BACKGROUND: In smokers, smoking causes many disease entities including cancers, chronic pulmonary diseases and cardiovascular diseases. Passive smoking is also accepted as a carcinogen and its adverse health effects are emphasized. We measured blood vitamin A, C, E (alpha-, beta- and gamma-tocopherol), coenzyme Q10 and urine cotinine concentrations in nonsmokers and smokers. METHODS: Twenty-one healthy nonsmokers and 24 healthy smokers were included in this study. Smoking status was assessed with a self-reported questionnaire. Plasma was analyzed for coenzyme Q10 and serum for vitamin A, C, E using HPLC (Agilent Technologies Inc., USA) and random urine for cotinine using LC/tandem mass spectrometry (Applied Biosystems Inc., Canada). RESULTS: Smokers had significantly lower serum concentrations of vitamin C than nonsmokers (P=0.0005). No significant differences in concentrations of serum vitamin A, E, and plasma coenzyme Q10 were observed. Smokers had highly elevated urine cotinine levels (1,454+/-903 ng/mL). In 16 (76.2%) of 21 nonsmokers, urine cotinine was detected (3.25+/-4.08 ng/mL). The correlations between urine cotinine and blood antioxidants levels were not found. Neither, the correlation between smoking status and blood antioxidants & urine cotinine was found. CONCLUSIONS: This study shows that smokers had significantly lower vitamin C levels among nonenzymatic antioxidants, namely, vitamin A, C, E and coenzyme Q10. High detection rate of urine cotinine in nonsmokers show the seriousness of passive smoking exposure, therefore more social efforts should be directed to reduce passive smoking exposure.

OBJECTIVEEffects of red palm oil on major plasma carotenoids, tocopherol, retinol and serum lipids were evaluated when used in Chinese diet.

METHODSRed palm oil group (RPO) composed of 20 male subjects(aged 18-32) and soybean oil group (SBO) composed of 22 male subjects (aged 18-32). Dietary fat provided about 28% of total calories, and the test oil accounted for about 60% of total dietary fat. In the 3 weeks of pretest period, diets were prepared with soybean oil, and then in the next 6 weeks subjects in each group consumed the diet prepared by test oil.

RESULTSPlasma alpha-carotene, beta-carotene and lycopene concentration of RPO group significantly increased at the time of interim (21 days) and of the end (42 days) (P < 0.05), and alpha-tocopherol concentration significantly increased at the time of the end (42 days) in this study. Though Chinese plasma retinol level was relatively low when compared with that of Westerners, red palm oil diet showed no significant effect on adult Chinese plasma retinol level. Serum concentration of total cholesterol, triglyceride, high density lipoprotein cholesterol, apolipoprotein AI and apolipoprotein B of all subjects showed no significant changes in RPO group during the study.

CONCLUSIONSThe data in our study suggest that red palm oil is a good source of carotenoids and vitamin E when used in Chinese diet preparation, and it can significantly increase plasma concentration of alpha-carotene, beta-carotene, lycopene and alpha-tocopherol.

The serum levels of antioxidant materials (alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein, lycopene, alpha-tocopherol, gamma-tocopherol, retinol) of the healthy Korean middle-aged adults (n = 373) were measured and their relationships with the serum lipids and anthropometric indices were analyzed. The serum levels of beta-cryptoxanthin, beta-carotene, lutein were higher than those of lycopene and alpha-carotene. The levels of all measured carotenoids except lutein were significantly higher in females than in males, but retinol level was vice versa. There was a tendency of increase in serum levels of antioxidant vitamins with increasing age. The serum carotenoid levels had a positive correlation with serum cholesterol and a negative correlation with serum triglyceride. The serum levels of tocopherols or retinol showed a significantly positive relationship with blood cholesterol or triglyceride. In overall, anthropometric indices showed negative relations with serum carotenoids levels, but vice versa with serum tocopherol or retinol levels. Particularly, beta-carotene and lutein levels showed a significantly negative relation with blood pressure in male subjects. The serum levels of alpha-carotene, beta-carotene and beta-cryptoxanthin had significantly negative relations with body fat-related indices in female subjects. The results demonstrated that blood antioxidants levels differed by sex and age, and had significant relations with blood lipid levels and anthropometric indices. Therefore, the rationale and significance of the relationships need to be elucidated in the future study related to dietary intakes and life style.

OBJECTIVES: Pentoxifylline (PTX) is a methylxanthine derivative that has been implicated in the pathogenesis of peripheral vessel disease and intermittent lameness. The purpose of this study was to investigate the effect of PTX and tocopherol in patients diagnosed with osteoradionecrosis (ORN), bisphosphonate-related osteonecrosis of the jaw (BRONJ), and chronic osteomyelitis using digital panoramic radiographs.MATERIALS AND METHODS: This study was performed in 25 patients who were prescribed PTX and tocopherol for treatment of ORN, BRONJ, and chronic osteomyelitis between January 2014 and May 2018 in Seoul National University Dental Hospital. Radiographic densities of the dental panorama were compared prior to starting PTX and tocopherol, at 3 months, and at 6 months after prescription. Radiographic densities were measured using Adobe Photoshop CS6 (Adobe System Inc., USA). Blood sample tests showing the degree of inflammation at the initial visit were considered the baseline and compared with results after 3 to 6 months. Statistical analysis was performed using the Mann–Whitney test and repeated measurement ANOVA using IBM SPSS 23.0 (IBM Corp., USA).RESULTS: Eight patients were diagnosed with ORN, nine patients with BRONJ, and the other 8 patients with chronic osteomyelitis. Ten of the 25 patients were men, average age was 66.32±14.39 years, and average duration of medication was 151.8±80.65 days (range, 56–315 days). Statistically significant increases were observed in the changes between 3 and 6 months after prescription (P<0.05). There was no significant difference between ORN, BRONJ, and chronic osteomyelitis. Only erythrocyte sedimentation rate (ESR) was statistically significantly lower than before treatment (P<0.05) among the white blood cell (WBC), ESR, and absolute neutrophil count (ANC).CONCLUSION: Long-term use of PTX and tocopherol can be an auxiliary method in the treatment of ORN, BRONJ, or chronic osteomyelitis in jaw.

A group of 101 women, aged 40-65 years consisted of 48 premenopausal subjects and 53 postmenopausal ones living in Daegu and Gyeongbuk area in Korea were evaluated with their general characteristics, lifestyle factors, nutrient and phytoestrogen intakes, blood and urinary indices concerning antioxidant status and bone metabolism. Body mass index (BMI), waist hip ratio (WHR) and systolic blood pressure (SBP) of the postmenopausal women were significantly higher (23.8, 0.86, and 126.9 mmHg, respectively) than those of the premenopausal women (22.6, 0.82, and 115.9 mmHg; respectively). Nutrient intakes of the postmenopausal and premenopausal groups were not different except lower fat intake and higher dietary fiber and iron intakes in the postmenopausal group. Daily total phytoestrogen intake was significantly higher in the postmenopausal group (48.54 mg) than the premenopausal (31.41 mg) and was resulted mostly from higher intakes of daidzein and genistein from soy and soy products (45.42 mg vs 28.91 mg). Serum genistein level and excretion of enterolactone, major lignan metabolite, were not very different between the two groups. Serum retinal and alpha- tocopherol levels were higher in the postmenopausal group but TBARS levels were not different between the two groups. Serum osteocalcin (7.18 ng/mL) and urinary deoxypyridinoline (7.15 nmol/mmol creatinine), in the postmenopausal group were significantly higher than those in the premenopausal group (4.80 ng/mL, 5.95 nmol/mmol creatinine). Urinary excretion of enterolactone was positively correlated with serum osetocalcin in premenopausal women and serum genistein negatively correlated with the urinary DPD in postmenopausal women. Dietary phytoestrogen intake was negatively correlated with serum level of TBARS in all subjects. It is concluded that the effect of total phytoestrogen intake is beneficial on body antioxidant status in all middle-aged women regardless of menopause but the effect on bone metabolism appears different by the type of the phytoestrogen and the menopausal state.

BACKGROUND: It is known that hyperglycemia increase oxidative stress. Korean type 2 diabetic patients usually appear to be insulin deficient and insulin resistant. The blood glucose control can be normalized by the intensive insulin therapy. It has been reported that hyperinsulinemia have harmful effects on oxidative stress. The purpose of this study was to determine whether continuous subcutaneous insulin infusion (CSII) therapy by insulin pump affects the defense mechanism of oxidative stress in Korean type 2 diabetic patients. METHODS: Fasting blood from eighty three subjects was collected prior to starting CSII therapy using portable insulin pump and after hospitalization for 2 weeks. Serum and red blood cell lipid peroxide concentrations were analyzed by Yagi's methods. Serum tocopherol and vitamin C concentrations were measured by HPLC. Red blood cell glutathione peroxidase, superoxide dismutase and catalase activities were also measured. RESULTS: The mean age of subjects were 50.0+/-10.9 years, and they had diabetes for 8.4+/-5.8 years. Their average body mass index was 23.4+2.7 kg/m2. Their blood glucose levels were not controlled by oral hypoglycemic agents, diet and exercise treatment. Patients were divided into two categories according to blood glucose levels prior to CSII treatment. One category consists of patients with less than 11.1 mmol/L of average daily blood glucose levels prior to CSII treatment (the controlled group). The other category consists of patients with more than 11.1 mmol/L of average daily blood glucose levels (the uncontrolled group). Patients in the uncontrolled group had higher serum lipid peroxide levels than those in the controlled group before CSII therapy. After 2 weeks of CSII therapy, oxidative stress was not changed in controlled and uncontrolled groups. Serum insulin levels of all patients were increased after CSII treatment, but the levels before and after treatments were in the normal range, not hyperinsulinemic. Also, serum insulin levels did not correlate with serum lipid peroxide levels regardless of CSII treatment. Average serum vitamin C levels were remarkably increased after the therapy in all patients, but average serum total tocopherol levels was not altered. Also, activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, and catalase were not significantly changed. CONCLUSION: The blood glucose levels were normalized with the normal ranges of serum insulin levels after two weeks of CSII treatment. However, serum lipid peroxide levels were not changed even though serum vitamin C levels were increased. It is concluded that the oxidative stress of Korean type 2 diabetic patients are not changed after two weeks of CSII treatment, but there may be possibility the longer duation of CSII therapy may gradually improve oxidative stress.

BACKGROUND/OBJECTIVES: Diabetes mellitus (DM) is a major chronic disease which increases global health problems. Diabetes-induced renal damage is associated with inflammation and fibrosis. Alpha (AT) and gamma-tocopherols (GT) have shown antioxidant and anti-inflammatory effects in inflammation-mediated injuries. The primary aim of this study was to investigate effects of AT and GT supplementations on hyperglycemia induced acute kidney inflammation in alloxan induced diabetic mice with different levels of fasting blood glucose (FBG). MATERIALS/METHODS: Diabetes was induced by injection of alloxan monohydrate (150 mg/kg, i.p) in ICR mice (5.5-week-old, male) and mice were subdivided according to their FBG levels and treated with different diets for 2 weeks; CON: non-diabetic mice, m-DMC: diabetic control mice with mild FBG levels (250 mg/dl < or = FBG < or = 450 mg/dl), m-AT: m-DM mice fed AT supplementation (35 mg/kg diet), m-GT: m-DM mice with GT supplementation (35 mg/kg diet), s-DMC: diabetic control mice with severe FBG levels (450 mg/dl < FBG), s-AT: s-DM mice with AT supplementation, s-GT: s-DM mice with GT supplementation. RESULTS: Both AT and GT supplementations showed similar beneficial effects on NFkappaB associated inflammatory response (phosphorylated inhibitory kappa B-alpha, interleukin-1beta, C-reactive protein, monocyte chemotactic protein-1) and pre-fibrosis (tumor growth factor beta-1 and protein kinase C-II) as well as an antioxidant emzyme, heme oxygenase-1 (HO-1) in diabetic mice. On the other hands, AT and GT showed different beneficial effects on kidney weight, FBG, and oxidative stress associated makers (malondialdehyde, glutathione peroxidase, and catalase) except HO-1. In particular, GT significantly preserved kidney weight in m-DM and improved FBG levels in s-DM and malondialdehyde and catalase in m- and s-DM, while AT significantly attenuated FBG levels in m-DM and improved glutathione peroxidase in m- and s-DM. CONCLUSIONS: The results suggest that AT and GT with similarities and differences would be considered as beneficial nutrients to modulate hyperglycemia induced acute renal inflammation. Further research with careful approach is needed to confirm beneficial effects of tocopherols in diabetes with different FBG levels for clinical applications.

Infertility is a world wide problem affecting up to 15% of married couples. Although it is well known that male factor is the important cause of the infertility in 40-50% of the cases, the appropriate drugs for treating this condition have not yet been established. With certain exceptions, the etiology of many cases of male infertility is unknown. For such cases, various drugs including both hormonal and non-hormonal agents are sometime prescribed, but there have been no entirely satisfactory results. The present investigation would assess the effectiveness of Korean Ginseng, herbal medicine in the treatment of male infertility during the period from September to December, 1988, at the Andrology Clinic of the Department of Urology, Seoul National University Hospital. This herbal medicine was selected because its ingredients accelerate the metabolism of lipids and synthesis of DNA, RNA and proteins. This medicine contains ingredients which build resistance against stress since many of male infertility are under stress and also is to control immunological disorders. Ginseng has steroid-like, anti-allergic and anti-inflammatory actions, and accommodates the blood-testis barrier, improve digestive functions and peripheral blood flow. Accordingly, Ginseng has been used as an agent restoring healthy conditions to maintain homeostasis or to keep physical and mental balance. Extensive chemical investigation on Ginseng has revealed that Ginseng contains characteristic dammarane-type triterpenoid saponins as the main principles. These saponins are called ginsenosides and represent the principal pharmacological actions of Ginseng. The ginsenosides react at the hypothalamus-pituitary-gonadal axis. The decreases of sexual drive and disorders of fecundity under challenge of stress are prevented by oral administration of ginsenosides. To assess the efficacy of treatment with Ginseng which is alleged to improve spermatogenesis in idiopathic infertile selected patients. Participants in this study are men with primary idiopathic oligospermia and asthenospermia. The inclusion criteria would be as follows : a) men aged 20-40 years, whose female partners are entirely normal. b) men having vaginal intercourse with one partner and without psycho-sexual problems. c) men willing to enter this clinical trial and relying only on the drug administered throughout the study. d) no history of serious chronic physical or psychological diseases. e) men whose female partners are not using any method of birth control. f) men with no history of drugs to treat sperm disorders within 3 months. A total of 12 patients with sperm counts of less than 20 x 10 6/ml (oligospermia group), and 5 patients with sperm motility of less than 20% (asthenospermia group) are selected as the study subjects. Parameters to be assessed are as follows : Before and after Ginseng administration, history taking, physical examination with testis size measurement, laboratory works including urinalysis, CBC, seminal fructose, semen analyses (pH, volume, density, motility, activity grade, morphology, fertility unit, and WBC), plasma hormonal assays (FSH, LH, testosterone, estradiol, and prolactin). Before starting the treatment, 2 semen samples are obtained preteded by 3 days of abstinence. For follow-up, patients will have a semen sample taken every month while in treatment. After the treatment, more than 2 semen analyses will be undertaken for the final evaluation. Treatment scheme is as follows : The composition of the Ginseng extract used in this clinical trial consisted of the standardized highly concentrated Ginseng extract G115, 100mg : concentrated standardized lectithin, 95mg , alpha tocopherol, 10mg ; and excipients q.s.ad. This Ginseng extract named Ginsana capsule produced by Pharmaton-Korea Co., Ltd. Four capsules of Ginsana are given twice a day by mouth before meal for more than 90 days to be justified on the basis of general assumption that spermatogenesis cycle lasts approximately 74 days. The results of the clinical investigation are considered to be effective, if more than double of improvemant being noted on the count or more than 30% ot improvement being noted on motility beyond the pre-treatment levles. Clinical characteristics of a total of 17 patients are listed in the table 1. The outcomes of this trial are presented as follows : (tables 2 and 3). Coital frequency increased from 2.6/week before Ginsana exposure to 3.1/week after the treatment. General health such as stamina, body weight and spirits improved in 10 patients of the 17 after Ginsang treatment. Regarding hormonal partmeters (table 2), Plasma FSH and LH were not changed much before and after Ginsana administration. Patients with low FSH and LH levels before the treatment and patients with high range of prolactin levels before the treatment have a tendency to improve more in semen parameters after the treatment. Hyperestrogenemia was decreased and plasma testosterone levels increased after Ginsana treatment. Subsequently, T/E2 ratio resulted in normal to help spermatogenesis. Regarding the semen parameters (table 3), sperm counts increased in 58% of the patients in oligosperrnia group after oligospermia group. Sperm motility improved in 33% of the patients rn oligospermia group after the treatment. Mean motility increased from 34% to 45% after the treatment in oligospermia group. Activity grade and fertility unit were also improved in oligospermia group after the treatment Other parameters such as volume, normal morphology, pH and seminal fructose were not changed significantly before and after Ginstna treatment. Only one case showed an improvement in sperm counts and motility of a total of 5 patients with asthenospermia. Pregnancy resulted in 2 patients of improved cases and 1 patient of not improved cases in oligopsermia group after Ginsana administration. So that, pregnancy rate was 25 % of the oligospermia group. The study results of some imvestigators are summarized in the table 4. From these results, Ginsana appears mainly act on testis directly, restore the steroidogenesis, resulting in the stimulation of spermatogenesis. in conclusion, the authors clinical experience confirmed that Ginsana, a traditional Chinese medicine, appears to be of value particularly in the trettment of idiopethic oligospermia without any noticeabel adverse side effects.
