Allium jesdianum Extract Induces Oxidative Stress and Necroptosis in Human Colorectal Cancer (HT-29) Cell Line

Abstract This study aimed to evaluate the toxic impact of hydro-alcoholic Allium jesdianum extract (AJE) on the growth of HT-29 human colorectal cancer cell line. Phytochemical analysis using gas chromatography and mass spectroscopy (GCMS) was done to determine the bioactive components of AJE. HT-29 cells exposed to 0 (control), 25, 50, and 100 ��g/mL of AJE for 48 hours. Cell survival, colony numbers, flow cytometry, oxidative stress, and gene expression were examined to evaluate the toxic impacts of the AJE. Twelve different phyto-constituents with peak areas were determined by the GCMS analysis. The major compounds were Allicin and α-Pinene. AJE considerably reduced the viability and colony numbers of the HT-29 cells. The AJE concentration-dependently increased necrosis, but not apoptosis in the HT-29 cells. AJE upregulated the expression of necroptosis-associated genes including RIPK1, RIPK3, and MLKL in a concentration-dependent manner. AJE also dose-dependently enhanced MDA contents and reactive oxygen species (ROS) level and diminished antioxidant enzyme level in the HT-29 cells. These data collectively indicated that AJE prevented the growth of the HT-29 cells by inducing oxidative stress, and activation necroptosis signaling pathways.

Initial clinical experience and follow-up outcomes of treatment for ureteroileal anastomotic stricture with Allium coated metal ureteral stent / 北京大学学报(医学版)

OBJECTIVE@#To summarize the initial clinical experience and follow-up results of the treatment for ureteroileal anastomotic stricture after radical cystectomy with Allium coated metal ureteral stent.@*METHODS@#From September 2018 to September 2019, 8 patients with ureteroileal anastomotic stricture after radical cystectomy underwent Allium ureteral stent insertion in Peking University People's Hospital and People's Hospital of Daxing District. The preoperative renal pelvis width under ultrasound was collected to evaluate the postoperative hydronephrosis, creatinine and urea nitrogen (BUN) before and after surgery, perioperative infection, and stent-related complications. The serum creatinine and BUN, renal pelvis width under ultrasound, urography and abdominal plain film (KUB) were reviewed at the end of 1, 3, and 6 months and annually postoperatively to observe the stent position and morphology. The long-term stent patency rate, complication rate, renal function and hydronephrosis were followed up and analyzed. The t-test or rank-sum test was used to compare the measurement data of the matched sample from the preoperative to the last follow-up.@*RESULTS@#In the study, 6 cases (7 sides) were ureteral ileal conduit stricture, and 2 cases (3 sides) ureteral orthotopic neobladder stricture. Before surgery, 5 patients underwent long-term indwelling of a single J ureteral stent, with an average indwelling time of (20.6±8.8) months and an average replacement frequency of (3.6±1.3) months/time. The mean width of renal pelvis was (26.5±9.1) mm on preoperative renal ultrasonography. Among them, 6 patients were successfully indwelled with Allium coated metal ureteral stent by retrograde approach, and 2 patients by combination of double-endoscopy and ante-retrograde approach. No surgery-related complications during perioperative period were observed. The mean follow-up period was 9.8 months and Allium stent and ureter remained unobstructed in all the patients at the last follow-up without replacement or removal. Compared with preoperative data, the mean width of renal pelvis and mean blood urea nitrogen (BUN) in the last follow-up period were significantly reduced [(26.5±9.1) mm vs. (13.4±2.5) mm, P=0.008; (11.6±2.3) mmol/L vs. (10.2±2.2) mmol/L, P=0.017], however, there were no significant differences in the average serum creatinine or hemoglobin (P>0.05). Ureteroileal anastomotic re-stricture and other stent-related complications were not observed in all the patients by antegrade urography.@*CONCLUSION@#Allium coated metal ureteral stent could be used for the treatment for ureteroileal anastomotic stricture, which could maintain relatively long-term patency rate and protect renal function. The indwelling time was longer and it could improve quality of life of patients.

Different effects of heating and freezing treatments on the antioxidant properties of broccoli, cauliflower, garlic and onion. An experimental in vitro study

ABSTRACT BACKGROUND: Vegetables have some beneficial effects on human health due to their antioxidant compounds, like polyphenols. Cooking leads to many physical and chemical changes to plant structure that can alter the phytochemical compounds of vegetables. OBJECTIVES: To investigate the effects of heat treatment and freezing on the antioxidant properties of garlic, onion, broccoli and cauliflower. DESIGN AND SETTING: Experimental in vitro study in a university laboratory. METHODS: Fresh broccoli (Brassica oleracea var. italica), cauliflower (Brassica oleracea var. botrytis), garlic (Allium sativum) and onion (Allium cepa) were obtained from a local store. These vegetables were divided into three treatment groups: raw, heated and frozen. The heat treatment consisted of heating them in a drying oven at 150 °C for 20 minutes. The freezing treatment consisted of keeping them frozen at -20 °C until analysis. The total phenolic content, antioxidant activity and malondialdehyde levels of the vegetables were measured using the Folin-Ciocalteu phenol reagent, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and thiobarbituric acid reactive substances, respectively. RESULTS: Heat treatment had deleterious effects on the antioxidant properties of onion and garlic; and it decreased the antioxidant activity of broccoli. Freezing improved the antioxidant activity of broccoli and garlic, but had detrimental effects for cauliflower and onion. CONCLUSIONS: Heat treatment and freezing exhibit different effects on the antioxidant properties of broccoli, cauliflower, garlic and onion. Convenient cooking and storage patterns should be identified for each vegetable, to obtain the best nutritional benefit from the antioxidant compounds of vegetables.

Ethanol extract of Allium fistulosum inhibits development of non-alcoholic fatty liver disease

BACKGROUND/OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease and is closely associated with metabolic syndrome. In the present study, we observed the effect of ethanol extract of Allium fistulosum (EAF) on NAFLD and have suggested the possibility of using EAF as a natural product for application in the development of a treatment for NAFLD. MATERIALS/METHODS: The preventive effect on hepatic lipid accumulation was estimated by using an oleic acid (OA)-induced NAFLD model in vitro and a Western diet (high-fat high-sucrose; WD)-induced obese mouse model. Animals were divided into three groups (n = 7): normal diet group (ND), WD group, and WD plus 1% EAF group. RESULTS: EAF reduced OA-stimulated lipid accumulation in HepG2 cells in the absence of cellular cytotoxicity and significantly blocked transcriptional activation of sterol regulatory element-binding protein 1 and fatty acid synthase genes. Subsequently, we investigated these effects in vivo in mice fed either ND or WD in the presence or absence of EAF supplementation. In comparison to the ND controls, the WD-fed mice exhibited increases in body weight, liver weight, epididymal fat weight, and accumulation of fat in hepatocytes, and these effects were significantly attenuated by EAF supplementation. CONCLUSIONS: Allium fistulosum attenuates the development of NAFLD, and EAF elicits anti-lipogenic activity in liver. Therefore, EAF represents a promising candidate for use in the development of novel therapeutic drugs or drug combinations for the prevention and treatment of NAFLD.

Anti-Helicobacter pylori activity and inhibition of gastritis by Allium hookeri extract / 한국실험동물학회지

Allium hookeri is widely consumed plant as a vegetable and herbal medicine in southeastern Asia. Allium hookeri has been reported antioxidant, improvement of bone health and antidiabetic effects. In the present study, we investigated the potential inhibitory effect of Allium hookeri extract (AHE) on Helicobacter pylori. The in vitro anti-bacterial activities of AHE were determined by disk agar diffusion method. Also, the inhibition effect of the AHE on H. pylori infection was investigated using a mouse model. H. pylori colonization was confirmed by rapid urease tests, as described previously. Mucosal damage was evaluated grossly and histologically according to previously described criteria. As the results of the disk agar diffusion assay, CLR, AMX and MTZ inhibited the bacterial growth with inhibition zone of 19.2, 15.2 and 7.5 mm, respectively. AHE 100 µg/mL showed an inhibition zone value of 20.6 mm. Rapid urease tests of the mice stomachs demonstrated a significant reduction in H. pylori colonization. In addition to the therapeutic effect against H. pylori infection, the AHE reduced mucosal inflammation and epithelial damages in the stomach of H. pylori-infected mice. These results demonstrate that the AHE successfully cured an H. pylori infection and treated the H. pylori infection. This AHE could be a promising treatment for patients with gastric complaints including gastritis caused by H. pylori.

Degradation of textile dyes by cyanobacteria

Abstract Dyes are recalcitrant compounds that resist conventional biological treatments. The degradation of three textile dyes (Indigo, RBBR and Sulphur Black), and the dye-containing liquid effluent and solid waste from the Municipal Treatment Station, Americana, São Paulo, Brazil, by the cyanobacteria Anabaena flos-aquae UTCC64, Phormidium autumnale UTEX1580 and Synechococcus sp. PCC7942 was evaluated. The dye degradation efficiency of the cyanobacteria was compared with anaerobic and anaerobic-aerobic systems in terms of discolouration and toxicity evaluations. The discoloration was evaluated by absorption spectroscopy. Toxicity was measured using the organisms Hydra attenuata, the alga Selenastrum capricornutum and lettuce seeds. The three cyanobacteria showed the potential to remediate textile effluent by removing the colour and reducing the toxicity. However, the growth of cyanobacteria on sludge was slow and discoloration was not efficient. The cyanobacteria P. autumnale UTEX1580 was the only strain that completely degraded the indigo dye. An evaluation of the mutagenicity potential was performed by use of the micronucleus assay using Allium sp. No mutagenicity was observed after the treatment. Two metabolites were produced during the degradation, anthranilic acid and isatin, but toxicity did not increase after the treatment. The cyanobacteria showed the ability to degrade the dyes present in a textile effluent; therefore, they can be used in a tertiary treatment of effluents with recalcitrant compounds.

Protective Effect of Allium tuberosum Extract on Vascular Inflammation in Tumor Necrosis Factor-α-induced Human Vascular Endothelial Cells

BACKGROUND: Endothelial adhesion molecule expression induced by pro-inflammatory cytokine plays an important role in vascular endothelial cell injury, leading to vascular disease. Allium tuberosum (AT), which is used as a functional food, has a thrombolytic effect. It contains vitamin A, vitamin C, carbohydrate, calcium, iron, and phosphorus. There are many carotenes that turn into vitamin A in the body. Also, it helps blood circulation and stimulates metabolism. The purpose of the this study was to estimate the anti-inflammatory effects of the AT extract. METHODS: Human vascular endothelial cells were pre-treated with 100 μg/mL AT extract for 30 minutes and subsequently co-treated with TNF-α (10 ng/mL) and AT extract (100 μg/mL) for 1, 4, and 6 hours. After treatment, the cells were lysed and used for quantitative reverse transcription PCR, Western blot analysis, and monocyte adhesion assay. RESULTS: We examined the effect of the AT extract on inflammatory gene expression in TNF-α-induced human umbilical vein endothelial cells (HUVECs). The extract reduced the expression levels of mRNA and protein of intercellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 in TNF-α-stimulated HUVECs. It also inhibited the TNF-α-induced phosphorylation of the NF-κB p65 subunit and degradation of IκBα. Furthermore, the AT extract prevented the increased adhesion capacity of monocyte to TNF-α-stimulated vascular endothelial cells by reducing ICAM-1 and VCAM-1 expression. CONCLUSIONS: The AT extract has preventive and anti-inflammatory effect against vascular disease and has potential for supporting prevention against the early process of atherosclerosis.

The volatile oils, nitrogenous compounds, and steroidal saponins are the major beneficial compounds. Among them, steroidal saponins are considered as the characteristic constituents. In this review, the current information concerning the phytochemistry and pharmacology of Allii Macrostemonis Bulbus is summarized comprehensively. In addition, several research future perspectives are presented, especially the mechanism of bioactive components and fraction from the bulbs of Allium macrostemon and Allium chinense.

Associations between Dietary Allium Vegetables and Risk of Breast Cancer: A Hospital-Based Matched Case-Control Study / 한국유방암학회지

PURPOSE: The protective effect of Allium vegetables against carcinogenesis has been reported in experimental studies particularly focusing on the gut. Therefore, we conducted a hospital-based matched case-control study to explore the association between dietary Allium consumption and risk of breast cancer among Iranian women in northwest Iran. METHODS: A validated, quantitative, food frequency questionnaire was completed in 285 women (aged 25–65 years old) newly diagnosed with histopathologically confirmed breast cancer (grade II, III or clinical stage II, III) in Tabriz, northwest Iran, and the completed questionnaires were included in an age- and regional-matched hospital based-control study. The odds ratios (ORs) and 95% confidence intervals (95% CI) were estimated using conditional logistic regression models. RESULTS: Multivariate analysis showed that there was a negative association between the consumption of raw onion and risk of breast cancer after adjustment for covariates (OR, 0.63; 95% CI, 0.40–1.00); however, this association was insignificant. On the other hand, there was a positive association between consumption of cooked onion and risk of breast cancer, after adjustment for covariates (OR, 1.54; 95% CI, 1.02–2.32). However, reduced risk of breast cancer was associated with higher consumption of garlic and leek with adjusted ORs of 0.41 (95% CI, 0.20–0.83) and 0.28 (95% CI, 0.15–0.51), respectively. CONCLUSION: Our findings suggest that high consumption of certain Allium vegetables, in particular garlic and leek, may reduce the risk of breast cancer, while high consumption of cooked onion may be associated with an increased risk of breast cancer.

Characterization and Pathogenicity of Alternaria vanuatuensis, a New Record from Allium Plants in Korea and China

Alternaria from different Allium plants was characterized by multilocus sequence analysis. Based on sequences of the beta-tubulin (BT2b), the Alternaria allergen a1 (Alt a1), and the RNA polymerase II second largest subunit (RPB2) genes and phylogenetic data analysis, isolates were divided into two groups. The two groups were identical to representative isolates of A. porri (EGS48-147) and A. vanuatuensis (EGS45-018). The conidial characteristics and pathogenicity of A. vanuatuensis also well supported the molecular characteristics. This is the first record of A. vanuatuensis E. G. Simmons & C. F. Hill from Korea and China.

Aqueous extract of Allium sativum L bulbs offer nephroprotection by attenuating vascular endothelial growth factor and extracellular signal-regulated kinase-1 expression in diabetic rats.

To investigate the nephroprotective effect of garlic and elucidate the mechanism by which it prevents the progression of diabetic nephropathy in diabetic rats, diabetes was induced by a single ip injection of streptozotocin (45 mg/kg body weight). Garlic extract (500 mg/kg body weight) and aminoguanidine (1 g/L) were supplemented in the treatment groups. Histopathological examination using H&E, PAS staining and the immunohistochemical analysis of vascular endothelial growth factor (VEGF) and extracellular signal-regulated kinase-1 (ERK-1) expression were performed on kidney sections at the end of 12 weeks. Significant change in both, the urine and serum biochemistry confirmed kidney damage in diabetic animals which was further confirmed by the histological changes such as mesangial expansion, glomerular basement membrane thickening, glycosuria and proteinuria. However, the diabetic animals treated with garlic extract showed a significant change in urine and serum biochemical parameters such as albumin, urea nitrogen and creatinine compared to that of diabetic rats. Further, the garlic supplemented diabetic rats showed a significant decrease in the expression of VEGF and ERK-1 compared to diabetic rats, attenuating mesangial expansion and glomerulosclerosis. Thus, garlic extract rendered nephroprotection in diabetic rats.

Evaluación del potencial mutagénico de biocidas (vertimec y pentacloro) sobre cebolla / Evaluation of the mutagenic potential of biocides (vertimec and pentachloro) on onion

El uso de biocidas es una constante en el campo agronómico, el daño ocasionado a los cultivos y por consiguiente el gran potencial de daño para los consumidores es conocido, sin embargo su uso sigue en marcha. Por ello se realizaron pruebas citogenéticas para la observación de aberraciones cromosómicas en Allium cepa, usando muestras de raíces de plantas expuestas y no expuestas a biocídas. Los tratamientos se realizaron con el objetivo de comparar el grado de afectación de los biocídas sobre la mitosis y la ocurrencia de mutaciones cromosómicas. El ANOVA para los datos de desarrollo radicular al finalizar la experimentación, mostraron un CV de 9.88, se observo diferencias significativas entre el control y los tratamientos, los porcentajes de inhibición llegaron a tener valores máximos de 84.2% para vertimec X8 y 76.5% para pentacloro X8, y valores mínimos de 38.2% para vertimec X0.5 y 43.8% para pentacloro 0.5 X. El índice mitótico fue mayor para el control (0.193) y menores para el tratamiento con menor desarrollo radicular, vertimec X8 (0.021) y pentacloro X8 (0.028). Las pruebas citogenéticas mostraron la ocurrencia de anomalías en el ciclo celular siendo la más frecuente la C-mitosis. Se puede concluir que el test Allium es un buen indicador de citotoxicidad y genotoxicidad. Los biocidas ocasionan cambios en la estructura genómica de un cultivo, estos cambios podrían acumularse y ocasionar cambios de expresión génica, pudiendo dañar regiones de interés agronómico para una especie y afectar su estabilidad genética.

Use of biocides is a constant in the agronomic field, the damage to crops and therefore the potential for harm to consumers is known, however its use is ongoing. Therefore, tests were performed to observe cytogenetic aberrations in Allium cepa using plant root samples exposed and not exposed to biocides. Treatments were performed in order to compare the degree of impact of biocides on mitosis and the occurrence of chromosomal mutations. The ANOVA for root development data at the end of the experiment showed a CV of 9.88, significant differences was observed between control and treatments; the inhibition percentages have reached maximum values of 84.2% for Vertimec X8 and 76.5% for pentachloro X8, and minimum values of 38.2% for Vertimec X0.5 and 43.8% for pentachloro X0.5. The mitotic index was higher for control (0.193) and lower for treatment with less developed root Vertimec X8 (0.021) and pentachloro X8 (0.028). Tests showed the occurrence of cytogenetic abnormalities in the cell cycle being the most frequent C-mitosis. It can be concluded that the Allium test is a good indicator of cytotoxicity and genotoxicity. Biocides cause changes in the genomic structure of crops; these changes may accumulate and cause gene expression changes, can damage agronomic interest regions for a species and affect their genetic stability.

Hypoglycemic effects of three medicinal plants in experimental diabetes: inhibition of rat intestinal alpha -glucosidase and enhanced pancreatic insulin and cardiac glut-4 mRNAs expression

Garlic [Allium sativum L., Alliaceae], Persian shallot [Allium ascalonicum L., Alliaceae] and Sage [Salvia offcinalis L., Lamiaceae] are believed to have hypoglycemic properties and have been used traditionally as antidiabetic herbal medicines in Iran. In this study, diabetes was induced by subcutaneous injection of alloxan monohydrate [100 mg kg[-1]] to male Wistar rats. Antidiabetic effects of methanolic extracts of the above mentioned three plants on alloxan-diabetic rats was investigated in comparison with the effects of antidiabetic drugs such as acarbose, glibenclamide and metformin by measuring postprandial blood glucose [PBG], oral glucose tolerance test [OGTT], inhibition of rat intestinal alpha -glucosidase enzymes activities and pancreatic Insulin and cardiac Glut-4 mRNAs expression. In short term period, hypoglycemic effects of A. sativum and A. ascalonicum showed significant reduction of PBG similar to glibenclamide [5 mg kg[-1] bw] while S. offcinalis significantly reduced PBG similar to acarbose [20 mg kg[-1] bw]. After 3 weeks of treatment by methanolic plant extracts, significant chronic decrease in the PBG was observed similar to metformin [100 mg kg[-1] bw]. For OGTT, S. offcinalis reduced PBG in a similar way as acarbose [20 mg kg[-1] bw]. Intestinal sucrase and maltase activities were inhibited significantly by A. sativum, A. ascalonicum and S. offcinalis. In addition, we observed increased expression of Insulin and Glut-4 genes in diabetic rats treated with these plants extracts. Up regulation of Insulin and Glut-4 genes expression and inhibition of alpha -glucosidaseactivities are the two mechanisms that play a considerable role in hypoglycemic action of garlic, shallot and sage

Two Cases of Poisoning with Veratrum Maackii

Veratrum alkaloids in Veratrum maackii may cause significant gastrointestinal symptoms, bradycardia, hypotension, and arrythmia. We experienced successful outcomes in two patients who were victims of poisoning due to ingestion of Veratrum maackii, which was mistaken for Allium victorialis var. platyphyllum. One patient developed hypotension and prolongation of QT interval in electronicardiogram (ECG) and was treated with administration of vasopressor and magnesium. The other patient developed bradycardia and was treated with administration of atropine. Both patients were kept under close observation, and received supportive care, and both patients were discharged without any symptoms or complications.

Educational attainment and differences in fruit and vegetable consumption among middle-aged adults in the Korean National Health and Nutrition Examination Survey IV

We investigated whether socioeconomic differences affect fruit and vegetable (FV) consumption with respect to total intake and intake of various FV subgroups. Our study included 6667 adults aged 40-64 years who completed a dietary survey in the fourth Korean NHANES (2007-2009). FV intake was estimated from 24-hour recalls and food frequency questionnaires. Differences in FV consumption related to educational attainment were analyzed according to different nutritional categories of FV. Both men and women in the low-education group had the lowest intake of total FV and total fruits, and women also had the lowest intake of total vegetables. Also lowest in this group was consumption of mushrooms and vegetables (excluding kimchi) among men, and cruciferous and allium vegetables (excluding Chinese cabbage and radish) among women, while kimchi consumption was the highest in this group. Additionally, an association between educational level and intake of citrus fruits was evident among men. Adults in the low-education group consumed less carotene-rich FV, red fruit and/or vegetables, and dark-green leafy vegetables, fewer total vegetable dishes, and fewer types of fruit than in other groups. Men in this group had the lowest intake of yellow/orange fruit and/or vegetables, and women consumed the least folate-rich FV. There is a clear association between educational attainment and FV intake with regard to total intake, and to specific nutrients, bioactive compounds, colors, and variety.

Occurrence of Sclerotium Rot in Allium tuberosum Caused by Sclerotium rolfsii in Korea

In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the scaly stem and leaves. The sclerotia were globoid, 1~3 mm, and white to brown. The optimum temperature for growth and sclerotia formation on potato dextrose agar (PDA) was 30degrees C. The diameter of the hypae ranged from 4 to 8 microm. Clamp connection was observed on PDA medium after 5 days of incubation. Based on the mycological characteristics, internal transcribed spacer sequence analysis, and pathogenicity test, the causal agent was identified as Sclerotium rolfsii Saccardo. This is the first report of sclerotium rot in Chinese chive caused by S. rolfsii in Korea.

Allium species poisoning in dogs and cats: [review]

Dogs and cats are the animals that owners most frequently seek assistance for potential poisonings, and these species are frequently involved with toxicoses due to ingestion of poisonous food. Feeding human foodstuff to pets may prove itself dangerous for their health, similarly to what is observed in Allium species toxicosis. Allium species toxicosis is reported worldwide in several animal species, and the toxic principles present in them causes the transformation of hemoglobin into methemoglobin, consequently resulting in hemolytic anemia with Heinz body formation. The aim of this review is to analyze the clinicopathologic aspects and therapeutic approach of this serious toxicosis of dogs and cats in order to give knowledge to veterinarians about Allium species toxicosis, and subsequently allow them to correctly diagnose this disease when facing it; and to educate pet owners to not feed their animals with Allium-containg food in order to better control this particular life-threatening toxicosis.

Anti-mycobacterial activity of garlic [Allium Sativum] against multi-drug resistant and non-multi-drug resistant Mycobacterium tuberculosis

Emergence of multi-drug resistant [MDR] and extensively drug resistant [XDR] TB throughout the developing world is very disturbing in the present scenario of TB management. There is a fundamental need to explore alternative anti-TB agents. Hence natural plants should be investigated to understand their antimicrobial properties and safety. Garlic [Allium sativum] is one of natural plant which possesses variety of biological properties like anti-tumor, anti-hyperlipedemic and anti-microbial etc. The present study was evaluated for antibacterial activity of garlic against non-MDR and MDR isolates of M. tuberculosis. A total of 20 clinical isolates of MTB including 15 MDR and 5 non-MDR were investigated. Ethanolic extract of garlic was prepared by maceration method. Minimum inhibitory concentration [MIC] was performed by using 7H9 middle brook broth dilution technique. MIC of garlic extract was ranged from 1 to 3 mg/ml; showing inhibitory effects of garlic against both non-MDR and MDR M. tuberculosis isolates. Alternate medicine practices with plant extracts including garlic should be considered to decrease the burden of drug resistance and cost in the management of diseases. The use of garlic against MDR-TB may be of great importance regarding public health
