Abstract
Aged garlic, obtained by heating raw garlic (Allium sativum) under high temperature and controlled humidity for a period, possesses a wide range of bioactivities, but its role in ulcerative colitis and its mechanism are not fully elucidated. We investigated the bioactive constituents in aged garlic (AG) and explored the effect of oral AG delivery on DSS-induced murine colitis. The results revealed that the aging process up-regulated anti-oxidative, anti-inflammatory and anti-microbial compounds such as dihydrocaffeic acid, 5-acetylsalicylic acid, verticine, S-allyl-L-cysteine and D-fucose. Oral AG obviously alleviated colitis, reducing colon damage and enhancing anti-oxidative and anti-inflammatory effects. Escherichia coli and Streptococcus equinus dramatically were enriched in the colon of mice with colitis that were strongly associated with Parkinson's disease, bacterial invasion of epithelial cells, aerobactin biosynthesis, and heme biosynthesis, but a distinct AG-mediated alteration in the colon due to increasing abundance of Akkermansia muciniphila, Lactobacillus sp. L-YJ, Bifidobacterium breve, Blautia wexlerae, Desulfomicrobium sp. P100A, and Lentilactobacillus hilgardii was observed. Next, we demonstrated that colonic microbiome reconstruction by oral AG significantly increased the production of short-chain fatty acids such as acetic acid, propionic acid, isobutyric acid, and isovaleric acid. This study provides the first data indicating that oral AG ameliorates colonic inflammation in a gut microbiota-dependent manner. Our findings provide novel insights into the AG-mediated remission of colitis and AG as a functional food for modulating the gut microbiota to prevent and treat colitis.

Anti- Leishmania amazonensis Activity, Cytotoxic Features, and Chemical Profile of Allium sativum (Garlic) Essential Oil. Trop Med Infect Dis 2023; 8:375. [PMID: 37505671 PMCID: PMC10384145 DOI: 10.3390/tropicalmed8070375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 07/15/2023] [Accepted: 07/17/2023] [Indexed: 07/29/2023] Open
Abstract
Human tegumentary leishmaniasis (HTL) is a serious tropical disease caused by Leishmania amazonensis. Developing new leishmanicidal agents can help overcome current treatment challenges, such as drug resistance and toxicity. Essential oils are a source of lipophilic substances with diverse therapeutic properties. This study aimed to determine the anti-L. amazonensis activity, cytotoxicity, and chemical profile of Allium sativum essential oil (ASEO). The effect of ASEO on parasite and mammalian cells viability was evaluated using resazurin and MTT assays, respectively. The oil's effect against intracellular amastigotes was also determined. Transmission electron microscopy was used to assess the ultrastructural changes induced by ASEO. In addition, the chemical constituents of ASEO were identified by gas chromatography-mass spectrometry (GC-MS). The cytotoxic potential was evaluated in vitro and in silico. The oil displayed IC50 of 1.76, 3.46, and 3.77 µg/mL against promastigotes, axenic, and intracellular amastigotes, respectively. Photomicrographs of treated parasites showed plasma membrane disruption, increased lipid bodies, and autophagic-like structures. ASEO chemical profiling revealed 1,2,4,6-tetrathiepane (24.84%) and diallyl disulfide (16.75%) as major components. Computational pharmacokinetics and toxicological analysis of ASEO's major components demonstrated good oral bioavailability and better toxicological endpoints than the reference drugs. Altogether, the results suggest that ASEO could be an alternative drug candidate against HTL.

The possible protective role of melatonin versus garlic on monosodium Glutamate-induced changes in rat cerebellar cortex: histological, immunohistochemical and electron microscope study. Ultrastruct Pathol 2023; 47:1-24. [PMID: 36803391 DOI: 10.1080/01913123.2023.2175943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 01/19/2023] [Accepted: 01/30/2023] [Indexed: 02/21/2023]
Abstract
Monosodium glutamate (MSG) is widely used as a flavor enhancer. Melatonin and garlic are well known as antioxidant. The present study was performed to evaluate the microscopic changes in the cerebellar cortex of rats after the administration of MSG and the possible protective effect of melatonin versus garlic on those changes. The rats were divided into four main groups. Group I (control group). Group II received MSG (4 mg/ g/day). Group III received MSG+ melatonin (10 mg/kg bw/day). Group IV received MSG+garlic (300 mg/kg bw/day). Immunohistochemical staining for glial fibrillary acidic protein (GFAP) was done as a marker for astrocyte demonstration. Morphometric study was done to assess the mean number and diameter of Purkinje cells, the number of astrocytes and the percentage area of positive GFAP immune stain. MSG group demonstrated congested blood vessels, vacuolations in the molecular layer, and Purkinje cells appeared irregular with nuclear degeneration. Granule cells appeared shrunken with darkly stained nuclei. The immunohistochemical stain for GFAP was less than expected in the three layers of the cerebellar cortex. Purkinje cells and granule cells appeared irregular in shape with dark small heterochromatic nuclei. The myelinated nerve fibers showed splitting and loss of the lamellar structure of their myelin sheath. Melatonin group showed that the cerebellar cortex was nearly similar to that of control group. Garlic treated group showed partial improvement. In conclusion, melatonin and garlic could partially protect against MSG induced changes and the protective effect of melatonin was better than garlic.

[PMID: 36257342 DOI: 10.1016/j.jep.2022.115840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/09/2022] [Accepted: 10/12/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Approximately 80% of people in developing countries depend on medicinal plants for their health care. Tridax procumbens (T. procumbens) and Allium sativum (A. sativum) have beneficial effects against parasitic and bacterial diseases. On the other side, the biological activity of the oxylipin (3S)-16,17-didehydrofalcarinol isolated from T. procumbens against the parasite Leishmania mexicana has been verified. AIM OF THE STUDY To evaluate the acute oral toxicity of the methanolic extract of T. procumbens, the aqueous extract of A. sativum, their mixture, and pure oxylipin (3S)-16,17-didehydrofalcarinol in BALB/c mice. MATERIALS AND METHODS Doses of 2000 and 5000 mg/kg of the methanolic extract of T. procumbens, the aqueous extract of A. sativum, and their mixture (1:1), and doses of 300 and 500 mg/kg of pure oxylipin were administered orally to female mice of the strain BALB/c, which were observed for 72 h in search of signs of toxicity. After 14 days, the animals were euthanized, blood was extracted for the measurement of transaminases, and the livers were recovered and stained with hematoxylin/eosin for histopathological analysis. RESULTS No clinical signs of toxicity were observed in any of the animals dosed with T. procumbens and A. sativum extracts, while the majority of the animals dosed with pure oxylipin showed signs of toxicity and died. There was no difference in the weight index in most of the animals, except for the animals treated with T. procumbens at doses of 2000 mg/kg who presented an increase in the weight index, nor was there a correlation between the dose of A. sativum and the mixture and food consumption; however, a direct proportional correlation was observed between T. procumbens dose and food consumption. In none of the animals dosed with T. procumbens, A. sativum, and the mixture there was a difference in the levels of transaminases. In the histopathology study, slight lesions were observed in the hepatocytes of the mice treated with T. procumbens, A. sativum, and their mixture at doses of 2000 and 5000 mg/kg. On the other side, moderate injuries were observed in animals treated with pure oxylipin and it was considered as toxic due to almost all the animals died. CONCLUSION The extracts of T. procumbens and A. sativum evaluated and applied orally did not cause signs of acute toxicity or severe liver damage, suggesting to evaluate their chronic toxicity including other biochemical parameters in the future. However, pure oxylipin caused signs of acute toxicity and death so it is recommended to work with lower doses.

Abstract
Among the alternatives to control avian coccidiosis, alliaceous extracts stand out due to their functional properties. Despite this, most of the references are focused just on garlic. In this study, we analyze the in vitro effects of propyl-propane thiosulfinate (PTS) and propyl-propane thiosulfonate (PTSO), two organosulfur compounds from onion, on MDBK cells infected with sporozoites of Eimeria acervulina. To this aim, two different experiments were performed. In the first experiment, sporozoites were previously incubated for 1 h at 1, 5 and 10 µg/mL of PTS or PTSO and added to MDBK cells. In the second experiment, MDBK cells were first incubated for 24 h at different concentrations of PTS or PTSO and then infected with E. acervulina sporozoites. Then, 24 h after inoculation, the presence of E. acervulina was quantified by qPCR. MDBK viability was measured at 72 h post-infection. Sporozoites incubated at 10 µg/mL of PTS and PTSO inhibited the capability to penetrate the cells up to 75.2% ± 6.44 and 71.7% ± 6.03, respectively. The incubation of MDBK with each compound resulted in a preventive effect against sporozoite invasion at 1 µg/mL of PTS and 1 and 10 µg/mL of PTSO. Cells incubated with PTSO obtained similar viability percentages to uninfected cells. These results suggest that the use of PTS and PTSO is a promising alternative to coccidiosis treatment, although further in vivo studies need to be performed.

Abstract
Albendazole (ALB) is the most used therapeutic drug for trichinellosis treatment, but it has many drawbacks. Hence, the search for alternative natural compounds is a goal for researchers. The present work aimed to test the in vitro anthelmintic effect of Tomex (Allium sativum) against adult and muscular larva of Trichinella spiralis (T. spiralis). We incubated adult forms and muscular larvae of T. spiralis with Tomex at concentrations 10, 50, and 100 μg/mL to evaluate the changes that happened on the cuticle using a scanning electron microscopy (SEM). Although ALB was very effective, Tomex also affected motility and the tegumental structure of T. spiralis, which was in proportion to its concentration and incubation time, as Tomex started the mortality of muscular larvae and adult stages after 4 h at 50 μg/mL, and after 6 h at10 μg/mL. A 50% mortality rate of muscular larvae was recorded after 6 h at 100 μg/mL. However, a 50% mortality rate was recorded after 12 h at 10 μg/mL for the adult stage. Adult worms and muscular larvae of T. spiralis incubated with 100 μg/mL of Tomex displayed loss of normal annulations and creases of the cuticle, multiple vesicles, widening of longitudinal furrow space, and multiple minor loss blebs. Our results suggested that Tomex can be a therapeutic agent against adults and larvae stages of T. spiralis.

Abstract
Fruits and vegetables (FVs) have long been a major source of nutrients and dietary phytochemicals with outstanding physiological properties that are essential for protecting humans from chronic diseases. Moreover, the growing demand of consumers for nutritious and healthy foods is greatly promoting the increased intake of FVs. Allium (Alliaceae) is a perennial bulb plant genus of the Liliaceae family. They are customarily utilized as vegetable, medicinal, and ornamental plants and have an important role in agriculture, aquaculture, and the pharmaceutical industry. Allium plants produce abundant secondary metabolites, such as organosulfur compounds, flavonoids, phenols, saponins, alkaloids, and polysaccharides. Accordingly, Allium plants possess a variety of nutritional, biological, and health-promoting properties, including antimicrobial, antioxidant, antitumor, immunoregulatory, antidiabetic, and anti-inflammatory effects. This review aims to highlight the advances in the research on the bioactive components, physiological activities and clinical trials, toxicological assessment for safety, and applications of different Allium plants. It also aims to cover the direction of future research on the Allium genus. This review is expected to provide theoretical reference for the comprehensive development and utilization of Allium plants in the fields of functional foods, medicine, and cosmetics.

Abstract
Purpose At present, the chemotherapy for alveolar echinococcosis (AE) is mainly based on albendazole (ABZ). However, more than 20% of patients fail chemotherapy. Therefore, new and more effective treatments are urgently needed. Allicin has been reported to have antibacterial and antiparasitic effects. The objectives of the present study were to investigate the in vivo and in vitro efficacy of allicin against Echinococcus multilocularis (E. multilocularis). Methods The effects of allicin on protoscolex survival and structural changes were evaluated in vitro. The 4-week-old BALB/c male mice used for in vivo modelling underwent inoculation of E. multilocularis protoscoleces by intraperitoneal injection, followed by intragastric administration of allicin for 6 weeks. Then, the effects of allicin on lymphocyte subsets, metacestode growth and host tissue matrix metalloproteinase 2 (MMP2)/MMP9 expression around metacestodes in mice were evaluated. The toxicity of allicin was further evaluated in vivo and in vitro. Results Att 40 μg/mL, allicin showed a killing effect on protoscoleces in vitro and treatment resulted in the destruction of protoscolex structure. Molecular docking showed that allicin could form hydrogen bonds with E. multilocularis cysteine enzymes. After 6 weeks of in vivo allicin treatment, the spleen index of mice was increased and the weight of metacestodes was reduced. Allicin increased the proportion of CD4+ T cells and decreased the proportion of CD8+ T cells in the peripheral blood and spleen. Pathological analysis of the metacestodes showed structural disruption of the germinal and laminated layers after allicin treatment. In addition, allicin inhibited the expression of MMP2 and MMP9 in metacestode-surrounding host tissues. At 160 μg/mL, allicin had no significant toxicity to normal hepatocytes but could inhibit hepatoma cell proliferation. At 30 mg/kg, allicin had no significant hepatorenal toxicity in vivo. Conclusion These results suggest that allicin exerts anti-E. multilocularis effects in vitro and in vivo and can enhance immune function in mice, with the potential to be developed as a lead compound against echinococcosis.

Abstract
Garlic is one of the most widely employed condiments in cooking. It has also been used since ancient times in traditional plant-based medicine, largely based on its organosulfur compounds. The objective of this study was to provide updated information on the biological and therapeutic garlic properties. Garlic has been found to possess important biological properties with high therapeutic potential, which is influenced by the mode of its utilization, preparation, and extraction. It has been attributed with antioxidant, anti-inflammatory, and immunomodulatory capacities. Garlic, in particular its organosulfur compounds, can maintain immune system homeostasis through positive effects on immune cells, especially by regulating cytokine proliferation and expression. This may underlie their usefulness in the treatment of infectious and tumor processes. These compounds can also offer vascular benefits by regulating lipid metabolism or by exerting antihypertensive and antiaggregant effects. However, further clinical trials are warranted to confirm the therapeutic potential of garlic and its derivatives.

Abstract
Dietary organosulfur-containing compounds (DOSCs) in fruits, vegetables, and edible mushrooms may hold the key to the health-promotion benefits of these foods. Yet their action mechanisms are not clear, partially due to their high reactivity, which leads to the formation of complex compounds during postharvest processing. Among postharvest processing methods, thermal treatment is the most common way to process these edible plants rich in DOSCs, which undergo complex degradation pathways with the generation of numerous derivatives over a short time. At low temperatures, DOSCs are biotransformed slowly during fermentation to different metabolites (e.g., thiols, sulfides, peptides), whose distinctive biological activity remains largely unexplored. In this review, we discuss the bioavailability of DOSCs in human digestion before illustrating their potential mechanisms for health promotion related to cardiovascular health, cancer chemoprevention, and anti-inflammatory and antimicrobial activities. In particular, it is interesting that different DOSCs react with glutathione or cysteine, leading to the slow release of hydrogen sulfide (H2S), which has broad bioactivity in chronic disease prevention. In addition, DOSCs may interact with protein thiol groups of different protein targets of importance related to inflammation and phase II enzyme upregulation, among other action pathways critical for health promotion. Expected final online publication date for the Annual Review of Food Science and Technology, Volume 13 is March 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract
The menace of the enfeebling disease leishmaniasis prevails due to the inaccessibility of effective vaccine and chemotherapy. Hence in the pursuit of finding novel alternative options with reasonable efficacy, immunomodulation, leishmanicidal activity and fewer side effects, screening of compounds from natural sources is needed. This study was focused on in vitro and in vivo antileishmanial screening of gallic acid (GA) against Leishmania donovani infection in BALB/c mice. GA showed in vitro parasiticidal activity and IC50 value of 19.59 ± 0.74 µg/ml and is able to arrest cell cycle at the sub-G0/G1 phase. The therapeutic potential of gallic acid was assessed in the L. donovani-infected BALB/c mice. GA reported a reduction in parasite burden and augmentation of CD4+ and CD8+ T lymphocytes. Also, the polarization of mouse immune status to protective Th1 response was evidenced by increased delayed-type hypersensitivity response and levels of IgG2a, reactive oxygen species and nitric oxide. GA was reported to be safe and non-toxic to human cell line THP-1 and also to the liver and kidney of mice. Hence, the findings of the present study indicate the possible role of GA in the strengthening of host immune system and thus facilitating the clearance of leishmanial infection and conferring protection.

Abstract
The chemical constituents of Allium sativum (garlic) oil were investigated using the GC/MS technique after silylation, and the presence of several fatty acids and their esters was revealed. The most dominant was 9,12-octadecadienoic acid (linoleic acid), a precursor of arachidonic acid, which is essential for brain development. Garlic oil-loaded chitosan nanoparticles (GCNs) were prepared to enhance its cerebral effects, and to mask its odor and taste. Two-level orthogonal factorial design, followed by regression analysis, was used to study the influence of different formulation variables. GCN3, the formula with the smallest particle size and the highest mucoadhesion, was selected as the optimized one. Transmission electron microscopy showed that GCN3 has a short nanorod-shape outline. We aimed to investigate the influence of orally administered GCN3 compared to the plain garlic oil (GO), on ciprofloxacin-induced (CPX) neurotoxicity in rats and the probable underlying mechanisms. The results show the significantly higher neurological curative effect of GCN3 compared to GO, and its greater antidepression-like and antianxiety-like potential via the alteration of brain neurotransmitter levels and inhibition of oxidative stress and inflammatory pathways. The histopathological examination showed the higher capability of GCN3 to repair the damage induced by CPX in the cerebral cortex, hippocampus area and substantia nigra brain sections. Similar results were proved immunohistochemically using Cox-2 antibody. The nanoencapsulation of GO represents a promising strategy for brain-targeting.

Abstract
Garlic is a polyphenolic and organosulfur enriched nutraceutical spice consumed since ancient times. Garlic and its secondary metabolites have shown excellent health-promoting and disease-preventing effects on many human common diseases, such as cancer, cardiovascular and metabolic disorders, blood pressure, and diabetes, through its antioxidant, anti-inflammatory, and lipid-lowering properties, as demonstrated in several in vitro, in vivo, and clinical studies. The present review aims to provide a comprehensive overview on the consumption of garlic, garlic preparation, garlic extract, and garlic extract-derived bioactive constituents on oxidative stress, inflammation, cancer, cardiovascular and metabolic disorders, skin, bone, and other common diseases. Among the 83 human interventional trials considered, the consumption of garlic has been reported to modulate multiple biomarkers of different diseases; in addition, its combination with drugs or other food matrices has been shown to be safe and to prolong their therapeutic effects. The rapid metabolism and poor bioavailability that have limited the therapeutic use of garlic in the last years are also discussed.

Abstract
Leishmaniasis are diverse group of diseases caused by numerous species of genus Leishmania. Herein we have contrived a systematic review and meta-analysis on the prevalence of Leishmania species in rodents of Iran. For this purpose, following the general methodology recommended for systematic reviews and meta-analysis, six English databases (PubMed, Science Direct, Scopus, Ovid, Web of Science and Google Scholar) and four Persian databases (Magiran, SID, Iran Doc and Iran Medex) were explored during January 1995 till June 2015. Papers were selected based on 8 pre-defined inclusion criteria. During the years, a total number of 4485 different rodents were captured; among which 1291 cases were Leishmania positive. The calculated weighted prevalence of Leishmania species in rodents was 23% (95% CI=18-28). Given geographical zones of Iran, the highest and lowest prevalence rate was belonged to North 50% (95% CI=40-61) and West 11% (95% CI=5-17), respectively. Rhombomys opimus (1766), Meriones lybicus (1258) and Tatera indica (488) were the three most abundant captured rodents, while the highest prevalence of Leishmania species was observed in Nesokia indica 48% (95% CI=42-54) and followed by R. opimus 39% (95% CI=30-47). Egger's regression test was performed to detect publication bias, which revealed it may not have a significant influence on overall weighted prevalence estimate (P=0.317). Meta-regression analysis demonstrated that there is no significant relationship between overall prevalence with sample size (P=0.1) and year of publication (P=0.7). The results showed remarkable prevalence of Leishmania species in rodent reservoirs. In future, adopting a suitable strategy for control and combat with rodents is necessary.

Abstract
BACKGROUND Leishmaniasis is a parasitic disease that appears with a range of symptoms including cutaneous, mucocutaneous, and visceral leishmaniasis. The present study sought to determine the antileishmanial effect of the extract of Artemisia dracunculus (Tarragon) compared to control treatment with pentavalent antimony (meglumine). METHODS This experimental study was performed in 2014-2015. A. dracunculus were collected from West Azerbaijan Province, Iran and dried; then the ethanolic extract of the plant was prepared. The effect of different concentrations of Artemisia's extract was compared with Glucantime ® in the stationary phase by MTT colorimetric assay and Trypan blue staining. Human peripheral blood mononuclear cells (HPBMCs) treated with L. major and production of IFN-γ and IL-4 cytokines measured at concentrations of 25, 20, 10 and 5μg/ml A. dracunculus. RESULTS Treatment with the extract did not affect the survival of the parasites during the first 48 h; however, on the third day (72 h), all concentrations significantly reduced the number of parasites with an efficacy of more than 50% at 10 μg/ml (P<0.01), 20μg/ml (P<0.001), and 25 μg/ml (P<0.0001). Moreover, IFN-γ and IL-4 secretion from the HPBMCs was significantly affected in a dose-dependent manner, compared to the control (no extract). The IFN-γ/IL-4 ratio further confirmed this notion. CONCLUSION A. dracunculus extract cannot only exert potent antileishmanial activity but may also enhance cellular immunity to this parasite. Further studies are required to determine the main compound(s) responsible for these effects of the plant.

Abstract
Leishmaniasis is a tropical parasitic infection. The resistance and toxicity issues are the major complications and remain significant consequences related to the treatment of leishmaniasis with the recent and classical drugs. Thus there is an immediate requirement to develop new compounds for the treatment of this protozoan disease. Sea cucumbers or holothurians are potentially presented as the marine sources of antimicrobial and cytotoxic compounds. The aim of this study was investigation of in vitro antileishmanial activity of methanol extract of body wall, coelomic fluid, and cuvierian organs of Holothuria leucospilota obtained from coastal parts of Persian Gulf against Leishmania infantum promastigotes and axenic amastigotes. The colorimetric MTT assay was used to determine L. infantum promastigotes and axenic amastigotes viability at different concentrations of the extracts and drug control (Glucantime®) at time dependent manner and the results are represented as IC50 (50% of inhibitory concentration). Coelomic fluid was the most active extract among the three different extracts of H. leucospilota against L. infantum promastigotes and axenic amastigotes with IC50s of 62.33 μg/mL and 22.4 μg/mL and 73 μg/mL and 46 μg/mL at 48 and 72 hours after treatment, respectively. Cuvierian organs extract showed less toxicity with IC50s more than 1000 μg/mL for both Leishmania infantum axenic amastigotes and promastigotes forms after 48 and 72 hours of exposure. Results acquired from the present study propose that the sea cucumber H. leucospilota may be a provoking source of antileishmanial compounds and could be a lead source in the development of the potent antileishmanial and cytotoxic drugs.

Abstract
BACKGROUND The present study aimed to survey antileishmanial activity of methanolic Holothuria leucospilota extract against Leishmania major promastigotes in vitro. METHODS Promastigotes were cultured in RPMI 1640 and after reaching the stationary phase, the study was conducted with different concentrations of the extract. Afterwards, MTT colorimetric assay for the obtaining of 50% inhibitory concentration (IC50) was utilized. Furthermore, in order to determine the possible induction of apoptosis in L. major promastigotes, flow cytometry and DNA fragmentation methods were employed using annexin-V FLUOS staining kit and DNA ladder kit, respectively. RESULTS The IC50 value of H. leucospilota extract at three time points of 24, 48, and 72 h was estimated 2000, 300 and 85 μg/ml, respectively. In addition, the extract revealed a dose and time-dependent antileishmanial activity. Furthermore, various characteristics of apoptosis appeared after L. major promastigotes treatment, which included cell shrinkage, formation of apoptotic bodies, blebbing of the cell membrane, and externalization of phosphatidylserine, although no laddering pattern was observed. CONCLUSION The methanolic extract of H. leucospilota possesses lethal effect on L. major promastigotes and induces the apoptosis in parasites. Further studies are required to address the apoptosis mechanism in vivo.
