Objective: Uterine myomas are the most common benign tumors in females. Most myomas are asymptomatic and require no intervention or further investigations; however, almost a third of women with myomas will require a therapy. Treatment options include pharmacological approaches or surgery, and depend on symptomatology, size, number and desire for future pregnancy. Minimally invasive procedures or alternative medical treatments for handling myomas are preferred, when possible, to the radical abdominal surgery. Vitamin D and epigallocatechin gallate (EGCG) recently proved effective in the management of these benign tumors. Our aim was to verify the effect of combined oral vitamin D and EGCG supplementation in symptomatic women with myomas.
Patients And Methods: Symptomatic women with myomas were enrolled in this pilot study and divided in two groups: one group treated daily with two tablets of 25 μg vitamin D + 150 mg EGCG + 5 mg vitamin B6, for 4 months; the other group received no treatment (control), for the same period. Volume, number of myomas as well as severity of symptoms (SS) and quality of life (QoL) were analyzed.
Results: The total myoma volume significantly decreased by 34.7% in the treated group, whereas it increased by 6.9% in the control group. An improvement in the QoL of women treated with vitamin D, EGCG and vitamin B6 was reported along with a reduction of the SS.
Conclusions: The combined supplementation of vitamin D and EGCG seems to be an optimal approach for the management of myomas and correlated symptoms. For the first time, we showed the cooperative effectiveness as a promising and novel treatment for myomas.

Cisplatin (CIS) is a broad-spectrum anticancer drug widely used in the clinic; however, one of its side effects is that it can cause intestinal damage such as loss of appetite, vomiting, and diarrhea in patients. Epigallocatechin gallate (EGCG) is one of the main active substances in green tea, which has the effects of antitumor multiple drug resistance, antioxidation, and antiinflammatory properties. The aim of this study was to explore the protective effect of EGCG on CIS-induced intestinal injury in rats.

(1) Background: Ultraviolet radiation takes part in photoaging and pigmentation disorders on skin. Epigallocatechin gallate (EGCG) is a well-known brightening and photoprotective compound but it faces limitations in terms of stability and solubility. (2) Methods: A more stable and water-soluble glucoside called EGCG-G1 was obtained by enzymatic glucosylation of EGCG.

Effects of phenolic compounds in conjunction with L-cysteine/l-ascorbic acid on the redox state of myoglobin (Mb) and their efficacy to maintain the color and quality of refrigerated longtail tuna (Thunnus tonggol) slices were investigated. Purified metmyoglobin (metMb) and oxymyoglobin (oxyMb) samples were added with epigallocatechin-3-gallate (EGCG) or quercetin individually or in combination with L-cysteine (CT) or L-ascorbic acid (AA) at 4 °C. EGCG in combination with AA (EGCG+AA) and AA alone significantly reduced metMb and increased oxyMb levels (p < 0.

As precursors of disinfection by-products (DBPs), sediment hydrophobic organic compounds (HPOCs) derived from six reservoirs along the Dongjiang River were chlorinated (Cl-WS) and then fractionated into two polar components (hydrophobic organic compounds (Cl-HOCs) and hydrophilic organic compounds (Cl-HICs)) by solid phase extraction. Based on Caco-2 cell exposure study, the genotoxicity of Cl-WS, Cl-HOCs and Cl-HICs was analyzed by reactive oxygen species (ROS) analysis, comet assay and ethoxyresorufin-O-deethylase assay. Protective effects of antioxidants (catalase, vitamin C and epigallocatechin 3-gallate (EGCG)) on genotoxicity of the chlorinated samples were investigated.

Recent studies have shown that epigallocatechin-3-gallate (EGCG), as an effective antioxidant, could attenuate the oxidative damage, inflammation and necrosis in the liver in response to oxidative stress. The present study investigated whether oral administration of EGCG could effectively alleviate the hepatic histopathological changes and oxidative damage in yellow-feathered broilers induced by -butyl hydroperoxide (-BHP). Broilers were exposed to 600 μmol -BHP/kg body weight (BW) to induce oxidative stress by intraperitoneal injection every five days, followed by oral administration of different doses of EGCG (0, 20, 40 and 60 mg/kg BW) and 20 mg vitamin E (VE)/kg BW every day during 5-21 days of age.
