The use of antibiotics in humans and animals has been marked as a significant step in health due to their effectiveness in controlling and treating bacterial infections. The misuse and overuse of antibiotics have been identified as risk factors for bacterial resistance since microorganisms adapt and develop mechanisms to defend against antibiotics. According to the Centers for Disease Protection and Control (CDC), around 23,000 individuals die every year in the United States due to antibiotic resistance complications. As a result, a demand for alternative treatments has been a goal for scientists as the microbes adapt to selective pressure. The aim of this study is to test the antibacterial activity of leaf extracts of Peganum harmala and Haloxylon salicornicum on both Gram-positive and Gram-negative bacteria on various mediums. The results of the study showed that both P. harmala and H. salicornicum inhibited the bacterial growth in two different media. The results were also compared with different common antibiotics used in both human’s and animal’s fields and showed a promising outcome as alternative antibiotics. 展开更多

Normal body cells multiply in a controlled manner and undergo apoptosis when the body no longer needs them. Different types of cancers exist, and the common ones include breast, cervical, prostate, lung, colon, and skin cancers. Several factors have been associated with cancers, and these factors include poor dieting, exposure to harmful chemicals and radiation, weak immune system, and genetics. Cancer presents an enormous health threat in the modern world and thus the need to identify an effective treatment. The conventional treatments used in the management of cancer include chemotherapy and physiotherapy. These forms of cancer treatments usually have enormous side effects on the subjects. In this respect, an alternative form of treatment would be effective in managing cancer patients. A substantial number of natural products have been observed to be effective in the management of cancer. These natural products include plants and other natural substances such as honey. This study focuses on the efficiency of natural products in the treatment of cancer. Also, the anticancer effects of Peganum harmala, Manuka honey, and Saudi honey will be analyzed. Bee honey and Peganum harmala have been traditionally used in the treatment of cancer. The extracts from Peganum harmala plant have also been shown to exhibit divers’ antitumor effects similar to the mode of action of a vast number of anticancer agents. These established hypotheses thus give the rationale for this study. In this experiment, extracts were obtained from Peganum harmala leaves and exposed to cervical, lung, and prostate cancer cells. Similarly, solutions of Manuka honey and Saudi honey were exposed to the cervical, lung, and prostate cancer cells. The experiment duration was 24 hours, which obtained results were recorded and analyzed. Peganum harmala extracts inhibit cancer cell growth at different and achievable concentrations. Manuka honey highly inhibits the growth of HeLa cancer cells while Saudi honey highly inhibits the growth of A549 cells. Peganum harmala can form an effective treatment for managing several types of cancers. Manuka Honey can be applied as an effective treatment for managing cervical cancer while Saudi honey can form an effective treatment for managing lung cancers. 展开更多

Cancer is a worldwide disease that ranks as the second-largest cause of death after cardiovascular disease. In 2019, the estimated number of cancer deaths was around 10 million worldwide and 600,000 in the United States. Due to the high side effects of the available treatments for cancer, such as chemotherapy and radiotherapy, a demand for alternative treatments has been a goal for scientists with less toxicity and side effects. Lung cancer is the most common type of cancer worldwide and the leading cause of death in the United States. In addition, prostate cancer is the second-leading cause of cancer death in American men after lung cancer. Natural sources discovered to have therapeutic medicinal properties against human diseases are the plants Peganum harmala and Haloxylon salicornicum. The aim of this study is to test the anticancer activity of leaf extracts of Peganum harmala and Haloxylon salicornicum on lung cancer (A549) and prostate cancer (PC3) cell lines. The anticancer activity of P. harmala and H. salicornicum was studied using the assays: crystal violet viability, lipid peroxidation, and caspase-3 techniques, which were evaluated in vitro on two human cancer cell lines. The results of the study showed that both plants’ extracts reduced the viability of both cancer cell lines, which depended on the concentration of the extract. Also, P. harmala showed more potent activity against both types of cancer than H. salicornicum. P. harmala and H. salicornicum decreased the lipid peroxidation that induces cancer as well as increased the expression of caspase-3, which causes apoptosis and cell death. This study concluded that P. harmala and H. salicornicum leaf extracts showed significant anticancer properties, which might be due to the presence of phytochemicals, including flavonoids and phenolics. 展开更多

OBJECTIVE: To review the pharmacological activities of Peganum harmala L.(P. harmala, Nitrariaceae) in traditional Iranian medicine(TIM) and modern phytotherapy.METHODS: Opinions of TIM and modern phytotherapy about safety and acceptable dosage of this plant are discussed. Various medical properties of P.harmala were collected from important TIM references and added to scientific reports derived from modern medical databases like Pub Med, Scirus, Science Direct and Scopus.RESULTS: The main medicinal part of the plant is the seed. In TIM resources, this plant possesses various Pharmacological activities such as carminative,galactagogue, diuretic, emmenagogue, antithrom-botic and analgesic. In modern phytotherapy, P. harmala demonstrated numerous medicinal effects including cardiovascular, neurologic, antimicrobial,insecticidal, antineoplasmic, antiproliferative, gastrointestinal and antidiabetic effects. Adverse events such as neuro-sensorial symptoms, visual hallucination, bradycardia, hypotension, agitation,tremors, ataxia, abortion and vomiting cause people to use this plant cautiously. P. harmala is contraindicated during pregnancy, due to its abortive and mutagenic activities. Because of increasing the expression of CYP1A2, 2C19, and 3A4 and inhibition of monoamine oxidase, the pharmacokinetic parameters of drugs which are mainly metabolized by these enzymes may be affected by P. harmala.CONCLUSION: The medicinal properties declared for this plant in TIM are compared with those showed in modern phytotherapy. Some of the TIM properties were confirmed in modern phytotherapy like emetic and analgesic activities and some have not been evaluated in modern phytotherapy such as its therapeutic effects on paralysis, epilepsy and numbness. Finally, the current review provides the evidence for other researchers to use TIM properties of P. harmala as an efficacious natural drug.Further preclinical and clinical studies for adequate evaluating safety and therapeutic efficacy are recommended. 展开更多
