Silymarin compounds were quantified using a LC-MS analysis that was performed on a Water 2695 Alliance (Waters-Micromass, Manchester, UK) coupled with a single quadrupole mass spectrometer ZQ (Waters-Micromass, Manchester, UK). LC-ESI-MS data were collected in the positive and negative modes. Data acquisition and processing were performed with MassLynx 4.0 software (Waters-Micromass, Manchester, UK). The separation was performed at 35 °C on a core-shell column (Kinetex 5 µm XB-C18, 100 Å, LC Column 150 × 4.6 mm, C18 with iso-butyl side chains, and with TMS endcapping, core-shell silica, Phenomenex Le Pecq France). The mobile phase was composed with a mixture of methanol (solvent A) and HPLC grade water (solvent B), both being acidified with 0.05% formic acid. A linear gradient was applied for the mobile phase variation, ranging from a 5:95 (v/v) to 100:0 (v/v) mixture of solvents A and B, respectively, with a flow rate of 1.30 mL/min. The injection volume was 3 µL, the maximum back pressure was 110 bar and the detection was performed at 280 nm. Flavonolignans were identified by comparison with authentic standards (Sigma Aldrich). The limits of detection (LOD) and the limits of quantification (LOQ) were determined based on the signal-to-noise ratio (S:N) of 3:1 and 10:1, respectively.

Silymarin was obtained from the following suppliers: Sigma-Aldrich (SM 1; St. Louis, MO, USA, batch No. BCBJ0393V), Liaoning Senrong Pharmaceuticals (SM 2; Panjin, China, batch No. 120501), INDENA (SM 3; Settala, Italy, batch No. 32621/M5), Panjin Huacheng Pharmaceutical Company (SM 4; with an additive for better solubility in water, Panjin, China, batch No. E5S66), Takeda (SM 5; Konstanz, Germany, Flavobion® coated tablets, batch No. 383036), Panjin Huacheng Pharmaceutical Company (SM 6; supplied in August 2019 without batch No., Panjin, China). Flavobion® coated tablets (25 tablets, 11.360 g) were powdered and subjected to Soxhlet extraction with acetone (450 mL) for 2 h, the extract was evaporated in vacuo to yield the sample SM 5 (126 mg of dry extract). The extract was stored at −80 °C. Standards of silybin A, silybin B, 2,3-cis-silybin A, 2,3-cis-silybin B, 10,11-cis-silybin A, 10,11-cis-silybin A, silychristin A, silychristin B, isosilychristin, silydianin, isosilybin A, isosilybin B, silyhermin, 2,3-dehydrosilybin A, 2,3-dehydrosilybin B, 2,3-dehydrosilychristin A, 2,3-dehydrosilychristin B, 2,3-dehydroisosilybin, and 2,3-dehydrosilydianin were prepared and fully characterized in the Laboratory of Biotransformation, Institute of Microbiology, Prague, CZ [11 (link),21 (link),22 (link),23 (link),24 (link),25 (link)]. Taxifolin was purchased from Amagro (Prague, Czech Republic) and coniferyl alcohol from Sigma-Aldrich (Merck, Kenilworth, NJ, USA). All standard solutions for calibration curves were prepared in dimethyl sulfoxide in volumetric flasks. The silymarin preparations SM 1–SM 6 were also dissolved in dimethyl sulfoxide and their concentrations were 10.3, 6.5, 13.3, 8.3, 15.5, and 23.1 mg/mL, respectively. All substances dissolved in dimethyl sulfoxide were stable during the measurement; no new peaks appeared in repeated measurements even after several weeks. The concentrations of the flavanonol, flavonolignans, and 2,3-dehydroflavonolignans were calculated using seven-point calibration curves.
Silymarin fraction containing concentrated 2,3-dehydroderivatives of flavonolignans was obtained from silymarin (SM 2 preparation) as described previously [23 (link)] using Sephadex LH-20 glass column XK 50 (100 × 5 cm, bead size 25–100 μm, GE Healthcare Life Sciences, Pittsburgh, PA, USA) equipped with a thermostatic jacket (23 °C). Isocratic elution with methanol, flow rate 3 mL/min, volume of each fraction was 30 mL, UV detection at 254 nm, run-time 28 h [23 (link)]. Briefly, 6 g of “silybin free” silymarin (see Appendix B) was loaded onto the column and eluted with methanol to obtain a fraction enriched in 2,3-dehydroderivatives of flavonolignans (typically 0.8 g).
Acetonitrile, methanol, formic acid, dimethyl sulfoxide (Avantor, Radnor, PA, USA), and deionized water were of LC-MS grade.

This experimental study was approved by the local ethics committee for animal
experiments (Dollvet Veterinary Vaccines Biological Substance Drug Production
Industry and Trade Inc. Şanlıurfa, Turkey). The experiments were
conducted on 30 three-month-old Wistar albino rats that ranged in weight from
200 g to 250 g. All the animals were kept under standard conditions and were
treated according to the guidelines of the National Institutes of Health. The
animals were kept in a 12h light/dark cycle (lights were turned on at 6 am). The
animals were deprived of food and water for 12h before surgery. The experiments
were conducted at the Dollvet Laboratory of Experimental Research.
The rats were randomly divided into three experimental groups: sham (n=10),
control (n=10) (I/R), and silymarin (n=10) (I/R-silymarin). They were
anesthetized intraperitoneally with xylazine (10 mg/kg) and ketamine
hydrochloride (50 mg/kg). The abdomens of the animals were shaved and then
cleaned with a povidone-iodine solution, and an abdominal midline incision was
made. In the sham group, only a laparotomy was carried out. In the control
group, a cross clamp was placed on the supraceliac aorta and ischemia was
applied for 45 min; this was followed by reperfusion for 60 min. In the
silymarin group, the cross-clamp was placed on the supraceliac aorta for 45 min,
and this was followed by reperfusion for 60 min. Silymarin was administered
during ischemia at a dose of 200 mg/kg via the intraperitoneal
route[6 (link)]. At the end of the study, blood samples were
obtained from the inferior vena cava of the rats, and heart, lung, liver and
kidney tissues were sampled and placed in formalin for pathological examination.
The blood samples obtained were centrifuged, and plasma was separated and stored
in the freezer at -80°C until biochemical analyses were performed. Silymarin
tablets were obtained from the pharmacy (Sigma-Aldrich, St. Louis, MO, USA). A
silymarin tablet of 85% purity was dissolved with 1% dimethyl sulfoxide before
it was administered.

Designing a randomized clinical trial (RCT) of IO care’s safety and efficacy, and not just a single agent treatment, faces several methodological challenges. First, federally-funded trials of IO care would require FDA approval to conduct research (INDs) for each element of IO care that involves a therapeutic substance (T. versicolor mushroom extract, mistletoe, curcumin, green tea, resveratrol, artemisinin, silymarin and melatonin to mention just a few commonly used IO treatments). Second, an IO RCT would require the development of a single standardized treatment algorithm that could be used as a strict protocol. Most IO clinics do not have strict standards of care or protocol guidelines of the sort needed for a definitive RCT, instead allowing providers to customize care to each individual patient. Third, once such a protocol is developed an estimated effect size for the protocol as a whole will be needed. If IO treatments are synergistic and their combination is more than the sum of their individual effects, this effect size could not be computed based on the effects found in single treatment studies. Estimates for conventional medicine RCTs examining behavioral and nutritional interventions commonly come from epidemiological research studies often conducted using non-randomized study designs and matched comparison groups.
There is also a potentially significant problem for an IO care RCT in patient recruitment. Patients already seeking IO care would be unlikely to enroll in a study with possible randomization to a non-treatment group. Similarly, those not already seeking IO care may be reluctant to sign up for randomization to IO activities they might find burdensome and that are not demonstrated to improve health.
Building strong evidence for efficacy of IO care may likely require RCTs. However, until we know more about the likely effects of IO care, we cannot proceed with RCTs. Therefore, it is appropriate to use other designs to create evidence to support an RCT proposal. For now, prospective outcomes studies using matched comparison women to assess the effects of IO care holistically via a health services approach may be most appropriate. The ethics of using clinical data collected from patients receiving reimbursed healthcare to evaluate those health services has been evaluated favorably. 24 (link)

Except for the control and CLP groups, silymarin (SIGMA S0292-10G) was given to the other groups in 50 mg/kg, 100 mg/kg, and 200 mg/kg doses with a gavage needle and orally. Silymarin serum was applied after being suspended in physiological water. An hour later, CLP was applied to the third, fourth, and fifth groups (Groups 3, 4, and 5). Oral-applied silymarin reaches the highest level in plasma within approximately 2–4 hr and it has a half-life of 6 hr [72 (link)]. The application of anesthetic material for the operation was given an hour before the silymarin operation because it slowed down the absorption of the drug. Only the CLP model was applied to the second group.
CLP is a method used to create septicemia in polymicrobial properties. The animals in the operation groups were anesthetized with xylazine (5 mg/kg) and ketamine hydrochloride (40 mg/kg). The rats were secured on the back, and the infiltration line of the abdomen was wiped twice with povidone-iodine solution, providing the antisepsis. The midline of the abdomen was opened with a 3 cm incision and the cecum was explored. The ligation was applied under the ileocecal valve with silk floss (3/0). The connected section was drilled twice with the standard injector tip measuring 18 gauge and tightened to allow some of the fecal matter to come out. Then, the cecum was placed in the abdomen and the abdomen was closed with the stapler in normal anatomical form.
In the CLP rat model, the perforation was constituted with 13, 16, 18, and 22 caliber injector tips and a 0.5 cm scalpel, and the mortality of the experimental subjects was assessed in the literature [45 (link)]. Therefore, we used an 18-gauge injector to obtain blood and liver tissue in this study before the rats died.
The operated animals were taken into postoperative care for 16 hr. At the end of 16 hr, 15 mg/kg xylazine and 100 mg/kg ketamine were administered intraperitoneally to all subjects. Thus, the reflexes of the anesthetized rats were controlled and an incision was made at the level of the abdominal diaphragm. The animals whose blood samples were taken from their hearts under deep anesthesia were sacrificed by cervical dislocation. Then, the liver tissues of all animals were taken to a solution containing 10% formaldehyde for histopathological and immunohistochemical studies. The blood samples taken were used for biochemical analysis.

We are grateful for the provision of silybin A/B by Dr. David Biedermann, Institute of Microbiology of the Czech Academy of Sciences, in the Laboratory of Biotransformations, Prague. The preparation of silybin from silymarin has been described previously [13 (link)]. Briefly, 200 mg of silymarin (Liaoning Senrong Pharmaceutical Co., Panjin, China) was suspended in 10 mL of methanol. The insoluble silybin was filtered, and the filtrate was collected and applied to a SEPHADEX HL-20 colony (Sigma Aldrich, Schnelldorf, Germany). The isocratic method with a mobile phase of water/methanol/cyanomethane/formic acid in the ratio 2/37/61/0.1 was used. The flow rate of the mobile phase was 1.2 mL/min, and the detection was performed spectrophotometrically at 285 nm SYNERGY HT (Biotek, Winooski, VT, USA). The purity of the obtained silybin (mixture of two diastereoisomers A and B) was 95 %, as determined by HPLC PDA. For further analyses, silybin was dissolved in dimethyl sulfoxide (Sigma Aldrich, Germany) to a 100 mM stock solution, which was subsequently diluted in the appropriate culture media.
