Herpes zoster as a result of reactivated varicella-zoster virus is characterized by vesicular eruptions on skin and painful neuralgia in the dermatome distribution. Pain during an acute phase of herpes zoster has been associated with a higher risk of developing postherpetic neuralgia. The current therapies for herpes zoster including analgesics and sympathetic nerve block as well as antiviral agents are important to alleviate pain and prevent postherpetic neuralgia. However, in some cases, the pain does not respond well to these treatments. We had a case in which a patient with herpes zoster did not respond to conventional therapy so we attempted to administer intravenous infusion of vitamin C which resulted in an immediate reduction in the pain.

This experiment was conducted to compare the effects of vitamin C supplemented in either feed or water on the performance and carcass characteristics of broilers during the hot season. For a 6 week feeding trial, a total of 330 broiler chicks (Ross, 4 d old, average 57 g BW) were alloted to five treatments. The treatments of vitamin C (VC) supplementation were 1) 0 ppm VC, 2) 10 ppm VC in feed, 3) 20 ppm VC in feed, 4) 5 ppm VC in water and 5) 10 ppm VC in water. During the starter phase (0-3 week), chicks on non-supplemented group grew slower (p<0.01) than the supplemented ones, and a similar trend was also noted during finisher stage and the overall stage. Feed intake was significantly (p<0.05) higher in supplemented groups and higher when fed in feed as compared with water during all stages. But feed conversion efficiency was significantly improved in non-supplemented groups compared to supplemented ones in finisher and overall stage. The digestibility of gross energy and ether extract was significantly (p<0.05) higher during starter phase in supplemented, given in feed, and at higher levels as compared with non-supplemented, given in water, and at lower levels, respectively. The bone resistance was significantly (p<0.05) higher in supplemented, supplied in feed groups as compared with their counterparts. Except breast meat, the dressing percentage and abdominal fat were also higher in supplemented group and the dressing percentage was significantly (p<0.05) higher in VC supplemented in feed as to water, but no effect of supplementation was noticed on meat color when compared between the methods of feeding (feed vs. water). The levels of VC in plasma and liver increased linearly, as the level of supplementation both in feed and water increased and it was significantly (p<0.05) higher in feed group as compared with water group. It can be concluded that, retention and availability of vitamin C in feed was higher than those in water, and supplementation of VC during summer was beneficial for poultry.

Background: Acute lymphoblastic leukemia (ALL) is most common in childhood. Inhibin (a non-steroidal glycoprotein hormone of gonadal origin) can be used as marker of fertility. The current study was conducted to evaluate inhibin levels in ALL patients and to estimate its correlation with some antioxidants in these in comparison with control subjects. Materials and Methods: This study was conducted on sixty patients with ALL and thirty children as controls. Fasting blood samples were taken from each subject and analyzed for haemoglobin, serum protein, vitamin E and C, in addition to glutathione and inhibin. Results: The results of the study showed highly significant decreases (p<0.001) in haemoglobin, glutathione and inhibin levels with significant decreases (p<0.05) in serum protein and vitamin E levels for patients group in comparison with controls while there was no significant differences in vitamin C. Moreover, there were significant correlations between inhibin levels and serum protein, glutathione and both vitamins (E and C) in the ALL patient group (r= 0.81, 0.80, 0.77 and 0.69, respectively). Conclusions: The present results indicated infertility in patients with ALL demonstrated by low inhibin level as a consequence of abnormality in anti-oxidative metabolism due to the cancer process. So, it can be suggested the need for routine measurement of inhibin for leukemic patients to estimate the action of hormones of gonadal origin.

기능성 성분이 향상된 토마토 품종 개발을 위해서는 성분 정량분석법과 토마토 유전자원 간 대사성분 변이에 대한 정보의 확보가 필요하다. 본 연구에서는 토마토 유전자원23개 계통과 12개 상용 F₁ 품종을 이용하여 수용성 비타민 7종(vitamin C, B1, B2, B3, B5, B6, B9)과 폴리페놀계 성분 5종(quercetin, rutin, kaempferol, myricetin, and naringenin chalcone)에 대한 함량을 비교 분석 하였다. HPLC와 LC-MS 분석 결과, 수용성 비타민과 폴리페놀계의 주요 성분으로 vitamin C와 naringenin chalcone이 각각 검출되었으며 품종 간 높은 수준의 함량 변이가 존재함을 알 수 있었다. 반면에 vitamin B1, quercetin 과 kaempferol은 전 품종에 있어 함량이 가장 낮았다. 대사성분 함량과 토마토 과실특성 간 상관관계에 있어 서 과크기(과중)와 높은 유의성이 관찰되었는데 대부분의 성분에 있어 방울토마토 품종이 완숙용 토마토 품종보다 높은 함량을 보였다. 하지만 naringenin chalcone을 제외하고 대사성분과 과색 간의 상관관계는 뚜렷하게 나타나지 않았다. 본 결과는 토마토 육종과정에 활용될 수 있는 효율적인 대사성분 정량분석법을 제시할 뿐만 아니라 기능성 성분 고함량 육종소재 선발에 중요한 정보를 제공한다.

Vitamin K intake has been reported as an essential factor for bone formation. The current study was conducted under the hypothesis that insufficient vitamin K intake would affect inflammatory markers and bone mineral density in young adult women. The study was a cross-sectional design that included 75 women in their 20s. Physical assessments, bone mineral density measurements, 24-hr dietary recalls, and biochemical assessments for high sensitivity C-reactive protein (hs-CRP) and percentages of undercarboxylated osteocalcin (%ucOC) were performed. An analysis of vitamin K nutritional status was performed comparing first, second, and third tertiles of intake based on %ucOC in plasma. Vitamin K intake levels in the first, second, and third tertiles were $94.88{\pm}51.48\;{\mu}g$, $73.85{\pm}45.15\;{\mu}g$, and $62.58{\pm}39.92\;{\mu}g$, respectively (P < 0.05). The T-scores of the first and third tertiles were 1.06 and -0.03, respectively, indicating that bone mineral density was significantly lower in the group with lower vitamin K intake (P < 0.05). There was a tendency for different serum hs-CRP concentrations between the first ($0.04{\pm}0.02$) and third tertiles ($0.11{\pm}0.18$), however this was not statistically significant. Regression analysis was performed to identify the correlations between vitamin K nutritional status, inflammatory markers, and bone mineral density after adjusting for age and BMI. Serum hs-CRP concentrations were positively correlated with vitamin K deficiency status (P < 0.05). And bone mineral density, which was represented by speed, was negatively correlated with vitamin K deficiency status (P < 0.05). In conclusion, status of vitamin K affects inflammatory status and bone formation. Therefore, sufficient intake of vitamin K is required to secure peak bone mass in young adult women.

Purposes: This study was done to identify factors associated with uncontrolled hemoglobin A1c among patient with diabetes mellitus. Method: The sample was 412 Koreans with diagnosed diabetes aged 40 years or older who participated in the Fifth Korea Health and Nutrition Examination survey, which was a nationwide, cross-sectional survey. Data was analyzed using logistic regression. Uncontrolled hemoglobin A1c rate was 55%. Results: There was a difference between controlled and uncontrolled group in hemoglobin A1c as follows: duration of diabetes, BMI(Body Mass Index), hypertriglyceridemia, vitamin D, sleep duration. After adjusting for confounding factor, longer duration of diabetes (>7 years vs. ${\leq}7$)(Adjusted OR=2.277, 95% CI [1.277-4.060]), presence of hypertriglyceridemia (Adjusted OR=4.019, 95% CI [1.871-8.634]), lower vitamin D level (<20ng/mL vs. ${\geq}20$)(Adjusted OR=2.487, 95% CI[1.411-4.381]), longer sleep duration (6-8 hours vs >8 hours)(Adjusted OR=6.831, 95% CI [1.877-24.855]) were significantly associated with increased odds of uncontrolled hemoglobin A1c. Conclusions: Results show that duration of diabetes, hypertriglyceridemia, vitamin D and sleep duration are significantly related to hemoglobin A1c. Therefore, considering these factors it would be helpful to develop strategies to improve blood glucose control in patients with diabetes.

This study was performed to determine changes in mutagenicity and biogenic amine concentrations in sausages fermented with six different starter cultures treated with vitamins C and E. Six different types of fermented sausages with different combination of starter cultures were manufactured. T1, Pediococcus acidilactici; T2, P. pentosaceus and Staphylococcus carnosus; T3, S. carnosus, S. xylosus, Debaryomyces hansenii, Lactobacillus curvatus, and P. pentosaceus; T4, S. carnosus and L. sakei; T5, S. xylosus and L. plantarum; and T6, Penicillium nalgiovensis. After treatment with vitamins C and E in fermented sausages, changes in mutagenicity and biogenic amine concentrations were measured. The sausages fermented with Staphylococcus xylosus and Lactobacillus plantarum starter cultures showed the most effective antimutagenic activity (p<0.05). The mutagenicity was further decreased in the sausages treated with vitamins C and E (p<0.05), regardless of the starter cultures. The use of Pediococcus acidilactici, S. xylosus, L. plantarum, and Penicillium nalgiovensis as starter cultures was effective in decreasing biogenic amine concentrations (p<0.05). In addition, vitamin E was more effective in decreasing the biogenic amine concentrations than vitamin C. In conclusion, we recommend the use of S. xylosus and L. plantarum as starter cultures, in addition to the use of vitamins C and E, to reduce the potential risk of meat mutagens in fermented sausages.
