Theca lutein cysts are rare, benign lesions responsible for gross cystic enlargement of both ovaries during pregnancy. This condition is also termed hyperreactio luteinalis. Elevated human chorionic gonadotropin (hCG) levels or states of hCG hypersensitivity seem to promote these changes, which in up to 30% of patients produce clinical signs of hyperandrogenism. Given the self-limiting course of theca lutein cysts, which are subject to spontaneous postpartum resolution, conservative treatment is the mainstay of patient management. Described herein is a rare case of theca lutein cysts with maternal virilization that failed to regress by 9 months after childbirth. Surgical intervention was eventually undertaken, necessitated by adnexal torsion.

Purpose: To evaluate safety, gastrointestinal tolerance, and growth of a new experimental starter formula (NESF) fortified with lutein, prebiotics, probiotics, nucleotides and beta-carotene, fed to infants within the first months of life. Methods: This was a non-randomized, open, uncontrolled study conducted from December 2010 to May 2011. Twenty-three healthy infants aged 10 days to 2 months old were enrolled. Outcomes included gastrointestinal tolerance, physical growth and safety. Prior to the initiation of the trial, the Scientific Research Institute of Nutrition of the Russian Academy of Medical Sciences confirmed that the NESF met all safety and nutritional parameters. Results: NESF was well tolerated. The majority of infants fed this formula passed semi-liquid, yellow or yellow-brown. The mean stool frequency/day was $2.5{\pm}0.4$ on study-day 14 and $1.8{\pm}0.5$ on study-day 28. The mean daily weight gain was $30.9{\pm}3.8$ grams and the mean length gain during the 28 days of follow up was $3.1{\pm}0.8cm$, corresponding to the average physical growth normally seen in the first months of life in Russian infants. Six children left the study: one refused to drink the formula, one left the study as parents changed residence; and one child's parents have recalled their informed consent due to adverse event unrelated to the product. Three infants presented adverse events possibly related to the product (rash; colic and abdominal pain; constipation). Seventeen infants completed the trial. Conclusion: This study demonstrated that lutein-fortified formula is safe, well-tolerated and supported physical growth of evaluated infants.

The purpose of this study was to diagnose nutritional status of vitamin A in female university students. Total of 59 female students in Korea National University of Education, Home Economics Education department were recruited for this study. Retinol and :t major carotenoids in serum($\beta$-carotene, u-carotene, lycopene and lutein) were analyzed by HPLC. The isocratic separation was performed in a $\mu$ Bondapak$^{TM}$ $C_{18}$ stainless steel column with a solvent system of acetonitrile : methanol=85:15. The results of analysis were as follows: The average retinol concentration of 59 female students was 25.9$\mu\textrm{g}$/100$m\ell$. According to biochemical criteria for the assessment of vitamin A status, 18 of them belong to well-nourished and 6 students belong to adequate status. On the other hand, 8 students, 3 freshmen and 5 sophomore, were in critical vitamin A status. Retinol concentrations of junior and senior students were higher than those of freshmen and sophomore (P＜0.001). The average concentrations of serum $\beta$-carotene, lycopene, and lutein were 1.9, 5.4, and 41.4$\mu\textrm{g}$/100$m\ell$, respectively. Serum $\beta$-carotene concentration of senior was significant. higher than those of freshman, sophomore and junior(p＜0.001). Lycopene concentration of freshman was significant. lower than those of the other grades and that of senior was sig, higher than those of the other grades(p＜0.05). Lutein concentrations of junior and senior were significant. higher than those of freshman and sophomore(p＜0.001). The serum $\alpha$-carotene concentrations of the students were too low to analyze.e.

Carotenoids are effective antioxidants that are found in various photosynthetic organisms. Marine microalgae are an advantageous bioresource for carotenoid production because they do not compete with other crops for freshwater and arable land. This study reports a newly isolated Dunaliella strain from the Geumhong Saltpan on Yeongjong Island, West Sea, Korea. The new strain was isolated and classified as Dunaliella salina through phylogenetic analysis and was named the OH214 strain (Deposit ID: KCTC14434BP). The newly isolated strain can survive in a wide range of NaCl concentrations (0.3-5.0 M NaCl), but grows well in 0.6 to 1.5 M NaCl culture medium. Under high-light conditions (500 ± 10 μmol photons m^-2 s^-1), the cells accumulated three times more β-carotene than under low-light conditions (50 ± 5 μmol photons m^-2 s^-1). The cells accumulated 2.5-fold more β-carotene under nitrogen-deficient (1 mM KNO₃) conditions (3.24 ± 0.36 ㎍ 10⁶ cells^-1) than in nitrogen-sufficient conditions (>5 mM KNO₃). The lutein content under nitrogen-deficient conditions (1.73 ± 0.09 ㎍ 10⁶ cells^-1) was more than 24% higher than that under nitrogen-sufficient conditions. Under the optimized culture condition for carotenoid induction using natural seawater, D. salina OH214 strain produced 7.97 ± 0.09 mg g DCW^-1 of β-carotene and 4.65 ± 0.18 mg g DCW^-1 of lutein, respectively. We propose that this new microalga is a promising strain for the simultaneous production of β-carotene and lutein.

Capacity of the analytical/quantitative evaluation techniques to satisfy both qualitative and quantitative considerations for effective extraction of marigold oleoresins/xanthophylls and their potential as anti-mycotic and antioxidant activity was assessed. Accelerated solvent extraction (ASE), Soxhlet extraction (SE), Supercritical fluid extraction (SCFE), Cold extraction (CE), and ultrasonically assisted extraction (USE) techniques were evaluated for extraction of oleoresin/xanthophyll content from Tagetes erecta (Var. Pusa Narangi Genda) with respect to solvent consumption, extraction time, reproducibility, and yield. Followed by the antifungal and antioxidant activity evaluation. The overall yield of Tagetes oleoresin was higher in ASE (64.5 g/kg) followed by SE (57.3 g/kg), USE (50.7 g/kg), SCFE (45.3 g/kg) and CE (31.6 g/kg). The lutein esters represented more than 80% of the constituents. Further, xanthophyll/ lutein content in oleoresin was found to be quite higher in HPLC (r2 = 0.996) analysis than in the AOAC recommended UV spectrophotometer analysis. The oleoresin exhibited moderate antioxidant activity (DPPH assay) and antifungal activity against three phytopathogenic fungi. Based on the various parameters, the reproducibility of ASE was better (0.3-8.0%) than that of SE (0.5-12.9%), SCFE (0.2-9.4%), USE (0.3-12.4%) and CE (0.8-15.3%). ASE with (RSD 1.6%) is preferred being faster, reproducible, uses less solvent, robust and automation allows sequential extraction of the sample in less time.
