogenous metabolites affected by glimepiride administration. Urine samples of twelve healthy male volunteers were collected before and after administration of 2 mg glimepiride. These samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and then subjected to multivariate data analysis including principal component analysis and orthogonal partial least squares discriminant analysis. Through this metabolomic profiling, we identified several endogenous metabolites such as adenosine 3′, 5′-cyclic monophosphate (cAMP), quercetin, tyramine, and urocanic acid, which exhibit significant metabolomic changes between pre- and posturine samples. Among these, cAMP, which is known to be related to insulin secretion, was the most significantly altered metabolite following glimepiride administration. In addition, the pathway analysis showed that purine, tyrosine, and histidine metabolism was affected by pharmacological responses to glimepiride. Together, the results suggest that the pharmacometabolomic approach, based on LC-MS/MS, is useful in understanding the alterations in biochemical pathways associated with glimepiride action.

The basidiomycete Laetiporus sulphureus var. miniatus belongs to the Aphyllophorales, Polyporaceae, and grows on the needleleaf tree. The fruiting bodies of Laetiporus species are known to produce N-methylated tyramine derivatives, polysaccharides, and various lanostane triterpenoids. As part of our ongoing effort to discover biologically active compounds from wood-rotting fungi, an anti-inflammatory triterpene, LSM-H7, has been isolated from the fruiting body of L. sulphureus var. miniatus and identified as acetyl eburicoic acid. LSM-H7 dose-dependently inhibited the NO production in RAW 264.7 cells without any cytotoxicity at the tested concentrations. Furthermore it suppressed the production of proinflammatory cytokines, mainly inducible nitric oxide synthase, cyclooxygenase-2, interleukin (IL)-1beta, IL-6 and tumor necrosis factor alpha, when compared with glyceraldehyde 3-phosphate dehydrogenase. These data suggest that LSM-H7 is a crucial component for the anti-inflammatory activity of L. sulphureus var. miniatus.

OBJECTIVE: To determine the 9 month period effect of botulinum toxin A (BoNT-A) injection into the salivary gland in children with neurologic disorders and sialorrhea by qualified parent/caregiver-administered questionnaires. METHOD: A total of 17 patients (age 7.6+/-4.24 years) were enrolled in this study. The degree of sialorrhea was assessed at the baseline, 2 weeks, 1, 2, 4, 6 and 9 months after injection. The Drooling Count (DC) was assessed as an objective measurement. The Drooling Frequency and Severity Scale (DFS) and the Teacher Drooling Scale (TDS) were evaluated as a subjective measurement. BoNT-A (0.5 unit/kg) was injected into each submandibular and parotid gland under ultrasonography-guidance. RESULTS: DC, DFS and TDS showed significant improvement at 2 weeks, 1, 2, 4, 6, and 9 months follow-up (p<0.05). Twelve of 17 cases (70.5%) showed more than 50% reduction in DC from the baseline value. CONCLUSION: Ultrasonography-guided BoNT-A injection into the submandibular and parotid gland was a safe and effective method to treat sialorrhea in children with neurologic disorders.

The present study was to investigate the effects of Lycii Cortex Radicis (LCR), the root bark of lycium (Lycium chenese Miller) and ginger (Gin) on body lipid status and serum levels of cytokines. Sprague-Dawley (SD) male rats weighing 193.6 +/- 16.8 g were divided into five groups, including one low fat (LF) and four high fat groups, i.e. HF-Control, HF-LCR, HF-Gin and HF-LCR + Gin groups. Diets for HF-LCR, HF-Gin and HF-LCR + Gin groups contained purified extracts having 0.2 g LCR tyramine, ginerol and 0.1 g tyramine plus 0.02 g gingerol per kg, respectively. Compared with those of the HF-Control total serum cholesterol level decreased, and HDL-cholesterol level increased in the HF-LCR group and serum triglyceride levels decreased in the three experimental groups fed the purified extracts. Liver cholesterol level was lower in the HF-LCR group than the HF-Control group, but triglyceride levels, which were increased by high fat diets were not changed by significantly by LCR or ginger extracts. Fecal lipid excretion was higher in the HF-LCR and HF-Gin groups, but cholesterol excretion was lower in the HF-Gin group than in the HF-Control group. The activities of liver cytosolic glucose-6-phosphate dehydrogenase and malic enzyme were lower in the HF-LCR + Gin group than in the HF-Control group. Serum adiponectin levels did not differ among the five groups, while leptin level was lower in the HF-Gin group and C-reactive protein levels were lower in the HF-Gin and the HF-LCR + Gin groups than in the HF-Control group. It is concluded that LCR can be utilized as an ingredient for lipid-lowering functional foods in the form of purified extract and addition of small amount of ginger extract would be useful for reducing one of the inflammatory cytokines to help prevent atherosclerosis.

Since the elderly population has been increasing recently in our country, old male patients with testosterone deficiency syndrome (TDS) with a significantly decreasing quality of life are becoming increasingly common. TDS in males is defined as a biochemical syndrome associated with advancing age and characterized by clinical manifestation and a deficiency in the serum testosterone level. These patients should be treated with extrinsic testosterone to improve quality of life. TDS in males should be diagnosed in the case of clinical manifestation with serum total testosterone <8 nmol/L (230 ng/dL) or calculated free testosterone <225 pmol/L (65 pg/mL) but not diagnosed in the case of serum total testosterone >12 nmol/L (350 ng/dL). Products for testosterone replacement therapy (TRT) are administrated orally, transdermally, and through injectable preparations. Daily testosterone undecanoate is widely used for oral administration with good results and no hepatotoxicity. Short-acting intramuscular preparations are very effective but show wide swings in the resulting supra-physiological level of serum testosterone. Long-acting intramuscular preparations is also very effective and lasting for 3 months with normal physiologic levels. Many products for TRT on the market are effective and generally safe. However, those have a few significant adverse events each other. The ideal product should have notable effectsand few side effects, (such as selective androgen receptor modulators), be easy to administrate, maintain physiologic serum concentration, and be inexpensive. TDS in males can easily be correct by TRT. However, the advantages and disadvantages of the individual products and follow-up management of complicated adverse events should be understood before starting and maintaining TRT.

OBJECTIVE: The aim of the study was to evaluate the effectiveness of ultrasouond-guided salivary gland injection of botulinum toxin A (BTX-A) for posterior drooling. METHOD: 11 patients with brain lesion (9 cerebral palsy, 1 hypoxic ischemic encephalopathy and 1 mental retardation) with posterior drooling (an initial PDAS score greater than 2) and related pulmonary problems were recruited. Drooling severity was measured at baseline, 4 weeks, 3 months and 6 months after botulinum toxin A injection, by using Teacher Drooling Scale (TDS), Visual Analogue Scales (VAS), Drooling Score System (DSS)-severity, frequency and Posterior Drooling/Aspiration System (PDAS). RESULTS: The TDS, DSS-severity, DSS-frequency, VAS, PDAS were significantly reduced at 4 weeks and 3 months after BTX-A injection into salivary glands compared to pre-injection (p<0.05). However, there were no significant changes at 6 months compared to pre-injection level. CONCLUSION: BTX-A injection into salivary glands may improve anterior drooling in patients with brain lesions. Furthermore BTX-A injection into salivary glands may also decrease the posterior drooling which might related to respiratory symptoms in aspiration pneumonia.

PURPOSE: This study was conducted to investigate the relationship between serum total testosterone levels and scores on the Aging Male's Symptom (AMS) scale and the International Index of Erectile Function (IIEF) in men with erectile dysfunction with testosterone deficiency syndrome (TDS). MATERIALS AND METHODS: From January 2005 to July 2008, 134 patients who complained of sexual dysfunction such as erectile dysfunction or decreased libido as the main symptoms of TDS with serum total testosterone levels less than 3.5 ng/ml were evaluated by independent t-test and linear regression analysis, respectively. Patients with treated hypogonadism within 6 months, with a history of taking a PDE5 inhibitor or an antidepressant for a depressive disorder, or who had metabolic syndrome were excluded from this study. RESULTS: The AMS scale and its 3 subdomain scores were not significantly correlated with the total testosterone level. By contrast, the total IIEF score and the score of each IIEF domain except sexual desire showed a weakly significantly positive correlation with serum total testosterone. CONCLUSIONS: In TDS patients with erectile dysfunction, there was a low relationship between serum total testosterone levels and the AMS scale and a weakly positive correlation between total testosterone levels and all IIEF domains except sexual desire. There was a low relationship between the AMS scale, the sexual desire domain score of the IIEF, and total testosterone. We should understand these limitations when evaluating patients with erectile dysfunction with TDS. New scales should be developed for the evaluation of erectile dysfunction in these patients.

The aim of the present study was to investigate the hypocholesterolemic effect and potential of tyramine derivatives from Lycii Cortex Radicis (LCR), the root bark of lycium (Lycium chenese Miller) in reducing lipid peroxidation. The activities of enzymes, hepatic 3-hydroxy 3-methylglutaryl (HMG) CoA reductase and acyl-CoA:cholesterol acyltransferase (ACAT) and LDL oxidation were measured in vitro and animal experiments were also performed by feeding LCR extracts to rats. The test compounds employed for in vitro study were trans-N-p-coumaroyltyramine (CT) and trans-N-feruloyltyramine (FT), LCR components, N-(p-coumaroyl)serotonin (CS) and N-feruloylserotonin (FS) from safflower seeds, ferulic acid (FA) and 10-gingerol. It was observed that FT and FS at the concentration of 1.2 mg/mL inhibited liver microsomal HMG CoA reductase activity by ~40%, but no inhibition of activity was seen in the cases of CT, CS, FA and 10-gingerol. Whereas, ACAT activity was inhibited ~50% by FT and CT, 34-43% by FS and CS and ~80% by 10-gingerol at the concentration of 1 mg/mL. A significant delay in LDL oxidation was induced by CT, FT, and 10-gingerol. For the animal experiment, five groups of Sprague-Dawley male rats were fed high fat diets containing no test material (HF-control), 1 and 2% of LCR ethanol extract (LCR1 and LCR2), and 1% of extracts from safflower seed (Saf) and ginger (Gin). The results indicated that total cholesterol level was significantly lower in Saf, LCR2 and Gin groups, and HDL cholesterol level was lower only in Gin group when compared with HF-control group; while there was no difference in the serum triglyceride levels among the five experimental groups. The level of liver cholesterol was significantly lower in LCR1 and LCR2 groups than HF-control. Serum levels of TBARS were significantly lower only in LCR2 group when compared with HF-control group. From the observed results, we concluded that LCR can be utilized as a hypocholesterolemic ingredient in combination with ginger, especially for functional foods.
