Flow injection spectrophotometric determination of vitamin E in pharmaceuticals,milk powder and blood serum using potassium ferricyanide-Fe(Ⅲ) detection system

A simple and sensitive flow injection spectrophotometric method is reported for the determination of vitamin E using potassium ferricyanide-Fe(Ⅲ) detection system.In the presence of vitamin E,Fe(Ⅲ)/ferricyanide reduces.The in situ reduced ions are then reacted with unreduced portion of ferricyanide/Fe(Ⅲ) to make soluble Prussian blue,which is monitored at absorption wavelength of 735 nm.Linear calibration graph was obtained in the concentration range of 0.1-40μg mL^(-1).The relative standard deviations (n=4) were in the range of 1.1-3.6%,with limits of detection(3 s blank) of 0.04μg mL^(-1).The proposed method allowed 12 injections h^(-1).The method is applied to determine vitamin E in pharmaceuticals,infant milk and blood serum samples using hexane extraction with the recoveries in the range of 93±3 to 97.5±4%.The method is validated using certified reference materials SRM 968c for blood serum samples.

Effect of Vitamin D Supplementation on Intracytoplasmic Sperm Injection Outcomes: A Randomized Double-Blinded Placebo-Controlled Trial

OBJECTIVE: To assess the effect of vitamin D supplementation on enhancement of embryos implantation rates in intracytoplasmic sperm injection procedures. STUDY DESIGN: A randomized double-blinded controlled trial. SETTING: Assisted Reproduction Unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt. DURATION: From December 1st 2017 to the end of October 2018. SUBJECTS and METHDS: Eighty infertile couples that underwent ICSI procedure were entrapped in this study.

RESULTS: There was a significantly increased embryo implantation rates (53.2% in vitamin D group versus 46.7% in placebo group), there was a mild statistically significant difference in the clinical pregnancy rates (45.9% in vitamin D group versus 39.4% in placebo group) with p-value < 0.05 and there was an improvement in ongoing pregnancy rate as there was a mild statistically significant difference in first trimester miscarriage rates (12.5% in vitamin D group versus 17.5% in placebo group) with p value CONCLUSIONS: Vitamin D supplementation could improve embryos implantation rates and rate of ongoing pregnancy by decline in the first trimester miscarriage rate.

Clinical Study of Vitamin K_3 Acupoint Injection In Treating Pelvic Pain

Pelvic pain is one of the most common symptoms in gynecologic outpatients. Primary dysmenorrhea, acute or chronic pelvic inflammatory disease, endometriosis, post-operational pelvic adhesion, blood stagnation of pelvic vein, etc. , are mentioned as the often encountered causes of pelvic pain. It has been reported in the recent ten or more years that intramuscular injection of vitamin K3 (Vit K3) could relieve pain induced by smooth muscle spasm. In order to evaluate the effect of Vit K3 administered by acupoint injection in relieving pelvic pain, 180 patients were treated and observed from April 1997 to April 1999 in our hospital, and good therapeutic effect was obtained. It was reported as follows.

Determination of Vitamin B_1 in Pharmaceutical Preparations by Flow-injection Analysis with Biamperometric Detection

A new electrochemical method for the on-line determination of vitamin B1 is presented. Based on dead-stop endpoint biamperometry by using two platinum foil electrodes with an applied potential difference of 150 mV, vitamin B1 can be oxidized by hexacyanoferrate （ Ⅲ ） in a sodium hydroxide medium via a reversible indicating couple Fe（ CN）6^4- /Fe（CN）6^3- The cell current is linear with the concentration of vitamin B1 in the concentration range of 4. 0 × 10^-6-1.0 × 10^ -3 mol/L with a detection limit of 8.0 ×10 ^-7 mol/L（0. 27 μg/mL）. Most familiar excipients, ions and vitamins do not interfere with the determination of vitamin B1. The method displays the advantages of simplicity, high efficiency（ 180 samples/h）, and high selectivity, and is suitable for the determination of vitamin B1 in pharmaceutical preparations.

Conclusion:The fat-soluble vitamins combined with antibiotic treatment of acute infantile mycoplasma pneumoniae infection can inhibit inflammation and oxidative stress, and improve lung function.

Evaluation of the general conditions and inflammatory response of antibiotics combined with fat-soluble vitamin therapy for pediatric pneumonia

Objective: To evaluate the general conditions and inflammatory response of antibiotics combined with fat-soluble vitamin therapy for pediatric pneumonia. Methods: A total of 350 children with pneumonia who were treated in our hospital between January 2014 and January 2017 were collected and divided into control group and observation group according to the random number table, 175 cases in each group. Control group received azithromycin therapy, and observation group received azithromycin combined with fat-soluble vitamin therapy. The differences in the systemic and inflammatory responses before and after treatment were compared between the two groups of patients. Results: Before treatment, differences in blood routine index levels as well as serum contents of oxidative stress indexes and inflammatory factors were not statistically significant between two groups of patients. After treatment, white blood cell count, neutrophil ratio as well as serum CRP, PCT, IL-6 and TNF-α contents of both groups were lower than those before treatment while lymphocyte ratio as well as serum IgA, IgG and IgM contents were higher than those before treatment, and white blood cell count, neutrophil ratio as well as serum CRP, PCT, IL-6 and TNF-α contents of observation group after treatment were lower than those of control group while lymphocyte ratio as well as serum IgA, IgG and IgM contents was higher than those of control group. Conclusion:Antibiotics combined with fat-soluble vitamin therapy for pediatric pneumonia can effectively optimize the patient's general conditions and reduce the inflammatory response.
