The present paper focused on antioxidant and cytotoxicity assessment of crude and total saponin fraction ofChlorophytum borivilianumas an important medicinal plant. In this study, three different antioxidant activities (2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH), ferrous ion chelating (FIC), andβ-carotene bleaching (BCB) activity) of crude extract and total saponin fraction ofC. borivilianumtubers were performed. Crude extract was found to possess higher free radical scavenging activity (ascorbic acid equivalents 2578 ± 111 mg AA/100 g) and bleaching activity (IC50= 0.7 mg mL−1), while total saponin fraction displayed higher ferrous ion chelating (EC50= 1 mg mL−1). Cytotoxicity evaluation of crude extract and total saponin fraction against MCF-7, PC3, and HCT-116 cancer cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) cell viability assay indicated a higher cytotoxicity activity of the crude extract than the total saponin fraction on all cell lines, being most effective and selective on MCF-7 human breast cancer cell line.

Gouty arthritis (GA) is an inflammatory disease caused by the deposition of monosodium urate in the synovial membrane and cartilage due to a high concentration of uric acid in the blood. Dioscorea nipponica Makino is widely used in the clinic to treat GA. Total saponins are its main components and showed an anti-inflammatory effect on GA in a previous study. The mitogen-activated protein kinase (MAPK)-peroxisome proliferator-activated receptor γ (PPARγ) signaling pathway plays a key role during the onset of GA; however, little is known about its potential mechanism. Based on in vitro experiments, this study aims to determine the mechanism of total saponins from Dioscorea nipponica Makino (TDN) in treating GA by regulating the MAPK-PPARγ signaling pathway. Fibroblast-like synoviocytes were divided into 3 groups: the model group, which was given 10 µg/L IL-1β to induce proliferation; TDN group (10 µg/L IL-1β + 100 µg/L TDN); and indomethacin group (10 µg/L IL-1β + 100 µg/L indomethacin). Seventy-two hours after treatment, the real-time PCR method was used to detect the mRNA expression levels of extracellular signal regulated kinase 1/2 (ERK1/2), p-38, c-Jun N-terminal kinase (JNK), IKKα, c-Jun, MAPK phosphatase (MKP), vascular cell adhesion molecule 1 (VCAM1), intercellular adhesion molecule 1 (ICAM1), C-X-C motif chemokine ligand 1 (CXCL1), PPARγ, and Adipor2. The Western blot method was used to detect the protein expression of ERK1/2, p-ERK1/2, p-38, p-P38, JNK, p-JNK, IKKα, p-IKKα, c-Jun, p-c-Jun, MKP, p-MKP, VCAM1, ICAM1, CXCL1, PPARγ, and Adipor2. Compared with the model group, the TDN group displayed significantly increased mRNA expression of c-Jun, MKP, CXCL1, PPARγ, and Adipor2 and significantly decreased mRNA expression of ICAM1. Compared with the model group, the TDN group exhibited significantly increased protein expression of MKP and significantly decreased protein expression of p-ERK1/2, p-38, p-JNK, p-IKKα, p-c-Jun, VCAM1, ICAM1, and PPARγ. Our results indicated that TDN could treat GA by influencing the MAPK-PPARγ signaling pathway.

Gout or Gouty Arthritis is a degenerative disease. Gouty arthritis is a clinical syndrome that is caused by deposition of purine crystals in the tissues, due to levels of uric acid (hyperuricemia) in the extracellular fluid that passes through saturation. The etiology of gout arthritis included age, sex, history of medication, obesity, consumption of purine and alcohol. Aging is an important risk factor for men and women. This study uses an analytical-descriptive approach with cross-sectional design. This study was conducted to obtain a relationship between nutritional status and uric acid levels in the community in the area of ​​Al-Hidayah Islamic Boarding School, Ngawi. This research was conducted in Majasem Village, Kendal District, Ngawi Regency, starting from 7 June - 31 August 2018. The results showed that there was a relationship between nutritional status and uric acid levels in the community in the area of ​​Al-Hidayah Islamic Boarding School, Ngawi (p=0,008). Suggestions for further research are bivariate analysis based on gender, knowledge and attitude to response to diet so that other factors that influence can be seen clearly

Acute gouty arthritis represents an inflammatory response to microcrystals of monosodium urate that precipitate in joint tissues from supersaturated body fluids or are shed from preexisting articular deposits [1]. Gout is a metabolic disease characterized by recurrent episodes of arthritis associated with the presence of monosodium urate crystals in the tissue or synovial fluid during the attack.These forms of crystal-induced arthritis usually affect peripheral joints, including knee, ankle, wrist, and metacarpophalangeal and metatarsophalangeal joints. All of them may be associated with other inflammatory, endocrine diseases [2]. The present study was done to highlight the relationship between increased levels of uric acid and specific laboratory tests in order to possible forecast development of further disease in patients with gouty arthrithis.The present study was done on 34 patients hospitalized in Felix Hospital of Rehabilitation in 2015-2016, with age between 44 and 74, having the main diagnosis of gouty arthritis.We studied the following laboratory tests:urea and other related analysis, like uric acid, creatinine, cholesterol, glutamate pyruvate transaminase and glutamate oxalate transaminase.
